BACKGROUND OF THE DISCLOSURE
• Many needs of parking management, especially in on-street parking environments in urban areas, are not being met with current technology, despite severe needs to improve parking in cities around the world. The ability to automate payment for parking spaces, reserving parking spaces, especially for freely accessible spaces such as on-street parking, and provide convenient choices that combine on-street and off-street to motorists has been elusive due to limitations of current technology. Parking management systems that include accurate space occupancy detection do not include unique vehicle identification for vehicle-based parking access and rate determination, motorist guidance, violation detection, and enforcement automation support. These needs are global, have existed for a long time, but there has not been any successful implementation of a parking management system as disclosed herein.
• Public parking spaces are valuable, limited and can include shared real estate. Public parking spaces impact economic development, city finances, public safety, and citizen happiness. In many cities, challenges including traffic congestion resulting from motorists circling the block due to inadequate parking supply/demand management, and the inability to incentivize beneficial use patterns and discourage abuse of public spaces results in citizen unhappiness, quality of life impact, congestion, pollution, revenue loss, economic impact to businesses, and also projects a poor image of the cities. The ability to provide motorists best-fit choices whether on-street and off-street and the ability to provide certainty of finding a parking space provides tremendous value to motorists, cities and parking operators.
• Failed approaches to solving the problem of providing certainty to motorists includes electro-mechanical stoppers in each space (failures in devices damage vehicles, motorist confusion to drive over the stopper), passive RFID tags or beacons to uniquely identify vehicles (requires high powered transponders close to the tag, not compatible with battery operated parking devices), GPS based vehicle location (poor spatial accuracy, especially in dense urban areas), applications that require extensive hands-on interfaces, and inaccurate parking space occupancy detection. Due to these failures, reservations in the current art are limited to human operators facilitating the reservation and therefore are of very limited use.
• Reservations capability provides a high level of certainty to motorists and becomes even more important for the very small inventory of special purpose spaces such as for EV charging or ride share vehicles.
• In addition, there exists a demand for parking management of 2 wheelers and trucks.

Each block may have an associated processing machine or the blocks depicted may be carried out through one processor machine. Furthermore, while the steps may be shown in a particular order, it should be appreciated that the steps may be conducted in a different order.
• What is needed is to solve critical challenges that include providing systems and methods for accurate parking space detection, battery operated time-of-flight ranging tags to locate the precise parking space a vehicle is occupying, and on-street infrastructure that provides complete information to motorists and enables complete workflows and exception and violation management, automated natural language voice interfaces for parking management, and secondary evidence imagers to manage exception conditions and violations.
• In some examples, a system may comprise a fixed unit having a sensor with a zone of detection that corresponds to at least one parking space; a reservations indicator to indicate status of the space with the ability to display specific user identifiers such as license plate or reservation holder's name or identifier; one or more processors configured to communicate between the sensor and the reservations indicator; one or more processors configured to communicate between the sensor and a central server, one or more processors configured to communicate between the reservations indicator and the central server or a user device; a mobile or in-vehicle app or user interface for a user to request a reservation or see available reservations; a natural language voice processor for convenient user interaction, especially while driving; and a guidance display indicating a number of parking spaces available in a given zone or direction, wherein the guidance display is updated based on occupancy information for each parking space collected by the roadside unit.
• In some examples, a system may comprise one or more sensors configured to communicate with one or more user applications, directly or via an intermediate server, to detect arrival and parking of vehicle in a zone of detection, determine if a space is currently reserved for a reservation holder, request confirmation from the user via an indication on the user's mobile or in-car device and in case no confirmation is received, trigger exception processing that may include any one or more of alerting an operator, using secondary evidence to determine identity of the parked vehicle and state of the space, send data to one or more violations processing systems, reserve an alternative space for the valid reservation holder, change the reservations indication on an alternate space, and inform the reservation holder via an application notification, SMS or phone call about the alternate space assignment.
• The systems and methods disclosed herein may apply to multi-wheeled vehicles, such as two-wheeled and/or four-wheeled motor vehicles, including automobiles, trucks, sport utility vehicles, motorbikes, mopeds, motorcycles, connected cars, autonomous vehicles, etc. As described above, a solution is needed for an integrated effort that helps build smart cities, eliminate inefficiencies, deliver high-quality services to citizens, and generate revenues. As further described herein, such a solution may include one or more of vehicle identification and management systems, guidance systems, mobile enforcement and field service systems, parking meter and space management systems, vehicle sensing systems configured to provide reliable and real-time data, comprehensive management and smart data systems, and mobile guidance applications. In addition to solving the above-identified challenges, the solution reduces risk and ensures interoperability between the various systems.
• A reservation system in a non-access controlled area where non-reservation holders may access a space that requires the ability to sufficiently display the reservation state of the space, preferably a clear message that identifies the reservation holder, and the system must automatically detect when a new vehicle enters or a vehicle exits the space and change its indication based on those events, and verify the identity of the vehicle occupying the space and verify if the correct vehicle is parked in the space.
• Accurate vehicle identification is a key enabling component of the reservation system. In a dense parking lot, or on the roadside, there may be other vehicles surrounding the parking space in adjacent spaces or movement lanes. Reliably identifying the vehicle in a space requires a positioning accuracy of less than 10 feet. This level of accuracy is not possible with GPS and other conventional systems, but is possible by using locating techniques, including distance measurement between a fixed device, such as a sensor, and a vehicle mounted device, such as an in-car device.
• While in-vehicle devices as disclosed may solve the problem of locating and identifying a vehicle in a parking space, in-vehicle devices are sometimes expensive and it is not always possible to have the devices in all vehicles. In cases when a vehicle pulls into a reserved space without an in-vehicle device to communicate with the sensor or the reservations indicator, the correct vehicle may be verified once it has pulled into a space by asking the actual reservation holder to confirm if they pulled into the space. While this is an extra step, this may be done by transmitting a message to the reservation holder and asking the user to confirm via a user device, but it is also possible to instruct the reservation holder ahead of time to proactively confirm upon their arrival.
• Enabling the parking reservations workflow via voice interaction using an automated voice processing engine, including one or more processors, will greatly assist users and enhance driver safety. Public parking systems need to cater to a wide range of users and often in areas with multi-lingual needs. For example, an intelligent voice engine may ask a user for critical information about their parking needs, prompt the user for missing information, and provide a recommendation or one or more choices to the user, and then also confirm the reservation and switch to navigation to provide directions.
• As disclosed herein, the systems and methods enable advanced parking management features in a meter-less configuration, thereby potentially avoiding a large portion of capital and operating expenses to cities (in parking meters and the like), and are preferably battery operated and may be solar powered. It is expensive to trench power and data cables to various on-street equipment such as reservation indicators and sensors, though it is possible to do so. The in-vehicle device is preferably battery operated with a self-contained battery.
• When used in a building, using power derived from a mains source makes it possible to power the in-vehicle device.
• As disclosed herein, stationary or moving vehicles may be accurately and uniquely identified from very low power infrastructure components and display reservations indications at the parking space using battery or solar power when used in an outdoor configuration.
• The disclosed systems and methods may be combined with on-street dynamic signage and guidance to motorists, and integrated with collection and enforcement systems, including booting and towing systems violating vehicles.
• The disclosed systems and methods may also be suited for situations and/or environments where a vehicle needs to be uniquely identified in order to apply vehicle specific business rules for access grant, permitted length of stay, payments, discounts, accounting, etc.
• In some examples, the systems and methods may be configured to detect a vehicle momentarily parked or entering an area such as a garage entrance. If the vehicle is authorized or has a reservation for a space inside the garage, the sensor and the in-vehicle device with the ranging capability may be used to detect and validate the vehicle at a gate or access point at the garage entrance and operate an access control.
• In some examples, the systems and methods may have the reservations indicator collocated with a directional time of flight radar sensor or another suitable vehicle occupancy sensor that includes a defined zone of detection coinciding with a zone of interest in a parking space. Configurations, including pole mount or curb mount, may be used in this context and the sensor and the reservations indicator may share one or more of mounting structures, enclosures, battery, and communication means.
• In some examples, the systems and methods may have the reservations indicator on a short pole near the space, such that it is clearly associated with the space with a LED or backlit LCD display.
• While space specific indicators are less confusing to motorists, indications for 2 or more spaces in a common indicator device may be displayed. Larger dynamic message signs may comprise one or more multi-space indicators.
• The in-vehicle device may be mounted at a convenient location, such as behind the windshield or the back glass of the vehicle or may be mounted on the exterior or the underside of the vehicle chassis at a suitable location. Though it is referred as in-vehicle device and may be mounted in an interior or in the vehicle, the device will have the same primary function if mounted on the exterior of the vehicle, such as attached to a license plate, license plate frame, or mounted underneath the vehicle.
• The in-vehicle devices may utilize energy harvesting from ambient RF energy, light, or wind energy. The in-vehicle device may employ one or more beacons triggered periodically on a timer or based on the vehicle state using an accelerometer to initiate handshaking or pass data to the sensor or reservations indicator.
• In some examples, the systems and methods may combine any of reservations and sensor functions with a parking meter device. The parking meter may comprise a single, dual, or multi-space meter.
• In some examples, the systems and methods may combine electronic payment such as NFC with a reservations indicator.
• In some examples, the systems and methods may combine a passive space identifier such as RFID or 1D, 2D or 3D barcodes, or QR codes with the reservations indicator or sensor devices.
• FIG. 1 depicts an example schematic block diagram of aroadside unit configuration100. Thepower management section101 may utilize a battery, solar or other suitable power source that may be shared with a parking meter or provided by a utility. Thepower management section101 may ensure energy is being utilized optimally, thecontroller103 along with thesignal processor102 work together to operate the device and process raw analog data from anoccupancy sensing radar109. In addition theRF transceiver104 can be frequency and power level controlled internally within its own software. Anantenna switch107 may be used to shareantenna elements106,108 with theRF transceiver104.
• The communication between the in-vehicle device and a roadside transceiver in a sensor or reservations indicator may be implemented in many ways. Battery optimization on both the in-vehicle device and the roadside device may be a significant consideration in establishing the communication mechanism.
• For example, in the simplest form, the communication may be one-way, wherein the in-vehicle device emits a beacon with its unique ID and the roadside transceiver may listen for such beacon, either constantly or periodically and in conjunction with the occupancy state change events.
• The communication mechanism also may be two-way and can be initiated either by the in-vehicle device or by the roadside device. The two-way communication can be implemented even if the in-vehicle device is a passive device, such as, for example, a passive RFID tag or other like passive device.
• The two-way communication can enable many security schemes, such as challenge-response and other encryption schemes that can be difficult to tamper or copy. In various embodiments, the vehicle identification is used to either grant access for the vehicle or to provide treatment such as parking permits, length of stay or discounted parking, etc., as well as other fraudulent attempts that may be made to utilize these services.
• To aid in initial pairing or detection of the vehicle, the in-vehicle device may transmit its identification upon an accelerometer event, such as a deceleration detection or no acceleration detection for a threshold period of time in the axis of normal vehicle movements or engage its receiver for a period of time. Upon a change of occupancy state detected by the sensor, the sensor can initiate its' receiver window for a period of time to listen to a in-vehicle device beacon or transmit a beacon if the in-vehicle device is expected to be listening.
• The pairing communication may be in addition to a ranging measurement where the distance between the sensor and the in-vehicle device is measured.
• Since the in-vehicle device and the sensor are on separate clocks, it is possible the clock frequencies not dissimilar. To overcome clock frequency errors, ranging may be implemented as a two-way ranging with both the in-vehicle device and the sensor measuring the ranging distance to each other and the two measurements are averaged, largely canceling out the error.
• For example, the above-identified ranging may also be performed between a reservation indicator and other fixed parking devices such as a parking meter or gateway and the in-vehicle unit and the data may be aggregated to determine the specific parking space a vehicle is in.
• Ranging measurement between a transmitter and a receiver may be performed based on techniques that use a synchronization signal such as a marker pulse or a known pulse that is known by the receiver and may be used as a reference point by the receiver and techniques swept frequency transmissions with a known sweep rate, known delay timing elements, and retransmitting the original transmission or a known modification thereof. Such apriori knowledge or commonality between the transmitter and receiver and the delayed retransmission may provide adequate ranging for the purposes of localizing a vehicle in a specific spot. The localization can be further strengthened by using small temporal windows that are unique to the specific event.
• FIG. 2 depicts an example schematic block diagram200 of an in-vehicle unit209 withaccelerometer210 andoptional GPS capability215. In this example configuration, abattery212 may provide power for the entire unit.Controller211 may execute program instructions and may controlRF transceiver214 which couples with theantenna216 and avisual indicator218 and abuzzer217.
• In other examples, the in-vehicle device209 may determine the parking state of the vehicle through an interface to a car's computer such as an OBD diagnostic interface or a Bluetooth or other wired or wireless vehicular network. In these cases, if the in-vehicle device receives a specific notification indicating the transmission has been put into a parking state or the parking brake is engaged, or the acceleration has stopped for a period of time, the in-vehicle device will receive an accurate parking event notification.
• The specific determination of the location of a vehicle in a parking space by using any combination of sources from sensor event change time, vehicle acceleration data from an accelerometer or car computer data, and ranging distance measurement between the in-vehicle device and the sensor or other roadside units enable the system and methods for very reliable and suitable for general use. The use of vehicle acceleration data enables the in-vehicle device209 to limit its transmit or receive times enabling low-power battery operation of the device209.
• In some embodiments, a button may be provided on the in-vehicle device209 to initiate transmission to the sensor in case the initial handshaking or pairing failed. Upon pressing or activating the button, the in-vehicle device209 may transmit a longer preamble in order to wake-up the sensor or other roadside device to ensure they can pair even if they are outside the initial pairing window. While this additional preamble takes battery power from the in-vehicle device209, it provides the motorist an ability to force the pairing in the event there was a system error or there was an abnormal parking situation.
• The in-vehicle device209 may further include one or more of visual and auditory indications.
• In other examples, the persistence of the in-vehicle device209 with respect to the sensor or other roadside devices may be used to differentiate between vehicles in the zone of interest, such as a parked car from other nearby transitory vehicles.
• In various embodiments, sensors can use laser, visible, near infra-red (NIR) or infra-red (IR) light emitting diode (LED) or laser diodes, ultrasound, NIR or IR triangulation based sensors with or without a linear photo sensor array, frequency modulated continuous wave (FMCW), Doppler, inductance sensing, imaging, passive acoustic, optical disturbance or other techniques for vehicle detection.
• In various embodiments, the unique vehicle identification can be used for automated payment remittance or account charges, or payments to be calculated and charged based on the time the vehicle is parked as calculated after the vehicle departs. To accomplish this, the roadside device may be communicatively coupled to one or more parking payment systems. The communicative coupling may be wireless and/or wired. In various embodiments, a cellular connection may be used. The parking payment systems may have a variety of embodiments and may be co-located with the roadside device or may be remotely located or a combination thereof. For example, the parking payment system may be a parking meter or a parking pay station located at a central location to a number of parking spaces, such as, for example, in a parking garage. Also, based on the vehicle identification and the business and privacy rules set and the type of service, localized information or advertisements can be sent to an in-vehicle device or the user's cell phone or smartphone. This can be used to send reminders or other pertinent messages to the user via their smart phone, cell phone, email, tablet computing device, or other electronic means.
• In various embodiments, a collection of roadside devices may listen to the in-vehicle device209 either in a synchronized manner or not and report their signal strengths to the server and the pattern of received signal strengths can be used alone or in conjunction with other information to further narrow down the location of the in-vehicle device209.
• In various embodiments, the in-vehicle device209 or the roadside device may incorporate a fixed delay element with an antenna element tuned to a frequency for the purposes of retransmission of the incoming signal.
• In some embodiments, the delay element is longer than the transmit burst and effectively simulates a transmission path much longer than that of a physical transmission path. This allows for longer transmission pulses relative to the distance which will be easier to implement in the electronics.
• In some embodiments, swept frequency transmissions are used and the frequency offset between the roadside and in-vehicle devices may be mitigated by initiating a ranging measurement from both devices, among other techniques.
• In some embodiments, a synchronization signal such as a sub-microsecond burst from a gateway device that is sufficiently far and at an angle from each of the devices in a way that its signal arrives at the in-vehicle device at near the same time or with a known time lag or lead relative to the roadside device also may be incorporated into the roadside device. The sync signal starts an analog or digital timing circuit in either the roadside or the in-vehicle device and is also reflected from the other device with the fixed delay element after the fixed time delay. The time difference between the sync and the reflected signals can be measured using the analog or digital timing means as a way of determining the distance between the in-vehicle and the roadside device. If more than one roadside device participates in the timing, the information can be uploaded to a server or shared among the roadside device in order to triangulate and further precisely determine the location of the in-vehicle device in relation to the roadside device. This method can determine whether an in-vehicle device is in a near-by parked vehicle or in a further away transit lane. An analog timing circuit, such as a ramp voltage with a 100 ns peak-peak duration can be implemented with relative ease and the time gap between the two signals can be easily measured and can be repeated to remove spurious and noise readings. Instead of a fixed delay element, one of the devices also can be designed to transmit a burst after a preset delay. A precision timing circuit, such as those disclosed in the broad spectrum radar timing generator, also can be used for timing or the digital or analog timing circuit o the broad spectrum radar can be used for this timing.
• In various embodiments, the in-vehicle209 and/or the roadside device may use a specially adapted beacon or synchronization burst that is less than a millisecond, sometimes less than 10 μs or even less than 1 μs, that may be modulated with small amounts of data for synchronization or for broadcasting full or partial vehicle IDs. Such small bursts may be useful in saving battery life and serving as a synchronization reference may be implemented by adapting an ISM band radio transceiver, for example one primarily meant for 802.15.4 communications by hardware and/or software adaptations.
• A plurality of antenna elements can be used in the roadside transceiver to narrow down the direction of arrival of the in-vehicle transceiver signals. The directional roadside transceiver antennas may also transmit predominantly in the direction of the zone of interest, reducing the chances that a stray in-vehicle transceiver may pick up its signal and respond back.
• In various embodiments, the roadside devices may be synchronized precisely and measure the relative or absolute arrival time of the in-vehicle device signals and determine the location of the in-vehicle device by triangulation. The time of arrival of the leading or trailing edge of the next or subsequent in-vehicle beacon can be measured and reported by the roadside devices, or may be measured by two receiving circuits and antennas on the same roadside device. The two receiving circuits can be in the same or in nearby enclosures and are coupled electrically or wirelessly.
• In various embodiments, a marker pulse from the broad spectrum radar can be used for wake-up or for location determination purposes.
• The communication between the roadside and in-vehicle devices may be standards based or may use a proprietary protocol or another protocol may be used. The protocol may be further customized to keep the beacon burst very short, for example, less than one or a few milliseconds or even less than a microsecond. The beacon burst may or may not contain all the information needed for the identification. A subsequent time interval after the beacon burst may be used the two devices to signal its need to communicate further and establish two way communications to get the identification information or for authentication or security purposes.
