In one embodiment of the present application, thewireless transmitting unit 12 includes: any one of an ultrasonic transmitter, a radio frequency transmitting circuit and a frequency modulation transmitter; accordingly, the wireless receiving unit 13 includes: any one of an ultrasonic receiver, a radio frequency receiving circuit, and a FM receiver.

In the above embodiment, thewireless transmitting unit 12 may simultaneously include an ultrasonic transmitter, a radio frequency transmitting circuit, and a frequency modulation transmitter, and the wireless receiving unit 13 may simultaneously include an ultrasonic receiver, a radio frequency receiving circuit, and a frequency modulation receiver, and the ultrasonic waves or electromagnetic waves transmitted by the different types ofwireless transmitting units 12 are used to represent the different driving prompt signals. For example, the ultrasonic signal transmitted by the ultrasonic transmitter and the ultrasonic receiver is used for representing the green light traffic prompting signal; the electromagnetic waves transmitted by the radio frequency transmitting circuit and the radio frequency receiving circuit are used for representing steering prompt signals, and a left steering prompt signal and a right steering prompt signal are represented by channels with different preset frequency bands; and the electromagnetic wave signals transmitted by the frequency modulation transmitter and the frequency modulation receiver are used for representing the fault parking prompt signal.

For example, thewireless transmitting unit 12 is an ultrasonic transmitter, which may be an ultrasonic transmitting circuit formed by a 555 flip-flop chip, and as shown in fig. 3A, the ultrasonic transmitting circuit outputs 40KHz oscillation pulses from a pin of the 555 flip-flop chip to drive the ultrasonic sensor to work, so as to generate pulses, and builds a high-frequency ultrasonic wave on the basis of the pulses, so that the ultrasonic wave transmits a 40KHz ultrasonic signal. The pulse frequency is high to the extent that ultrasound can be generated with a vibrator as shown in the figure. The 8 pins of the 555 flip-flop chip are input ends of working voltage of the integrated circuit, and the voltage is 5-18V.

Accordingly, the ultrasonic receiver receives an ultrasonic signal of a preset operating frequency (e.g., 40KHz) through the receiver to receive the ultrasonic signal.

In addition, thewireless transmitting unit 12 can also be, for example, an ultrasonic transmitting circuit composed of discrete components, and the T/R-40-16 composed of discrete components can transmit a string of ultrasonic signals of 40 kHz.

For another example, thewireless transmission unit 12 may also use nRF24L01 based radio frequency transmission circuitry or FM frequency modulation wireless transmission circuitry, or the like. As shown in fig. 3B, the radio frequency transmitting circuit of thewireless transmitting unit 12 is, for example, a 433MHz wireless transmitting module, the operating frequency is 315MHz/433MHz, the communication mode is amplitude modulation AM, the SAW frequency stabilization is performed by using a sound surface resonator, the frequency stability is very high, and is ± 75kHz, when the ambient temperature changes from-25 to +85 degrees, the frequency drift is only 3 ppm/degree, the transmitting power is less than or equal to 500mW, the quiescent current is less than or equal to 0.1 μ a, the transmitting current is 3 to 50mA, the operating voltage isDC 3 to 12V, the communication is supported by IPV6, the number of interference sources is small, the communication distance is long, and the actually measured visible distance is supported by 4 to 6K.

The rf receiving circuit of the wireless receiving circuit 13 may be a 433MHz wireless receiving module, as shown in fig. 3C, which is not described herein again.

In an embodiment of the present application, the wireless transmitting unit and the wireless receiving unit characterize the different driving prompt signals by presetting different frequency bands or wave bands.

For example, the 433MHz radio transceiver module has an operating frequency of 315MHz or 433MHz, and the commonly open domestic radio frequencies include: 315MHz, 433MHz, 868MHz and 915 MHz. Corresponding to the 433MHz frequency, the domestic open frequency band is 433.05-434.79MHz, preset division is carried out in the frequency band through a certain division protocol, for example, the divided frequency deviation can be 20khz, 30khz, 40khz and the like, a plurality of channels can be formed after division, and different channels can transmit signals in parallel.

Each channel can correspondingly transmit different driving prompt signals. For example, 433.1MHz is used to transmit a signal indicating green light passing, 433.2MHz is used to transmit a signal indicating left turn, 433.3MHz is used to transmit a signal indicating right turn, and 433.4MHz is used to transmit a signal indicating failed stop.

In an embodiment of the present application, the wireless transmitting unit and the wireless receiving unit set a certain strength according to a frequency band or a waveband of the driving prompt signal, where the characteristics of the wireless transmission are different, so as to control a normal transmission distance or a normal transmission range between the wireless transmitting unit and the wireless receiving unit.

For example, in a usage scenario corresponding to a green light passage warning signal and a turn warning signal, the actual transmission distance may be kept within 50 meters of the own driving warning device, and in a usage scenario corresponding to a trouble stop warning signal, the actual transmission distance may be kept within 200 meters of the own driving warning device.

Within a smaller range, the fewer vehicles receiving the driving prompting signals are, the more accurate the driving prompting signals are. For example, in a usage scenario corresponding to a green light traffic prompt signal, only the preceding vehicle needs to receive the green light traffic prompt signal.

It should be noted that the driving prompting device can send the driving prompting signal to a plurality of nearby vehicles, and the signal sending range is determined by the transmission characteristics of the wireless transmitting unit and the wireless receiving units of other vehicles. In addition, the driving prompting device can be arranged in an automobile, and a prompting unit for sounding, lighting or vibrating is arranged in a closed space of the automobile to transmit a prompting signal, so that noise pollution to the external environment is avoided; the prompting signal is transmitted by a silent prompting unit such as light emitting or vibration, and the noise pollution to the external environment is avoided.

It should be noted that, when the car horn is used, although it may be only intended to remind the driver of the preceding car, the drivers of the surrounding cars will also hear the car horn, but the driver with the problem (such as the driver who is distracted or makes a call but does not start the car at the green light) can be reminded in time. The application the driving prompting device can also realize that the driver who has problems can be reminded in time, although other drivers who do not have problems can also accept the driving prompting signal sent by the driving prompting device, the driving prompting device does not influence the drivers, and the driver who has the behaviors can be reminded in time. Therefore, this application driving suggestion device have the practicality.

In one embodiment, the driving prompting device is applied to a vehicle and used for sending driving prompting signals to other vehicles and/or receiving driving prompting signals from other vehicles. It should be noted that, each unit of the driving prompting device can be separately arranged at different positions in the vehicle, and each unit can also be collectively arranged at a certain position in the vehicle, which is not limited in the present application.

For the convenience of understanding of those skilled in the art, the application scenario diagram of the driving prompting device in an embodiment of the present application shown in fig. 2 is further explained and explained.

In an embodiment of the present application, the promptingunit 14 presets a corresponding prompting action according to different driving prompting signals; the promptingunit 14 comprises any one or a combination of a sounding unit, a light-emitting unit, a vibration unit and a display unit; wherein, the sound production unit comprises a loudspeaker and/or a buzzer; the light-emitting unit comprises an indicator light; the vibration unit comprises a vibrator; the display unit includes a display screen.

In one embodiment, the prompting unit includes, but is not limited to, a sound unit, a light unit, a vibration unit, or a display unit. The sound emitting unit is, for example, a speaker or a buzzer or the like; the light emitting unit is, for example, an indicator lamp; the vibration unit is, for example, a vibrator; the display unit is, for example, a display screen.

It should be understood that different cueing units perform different cueing actions, for example: the indicator light gives an indication by lighting and turning off, the loudspeaker gives a prompt by playing voice, the buzzer gives a prompt by buzzing, the vibrator gives a prompt by vibrating, and the display screen gives a prompt by displaying patterns and/or characters and the like.

It should be emphasized that thesignal triggering unit 11 corresponding to the green light passing prompt signal in the present application is preferably a speaker or a buzzer, and a driver of a front vehicle can hear the same "dripping" sound as a traditional horn, but can not hear people outside the vehicle; thesignal triggering unit 11 corresponding to the fault parking prompt signal is preferably a loudspeaker or a buzzer or a vibrator, and is preferably distinguished from the sound corresponding to the green light traffic prompt signal.

In addition, in order to simplify the prompt action of the driver to know theprompt unit 14, theprompt unit 14 corresponding to the left steering prompt signal, the right steering prompt signal, and the parking failure prompt signal may also be a voice playing device or a display screen, so as to accurately express the corresponding driving prompt signal by voice or text.

In one embodiment, the prompting unit presets corresponding different prompting actions according to different prompting purposes; the prompting purpose includes but is not limited to a green light passing prompt, a steering prompt, or a fault parking prompt, etc. The green light passing prompt is mainly used for prompting vehicles which meet the green light but do not pass, such as a vehicle owner sleeping, in a call, playing electronic products or other situations which are not focused on driving; the steering prompt is mainly used for prompting other vehicles that the vehicle is in a steering state; the fault parking prompt is mainly used for prompting other vehicles to be in fault parking so as to avoid secondary collision accidents, particularly on high-speed roads, the failure that the owners of the other vehicles do not react in time to bump the fault vehicles often occurs, so that the driving prompt device of the embodiment effectively avoids secondary collision through wireless transmission driving prompt and promotes driving safety.

Specifically, it is considered that a single prompt form corresponding to a plurality of prompt purposes may cause troubles to personnel in the signal receiving vehicle, and prompt contents cannot be identified effectively. Therefore, the embodiment presets the corresponding prompting action for the prompting unit according to different prompting purposes, so that the signal receiver can quickly distinguish the signal prompting purpose and respond to the prompting signal more effectively.

The different prompting actions can be different prompting actions made by different types of prompting units, or different prompting actions made by the same type of prompting unit. For example: presetting buzzer long-time sounding as a prompt for a green light passing prompt, presetting high-frequency vibration for a fault parking prompt and the like; for another example: the low-frequency buzzer is preset for the green light passing prompt as the prompt, the high-frequency buzzer is preset for the fault parking prompt, and the like, which is not limited in this embodiment.

Preferably, the application is directed to a green light passage prompting signal which may correspond to a prompting action such as a speaker and/or buzzer which sounds a "beep".

Preferably, the fault parking prompt signal and the steering prompt signal can be used for making a prompt action corresponding to a loudspeaker and/or a buzzer which gives a prompt sound of 'the accessory vehicle has fault parking/steering', or the display unit displays a character of 'the accessory vehicle has fault parking/steering' to make a prompt action.

In an embodiment, the driving prompting device is further provided with a power supply unit, including but not limited to: button cell, power cord, Micro usb interface, Type-C interface, 30-pin charge interface, and light common charging methods such as interface.

For example, asignal trigger unit 11 for the driver to operate may be disposed on the steering wheel, and asignal trigger unit 11 for the passenger in the passenger seat to operate may be disposed on the passenger seat or the rear seat, so that the passenger in the rear seat or the passenger seat can assist the driver to send a driving prompt in a more timely manner.

Thesignal trigger unit 11 for the assistant driver seat can be specifically arranged at the positions of a vehicle door, below the seat, above the seat and the like, and can also be arranged near a footwell so as to operate the signal trigger unit by using the feet of a human body; thesignal triggering unit 11 for the rear seat can be specifically disposed at a vehicle door, a position below the seat, a position above the seat, or a position behind the front seat, and the like, which is not limited in this embodiment.

In one embodiment, the driving prompting device includes a plurality of promptingunits 14 respectively disposed in the front space and/or the rear compartment of the vehicle to transmit driving prompting signals to the front and/or rear occupants. Considering that the driving prompt sent by the promptingunit 14 may not be effectively transmitted to the driver, for example, the prompting volume of the speaker is not large enough, or the prompting light brightness of the indicator light is not enough, the vibration prompt of the vibrator is not strong enough, etc. Therefore, in the technical solution of the present embodiment, the plurality ofprompt units 14 are respectively disposed in the front space and/or the rear space of the vehicle, so that the rear passenger or the passenger in the front passenger can assist the driver to grasp the driving prompt more timely.

In an embodiment, thesignal triggering unit 11 is a lock-free signal triggering unit, which triggers to generate a driving prompting signal after being pressed, and stops generating the driving prompting signal after being released from the pressing, so that the device is convenient to use and has low cost. The unlocking signal trigger unit is, for example, an unlocking button switch, and the button switch generates a prompt signal when a user presses the unlocking button switch, and the button switch does not generate the prompt signal when the user releases the unlocking button switch.

In an embodiment, thesignal triggering unit 11 is a self-locking signal triggering unit, which triggers to generate a driving prompting signal after being pressed, and generates the driving prompting signal after being released from the pressing, until the driving prompting signal is stopped being generated after being pressed again. The self-locking signal trigger unit is, for example, a self-locking button switch, when a user presses the self-locking button switch, the coil of the contactor is continuously electrified, so that the state of the contact point is kept, the button switch generates a prompt signal, the button switch still generates the prompt signal when the user releases the self-locking button switch, and the generation of the prompt signal is stopped when the user presses the self-locking button switch again. The self-locking signal trigger unit can continuously generate driving prompt signals without continuous pressing of a user, is suitable for emergency situations such as emergency stop, emergency lane change or emergency overtaking and is also suitable for relatively slow vehicle adjustment processes such as backing and turning around.
