Detailed Description
The present application will be described and illustrated with reference to the accompanying drawings and examples for a clearer understanding of the objects, technical solutions and advantages of the present application.
In this embodiment, a hybrid ATV 100 is provided, which includes a body 10, wheels 20, and a powertrain 30, as shown in FIG. 1. The wheels include a front wheel 21 provided on the front side of the vehicle body 10 and a rear wheel 22 provided on the rear side of the vehicle body 10. The power system 30 includes an engine 31, a power battery 32, and a drive motor 33, the power system 30 being provided on the vehicle body 10 for powering the motorcycle, at least one of the front wheels 21 and the rear wheels 22 being connected to the power system 30; the power battery 32 is connected to the driving motor 33, and is used for providing electric energy to the driving motor 33, and the engine 31 is used for charging the power battery 32. The hybrid power all-terrain vehicle 100 can be a serial hybrid power all-terrain vehicle, the engine directly drives the generator to generate power, the generated electric energy is transmitted to the power battery through the controller, the power battery is transmitted to the motor to be converted into kinetic energy, and finally the all-terrain vehicle is driven through the speed change mechanism; hybrid ATV 100 may also be a parallel hybrid ATV having two sets of drive systems: the engine driving system and the motor driving system can be coordinated to work simultaneously or independently to drive the all-terrain vehicle.
Hybrid all-terrain vehicle 100 also includes battery management system 40 and control module 50. The battery management system 40 is provided on the vehicle body 10, detects the amount of power of the power battery 32 when the ATV engine is not started, and transmits a power replenishment request when it is detected that the amount of power of the power battery 32 is lower than a first power threshold. The control module 50 is disposed on the vehicle body 10 and connected to the battery management system 40, and is configured to receive a power replenishment request sent by the battery management system 40, and when the all-terrain vehicle meets a power replenishment condition, the control module 50 starts the engine 31 to charge the power battery 32.
It should be noted that, the Battery Management System (BMS) 40 can accurately estimate the state of charge of the power Battery 32, calculate the remaining capacity of the power Battery 32, ensure that the remaining capacity is maintained within a reasonable range, and dynamically monitor the operating state of the power Battery 32, and collect the terminal voltage and temperature, the charge-discharge current and the Battery pack voltage of the Battery in real time during the charge-discharge process of the Battery, so as to prevent the Battery from being damaged due to overcharge or overdischarge. The battery management system 40 is capable of detecting the charge of the power battery 32 when the hybrid atv 100 is in an inactive state, parked for a long period of time, and the battery management system 40 sends a power replenishment request to the control module 50 when it detects that the charge of the power battery 32 is below a first charge threshold, for example, when the charge is below 30%. When the power battery 32 is low in electric quantity and the power supplementing condition is met, the control module 50 timely starts the engine 31 to work so as to supplement power for the power battery 32, so that the situation that the power battery 32 is deficient in power, which may occur under the condition that the hybrid all-terrain vehicle 100 is parked for a long time, is avoided, the hybrid all-terrain vehicle 100 can be started normally, and meanwhile the service life of the power battery 32 is not influenced.
In some of these embodiments, the power up condition comprises: the remaining oil level of the hybrid all-terrain vehicle 100 is higher than the oil level threshold, the power battery 32 is not failed, the engine 31 is not failed, the high-voltage interlocking is not failed, the high-voltage wire harness is not leaked, and the like, and only when the power supplementing condition is met, the control module 50 starts the engine 31 to charge the power battery 32, so that the safety of the all-terrain vehicle is improved when the power battery 32 is supplemented with power. When the power supplementing condition is not met, the control module 50 controls the all-terrain vehicle to sleep, namely, all controllers on the all-terrain vehicle enter a low-power consumption state as a whole, so that the condition of overlarge low-voltage power consumption can be avoided.
The power battery fault includes voltage, insulation and other anomalies, such as water inlet of a battery box, leakage of a battery core and other conditions, and does not include damage of a temperature sensor and other conditions. The engine failure includes a failure of the injector control circuit, a failure of the intake pressure sensor, etc., and does not include a failure of the vehicle speed sensor, etc.
In some of these embodiments, hybrid ATV 100 includes a communication module 60, as shown in FIG. 2, where communication module 60 is coupled to control module 50 for receiving requests sent by control module 50, and where communication module 60 is also capable of communicating with ATV user's mobile terminal 70. When the power-up condition is satisfied, the control module 50 sends a power-up activation request to the communication module 60, and the communication module 60 sends the power-up activation request to the mobile terminal 70; the communication module 60 is capable of receiving an instruction from the mobile terminal 70 regarding whether the user of the ATV is permitted to supplement electricity, and transmitting the instruction to the control module 50.
The communication module 60 may be a 4G networking module, or may be a remote communication module (TELEMATICS BOX, abbreviated as T-BOX) 61 integrated with the 4G networking module. As shown in fig. 3, the T-BOX61 is connected to the CAN bus through an interface, collects data through the CAN bus, mainly collects and analyzes information of the battery management system 40 and other controllers on the all-terrain vehicle, and after collecting the information, the T-BOX61 stores the collected real-time data in an internal storage medium at a time interval of not more than 30 seconds at maximum. In addition, the T-BOX61 may communicate with a mobile terminal 70, such as a cell phone, and the T-BOX61 uploads the acquired signals to a cloud platform, which transmits the data to the cell phone.
Further, when the power-up condition is met, the control module 50 sends a power-up activation request to the T-BOX61, the T-BOX61 sends the power-up activation request to the mobile phone APP of the user, the user confirms on the mobile phone APP whether to allow power-up, the mobile phone sends an instruction to the T-BOX61 about whether to allow power-up, and the T-BOX61 sends the instruction to the control module 50, so that remote communication and remote control are realized, and the control module 50 signs user consent before starting the engine 31 to charge the power battery 32.
Alternatively, if the communication module 60 receives the command for allowing power replenishment from the mobile terminal 70, the control module 50 starts the engine 31 for charging the power battery 32. If the communication module 60 receives the power supply prohibition instruction sent by the mobile terminal 70, the control module 50 controls the all-terrain vehicle to sleep, i.e. each network node of the CAN network to sleep, so that the control module 50 CAN be prevented from frequently sending power supply requests to the communication module 60, and thus, the user CAN be prevented from frequently receiving the power supply request information at the mobile terminal 70.
In some embodiments, if the battery management system 40 detects that the power of the power battery 32 is above the second power threshold while the power battery 32 is being charged, for example, when the power of the power battery 32 is above 80%, the control module 50 controls the engine 31 to stop charging the power battery 32 and controls the ATV to sleep, i.e., the controllers on the ATV enter a low power state.
Further, if the battery management system 40 detects that the power level of the power battery 32 is higher than the second power level threshold, the communication module 60 sends a charge completion notification to the mobile terminal 70, so that the user knows the state of the hybrid all-terrain vehicle 100 through the mobile terminal 70.
In some embodiments, the control module 50 includes a vehicle controller 51 and a vehicle body controller 52, after receiving the command for allowing power replenishment, the communication module 60 sends the command for allowing power replenishment to the vehicle controller 51 and the vehicle body controller 52, respectively, the vehicle controller 51 controls the high-voltage circuit where the engine 31 and the power battery 32 are located to be closed in response to the command for allowing power replenishment, and the vehicle body controller 52 controls the KL15 to be powered on in response to the command for allowing power replenishment. When the power battery 32 is charged, if the battery management system 40 detects that the electric quantity of the power battery 32 is higher than the second electric quantity threshold value, the whole vehicle controller 51 controls the high-voltage loop where the engine 31 and the power battery 32 are located to be disconnected, and the vehicle body controller 52 controls the KL15 to be powered down. KL15 is a hard wire for transmitting high and low levels, and is connected with a chip pin to transmit an engine ignition signal.
It should be noted that, the vehicle controller 51 is used for implementing energy management and control of the power system 30, and is a control center of the hybrid all-terrain vehicle 100, and functions of the vehicle controller 51 further include: maintenance and management of the CAN network, diagnosis and processing of faults, vehicle state monitoring and the like. The vehicle body controller 52 is an electronic control unit for controlling the vehicle body electrical system, and may be connected to other controllers through a CAN bus, and functions of the vehicle body controller 52 include: the vehicle body controller 52 also controls the power up and power down of the KL15, controlling power windows, air conditioners, headlamps, turn lamps, anti-theft lock systems, and the like.
In some of these embodiments, the control module 50 sends a feedback signal to the battery management system 40 after receiving the power up request from the battery management system 40, and the battery management system 40 does not wake up the ATV before the KL15 is powered up. Specifically, after the control module 50 receives the power-up request and before the KL15 is powered up, there is a case that the all-terrain vehicle does not meet at least one of the power-up condition and the user sends the command for prohibiting the power-up, and by setting the battery management system 40 not to wake up the all-terrain vehicle before the KL15 is powered up, the hybrid all-terrain vehicle 100 does not cause excessive low-voltage power consumption due to frequent wake-up.
Optionally, hybrid ATV 100 includes a human-machine interface that receives an on command sent by an ATV user, and battery management system 40 turns on an automatic wake-up function in response to the on command and feeds back an on state of the automatic wake-up function to the user; or when the communication module 60 receives a wake-up instruction sent by the mobile terminal 70, the battery management system 40 is woken up and detects the power of the power battery 32.
It should be noted that, the man-machine interaction interface may be a touch screen of the hybrid all-terrain vehicle 100, or may be a key on the vehicle body 10, and the user turns on the battery management system 40 to wake up the function automatically through the touch screen or the key. Alternatively, the user may initiate the automatic wake-up function of the battery management system 40 by means of remote communication, for example on the mobile phone APP.
The user may send a wake-up command to the hybrid all-terrain vehicle 100 via the mobile terminal 70 when the vehicle is not used for a long time, and the communication module 60 of the all-terrain vehicle wakes up the battery management system 40 and detects the electric quantity of the power battery 32 after receiving the wake-up command. Therefore, the user can set the automatic wake-up function of the battery management system 40 according to the own demand, and can wake up the battery management system 40 at any time according to the own demand to detect the electric quantity of the power battery 32.
