Specifically, the vehicle control system is applied to a new energy vehicle, that is, to a vehicle including the battery module 300 and the fuel cell module 200, and the battery module 300 and the fuel cell module 200 are each capable of individually supplying power (a first power supply and a second power supply) to the vehicle. When the battery module 300 malfunctions, for example: when the available electric quantity of the storage battery is lower than a preset threshold value, which causes that the automobile cannot run normally, a user generates a mode conversion instruction by pressing the first switch module 400. The control module 100 receives the mode switching command and controls the battery module 300 to be turned off according to the mode switching command. The fuel cell module 200 includes a plurality of switching valves and components, and the self-test unit 210 is configured to check the on/off state of the low voltage power supply of each switching valve and the power supply state of each component. When the self-checking result of the fuel cell module 200 is normal, the control module 100 controls the fuel cell module 200 to be turned on according to the mode switching instruction and controls the fuel cell module 200 to output 20KW of power, so that the vehicle is restarted according to the second power supply provided by the fuel cell module 200 and travels according to the 20KW of power. It is understood that the output power of the fuel cell module 200 may be adaptively adjusted according to actual conditions.
The automobile control system provided by the embodiment of the application controls the storage battery module 300 to be turned off through the control module 100, and controls the fuel cell module 200 to be turned on, so that when the storage battery module 300 breaks down, an automobile can be restarted according to the second power supply provided by the fuel cell module 200, and the hidden danger of the public transportation safety caused by the stop operation of the whole automobile when the storage battery module 300 goes wrong is avoided.
Referring to fig. 2, in some embodiments, the vehicle control system further comprises: the inversion module 500. The inverter module 500 is connected to the control module 100 and the fuel cell module 200, respectively, wherein the control module 100 is further configured to control the inverter module 500 to perform an inverter operation according to the mode switching command. Specifically, when the control module 100 receives the mode switching command, the control module 100 performs an inversion operation on the voltage, for example: the DCDC inverter is started according to the mode conversion command so that the 24V voltage is converted into the 400V voltage to satisfy the turn-on voltage condition of the fuel cell module 200, thereby achieving the turn-on of the fuel cell module 200. It can be understood that, when the control module 100 controls the inverter module 500 to perform the inverter operation, the control module 100 simultaneously turns off the low voltage system of the vehicle to ensure complete turn-off of the battery module 300.
In some embodiments, the vehicle control system further comprises: a second switching module 600 and a capacitance module 700. The second switch module 600 is connected to the control module 100 and configured to generate a discharge command; the capacitance module 700 is connected to the control module 100. The control module 100 is further configured to control the capacitor module 700 to perform a discharging operation according to the discharging instruction.

When the vehicle is restarted according to the second power supply provided by the fuel cell module 200, the user may drive the vehicle to a maintenance station to check the battery module 300. After the vehicle arrives at the maintenance station, the user generates a discharge instruction by pressing the second switch module 600, and the control module 100 performs a discharge operation on the capacitor module 700 according to the discharge instruction, that is, converts the remaining electric energy of the super capacitor into heat energy, so as to ensure that the fuel cell system is completely turned off, and the vehicle can be normally powered off and stopped.
In some embodiments, the first switch module includes a first switch and the second switch module includes a second switch. Wherein, first switch and second switch are the rocker switch. Specifically, the first switch and the second switch are rocker switches with a self-locking function so as to prevent misoperation of a user.
Referring to fig. 3, an embodiment of the present application provides an automobile control method, which is applied to an automobile control system as described in any of the above embodiments. The automobile control method comprises the following steps: s100, generating a mode conversion instruction by a first switch module; s200, the control module performs shutdown operation on the storage battery module according to the mode conversion instruction; s300, carrying out self-checking operation on the fuel cell module, and obtaining a self-checking result; and S400, the control module controls the fuel cell module to be started according to the self-detection result and the mode conversion instruction.
One embodiment of the steps S100 to S400 is as follows: the automobile control system applied by the automobile control method is arranged on a new energy automobile, namely the automobile comprising a storage battery module and a fuel cell module, and the storage battery module and the fuel cell module can independently provide power supplies (a first power supply and a second power supply) for the automobile. When a battery module fails, for example: when the available electric quantity of the storage battery module is lower than a preset threshold value and the automobile cannot run normally, a user presses the first switch module to generate a mode conversion instruction. The control module receives the mode conversion instruction and controls the storage battery module to be switched off according to the mode conversion instruction. The fuel cell module comprises a plurality of switch valves and components, and the self-checking unit is used for checking the on-off function of the low-voltage power supply of each switch valve and the power supply state of each component. When the self-checking result of the fuel cell module is normal, the control module controls the fuel cell module to be started according to the mode switching instruction, and controls the fuel cell module to output 20KW power, so that the automobile is restarted according to a second power supply provided by the fuel cell module, and runs according to the 20KW power. It will be appreciated that the output power of the fuel cell module may be adapted to the actual conditions.
In some embodiments, step S200 comprises: the control module turns off a low-voltage system of the automobile according to the mode switching instruction. Step S400 includes: and if the self-checking of the fuel cell system is normal, the control module executes control of the inversion module to perform inversion operation according to the mode conversion. Specifically, when the control module receives the mode switching instruction and the inspection result of the self-inspection unit on the fuel cell module is normal, the control module performs an inversion operation on the voltage, for example: the DCDC inverter is started according to the mode conversion command so that the 24V voltage is converted into the 400V voltage to satisfy the turn-on voltage condition of the fuel cell module. When the control module controls the inversion module to perform inversion operation, the control module simultaneously cuts off a low-voltage system of the automobile so as to ensure complete turn-off of the storage battery module.
Referring to fig. 4, in some embodiments, the vehicle control method further includes the steps of: s500, generating a discharging instruction by the second switch module; s600, the control module controls the capacitor module to perform discharging operation according to the discharging instruction.
One embodiment of the steps S500 to S600 is as follows: the capacitor module includes a super capacitor for providing an auxiliary electrical signal to the fuel cell system. When the vehicle is restarted according to the second power supply provided by the fuel cell system, the user can drive the vehicle to a maintenance station to check the battery module. After the automobile arrives at the maintenance station, a user presses the second switch module to generate a discharging instruction, and the control module performs discharging operation on the capacitor module according to the discharging instruction so as to ensure that the fuel cell system is completely turned off, even if the automobile can be normally powered off and stopped.
In one specific embodiment, during the driving of the vehicle, when the battery module fails, for example: when the available electric quantity of the storage battery module is lower than a preset threshold value, and the automobile cannot run normally, a user turns OFF a low-voltage system of the whole automobile by dialing the key to an OFF gear, and turns ON the key again after a certain time (for example, 30S) so as to restart the low-voltage system of the whole automobile, thereby ensuring the complete turn-OFF and turn-ON of the low-voltage system of the whole automobile. The user presses the rocker switch (first switch) of the "limp home" to generate a mode switching command, according to which the control module starts the DCDC inverter to switch the voltage from 24V to the high voltage required for the fuel cell module to turn on, and disconnects the low voltage system of the car. The fuel cell module carries out self-checking operation, and after the self-checking is completed, 20KW rated power is output according to the control of the control module, and the automobile restarts to run according to a second power supply provided by the fuel cell module. After the automobile is driven to a maintenance station, a user presses a discharge switch (a second switch) to discharge the super capacitor so as to convert the electric energy of the super capacitor into heat energy, thereby realizing the complete discharge of the fuel cell system, and after the discharge is finished, the rocker switches of the discharge switch and the limp mode are closed so as to finish the normal power-off parking.
In some examples, the present application provides an automobile control device including an automobile control system as described in any one of the above embodiments.
According to the automobile control system, the method and the equipment, the storage battery module is turned off when the storage battery module breaks down, the fuel battery module is started, normal running of an automobile is guaranteed, and hidden dangers brought to public traffic safety when the whole automobile stops running when the storage battery fails are avoided.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. Furthermore, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
