With the electrical architecture in embodiment 2 described above, the vehicle has a remote control mode, an automatic driving mode, a charging mode, and a remote control mode.
Remote control mode:
after a first switch 16 positioned on the vehicle is pressed, the whole vehicle controller 14 is started, the whole vehicle controller 14 drives a main relay 17 to be closed through a pin 1, and an electronic parking system 8 (EPB), a wire control and power unit 9 (IBS), a front steering controller 7, a rear steering controller 8 (EPS), a motor controller 11, a remote control receiving module 13 and the like on the chassis are activated to obtain 12v voltage; at the same time the BMS5 and the chassis DC/DC voltage converter 1 are activated and the DC contactor 18 and the pre-charge relay 20 are also closed. After the BMS5 is started, the internal main negative contactor is closed, and the closed normal state is fed back to the whole vehicle controller 14 through the CAN network; at the same time the motor controller 11 starts pre-charging and the voltage gradually rises. When the whole vehicle controller 14 detects that the BMS closes the main negative contactor normally and the inverter voltage is greater than 90% of the battery voltage, the main positive contactor 20 inside the high voltage distribution box 6 (PDU) is closed, and the whole vehicle high voltage circuit is turned on to complete power-up. At this time, the chassis DC/DC voltage converter 1 starts to output to supply power to each electric appliance. The vehicle controller 14 controls the operation of the vehicle through the instruction of the remote control receiving module 13.
Automatic driving mode:
when the vehicle is operating in the remote control mode, the automatic driving state can be entered by turning on the body second switch 42 (SW 4) or a mode changeover switch on the remote control. After receiving the hard wire signal of SW4 or the mode switching signal of the remote control receiver, the vehicle controller 14 activates the upper-mounted DC/DC voltage converter through the pin 81, and enters the automatic driving mode after the upper-mounted electric component is started. The whole vehicle controller 14 receives an instruction from the unmanned area controller 25 (ACU) to control the vehicle to run in the automatic driving mode. When the vehicle is in the automatic driving mode, the mode switching button at the remote controller end can return to the remote control mode, the whole vehicle controller 14 does not disconnect the enabling of the upper-mounted DC/DC voltage converter any more, repeated starting of upper-mounted electric devices is avoided, and the automatic driving and the quick switching of the remote control mode are also facilitated. Pressing the second switch 42 (SW 4) on the vehicle body turns off the output of the on-board DC/DC voltage converter and returns to remote control mode.
Charging mode:
the vehicle must be in a powered down state before entering the charging mode. Clicking the first switch 16 allows the entire vehicle to be powered down. After the charging gun is inserted into the charging seat 22, the vehicle-mounted charger 23 is connected to 220v for starting, the 2H pin of the vehicle-mounted charger 23 wakes up the BMS, and the BMS and the charging gun are connected and confirmed and power confirmed through cc and cp pins. The BMS closes the internal master negative contactor and closes the charging contactor 21 in the high voltage distribution box 6 (PDU) through pin No. 5, and the on-board charger 23 closes the DC contactor 18 in the PDU through pin No. 2H and enables the chassis DC/DC voltage converter. At this time, the 72V high voltage main battery and the 12V storage battery both start to charge, and the upper DC/DC voltage converter is not started.
Emergency stop mode:
pressing the emergency brake switch 24 on the vehicle when the vehicle is in the automatic driving or remote control mode can cut off the 12v power supply of the motor controller 11 so as to cut off the power of the whole vehicle, and meanwhile, the hard wire signal obtained by the whole vehicle controller 14 for emergency stop can control the wire control brake unit 9 to carry out emergency stop. The emergency brake switch 24 is pulled out, the power supply to the motor controller 11 is restored, and the emergency stop signal is canceled. The power can be cut off through an emergency stop switch at the remote controller end, and the vehicle can be stopped.
In summary, the invention innovates the upper electric component of the sensor part and the chassis electric component of the general part on the receiving of the power supply, and connects the chassis electric component with the power supply module through the chassis DC/DC voltage converter to realize the power receiving of the chassis electric component; the electric components are connected with the power module through the upper DC/DC voltage converter, so that the power receiving of the upper electric components is realized, the upper electric components can be purposefully closed in the running process of the vehicle, the unnecessary operation and energy waste of the upper electric components are reduced, the electric quantity of a battery is saved, and the cruising ability of the vehicle is improved. In addition, the storage battery is connected with the steering controller, and when the chassis DC/DC voltage converter fails, the steering controller can still continuously work for a period of time by depending on the electric quantity of the storage battery, so that the running safety of a vehicle is improved. Furthermore, when the battery is charged, the battery can be charged through the chassis DC/DC voltage converter, so that the health of the battery is maintained, and the service life of the battery is prolonged.
