1. Technical Field

[0001] This case belongs to the field of mobile safety travel, energy conservation and emission reduction, low carbon and environmental protection. It is an optimization and upgrade of the existing pure electric vehicle and hybrid vehicle power drive safety technology solutions, making pure electric vehicles and hybrid vehicles safer and more reliable, and the optimization and upgrade costs are low. It can remedy the driver's operating errors during vehicle use and reduce the risk and harm of accidents caused by driver operating errors. 2. Background Technology

[0002] When humans operate equipment, such as driving a car, there will always be mistakes. If the driver presses the accelerator pedal as the brake pedal, the consequences are serious, that is, the severity is high; the panicked driver is self-aware of the low possibility of misoperation, that is, the detectability is low; although the probability of driver misoperation is low, the entire society has a large vehicle base and the vehicle product life cycle is long, so driver human operation errors are inevitable. In view of this, for the needs of vehicle passive safety, the vehicle should tolerate the driver's operating errors, and a fool-proof design should be made. The vehicle should have remedial measures after the driver's misoperation to reduce vehicle traffic risks and hazards. In response to this problem, this case proposes a vehicle power cut-off remedial design method and device for the driver to mistakenly press the accelerator pedal as the brake pedal. This technical solution is simple, safe, reliable, and has low optimization and upgrade costs. III. Summary of the invention

[0003] The purpose of the present invention is to provide a simple, safe, reliable and optimized passive safety device with low upgrade cost, a vehicle power cut-off remedy design method and device when the driver mistakenly steps on the accelerator pedal as the brake pedal.

[0004] The present invention relates to a method and device for remedial power cutoff of a vehicle when a driver mistakenly steps on an accelerator pedal as a brake pedal. The method and device comprise a low-voltage power supply network 1 of the vehicle, a positive wire 2, a negative wire 3, a mechanical control normally closed switch 4, a positive wire 6, a negative wire 5, and a drive device controller 7. The positive output terminal of the low-voltage power supply network 1 of the vehicle is connected to the positive input terminal of the mechanical control normally closed switch 4 by the positive wire 2, the negative output terminal of the low-voltage power supply network 1 of the vehicle is connected to the negative input terminal of the mechanical control normally closed switch 4 by the negative wire 3, the positive output terminal of the mechanical control normally closed switch 4 is connected to the positive input terminal of the low-voltage power supply of the drive device controller 7 by the positive wire 6, the negative output terminal of the mechanical control normally closed switch 4 is connected to the negative input terminal of the low-voltage power supply of the drive device controller 7 by the negative wire 5, the mechanical control normally closed switch 4 is in an open state when pressed, and in a normally closed state when reset, the mechanical control normally closed switch 4 should be easily identifiable and eye-catching, such as red, and placed at a position where the driver can reach out and press, such as near the vehicle's double flash warning switch.

[0005] The invention can realize the function of cutting off the power output of the whole vehicle in panic after the driver accidentally steps on the accelerator pedal during operation. The operation is simple, safe, reliable and the optimization and upgrading cost is low. IV. Description of the drawings

[0007] This case is a design method and device for cutting off the power of the whole vehicle when the driver mistakenly steps on the accelerator pedal instead of the brake pedal. The device can cut off the power output of the whole vehicle in a panic after the driver mistakenly steps on the accelerator pedal.

[0008] A method and device for remedial power cutoff of a vehicle when a driver mistakenly steps on an accelerator pedal as a brake pedal, wherein the positive output terminal of a low-voltage power supply network 1 of the vehicle is connected to the positive input terminal of a mechanical control normally closed switch 4 by a positive wire 2, the negative output terminal of the low-voltage power supply network 1 of the vehicle is connected to the negative input terminal of the mechanical control normally closed switch 4 by a negative wire 3, the positive output terminal of the mechanical control normally closed switch 4 is connected to the positive input terminal of a low-voltage power supply of a drive device controller 7 by a positive wire 6, and the negative output terminal of the mechanical control normally closed switch 4 is connected to the negative input terminal of a low-voltage power supply of a drive device controller 7 by a negative wire 5. When the driver mistakenly steps on the accelerator pedal as a brake pedal, the vehicle accelerates against the driver's intention, and the panicked driver quickly presses the conspicuous mechanical control normally closed switch 4 to cut off the low-voltage power supply of the drive device controller 7, the program software in the drive device controller 7 stops running, the drive device stops outputting power, and the drive device stops outputting driving torque and speed.
