Classification: CPC B | IPC B

Claim 0:
1. A vehicle control device, comprising:
a first resistor circuit, a comparator, a control switch, and a second resistor circuit;
wherein a first terminal of the comparator is connected with an air bag module, a second terminal of the comparator is connected with a first terminal of the first resistor circuit, a third terminal of the comparator is connected with a power supply, a fourth terminal of the comparator is grounded, and a fifth terminal of the comparator is connected with a first terminal of the control switch;
a second terminal of the control switch is connected with a battery management system, and a third terminal of the control switch is grounded;
a second terminal of the first resistor circuit is connected with the power supply, and a third terminal of the first resistor circuit is grounded;
a first terminal of the second resistor circuit is connected with the power supply, and a second terminal of the second resistor circuit is connected with the battery management system;
the comparator is configured to receive a first voltage from the air bag module and output a high level signal to the control switch to enable the control switch to be switched on according to the high level signal, enable the battery management system to be grounded after the control switch is switched on, and enable the battery management system to be powered off after the battery management system is grounded, wherein the first voltage is sent out by the air bag module when a vehicle collision event is detected.
