Claim 2:
3. The vehicle control device according to claim 2,
wherein the comparator is further configured to receive a third voltage from the air bag module and output a low level signal to the control switch, so that the control switch is controlled to be switched off according to the low level signal, and the battery management system is powered by the power supply after the control switch is switched off, wherein the third voltage is sent out by the air bag module when the vehicle collision event is not detected by the air bag module;
wherein when the first terminal of the comparator is a non-inverting input, the second terminal of the comparator is an inverting input, the third voltage is less than the second voltage; when the first terminal of the comparator is an inverting input, the second terminal of the comparator is a non-inverting input, the third voltage is higher than the second voltage.
