A vehicle control device, a vehicle control system and a vehicle are provided in the embodiments of the present invention, the vehicle control device includes a first resistor circuit, a comparator, a control switch, and a second resistor circuit; the comparator is configured to receive a first voltage which is output by 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, and 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. According to the embodiments of the present invention, the power supply of the vehicle can be cut off quickly when the vehicle collision event occurs, time spent on switching on/off the control switch is reduced, and the reliability is improved.
