The invention provides a vehicle, a high-voltage discharge system of the vehicle and a control method of the high-voltage discharge system of the vehicle. The system comprises a control signal receiving end which is used for receiving a first control signal output by a control chip, a discharge time control circuit and a logic control circuit, wherein the discharge time control circuit is used for generating a second control signal according to the duration of a discharge control state of a first control signal; and the logic control circuit is used for controlling the high-voltage discharge circuit to be turned on or turned off according to the first control signal and the second control signal so as to discharge or stop discharging a high-voltage power supply of the vehicle. Therefore, by adding the discharge time control circuit, on or off of the high-voltage discharge circuit can be effectively controlled under the condition that the control chip is out of control, the risk of out-of-control discharge of the high-voltage power supply caused by out-of-control of the control chip is avoided, discharge safety of the high-voltage power supply is guaranteed, and in addition, the system is simple in circuit structure and low in cost, and meanwhile, the method also has relatively high applicability.
