The invention provides a vehicle power-off control method, device and module, a storage medium, a program product, a power supply circuit and a vehicle. The power supply circuit of the vehicle comprises a battery assembly, a battery management module, a power domain control module and a high-voltage assembly, wherein the high-voltage assembly at least comprises a motor driving control module and a power-assisted steering system inversion module. Wherein the power domain control module is connected with the battery management module, and the battery assembly is respectively connected with the battery management module, the motor driving control module and the power-assisted steering system inversion module. The method is applied to a power domain control module and comprises the following steps: in response to a power-off instruction, controlling a battery assembly to stop supplying power through a battery management module; and executing high-voltage discharge operation, wherein the high-voltage discharge operation comprises the step of enabling the inversion module of the power-assisted steering system to assist the motor driving control module to perform high-voltage discharge. According to the method, the discharging efficiency of the motor driving control module is improved, and the safety of the vehicle is improved.
