The invention relates to a power-assisted torque determination method and device, a vehicle and a storage medium, and relates to the technical field of communication. The method comprises the steps that in response to a failure signal of a torque sensor, vehicle speed information, vehicle rotation angle information, a torque weight coefficient and the actual transverse acceleration of a vehicle are obtained; and determining a target lateral acceleration of the vehicle according to the vehicle speed information and the vehicle corner information. And determining a vehicle speed weight coefficient corresponding to the vehicle speed information according to a preset corresponding relation. And according to the target transverse acceleration, the torque weight coefficient, the actual transverse acceleration and the vehicle speed weight coefficient, target assistance torque is determined, and the target assistance torque is used for controlling steering of the vehicle at the current moment. Therefore, under the condition that the torque sensor fails, the turning angle information of the vehicle can be obtained through the turning angle sensor, the power-assisted torque is determined through the turning angle information of the vehicle, and power-assisted steering is achieved.
