The invention provides a vehicle torque control method, device and equipment and a storage medium, relates to the technical field of vehicle control, vehicle performance monitoring and the like, and can be applied to unmanned vehicle control, electric vehicle safety monitoring and other scenes. The specific implementation scheme comprises the steps of determining an allowable value of request torque output by a vehicle according to the speed of the vehicle and the opening degree of an accelerator pedal; according to the driving parameters of the vehicle and the inherent parameters of the vehicle, determining that the output torque of the vehicle motor, the type of the driving parameters and the type of the inherent parameters are related to the communication state of the vehicle motor and/or the effectiveness of a motor rotating speed signal; when the allowable value of the request torque is smaller than the output torque, determining a target request torque according to the allowable value of the request torque and the output torque; and controlling the request torque output by the vehicle according to the target request torque. According to the invention, when the communication of the vehicle motor is lost or the feedback torque signal is incredible, the request torque can be accurately controlled.

    本公开提供了一种车辆扭矩控制方法、装置、设备及存储介质,涉及车辆控制、车辆性能监控等技术领域,可应用于无人驾驶车辆控制、电动车辆安全监控等场景下。具体实现方案包括:根据车辆的车速、加速踏板开度,确定车辆输出的请求扭矩的允许值;根据车辆的行驶参数和车辆的固有参数,确定车辆电机的输出扭矩,行驶参数的类型和固有参数的类型与车辆电机的通讯状态,和/或,电机转速信号的有效性相关;当请求扭矩的允许值小于输出扭矩时,根据请求扭矩的允许值、输出扭矩,确定目标请求扭矩;根据目标请求扭矩,控制车辆输出的请求扭矩。本公开能够在车辆电机的通讯丢失或者反馈的扭矩信号不可信时,实现对请求扭矩的准确控制。
