The invention relates to the technical field of vehicle torque, in particular to a torque recovery method, a torque recovery device, a vehicle and computer equipment. The torque recovery method comprises the steps that the vehicle is in a low-power working condition; calculating a recovery restriction torque based on the recovery restriction power and the rotating speed of the motor, and comparing the initial target torque with the recovery restriction torque; in response to the condition that the initial target torque exceeds the recovery restriction torque, performing first restriction on the initial target torque by using the recovery restriction torque to obtain a first request torque, and sending a first torque request to the motor control module; and in response to the condition that the initial target torque does not exceed the recovery restriction torque, analyzing the bound torque in combination with the vehicle speed and the recovery restriction power, performing second restriction on the initial target torque by using the bound torque to obtain a second request torque, and sending a second torque request to the motor control module. By adopting the method, the working condition of the vehicle can be identified, and the influence on energy consumption is reduced while the smoothness of the low-power state of the vehicle is optimized.

    本申请涉及车辆扭矩技术领域,特别是涉及一种扭矩回收方法、扭矩回收装置、车辆以及计算机设备。扭矩回收方法包括:车辆处于低功率工况;基于回收制约功率以及电机转速计算回收制约扭矩,比对初始目标扭矩与回收制约扭矩;响应于初始目标扭矩超过回收制约扭矩,利用回收制约扭矩对初始目标扭矩进行第一约束,得到第一请求扭矩,向电机控制模块发送第一扭矩请求;响应于初始目标扭矩未超过回收制约扭矩,结合车速与回收制约功率二者解析束缚扭矩,利用束缚扭矩对初始目标扭矩进行第二约束,得到第二请求扭矩,向电机控制模块发送第二扭矩请求。采用本方法能够对车辆工况进行识别,并在优化车辆低功率状态平顺性的同时,降低对能耗的影响。
