The invention is suitable for the technical field of motor control, and provides a control method and device for a motor in a vehicle and the vehicle, and the method comprises the steps: obtaining a first request torque of the motor at an (i-2) th sampling moment, a second request torque of the motor at an (i-1) th sampling moment, and a third request torque of the motor at an ith sampling moment; judging whether the first request torque, the second request torque and the third request torque meet a first preset requirement or not; and when the first request torque, the second request torque and the third request torque meet the first preset requirement, the motor is controlled to run for preset time based on the second request torque. When the change direction of the request torque of the vehicle is changed, the motor runs for the preset time according to the second request torque, so that the vehicle can run according to the new request torque when running stably at the second request torque, and shaking of the vehicle is reduced.

    本申请适用于电机控制技术领域,提供了一种车辆中电机的控制方法、装置及车辆,该方法包括:获取电机在第i‑2个采样时刻的第一请求扭矩、在第i‑1个采样时刻的第二请求扭矩和在第i个采样时刻的第三请求扭矩;判断第一请求扭矩、第二请求扭矩和第三请求扭矩是否满足第一预设要求;在第一请求扭矩、第二请求扭矩和第三请求扭矩满足第一预设要求时,基于第二请求扭矩,控制电机运行预设时间。本申请在车辆的请求扭矩的变化方向改变时,将电机按照第二请求扭矩运行预设时间,以使得车辆可以在第二请求扭矩运行平稳时,再按照新的请求扭矩进行运行,减少了车辆的抖动。
