The invention provides a motor output torque control method and device and a motor controller, the method is executed by the motor controller, and the motor controller interacts with a vehicle controller; the method comprises the steps that a torque request of a vehicle controller is monitored, and whether preset automatic control conditions are met or not is determined according to the torque request; the preset self-control conditions include that the torque value indicated by the torque request of the vehicle controller in the past preset time period is in a descending trend, and the torque value enters a preset range; when the preset self-control condition is met, the current vehicle speed and the current working condition are obtained; the current vehicle speed refers to the vehicle speed when the torque value indicated by the torque request enters the preset range, and the current working condition is one of the preset working conditions; and determining a first target control strategy according to the current vehicle speed and the current working condition, and controlling the motor output torque according to the first target control strategy. The method provided by the invention is used for improving the smoothness of the vehicle during driving.

    本申请提供一种电机输出扭矩控制方法、装置及电机控制器,其中,该方法由电机控制器执行,电机控制器与车辆控制器交互;方法包括:监测车辆控制器的扭矩请求,并根据扭矩请求确定是否满足预设自控条件;预设自控条件包括:车辆控制器在过去预设时间段内的扭矩请求指示的扭矩值呈下降趋势、扭矩值进入预设范围;在满足预设自控条件时,获取当前车速和当前工况;当前车速是指车辆在扭矩请求指示的扭矩值进入预设范围时的车速,当前工况为预设工况中的一种;根据当前车速和当前工况,确定第一目标控制策略,按照第一目标控制策略控制电机输出扭矩。本申请的方法,用以提升车辆行驶时的平顺性。
