The invention discloses an automobile driving motor reversing control method, when a steering instruction is received, an execution torque needing to be provided by a steering motor is obtained, and when the steering motor is driven, the method comprises the following steps that 1, the torque of the steering motor is driven to be increased to a meshing torque, so that a gear of the steering motor is meshed with a transmission part; 2, a rotating motor is driven to increase torque to preheating torque; and step 3, increasing the torque of the steering motor to an execution torque value. According to the characteristics of the motor gear, driving control is performed after slow meshing, so that the problem of abnormal sound caused by shaking is effectively avoided.
本发明揭示了一种汽车驱动电机换向控制方法,当接收到转向指令时获取到转向电机需要提供的执行扭矩,驱动转向电机时包括以下步骤:步骤1、驱动转向电机增加扭矩至啮合扭矩,使转向电机的齿轮与传动部件啮合;步骤2、驱动转动电机增加扭矩到预热扭矩;步骤3、增加转向电机扭矩至执行扭矩数值。本发明根据电机齿轮特性,缓慢啮合后再进行驱动控制,从而有效的避免因抖动造成的异响问题。
