The invention discloses an automobile and an automobile motor controller hill-holding control method and system. The method comprises the following steps that S10, when it is collected that the gear of the automobile is in a driving gear, no braking signal exists and no hand brake signal exists, the next step is executed; s20, false hill-holding prevention detection is carried out, and the next step is carried out when the false hill-holding prevention detection is passed; s30, the rotating speed value of a driving motor of the automobile is collected, and when it is detected that the rotating speed value is within the set range, the automobile enters a hill-holding mode; and S40, the driving motor is controlled to enter a locked-rotor mode, and when it is detected that the rotating speed value exceeds the set range or the temperature of the driving motor and the motor controller exceeds the set range, the slope parking mode is quitted. According to the vehicle motor controller slope parking control method and system, slope parking is achieved in a motor controller control mode, and the situation of vehicle sliding or vehicle rushing during slope parking is avoided.
本发明公开一种汽车及汽车电机控制器驻坡控制方法和系统,该方法包括如下步骤:S10,于采集到汽车的挡位处于驱动挡、无制动信号以及无手刹信号时进入下一步骤;S20,进行防误驻坡检测,并于防误驻坡检测通过时进入下一步骤;S30,采集汽车的驱动电机的转速值,并于检测到转速值在设定范围内时进入驻坡模式;S40,控制驱动电机进入堵转模式,直至检测到转速值超出设定范围、或驱动电机以及电机控制器的温度超出设定范围时,退出驻坡模式。本发明的汽车电机控制器驻坡控制方法及系统采用电机控制器控制的形式实现驻坡,避免造成驻坡溜车或冲车情况。
