The invention provides a method for controlling a motor to be restarted when a motor of a compression pump for supplying air to an air compressor of a vehicle braking system fails to start, and the method comprises the following steps: starting the motor of the compression pump when determining that the air pressure P in a compressed air storage device is less than or equal to the lower limit P, and detecting whether the motor is normally started or not; when it is detected that starting of the motor fails, the state of the DCAC motor controller is changed from PWM control to standby so that power supply to the motor can be stopped, and the motor can be stopped for a period of time t; detecting the pressure value P of the compressed air in the compressed air storage at the moment; and the motor is restarted with the starting current I corresponding to the P value until the motor is normally started and then works for a period of time, so that the air pressure reaches the upper limit of the P. In this way, the situation that the motor is overheated due to the fact that the motor is always powered when the motor fails is avoided, and stable supply of compressed air is guaranteed.

    本申请提供一种在向车辆制动系统的空气压缩机供应空气的压缩泵电机启动失效时控制电机重启的方法,所述方法包括以下步骤:在确定压缩空气存储器中的空气压力P≤P下限时启动压缩泵的电机,并检测电机的启动是否正常;在检测到电机启动失效时,使DCAC电机控制器的状态从PWM控制改变到待机,以停止对电机供电,并使电机停止一段时间t;检测此时压缩空气存储器内的压缩空气的压力值P;并以与P值相对应的启动电流I来重启电机,直至电机启动正常后工作一段时间,以使空气压力达到P上限,这样既避免了电机在失效时一直被供电从而导致电机过热,也保证了压缩空气的稳定供给。
