The invention provides a control system suitable for an electric vehicle vacuum pump and a control method. According to the control system and the control method, the vacuum pump is controlled to be started and stopped according to different vacuum pressure high/low thresholds at different vehicle speeds, and the operation time threshold of the constant rotation fault of the vacuum pump at different vehicle speeds are used for finely distinguishing the service time of the vacuum pump under different working conditions, so that the service life of the vacuum pump is prolonged. By refining vacuum pump faults and fault detection conditions, various processing methods are designed and formulated according to different actual working conditions, and the driving safety of a vehicle is guaranteed. Besides, by setting the minimum vacuum pump operating time, the situation that the vacuum pump is frequently started for operation and the driving feeling of a driver is affected is effectively avoided.
本发明提供一种适用于电动车真空泵的控制系统及其控制方法。根据本发明的控制系统及其控制方法,通过不同车速下对应不同的真空压力高/低阈值控制真空泵的启动和停止,和不同车速下真空泵常转故障的运行时间阈值,精细区分真空泵在不同工况下的使用时间,增加真空泵的使用寿命。通过细化真空泵故障和故障检测条件,根据不同的实际工况,设计制定多种处理方法,保证车辆的行车安全。此外,本发明的控制方法通过设定最低真空泵运行时间,有效避免真空泵频繁启动运行,影响驾驶员的驾驶感受。
