The belt slipping control scheme of the hybrid vehicle comprises the steps that the belt slipping rate is monitored in the vehicle running process, it is determined that a belt does not slip when the belt slipping rate is smaller than the preset minimum slipping rate, and when the belt slipping rate is larger than the preset maximum slipping rate, a heavy slipping fault of the belt is reported, when the belt slip rate is between the minimum slip rate and the maximum slip rate, it is determined that the belt slips slightly; and executing motor torque limit value control and accumulating the number of slight slips within the latest driving cycle of the vehicle in a case where it is determined that the belt slips slightly, and reporting a slight slip failure of the belt in a case where the number of slight slips within the latest driving cycle of the vehicle is greater than the maximum slip number threshold.
一种混动车辆皮带打滑控制方案包括:在车辆运行过程中对皮带打滑率进行监控,并且在皮带打滑率小于预设的最小打滑率时,确定皮带没有打滑,在皮带打滑率大于预设的最大打滑率时,报告皮带的重度打滑故障,在皮带打滑率位于最小打滑率与最大打滑率之间时,确定皮带轻微打滑;以及在确定皮带轻微打滑的情形下,执行电机扭矩限值控制,并且累计车辆最近行驶周期内的轻微打滑次数,在车辆最近行驶周期内的轻微打滑次数大于最大打滑次数阈值的情况下,报告皮带的轻微打滑故障。
