The invention discloses an oil pre-charging control method for a dual-motor hybrid power parallel mode clutch. The oil pre-charging control method comprises the following steps that S1, a whole vehicle control unit obtains a plurality of signals of a current vehicle; s2, judging an oil pre-charging control activation condition of the parallel mode clutch; s3, the clutch is pre-charged with oil; s4, recording the oil pre-charging times of the clutch; s5, the oil pressure of the clutch is kept; s6, reducing the oil pressure of the clutch. The method is used for reducing the gear shifting time overhead of the vehicle in a parallel connection mode, improving the vehicle acceleration performance, improving the vehicle dynamic property and improving the vehicle driving comfort.
本发明公开了一种双电机混合动力并联模式离合器预充油控制方法,包括以下步骤:S1.整车控制单元获取当前车辆的多个信号;S2.判断并联模式离合器预充油控制激活条件;S3.离合器预充油;S4.记录离合器预充油次数;S5.保持离合器油压;S6.降低离合器油压。用于降低车辆在并联模式下换挡时间开销,提高车辆加速性能,提升车辆动力性,提升车辆驾乘舒适性。
