Embodiment
[0033] The flow chart of the flushing control of the electromagnetic valve of the wet dual-clutch automatic gearbox of the present invention is as attached figure 1 shown. Accelerator pedal position, brake pedal position and shift lever position are collected (1). Determine whether the collected accelerator pedal is depressed, whether the preferred opening is greater than 40%, whether the brake pedal is depressed, whether the preferred opening is greater than 40%, and whether the shift handle is in position P (2). If the accelerator pedal is greater than 40%, the brake pedal opening is greater than 40%, and the shift lever is in the P position (3), judge whether the pressure of clutch 1 and clutch 2 are both 0, if so, it means that clutch 1 and clutch 2 are disengaged (4). If clutch 1 and clutch 2 are disengaged, call COV1, CPCV1 cleaning function (5), if CPCV1 cleaning function ends, call COV2, CPCV2 cleaning function (6), if COV2, CPCV2 cleaning ends, call MPCV cleaning fu...
