The invention provides a clutch self-learning control method and device, a computer program product and a vehicle, and the method comprises the steps: controlling an engine to run at a preset rotating speed, and controlling a clutch to be gradually closed from an off state for multiple times, so as to obtain a plurality of first sliding friction points and a plurality of first minimum combination positions, the first sliding friction point is a clutch position where the motor rotating speed is equal to a calibratable threshold value, and the first minimum combination position is a position where the rotating speed difference between the engine and the motor is smaller than the calibratable threshold value; determining a second sliding friction point, a third sliding friction point, a second minimum combination position and a third minimum combination position according to the plurality of first sliding friction points and the plurality of first minimum combination positions; a corrected sliding friction point is calculated according to the life cycle coefficient, the second sliding friction point and the third sliding friction point, a corrected minimum combination position is calculated according to the life cycle coefficient, the second minimum combination position and the third minimum combination position, a corrected maximum separation position is determined according to the corrected sliding friction point, and the problem that clutch position correction is inaccurate is solved.
本申请提供了一种离合器自学习的控制方法、装置、计算机程序产品和车辆,该方法包括:控制发动机以预定转速运行并多次控制离合器从断开状态逐渐闭合,得到多个第一滑摩点和多个第一最小结合位置,第一滑摩点为电机转速等于可标定阈值的离合器位置,第一最小结合位置为发动机与电机的转速差小于可标定阈值;根据多个第一滑摩点和多个第一最小结合位置确定第二滑摩点、第三滑摩点、第二最小结合位置和第三最小结合位置;根据寿命周期系数、第二滑摩点和第三滑摩点计算得到校正滑摩点,根据寿命周期系数、第二最小结合位置和第三最小结合位置计算得到校正最小结合位置,并根据校正滑摩点确定校正最大分离位置,解决了离合器位置校正不准确的问题。
