The invention belongs to the technical field of hybrid electric vehicles, and discloses a clutch disengagement control method and system and a computer storage medium. According to the method, the torque unloading time of an engine is shortened by increasing the torque slope of engine torque unloading, and the clutch disengagement execution time is shortened by sending jitter torque to the front end of a clutch. The electromagnetic clutch solves the problems that the clutch is easy to seize and difficult to disconnect, and has the advantage of higher success rate of disengagement of the electromagnetic clutch. In addition, by optimizing the control strategy, the disengagement time of the electromagnetic clutch is shortened, and trigger clutch disengagement fault alarms are reduced. According to the invention, the torque unloading time of the engine can be shortened, and the clutch disengagement execution time can be shortened, so that the total clutch disengagement time is shortened, the whole vehicle can be quickly and smoothly switched into a series connection mode from a parallel connection mode, temporary power interruption caused by overlong clutch disengagement time is avoided, and the driving experience is improved.

    本发明属于混合动力汽车技术领域,公开了一种离合器脱开控制方法、系统及计算机存储介质。所述方法通过增大发动机卸扭的扭矩斜率来缩短发动机卸扭时间,并通过向离合器前端发送抖动扭矩来缩短离合器脱开执行时间。本发明解决了离合器易咬死、难断开的问题,具有电磁离合器脱开成功率更高的优点。而且,本发明通过优化控制策略缩短了电磁离合器的脱开时间,减少了触发离合器脱开故障报警。本发明既能减少发动机卸扭时间,又能减少离合器脱开执行时间,从而减少了离合器脱开总时间,可以让整车从并联模式快速丝滑地切入到串联模式,避免了离合器脱开时间过长引起动力暂时性的中断,提高了驾驶体验。
