The invention relates to the technical field of vehicle hybrid gearbox control, in particular to a flywheel unlocking and unloading control strategy for a single planet row type hybrid gearbox, electronic equipment and a vehicle. By means of real-time control over the flywheel unlocking and unloading process, in combination with calculation of forward and reverse unloading torque and unloading program execution in the flywheel unlocking process, successful unlocking of the hybrid gearbox flywheel under different working conditions can be guaranteed, an ECVT dual-motor pure electric drive mode is successfully quitted, and the vehicle driving experience is improved; meanwhile, through a flywheel unlocking forward and reverse unloading completion judgment method and an unloading completion judgment method under the abnormal condition, flywheel unloading completion can be accurately judged, and flywheel unlocking time sequence control is smoothly carried out.

    本发明涉及车辆混动变速箱控制技术领域,具体涉及一种单行星排式混动变速箱飞轮解锁卸载控制策略及电子设备、车辆。本发明通过飞轮解锁卸载过程的实时控制,结合飞轮解锁过程中正反向卸载扭矩的计算及卸载程序执行,能够确保不同工况下混动变速箱飞轮的成功解锁,从而顺利退出ECVT双电机纯电驱动模式,提升车辆驾驶体验;同时,通过飞轮解锁正反向卸载完成判断方法及异常情况下卸载完成判断方法,能够准确判断飞轮卸载完成,使飞轮解锁时序控制顺利进行。
