A series-parallel switching method, device and equipment for a hybrid vehicle and a storage medium relate to the technical field of vehicle control, and comprise: when the hybrid vehicle is switched from a series driving mode to a parallel driving mode, according to the obtained rotating speed of the engine end and the rotating speed of the wheel end of a switchable roller one-way clutch, controlling the switchable roller one-way clutch to switch the series driving mode to the parallel driving mode; the switchable roller one-way clutch is controlled to be closed; when the hybrid vehicle is switched from the series drive mode to the parallel drive mode, the switchable roller one-way clutch is controlled to be disconnected according to the obtained rotating speed difference between the engine end and the wheel end of the switchable roller one-way clutch, and the problems that in the related technology, a hydraulic clutch is high in price and cost, and the service life of the hydraulic clutch is influenced are solved. The technical problems that in the prior art, the control process of series-parallel connection switching of the hybrid vehicle needs to be strictly carried out according to steps, and control is not flexible enough are solved, the switching control process of the series-parallel connection driving modes of the vehicle can be simpler, more convenient and more flexible, and the cost is lower.

    一种混动车辆串并联切换的方法、装置、设备及存储介质,涉及车辆控制技术领域,包括:当混动车辆由串联驱动模式切换到并联驱动模式时,则根据获取到的所述可切换滚子单向离合器的发动机端的转速和车轮端的转速,控制所述可切换滚子单向离合器闭合;当混动车辆由串联驱动模式切换到并联驱动模式时,则根据获取到的所述可切换滚子单向离合器的发动机端与车轮端之间的转速差,控制所述可切换滚子单向离合器断开,解决了相关技术中采用液压式离合器的价格成本高,且混动车辆串并联切换的控制过程中必须严格按照步骤进行,控制上不够灵活的技术问题,本申请能够使车辆的串并联驱动模式的切换控制过程更简便灵活,且成本更低。
