The invention provides a hybrid electric vehicle parallel motor gear shifting speed regulation target calculation method and device, and the method comprises the steps: obtaining vehicle operation information which comprises first information for representing gear shifting control and second information for representing the acceleration and deceleration states of a vehicle; calculating a basic speed regulation target of the synchronized end of the synchronizer according to the first information, and calculating the offset of the speed regulation target of the synchronized end of the synchronizer according to the second information; and calculating a motor gear shifting speed regulation target by utilizing the basic speed regulation target and the speed regulation target offset. When the vehicle is in an acceleration or deceleration state, the situation that the synchronizer speed difference is increased in the period from the completion of motor speed regulation to the start of synchronizer synchronization can be relieved or even avoided, so that the synchronization time is shortened, and rapid synchronization is realized.
本发明提供了一种混合动力汽车并联电机换挡调速目标计算方法及装置,所述方法包括:获取车辆运行信息,所述车辆运行信息中包含有用于表征换挡控制的第一信息和用于表征车辆加减速状态的第二信息;根据所述第一信息计算同步器被同步端的基础调速目标,以及根据所述第二信息计算所述同步器被同步端的调速目标偏移量;利用所述基础调速目标和所述调速目标偏移量计算电机换挡调速目标。在车辆处于加速或者减速状态时,本发明可以缓解甚至避免在电机调速完成至同步器开始同步这一时段内同步器速差增加的情况,从而减少同步时间、实现快速同步。
