The invention discloses a hybrid power system gear shifting control method and device, and relates to the technical field of hybrid power systems. When the gear shifting time exceeds the preset time threshold value corresponding to the gearbox temperature, gear shifting is stopped, and synchronizer damage caused by long-time abrasion of a synchronizing ring of a synchronizer can be avoided; gear shifting is stopped when the current of the gear shifting motor exceeds the preset current threshold value corresponding to the temperature of the gearbox, and a synchronizer and the gear shifting motor can be prevented from being damaged; if the current rotating speed difference between the driving motor and the engine is larger than or equal to the rotating speed difference obtained last time, it represents that the rotating speed difference between the driving motor and the engine is not decreased in the gear shifting process, and at the moment, gear shifting is stopped to avoid damage to a synchronizer.
本发明公开了混合动力系统换挡控制方法及装置,涉及混合动力系统技术领域。本发明在换挡时间超过变速箱温度对应的预设时间阈值时停止换挡,可以避免同步器的同步环长时间磨损导致同步器损坏;在换挡电机电流超过变速箱温度对应的预设电流阈值时停止换挡,可以避免损坏同步器和换挡电机;若驱动电机与发动机当前的转速差大于或等于上一次获取的转速差,代表换挡过程中驱动电机与发动机的转速差未变小,此时停止换挡可以避免损坏同步器。
