The invention relates to an automobile hybrid power system control technology, in particular to a hybrid power automobile gear shifting control method. After the gear shifting request is sent out, the urgency of the gear shifting request is calculated, and the priority of gear shifting suppression at the moment is calculated; executing gear shifting when the gear shifting urgency is greater than the priority of gear shifting suppression, otherwise, executing suppression; and after the suppression is executed until the current suppression is relieved, returning to query other gear shifting suppression priorities, and executing gear shifting until the gear shifting urgency is greater than the gear shifting suppression priorities. According to the method, the gear shifting opportunity of the multi-engine and multi-shaft driving hybrid electric vehicle system is controlled, so that the gear shifting opportunity is reasonably controlled, and good coordination is achieved among reflecting the driving intention, comfortable vehicle driving and stable vehicle running.
本发明涉及汽车混合动力系统控制技术,具体涉及一种混合动力汽车换挡控制方法。换挡请求发出后,计算换挡请求的迫切性,并计算此时的换挡抑制的优先性;换挡迫切性大于换挡抑制的优先性时执行换挡,否则执行抑制;执行抑制至当前抑制解除后,返回查询其它换挡抑制优先性,直至换挡迫切性大于换挡抑制优先性时执行换挡。本发明针对多引擎、多轴驱动的混合动力汽车系统换挡时机进行控制,使换挡时机控制合理,在体现驾驶意愿、车辆驾驶舒适、车辆行驶稳定之间取得良好的协调性。
