The invention relates to the technical field of hybrid electric vehicles, and discloses a hybrid power mode control method, a power controller, a system and a vehicle, and whether a gradient parameter is greater than a preset gradient or not is judged when it is detected that an environment condition reaches a critical condition for switching a series-parallel connection mode in the vehicle running process. If yes, whether the acceleration parameter is larger than the first threshold value or whether the pedal opening change parameter is larger than the second threshold value or not continues to be detected. If any one of the two judgments is yes, the vehicle is not immediately switched to the series connection mode, but the vehicle is controlled to maintain the parallel connection mode to continue to run within the set duration, the problem that the rotating speed is increased when the parallel connection mode is switched to the series connection mode is avoided, noise generated when an engine runs is avoided, and the user experience is improved through the method.

    本发明涉及混合动力汽车技术领域,公开了混合动力模式的控制方法、动力控制器、系统及车辆,本发明通过在车辆行驶过程中检测到环境条件达到串并联模式切换的临界条件时,判断坡度参数是否大于预设坡度。如果是,则继续检测加速度参数是否大于第一阈值,或,踏板开度变化参数是否大于第二阈值。如果两个判断中任一判断结果为是,则不立即将车辆切换至串联模式,而是控制车辆在设定时长内维持并联模式继续行驶,规避从并联切换到串联时转速升高的问题,从而避免发动机运行时产生噪声,本方法提升了用户体验。
