The invention provides a hybrid electric vehicle power engine smooth switching method and device. The method comprises the following steps: acquiring a first driving state of the hybrid vehicle at the current moment and road condition information of a driving road section of the hybrid vehicle; according to the first driving state and the road condition information, a second driving state of the hybrid vehicle at the next moment of the current moment is predicted, the first driving state and the second driving state both comprise the speed, the acceleration and the driving track category, and the road condition information comprises distribution of vehicles, pedestrians and obstacles; based on the second driving state, whether the hybrid electric vehicle needs to switch a power engine or not is judged, and the power engine comprises an engine and a motor; and when the power engine needs to be switched, the power engine is switched by utilizing a smooth switching algorithm. By adopting the technical means, the problem that the switching of the power engine of the hybrid vehicle lags behind the change of the driving state of the vehicle in the prior art and the timely switching of the power engine cannot be realized is solved.

    本申请提供了一种混动汽车动力引擎平滑切换方法及装置。该方法包括:获取混动汽车在当前时刻的第一行驶状态和其行驶路段的路况信息;依据第一行驶状态和路况信息预测混动汽车在当前时刻的下一时刻的第二行驶状态,其中,第一行驶状态和第二行驶状态均包括速度、加速度和行驶轨迹类别,路况信息包括车辆、行人和障碍物的分布;基于第二行驶状态判断混动汽车是否需要切换动力引擎,其中,动力引擎包括发动机和电动机;当需要切换动力引擎时,利用平滑切换算法完成动力引擎的切换。采用上述技术手段,解决现有技术中混动汽车动力引擎的切换滞后于汽车行驶状态的变化,不能实现动力引擎的及时切换的问题。
