The invention provides a hybrid electric vehicle driving control method and device, and the method comprises the steps: obtaining the current navigation information, real-time road condition information and the current vehicle remaining electric quantity of a target vehicle when a vehicle control unit of the target vehicle enters a self-recognition engine starting driving mode; according to the current navigation information and the real-time road condition information, segmenting the whole distance according to a navigation plan line to obtain road segment information; estimating the electric quantity required by pure electric power according to the road section segmentation information to obtain the estimated total energy consumption of pure electric driving in the whole process, switching the control mode of a vehicle controller into a hybrid power control mode when the estimated total energy consumption is greater than the residual electric quantity of the vehicle, and controlling the vehicle controller to be in a hybrid power control mode based on the strategies of high-speed oil direct driving and low-speed electric driving. And the vehicle control unit carries out hybrid power driving control on the target vehicle, so that the fuel consumption is obviously reduced, and meanwhile, the driving experience is improved.

    本申请提供一种混合动力汽车行驶控制方法及装置,该方法包括:在目标车辆的整车控制器进入自识别发动机启动驾驶模式时,获取当前导航信息、实时路况信息以及目标车辆当前的整车剩余电量;根据当前导航信息和实时路况信息,对整个路程按照导航规划行分段,得到路段分段信息;根据路段分段信息进行纯电动力所需电量估算,得到全程纯电行驶估算总能耗,并在其大于整车剩余电量时,将整车控制器的控制模式切换为混合动力控制模式,基于高速用油直驱,低速用电驱动的策略,使整车控制器对目标车辆进行混合动力行驶控制,从而以此显著降低燃油消耗,同时提升驾驶体验。
