The invention discloses a hybrid electric vehicle driving control method, which comprises the following steps of: controlling a vehicle to enter an automatic driving formation; obtaining a theoretical driving track of the vehicle and a real-time position of the front vehicle; according to the real-time position of the vehicle, the real-time position of the front vehicle and the theoretical driving track of the vehicle, the current vehicle moving distance of the vehicle is obtained; the average driving speed of the vehicle is obtained according to the driving distance of the vehicle within the preset duration; according to the current vehicle moving distance and the average driving speed of the vehicle, the current predicted vehicle moving duration of the vehicle is calculated, and the predicted total energy consumption of the vehicle is obtained; judging that an engine needs to be started to charge the vehicle-mounted battery according to the current electric quantity and the predicted total energy consumption of the vehicle-mounted battery, and judging that the engine can be started according to the current predicted vehicle moving duration of the vehicle; and the vehicle is kept in a neutral gear, the engine is started to charge the vehicle-mounted battery, and the engine is controlled to stop before the vehicle is moved this time. The phenomenon of potential safety hazards caused by fatigue driving of the driver can be avoided, and the energy consumption of the vehicle can be reduced.
本发明公开了混合动力车行驶控制方法,该混合动力车行驶控制方法,控制车辆进入自动驾驶编队后;获取车辆的理论行驶轨迹和前车的实时位置;依据车辆的实时位置、前车的实时位置和车辆的理论行驶轨迹获取车辆本次的挪车距离;依据车辆前设定时长内的行驶距离获取车辆的平均行驶速度;依据车辆本次的挪车距离和平均行驶速度计算车辆本次的预计挪车时长,并获取车辆的预计总能耗;依据车载电池当前的电量和预计总能耗判断需要启动发动机对车载电池充电,依据车辆本次的预计挪车时长判断能够启动发动机;车辆保持空挡,启动发动机对车载电池充电,在本次挪车前控制发动机停机。能避免驾驶员由于疲劳驾驶导致的造成安全隐患的现象,能降低车辆的能耗。
