The invention discloses a hybrid electric vehicle and a driving power generation control method and device.The hybrid electric vehicle comprises a power battery, a driving motor, an engine and a power generator connected with the engine. Acquiring gradient information of the target road, consumed power of vehicle accessories, actual consumed power of a driving motor and uncompensated driving generated power; acquiring ramp compensation generation power according to the gradient information; according to the ramp compensation generation power, the vehicle accessory consumption power, the actual consumption power of the driving motor and the non-compensation driving generation power, the driving generation total power is obtained; and performing power generation control on the engine and the generator according to the driving power generation total power. Therefore, when the vehicle is subjected to driving power generation control, the corresponding ramp compensation power generation power is obtained according to the gradient information of the target road, so that the battery electric quantity of the whole vehicle during driving on the ramp is ensured, and the driving experience of a user is optimized.

    本发明公开了一种混合动力汽车及其行车发电控制方法和装置,其中,混合动力汽车包括动力电池、驱动电机、发动机和与发动机相连的发电机,方法包括以下步骤:在混合动力汽车进入发电模式时,获取目标道路的坡度信息、整车附件消耗功率、驱动电机实际消耗功率和无补偿行车发电功率;根据坡度信息获取坡道补偿发电功率;根据坡道补偿发电功率、整车附件消耗功率、驱动电机实际消耗功率和无补偿行车发电功率,获取行车发电总功率;根据行车发电总功率对发动机和发电机进行发电控制。由此,在对车辆进行行车发电控制时,针对目标道路的坡度信息获取对应的坡道补偿发电功率,从而,确保整车在坡道上行驶时的电池电量,优化用户驾驶体验。
