The invention belongs to the technical field of vehicles, and discloses a DPF parking regeneration control method for a hybrid electric vehicle and the vehicle, and the DPF parking regeneration control method for the hybrid electric vehicle comprises the following steps: judging whether the DOC upstream actual temperature reaches the ignition temperature or not; if yes, the engine idles at the set engine rotating speed; if not, whether the vehicle meets the power generation condition or not is judged; if yes, a clutch between the engine and the motor is controlled to be connected, so that the engine can drive the motor to generate electricity; acquiring battery power and actual rotating speed of a motor; according to the ignition temperature, the DOC upstream actual temperature, the battery electric quantity and the actual rotating speed of the motor, the required torque of the motor is obtained; engine demand torque is obtained according to the motor demand torque; the engine operates at a set engine speed and engine demand torque such that the DOC upstream actual temperature reaches the light-off temperature. The DOC upstream actual temperature can reach the ignition temperature in time, and the parking regeneration efficiency is improved.
本发明属于车辆技术领域,公开了混合动力车用DPF驻车再生控制方法及车辆,该混合动力车用DPF驻车再生控制方法,判断DOC上游实际温度是否达到起燃温度;若是,则发动机以设定发动机转速进行空转;若否,则判断车辆是否满足发电条件;若满足,则控制发动机与电机之间的离合器连接,以使发动机能带动电机发电;获取电池电量和电机实际转速;根据起燃温度、DOC上游实际温度、电池电量和电机实际转速,得到电机需求扭矩;根据电机需求扭矩,得到发动机需求扭矩;发动机以设定发动机转速和发动机需求扭矩进行工作,以使DOC上游实际温度达到起燃温度。能使DOC上游实际温度及时达到起燃温度,提高驻车再生的效率。
