The invention discloses a preheating method of a hybrid power vehicle and the hybrid power vehicle adopting the preheating method, and the preheating method comprises the steps that the state of the vehicle is obtained; judging whether the vehicle meets a vehicle heating condition or not according to the state of the vehicle; if yes, the clutch is controlled to be combined, and the load is powered on; obtaining a vehicle demand; and controlling the engine to work at a first rotating speed in a non-idling state according to vehicle requirements, controlling the motor to generate electricity at a first torque, and heating the power battery through the heater. Therefore, on one hand, emission during vehicle heating can be improved; on the other hand, in the vehicle heating process, the engine drives the motor to generate electricity, the electricity can be supplied to the load, the power battery is heated through the heater, the working environment of the power battery is improved, energy during vehicle heating can be utilized, energy consumption is reduced, the working environment of the battery pack is more suitable, and the service life of the battery pack is prolonged. The charging and discharging performance of the battery pack can be improved, and a vehicle can be preheated more quickly.

    本申请公开了一种混合动力车辆的预热方法以及采用其的混合动力车辆,所述预热方法,包括:获取车辆的状态;根据车辆的状态判断车辆是否符合热车条件;如果符合,则控制离合器结合,负载上电;获取车辆需求;根据车辆需求控制发动机以非怠速状态的第一转速工作,控制电机以第一扭矩发电,并通过加热器对动力电池进行加热。由此,一方面,可以改善热车时的排放;另一方面,热车过程中,发动机驱动电机进行发电,发电可以为负载供电,并通过加热器对动力电池进行加热,改善动力电池的工作环境,不仅可以热车时的能量利用了,以降低能耗,而且使电池包的工作环境更加适宜,可以提高电池包的充放电性能,使车辆可以更快的预热完毕。
