The embodiment of the invention provides a hundred-kilometer acceleration control method of a hybrid electric vehicle and the hybrid electric vehicle, and the control method comprises the steps: obtaining starting information of hundred-kilometer acceleration; the peak power P1 of the generator, the peak power P2 of the driving motor and the real-time required power P0 of the whole vehicle are obtained; acquiring the output power Psoc of the battery in the current state of charge; comparing the size of P1 + P2 with the size of Psoc; if Psoc is greater than or equal to P1 + P2, comparing P1 + P2 with P0; and according to the comparison result of P1 + P2 and P0, the start-stop state of the engine is controlled. According to the control method, the peak power P1 of the generator and the peak power P2 of the driving motor are introduced into control over the engine, the output capacity of the generator and the output capacity of the driving motor can be more accurately judged in real time in the hundred-kilometer acceleration process of the whole vehicle, and when the generator and the driving motor cannot meet the power requirement for hundred-kilometer acceleration, the output capacity of the generator and the output capacity of the driving motor can be accurately judged in real time. And the engine can be started in time, so that the acceleration time per hundred kilometers is shortened.
本申请实施例提供了一种混合动力汽车的百公里加速的控制方法及混合动力汽车,其中,控制方法包括:获取到百公里加速的启动信息;获取所述发电机的峰值功率P1、所述驱动电机的峰值功率P2及整车的实时需求功率P0;获取所述电池处于当前荷电状态下的输出功率Psoc;比较P1+P2与Psoc的大小;若Psoc≥P1+P2,则比较P1+P2与P0的大小;根据P1+P2与P0的比较结果,控制所述发动机的启停状态。本申请实施例的控制方法,将发电机的峰值功率P1及驱动电机的峰值功率P2引入发动机的控制,整车在百公里加速过程中,能够实时并且更为精确地判断发电机和驱动电机的输出能力,在发电机与驱动电机无法满足百公里加速的功率需求时,发动机能够及时启动,由此,缩短了百公里加速时间。
