The invention discloses a power acceleration control method for a series-parallel hybrid electric vehicle, which comprises the following steps of: S1, monitoring the acceleration state of a full accelerator of the vehicle so as to obtain the acceleration state data of the vehicle; s2, the maximum wheel end driving torque in the vehicle series connection mode is calculated; s3, the maximum wheel end torque of the vehicle in the parallel connection mode is calculated; s4, predicting the state of the next speed sampling point of the vehicle; and S5, state prediction is carried out on a plurality of subsequent continuous speed sampling points according to the step S4, whether series-parallel connection switching is carried out or not is comprehensively judged based on data of the sampling points, and whether the vehicle needs to adjust an acceleration strategy or not is judged by collecting various kinds of information under the vehicle running state and predicting state information of the vehicle at a plurality of subsequent collecting points. The power acceleration control method of the series-parallel configuration hybrid electric vehicle has the effect of ensuring that the power assembly system of the vehicle can exert the optimal acceleration capability.

    本发明公开了一种串并联构型混动汽车的动力加速控制方法,所述方法包括以下步骤:S1、车辆全油门加速状态监测,以获取车辆加速状态数据;S2、计算车辆串联模式下最大车轮端驱动扭矩;S3、计算车辆并联模式下最大车轮端扭矩;S4、车辆下一速度采样点状态预测;S5、根据步骤S4对后续连续多个速度采样点进行状态预测,并基于多个采样点的数据,综合判断是否进行串并联切换,通过对车辆运行状态下各种信息的采集,并预测车辆在后续多个采集点时的状态信息,以判断车辆是否需要调整加速策略。本发明提供的串并联构型混动汽车的动力加速控制方法具有确保车辆的动力总成系统可以发挥出最优加速能力的效果。
