The invention provides a vehicle drivability debugging method and system, and the method comprises the steps: controlling a hybrid system in a vehicle to correspondingly enter a parallel working condition when the vehicle is detected to be in a normal driving state in real time; when it is detected that the driving power of a driving motor in the vehicle is smaller than a preset power threshold value in real time, a parallel single power source mode of the hybrid power system is activated; acquiring running parameters correspondingly generated by the vehicle in the parallel single power source mode in real time, and analyzing the running state of the vehicle in real time according to the running parameters; and calibrating a clutch, a gearbox and an engine in the vehicle according to a data analysis result, and testing the driving performance of the vehicle according to the performance of a driving wheel end of the engine in real time. Multi-power-source cooperative control of the whole vehicle system can be controlled, the whole vehicle driving problem is quickly positioned, a software calibration test scheme is formulated, and the whole vehicle driving feeling is improved.

    本发明提供了一种车辆驾驶性调试方法及系统,该方法包括:当实时检测到车辆处于正常行驶状态时,控制所述车辆内部的混动系统对应进入并联工况;当实时检测到所述车辆内部的驱动电机的驱动功率小于预设功率阈值时,激活所述混动系统的并联单动力源模式;实时采集所述车辆在所述并联单动力源模式下对应产生的行驶参数,并根据所述行驶参数实时分析所述车辆行驶状态;根据数据分析结果对所述车辆内部的离合器、变速箱以及发动机进行标定,并实时根据所述发动机的驱动轮端表现测试所述车辆的驾驶性能。本发明能够控制整车系统多动力源协同控制,快速定位整车驾驶问题,制定软件标定测试方案,提升整车驾驶感受。
