Abstract: The improvement of vehicle dynamic responsiveness is conducive to the improvement of power level, and is one of the important indicators to improve consumers' driving experience. Some models have sufficient power but poor power response, which seriously affects the driving experience of consumers. Starting from the actual driving scenario with high responsiveness demand of consumers, this paper designed six test conditions for a hybrid electric vehicle, including creep start, in place start, dynamic start, rapid acceleration, kick down downshift and mode switching, and formulated seven responsiveness evaluation indexes and corresponding analysis methods, including creep start response time and in place start response time. From the perspective of consumers' actual use, this paper put forward the responsive indicators that should be paid attention to in the process of dynamic development, so as to improve consumers' satisfaction with the brand. The analysis results show that the dynamic responsiveness of hybrid electric vehicles is affected by the vehicle performance adjustment and power source matching strategy, and the control strategy of releasing the required torque as soon as possible is conducive to the improvement of responsiveness.
