The embodiment of the invention provides a vehicle drivability evaluation method and system, electronic equipment and a storage medium, and belongs to the technical field of automobile engineering. The method comprises the steps that when it is determined that a vehicle is in a constant acceleration working condition, a vehicle longitudinal acceleration disturbance scoring index, a high-frequency disturbance frequency and amplitude proportion scoring index, a longitudinal acceleration gradient scoring index, an expected acceleration scoring index, an accelerator map matching degree scoring index and a low-frequency resonance scoring index are calculated; based on the vehicle longitudinal acceleration disturbance scoring index, the high-frequency disturbance frequency and amplitude proportion scoring index, the longitudinal acceleration gradient scoring index, the expected acceleration scoring index, the accelerator map matching degree scoring index and the low-frequency resonance scoring index, calculation is conducted according to preset weights, and a drivability evaluation score is obtained. By combining multi-dimensional and quantitative evaluation indexes, accurate evaluation of the acceleration performance of the AMT heavy truck is realized, the evaluation consistency and efficiency are improved, and the evaluation cost is reduced.

    本发明实施例提供一种车辆的驾驶性能评价方法、系统、电子设备及存储介质,属于汽车工程技术领域。该方法包括:确定车辆处于恒定加速工况时,分别计算车辆纵向加速度扰动评分指标、高频扰动的频率和振幅占比评分指标、纵向加速度梯度评分指标、期望加速度评分指标、油门map匹配度评分指标及低频共振评分指标;基于车辆纵向加速度扰动评分指标、高频扰动的频率和振幅占比评分指标、纵向加速度梯度评分指标、期望加速度评分指标、油门map匹配度评分指标以及低频共振评分指标按照预设的权重进行计算,得到驾驶性能评价得分。通过结合多维度、量化的评价指标,实现对AMT重型汽车加速性能的准确评价,提升评价的一致性和效率,降低评价成本。
