摘要： 针对混动车型在怠速充电工况发动机启机过程中产生的车身及座椅振动冲击问题，文 章基于振动冲击产生机理、激励源分析和气缸压力相位分析技术，系统研究了启机冲击特性 及产生的根本原因。研究结果表明，启机冲击现象主要由第一压缩压力峰值大导致，较大的 压缩压力引起转速波动偏大，激发起动力总成及整车的晃动。据此，提出了基于 P1 电机转角 控制功能的最优初始相位控制方法，实车验证效果显著。该研究为混动车怠速启机噪声、振 动与声振粗糙度（NVH）开发提供了极具价值的理论及实践参考。

Abstract: Based on the vibration impact on vehicle body and seat induced by engine start-up under idle start-up condition in hybrid electric vehicles, this paper systematically investigates the start-up impact characteristics and its root causes through jitter generation mechanism analysis, excitation source analysis and cylinder pressure phase analysis technology. The research results indicate that the start-up jitter is mainly attributed to the large peak value of the first compression pressure. The larger compression pressure causes excessive speed fluctuation, which excites the shake of the power train and the whole vehicle. Accordingly, an optimal initial phase control method based on the crank angle control of P1 motor is proposed, and remarkable effect is achieved via real vehicle verification. This study provides valuable theoretical and practical reference for the noise, vibration, harshness (NVH) development of idle start-up for hybrid electric vehicles.
