摘　　要：本文介绍了增程式混合动力客车发电控制策略及其控制逻辑对发动机超速问题的影响,分析了引发发动机超速的各种因素,最终确定为整车控制策略存在缺陷,导致发动机受控逻辑缺乏匹配。针对问题提出优化整车控制策略和控制逻辑方案,实现对发动机超速的有效控制。This paper introduces the power generation control strategy of the extended-range hybrid bus and the influence of its control logic on the engine overspeed problem,analyzes the various factors that cause the engine overspeed,and finally determines that the vehicle control strategy is defective,resulting in the lack of matching of the engine control logic.In view of the problem,the optimized vehicle control strategy and control logic scheme were proposed to achieve effective control of engine overspeed.
