摘要 为应对国家日趋严格的油耗限值要求,降低产品油耗,商用车行业开始对自动启停技术开展探索和研究。发动机启停系统的设计需尽可能在动作过程中不改变驾驶员正常的驾驶习惯,通过启停开关打开或关闭启停系统,在系统无故障且具备停机条件时,执行发动机停机,当驾驶员给予请求且满足系统重启条件时,执行发动机重启,发动机启停过程中通过汽车仪表显示系统的工作状态。文章介绍了一种自动启停技术匹配商用车平台的设计方案,自动启停系统的定义及工作状态、逻辑关系、人机界面、启停各状态达成条件及操作要求,并对发动机启停系统停机达成条件、重启达成条件、非驾驶员意愿重启达成条件及系统主要监控故障进行了详细说明,提出部分工作达成条件是商用车特有的,与乘用车存在区别,系统匹配时需特别注意。 In order to meet the increasingly strict fuel consumption limit requirements of the country and reduce the fuel consumption of products, the commercial vehicle industry began to explore and study the automatic start-stop technology. The design of the engine start and stop system shall not change the normal driving habits of the driver during the action as much as possible. The start and stop system shall be opened or closed through the start and stop switch. When the system has no fault and meets the shutdown conditions, the engine shall be stopped. When the driver gives a request and meets the system restart conditions, the engine shall be restarted. During the engine start and stop, the working state of the system shall be displayed through the vehicle instrument.This paper introduces a design scheme of automatic start and stop technology matching the commercial vehicle platform, and introduces in detail the definition, working state, logical relationship, man-machine interface,starting and stopping conditions and operation requirements of the automatic start and stop system.The article also describes in detail the conditions for stopping and restarting the start stop system, the conditions for restarting without the driver’s will and the main monitoring faults of the system. Some working conditions are unique to commercial vehicles, which are different from passenger vehicles,so special attention should be paid to the matching of the system.
