摘　　要：主要论述了电控柴油机中巡航控制的软件开发及试验研究。当满足巡航要求进入巡航状态时,巡航控制采用闭环的PID控制方式,通过转速差调整虚拟踏板大小进而调整油量大小,最终实现恒定车速的目标。试验验证的结果表明,巡航控制中巡航锁定、巡航减速、巡航加速以及超车等功能控制完善、可靠,在保证安全性以及稳定性的前提下较好地实现了巡航控制功能。The paper discusses software development and test study of cruise control system.Entering cruise control conditions include affirming external control button and judging of accelerate pedal and brake clutch and roadway situation.When meeting all the conditions,it can realize stable vehicle speed by PID closed loop control manner.The test result indicates control function is perfect and credibility in cruise locking,cruise deceleration,cruise acceleration and overtake,and which can better realized the cruise control function on the premise that the safety and stability of the vehicle can be ensured.
