摘 要 驾驶汽车长途行驶的机会较多，在高速公路上长时间行驶时，打开该系统的自动操纵开关后，巡航控制系统将根据行车阻力自动增减节气门开度，使汽车行驶速度保持一定的。并且可以避免驾驶员频繁踩油门踏板，而保证汽车以预先设定的速度行驶。汽车在一定条件下恒速行驶，大大地减轻了驾驶员的疲劳强度。由于巡航控制系统能自动地维持车速，避免了不必要的油门踏板的人为变动，进而改善了汽车的燃料经济性和发动机的排放性。 汽车电子化程度也越来越高，特别是微处理器进入汽车控制领域后，给汽车发展带来了划时代的变化。汽车自动巡航控制系统（CRUISE CONTROL SYSTEM）就是其中一个改变原始驾驶理念的新技术。汽车巡航控制系统的出现能为驾驶员提供更加舒适的驾驶环境。巡航控制系统不仅在长时间行车时能够减轻驾驶员的疲劳程度，同时减少了不必要的车速变化，提高了乘坐的舒适性，还可以节省燃料和减少废气排放，提高经济性。提高汽车行驶时的舒适性，特别使在郊外或高速公路上行驶，这种优越性更为显著。另外，当汽车以一定速度行驶时，减少了驾驶员的负担，使其可以轻松地驾驶。 保持汽车车速的稳定，汽车无论是在上坡、下破、平路上行驶，或是在风速变化的情况下行驶，只要在发动机功率允许的范围内，汽车的行驶速度保持不变。 总的来说，汽车巡航控制系统主要功能有巡航定速、巡航加速、巡航减速等功能。 关键字： 巡航控制系统；保持恒速； 巡航减速； 恢复原速 Automobile cruise electronic control system Abstract As the auto industy and toad transport sector development ,the automation of vehicles driving cars has become one of the major trends in development .people need to be more comfortable,convenient and safe means of transport to meet the fast pace of life.So the request of intelligent become more urgent. With the development of electronic,our life changing so fast.In order to meet peole’s needs,automotive electronics become more and more high-lieve.In particular the microprocessor enter the field of automotive control,the car has bought to the epoch-making change. Automobile cruise electronic control system can provide a comfortable citcumstance for dirvers.In one hand ,it lenlify the job when driving but improve comfort.When the car in the long-distance highway driving,automobile cruise control system can automatically fixed at a specific rate ,from motorists to foot pedal long bitterness.At the same time,it can cruise in the state scheduled for the speed acceleration and deceleration of the regulation..In assition ,the cruise control system also save fuel and resuce disuse. In the 1960s of the USA,the cruise control system has been used in cars widely. Nowday many cars fix the cruise control system. Japanese and European cars are equipped with the production of cruise control system. Because of our the late of develo
