汽车的电子控制系统是指汽车的所有工况(发动机和底盘)都在电子控制装置的监控下运行,使汽车处于最佳运行状态,可靠性大大提高,因故障而停车的概率下降。汽车电子控制系统是由复杂精密的电子元器件、集成电路和自动执行装置组成,并且越来越多地使用计算机集成控制系统,这些产品对使用环境的要求较高,尤其对温度、湿度和电源系统电压的稳定性要求更加严格。使用中如不注意这些问题,稍有失误就会人为地造成系统的破坏,还会引发灾难性后果。因此,汽车维修人员不但要系统全面地掌握整个系统的结构原理和电气线路,而且要掌握基本的检修方法。在对电控车辆进行检修时,切不可随意乱动。维修人员和驾驶员应注意以下几个方面的问题:
The electronic control system of the car means that all the operating conditions of the car (engine and chassis) are under the control of the electronic control device, so that the car is in the best running state, the reliability is greatly improved and the probability of parking due to the fault is reduced. Automotive electronic control system is composed of sophisticated electronic components, integrated circuits and automatic execution device, and more and more use of computer integrated control system, these products require a higher use of the environment, especially for temperature, humidity and power System voltage stability requirements more stringent. If you do not pay attention to these issues in use, a slight mistake will artificially cause system damage, but also lead to catastrophic consequences. Therefore, the car maintenance staff not only systematically grasp the entire system structure principle and electrical wiring, but also to master the basic maintenance methods. In the electric vehicle maintenance, must not be free to move. Maintenance personnel and drivers should pay attention to the following aspects:
