电控汽车主要是通过各种传感器来监测汽车的各种工作状态。传感器将汽车各种状态的物理量,转换成相应的电信号,输送给电控单元(ECU)。ECU综合处理这些信号后,发出控制数据,而执行器接到这些数据后,将其转换成物理或机械动作,以改变汽车的工作状态。如果传感器灵敏度下降,测量误差加大或响应速度变慢,即传感器的工作特性发生变化,则会导致ECU输 Electronic control car is mainly through a variety of sensors to monitor the car’s various working conditions. The sensor converts the physical quantities of various states of the car into corresponding electrical signals and sends them to the ECU. After ECU processes these signals comprehensively, it sends out control data, and after receiving these data, the actuator converts it into physical or mechanical actions to change the working status of the car. If the sensor sensitivity decreases, the measurement error increases or the response speed becomes slower, that is, the sensor’s operating characteristics change, it will lead to ECU lose
