What is the function of vehicle sensors?
1 Answers
In automotive electronic control systems, sensors are widely used in various electronic control systems of the engine, chassis, and body. Automotive sensors are responsible for collecting and transmitting information. The electronic control unit processes this information and then issues commands to actuators to implement electronic control. They can promptly identify changes in the external environment and within the system itself, and then control the system's operation based on the changing information. Sensors can be classified into two major categories based on energy relationships: active and passive. Here is an introduction to sensors: 1. Signals: Sensors primarily output two types of signals: analog and digital. Digital signals can be directly input into the electronic control unit, while analog signals need to be converted into digital signals via an A/D converter before being input. The electronic control unit continuously monitors the signals from various sensors. If an abnormal input signal is detected, the erroneous signal is stored in memory. During fault diagnosis and repair, technicians can read fault information using specialized diagnostic tools or manual methods, and then proceed with repairs based on the fault code information. 2. Electronic Control Unit: For the electronic control unit to effectively manage the system's operation, certain conditions must be met. The accuracy, responsiveness, reliability, durability, and output voltage signals of the sensors play a crucial role in ensuring the stability of the system's control.
