What is the function of automotive chips?
2 Answers
When the car key is turned in the ignition switch, the engine control unit (ECU) in the car sends a set of encrypted electronic code signals to the chip inside the car key. The vehicle will only start if the ECU unit can read and receive the correct anti-theft coded signal in response. Therefore, even a simple car key without any buttons can activate and deactivate the vehicle's anti-theft system through the internal chip encoding. Here is more related information: Function of the chip: Car keys with chips require special, dedicated original factory matching equipment for programming. In the automotive field, the chip is referred to as a magnetically coupled transponder system. The magnetically coupled transponder system is essentially passive. The chip itself does not require a constant power supply, thus eliminating the need for continuous power. It only needs to operate within the electromagnetic wave range of 125kHz frequency. Under the electromagnetic waves, the chip generates the originally set coded signal, typically within a range of 1 cm to 15 cm. Since this is a radio frequency, it can penetrate materials, allowing the chip to be concealed and shaped into a key head made of plastic or rubber. The working principle of key identification in most car anti-theft system chips is fundamentally similar. When a car chip key is inserted into the ignition lock and turned to the "on" or "run" position, the induction coil installed around the ignition lock sends out an electromagnetic wave. The electromagnetic wave radiates through the winding in the key chip, powering the electronic chip to generate the coded signal.
Since childhood, I've been fascinated by technology. Automotive chips are like the brain of a car, handling various critical tasks. They process engine control signals, such as adjusting fuel injection and ignition timing, to optimize performance. In terms of safety and driver assistance, these chips analyze sensor data to enable features like anti-lock braking or adaptive cruise control, maintaining safe distances to prevent collisions. For electric and hybrid systems, chips manage battery charge-discharge balance and regenerative braking energy recovery. On the entertainment side, infotainment screens and navigation rely on chips for rapid route calculations and music playback. These chips also connect vehicles to the cloud, enabling remote diagnostics and over-the-air software updates to enhance functionality. In short, these chips make modern vehicles intelligent, reliable, and safe.
