What is the function of automotive chips?

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.
Having driven for over thirty years, I find that automotive chips have made driving much easier. They manage the air-fuel mixture in the engine to reduce vibrations and improve smoothness. In terms of safety features, the chips monitor wheel speed to prevent skidding during hard braking and help maintain control. Navigation systems use chips for positioning and provide real-time traffic updates to avoid congestion and save time. For battery control, chips optimize the start-stop function, automatically shutting off the engine at red lights to save fuel. In terms of entertainment, the audio system and air conditioning also rely on chips for automatic adjustments to enhance comfort. Additionally, chips detect minor issues like circuit abnormalities, providing early warnings for easier maintenance. They enhance the durability of the car and the convenience of driving, making long trips more enjoyable.
As someone who prioritizes driving safety, I've found that automotive chips are the key guardians. They monitor vehicle speed to trigger electronic stability programs and prevent rollovers. The forward collision warning system relies on chips to analyze distances and activate automatic braking to avoid accidents. Airbag control and tire pressure monitoring also depend on chips for real-time responses to protect passengers. Chips connect with sensors to predict potential hazards like lane departures and alert drivers. These functions can be lifesaving in emergencies, making daily driving safer and more reliable while reducing risks.
