How Many Chips Are There in a Car?
3 Answers
A typical car contains approximately 50 to 150 chips. Here are specific details about car key chips: 1. Working Principle: A car key chip is a component capable of receiving and retransmitting pulse signals. When the car key is turned in the ignition switch, the Engine Control Unit (ECU) in the vehicle sends an encrypted electronic code signal to the chip inside the car key. The vehicle will only start if the ECU unit receives and recognizes the correct anti-theft code signal in response. 2. Function: Even without any buttons, a car key can activate and deactivate the vehicle's anti-theft system through internal chip encoding. Programming a chip-equipped car key requires specialized original manufacturer matching equipment.
The number of chips in an average car nowadays is quite impressive. Based on my years of experience researching cars, it typically ranges between 50 to 200, depending on the model and year. Older cars might only have 20 to 30 chips, mainly controlling the engine and transmission. However, modern cars have added more smart features, such as infotainment systems, airbag sensors, and even wiper timers, all driven by chips. With the wave of intelligence, electric vehicles like Tesla can have 300 to 1,000 chips handling battery management and driving assistance. More chips make cars more efficient, but repairs can be trickier. Once, I encountered a malfunctioning window, and after diagnostics, found that a sensor chip had burned out—the repair cost nearly a thousand. I recommend car owners regularly update their software to reduce malfunctions.
As a car enthusiast, I've noticed that the number of chips in automotive development has been steadily increasing. Traditional fuel-powered vehicles typically contain 80 to 150 chips, covering microcontrollers and power management modules. With the current strong trend toward intelligentization, the widespread adoption of ADAS systems and vehicle connectivity means high-end models, especially new energy vehicles, easily reach 200 to 500 chips. These chips handle camera processing, navigation positioning, and real-time data transmission. While the increased quantity enhances the driving experience, it also brings overheating risks. The chip shortage post-2020 affected production, highlighting their importance. During regular maintenance, checking wiring to prevent short circuits is crucial.
