What does ACC mean in automotive circuits?
2 Answers
ACC stands for Adaptive Cruise Control, which is an intelligent automatic control system developed on the basis of existing cruise control technology. During vehicle operation, the distance sensor (radar) installed at the front of the vehicle continuously scans the road ahead, while the wheel speed sensor collects vehicle speed signals. Here is additional information: The function of Adaptive Cruise Control: Based on feedback signals from the distance sensor, the ACC control unit can determine road conditions by assessing the moving speed of nearby objects and control the vehicle's driving state. By sensing the force applied by the driver on the feedback-type accelerator pedal, the ACC control unit can decide whether to execute cruise control to reduce driver fatigue.
ACC in automotive circuits stands for Accessory, known as accessory mode in Chinese. Having driven many cars, when turning the key to this position, devices that don't require the engine to be started can draw power, such as the radio, cigarette lighter, or charging ports. This is quite convenient for playing music while waiting or resting by the roadside without wasting gasoline. It's important to note that leaving ACC on for extended periods can easily drain the battery, especially in older cars where the battery ages quickly. Always remember to turn it off after parking. Many friends overlook this, leading to a dead battery that won't start the engine, causing both trouble and delays in repairs. The ACC switch is usually integrated with the ignition switch, so it's a good habit to check if the car lights are on. For daily driving, knowing the ACC position can enhance comfort, but safety comes first—don't let small devices in the car become major hazards.
