What is the cancel button on a car?
1 Answers
On a car, the cancel button is used to deactivate the cruise control. The cruise control system, also known as speed control, automatic driving system, etc., will temporarily stop cruising when the cancel button is pressed during cruise operation, and the cruise set indicator light on the temperature gauge will turn off. The principle of cruise control is that the cruise control unit reads the pulse signal from the speed sensor and compares it with the set speed, then issues commands to the servo mechanism to adjust the throttle opening, increasing or decreasing it to maintain the set speed. This helps reduce driver fatigue, minimizes unnecessary speed variations, and saves fuel.
