Does the cruise control turn off when the brake is pressed?
2 Answers
When the brake is pressed, the cruise control will automatically turn off. Here is some relevant information: Cruise Control: The Cruise Control System (CRUISE-CONTROL-SYSTEM), abbreviated as CCS, is also known as a speed control device or autonomous driving system. Its function is to automatically maintain the vehicle's speed as set by the driver without the need to press the accelerator pedal, allowing the vehicle to travel at a fixed speed. Working Principle: In simple terms, the cruise control system works by the cruise control component reading the pulse signal from the speed sensor and comparing it with the set speed, then issuing commands to the servo mechanism to adjust the throttle opening to increase or decrease, ensuring the vehicle maintains the set speed.
During a long-distance drive using cruise control, I clearly felt the vehicle exit the automatic cruise state when I stepped on the brake. This is actually an essential safety mechanism for cars, and almost all vehicles equipped with cruise control are designed this way. Pressing the brake sends a signal to the computer, immediately cutting off the cruise system and returning the car to manual driving mode. This design is very reasonable—imagine if there’s a sudden car ahead or you need to slow down at an intersection; it would be dangerous if the brake didn’t deactivate the cruise. After deactivation, the dashboard usually shows a change in indicator lights, and you need to reset the speed to re-engage the system. Additionally, it’s worth noting that some models may have a similar function with the handbrake, but it’s not recommended. The most reliable method is still using the brake to deactivate cruise control.
