What do res and set mean respectively?
1 Answers
res and set are the resume key and set speed key respectively, commonly found on a car's cruise control system. The working principle of cruise control is: the cruise control component 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 to increase or decrease, ensuring the vehicle maintains the set speed. The method of using cruise control is: 1. Press the cruise control button; 2. After activation, when reaching the desired speed, press the set button; 3. To decrease the cruise speed, press the set minus button; 4. To increase the cruise speed, press res; 5. To temporarily deactivate the cruise control system, press the brake pedal or the button.
