What does cruise mean on the dashboard?

cruise on the dashboard refers to the electronic cruise control system, which mainly consists of four parts: the command switch, sensors, cruise control system ECU, and throttle actuator. Only automatic transmission vehicles have the cruise function, which allows the car to drive automatically at a preset speed. The car cruise system is controlled by the onboard computer, which obtains data through three sensors: wheel sensors, geomagnetic sensors, and yaw sensors to determine the car's speed and position. The cruise system works by the cruise control component reading the pulse signal from the speed sensor, comparing it with the set speed, and then issuing commands to the servo mechanism to adjust the throttle opening to increase or decrease, so that the vehicle always maintains the set speed.
I've been driving for many years, and the 'cruise' on the dashboard represents the cruise control system. When you press the set button on the steering wheel, the speed gets locked, and the cruise indicator light turns on. This means the system is automatically controlling the speed, so you don't have to keep pressing the accelerator, which feels quite relaxing, especially during long highway drives where your legs don't get tired. I often find that using this feature can save some fuel because the throttle is more stable, maintaining a constant speed. However, be cautious in complex conditions like rain, snow, or heavy traffic, and turn it off to avoid delayed reactions. Sometimes, the system may malfunction—if the indicator light flashes, it's time to get it checked and fixed to prevent issues. Beginners should practice operating it in empty areas to get used to the controls.
I understand the principle of cars. When the 'cruise' light on the dashboard is on, it indicates that the cruise control is active, and the throttle is being controlled by the ECU to maintain the set speed. Simply put, you set a speed value, such as sixty kilometers per hour, and the system adjusts the fuel injection based on sensor inputs to maintain a constant speed. It works best on open roads, slightly increasing fuel on uphill slopes and reducing it downhill to save effort. I like this feature because it's precise and fuel-efficient, but be careful not to use it on slippery roads to avoid losing control. Regular maintenance to check sensors and wiring ensures they don't deteriorate, which is beneficial for safe driving.
