What does cruise mean?

In automobiles, cruise refers to the cruise control system. When a car is driving steadily on the highway, the driver can use this function to maintain the current speed for constant-speed driving. After activating this function, the driver no longer needs to control the accelerator pedal, making it a highly practical feature. How cruise works: The cruise control system operates by having the cruise control module read the pulse signal from the vehicle speed sensor and compare it with the set speed, then issuing commands to the servo mechanism to mechanically adjust the throttle opening, either increasing or decreasing it, to keep the vehicle at the preset speed. Electronic multifunction cruise control eliminates the mechanical control parts of the cable-type cruise control, adopting precise electronic control for more accurate operation and avoiding the risk of mechanical failure. Components of cruise: The cruise control system consists mainly of a control switch, control module (cruise computer), and servo (actuator) in the case of cable-type cruise control. The working principle of the cable-type cruise control system involves the cruise control module reading the pulse signal from the vehicle speed sensor and comparing it with the set speed to adjust the throttle opening, either increasing or decreasing it, to maintain the vehicle at the preset speed. For example, when the vehicle is going uphill and the speed drops, the pulse signal from the speed sensor decreases, and the control module will command the servo actuator to open the throttle to a corresponding angle to maintain speed. Conversely, when going downhill, the throttle opening will be reduced.
In the automotive world, "Cruise" typically refers to the cruise control system. This feature allows me to set a speed on the highway, and the car maintains it automatically. I don't have to keep pressing the accelerator, which significantly reduces driving stress. It's especially great for long trips, like when I drive from Beijing to Shanghai—I just set it to 100 km/h, recline the seat, listen to some music, and the journey becomes much more relaxed. Modern cars even come with adaptive versions that can automatically slow down to avoid vehicles ahead. Another small advantage is that it helps save fuel, as steady-speed driving improves engine efficiency. However, remember not to use it in urban areas or during rain or snow, as changing road conditions make it unsafe. Overall, it's a thoughtful feature worth considering when buying a car.
