What Does Car Cruise Control Mean?

1 Answers

Car cruise control is used to maintain a constant speed for the vehicle. Once the car is set to cruise mode, the engine's fuel supply is controlled by the computer, which continuously adjusts the fuel injection based on road conditions and driving resistance to keep the car at the preset speed without the need to operate the throttle. Currently, cruise control systems have become standard equipment in mid-to-high-end cars. Relevant details are as follows: 1. The most obvious advantage of cruise control is that it can free the driver's limbs, significantly reducing fatigue during long-distance steady-speed driving, while also saving excessive fuel consumption caused by frequent speed changes. 2. Cruise control cannot precisely regulate the car's speed. It relies on speed sensors to determine the vehicle's speed and control the throttle. However, during downhill driving, the car may accelerate due to gravitational potential energy. Although the system can continuously adjust based on sensor feedback, the speed may still exceed the set limit during descent.

How to deal with gaps appearing after removing the rear bumper of an Audi Q5?

Check the location and extent of damage on the cracked bumper. Use a single-action sander with 80-grit sandpaper to sand the paint surface at the crack, removing the surface paint coating. Weld the prepared PP welding rod along the crack using a plastic welding gun (hot air gun). Let it dry for a few hours, just wait until the temperature returns to normal. This will repair the crack. Do not spray directly, as this will result in uneven application. Maintain an angle and allow about 15 minutes between each spray, repeating the process five or six times.
