What is Cruise Control in a Car?
2 Answers
Here is the relevant introduction to cruise control: 1. Cruise control in a car is used to maintain a constant speed. Once the car is set to cruise mode, the engine's fuel supply is controlled by the computer. The computer continuously adjusts the fuel supply based on road conditions and the car's driving resistance to maintain the set speed without the need to operate the throttle. 2. The cruise control system is not suitable for all situations. In principle, cruise control should be used on highways or fully enclosed roads. On non-enclosed roads, complex road conditions can compromise traffic safety. For example, on national highways, some tractors with insufficient power can create obstacles for vehicles using cruise control. Additionally, many small intersections often have vehicles suddenly entering the road, making it difficult to react in time when using cruise control. Repeated braking on national highways also makes it hard to maintain a stable cruise control state, defeating the purpose of cruise control.
I use the cruise control function every day on the highway, it's like finding a substitute for my right foot. As long as the speed exceeds 40 km/h, press the CRUISE button on the steering wheel to activate it, then press SET to lock the current speed, and the car will automatically maintain the throttle without you stepping on it. It's also convenient for following cars in traffic jams - when the car in front slows down, your car will automatically brake. However, don't use it on rainy days or mountain roads, as tire slippage can easily cause accidents. Once I drove 500 kilometers while drinking coffee, and my legs didn't feel sore when I arrived at the destination - it's much less tiring than manual driving. Remember to step on the accelerator to speed up when overtaking, otherwise the system will maintain the original speed.
