Why is Audi q7 cruise not available?

Audi q7 cruise control is not available, usually the speed can't reach the set speed. The Q7 cruise control button is located on the cruise control lever behind the steering wheel. After driving to a certain speed (generally 30 km/h), press the button of the wave head to open it. If you want to release, you can step on the brake or press the button of the wave head to cancel.

Cruise control system is referred to as CCS for short, also known as cruise control device, speed control system, automatic driving system, etc. Its function is to keep the vehicle speed automatically without stepping on the accelerator after the switch is turned on and off at the speed required by the driver, so that the vehicle can run at a fixed speed. With this device, the driver does not need to control the accelerator pedal after driving on the expressway for a long time, thus reducing fatigue, reducing unnecessary speed change and saving fuel.

The working process of constant speed cruise is more intelligent and accurate, that is, the speed is controlled by controlling the signal output by the electronic throttle sensor and adjusting the throttle opening. After the cruise control function is turned on, the cruise control module will accurately calculate the throttle opening through the signal output by the electronic throttle sensor to maintain the current cruise control, make the oil and gas match accurately, reach the driving speed set by the cruise control, and completely abandon the traditional mechanical control, thus achieving the effect of more accurate and safer control.
