Adaptive cruise control

Adaptive cruise control* - function

업데이트됨 7/23/2018

The adaptive cruise control(ACC – Adaptive Cruise Control) helps the driver to maintain an even speed combined with a pre-selected time interval to the vehicle ahead.

It consists of a cruise control system and a coordinated spacing system.

경고

Adaptive cruise control is not a collision avoidance system. The driver must intervene if the system does not detect a vehicle in front.

The adaptive cruise control does not brake for humans or animals, and not for small vehicles such as bicycles and motorcycles. Nor for low trailers, oncoming, slow or stationary vehicles and objects.

Do not use the adaptive cruise control, for example, in city traffic, in dense traffic, at junctions, on slippery surfaces, with a lot of water or slush on the road, in heavy rain/snow, in poor visibility, on winding roads or on slip roads.

Distance to the vehicle ahead is measured primarily by a radar sensor. The cruise control function regulates the speed with acceleration and braking. It is normal for the brakes to emit a low sound when they are being used by the adaptive cruise control.

경고

The brake pedal moves when the adaptive cruise control brakes. Do not rest your foot beneath the brake pedal - it may then become trapped.

The adaptive cruise control aims to follow the vehicle ahead in the same lane according to what the driver set for time interval. If the radar sensor cannot see any vehicle in front then the car will instead maintain the speed set and stored by the driver. This also takes place if the speed of the vehicle in front exceeds the stored speed.

The adaptive cruise control aims to control the speed in a smooth way. In situations that demand sudden braking the driver must brake himself/herself. This applies with large differences in speed, or if the vehicle in front brakes heavily. Due to limitations in the radar sensor braking may come unexpectedly or not at all.

The adaptive cruise control can be activated to follow another vehicle at speeds from 30 km/hQueue Assist (in cars with automatic gearbox) can operate in the range 0-200 km/h. up to 200 km/h. If the speed falls below 30 km/h or if the engine speed becomes too low, the cruise control is set in standby mode at which automatic braking ceases - the driver must then take over himself/herself to maintain a safe distance to the vehicle ahead.

Warning lamp - braking by driver required

Adaptive cruise control has a braking capacity that is equivalent to approx. 40% of the car's braking capacity.

.

If the car needs to be braked more heavily than the adaptive cruise control capacity and the driver does not brake, then the warning lamp and warning sound from the Collision warning system are used in order to alert the driver that immediate intervention is required.

참고

The warning lamp may be difficult to see in strong sunlight or when wearing sunglasses.

경고

The adaptive cruise control only warns of vehicles which its radar unit has detected - hence a warning may not be given, or it may be given with a certain delay. Do not wait for a warning without braking when so required.

Steep roads and/or heavy load

Bear in mind that the adaptive cruise control is primarily intended for use when driving on level road surfaces. It may have difficulty in keeping the correct distance from the vehicle ahead when driving on steep downhill slopes, with a heavy load or with a trailer - in which case, be extra attentive and ready to slow down.
