If you habitually spend hours at the wheel, you know full well how difficult it can be to keep constant watch of signs, drive in heavy traffic or creep along if there is a tailback. The Travel Assist can help out. When this feature is activated, the car can adjust its speed according to the surrounding traffic and the speed limit, keep the car in lane, and stop and start in a traffic jam.

Lane Assist can tell when you stray from a lane unintentionally. This system works in conjunction with a camera to recognise lane markings on the road, including yellow lines during roadworks, traffic cones, and other roadside or lane borders. The enhanced “Adaptive” variant (only available as part of Travel Assist) means that the system intervenes in an attempt to keep the vehicle in the selected track within the traffic lane, and the car does not “weave”.

A picture processing module searches scanned pictures for known traffic signs and compares the results with the navigation data. The system processes speed limit signs, no-overtaking signs, no-entry signs on one-way streets and any supplementary instructions, as well as associated restriction clearance signs, and then displays them to the driver.

Driver Alert reduces the risk of a fatigue-induced emergency situation. By monitoring driver behaviour, the system assesses the degree of driver fatigue and, if necessary, warns of the need for a rest and break in the journey.
