Travel Assist integrates several systems and functions, which we present separately on the following pages. When combined, they significantly simplify driving and enhance travel comfort. Once activated, Travel Assist can automatically stop and restart, keep the car in lane, follow other vehicles in a traffic jam, or show the surrounding traffic on a display in front of you.

The Predictive Cruise Control expands the Adaptive Cruise Control’s functions. Besides keeping track of the traffic ahead, it also processes recognised traffic signs and speed limits stored in the navigation system. This enables it to adjust speed in good time, for example when it is approaching a bend, a roundabout, or a junction, or in response to speed limits.

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.

This system works in conjunction with a multifunction 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 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”.

Traffic Jam Assist makes it easier to drive a car in traffic jams. It draws on the Adaptive Cruise Control and Adaptive Lane Assist to start, brake and turn the car to copy the movement of surrounding vehicles in a traffic jam.

Emergency Assist reduces risk of an incident if the driver is not feeling well. If Adaptive Lane Assist detects that the driver does not have hands on the steering wheel even after a warning alert, Emergency Assist is activated, decelerates the car to halt while keeping it in lane and activating the hazard warning lights. eCall, the horn and the interior lights are then automatically activated.
