Travel Assist integrates several systems and functions, as presented separately on the following pages. When they are interconnected, the car can make driving a lot easier and increase travelling comfort. Once activated, Travel Assist can automatically stop and restart, keep the car in lane, overtake other vehicles, follow other vehicles in a traffic jam, or show the surrounding traffic on a display in front of you.

Besides keeping track of the traffic ahead, the Predictive Cruise Control also processes recognised travel 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 an intersection, 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.

The car can negotiate narrower lanes (e.g. at traffic construction sites) thanks to Narrow Lane Assist, a further improvement on Adaptive Lane Assist, which keeps the moving vehicle in the chosen position within the lane. The portfolio of situations that can be detected has been expanded to include – besides temporary yellow longitudinal markings – a variety of roadside objects, such as crash barriers and rows of (parallel and perpendicular) parked cars. The car can handle curves without longitudinal markings and navigate narrow city streets. The system only works at speeds above 60 km/h.

Assisted Lane Change can autonomously perform lane changes on motorway-type roads at speeds above 90 km/h. All the driver has to do to start the manoeuvre is switch on the direction indicator (but only in the unlocked position). Assisted Lane Change uses data from a whole range of sensors.

Urban Evasive Steering Support is able to identify common situations in urban traffic, such as parked vehicles, traffic islands, and junctions. It draws on Online Communication data. The assist comes into play in situations when it is impossible to avoid an accident simply by swerving around an obstacle. The system is able to calculate the most appropriate trajectory by drawing on data available from the front camera and radar. This calculation factors in the distance, width and position of the vehicle or obstacle ahead. In a critical situation where Front Assist (see Safety Assists) intervenes by braking and the driver indicates they are taking evasive action by the way they move the steering wheel, Urban Evasive Steering Support makes targeted interventions in the steering to help drive around the obstacle by following an appropriately selected line of travel so as not to collide with the obstacle.

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 their hands on the steering wheel even after a warning alert, Emergency Assist is activated – it brings the car to a standstill while keeping it in lane and activating the hazard warning lights.
