Travel Assist integrates a range of systems and functions to make driving easier and increase travelling comfort. In the Epiq, Travel Assist 3.0 can automatically stop and restart, keep the car in lane, follow other vehicles in traffic, and display surrounding traffic on the display in front of you. Advanced Adaptive Lane Assist supports both longitudinal and lateral guidance across the full speed range. Travel Assist 3.0 can also respond to traffic lights and road signs with automatic stopping, supported by daily online updates of traffic-sign data.

The Predictive Cruise Control expands the Adaptive Cruise Control’s functions. Besides keeping track of the traffic ahead, it 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 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 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”.

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 helps to reduce the risk of an incident if the driver becomes unresponsive. If Adaptive Lane Assist detects that the driver is not holding the steering wheel even after a warning alert, Emergency Assist is activated and can guide the Epiq into a slower lane – or, where possible, the hard shoulder – before bringing the vehicle to a controlled stop.
