Mercedes-Benz’s appropriately named ‘Active Distance Assist DISTRONIC’ accurately portrays system functionality. The promotional material and the handbook correctly indicate the limitations of the system capabilities. System status information is clearly displayed in the driver’s direct line of sight by a head-up display. The Mercedes-Benz has an internal camera to check for ‘microsleep’ and combines this information with steering wheel input to monitor driver status. The system balances driver steering input with lane guidance, promoting co-operative driving.

The EQE SUV combines map-based speed limit information with real time camera inputs to manage fixed, variable and temporary speed limit signs. The system adapts speed for upcoming road features such as curves and junctions. The EQE SUV responds to avoid a collision in most of the ACC test scenarios. The driver is supported through the S-Bend, staying within the lane at all test speeds. The vehicle has an Active Blindspot system designed to prevent lane changing into adjacent vehicles. A lane-change assist function is provided. In case of an unresponsive driver, the EQE SUV automatically moves to the slowest lane and performs a controlled stop. If the radar or camera is blocked the EQE SUV provides a timely warning and prevents system activation.

The EQE SUV from Mercedes-EQ provides very good Vehicle Assistance with a similar level of Driver Engagement. Combined with excellent safety back-up, the system, overall, offers Very Good highway assistance.
