Volvo’s appropriately named Pilot Assist’ accurately portrays system functionality. The promotional material and the handbook correctly indicate the limitations of the system capabilities. System status information is clearly displayed but there is no head-up display in the EC40. The sensing of hands on the steering wheel was not robust, and the system lost points in this area. The system balances driver steering input with lane guidance, promoting co-operative driving.

The EC40 combines map-based speed limit information with real time camera inputs to manage fixed, variable and temporary speed limit signs but does not adapt speed for upcoming road features such as curves and junctions. The EC40 responds to avoid or mitigate a collision in many of the ACC test scenarios. The driver is supported through the S-Bend, but the car is kept fully in lane only at the lowest test speed. A lane-change assist function is not provided. In case of an unresponsive driver, the Volvo performs a controlled stop within lane. If the radar or camera is blocked the car provides a timely warning and prevents system activation.

The EC40 from Volvo provides good Vehicle Assistance with a similar level of Driver Engagement. Combined with a high level safety back-up, the system, overall, offers Good highway assistance.
