Advanced Driver Assistance Systems (ADAS) for collision avoidance/mitigation have already demonstrated their benefit on vehicle safety. Often those systems have an additional functionality for comfort to assist the driver in non-critical driving.
The verification of ADAS functionality using different test scenarios is currently investigated in many different projects worldwide. A harmonization of test scenarios and evaluation criteria is not yet accomplished. Often, these test scenarios focus on objective collision avoidance and not on the subjective interaction between driver and vehicle.
The present study deals with the development of an experimental validation plan for the systems Automatic Cruise Control (ACC), Lane Departure Warning (LDW) and Lane Keeping Assist (LKA). Standardized driving maneuvers with two or more vehicles equipped with synchronized measurement are performed by professional test drivers. For this purpose selected public roads are used, and the different maneuvers are conducted avoiding critical situations.
The evaluation is carried out by several different standardized criteria. Subjective evaluations are correlated with objective results from the measurements and analyzed in a specially prepared evaluation sheet.
The present study summarizes the results of this evaluation using different vehicles equipped with relevant ADAS. The results show that there are significant differences in the ADAS behavior which are recognized and evaluated by the drivers. These results are used for future requirements in the vehicle development process.
The limitation of the present study is that the spread in evaluation of professional driver has not yet been investigated and correlated to standard driver behavior.
