Wheel-Individual Estimation of the Friction Potential for Split Friction and Changing Friction Conditions for the Application in an Automated Emergency Braking System

Including information of the current road surface conditions can significantly improve the effectiveness of an AEB (automated emergency braking) system to avoid accidents or reduce the injury severity in rear-end crashes. A method to estimate the friction potential based on on-board sensor information is shown in this work. This work expands the scope of existing investigations on whether the accuracy needed for the warning and intervention strategies of AEB can be reached with the proposed method. First, the bandwidth of surface conditions investigated is extended by including low friction surfaces comparable to ice. Second, situations of changing surface conditions and wheel-individual surface conditions were evaluated. Finally, estimation based on different sensor sets was conducted with regard to series application. The investigations are based on measurements performed on a proving ground. The main emphasis was placed on estimation during longitudinal driving conditions. The used sensors include advanced vehicle dynamics measurement equipment as well as standard on-board sensors of the vehicle.

Intelligent cars

The intelligent car initiative is designed to promote the use of new technologies to make cars safer, cleaner and more efficient. The various technologies like automatic emergency braking system, pedestrian safety, driver support, predictive cruise control, intelligent transportation system, integrated safety management etc. developed by the different car makers like Volvo, Mercedes, Tyota and GM motors ensure to provide a better and safe drive in the coming future. Also the use of various type of indicating devices used at the highways reduces the chance of any collision.

Forecasting the gain in safety afforded by accident avoidance systems

Within a dissertation a method was developed that allows predicting the safety benefit of selected assistance systems. This article by Volkswagen and the company Verkehrsunfallforschung GmbH, Dresden, Germany, describes the methodology, the used software and its modules, and it shows the results attained when examining a brake assist system and an automatic emergency braking system.
