Project Objective

The objective of the FRICTI@N project is to create an on-board system for estimating friction and road slipperiness to enhance the performance of integrated and cooperative safety systems like vehicle-to-vehicle communication, and driver information. Moreover, applications that can benefit from precise information on road slipperiness are driving safety control systems such as Slip Control Systems, Emergency Braking System, Electronic Stability Program, Adaptive Cruise Control and Roll-over Avoidance. It seems evident that a single sensor approach is not successful in determining road friction with a sufficient accuracy to improve vehicle control. The project will not develop new sensors, but uses existing ones in a novel way. The aim is a solution for real-time estimation of the tyre-road friction using a sensor cluster in a moving vehicle. Consequently, three kinds of sensors will be used: (i) existing in-vehicle sensors for vehicle dynamics, (ii) environmental sensors, and (iii) tyre-based sensors. Today, the signals from these sensors are used separately for vehicle safety systems without combining them. The project has two characteristics: vertical in developing a new system to enhance driver assistance, and horizontal in providing a system for different applications and for on-going projects in preventive safety and upcoming cooperative systems. The innovative idea is to feed the signals into a FRICTI@N-Estimation-Observer to estimate the tyre-road friction by using on-line mathematical methods. The consortium is strong in the proposed field comprising of 10 partners from automotive and supplier industries including one SME and three research institutes. The FRICTI@N project supports the eSafety initiative for the development, deployment and use of Intelligent Integrated Safety Systems in Europe.
