Abstract

Vehicle roll angle is one of the most important values for lateral vehicle dynamics. Electronic lateral dynamic control system operates only as desired during all driving maneuvers on all road surfaces, if the vehicle roll angle is known. Due to economical reasons, the vehicle roll angle is not measurable in series-produced vehicles. Not only more precision of vehicle roll angle estimation, but also evaluation of estimation error are demanded by automobile industry. In this contribution a new concept, which allows a specification of the estimated angle statistically, is presented. The performance of this concept is tested by car tests.
