Roll Over Prevention Based on State-of-the-Art ABS Systems 2001-01-2727

The benefits of roll over prevention (ROP) or even roll over warning systems are obvious: besides potentially saving human lives, goods and vehicles they may save on insurance costs and help educate drivers and promote better driving habits. Various brake system manufacturers offer several ROP systems, but they are all common in one respect, namely that they are hosted by an Electronic Braking System (EBS) system. In general, based on sensory observation, the danger of a particular situation is judged by a central ECU and if necessary, brakes are actuated individually, independent of the driver’s intention, to improve the vehicle’s stability. Although the feature is very attractive, the market seems slow to accept new technologies, particularly in view of the additional price overhead of EBS compared to current ABS braking systems. A better short term low cost solution is to realize an ROP algorithm on common ABS systems for trailers.
