Research on the Lateral Stability Evaluation System for the Motor Vehicle Equipped with ABS by Roadway Test

The ABS lateral stability is principal for the whole vehicle active safety. The present research approaches on this subject are focused on the virtual reality and HiL technology. The test evaluation system for the ABS lateral stability was firstly put forth, which primarily resorted to measure multi--component wheel forces and was enhanced by measuring the trajectory and attitude of the body. This system provides the correlativity between the wheel forces and the kinematical parameters of both wheel and body, and offers the experimental means to assess the ABS brake stability and controllability concretely and generally. Secondly the particular discussion was brought forward for the wheel force transducer and the framework of the test system, then the measurement principle of the body trajectory and attitudes. The following section was attempted to analyze the test procedures for the ABS lateral stability. In the final part of this paper was a brake-in-curve case based on the test of a motor vehicle.
