SYSTEM AND METHOD FOR TRACKING THE PATH OF A VEHICLE

摘要

The invention relates to a system for tracking the path of a motor vehicle (1), said system comprising an instantaneous speed sensor on each wheel (6, 9) of the front and rear axle systems. According to the invention, the system comprises a means (200 and 201) for calculating the speed loss between wheels of a single axle system (?av and ?ar), a means (202) for calculating the difference between the speed losses of each axle system, and a means (203) for comparing said difference with a stored threshold value (e). The invention also relates to a method for tracking the path of a motor vehicle, said method including the following steps: calculating the speed losses for the wheels of the front and rear axle systems (?av and ?ar), calculating the speed loss difference between each front and rear axle system (?av and ?ar), and comparing the speed loss difference with a stored threshold value (e).
