METHOD AND DEVICE FOR DETECTING A BAD ROAD FOR AUTOMOBILE

摘要

The invention relates to a method for detecting a bad road condition for an automobile provided with an electronic central unit and four wheel rotation speed sensors, characterised in that it analyses the amplitude of the high frequency noise in the signals from the four wheel speed sensors and detects the number of crossings by the maximum noise value for the four wheel set of a threshold parametered for a predetermined duration and in the absence of a wheel slippage.
