Motor vehicle braking and road holding control - automatically switches device in and out when measured road friction reaches threshold

摘要

A controller for a vehicle braking and tracking maintenance device contains a road friction measurement controlled consisting of a friction measurement wheel generator (1), a control generator (9), transfer lines (2), a control stator (3), a control slider (4) and a hydraulic, pneumatic, electrical or mechanical triggering switch (11). The friction measurement wheel generator is pivotably or displaceably mounted on a vehicle axle and is held in sprung contact with the road surface when in the operating position. USE/ADVANTAGE - Automatic switching in and out of a braking and tracking maintenance device when road friction reaches a defined threshold, i.e. counteracting aquaplaning or slipping on ice.
