Diagnostic circuit for traction bias on motor vehicle braking or acceleration, has computers to produce mean data values from wheels for comparison to set values

摘要

The diagnostic circuit for motor vehicle braking or acceleration traction bias has a computer (20) to determine the first values associated with each wheel or brake. A computer (21) associated with at least one axle of the vehicle calculates a second value as a measure of the deviation of the first values at the axle. A calculator determines a mean value and a comparator compares this value to a preset value. The deviation of the mean data can be measured over time. Claims include a method of controlling wheel patter using the circuit.
