Abstract:
1. A traction control method for a vehicle of the type having a driven wheel with an associated wheel brake, a drive engine, and an electronic controller with a first linear sub-controller and a second linear sub-controller, the method comprising the steps of: determining at least one wheel-specific characteristic; from the at least one wheel-specific characteristic, generating in the first linear sub-controller a first suggested output control variable in accordance with a first model driving condition, the first suggested output control variable comprising a first suggested brake output control variable for the wheel brake associated with the driven wheel and a first suggested engine output control variable for the drive engine, from the at least one wheel-specific characteristic, generating in the second linear sub-controller a second suggested output control variable in accordance with a second model driving condition, the second suggested output variable comprising a second suggested brake output control variable for the wheel brake associated with the driven wheel and a second suggested engine output control variable for the drive engine, carrying out a weighted addition of the first and second suggested output control variables based on actual driving conditions to calculate a combined output control variable comprising a combined brake output control variable and a combined engine brake control variable, controlling the wheel brake of the driven wheel according to the combined brake output control variable and the drive engine in according to the combined engine output control variable.
