Abstract
A vehicle traction control system that is based on the management of the torque that is produced by the vehicle power train. The actual angular acceleration of a portion of the vehicle drive line is compared to the maximum predicted angular acceleration of the portion of the vehicle drive line to determine the occurrence of a wheel slipping condition. In response to the detection of a wheel slipping condition, the amount of excess drive torque that is being produced by the power train is quantified and the drive torque that is produced by the power train is reduced by an amount which corresponds to the excess. When the slipping condition has been abated, the reduction in the magnitude of the drive torque that is produced by the power train is reduced and eventually eliminated.
