Abstract

A truck has improved control with a plurality of wheels each having a single wheel drive and a device for controlling speed and/or torque of the single wheel drives. The control device has a separate controller train for each wheel drive, with each controller train having a differential controller for correcting divided torque depending on steering angle and a wheel slip controller correcting the divided torque or torque value corrected by the differential controller depending on wheel slip and providing a corresponding single wheel drive torque value.
