<p>The present invention relates to a truck, in particular to a bulk goods dump truck of the so-called large dump truck type, having a chassis with wheels of which a plurality of wheels each have a single wheel drive and having a control device for the control of the speed and/or of the torque of the single wheel drives. In order also to be able to operate the vehicle in the optimal wheel slip range under difficult ground conditions, provision is made for the control device to have a separate controller train for each single wheel drive and to divide a desired torque set by the operator to the controller trains, with each controller train having a differential controller which corrects the divided desired torque in dependence on a steering angle and provides a correspondingly corrected desired torque as well as having a wheel slip controller which corrects the divided desired torque or the desired torque value corrected by the differential controller in dependence on its wheel slip and provides a corresponding single wheel drive desired torque value. A simple expansion to more than two drives is possible by the provision of separate control trains. In this connection, the desired torque is first divided to the single drives by the operator, then corrected by the differential control and the wheel slip control and finally transmitted to a frequency inverter as a desired torque.</p> |
