Abstract: A method for the distribution of drive torque to the wheels of a driven axle of a motor vehicle. The bend slip between a bend-inside and a bend-outside wheel of an axle of the motor vehicle during cornering is calculated. The inner drive slip between the bend-inside driven wheel and the bend-inside nondriven wheel is calculated. The drive torque is distributed as a function of a difference between the inner drive slip and the bend slip, multiplied by a scaling factor.

Abstract: A vehicle steering system having a steering handle for steering at least one wheel is provided, and includes an arrangement for applying torque to the steering handle and a sensor for detecting applied steering torque. The arrangement generates a return torque, as a function of the steering angle, for driving the steering handle into a central position. During a first driving state in which applied steering torque is above a threshold value, the function curve of the return torque increases monotonically and no return torque is generated at a steering angle of zero. During a second driving state in which applied steering torque is below the threshold value, the arrangement generates a return torque that is greater than that given by the function curve in the first driving state, at least at small steering angles.

Abstract: A motor-driven power steering unit comprising an electric motor for producing an auxiliary steering force in a steering system coupling a steering wheel to two wheels of a vehicle. The steering system provides assistance, based on steering information, to a rotation of the steering wheel by control of an electric current fed to the electric motor. A steering angle detection device is provided, wherein the steering system regulates the assistance as a function of a steering angle detected by the detection device. The assistance, or current, is reduced after a pre-set or pre-definable angle is reached or exceeded prior to reaching a respective end position. The reduction of the assistance or current is cancelled as soon as signs of steering force and the steering angel no longer coincide.
