Abstract
The invention relates to a method for assisting an operator of a vehicle in adjusting a nominal steering angle at steerable wheels of the vehicle for the vehicle stabilization, in which an additional steering torque is applied to the steering line of the vehicle, which is determined dependent on a difference between a nominal steering angle and an instantaneous steering angle.
The method is characterized in that a value of a load moment acting on the steering line of the vehicle is estimated, and that the additional steering torque is established dependent on the estimated value for the load moment.
In addition, the invention relates to a device appropriate to implement the method.

18. A method for assisting an operator of a vehicle in adjusting a nominal steering angle at steerable wheels of the vehicle for vehicle stabilization, the method comprising:
-
determining a steering line of the vehicle dependent on a difference between a nominal steering angle and an instantaneous steering angle; estimating a value of a load moment acting on the steering line of the vehicle; and applying an additional torque to the determined steering line of the vehicle, wherein the additional steering torque is established dependent on the estimated value for the load moment. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)

26. A device for assisting an operator of a vehicle in adjusting a nominal steering angle on at least one steerable wheel of the vehicle for vehicle stabilization, the device comprising:
-
a control unit for determining a deviation between a nominal steering angle and an instantaneous steering angle of the vehicle; a torque adjusting device that adjusts an additional steering torque, wherein the additional steering torque is determined based on deviation between the nominal steering angle and the instantaneous steering angle; one or more sensors mounted in the steering line of the motor vehicle; an estimation device for estimating a load moment that acts on the steering line based on signals from the one or more sensors mounted in the steering line of the motor vehicle; a device for establishing at least one component of the additional steering torque for the estimated load moment; and an adder for adding the additional steering torque to the steering torque established by the deviation between the nominal steering angle and the instantaneous steering angle, wherein the torque adjusting device is driven by an output of the adder. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34)
