Abstract
Disclosed is 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. 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.
Claims16
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 torque of a steering line of the vehicle dependent on a difference between the nominal steering angle and an instantaneous steering angle;
- estimating a value of a load moment acting on the steering line of the vehicle based upon a hand moment, a motor moment, a steering column steering angle and a steering angle velocity of a steering column;
- and
- applying an additional torque to the determined steering torque of the steering line of the vehicle, wherein the additional steering torque is established dependent on the estimated value for the load moment;
- wherein the additional steering torque is composed of at least two additive components, with a first component being determined dependent on the difference between the nominal steering angle and the instantaneous steering angle, and a second component is established dependent on the estimated value of the load moment.
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 the 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, wherein the load moment is vehicle based upon a hand moment, a motor moment, a steering column steering angle and a steering angle velocity of a steering column;
- 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.
