Abstract

A system for guiding a vehicle includes first and second operating elements, which are configured to influence a wheel steering angle of the vehicle and are not mechanically coupled to one another. A target steering angle is determined as a function of a sum of steering torques, which is dependent on a target steering torque and actual steering torques of the first and of the second operating elements. The first and second actual steering angles are adjusted as a function of the target steering angles in the respective first and second operating elements. A target wheel steering angle is determined as a function of the target steering angle, wherein the sum of steering angles includes two summands dependent on the first actual steering angle and the second actual steering angle, respectively. The wheel steering angle is adjusted as a function of the target wheel steering angle.

Dependent claims

A method for guiding a vehicle having a system that includes a first operating element and a second operating element for influencing a wheel steering angle of the vehicle, wherein the first operating element and the second operating element are not mechanically coupled to one another, the method comprising:

determining a target steering angle as a function of a sum of steering torques, the sum of steering torques including a first summand dependent on a target steering torque, a second summand dependent on an actual steering torque of the first operating element, and a third summand dependent on an actual steering torque of the second operating element,
adjusting a first actual steering angle of the first operating element as a function of the target steering angle;
adjusting a second actual steering angle of the second operating element as a function of the target steering angle;
determining a target wheel steering angle as a function of the target steering angle or as a function of a weighted sum of steering angles, the weighted sum of steering angles including a fourth summand dependent on the first actual steering angle and a fifth summand dependent on the second actual steering angle;
and
adjusting the wheel steering angle as a function of the target wheel steering angle.
