Abstract
An operating device for steering a vehicle, in particular a motor vehicle, and a method for steering the vehicle by way of the operating device. The operating device comprises a control stick, in particular for operation by a human hand. The control stick has at least one degree of freedom. A steering angle can be specified by way of the control stick. The operating device comprises a control element. The specifiable steering angle can be determined as a function of a state of the control stick and as a function of a state of the control element.
Claims13
An operating device for steering a vehicle, the operating device comprising a control stick and a control element;
- and
- wherein the control stick and the control element are concurrently operable to control vehicle steering during a steering maneuver;
- wherein a state of the control stick relative to at least one degree of freedom determines a first signal which contributes a first control contribution of a steering angle (α) of the vehicle;
- wherein a position of the control element is adjustable during operation of the control element determines a second signal that contributes a second control contribution of the steering angle (α) of the vehicle;
- wherein a third signal, corresponding to said steering angle (α) of the vehicle, is determined as a function of the first signal and the second signal with said third signal varying during said steering maneuver due to a change of said state of the control stick and said position of the control element, said second control contribution dynamically adjusting said steering angle as a correction of said first control contribution during said steering maneuver.
A method for steering a vehicle by way of an operating device comprising a control stick and control element, the control stick configured for operation by a human hand and having at least one degree of freedom, the method comprising:
- determining a first signal, which contributes a first control contribution of a steering angle (α) of the vehicle, based on a state of the control stick relative to said at least one degree of freedom;
- determining a second signal, which contributes a second control contribution of the steering angle (α) of the vehicle, based on a position of the control element;
- concurrently operating said control stick and said control element during a steering maneuver with said control stick being operated so that said second control contribution is an adjustment to said first control contribution to correct the steering angle of the vehicle;
- during said concurrently operating, responding to a change of said state of the control stick relative to said at least one degree of freedom during said steering maneuver to produce a change in said first signal;
- during said concurrently operating, responding to a change of said position of the control element during said steering maneuver to produce a change in said second signal;
- and
- determining a third signal as a function of the first signal and the second signal, wherein the third signal varies during said steering maneuver due to said change of said state of the control stick and said change of position of the control element.
