Abstract

The present invention is entitled "Method for Impedance Control of a Steering System". The present invention provides an exemplary method for controlling a vehicle comprising providing a vehicle steering system comprising a movable steering column assembly and a movable steering wheel assembly, a first actuator and a second actuator, The first actuator and the second actuator are configured to move the vehicle steering system from a first position to a second position; providing a plurality of sensors configured to measure force characteristics; providing electrical connections to the sensors and the vehicle a controller of the steering system; monitor first sensor data received from the first sensor and second sensor data received from the second sensor; generate a reference model based on the expected output displacement and the first sensor data and the second sensor data; based on the reference The model calculates the corrected output displacement; and automatically generates a first control signal to control the first actuator and a second control signal to control the second actuator.

Description

technical field [0001] The present invention relates generally to the field of vehicles, and more particularly to steering wheels and steering columns for motor vehicles. Background technique [0002] Autonomous and semi-autonomous vehicles may include telescoping steering columns to allow the steering wheel to retract from the occupant, or foldable steering wheels and possibly other retraction mechanisms to provide more room in the cabin. During a retracting, folding or stowing operation in which the steering wheel column is moved in the axial direction, disturbances to the retracting, folding or stowing operation, such as a clamping event, may occur. A method of providing impedance control to the steering system and preventing pinch events can prevent bodily injury to the occupant and functional interruption of the retraction mechanism. Contents of the invention [0003] Embodiments according to the present disclosure provide a number of advantages. For example, embodi...
