Abstract
Steering a vehicle may include applying a net brake-steering force to a steered wheel sufficient to affect a steering moment upon the steered wheel sufficient to move the steered wheel away from a zero steering angle, and resisting movement of the steered wheel back toward the zero steering angle.
Claims1
A system comprising:
- a steered wheel;
- a steering angle sensor to detect a steering angle of the steered wheel;
- a braking system for braking the steered wheel;
- a damping system for damping steering movement of the steered wheel;
- and a control system, comprising a processor and memory, operably coupled to the braking system and damping system to periodically brake the steered wheel comprising pulsed brake pressure control of a brake at the steered wheel sufficient to affect a steering moment upon the steered wheel sufficient to incrementally move the steered wheel toward a desired steering angle and to prevent reverse motion of the steered wheel when a desired steering angle is attained, wherein the pulsed brake pressure control comprises an oscillating brake pressure having a maximum of the pulse pressure being less than 40 bar and a minimum pulse pressure of greater than 25 bar.
