Tire slip model
First Claim
1. A vehicle brake system comprising:
- a brake actuator associated with a tire, said brake actuator having at least one moveable brake component;
a brake control system operative to determine a target position of the at least one moveable brake component based at least in part upon a relationship between an actual tire/road friction force and a target tire/road friction force; and
wherein said brake control system is operable to control actuation of said brake actuator based at least in part upon the target position of the at least one moveable brake component and at least in part based upon a current position of the at least one moveable brake component.

Abstract
A vehicle brake system includes a brake actuator associated with a tire, the brake actuator having at least one moveable brake component, and a brake control system. The brake control system is operative to determine a target position of the at least one moveable brake component based at least in part upon a relationship between an actual tire/road friction force and a target tire/road friction force, and to control actuation of the brake actuator based at least in part upon the target position of the at least one moveable brake component and at least in part based upon a current position of the at least one moveable brake component. The target tire/road friction force may be determined based at least in part upon a relationship between vertical force acting on the tire, optimal tire slip, slip angle, at least one road dependant parameter, and at least one tire dependant parameter.

14. A vehicle brake system comprising:
-
a brake actuator associated with a tire, said brake actuator having at least one moveable brake component; a brake control system operative to determine a target rotational velocity of the wheel based at least in part on a relationship between an actual tire/road friction force and a target tire/road friction force, said brake control system determining a target position of the at least one moveable brake component based at least in part upon the target rotational velocity; wherein the target tire/road friction force is determined based at least in part upon a relationship between vertical force acting on the tire, optimal tire slip, slip angle, at least one road dependant parameter, and at least one tire dependant parameter; and wherein said brake control system is operable to control actuation of said brake actuator based at least in part upon the target position of the at least one moveable brake component and at least in part based upon a current position of the at least one moveable brake component. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
