  • System for control of brake actuator based at least in part upon tire/road friction force
    Patent number: 7448701
    Abstract: A vehicle brake system includes a brake actuator associated with a wheel, the brake actuator having at least one moveable brake component, and 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, the 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. The brake control system is operable 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.

  • System for control of brake actuator
    Patent number: 7347304
    Abstract: A vehicle brake system includes a brake actuator, a brake controller operative to control the brake actuator, and at least one position sensor which senses a current position of at least one moveable brake component and provides a current position signal indicative of the current position of the at least one moveable brake component to the brake controller. The brake controller is operative to cause actuation of the brake actuator based at least in part upon a position indicative command received by the brake controller indicative of a commanded position of the at least one moveable brake component and at least in part based upon the current position signal.

  • Tire slip model
    Patent number: 7314257
    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.
