Abstract
A braking system for a vehicle includes a processing circuit, a pad position detector, a pressure sensor, a pad positioner and a pressure combiner. The pressure sensor and the pad positioner are adapted to determine a thickness of a friction material of a pad of the braking system. The pad position detector is adapted to detect the position between the pad and a rotor of the braking system. The pad positioner and the pressure combiner are adapted to determine a desired position between the pad and the rotor to provide a desired braking response time and a desired amount of drag.
Claims20
A braking system for a vehicle, the braking system comprising
- a rotor;
- a pad, a resilient force positioned the pad a first distance away from a face of the rotor;
- a master cylinder adapted to report a first pressure, the first pressure proportional to a force applied to a brake pedal;
- a pad positioner adapted to report a second pressure, the second pressure adapted to overcome the resilient force to position the pad a second distance away from the face of the rotor, the second distance less than or equal to the first distance;
- a pressure combiner adapted combine the first pressure and the second pressure to provide a brake fluid at a third pressure;
- wherein:
- while the force is not applied to the brake pedal, the third pressure positions the pad the second distance away from the face of the rotor;
- and
- while the force is applied to the brake pedal, the third pressure positions the pad against the face of the rotor to slow a rotation of the rotor.
