Abstract
A method of operating a brake system comprises determining a predicted braking effectiveness for a plurality of vehicle braking operations and determining an actual braking effectiveness for the plurality of vehicle braking operations. The predicted braking effectiveness is compared to the actual braking effectiveness. An adjustment factor for the brake system is determined based upon the comparison and the brake system response is adjusted based on the determined adjustment factor.
Claims14
A method of operating a brake system comprising:
- determining a predicted braking effectiveness by comparing an original braking pressure and a predicted vehicle deceleration for a plurality of vehicle braking operations, wherein the predicted braking effectiveness is based upon an initial predicted braking effectiveness value in the electronic control unit, and wherein the initial predicated brake effectiveness is applied at an initial brake operation following assembly of the vehicle;
- determining an actual braking effectiveness by comparing the original braking pressure and an actual vehicle deceleration for the plurality of vehicle braking operations;
- comparing the predicted braking effectiveness to the actual braking effectiveness;
- determining an adjustment factor for the brake system based upon the comparison, wherein the adjustment factor is dependent on the original braking pressure, and wherein the adjustment factor is initially based upon a predicted decreased brake effectiveness due to a coating applied to at least one of the brakes;
- and
- adjusting the brake system response based on the determined adjustment factor.

A method of operating a brake system comprising:
- determining a predicted braking effectiveness for a plurality of vehicle braking operations where active braking interventions are not applied, wherein the predicted braking effectiveness is based upon an initial predicted braking effectiveness value in the electronic control unit, wherein the initial predicated brake effectiveness is applied at an initial brake operation following assembly of the vehicle;
- determining an actual braking effectiveness for the plurality of vehicle braking operations;
- comparing the predicted braking effectiveness to the actual braking effectiveness;
- determining an adjustment factor for the brake system based upon the comparison, wherein the adjustment factor is dependent on the original braking pressure, and wherein the adjustment factor is initially based upon a predicted decreased brake effectiveness due to a coating applied to at least one of the brakes;
