BRAKE CONTROLLER AND METHOD FOR CONTROLLING BRAKES
First Claim
1. A brake controller, comprising:
- a braking force application mechanism that presses a friction member against a braked member so as to apply a braking force to a wheel of a vehicle; and
a control unit that calculates an index, which indicates a difference between an estimated braking effectiveness and an actual braking effectiveness, wherein the control unit further calculates a correction amount using the index, determines whether the index is inaccurate, limits a change in the correction amount calculated using the index if it is determined that the index is inaccurate, and corrects a target value, which is set to control a pressing force of the friction member, based on the correction amount to reduce a variation in a braking effectiveness of the vehicle.

Abstract
A brake controller is provided, having a braking force application mechanism that presses a friction member against a braked member so as to apply a braking force to a wheel of a vehicle; and a control unit that calculates an index indicating the difference between an estimated braking effectiveness and an actual braking effectiveness, and calculates a correction amount using the index, determines that the index is inaccurate. The control unit further limits the change in the correction amount calculated using the index, if it is determined that the index is inaccurate, and corrects a target value, which is set to control a pressing force of the friction member, based on the correction amount to reduce a variation in a braking effectiveness of the vehicle.

14. A method of controlling a braking force applied to a wheel of a vehicle by pressing a friction member against a braked member, comprising:
-
calculating an index indicating a difference between an estimated braking effectiveness and an actual braking effectiveness; updating a correction amount based on the calculated index; determining whether an the index is inaccurate; prohibiting updating the correction amount if it is determined that the index is inaccurate; and correcting a target value, which is set for the purpose of controlling the pressing force of the friction member, by using the correction amount to reduce a variation in braking effectiveness of the vehicle.
