Patent ID: 8272699

Claim:
A brake apparatus, comprising: a wheel angular velocity detection section that detects an angular velocity of a wheel; a load estimation section that estimates a load of a wheel; a target value calculation section that calculates a target value for a braking force of at least one member of the group consisting of front wheels and rear wheels; a front/rear braking force correction value calculation section that estimates a front/rear braking force ratio that is a ratio between a front wheel braking force and a rear wheel braking force based on the angular velocity and the load at a time of braking, and calculates a front/rear braking force correction value for controlling a braking force of at least one member of the group consisting of front wheels and rear wheels based on the front/rear braking force ratio; a command value calculation section that calculates a braking force command value based on the braking force target value and the front/rear braking force correction value; and a braking force generation section that generates a braking force at a wheel based on the braking force command value, wherein the front/rear braking force correction value calculation section estimates a total braking force of all wheels based on the front/rear braking force ratio and a deceleration of the vehicle, and calculates the front/rear braking force correction value based on the front/rear braking force ratio and the total braking force.
