Patent ID: 7097262

Claim:
A braking force control apparatus for an automotive vehicle, comprising: a turning state variable detecting section that detects a turning state variable of the vehicle from a traveling state of the vehicle; a limit vehicular turning state variable estimating section that estimates a limit turning state variable of the vehicle by which the vehicle is stably enabled to travel from the turning state variable detected by the turning state variable detecting section; a target deceleration calculating section that calculates a target deceleration required when the vehicle approaches to a turning state variable set value set on the basis of the limit vehicular turning state variable estimated by the limit vehicular turning state variable estimating section; a vehicular deceleration developing section that develops the target deceleration of the vehicle calculated by the target deceleration calculating section; and a front-and-rear road wheel braking force distribution determining section that determinatively distributes a front-and-rear road wheel braking force at a front-and-rear road wheel braking force distribution toward front and rear road wheel sides of the vehicle in accordance with the limit vehicular turning state to achieve the target deceleration calculated by the target deceleration calculating section, the vehicular deceleration developing section developing the target deceleration on the basis of the front-and-rear road wheel braking force distribution determined by the front-and-rear road wheel braking force distribution determining section, wherein the front-and-rear road wheel braking force distribution determining section modifies the front-and-rear road wheel braking force distribution in accordance with a variation direction of the vehicular turning state variable and relatively enlarges the front-and-rear road wheel braking force distribution toward the front road wheel side of the vehicle on the basis of the turning state variable indicating stable transfer of the turning state in a direction where a turning radius of the vehicle becomes small as compared with a case where the turning radius of the vehicle becomes large.
