Abstract
A braking force distribution apparatus for a vehicle includes pressure sensors for detecting the internal pressures of the tires, and wheel speed sensors for detecting the angular speeds of the wheels. The apparatus obtains a dynamic load radius change rate of each tire which corresponds to the deviation of the internal pressure of the tire from a reference pressure, obtains a wheel speed for calculation of a slip value on the basis of the angular speed of the tire and the change rate, and obtains a slip value on the basis of the obtained wheel speed. As a result, EBD control is started at proper timing in accordance with the slip value.
