Abstract:
1. A method of distributing braking force between front wheels and rear wheels by controlling braking force on a rear right wheel and a rear left wheel such that an actual wheel speed of each rear wheel follows a target wheel speed thereof, the method comprising the steps of: calculating a current target wheel speed of each rear wheel to be used based on an actual deceleration speed of the right front wheel, the left front wheel or both from wheels and a previous target wheel speed of each rear wheel; and controlling braking force on each of the rear wheels based on the thus calculated current target wheel speed, wherein, the current target wheel speed of each rear wheel to be used is calculated by: setting an actual deceleration speed of the right front wheel, the left front wheel or both front wheels as a target deceleration speed of each rear wheel; and calculating a value obtained by subtracting the target deceleration speed of each rear wheel from a corresponding previous target wheel speed of each rear wheel; and wherein, if at least one of the actual deceleration speeds of the front wheels is larger than a predetermined threshold value, a predetermined deceleration speed is set as the target deceleration speed of each rear wheel.
