Abstract
Each of target braking forces for front and rear wheels of a vehicle is calculated based on an amount of braking performed by a driver and a predetermined braking force distribution ratio between the front wheels and the rear wheels. Each of the target regenerative braking forces for the front and rear wheels, respectively, is calculated based on a corresponding one of the target braking forces such that a maximum regeneration efficiency is obtained. If the driver has performed an abrupt braking operation, if the driver has performed a braking operation when the vehicle runs at a high deceleration, or if the vehicle runs at a high lateral speed, it is quite likely that anti-skid control will be started afterwards. Therefore, the target regenerative braking forces are gradually reduced, and target frictional braking forces are gradually increased. If anti-skid control is started, the target regenerative braking forces are set as 0.
