Abstract

When braking of the electric vehicle is performed, the braking is controlled based on a target braking split ratio which is a target value of the ratio of the braking force that is applied to the rear wheels to a total braking force that is applied to the front and rear wheels. In this case, an initial value of the target braking split ratio is set to a value within an allowable range about a transmission split ratio when braking of the electric vehicle is started while the electric vehicle is being braked by the motor, the transmission split ratio being the ratio of a braking force that is transmitted from a drive shaft to the rear wheels via a driving force split device to a total braking force that is transmitted from the drive shaft to the front and rear wheels via the driving force split device.
