Abstract
A vehicular braking apparatus includes an electric motor that generates a wheel driving force or a regenerative wheel braking force and also includes a mechanical wheel braking force generating device, an external braking force generating device, and a braking control device. The mechanical wheel braking force generating device includes a working fluid pressure adjusting unit that generates a mechanical wheel braking force by transmitting the pressure of a working fluid. The external braking force generating device applies an external braking force other than a regenerative vehicle braking force generated by the electric motor and a mechanical vehicle braking force generated by the mechanical wheel braking force generating device, to a vehicle. The braking control device compensates a braking force by an external braking force in order to satisfy a requested vehicle braking force by a driver when the conversion efficiency of the electric motor to electrical energy is decreased.
