Abstract
A vehicle braking system includes an electric motor, an operating amount detector, a brake assist controller, a first braking device and a second braking device. The electric motor drives a driving wheel via a reduction ratio setting device. The first braking device makes the electric motor generate a first braking power under regenerative control. The second braking device generates a second braking power by actuating an actuator with an operating fluid to be pressurized through a hydraulic pressure source. When an initiation condition for a brake assist control is met, the reduction ratio setting device sets a reduction ratio so as to reduce the first braking power and then suspends a change in the reduction ratio, and the first braking device generates the first braking power as well as the second braking device generates the second braking power to produce a target braking power.
