Abstract
A braking control device, includes a regenerative braking control part, a wheel speed differential detection part, and a regenerative restriction part. The regenerative braking control part is configured to carrying out regenerative braking on the drive wheels based on a deceleration request operation. The wheel speed differential detection part is configured to determine a wheel speed differential between the driven wheel speed and the regenerative braking wheel speed. The regenerative restriction part is configured to restrict the regenerative braking amount when the wheel speed differential exceeds a restriction initiation threshold value. The regenerative restriction part, during restriction of the regenerative braking amount, is configured to repeatedly carrying out a restriction in accordance with a large restriction phase in which a decrease in gradient of the regenerative braking amount is large and a restriction in accordance with a small restriction phase in which the decrease in gradient is small.
