A regenerative braking control apparatus for a wheeled vehicle, includes: a regenerative braking unit arranged to produce a regenerative braking effort for the vehicle; and a control unit connected for signal communication to the regenerative braking unit, and configured to perform the following: measuring a wheel speed deviation defined as a difference between a speed of a front wheel set of the vehicle and a speed of a rear wheel set of the vehicle; and controlling the regenerative braking effort in accordance with the wheel speed deviation during cornering. The control unit is configured to control the regenerative braking effort to decrease with an increase in the wheel speed deviation during cornering braking, and configured to perform braking for the vehicle in accordance with an operation of slowdown request, prioritizing a regenerative braking effort for one of the front wheel set and the rear wheel set of the vehicle.read more
