ABSTRACT:
A brake controlling apparatus for electric vehicles provided with a transmission between an electric motor and wheels. Regenerative brake control furnishes a regenerative braking force to the vehicle. A transmission control switches a stage of gear of the transmission the basis of driver operation. A friction brake control furnishes a friction braking force to the vehicle by controlling a friction brake. During gear shifting control, the regenerative brake control sets a regenerative torque essentially to zero, and the friction brake control supplements the regenerative braking force that was furnished to the vehicle prior to gear shifting control with the friction braking force. Therefore, there is no drop in deceleration during gear shifting control, even if the driver downshifts during regenerative braking. Smooth gear shifting is then possible.
