Driving device with rotating electric machine

In a vehicle having a motor as the drive power source, a fuel cell and battery are on board as the power source for the motor. A target output value for the fuel cell is set within a range such that fuel cell output can track change in power demand. The battery is charged/discharged so as to compensate for delay in fuel cell output relative to power demand. By setting a higher target output value the lower the remaining charge in the battery, the fuel cell can be utilized efficiently while ensuring good output responsiveness.

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.

Brake controlling apparatus for electric vehicle

A drive system for an electric vehicle, which can make the number of parts as small as possible and minimize the space for arranging the parts in a direction perpendicular to the axis.
