ABSTRACT:
A regenerative braking apparatus for a battery operated vehicle includes rotation direction detection devices for detecting the rotation directions of respective axles of two front wheels, a current direction judgment device for judging respective field current directions of two propulsion motors based on respective outputs from the rotation direction detection devices, and a current direction control device for controlling the field current direction of the propulsion motors based on the output from the current direction judgment device. In this way, even when close to the steering angle for inner wheel stop turning, concern for external action rotation of the propulsion motor for driving the inner wheel is eliminated, enabling control of regeneration at the time of turning to be carried out with good efficiency.
