ABSTRACT:
A braking control apparatus for an electric motor operated vehicle including contactors for controlling the direction of rotation of a DC electric motor to effect change-over between the forward and backward modes of running of the vehicle, and a chopper circuit whose duty cycle is varied in response to the accelerator position is disclosed to comprise forward/backward change-over detecting means for detecting a change-over from the forward mode of running to the backward mode of running or vice versa, and regenerative braking activating means for effecting regenerative braking whe the forward/backward change-over detecting means detects the occurrence of change-over from the forward to the backward mode of running or vice versa.
