Title:
ELECTRIC VEHICLE DRIVE CONTROL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2011/074045
Kind Code:
A1
Abstract:
Provided is an electric vehicle drive control apparatus, wherein fluctuation in the decelerating rate of the electric vehicle is made to be smaller, and the ride thereon is improved to become more comfortable, even when regeneration load is insufficient while regenerative braking is being activated. The electric vehicle drive control apparatus (1) is provided with an open/close unit (4) that opens or closes a connection with DC power; a power conversion unit (5), to which DC power is inputted to two input terminals thereof via the open/close unit, which converts DC power to AC power by a switching operation, and drives an AC rotating machine (13) connected to the output side thereof; and a voltage detection unit (15) that detects the voltage between the two terminals. The electric vehicle drive control apparatus (1) is also provided with a power control unit (14) that controls the power conversion unit such that the open/close unit is opened when the voltage detected by the voltage detection unit exceeds a prescribed opening voltage, and the regenerative braking force of the AC rotating machine is reduced with a prescribed reduction pattern having a ramp reduction period that is longer than 0.
