Patent ID: 8744712

Claim:
A drive control device for an electric vehicle that is driven by a motor-generator, comprising: a detection unit configured to detect when an accelerator pedal depression amount and a brake pedal depression amount of the electric vehicle are both zero; and a control unit configured to, when in a regeneration stopped mode that is a control mode among a plurality of modes, set a regenerative braking torque command value for the motor-generator to zero, in response to the detection unit detecting that an accelerator pedal depression amount and a brake pedal depression amount of the electric vehicle are both zero, except when a speed of the electric vehicle is less than a predetermined threshold value; and a determination unit configured to determine whether or not a maximum possible torque for regeneration of the motor-generator is greater than or equal to a predetermined regeneration stopping threshold value, wherein the maximum possible torque for regeneration of the motor-generator is calculated based upon a speed of the electric vehicle, and wherein when the determination unit determines that the maximum possible torque for regeneration of the motor-generator is greater than or equal to a predetermined regeneration stopping threshold value, the regeneration stopped mode is selected as the control mode.
