The invention provides a vehicle drive control device and a control method thereof, which can suppress overcurrent of a switching element of a motor driver. A vehicle drive control device (100) is provided with a motor driver (14), a contactor (12), a capacitor (13), and a control device (3), and the control device (3) is provided with: a voltage acquisition unit (311) that acquires a capacitor voltage (VC); a current acquisition unit (312) that acquires a current value (IU), a current value (IV), and a current value (IW) of a current flowing through each coil of the motor (15); and a voltage control unit (314) and a voltage control circuit (33) that, when the contactor (12) is turned off, calculate a control angle ([theta] S), which is a rotation angle ([theta]) for controlling the motor (15), and control the motor driver (14) on the basis of the current value (IU), the current value (IV), the current value (IW), and the control angle ([theta] S).
