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 current values (IU, IV, IW) of current flowing through each coil of the motor (15); an angle acquisition unit (313) that acquires the rotation angle (theta) of the motor (15); an axis current calculation unit (314) that calculates a q-axis current value (IQ) and a d-axis current value (ID) on the basis of the current values (IU, IV, IW) and the rotation angle (theta); and a voltage control unit (315) that, when the contactor (12) is turned off, controls the q-axis current (JQ) so as to maintain the capacitor voltage (VC) at or below a predetermined voltage.
