The invention provides a vehicle drive control apparatus and a control method of the vehicle drive control apparatus. The present invention is provided with: a first release processing unit (314) that, when a rotation speed (RS) is equal to or less than a speed threshold (RTH) during a three-phase short-circuit control by a motor driver (14), releases the rotation speed (RS) when the value of a current flowing through one of three motor coils (15U, 15V, 15W) of a three-phase motor (15) is equal to or less than a first threshold (TH1), which is greater than zero, and is equal to or greater than zero, if the value of a current flowing through one coil of the three motor coils (15U, 15V, 15W) is equal to or less than a first threshold (TH1), which is greater than zero, and is equal to or greater than zero; turning off the MOSFET on the negative side corresponding to the one coil; and a second release processing unit (315) that turns off the negative-side MOSFETs respectively corresponding to two coils among the three motor coils (15U, 15V, 15W) when the value of the current flowing through the two coils other than the one coil is equal to or less than a second threshold value (TH2).
提供车辆驱动控制装置和车辆驱动控制装置的控制方法。具备:第一解除处理部(314),其在马达驱动器(14)执行三相短路控制的过程中,在转速(RS)为速度阈值(RTH)以下的情况下三相马达(15)的三个马达线圈(15U、15V、15W)中流过的电流的值(IU、IV、IW)中的、一个线圈中流过的电流的值为大于零的第一阈值(TH1)以下且为零以上时,使与所述一个线圈对应的负侧的MOSFET断开;以及第二解除处理部(315),其在三个马达线圈(15U、15V、15W)中的除了所述一个线圈以外的两个线圈中流过的电流的值为第二阈值(TH2)以下时,使与所述两个线圈分别对应的所述负侧的MOSFET断开。
