To provide a vehicular drive power control apparatus capable of appropriately eliminating a play in a differential mechanism and a play in a torque transmission path between the differential mechanism and front and rear wheels when the vehicle is stopped with braking applied to each wheel.SOLUTION: A vehicular drive power control apparatus includes: a first output shaft connected to a drive power source and a rear wheel; a second output shaft connected to a front wheel; and a differential mechanism that is differentially rotatably connected to a motor and disposed so that a direction of torque output from the motor exerted to the first output shaft is opposite to a direction of the aforementioned torque exerted to the second output shaft. When a vehicle is stopped, the control apparatus causes the drive power source to output predetermined drive torque and causes the motor to output control torque where a difference between torque transmitted from the drive power source to the first output shaft and the torque exerted from the motor to the first output shaft is equal to or higher than predetermined first torque, with the torque exerted from the motor to the second output shaft equal to or higher than predetermined second torque (step S3).SELECTED DRAWING: Figure 4 【課題】各車輪にブレーキを作用させた停車時に差動機構および差動機構と前輪および後輪との間のトルクの伝達経路のガタ詰めを適切に行うことができる車両の駆動力制御装置を提供する。【解決手段】駆動力源および後輪に連結された第１出力軸と、前輪に連結された第２出力軸と、モータとが差動回転可能に連結されるとともに、モータから出力するトルクが第１出力軸に作用する向きと第２出力軸に作用する向きとが反対方向となるように構成された差動機構とを備え、車両の停車時に、駆動力源から予め定められた駆動トルクを出力するとともに、駆動力源から第１出力軸に伝達されるトルクとモータから第１出力軸に作用するトルクとの差が予め定められた第１所定トルク以上となり、かつモータから第２出力軸に作用するトルクが予め定められた第２所定トルク以上となる制御トルクをモータから出力する（ステップＳ３）。【選択図】図４
