To provide a drive control device capable of suppressing destabilization of behavior of a car due to an output torque difference on left and right drive wheels, and preventing an excessive load applied to a power device.SOLUTION: A drive control device is applied for a car comprising a plurality of motors 6 which can independently drive left and right wheels. A motor drive controller 22 comprises: a maximum torque calculation part 35 for calculating a maximum torque value which can be output using rotation speed of the motor 6; and a torque restriction part 36 for restricting torque of the motor 6 using the calculated maximum torque value. The maximum torque calculation part 35 calculates a maximum torque value which can be output from, on the basis of rotation speed of each motor 6, out of the left and right motors, when a car speed is equal to or less than a predetermined value. When the car speed is greater than the predetermined speed, the maximum torque calculation part calculates a maximum torque value common to both of left and right wheels, using a higher rotation speed, out of rotation speeds calculated by the left and right motors 6.SELECTED DRAWING: Figure 3

    【課題】左右の駆動輪の出力トルク差により車両の挙動が不安定化することを抑制することができ、かつパワーデバイスに過大な負荷を与えることが防止できる駆動制御装置を提供する。【解決手段】この駆動制御装置は、左右独立駆動可能な複数のモータ6を搭載した車両に適用される。モータ駆動制御装置22は、モータ6の回転速度を用いて出力可能な最大トルク値を算出する最大トルク算出部35と、計算された最大トルク値を用いてモータ6のトルクを制限するトルク制限部36とを備える。最大トルク算出部35は、車速が定められた値以下である場合は左右のモータ6のそれぞれの回転速度よりそれぞれの出力可能な最大トルク値を算出する。車速が定められた値よりも高い場合は左右のモータ6につきそれぞれで算出した回転速度のうち高い方の回転速度を用いて左右両輪共通の最大トルク値を算出する。【選択図】図3
