PROBLEM TO BE SOLVED: To provide an electric-vehicular brake force control apparatus capable of reducing generation of yaw moment unintended by a driver of an electric vehicle that drives drive wheels with motors, where an occurrence of shorting failure on one of left and right motors causes generation of brake force in a drive wheel on the failed side due to a recycling current.SOLUTION: In a case where a shorting failure is detected in one of left and right motors 3L, 3R, a brake force control part 9 gives brake force to a wheel on the other side of the left and right wheels in which the shorting failure is detected in the motor. This suppresses a difference in braking force between the left and right wheels, reducing generation of yaw moment unintended by a driver.SELECTED DRAWING: Figure 1

    【課題】電動モータにより駆動輪を駆動する電動車両では、左右の電動モータの一方に短絡故障が発生すると、循環電流によって故障側の駆動輪に制動力が発生する。ドライバの意図しないヨーモーメントの発生を低減できる電動車両の制動力制御装置を提供する。【解決手段】制動力制御部9は、左右電動モータ3L,3Rの一方に短絡故障が検出された場合、短絡故障が検出された電動モータと左右反対側の車輪に制動力を付与する。これにより、左右の制動力差を抑制し、ドライバの意図しないヨーモーメントの発生を低減する。【選択図】図1
