【摘要】:To provide a vehicle behavior stabilization device instantly lowering a drive wheel slip ratio to secure stability of the vehicle behavior even when entering a low-friction-coefficient road surface during speed-reduction control when running on a high-friction-coefficient road surface, or when the drive wheel slip ratio is drastically increased by fail control. ! This vehicle behavior stabilization device is provided with: a vehicle behavior unstability detection means; a motor control means controlling the output of a motor in response to the state of the motor; a motor output transmission control means controlling the transmission of the output of the motor of the motor control means to a wheel; and a drive wheel lock tendency detection means detecting the lock tendency of the drive wheel of the vehicle. The motor output transmission control means controls a transmission ratio based on the output of the drive wheel lock tendency detection means when the output of the drive wheel lock tendency detection means is in a first predetermined range during speed reduction control execution, and stops the transmission of the output of the motor to the wheel when the output of the drive wheel lock tendency detection means is in a second predetermined range representing stronger lock tendency than that of the first predetermined range. !
