ABSTRACT:
A vehicle behavior detection apparatus can accurately detect an unstable state of a vehicle without making an incorrect determination even if a travel environment of the vehicle is abnormal. The apparatus includes a road surface reaction torque detecting unit that detects a road surface reaction torque which a tire of the vehicle receives from a road surface, a steering angle detecting unit that detects a steering angle of the vehicle, a vehicle speed detecting unit that detects a speed of the vehicle, a standard road surface reaction torque calculating unit that calculates a standard road surface reaction torque from the steering angle and the vehicle speed, a vehicle behavior state detecting unit that detects the unstable state of the vehicle, and a vehicle behavior detection inhibiting unit that invalidates the vehicle behavior state detecting unit based on the road surface reaction torque and the standard road surface reaction torque.
