Abstract:
A method of inspecting a cornering control mechanism of a vehicle in which a braking force is applied to wheels on an outer side of cornering when the vehicle is oversteered and a braking force is applied to wheels on an inner side of cornering when the vehicle is understeered, said inspection being performed in a state in which each of the wheels is placed on a drum of a bench type of testing apparatus, said method comprising the steps of:driving driving wheels of the vehicle by a driving source of the vehicle in a state in which each of said drums is coupled to each other through respective clutches;releasing coupling of a first drum on which one of left and right driving wheels is mounted, to a second drum when a vehicle speed has reached a predetermined speed;detecting subsequent deceleration of a first driving wheel and subsequent deceleration of a second driving wheel;discriminating whether the cornering control mechanism has operated normally or not based on the deceleration of said first driving wheel;discriminating, based on the deceleration of the second driving wheel, whether an accelerator has been switched off; andwhen a discrimination is made that the accelerator has been switched off, prohibiting the discrimination of operation of the cornering control mechanism based on the deceleration of said first driving wheel; anddiscriminating that the braking force is applied to said first driving wheel when a rate of change in the deceleration of the second driving wheel is below a first predetermined value and when the rate of change in the deceleration of said first driving wheel is above a second predetermined value.
