Abstract

Apparatus (10) for testing the cornering stability of a vehicle (12) to determine when the vehicle begins to slide or tip over when rounding a corner. A movable platform (32) is capable of supporting the weight of a vehicle, and the vehicle is positioned on one end of the platform. A counterweight (42) is positioned at the opposite end of the platform. The platform is rotatable through a range of speeds to simulate vehicle movement in a circular path such as when the vehicle is rounding a corner. Sensors are attached to wheels (T3, T4) of the vehicle to detect a sliding movement of the vehicle relative to the platform. A lifting movement which occurs when the vehicle begins to tip over, is also detectable. A method of determining a vehicle's center of gravity which will provide stability is also disclosed.
