Attorney, Agent or FirmInternational ClassG01P 015/00AbstractAn acceleration measuring system, mountable on the body of a vehicle of the type having a suspension system which permits the vehicle to pitch and roll with respect to the surface over which the vehicle travels, determines and displays the lateral and forward acceleration of the vehicle in the plane of the surface. The system includes an acceleration transducer arrangement which provides indications of acceleration in nominal lateral, forward, and vertical directions. A programmed microprocessor transforms these indications of acceleration to a coordinate system in which two axes are parallel to the surface. A display provides a visual display of acceleration in the two axes.Other References
