Abstract

A load sensor device (52) for measuring wheel contact loads applied to a suspension system (10) of the vehicle. The load sensor (52) comprises a resilient member (74) operatively connected to the suspension system (10) and to a housing (72). A circuit board (78) attaches to the suspension system (10) and the housing (72), wherein the circuit board (78) has sensors (92) attached thereon. The sensors (92) measure movements of the circuit board (78) that are created in response to the wheel loads applied through the resilient member (74).
