Abstract: The growing demand for safety, comfort, and ride performance in the automotive industry motivates the design of advanced sensory systems. In this work, a sensory system is designed which measures the wheel forces and moments in every direction. The design benefits from a compact configuration by only modifying one part of the vehicle|s current wheel assembly. The forces and moments are measured using the deflections of a flexible cylindrical layer embedded in the external hub of the wheel bearing assembly, where all the loads transmit through.

Keywords: sensor design; tyre load monitoring; force; torque; load; vehicle tyres; wheels; vehicle dynamics; vehicle control; wheel forces; wheel assembly; deflection; wheel bearing assembly.
