A method and apparatus for providing a measurement of wheel forces (Fx, Fy, Fz) on a vehicle wheel assembly (10) to enhance safety by providing electronic braking and power train controls with information about vehicle loading and road surface conditions. The apparatus includes a pair of beams (A, B) coupling an inner knuckle (22) to an outer knuckle (20) upon which the vehicle wheel assembly (10) is mounted. Strain sensors (S<SUB>A</SUB>, S<SUB>B</SUB>) mounted to the beams (A, B) provide measures of longitudinal bending of beams (A, B). A ball joint (26) for attachment of additional suspension components is coupled to the outer knuckle (20) by a beam (C), and a load sensor (SC) disposed on beam C measures the horizontal lateral forces exerted thereon. Signal from the sensors (S<SUB>A</SUB>, S<SUB>B</SUB>, S<SUB>C</SUB>) are processed to identify component forces (Fx, Fy, Fz) acting on the wheel assembly (10). |
