Abstract: Apparatus (1) for determining the ride height dimension H of a vehicle between a first reference point (A) fixed relative to the vehicle and a second reference point (B) fixed relative to the ground comprises apparatus (1) for determining spherical co-ordinates A (ra, thetaa, phia) and B(rb, thetab, phib) which define the locations of the first and second reference points A and B, respectively, in three-dimensional space relative to a datum point 10. The apparatus determines Cartesian co-ordinates A(xa, ya, za) and B(xb, yb, zb) from the corresponding spherical co-ordinates, and where the ride height dimension is a vertical dimension between the first and second reference points A and B, the ride height dimension is computed by subtracting the vertical Cartesian co-ordinate za of the first reference point A, thus producing the ride height dimension from the formula : ride height H = za - zb H = racosphia - rbcosphib.

Abstract: Apparatus (1) for determining the ride height dimension H of a vehicle between a first reference point (A) fixed relative to the vehicle and a second reference point (B) fixed relative to the ground comprises apparatus (1) for determining spherical co-ordinates A (r a , θ a , φ a ) and B(r b , θ b , φ b ) which define the locations of the first and second reference points A and B, respectively, in three-dimensional space relative to a datum point 10. The apparatus determines Cartesian co-ordinates A(x a , y a , z a ) and B(x b , y b , z b ) from the corresponding spherical co-ordinates, and where the ride height dimension is a vertical dimension between the first and second reference points A and B, the ride height dimension is computed by subtracting the vertical Cartesian co-ordinate z a of the first reference point A, thus producing the ride height dimension from the formula : ride height H = z a - z b H = r a cosφ a - r b cosφ b .
