Abstract
A vehicle braking system of the electronically compensated type in which driver demand signals to inner closed loop pressure systems for the front and rear brakes are adjusted in accordance with load signals obtained from load sensors associated with front and rear axles of the vehicle respectively, these load signals themselves being modified to take account of the weight transfer effect from the rear axle to the front axle during braking. Weight transfer is calculated from the expression: ##EQU1## the deceleration, gross vehicle weight, height of the center of gravity of the vehicle and the vehicle wheel base being calculated and stored and manipulated electronically to provide dynamic load apportioning between the various inner closed loop pressure systems controlling the front and rear brakes, respectively.
