Abstract
A hydraulic dual-circuit braking system comprising two main cylinders combined in twin-type construction which is actuated via a torque-equalized rocker operated by an actuating force proportional to brake pedal force, and wherein the main cylinders have position transmitters to detect piston positions, which are indirectly a measure of the brake pressure, and wherein an anti-blocking system enables the front wheel brakes to be blocked off from their main cylinders. The position signals are used by an electronic processing unit to determine the instantaneous front axle/rear axle braking force distribution, and compares this with a value which is ideal in accordance with the vehicle data, and when this comparison shows that the rear axle braking force component is too low, the front-wheel brakes are blocked off from their main cylinders until the rear axle braking force component is increased to such an extent that the ideal braking force distribution has been almost achieved. The front wheel blocking is then halted and both braking forces increase until the next under comparison situation is reached. The cycle of operation is then repeated.
