Abstract
With a view to controlling the distribution of brake force onto the front and rear axles of an automotive vehicle in response to the momentarily prevailing static and dynamic axle load distribution, the wheel rotational behaviour (???) on the front axle (VA) and on the rear axle (HA) and the translational deceleration (-b) of the vehicle or variables proportional to said measured values are determined by way of sensors (8, 9, 10). After the said signals having been electronically processed and combined at (7), the share of the brake pressure (PHA) fed to the rear axle in response to the front wheel brake pressure (PVA) is so controlled by means of solenoid valves (4, 5) that the brake slip at the rear axle (HA) corresponds to the brake slip at the front axle (VA) or is slightly less than the front wheel brake pressure. In the event that nonetheless a locking tendency of the rear wheels occurs, e.g. as a result of rapidly changing road conditions, the brake pressure at the rear axle is reduced with the aid of another quick-acting electromagnetically operated valve (6) and is maintained constant at the low value until the front wheel pressure has decreased. If either circuit (2, 3) fails, sensor 18 actuates control 7 to permanently open valves 4, 5 and close valve 6. The circuits need not be diagonally split (Fig. 3 not shown). <IMAGE>
