Abstract: A process for braking a vehicle having at least first and second brakes, comprises supplying energy to the first and second brakes so as to actuate them, the energy being distributed between the first and second brakes in accordance with the brakes' response energies. Preferably, the momentary values of the response energies are used so that the first and second brakes are actuated simultaneously.

Abstract: A method and system for operating an electrically controlled pressurized-fluid vehicle brake system having a brake cylinder for actuating a brake, a braking-pressure sensor for obtaining braking-pressure data which indicate the braking pressure in the brake cylinder, a valve device for influencing the braking pressure by which the brake cylinder can communicate optionally with a supply pressure or with a set pressure in order to feed pressurized fluid, and a set-pressure sensor for obtaining set-pressure data. Braking pressure is adjusted as dictated by the set-pressure data and/or by the braking-pressure data. The set-pressure data are checked by temporarily switching the pressurized-fluid feed path to the brake cylinder from the supply pressure to the set pressure by actuation of at least one part of the valve device, and then monitoring the resulting braking pressure based on the braking-pressure data.

Abstract: A process to determine the response pressure of a brake in a braking system of a vehicle comprises: measuring the existing vehicle deceleration of the vehicle to determine a value of ground-vehicle deceleration, supplying a test pressure to the brake, measuring the deceleration of the vehicle after the test pressure has been supplied to the brake to determine a value of vehicle test deceleration, and comparing the value of ground-vehicle deceleration and the value of vehicle test deceleration. If the value of vehicle test deceleration is greater than the value of ground-vehicle deceleration by more than a predetermined tolerance value, the steps of the process are repeated with a reduced test pressure until the difference between the values of ground-vehicle deceleration and vehicle test deceleration is no more than the predetermined tolerance value.

Abstract: A process and apparatus for the braking with optimized stability of a vehicle train is disclosed. The vehicle train comprises at least two individual vehicles, one of the individual vehicles supporting the individual vehicle. The process comprises supplying energy to the brakes of the vehicles, thereby actuating the brakes and producing an actual force between the vehicles, and measuring the actual-value horizontal and vertical components (F.sub.hact, F.sub.vact) of the actual force (F.sub.act) acting between the supporting and supported vehicle. A desired-value horizontal force component (F.sub.hdes) of the force is determined by multiplying the actual-value vertical component (F.sub.vact) by the ratio of the actual-value train deceleration (b) to the earth's acceleration (g). The desired-value horizontal force component (F.sub.hdes) is then compared with the actual-value force horizontal component (F.sub.hact). The energy supplied to the brakes is adjusted so that F.sub.
