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.hact becomes substantially equal to F.sub.hdes resulting in braking of the vehicle train with optimal stability.
