Vehicle-dynamics control method and system for a vehicle train
First Claim
1. A vehicle-dynamics control method for a vehicle train, the vehicle train including a tractor vehicle and a trailer vehicle, the tractor vehicle having a vehicle-dynamics control system arranged and constructed to deliver a brake-demand value to the trailer vehicle based on vehicle dynamics signals measured in the tractor vehicle, the trailer vehicle having a brake system responsive to the brake-demand value from the vehicle-dynamics control system of the tractor vehicle, the method comprising the steps of receiving in said vehicle-dynamics control system data signals from said trailer vehicle associated with vehicle dynamics and calculating said brake-demand value based on said data signals.

Abstract
A vehicle-dynamics control method and system for a vehicle train comprising a tractor vehicle and a trailer vehicle. The vehicle-dynamics control system provided in the tractor vehicle, on the basis of vehicle-dynamics signals measured in the tractor vehicle, delivers brake-demand values (BAW) to the trailer vehicle. The trailer vehicle is equipped with a brake system, in which the brakes of the trailer vehicle can be actuated on the basis of the BAW. The vehicle-dynamics control method and system use data signals received from the trailer vehicle and calculates the BAW and permits activation of the brake system of the trailer vehicle while at the same time avoiding an undesirably large reduction of the cornering forces on the wheels of the trailer vehicle.
