METHOD AND ARRANGEMENT FOR VEHICLE STABILIZATION
First Claim
1. An arrangement for improving stability of a vehicle combination comprising a towing vehicle and at least one towed vehicle, where the at least one towed vehicle comprises at least one actively steered axle and/or an individually controlled wheel brake on at least one axle, where the towing vehicle and the at least one towed vehicle each comprises a lateral acceleration determining means for determining the lateral acceleration of the towing vehicle and the at least one towed vehicle, where the arrangement further comprises a vehicle combination model adapted for determining a desired delay value between the lateral acceleration of the towing vehicle and the lateral acceleration of the at least one towed vehicle, the arrangement is adapted to stabilise the at least one towed vehicle by using the determined lateral acceleration of the towing vehicle and the desired delay value for the at least one towed vehicle to establish a reference lateral acceleration for the at least one towed vehicle, and to control the steered axle and/or the individually controlled brake of the at least one towed vehicle such that the determined lateral acceleration of the at least one towed vehicle corresponds to the reference lateral acceleration of the at least one towed vehicle.

Abstract
An arrangement for improving stability of a vehicle combination including a towing vehicle and at least one towed vehicle, where the at least one towed vehicle includes at least one actively steered axle and/or individual brake on at least one axle. The towing vehicle and the at least one towed vehicle each includes a lateral acceleration determining means. The arrangement further includes a vehicle combination model adapted for determining a desired delay value between the lateral acceleration of the towing vehicle and the lateral acceleration of the at least one towed vehicle. The arrangement is adapted to stabilize the at least one towed vehicle by using the determined lateral acceleration of the towing vehicle and the desired delay value for the at least one towed vehicle to establish a desired lateral acceleration for the at least one towed vehicle, and to control the steered axle and/or the individual brake of the at least one towed vehicle such that the determined lateral acceleration of the at least one towed vehicle corresponds to the desired lateral acceleration of the at least one towed vehicle.

17. A method for stabilizing a vehicle combination comprising a towing vehicle and at least one towed vehicle, comprising the following steps:
-
establish a desired delay value for the lateral acceleration between the towing vehicle and the at least one towed vehicle in the vehicle combination by using a vehicle combination model, determine the lateral acceleration of the towing vehicle, establish a reference lateral acceleration value for each towed vehicle by using the determined lateral acceleration of the towing vehicle and the established delay value, determining the actual lateral acceleration of the at least one towed vehicle, comparing the actual lateral acceleration with the reference lateral acceleration, controlling the lateral acceleration of the at least one towed vehicle to the reference lateral acceleration value by controlling steering axles and/or individual brakes on the at least one towed vehicle. - View Dependent Claims (18, 19, 20)
