Control system for steering a tractor vehicle with a trailer
First Claim
1. A control system for steering a tractor vehicle with a trailer, comprising:
- at least one electronic control unit which has interfaces to;
a first sensor device for sensing the current bend angle of the tractor-trailer combination,a second sensor device for sensing a required driving space of the tractor-trailer combination, anda third sensor device for sensing the driving space which is present,wherein the control unit further comprises;
a collision prediction unit for comparing the required driving space with the driving space which is present while taking into account the current bend angle, anda collision prevention unit which determines, through interaction with the collision prediction unit, a bend angle which is the maximum permissible one for preventing a collision, and which collision prevention unit indicates a setting of a bend angle which exceeds the maximum permissible bend angle as critical in terms of a collision and prevents said setting or permits it only after a predefined delay.

Abstract
A control system that steers a tractor vehicle with a trailer has at least one electronic control unit which has interfaces to a first sensor device for sensing the current bend angle, a second sensor device for sensing the required driving space of the tractor-trailer combination, and a third sensor device for sensing the driving space which is present. The control unit also has a collision prediction unit for comparing the required driving space with the driving space which is present while taking into account the current bend angle, and a collision prevention unit which determines, through interaction with the collision prediction unit, a bend angle which is the maximum permissible one for preventing a collision. The collision prevention unit indicates a setting of a bend angle which exceeds the maximum permissible bend angle as critical in terms of a collision and prevents the setting or permits it only after a predefined delay.

6. A method of steering a tractor vehicle with a trailer forming a tractor-trailer combination, the method comprising the acts of:
-
sensing, using a first sensor, a current bend angle of the tractor-trailer combination; sensing, using a second sensor, a required driving space of the tractor-trailer combination; sensing, using a third sensor, a driving space that is presently available; comparing, using a collision prediction unit, the required driving space with the driving space presently available while factoring into account the current bend angle; determining, using a collision prevention unit, a bend angle which is a maximum permissible bend angle to prevent a collision; and indicating, using the collision prevention unit, a setting of the bend angle which exceeds the maximum permissible bend angle as critical and preventing said setting of the bend angle which exceeds the maximum permissible bend angle or permitting said setting only after a predefined delay. - View Dependent Claims (7, 8, 9, 10)
