System for a Towing Vehicle
First Claim
1. A system for a vehicle having a trailer coupled thereto, the system comprising a processor configured to:
- determine an actual trailer travel direction based on one or more sensor signals;
receive a demanded trailer travel direction; and
estimate a distance to be travelled by the vehicle at least substantially to match the actual trailer travel direction with the demanded trailer travel direction.

Abstract
The present invention relates to a vehicle control system (1) for controlling a trailer (5) coupled to a vehicle (3) during a reversing operation. The vehicle control system includes a processor (29) configured to determine an actual trailer travel direction (TACT) based on one or more sensor signals. The processor (29) receives a demanded trailer travel direction (TDEM), for example from a user. A maximum permissible hitch angle (ΦMAX) is calculated by the processor (29) and the demanded trailer travel direction (TDEM) is limited to an angle less than or equal to the calculated maximum permissible hitch angle (ΦMAX). The present invention also relates to a vehicle (3) incorporating the vehicle control system (1); and a method of controlling the reversing of the trailer (5).
