System for a towing vehicle

摘要

A vehicle control system 1 is provided for controlling a trailer 5 coupled to a vehicle 3 during a reversing operation. The system includes a processor (29 see fig 2) configured to determine an actual trailer travel direction (TACT see fig 4) based on one or more sensor signals. The processor (29) receives a demanded trailer travel direction (TDEM see fig 4), for example from a user. A maximum permissible hitch angle is calculated and the demanded trailer travel direction (TDEM) is limited to an angle less than or equal to the calculated maximum permissible hitch angle. The system also estimates a distance to be travelled to match the trailer direction with the demanded direction. The invention also relates to a vehicle 3 incorporating the vehicle control system 1, and a method of controlling the reversing of the trailer 5.
