System for guiding trailer along target route during reversing maneuver
First Claim
1. A system for controlling a vehicle to facilitate reversing a trailer coupled to the vehicle, the system comprising a processor configured to:
- identify permissible target trailer destinations and impermissible target trailer destinations;
receive a target trailer destination specified by a user;
determine a current trailer position;
model a target route from the current trailer position to the user-specified target trailer destination; and
output a vehicle control signal for controlling the vehicle to guide the trailer along the target route;
wherein the processor inhibits user selection of an impermissible target trailer destination.

Abstract
The present invention relates to a vehicle control system (1) for controlling a vehicle (3) to facilitate reversing a trailer (5) coupled to the vehicle (3). The vehicle control system includes a processor (33) configured to receive a target trailer destination (DTAR). The current position of the trailer (5) is determined by the processor (33). A target route (R) is then modelled to guide the trailer (5) from its current position to the target trailer destination (DTAR). The processor (33) is configured to output a vehicle control signal to control the vehicle (3) to guide the trailer (5) along the target route (R). The invention also relates to a method of controlling a vehicle (3) to facilitate reversing a trailer (5).

12. A method of controlling a vehicle to facilitate reversing a trailer to a specified target trailer destination, wherein the vehicle comprises a human machine interface (HMI) module, an electronic power assisted steering (EPAS) module, at least one camera, and a control unit having a guidance module and an image processing module, the method comprising:
-
receiving at the control unit a user input via the HMI module that defines a user-specified target trailer destination, wherein the control unit is configured to identify permissible target trailer destinations for positioning the trailer and impermissible target trailer destinations unsuitable for positioning the trailer, the control unit being configured to inhibit user selection of an impermissible target trailer destination; processing image data from the at least one camera via the image processing module to determine a current orientation of the trailer relative to the vehicle; modeling a target route from a current trailer position to the user-specified target trailer destination via the guidance module; and outputting, via the guidance module, a vehicle control signal to the EPAS module for controlling the vehicle to guide the trailer along the target route.
