The present invention relates to a vehicle control system (1) for controlling a vehicle (3) to facilitate parking a trailer (5) coupled to the vehicle (3). The vehicle control system includes a processor (33) configured to identify a target parking destination (PTAR) for the trailer (5). 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 parking destination (PTAR). 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).
