Driving assistance system, vehicle and method

Abstract

A dynamic route finding system for a follower vehicle comprises a display, for disposition inside the vehicle, a navigation system, employing satellite position sensing for the vehicle, a storage device, including map data of a given territory, and an input system for the navigation system to input the location of a potentially dynamic destination of a subject (vehicle), wherein the navigation system is arranged to permit dynamic updating of the destination through said input system whilst guiding the user towards the subject from its current position. The input system may comprise an optical sensor, for front-facing disposition in the vehicle; a computer, to display on the display images captured by the optical sensor; and a user interface, enabling user commands to be input to the computer, the computer being arranged dynamically to calculate the position of a subject that is captured as an image by the optical sensing means, that has been displayed on the display, and that has been selected by the user, and to input said position as the dynamic destination of the navigation system. The input system may also comprise a telephone transceiver capable of wireless communication with another telephone, whereby the navigation system and a subject telephone may be interconnected and through which the subject telephone, when provided with a requisite application and a GPS position sensor, transmits the position of the subject telephone to the navigation system for use as the destination of the navigation system of said follower vehicle. The input system may also comprise a network of communication modules in multiple vehicles.
