Tactile control system of electronic vehicle equipment

摘要

The control system has a tactile surface and a viewing screen. The tactile surface (1) is positioned to maintain contact with hands on the vehicle steering wheel and is connected to an electronic processing device (2) which includes a first circuit (3) which acts as interface to the tactile surface (1) and which provides co-ordinates of the variable positions of a finger on the tactile surface (2). A microprocessor (4) for the finger co-ordinates, analyses and recognises symbols traced (10) by the variations in finger positions, which activate different equipment (8). A dictionary (5) of symbols is connected to the microprocessor (4). A second circuit (6) acts as a multiplexed interface which ensures communication between the microprocessor (4) and the different equipment. (8). A screen (7) is connected to the processor (4) which displays the activated control.
