INFOTELEMATIC SYSTEM FOR A ROAD VEHICLE

摘要

A method for control of an infotelematic system (1) for a road vehicle for choosing from amongst a number of selectable options (18); the control method presenting the steps of: displaying on a display (7) a set of selectable options (18) ordered so as to form a vertical list; detecting the position of a bar (9) of a control device (8) of the joystick type for determining the option (18) selected by the user; identifying a central position in the list of the selectable options (18); dividing the selectable options (18) into a top halflist set above the central position and a bottom halflist set below the central position; and governing a haptic actuator (16) coupled to the bar (9) to allow the bar (9) to perform only vertical movements downwards and upwards starting from a central position of the bar (9), and dividing each arc of movement of the bar (9) downwards or upwards into a plurality of positions of selection, which are set at an angular distance from one another and each of which corresponds to a respective selectable option (18) of a respective bottom or top halflist.
