Infotelematic system for a road vehicle

59) The infotelematic system (1) according to claim 1, wherein the control device (8) comprises four pushbuttons (33), which are provided on the top surface (31) of the plane plate (30), are made of touch-sensitive material, and are symmetrically arranged in the four quadrants defined by the first cross-shaped path (32);

• the first sensor device (35) coupled to the plane plate (30) being designed to detect a tactile pressure on each pushbutton (33).

60) The infotelematic system (1) according to claim 1, wherein the control device (8) comprises the first cross-shaped path (32) is highlighted by means of a differentiation of colouring and/or a differentiation of height with respect to the rest of the top surface (31) of the plane plate (30).

61) The infotelematic system (1) according to claim 1, wherein the plane plate (30) has at the top an aluminium plate that constitutes the top surface (31) of the plane plate (30).

62) The infotelematic system (1) according to claim 1, wherein the first sensor device (35) comprises a piezoelectric film.

63) The infotelematic system (1) according to claim 1, wherein the first sensor device (35) comprises a capacitive film.

64) The infotelematic system (1) according to claim 1, wherein reproduced on the display (7) is a synoptic image (39) that reproduces the shape of the control device (8) indicating the functions associated to the control device (8) itself.

66) The infotelematic system (1) according to claim 8, wherein the control device (8) comprises a haptic actuator, which is coupled to the slider (36) for varying the force necessary to displace the slider (36) itself along the circular closed path (34).

67) The infotelematic system (1) according to claim 8, wherein the control device (8) comprises:

• a number of pushbuttons (33), which are provided on the top surface (31) of the plane plate (30), are made of touch-sensitive material, and are arranged within the first circular closed path (34);
• and
• a second sensor device (35) coupled to the plane plate (30) for detecting a tactile pressure on each pushbutton (33).

68) The infotelematic system (1) according to claim 10, wherein the plane plate (30) has at the top an aluminium plate that constitutes the top surface (31) of the plane plate (30).

69) The infotelematic system (1) according to claim 10, wherein the second sensor device (35) comprises a piezoelectric film.

70) The infotelematic system (1) according to claim 10, wherein the second sensor device (35) comprises a capacitive film.

71) The infotelematic system (1) according to claim 8, wherein reproduced on the display (7) is a synoptic image (39) that reproduces the shape of the control device (8) indicating the functions associated to the control device (8) itself.

73) The control method according to claim 15, comprising the further step of governing the haptic actuator (16) coupled to the bar (9) so as to require a peak of effort for abandoning a position of selection corresponding to a respective selectable option (18).

74) The control method according to claim 15, wherein in the arc of movement of the bar (9) downwards a further end selection position is inserted, which is set in the bottom end position and corresponds to an option of return to a top menu.

75) The control method according to claim 15, comprising the further step of displaying on the display (7) a selection cursor (20), which is displaced by the movement of the bar (9) and indicates a current position of selection.

76) The control method according to claim 18, comprising the further steps of:

• detecting the pressure upon an activation pushbutton (17) mounted on the bar (9);
• and
• selecting the option (18) corresponding to the position in which the selection cursor (20) is set at the moment when the activation pushbutton (17) is pressed.
