Abstract

Apparatus (25, 30-33) for electronic rearward vision in motor vehicles (10) comprising a kinescope (25) placed centrally on the instrument panel (11) and the device with iconoscope (30-33) placed at the sides of the vehicle (10) and facing towards the rear, shaped and situated so as substantially to constitute lateral and rear “eyes” for the driver (50), whereby forward and reversing movements, especially when parking, are facilitated in that use of the kinescope (25) obviates any need to turn head and shoulders in order to observe available space around the vehicle (10) and to be aware of changes in such space caused by movement of the driver'"'"'s own vehicle and by others.

Claims

1. Apparatus (25, 26, 28, 30-33, 41-43, 60-63) for electronic rearward vision in motor vehicles (10),

characterized in that it comprises a kinescope (25) placed centrally on the instrument panel (11), and device with iconoscope (30-33), placed laterally and facing towards the rear of the motor vehicle (10), and on the rear itself, so situated as substantially to form lateral and rearward “

eyes”

for the driver (50) so that, during forward movement, without turning his head and shoulders, he not only keeps a continuous watch on the space in front but also, observing the kinescope (25), can view the whole area surrounding the vehicle (10) and therefore note changes in the space available, caused both by movement of his own vehicle as well as by that of other vehicles and, when reversing the vehicle, be able to see how much space is available at the side as well as in front, of particular advantage when parking.

2. Apparatus (25,26, 28, 30-33, 41-43, 60-63) for electronic rearward vision in motor vehicles (10) as in claim 1, characterized in that the device with iconoscope (32, 33) is placed on the sides of the motor vehicle (10) towards the rear.

3. Apparatus (25,26, 28, 30-33, 41-43, 60-63) for electronic rearward vision in motor vehicles (10) as in claim 1, characterized in that there is one device with iconoscope (32,33) for each side of the vehicle.

4. Apparatus (25,26, 28, 30-33, 41-43, 60-63) for electronic rearward vision in motor vehicles (10) as in claim 1, characterized in that there are two devices with iconoscope (32,33) for each side of the vehicle, and two (30, 31) on the rear.

5. Apparatus (25,26, 28, 30-33, 41-43, 60-63) for electronic rearward vision in motor vehicles (10) as in claim 1, characterized in that each device (30-33) comprises an objective (41), an iconoscope (42), and the electronic system (43).

6. Apparatus (25,26, 28, 30-33, 41-43, 60-63) for electronic rearward vision in motor vehicles (10), as in claim 5, characterized in that the objective (41) is wide-angled.

7. Apparatus (25,26, 28, 30-33, 41-43, 60-63) for electronic rearward vision in motor vehicles (10) as in claim 1, characterized in that the kinoscope (25) with related electronics (26) and the other electronic components including those for the various devices with iconoscope (30-33), such as power feed, are placed on the instrument panel (11).

8. Apparatus (25,26, 28, 30-33, 41-43, 60-63) for electronic rearward vision in motor vehicles (10), as in claim 1,

characterized in that the kinescope (25) is situated centrally on the instrument panel (11), partially extending as far as the bottom of the windshield (18) but without reaching the lower limit of the optic cone (70) projecting from the eyes (51) of the driver (50) forward of the vehicle (10) keeping in line with the top (15) of the bonnet (14).

9. Apparatus (25,26, 28, 30-33, 41-43, 60-63) for electronic rearward vision in motor vehicles (10) as in claims 1 and 7,

characterized in that the devices with iconoscope (30-33) are placed so as to transmit a substantially panoramic view (70, 72) to the electronic system (26) of the kinoscope (25), to show the space at the sides and rear of the motor vehicle (10).

10. Apparatus (25, 26, 28, 30-33, 41-43, 60-63) for electronic rearward vision in motor vehicles (10), as in claims 6 and 7,

characterized in that the electronic system (26) of the kinoscope (25) for reconversion of electric signals sent out by the electronics (43) in the devices with iconoscope (30-33), into pictures, comprises a process control computer to provide an overall view of space at the side and back of the vehicle, correcting any superimposition, interruption and other irregularities as and when they occur.

11. Apparatus (25, 2628, 30-33, 41-43, 60-63) for electronic rearward vision in motor vehicles (10) as in claims 1 and 10,

characterized in that the process control computer corrects deflection in images caused by the fact that the kinoscope (25) faces the same way as the objectives (41).

12. Apparatus (25, 26, 28, 30-33, 41-43, 60-63) for electronic rearward vision in motor vehicles (10) as in claim 1,

characterized in that the device with iconoscope (30-33) is protectively housed in a recess closed by a door flap (45), there being motor-driven means that automatically open said door flap (45), when the vehicle is started, permitting said device with iconoscope (30-33) to assume its correct operative position.

13. Apparatus (25, 26, 28, 30-33, 41-43, 60-63) for electronic rearward vision in motor vehicles (10) as in claim 1,

characterized in that the kinescope (25) can also serve for navigation by satellite, using the control (28) for the purpose.

14. Apparatus (25, 26, 28, 30-33, 41-43, 60-33) for electronic rearward vision in motor vehicles (10) as in claim 1,

characterized in that the kinescope (25) can also serve to provide the driver with any other useful indications.
