Abstract

An autonomous on-road vehicle having an outer nontransparent Shock-Absorbing Energy Dissipation Padding (SAEDP). In one embodiment, the SAEDP is mounted, during normal driving, to the front side of the vehicle at eye level of an occupant who sits in a front seat of the vehicle. A camera is mounted to the vehicle and takes video of the outside environment in front of the occupant. And a computer generates a representation of the outside environment at eye level for the occupant.

Claims

1. An autonomous on-road vehicle comprising:

an outer nontransparent Shock-Absorbing Energy Dissipation Padding (outer nontransparent SAEDP) mounted, during normal driving, to the front side of the vehicle at eye level of an occupant who sits in a front seat of the vehicle;

a camera mounted to the vehicle and configured to take video of the outside environment in front of the occupant; and

a computer configured to generate, based on the video, a representation of the outside environment at eye level for the occupant.

2. The autonomous on-road vehicle of claim 1, wherein the outer nontransparent SAEDP is less stiff than a standard automotive glass window and is designed to absorb some of the crashing energy transmitted to a pedestrian during a pedestrian-vehicle collision.

3. The autonomous on-road vehicle of claim 1, wherein the outer nontransparent SAEDP comprises a passive material.

4. The autonomous on-road vehicle of claim 3, wherein the outer nontransparent SAEDP has thickness greater than 5 cm.

5. The autonomous on-road vehicle of claim 1, wherein the outer nontransparent SAEDP comprises an automotive airbag configured to inflate in order to protect the pedestrian.

6. The autonomous on-road vehicle of claim 5, wherein the airbag has a stowed condition and an inflated condition;

the airbag is coupled to an inflator configured to inflate the airbag with gas, and the airbag is located, in the stowed condition, at eye level in front of the occupant; and

further comprising an autonomous-driving control system configured to calculate probability of pedestrian-vehicle collision, based on measurements of sensors mounted on the vehicle, and to command the airbag to inflate before the pedestrians head hits the vehicle.

7. The autonomous on-road vehicle of claim 1, wherein the outer nontransparent SAEDP comprises a pneumatic pad configured to inflate in order to protect the pedestrian, and further comprising an autonomous-driving control system configured to calculate probability of pedestrian-vehicle collision, based on measurements of sensors mounted on the vehicle, and to command the pneumatic pad to start inflate at least 0.5 second before the crash in order to protect the pedestrian.

8. The autonomous on-road vehicle of claim 7, wherein the pneumatic pad is reusable.

9. The autonomous on-road vehicle of claim 1, wherein the representation is generated from the point of view of the occupant, and further comprising a display configured to present the representation to the occupant.

10. An autonomous on-road vehicle comprising:

an outer nontransparent Shock-Absorbing Energy Dissipation Padding (outer nontransparent SAEDP) stored above or below a windshield located at eye level in front of an occupant who sits in a front seat of the vehicle;

a motor configured to move the outer nontransparent SAEDP between a first state, in which the outer nontransparent SAEDP does not block the occupant'"'"'s eye level frontal view to the outside environment, and a second state, in which the outer nontransparent SAEDP blocks the occupant'"'"'s eye level frontal view to the outside environment, multiple times without having to be repaired; and

a processor configured to receive an indication that a probability of an imminent pedestrian-vehicle collision reaches a threshold, and to command the motor to move the outer nontransparent SAEDP from the first state to the second state.

11. The autonomous on-road vehicle of claim 10, wherein the outer nontransparent SAEDP is less stiff than a standard automotive glass window, and in the second state the outer nontransparent SAEDP is configured to absorb some of the crashing energy transmitted to a pedestrian during a pedestrian-vehicle collision.

12. The autonomous on-road vehicle of claim 10, wherein the processor is further configured to receive an updated indication that the probability of the imminent pedestrian-vehicle collision does not reach a second threshold, and to command the motor to move the outer nontransparent SAEDP to the first state;

wherein the second threshold is lower than the threshold, and the processor receives at least one of the indication and the updated indication from an autonomous-driving control system.

13. The autonomous on-road vehicle of claim 10, wherein the motor is configured to move the outer nontransparent SAEDP over a sliding mechanism, and the processor is configured to command the motor to start moving the outer nontransparent SAEDP to the second state at least 1 second before the pedestrian-vehicle collision in order to protect the pedestrian.

14. The autonomous on-road vehicle of claim 10, wherein the outer nontransparent SAEDP comprises a pneumatic pad configured to inflate in order to protect the pedestrian.

15. The autonomous on-road vehicle of claim 14, wherein the pneumatic pad is reusable, and the processor is configured to command the pneumatic pad to start inflate at least 0.5 second before the pedestrian-vehicle collision.

16. The autonomous on-road vehicle of claim 10, wherein the outer nontransparent SAEDP comprises a passive material having thickness greater than 1 cm.

17. The autonomous on-road vehicle of claim 10, further comprising a camera configured to take video of the outside environment while the outer nontransparent SAEDP is in the second state, a computer configured to generate a representation of the outside environment based on the video, and a display configured to present the representation of the outside environment to the occupant while the outer nontransparent SAEDP is in the second state.

18. The autonomous on-road vehicle of claim 17, wherein the camera is fixed to the outer nontransparent SAEDP, and thus moves with the outer nontransparent SAEDP when it is moved between the first and second states.

19. The autonomous on-road vehicle of claim 17, wherein the display is fixed to the outer nontransparent SAEDP from the inner side, and thus moves with the outer nontransparent SAEDP when it is moved between the first and second states;

whereby the occupant can watch the display via the windshield when the outer nontransparent SAEDP is in the second state.

20. The autonomous on-road vehicle of claim 17, wherein the display is at least one of the following displays:

a display that is physically coupled to the compartment of the autonomous on-road vehicle, and a display comprised in a head-mounted display.
