## Abstract

Described herein is utilization of nontransparent Shock-Absorbing Energy Dissipation Padding (SAEDP) in an autonomous on-road vehicle. In one embodiment, the vehicle includes a side window located at eye level of an occupant who sits in the vehicle. The side window enables the occupant to see the outside environment. A motor is configured to move the SAEDP over a sliding mechanism between first and second states. A processor is configured to command the motor to move the SAEDP from the first state to the second state responsive to an indication that a probability of an imminent collision reaches a threshold. In the first state, the SAEDP does not block the occupant's eye level view to the outside environment, and in the second state, the SAEDP blocks the occupant's eye level view to the outside environment in order to protect the occupant's head against hitting the side window during collision.

## Claims

### Claim 1

An autonomous on-road vehicle, comprising:
a side window located at eye level of an occupant who sits in the vehicle; whereby the window enables the occupant to see the outside environment;
a nontransparent Shock-Absorbing Energy Dissipation Padding (SAEDP);
a motor configured to move the SAEDP between first and second states multiple times without having to be repaired; and
a processor configured to receive an indication that a probability of an imminent collision reaches a threshold, and to command the motor to move the SAEDP from the first state to the second state; wherein in the first state the SAEDP does not block the occupant's eye level view to the outside environment, and in the second state the SAEDP blocks the occupant's eye level view to the outside environment in order to protect the occupant's head against hitting the side window during collision.

### Claim 2 (depends on 1)

The autonomous on-road vehicle of claim 1, wherein the processor is configured to receive from an autonomous-driving control system the indication that the probability of the imminent collision reaches the threshold, and the processor is further configured to receive an updated indication that the probability of the imminent collision does not reach a second threshold, and to command the motor to move the SAEDP to the first state; whereby the second threshold denotes a probability for a collision that is equal or lower than the threshold.

### Claim 3 (depends on 1)

The autonomous on-road vehicle of claim 1, wherein the motor is configured to move the SAEDP over a sliding mechanism, and the processor is configured to command the motor to start moving the SAEDP to the second state at least 0.2 second before the collision.

### Claim 4 (depends on 3)

The autonomous on-road vehicle of claim 3, further comprising a display configured to present to the occupant a video of the threat in order to explain why the SAEDP moved to the second state.

### Claim 5 (depends on 1)

The autonomous on-road vehicle of claim 1, wherein the side window is a power window; the power window comprises a window regulator that transfers power from a window motor to the side window glass in order to move it up or down; and wherein the SAEDP is coupled to an SAEDP regulator that transfers power from an SAEDP motor to the SAEDP in order to move it up or down; wherein the SAEDP regulator is located closer to the inner side of the compartment relative to the window regulator.

### Claim 6 (depends on 1)

The autonomous on-road vehicle of claim 1, wherein the SAEDP comprises a passive material, which is less stiff than a standard automotive glass window; and wherein the passive material has a thickness ranging from 1 cm to 15 cm.

### Claim 7 (depends on 1)

The autonomous on-road vehicle of claim 1, further comprising a camera configured to take video of the outside environment while the 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.

### Claim 8 (depends on 7)

The autonomous on-road vehicle of claim 7, wherein the camera is coupled to the SAEDP, and thus moves with the SAEDP when it is moved between the first and second states.

### Claim 9 (depends on 7)

The autonomous on-road vehicle of claim 7, wherein the display is coupled to the SAEDP, and thus moves with the SAEDP when it is moved between the first and second states.

### Claim 10 (depends on 9)

The autonomous on-road vehicle of claim 9, wherein the display is a flexible display that is configured to show, at eye level, a representation of the outside environment when the SAEDP is in the second state.

### Claim 11 (depends on 7)

The autonomous on-road vehicle of claim 7, wherein the camera comprises multiple cameras directed to multiple directions around the vehicle, and the computer is configured to generate at least two different representations of the outside environment, from at least two different points of view, for two occupants who sit in the vehicle.

### Claim 12 (depends on 1)

The autonomous on-road vehicle of claim 1, wherein the SAEDP moves upwards when switching from the first state to the second state, and the top of the SAEDP has a shape in the form of a triangle or a quarter circle; whereby said shape reduces the risk of squeezing the occupant's fingers or limb between the top of the SAEDP and an upper frame when moving the SAEDP to the second state.

### Claim 13 (depends on 1)

The autonomous on-road vehicle of claim 1, wherein when moving the SAEDP quickly from the first state to the second state, the SAEDP is configured not to cover a range of 1 to 5 cm of the top height of the window; whereby said range reduces the risk of squeezing the occupant's fingers or limb by the edge of the SAEDP when moving the SAEDP to the second state.

### Claim 14 (depends on 1)

The autonomous on-road vehicle of claim 1, further comprising a storage space in a door of the vehicle; wherein the storage space is configured to store the SAEDP in the first state.

### Claim 15 (depends on 1)

The autonomous on-road vehicle of claim 1, further comprising a storage space in the roof of the vehicle; wherein the storage space is configured to store the SAEDP in the first state.

### Claim 16

An autonomous on-road vehicle, comprising:
a compartment;
a nontransparent Shock-Absorbing Energy Dissipation Padding (SAEDP) that is coupled to the compartment and is located, during normal driving, at eye level to the left of the occupant who sits in a front seat of the vehicle; wherein the SAEDP obstructs at least 30 degrees out of the horizontal unaided field of view (FOV) to the outside environment to the left of the occupant at eye level;
a stiff element configured to support the SAEDP and to resist deformation during collision in order to reduce compartment intrusion; wherein the stiff element is located, during normal driving, at eye level between the SAEDP and the outside environment;
a camera configured to take video of the outside environment to the left of the occupant; and
a computer configured to generate, based on the video, a representation of the outside environment to the left of the occupant at eye level.

### Claim 17 (depends on 16)

The autonomous on-road vehicle of claim 16, wherein the SAEDP is fixed to the left door of the vehicle, and the vehicle has just one seat, or the vehicle has two front seats and the occupant sits in the left front seat.

### Claim 18 (depends on 16)

The autonomous on-road vehicle of claim 16, wherein the SAEDP comprises a passive material, which is less stiff than a standard automotive glass window; and wherein the passive material has a thickness ranging from 1 cm to 15 cm.

### Claim 19 (depends on 16)

The autonomous on-road vehicle of claim 16, wherein the SAEDP obstructs at least 45 degrees out of the horizontal unaided FOV to the outside environment to the left of the occupant at eye level.

### Claim 20 (depends on 16)

The autonomous on-road vehicle of claim 16, further comprising a second SAEDP located at eye level to the right of the occupant who sits in the front seat, and a second stiff element located at eye level between the second SAEDP and the outside environment; wherein the second SAEDP obstructs at least 20 degrees out of the horizontal unaided FOV to the outside environment to the right of the occupant at eye level, and the computer is further configured to generate a second representation of the outside environment to the right of the occupant.
