Safety device and method for avoidance of dooring injuries

1 . A safety device, comprising:

a processor, configured to:

detect from sensor data representing a vehicle occupant, whether the vehicle occupant looks for an oncoming road participant or obstacle;

operate according to a first operational mode when the processor detects that the vehicle occupant looks for an oncoming road participant or obstacle; and

operate according to a second operational mode when the processor detects that the vehicle occupant does not look for an oncoming road participant or obstacle; and

wherein detecting whether the vehicle occupant looks for an oncoming road participant or obstacle comprises the processor detecting from sensor data whether the vehicle occupant turns the vehicle occupant's torso toward a door corresponding to an interior door release.

2 . The safety device of claim 1 , further comprising a memory, configured to store data representing the detection that the occupant looked for an oncoming road participant or obstacle.

3 . The safety device of claim 1 , wherein detecting whether the vehicle occupant looks for an oncoming road participant or obstacle comprises the processor detecting whether the vehicle occupant directs the vehicle occupant's gaze in a first direction, and subsequently in a second direction, while the vehicle occupant's torso is turned toward the door.

4 . The safety device of claim 3 , wherein detecting whether the vehicle occupant directs the vehicle occupant's gaze in the first direction, and subsequently in the second direction comprises detecting whether the vehicle occupant directs the vehicle occupant's gaze through a window of the door toward the front of the vehicle and the rear of the vehicle, or through a window of the door toward the rear of the vehicle and the front of the vehicle.

5 . The safety device of claim 1 , wherein the detecting whether the vehicle occupant looks for an oncoming road participant or obstacle comprises the detecting whether the vehicle occupant performs a cross-reach maneuver;

wherein the cross-reach maneuver comprises the vehicle occupant operating the interior door release with an arm on an opposite side of the vehicle occupant's body from the interior door release.

6 . The safety device of claim 1 , wherein operating according to the first operational mode comprises the processor sending a signal to enable the interior door release.

7 . The safety device of claim 1 , wherein operating according to the second operational mode comprises the processor sending a signal to disable the interior door release.

8 . The safety device of claim 1 , wherein operating according to the second operational mode comprises the processor sending a signal to delay opening of the door for a duration after the vehicle occupant initiates the interior door release.

9 . The safety device of claim 1 , wherein operating according to the second operational mode comprises the processor sending a signal to prevent the door from opening.

10 . The safety device of claim 1 , wherein operating according to the second operational mode comprises the processor sending a signal to initiate any of an audible alarm, a visual alarm, or a haptic alarm.

11 . The safety device of claim 10 , wherein the processor initiating the visual alarm comprises the processor sending a signal to cause an overhead light to flash or a door illumination light to flash.

12 . The safety device of claim 1 , wherein the processor is further configured to detect whether the vehicle occupant is operating the interior door release; operate according to the first operational mode when the processor detects that the vehicle occupant looks for an oncoming road participant or obstacle and detects that the vehicle occupant is operating the interior door release; and operate according to the second operational mode when the processor detects that the vehicle occupant does not look for an oncoming road participant or obstacle.

13 . The safety device of claim 1 , wherein the sensor data is first sensor data;

further comprising second sensor data representing a vicinity external to the vehicle, wherein the processor is further configured to detect from the second sensor data whether an object is approaching the vehicle; and

wherein the processor is configured to operate according to the first operational mode when the processor detects that the vehicle occupant looks for an oncoming road participant or obstacle and that no object is approaching the vehicle; and

wherein the processor is configured to operate according to the second operational mode when the processor detects either of the vehicle occupant does not look for an oncoming road participant or obstacle or the processor detects an object approaching the vehicle.

14 . The safety device of claim 1 , wherein the processor is further configured to determine from the sensor data whether any persons are inside the vehicle, and if the processor detects that no persons are inside the vehicle, the processor is further configured to send an instruction to enter a standby mode or a sleep mode.

15 . A non-transitory computer readable medium, comprising instructions which, if executed, cause one or more processors to:

detect from sensor data representing a vehicle occupant, whether the vehicle occupant looks for an oncoming road participant or obstacle;

operate according to a first operational mode when the processor detects that the vehicle occupant looks for an oncoming road participant or obstacle; and

operate according to a second operational mode when the processor detects that the vehicle occupant does not look for an oncoming road participant or obstacle; and

wherein the instructions being configured to cause one or more processors to detect whether the vehicle occupant looks for an oncoming road participant or obstacle comprises the instructions being configured to cause the one or more processors to detect whether a vehicle occupant turns the vehicle occupant's torso toward a door corresponding to an interior door release.

16 . The non-transitory computer readable medium of claim 15 , wherein the instructions being configured to cause one or more processors to detect whether the vehicle occupant looks for an oncoming road participant or obstacle comprises the instructions being configured to cause one or more processors to detect whether the vehicle occupant directs the vehicle occupant's gaze in a first direction, and subsequently in a second direction, while the vehicle occupant's torso is turned toward the door.

17 . A safety device, comprising:

a processor, configured to:

detect from sensor data representing a vehicle occupant, whether the vehicle occupant looks for an oncoming road participant or obstacle;

operate according to a first operational mode when the processor detects that the vehicle occupant looks for an oncoming road participant or obstacle; and

operate according to a second operational mode when the processor detects that the vehicle occupant does not look for an oncoming road participant or obstacle; and

wherein the detecting whether the vehicle occupant looks for an oncoming road participant or obstacle comprises the detecting whether the vehicle occupant performs a cross-reach maneuver; wherein the cross-reach maneuver comprises the vehicle occupant operating the interior door release with an arm on an opposite side of the vehicle occupant's body from an interior door release; or

wherein the processor is further configured to detect whether the vehicle occupant is operating an interior door release; operate according to the first operational mode when the processor detects that the vehicle occupant looks for an oncoming road participant or obstacle and detects that the vehicle occupant is operating the interior door release; and operate according to the second operational mode when the processor detects that the vehicle occupant does not look for an oncoming road participant or obstacle.
