Abstract

Methods and apparatus pertaining to an intelligent vehicle access point opening system are provided. A method may involve detecting a presence of an object in a vicinity of a cover of an access point of a vehicle. The method may also involve receiving a command to open the cover and activating a mechanism to open the cover responsive to receiving the command. The method may further involve determining whether the object is likely to fall as the cover is being opened. The method may additionally involve pausing opening of the cover responsive to a determination that the object is likely to fall as the cover is being opened.

First claim

The invention claimed is:

1. An apparatus implementable in a vehicle, comprising:
one or more sensors configured to detect a presence of an object in a vicinity of a cover of an access point of the vehicle and inside the vehicle, the one or more sensors also configured to output data related to the detecting;
a mechanism configured to open and close the cover; and
a controller communicatively coupled to the one or more sensors and the mechanism, the controller configured to perform operations comprising:
receiving a command to open the cover;
activating the mechanism to open the cover responsive to receiving the command;
determining whether the object is likely to fall from inside the vehicle to outside the vehicle after the cover has been at least partially opened by:
measuring a relative distance between the object and a sensor on the cover as the cover is being opened; and
determining, based on the relative distance, whether the object is stationary and whether the object is non-stationary and moving toward the cover as the cover is being opened; and

pausing opening of the cover based on determining that the object is likely to fall based on determining that the object is non-stationary and moving toward the cover as the cover was being opened.

2. The apparatus of claim 1 , wherein the one or more sensors comprise one or more ultrasound sensors.

3. The apparatus of claim 2 , in determining whether the object is likely to fall from inside the vehicle to outside the vehicle as the cover is being opened, the controller is configured to determine whether a distance between the one or more ultrasound sensors and the object is increasing in a mathematically-defined way as the cover is being opened, and wherein, in pausing the opening of the cover responsive to a determination that the object is likely to fall as the cover is being opened, the controller is configured to pause the opening of the cover responsive to a determination that the distance between the one or more ultrasound sensors and the object is not increasing in the mathematically-defined way as the cover is being opened.

4. The apparatus of claim 2 , wherein, in determining whether the object is likely to fall from inside the vehicle to outside the vehicle as the cover is being opened, the controller is configured to determine a distance between the one or more ultrasound sensors and the object as the cover is being opened, and wherein, in pausing the opening of the cover responsive to a determination that the object is likely to fall as the cover is being opened, the controller is configured to pause the opening of the cover responsive to the determined distance being less than a predetermined threshold distance.

5. The apparatus of claim 1 , wherein the one or more sensors comprise one or more force sensors and at least one sensor of a different type.

6. The apparatus of claim 5 , wherein, in determining whether the object is likely to fall from inside the vehicle to outside the vehicle as the cover is being opened, the controller is configured to determine that the object is likely to fall responsive to the one or more force sensors and the at least one sensor of the different type detecting the presence of the object as the cover is being opened.

7. The apparatus of claim 1 , wherein, in detecting the presence of the object, the controller is configured to perform operations comprising:
detecting an amount of force used by the mechanism to open the cover; and
determining whether the detected amount of force is different from a predetermined amount of force.

8. The apparatus of claim 7 , wherein the controller is further configured to perform operations comprising:
detecting the presence of the object in an event that the detected amount of force is less than the predetermined amount of force.

9. The apparatus of claim 1 , wherein the mechanism comprises an electric motor, a pneumatic actuator, a hydraulic actuator, or a combination thereof.

10. The apparatus of claim 1 , wherein the controller is further configured to perform operations comprising:
moving the cover in a closing direction by at least a predefined distance; and
providing a notification to a user of the vehicle.

11. A method, comprising:
activating a mechanism to open a cover of an access point of a vehicle;
determining whether an object inside the vehicle is likely to fall from inside the vehicle to outside the vehicle after the cover has been at least partially opened by:
measuring a relative distance between the object and a sensor on the cover as the cover is being opened; and
determining, based on the relative distance, whether the object is stationary and whether the object is non-stationary and moving toward the cover as the cover is being opened; and

pausing opening of the cover based on determining that the object is likely to fall responsive to a determination that the object is non-stationary and moving toward the cover as the cover was being opened.

12. The method of claim 11 , wherein the activating of the mechanism to open the cover comprises activating an electric motor, a pneumatic actuator, a hydraulic actuator, or a combination thereof to open the cover.

13. The method of claim 11 , further comprising:
detecting a presence of the object in the vicinity of the cover and inside the vehicle;
receiving a command to open the cover;
moving the cover in a closing direction by at least a predefined distance; and
providing a notification to a user of the vehicle.

14. The method of claim 13 , wherein the sensor comprises one or more ultrasound sensors, and wherein the detecting of the presence of the object comprises detecting the presence of the object using the one or more ultrasound sensors.

15. The method of claim 14 , wherein the determining of whether the object is likely to fall from inside the vehicle to outside the vehicle after the cover has been at least partially opened comprises determining whether a distance between the one or more ultrasound sensors and the object is increasing in a mathematically-defined way as the cover is being opened, and wherein the pausing of the opening of the cover responsive to a determination that the object is likely to fall as the cover is being opened comprises pausing the opening of the cover responsive to a determination that the distance between the one or more ultrasound sensors and the object is not increasing in the mathematically-defined way as the cover is being opened.

16. The method of claim 14 , wherein the determining of whether the object is likely to fall from inside the vehicle to outside the vehicle after the cover has been at least partially opened comprises determining a distance between the one or more ultrasound sensors and the object as the cover is being opened, and wherein the pausing of the opening of the cover responsive to a determination that the object is likely to fall as the cover is being opened comprises pausing the opening of the cover responsive to the determined distance being less than a predetermined threshold distance.

17. The method of claim 13 , wherein the sensor comprises one or more force sensors, and wherein the detecting of the presence of the object comprises detecting the presence of the object using the one or more force sensors and at least one sensor of a different type.

18. The method of claim 17 , wherein the determining of whether the object is likely to fall from inside the vehicle to outside the vehicle after the cover has been at least partially opened comprises determining that the object is lik
