Abstract

A system that performs a method is disclosed. The system operates a vehicle in a first automation level corresponding to a first plurality of modes for operating the vehicle. The first plurality of modes comprises logic for performing automated driving operations, wherein the first automation level is associated with a first logic for transitioning between the first plurality of modes. While operating the vehicle in the first automation level, the system determines that automation level change criteria for transitioning from the first automation level to a second automation level are satisfied. In response to the determination, the system operates the vehicle in the second automation level corresponding to a second plurality of modes for operating the vehicle. The second plurality of modes comprises logic for performing automated driving operations, wherein the second automation level is associated with a second logic for transitioning between the second plurality of modes.

First claim

1 . A system comprising:
one or more processors; and a memory including instructions, which when executed by the one or more processors, cause the one or more processors to perform a method comprising: operating a vehicle in a first automation level, the first automation level corresponding to a first plurality of modes for operating the vehicle, the first plurality of modes comprising logic for performing one or more automated driving operations, wherein the first automation level is associated with a first logic for transitioning between the first plurality of modes; while operating the vehicle in the first automation level, determining that automation level change criteria for transitioning from the first automation level to a second automation level, different from the first automation level, are satisfied; and in response to the determination, operating the vehicle in the second automation level, the second automation level corresponding to a second plurality of modes for operating the vehicle, the second plurality of modes comprising logic for performing one or more automated driving operations, wherein the second automation level is associated with a second logic, different from the first logic, for transitioning between the second plurality of modes.

2 . The system of claim 1 , wherein determining that the automation level change criteria for transitioning from the first automation level to the second automation level are satisfied is based on driver input.

3 . The system of claim 1 , wherein determining that the automation level change criteria for transitioning from the first automation level to the second automation level are satisfied is based on map information.

4 . The system of claim 1 , wherein determining that the automation level change criteria for transitioning from the first automation level to the second automation level are satisfied is based on characteristics in the vehicle's surroundings.

5 . The system of claim 1 , wherein the method further comprises in response to the determination that the automation level change criteria for transitioning from the first automation level to the second automation level are satisfied, notifying the driver of the determination.

6 . The system of claim 5 , wherein the driver confirms or rejects operating the vehicle in the second automation level.

7 . The system of claim 1 , wherein:
the first logic for transitioning between the first plurality of modes comprises logic for automatic transitions between the first plurality of modes; and the second logic for transitioning between the second plurality of modes comprises logic for automatic and manual transitions between the second plurality of modes.

8 . The system of claim 7 , wherein:
the first logic and the second logic for automatic transitions are based on characteristics in the vehicle's surroundings; and the second logic for manual transitions are based on driver input.

9 . The system of claim 1 , wherein:
the first logic for transitioning between the first plurality of modes comprises logic for automatic transitions between the first plurality of modes based on characteristics in the vehicle's surroundings; and the second logic for transitioning between the second plurality of modes comprises logic for manual transitions between the second plurality of modes based on driver input.

10 . The system of claim 1 , wherein the method further comprises:
while operating the vehicle in the second automation level, determining that respective automation level change criteria for transitioning from the second automation level to a respective automation level are satisfied; and in accordance with a determination that the respective automation level change criteria comprise automation level change criteria for transitioning from the second automation level to a third automation level, operating the vehicle in the third automation level, different from the first and second automation levels; and in accordance with a determination that the respective automation level change criteria comprise automation level change criteria for transitioning from the second automation level to the first automation level, operating the vehicle in the first automation level.

11 . The system of claim 10 , wherein:
the third automation level corresponds to a third plurality of modes for operating the vehicle, the third plurality of modes comprising logic for performing one or more automated driving operations; and the third automation level is associated with a third logic, different from the first logic and the second logic, for manually transitioning between the third plurality of modes.

12 . The system of claim 2 , wherein the third automation level comprises logic for operating the vehicle through drive-by-wire driving operation instructions entered by the driver.

13 . The system of claim 10 wherein the method further comprises:
while operating the vehicle in the respective automation level, determining that respective automation level change criteria for exiting vehicle automation are satisfied; and
in accordance with a determination that the respective automation level change criteria comprise automation level change criteria for transitioning from the respective automation level to alert the driver that the vehicle is exiting vehicle automation, alerting the driver that the vehicle is exiting the respective automation level, exiting the respective automation level, and enabling the driver to manually take over driving operations after performing the alert;
in accordance with a determination that the respective automation level change criteria comprise automation level change criteria for transitioning from the respective automation level to enable the driver to manually take over driving operations, exiting the respective automation level and enabling the driver to manually take over driving operations; and
in accordance with a determination that the respective automation level change criteria comprise automation level change criteria for transitioning from the respective automation level to disabling the vehicle, exiting the respective automation level and disabling the vehicle.

14 . The system of claim 13 , wherein determining that the respective automation level change criteria are satisfied is based on characteristics about the vehicle's surroundings.

15 . The system of claim 13 , wherein determining that the respective automation level change criteria are satisfied is based on map information.

16 . A vehicle comprising:
one or more processors; and a memory including instructions, which when executed by the one or more processors, cause the one or more processors to perform a method comprising: operating the vehicle in a first automation level, the first automation level corresponding to a first plurality of modes for operating the vehicle, the first plurality of modes comprising logic for performing one or more automated driving operations, wherein the first automation level is associated with a first logic for transitioning between the first plurality of modes; while operating the vehicle in the first automation level, determining that automation level change criteria for transitioning from the first automation level to a second automation level, different from the first automation level, are satisfied; and in response to the determination, operating the vehicle in the second automation level, the second automation level corresponding to a second plurality of modes for operating the vehicle, the second plurality of modes comprising logic for performing one or more
