Abstract

Claims (36)

1 . An autonomous vehicle (AV) intelligent driving system (IDS), comprising:

a sensing module provided in an AV, said sensing module collecting driving environment information; and

an onboard unit (OBU) provided in the AV, said OBU comprising:

1) a vehicle control module operating and/or controlling the AV;

2) a traffic control center/traffic control unit (TCC/TCU) communication module communicating with a TCC/TCU and receiving vehicle-specific targeted guidance instructions and information at a Guidance Level of vehicle driving tasks from the TCC/TCU,

wherein the sensing module fuses data from a plurality of sensors and uses a backup plan if a sensor of the plurality of sensors has a functional problem; and

wherein the vehicle control module controls the AV using the driving environment information collected by said sensing module, and the vehicle-specific guidance instructions and information provided by the TCC/TCU.

2 . The AVIDS of claim 1 , wherein said guidance instructions and information at the Guidance Level of vehicle driving tasks comprise: vehicle maneuver, safety maintenance, traffic control/road condition, and special information.

3 . The AVIDS of claim 2 , wherein said vehicle maneuver comprises car following, speed/headway keeping, position in lane keeping, lane changing, horizontal alignment and changes, and/or vertical alignment and changes.

4 . The AVIDS of claim 2 , wherein said safety maintenance comprises speed limit maintenance, entrance/exit control, and/or headway maintenance.

5 . The AVIDS of claim 2 , wherein said traffic control/road condition comprises traffic control information and road surface condition.

6 . The AVIDS of claim 2 , wherein said special information comprises climatological conditions, activity, accidents, and/or hazards/obstacles.

7 . The AVIDS of claim 1 , wherein said TCC/TCU sends guidance instructions and information to a roadside unit (RSU) and said RSU sends the guidance instructions and information to the AV.

8 . The AVIDS of claim 1 , wherein said AV and said TCC/TCU fulfill driving tasks together and use each other as a backup in case of an error or failure.

9 . The AVIDS of claim 1 , configured to:

receive vehicle-specific guidance instructions and information from the TCC/TCU; and

control, by the vehicle control module, an AV comprising said AVIDS using said vehicle-specific guidance instructions and information.

10 . A connected and automated vehicle (CAV), comprising the AVIDS of claim 1 .

11 . An autonomous vehicle (AV) intelligent driving system (IDS), comprising:

a sensing module provided in an AV, said sensing module collecting driving environment information; and

an onboard unit (OBU) provided in the AV, said OBU comprising:

1) a vehicle control module operating and/or controlling the AV;

2) a roadside unit (RSU) communication module, said RSU communication module communicating with one or more RSU and receiving vehicle-specific targeted guidance instructions and information at a Guidance Level of vehicle driving tasks from said one or more RSU;

wherein the sensing module fuses data from a plurality of sensors and uses a backup plan if a sensor of the plurality of sensors has a functional problem; and

wherein the vehicle control module controls the AV using the driving environment information collected by said sensing module, and the vehicle-specific targeted guidance instructions and information provided by one or more RSU.

12 . The AVIDS of claim 11 , wherein said guidance instructions and information at the Guidance Level of vehicle driving tasks comprise: vehicle maneuver, safety maintenance, traffic control/road condition, and special information.

13 . The AVIDS of claim 12 , wherein said vehicle maneuver comprises car following, speed/headway keeping, position in lane keeping, lane changing, horizontal alignment and changes, and/or vertical alignment and changes.

14 . The AVIDS of claim 12 , wherein said safety maintenance comprises speed limit maintenance, entrance/exit control, and/or headway maintenance.

15 . The AVIDS of claim 12 , wherein said traffic control/road condition comprises traffic control information and road surface condition.

16 . The AVIDS of claim 12 , wherein said special information comprises climatological conditions, activity, accidents, and/or hazards/obstacles.

17 . The AVIDS of claim 11 , wherein said RSU receives the guidance instructions and information from a TCC/TCU and sends the guidance instructions and information to an AV.

18 . The AVIDS of claim 11 , wherein said AV and said RSU fulfill driving tasks together and use each other as a backup in case of an error or failure.

19 . The AVIDS of claim 11 , configured to:

receive vehicle-specific guidance instructions and information from said one or more RSU; and

control, by the vehicle control module, an AV comprising said AVIDS using said vehicle-specific guidance instructions and information.

20 . A connected and automated vehicle (CAV), comprising the AVIDS according to claim 11 .
