Abstract

According to one embodiment of the present disclosure, an autonomous vehicle includes a loader which loads a service module, a driving unit which moves an autonomous vehicle, and a controller which controls the driving unit to perform at least one of acceleration driving, turning, and stopping of the autonomous vehicle, the controller checks a driving route of the autonomous vehicle and module information of a service module and controls the driving unit based on the driving route and the module information. At least one of the autonomous vehicle of the present disclosure may be linked to or integrated with an artificial intelligence module, a drone (an unmanned aerial vehicle, UAV), a robot, augmented reality (AR), virtual reality (VR), and a device related to 5G services.

First claim

1 . A driving control method of an autonomous vehicle, comprising:
checking module information of a loaded service module; checking a driving route; and controlling a driving operation of a vehicle based on the driving route and the module information.

2 . The driving control method according to claim 1 , wherein the checking of module information includes receiving information related to at least one of a type, a size, and a weight of the service module from the service module or from a server based on a downlink grant, and
in the controlling of a driving operation, the driving operation is controlled based on at least one of the type, the size, and the weight of the service module and the driving route.

3 . The driving control method according to claim 1 , wherein the checking of module information includes checking a weight of the service module or a number of vibrations during driving through a sensor of a loader in which the service module is loaded, and
in the controlling of a driving operation, the driving operation is controlled based on the driving route and any one of the weight of the service module and the number of vibrations during driving.

4 . The driving control method according to claim 3 , wherein the controlling of a driving operation includes controlling at least one of a maximum limit value of a driving speed, a maximum limit value of a driving acceleration and the driving speed to be lowered when a magnitude or variation of the number of vibrations exceeds a set criteria.

5 . The driving control method according to claim 3 , wherein the controlling of a driving operation includes controlling the driving operation based on a possibility of a fall of the service module.

6 . The driving control method according to claim 5 , wherein the controlling of a driving operation includes controlling the driving operation to perform turning in different curved sections of a curved route at different angular velocities when the turning is necessary for the curved route of the driving route.

7 . The driving control method according to claim 6 , further comprising:
after the controlling of a driving operation, transmitting a warning message to surrounding vehicles to prevent the surrounding vehicles from entering a turning route.

8 . The driving control method according to claim 5 , wherein the controlling of a driving operation includes controlling the driving operation by driving in different sections of the driving route at different accelerations to reach a target speed if deceleration driving or acceleration driving is necessary in the driving route.

9 . The driving control method according to claim 8 , wherein the controlling of a driving operation includes controlling the driving operation by driving in different sections of the driving route alternately at acceleration and at a constant velocity to reach the target speed.

10 . The driving control method according to claim 3 , further comprising:
transmitting a module movement command to the service module to prevent a fall or collision of the service module based on the driving operation expected in accordance with the driving route.

11 . The driving control method according to claim 1 , wherein during the controlling of a driving operation, the driving operation is controlled based on the type of service articles provided by the service module, and
the driving control method of an autonomous vehicle further includes: requesting a client vehicle to change a route or a speed in order to deliver a service article to the client vehicle.

12 . A computer-readable recording medium in which a program which executes the method according to claim 1 using a computer is stored.

13 . An autonomous vehicle, comprising:
a loader which loads a service module; a driving unit which moves an autonomous vehicle; and a controller which controls the driving unit to perform at least one of acceleration driving, turning, and stopping of the autonomous vehicle, wherein the controller checks a driving route of an autonomous vehicle and module information of the service module and controls the driving unit based on the driving route and the module information.

14 . The autonomous vehicle according to claim 13 , further comprising:
a communicator which transmits/receives information with the service module or transmits/receives information with a server device based on a configured grant, wherein the controller receives the module information including information related to at least one of a type, a size, and a weight of the service module through the communicator, and the controller controls the driving unit based on at least one of the type, the size, and the weight of the service module and the driving route.

15 . The autonomous vehicle according to claim 13 , further comprising:
a sensor which is mounted in the loader to sense a weight of the service module or a number of vibrations during driving, wherein the controller controls the driving unit based on the driving route and any one of the weight of the service module and the number of vibrations during driving.

16 . The autonomous vehicle according to claim 13 , further comprising:
a communicator which transmits/receives information with the service module, wherein the controller calculates, based on a driving operation expected in accordance with the driving route, a position of the service module for preventing a fall or collision of the service module, and the communicator transmits a movement command to the service module to move to the position of the service module.

17 . The autonomous vehicle according to claim 13 , wherein when deceleration driving or acceleration driving is necessary, the controller controls to alternately drive at different accelerations to reach a target speed.

18 . The autonomous vehicle according to claim 17 , further comprising:
a distance sensor which measures a distance from a preceding vehicle, wherein the controller determines a number of changes of acceleration and a magnitude of the acceleration based on the distance from the preceding vehicle.

19 . A computer-readable recording medium in which a program which executes the method according to claim 2 using a computer is stored.

20 . A computer-readable recording medium in which a program which executes the method according to claim 3 using a computer is stored.
