Abstract

The present disclosure provides a server, a remote control device and a remote control method for an automatic driving vehicle. The method includes: after receiving a remote control request of an automatic driving vehicle, determining a control instruction according to the remote control request, and transmitting the control instruction by using wireless channels corresponding to a plurality of wireless networks.

First claim

What is claimed is:

1. A remote control method for an automatic driving vehicle, applied to a server and comprising:
receiving a remote control request transmitted by an automatic driving vehicle;
determining a control instruction based on information carried by the remote control request;
acquiring current geographic location information of the automatic driving vehicle based on the information carried by the remote control request;
acquiring a time when the remote control request is received by the server that communicates with the automatic driving vehicle via wireless networks;
determining a plurality of target wireless networks corresponding to the current geographic location information based on a pre-stored correspondence between geographic locations and the wireless networks, and determining a plurality of target wireless channels corresponding to the plurality of target wireless networks based on the time; and
transmitting the control instruction to the automatic driving vehicle by using the plurality of target wireless channels corresponding to the plurality of target wireless networks.

2. The method according to claim 1 , further comprising:
acquiring current geographic location information of the automatic driving vehicle based on the information carried by the remote control request; and
screening the plurality of wireless networks according to the current geographic location information, to acquire a target wireless network corresponding to the current geographic location information;
wherein transmitting the control instruction to the automatic driving vehicle by using wireless channels corresponding to the plurality of wireless networks, comprises:
transmitting the control instruction to the automatic driving vehicle by using a wireless channel corresponding to the target wireless network.

3. The method according to claim 2 , further comprising:
acquiring a time when the remote control request is received by the server; and
determining a target wireless channel corresponding to the target wireless network according to the current geographic location information and the time,
wherein transmitting the control instruction to the automatic driving vehicle by using a wireless channel corresponding to the target wireless network, comprises:
transmitting the control instruction to the automatic driving vehicle by using the target wireless channel corresponding to the target wireless network.

4. The method according to claim 1 , further comprising:
acquiring current geographic location information of the automatic driving vehicle based on the information carried by the remote control request; and
wherein before transmitting the control instruction to the automatic driving vehicle by using wireless channels corresponding to the plurality of wireless networks, the method further comprises:
determining the wireless channel corresponding to each of the plurality of wireless networks based on the current geographic location information.

5. A remote control device for an automatic driving vehicle, comprising:
a processor; and
a memory, configured to store software modules executable by the processor, wherein the processor is configured to run a program corresponding to the software modules by reading the software modules stored in the memory, the software modules comprising:
a receiving module, configured to receive a remote control request transmitted by an automatic driving vehicle;
a first determining module, configured to determine a control instruction based on information carried by the remote control request;
a fifth acquiring module, configured to acquire current geographic location information of the automatic driving vehicle according to information carried by the remote control request;
a sixth acquiring module, configured to acquire a time when the remote control request is received by the remote control device that communicates with the automatic driving vehicle via wireless networks;
a fourth determining module, configured to determine a plurality of target wireless networks corresponding to the current geographic location information based on a pre-stored correspondence between geographic locations and wireless networks, and determine a plurality of target wireless channels corresponding to the plurality of target wireless networks based on the time; and
a transmitting module, configured to transmit the control instruction to the automatic driving vehicle by using the plurality of target wireless channels corresponding to the plurality of wireless networks.

6. The device according to claim 5 , wherein the software modules further comprise:
a first acquiring module, configured to acquire current geographic location information of the automatic driving vehicle according to information carried by the remote control request; and
a second acquiring module, configured to screen the plurality of the wireless networks according to the current geographic location information, to acquire a target wireless network corresponding to the current geographic location information;
wherein the transmitting module is configured to transmit the control instruction to the automatic driving vehicle by using the wireless channel corresponding to the target wireless network.

7. The device according to claim 6 , wherein the software modules further comprise:
a third acquiring module, configured to acquire a time when the remote control request is received by the remote control device; and
a second determining module, configured to determine a target wireless channel corresponding to the target wireless network according to the current geographic location information and the receiving time;
wherein the transmitting module is configured to transmit the control instruction to the automatic driving vehicle by using the target wireless channel corresponding to the target wireless network.

8. The device according to claim 5 , wherein the software modules further comprise:
a fourth acquiring module, configured to acquire current geographic location information of the automatic driving vehicle according to information carried by the remote control request; and
a third determining module, configured to determine the wireless channel corresponding to each of the plurality of wireless networks based on the current geographic location information, before the transmitting module transmits the control instruction to the automatic driving vehicle by using the wireless channels corresponding to the plurality of wireless networks.

9. A non-transitory computer readable storage medium having a computer program stored thereon, wherein when the computer program is executed by a processor, a remote control method is implemented, the computer program comprising:
program codes causing receiving a remote control request transmitted by an automatic driving vehicle;
program codes causing determining a control instruction based on information carried by the remote control request;
program codes causing acquiring current geographic location information of the automatic driving vehicle based on the information carried by the remote control request;
program codes causing acquiring a time when the remote control request is received by a server that communicates with the automatic driving vehicle via wireless networks;
program codes causing determining a plurality of target wireless networks corresponding to the current geographic location information based on a pre-stored correspondence between geographic locations and wireless networks, and determining a plurality of target wireless channels corresponding to the plurality of target wireless networks based on the time; and
program codes causing transmitting the control instruct
