Classification: CPC G  B | IPC B  G

Claim 7:
8. A system for implementation in an autonomous vehicle, the control device comprising:
a transceiver; and
control circuitry configured to:
wirelessly receive from a server driving environment information corresponding to a driving environment detected by one or more other autonomous vehicles;
determine a degree of reliability of the driving environment information received from the server,
wherein the degree of reliability is determined based on time information indicating a time at which the driving environment information was acquired by the one or more other autonomous vehicles,
determine a navigation route based on the degree of reliability of the driving environment information,
control a driving system of the autonomous vehicle based on the degree of reliability of the driving environment information on the determined navigation route,
control the driving system in a predetermined autonomous driving mode under a condition that the degree of reliability of the driving environment information on the determined navigation route is higher than a first threshold value,
control the driving system in a predetermined safe driving mode under a condition that the degree of reliability of the driving environment information on the determined navigation route is lower than the first threshold value, and
control the driving system in a manual driving mode under a condition that the degree of reliability of the driving environment information on the determined navigation route is lower than a second threshold value which is lower than the first threshold value,
wherein:
in the manual driving mode, the driving system allows a driver to intervene in the operations of the autonomous vehicle,
a maximum speed of the autonomous vehicle in the predetermined safe driving mode is lower than a maximum speed of the autonomous vehicle in the predetermined autonomous driving, mode and
the first threshold and second threshold values are determined based on the driving environment information.
