Abstract
A system for an autonomous vehicle that receives driving environment information corresponding to a driving environment provided by another autonomous vehicle, and determines a navigation route based on a degree of reliability of the driving environment information provided by the another autonomous vehicle.
Claims17
A control device configured to support operations of an autonomous vehicle, the control device comprising:
- a transceiver:
- and
- control circuitry configured to:
- wirelessly receive from one or more other autonomous vehicles 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 one or more other autonomous vehicles,
- 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 deuee 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 sate drivin2 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.
