Vehicle manufacturing system, vehicle manufacturing method, and non-transitory computer readable medium
A vehicle manufacturing system includes: a first information acquisition unit configured to acquire first information indicating positions and attitudes of a plurality of vehicles from outside of the plurality of vehicles, the plurality of vehicles being manufactured step by step while they are continuously moving; a second information acquisition unit configured to acquire second information, provided in at least one of the vehicles, the second information indicating a position and an attitude of a vehicle in front of or behind the vehicle; and an abnormality occurrence detection unit configured to switch control of the plurality of vehicles or notify someone or something outside the plurality of vehicles when a difference between the positions and attitudes of the plurality of vehicles acquired from the first information and the positions and attitudes of the plurality of vehicles acquired from the second information is larger than a predetermined value.
1 . A vehicle manufacturing system in which a plurality of vehicles is manufactured step by step while they are continuously moving comprising:
a first information acquisition external sensor configured to acquire first information indicating positions and attitudes of each of the plurality of vehicles from outside of the plurality of vehicles;
a second information acquisition internal sensor, provided in at least one of the plurality of vehicles, configured to acquire second information indicating a position and an attitude of a vehicle of the plurality of the vehicles in front of or behind each respective one of the at least one of the plurality of the vehicles; and
an abnormality occurrence detection unit configured to switch control of the plurality of vehicles or notify someone or something outside the plurality of vehicles when a difference between a position and attitude of a given vehicle of the plurality of vehicles acquired from the first information and a position and attitude of the given vehicle of the plurality of the vehicles acquired from the second information is larger than a predetermined value.
2 . The vehicle manufacturing system according to claim 1 , wherein:
the first information is an image,
the second information is an image,
the first information acquisition external sensor is a photographing apparatus, a LIDAR, a radar, or an ultrasonic sensor, and
the second information acquisition internal sensor is a photographing apparatus, a LiDAR, a radar, or an ultrasonic sensor.
3 . The vehicle manufacturing system according to claim 1 , wherein the switching of control of the plurality of vehicles is to stop or decelerate the plurality of vehicles.
4 . The vehicle manufacturing system according to claim 1 , wherein the notification to the outside is to notify a manager, an operator, or a production management system of an abnormality.
5 . A method for manufacturing vehicles in which a plurality of vehicles is manufactured step by step while the plurality of vehicles is continuously moving, comprising:
acquiring first information indicating positions and attitudes of each of the plurality of vehicles by using a first information acquisition external sensor provided outside the plurality of vehicles;
acquiring, by using a second information acquisition internal sensor provided in at least one of the plurality of the vehicles, second information indicating a position and an attitude of a vehicle of the plurality of the vehicles in front of or behind each respective one of the at least one of the plurality of the vehicles; and
switching control of the plurality of vehicles or notifying someone or something outside the plurality of vehicles when a difference between a position and attitude of a given vehicle of the plurality of vehicles acquired from the first information acquisition external sensor and a position and attitude of the given vehicle of the plurality of the vehicles acquired from the second information acquisition internal sensor is larger than a predetermined value.
6 . The method according to claim 5 , wherein the predetermined value is changed according to a specific section.
7 . The method according to claim 6 , wherein the specific section is a section in which a vehicle of the plurality of the vehicles makes a U-turn, a section having a turning curvature, or a slope.
