A system for instructing an Autonomous Vehicle (AV) to perform a minimal risk condition maneuver comprises a fleet of AVs and an oversight server. The oversight server receives macro information that applies to a plurality of AVs from the fleet. The oversight server generates a batch command based on the macro information. The batch command is associated with one or more conditions. The oversight server determines whether each AV meets the one or more conditions. If the oversight server determines that the AV meets the one or more conditions, the oversight server sends the batch command to the AV. The batch command includes instructions to perform a minimal risk condition maneuver.

A communication control device (5) includes: a vehicle information acquiring unit (41) to acquire vehicle information including communication performance information indicating performance of wireless communication in each of a plurality of vehicles (V); a data assignment unit (42) to assign individual pieces of data (D) included in a data group (DG) collected by a vehicle group (VG) to respective selected vehicles (V) among the plurality of vehicles (V) on the basis of the performance of the wireless communication; a data distribution unit (43) to execute control to distribute a piece of data (D) included in the data group (DG) to a corresponding one of the plurality of vehicles (V) by the wireless communication on the basis of a result of the assignment by the data assignment unit (42); and a transmission control unit (44) to execute control to transmit one of the pieces of data (D) which is assigned to a representative vehicle to a server (2) by the wireless communication.

A method performed in an Internet of Vehicles data transmission system is provided in the present disclosure, where the Internet of Vehicles data transmission system includes a plurality of clusters and at least one road-side unit connected to the Internet, each cluster includes at least one on-board unit, and the at least one on-board unit includes a cluster head on-board unit, and the method includes: transmitting data in the on-board unit to one of the at least one road-side unit, via the cluster head on-board unit of the cluster where the on-board unit belongs. An on-board unit and an Internet of Vehicles data transmission system are further provided.

A method of controlling movement of multi-vehicle includes acquiring a constraint condition under which vehicles move and a calculation cycle for calculating movement routes of the vehicles; acquiring a position of each vehicle; specifying a target position for each vehicle; calculating, based on the position of each vehicle, the target position, and the constraint condition, a movement route for prediction steps of each vehicle; determining, based on the movement routes of the vehicles, a driving condition of each vehicle from a current time to a unit time; and controlling movement of each vehicle. Calculating the movement route including performing optimization calculation based on an evaluation function, evaluation of which becomes higher as a deviation between the vehicle and the target position for each prediction step becomes smaller, and the constraint condition, to calculate the movement route.

A driving supporting apparatus comprises a notification device that performs a notification to a driver of a host vehicle; and a control unit capable of causing the notification device to perform an approaching notification to notify the driver that a following vehicle present behind the host vehicle has approached the host vehicle, when the following vehicle satisfies a predetermined approaching condition. The control unit is configured to cause the notification device to perform the approaching notification, when the following vehicle satisfies the approaching condition in a case where an adjacent lane is present, if a permission condition depending on presence or absence of an adjacent vehicle traveling in the adjacent lane is satisfied. The permission condition used when the adjacent vehicle is present has been set to a condition that is harder to be satisfied than a condition set as the permission condition used when the adjacent vehicle is not present.

Systems and methods use cameras to provide autonomous navigation features. In one implementation, a method for navigating a user vehicle may include acquiring, using at least one image capture device, a plurality of images of an area in a vicinity of the user vehicle; determining from the plurality of images a first lane constraint on a first side of the user vehicle and a second lane constraint on a second side of the user vehicle opposite to the first side of the user vehicle; enabling the user vehicle to pass a target vehicle if the target vehicle is determined to be in a lane different from the lane in which the user vehicle is traveling; and causing the user vehicle to abort the pass before completion of the pass, if the target vehicle is determined to be entering the lane in which the user vehicle is traveling.

Logic may implement protocols and procedures for vehicle-to-vehicle communications for platooning. Logic may implement a communications topology to distinguish time-critical communications from non-time-critical communications. Logic may sign time-critical communications with a message authentication code (MAC) algorithm with a hash function such as Keccak MAC or a Cipher-based MAC. Logic may generate a MAC based on pairwise, symmetric keys to sign the time-critical communications. Logic may sign non-time-critical communications with a digital signature. Logic may encrypt non-time-critical communications. Logic may append a certificate to non-time-critical communications. Logic may append a header to messages to create data packets and may include a packet type to identify time-critical communications. Logic may decode and verify the time-critical messages with a pairwise symmetric key. And logic may prioritize time-critical communications to meet a specified latency.

A method, a computer program, an apparatus, a transportation vehicle, and a network component for controlling a maneuver within a platoon of transportation vehicles. The method for controlling a maneuver within a platoon of transportation vehicles includes receiving information related to a maneuver for the platoon; determining information on a fuel efficiency of the maneuver based on fuel consumptions for maneuvering from an initial state to a maneuver target state, keeping the maneuver target state, and reverting from the maneuver target state to the initial state; and deciding whether to perform the maneuver based on the information on the fuel efficiency.

A method and system for providing a companion autonomous vehicle are described. In one embodiment, a method includes linking a companion autonomous vehicle to at least one vehicle, device, or user. The companion autonomous vehicle is tethered to the at least one vehicle, device, or user such that the companion autonomous vehicle is configured to stay within a predetermined range of the at least one vehicle, device, or user. The method further includes operating the companion autonomous vehicle to travel along with the tethered at least one vehicle, device, or user within the predetermined range.

A vehicle platooning method includes an information collection operation in which a leader vehicle in a platooning convoy platooning receives information from other vehicles in the platooning convoy and checks the other vehicles; and a determination operation in which, when a request for joining the platooning convoy is received from an external vehicle not participating in the platooning convoy, the leader vehicle receives information about the external vehicle and determines whether to approve the request for joining the platooning convoy. The external vehicle is notified of a result of and a reason for the determination.
