A network of a new configuration is flexibly constructed while maintaining a stable operation in the network. A management device includes: a detection unit that detects addition of a function unit to a network including one or a plurality of on-vehicle function units; an acquisition unit that acquires function unit information of a new function unit that is the function unit the addition of which has been detected by the detection unit and function unit information of each on-vehicle function unit, each piece of function unit information including information regarding network configuration of a layer lower than an application layer; and a generation unit that, based on the pieces of function unit information acquired by the acquisition unit, generates configuration information of a new network that is the network further including the new function unit.

Management device, vehicle communication system, vehicle, vehicle communication management method, and vehicle communication management program

A vehicle-mounted device includes a data collecting device that collects sensor data from a vehicle sensor, a data transmitting device that transmits the sensor data to a server, a data receiving device that receives data about an outside-vehicle status, and an inside-vehicle/outside-vehicle cooperation device that, in response to receipt of the data about the outside-vehicle status, cooperates with a device outside the vehicle and controls an operation inside the vehicle. The server includes a map creating device that maintains a traffic status overview map on the basis of received sensor data, a vehicle selecting device that selects a vehicle capable of transmitting optimum sensor data for maintaining the traffic status overview map in view of a line status among vehicle-mounted devices present within a specific area, and a transmission permission/prohibition signal transmitting device that transmits an instruction of permitting transmission of sensor data to the vehicle.

Traffic assistance system, server, and vehicle-mounted device

The present disclosure relates to a route search system including a route search apparatus that communicates with a mobile terminal. The route search apparatus includes: a communication unit that receives, from the mobile terminal, a search request including identification information of a user, and transmits a search result corresponding to the search request to the mobile terminal of the user; and a control unit that executes a search process for a multimodal route that includes at least one of a pedestrian route, a non-public route, and a public route, in accordance with the received search request, and causes the communication unit to transmit the multimodal route as a search result. The control unit causes a passage schedule of the at least one route, and identification information, of traveling means used for traveling along the at least one route, which is associated with the identification information of the user, to be included in a data content of the multimodal route.

Route search system, route search apparatus, route search method, and computer program

An information providing system according to one mode of the present disclosure includes: one or a plurality of mobile terminals each configured to transmit first information based on own sensor information to a server; one or a plurality of fixed terminals each configured to transmit second information based on own sensor information to the server; and the server configured to generate third information on the basis of the first information and the second information that have been received by the server, and configured to transmit the generated third information to at least the mobile terminal.

Information providing system, server, mobile terminal, and computer program

An on-vehicle communication system mounted on a vehicle is provided with a master function unit and a plurality of slave function units. The plurality of slave function units are able to transmit uplink communication signals to the master function unit via at least a common optical fiber.

On-vehicle communication system

A switch device is a switch device that relays data in an in-vehicle network and including a plurality of first communication ports which are connectable to a plurality of functional units in a vehicle, and includes a plurality of first communication circuits disposed corresponding to the first communication ports and capable of communicating with the functional units via the corresponding first communication ports, one or more second communication circuits different from the plurality of first communication circuits, a switching unit capable of switching a connection destination of each of the first communication ports between the corresponding first communication circuit and the second communication circuit, and a control unit that controls the switching unit such that a connection destination of a target port which is the first communication port serving as a target is switched to the second communication circuit when a predetermined condition is satisfied.

Switch device, communication control method, and recording medium

A wireless communication system according to one mode of the present invention includes: an information providing terminal being a communication terminal belonging to a first node below, the information providing terminal configured to transmit, to another station, first provision information that includes source data usable for driving support control; a base station belonging to a second node below and configured to transmit, to another station, second provision information based on the source data; a server belonging to a third node below and configured to transmit, to another station, third provision information based on the source data; an information acquiring terminal being a communication terminal belonging to the first node below, the information acquiring terminal being mounted to a target vehicle to which the first to third provision information is to be provided; and a determination unit configured to determine whether or not adoption of the first to third provision information is allowed, on the basis of a position of the target vehicle and a position associated with the source data.

Wireless communication system, information acquiring terminal, computer program, method for determining whether to adopt provided information

An in-vehicle communication system includes first and second switch devices that perform a relay process of relaying data in an in-vehicle network, the first switch device includes a switch unit and a processing unit that performs the relay process via the switch unit, the switch unit transmits target data to the second switch device instead of outputting the target data to the processing unit when an abnormality in the processing unit is detected, the target data being data which is received from a device other than the second switch device and is to undergo the relay process performed by the processing unit, and the second switch device performs a proxy process of relaying the target data received from the switch unit instead of the processing unit.
