Abstract: A calculation apparatus includes a control unit configured to calculate a necessary distance that is necessary for a vehicle to perform lane change from a first travel lane to a second travel lane by combining a first distance that the vehicle travels while the vehicle waits to start the lane change, a second distance that the vehicle travels while a speed of the vehicle is adjusted, and a third distance that the vehicle travels while executing the lane change.

Abstract: A user is notified of a recommendation lane as appropriate. A navigation system includes one or more processors, and one or more storage devices storing programs to be executed by the one or more processors. The one or more processors decide a lane change plan creation zone including a main lane group including a plurality of main lanes that is parallel to each other in a route between a place of departure and a destination, and a recommendation degree of each of a plurality of lane links included in the main lane group. The one or more processors generate a lane change plan on the basis of the lane change plan creation zone and the recommendation degree.

Abstract: Updating software in consideration of a preceding software update state is performed in an electronic control unit of a vehicle. A server communicates with a software update apparatus that updates software of an in-vehicle control device. The server includes a software update sequence control unit that manages a software update to the in-vehicle control device. When a subsequent second software update is registered in the server during an application of a preceding first software update to the in-vehicle control device, the software update sequence control unit determines whether to interrupt the application of the first software update and start an application of the second software update to the in-vehicle control device based on information relating to the application of the first software update, information relating to the application of the second software update, and an update processing state of the first software update to the in-vehicle control device.

Abstract: A route information transmission method is a route information transmission method including: calculating the driving route of a vehicle from an origin to a destination; extracting combinations of latitudes and longitudes from the calculated driving route; and transmitting the extracted combinations of latitudes and longitudes to the vehicle.

Abstract: The present invention performs route guidance that excludes a difficult-to-travel section appropriately and provides an alternative route with favorable route quality.

Abstract: A program manager operating on a smartphone transmits information of an onboard apparatus and a program ID list of the smartphone to the server. The server determines the possibility of an expansion of one or more programs, and the difference between charge/free provisioning of the program. If a function expansion condition of the program is met, the server transmits it to the smartphone. The program manager of the smartphone inquires as to possibility/impossibility of expansion, and a password (when there is a charge), and transmits the authentication information and the password (if there is a charge), which are produced from an onboard apparatus ID, a random number, secret data unique to the onboard apparatus, etc., to the server. The server transmits function expansion data to the smartphone, when succeeding the authentication, and the program management portion executes the function expansion of the program.

Abstract: When a browser is displayed on an in-vehicle information processing device, an appropriate display screen is displayed according to a driving state of a vehicle. While moving, web content is processed based on a restriction rule so that a moving image or the like is not reproduced. Further, when an operation of switching a display from another application other than the browser to the browser or an operation of switching a display to another web content on the browser is input to an in-vehicle terminal, the driving state of the vehicle is determined. In a state in which the vehicle stops, web content is displayed without change, and in a state in which the vehicle is moving, when processed web content is being stored, the processed web content is read and displayed, and when processed web content is not being stored, web content is read, processed based on the restriction rule, and then displayed.
