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.

Calculation apparatus and arithmetic method

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.

The present invention performs route guidance that excludes a difficult-to-travel section appropriately and provides an alternative route with favorable route quality. A navigation deviceincludes an arithmetic devicethat, when a route including a difficult-to-travel section is found, identifies the route as a candidate route while adding a predetermined penalty cost to the cost of the route, identifies an alternative route obtained by coupling a first partial route from a constituent node in the difficult-to-travel section of the found route to a destination with a second partial route from the departure point of the found route to a node having already been searched for, identifies the alternative route as a candidate route after adding a coupling cost for reaching from the already-searched node to the certain constituent node in the difficult-to-travel section to costs of the first and second partial routes, selects one of the candidate route with the penalty cost and the candidate route with the coupling cost with the smaller cost as a guidance route.

Navigation device, route search server, and route search method

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.
