A log transmission apparatus is a log transmission apparatus connected to a log collection apparatus via a communication network, and includes an application execution unit which outputs a log, an environment change management unit which generates an environment code as information indicating a change in a state of the log transmission apparatus, and a transmission unit which transmits the log and the environment code to the log collection apparatus, in which the environment change management unit generates the environment code indicating a change in the state during a period from a previous output to present output of the log by the application execution unit.

Log transmission apparatus and log collection system

A route information conversion system includes a route information transmission apparatus and a route information reception apparatus. The route information transmission apparatus includes: a route search unit that generates a search result of a route with reference to first map data; a position reference information generation unit that generates position reference information indicating a road corresponding to the search result; and a peripheral road information generation unit that generates peripheral road information indicating a road branching from the road corresponding to the search result. The route information reception apparatus includes: a route information restoration unit that restores route information on second map data from the position reference information; and a route match determination unit that determines whether the search result on the first map data and the route information on the second map data match each other with reference to the peripheral road information.

Route information conversion system, route information transmission apparatus, and route information reception apparatus

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.

When compressing an arrangement of fixed-length records in a columnar direction, a data compression device carries out data compression aligned with the performance of a data decompression device by computing a number of rows processed with one columnar compression from the performance on the decompression device side, such as the memory cache capacity of the decompression device or the capacity of a primary storage device which may be used by an application, and the size of one record. Thus, while improving compression ratios of large volumes of data, including an alignment of a plurality of fixed-length records, decompression performance is improved.

An information processing apparatus for operating a vehicle, when the vehicle is running, and an application is instructed through voice. An in-running operation acceptance/denial list is produced, i.e., a list of words meaning an operation to be inhibited from being executed during the time when the vehicle is running. A command acceptance/denial executing portion of the onboard apparatus determines if the command corresponding to the content, which a user speaks, can be operated or not, during the time when the vehicle is running, by referring this list and a title of the command operable through voices included in the application, and when the vehicle is running, an execution of that command is instructed to an application controller portion, if being determined operable, by referring to a running condition of the vehicle, and if being determined inoperable, the execution of that command is not instructed to the application controller portion.

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.

The technique is implemented by a vehicular device for performing dialogs with the driver. This device has: a communication portion for communicating with a server; an output portion for outputting speech information to the driver; an input portion for inputting information based on speech uttered by the driver; and a controller for controlling the communication portion, the output portion, and the input portion. When trigger information for starting a dialog process in the vehicular device or in the server is generated, the controller receives information indicative of the type of a first dialog forming a starting point of the dialog process and information indicative of the type of a second dialog forming an ending point of the dialog process from the server and carries out the dialog process based on the received information. The second dialog is different in type from the first dialog.
