  • Publication number: 20240034320
    Abstract: A driving assistance apparatus for a vehicle includes an environment information acquisitor, a vehicle position estimator, a target route setter, and a controller. The environment information acquisitor acquires environment information in front of the vehicle. The vehicle position estimator estimates a position of the vehicle on a road. The target route setter sets a target route of the vehicle. The controller causes the vehicle to travel along the target route. The controller includes an intersection determiner, a right-left turn determiner, a route generator, and an intervention controller. The intersection determiner determines whether an intersection is in front of the vehicle based on the environment information. The right-left turn determiner determines whether the vehicle turns right or left at the intersection. The route generator generates correct and erroneous routes.

  • Patent number: 9515829
    Abstract: [Objective] When installing software into an in-vehicle terminal from a server, it is required to prevent the software from being installed into an unsuitable terminal, and to reduce time and efforts for data input and download, thereby improving the convenience of the user. [Solution] In an information distribution system, terminal identification information and a terminal unique key for an in-vehicle terminal are stored in a server as well as in itself. The in-vehicle terminal transmits the terminal identification information to the server for terminal authentication via a communication terminal after encrypting with the terminal unique key, and then the server transmits encrypted software to the communication terminal. The communication terminal transmits the encrypted software to the in-vehicle terminal, which in turn obtains a software unique key encrypted with the terminal unique key from the server and decrypts the encrypted software for installation using the software unique key.

  • Publication number: 20130267177
    Abstract: There is a demand for a technique that enable plural terminals devices to be easily paired with plural mobile terminals possessed by their respective users in a room where the terminal devices that can be shared among the users are installed. Each terminal device searches for mobile terminals present within the wireless range. If the plural mobile terminals are present within a searchable area, the search result indicates plural mobile terminals, making it difficult to determine with what mobile terminal should the terminal device be paired. The current states of various sensors of the mobile terminals are included in information indicating the names of the mobile terminals and are searched by the terminal device. Under circumstances where the plural terminal devices and the plural mobile terminals exist within short distances, the mobile terminal unit to be paired with the terminal device can be found with ease.

  • Patent number: 8341703
    Abstract: In remotely coupling one terminal apparatus to a server apparatus, if an authentication processing of a user of one terminal apparatus has been already completed, the user can switch one terminal apparatus to another without an additional authentication processing. Authenticated information indicating that the authentication of the user has already been successfully completed is transferred to another terminal apparatus by coordinating the authenticated information between more than one terminal apparatuses. Another terminal apparatus receives a service from the server apparatus using the authenticated information. Upon coordinating the authenticated information among more than one terminal apparatuses, another terminal apparatus to receive the authenticated information may be authenticated. A storage medium which conducts the authentication may be coupled to a terminal apparatus to be authenticated.

  • Publication number: 20100261452
    Abstract: A coupling authentication of a mobile phone terminal is performed between the mobile phone terminal and an authentication server. Both the mobile phone terminal and an authentication server store therein coupling authentication information. In performing an authentication at a service device, the mobile phone terminal generates service authentication information using coupling authentication information and transmits the generated service authentication information to the authentication server. The authentication server performs the authentication using the coupling authentication information and the service authentication information and transmits a result of a service authentication to the service device. The service device determines whether or not the service authentication has been successfully completed, based on the service authentication result.
