Abstract: A vehicular data communication system includes an authentication device for authenticating an external tool connected to a bus, an authentication control device for determining whether an external tool is authenticated by the authentication device and for setting an authenticated state to permit a data communication between the external tool and an access target ECU on the bus upon determining that the external tool is authenticated by the authentication device, and an authentication maintain device for maintaining the authenticated state within a predetermined period after the authenticated state is set by the authentication control device.

Abstract: A pedestrian notification apparatus, which is configured to be used in a vehicle, includes an ambient object detector, a notification target detector and a notifier. The ambient object detector is configured to detect ambient objects present around the vehicle. The notification target detector is configured to detect a notification target pedestrian based on the detection results of the ambient object detector. The notifier is configured to notify the notification target pedestrian that the notification target pedestrian has been detected by the notification target detector.

Abstract: A display control device for a remote control device is disclosed. The display control device is configured to have connection with a display device and a remote control device spaced apart from each other. The display device is configured to display an operation screen having multiple icons for accepting an operation directed to a control target apparatus. When display is switched from a first operation screen to a second operation screen having a different icon arrangement, the display control means shifts an icon selection state from one icon selected on the first operation screen to an initial selection icon pre-set on the second operation screen and causes the display device to display a visual effect indicative of a direction from position of the selected one icon to position of the initial selection icon.

Abstract: A vehicle communication system includes at least one device control apparatuses. One device control apparatus has an electronic controller. The vehicle communication system includes an information memory apparatus that is another vehicle apparatus different from the first device control apparatuses. The electronic controller of the device control apparatus stores a variation information memory, a process execution portion and a vehicle information obtaining portion. The information memory apparatus stores a vehicle information memory and a vehicle information providing portion. The process execution portion switches and executes a content of the device control process based on the variation information. The vehicle information is related to specifications of a vehicle on which the vehicle communication system is mounted, and it is obtained from the information memory apparatus.

Abstract: A driving support apparatus includes: a driving support controller for starting to execute a driving support control when a support start condition is met; a current position detector; and a driving direction determination unit for successively determining whether there is a possibility of a vehicle turning at an intersection in a direction, to which a blinker turns. The driving support controller sets an enforcement notification state when the driving direction determination unit determines the possibility after the driving support controller starts to execute the driving support control. The driving support control provides to notify information in the enforcement notification state even when the blinker turns off, and ends the enforcement notification state when the driving direction determination unit determines no possibility.

Abstract: A vehicle information storing apparatus stores a camera image, acceleration or the like, which a user selected from vehicle information stored in a RAM, and an intersection, a curve or the like of navigation information into a flash memory under a predetermined condition. The predetermined condition may include that a user performed a vehicle information selection operation for selecting the camera image or acceleration, the user performed a specific item selection operation for setting the intersection or curve, a vehicle enters within a predetermined distance range from a set location and navigation information received from a navigation device satisfies a predetermined condition.

Abstract: In an electronic toll collection system, card data of a payment card is stored in an on-board unit mounted in a vehicle. Toll data necessary for a toll collection transaction including the card data is copied from the on-board unit to a cellular phone. A user passes the cellular phone to a tollgate attendant, and the toll data is moved to a toll collection unit installed at a tollgate. The toll collection unit calculates a toll fee based on the toll data and generates a delete command and road use data. When the tollgate attendant passes a portable terminal of the toll collection unit to the user, the delete command and the road use data are copied to the on-board unit. The toll data is deleted from the on-board unit by the delete command, and the road use data is reported to the user.

Abstract: A display control device for a remote control device is disclosed. The display control device is connected with a display device for displaying an operation screen having multiple icons and a remote control device spaced apart form the display device. The display control device performs display control in the following way. The display control device displays an identification display mark in association with one icon in a selection state. When an instruction of an operation direction is inputted, the display control device displays a visual presentation indicative of the operation direction on the operation screen by making a change in display manner of the identification display mark, with the identification display mark being displayed in association with the one icon in the selection state.

Abstract: The in-vehicle apparatus card information stored in a storage section is set to an inactive state and is prevented from being read from the storage section when an ignition switch changes from “on” to “off” or when a user performs an operation signifying a change from an active state to the inactive state. Accordingly, the in-vehicle apparatus card information is disabled by an explicit user operation or a normal operation performed when the user gets out of a vehicle. It is possible to prevent the unauthorized use of the in-vehicle apparatus card information when the user does not get in the vehicle.

Abstract: A wireless communication system provides a decryption module for decrypting card information on a roadside unit for information registration and a roadside unit for toll collection instead of providing the decryption module on a vehicle unit. In this manner, the wireless communication system can accommodate an IC card that uses a new encryption method more easily relative to a conventional wireless communication system, because the roadside units are smaller in number in comparison to the vehicle units at the time of system operation with greater allowance for demand for space efficiency and cost reduction.
