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.

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.

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.

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. The variation information is extracted from the vehicle information so that the variation information is stored into the variation information memory.

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.

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.
