Abstract:
A delay system which has a communications device connected to a communications network and a relay device which is connected between the communications network ad an external device. The relay device is configured to divide data received from the external device into a plurality of data fragments each containing divided data, and send a sequence of messages, the messages corresponding to the respective divided data and dummy messages being included in the sequence of messages according to a communications rule. The communications device is configured to reconstitute the data from the external device on the basis of the message group from the relay device according to the communications rule.

Abstract:
A driving support apparatus includes: a scheduled change detection section that detects a lane change schedule of a target vehicle; a competition detection section that detects a competing vehicle that is making lane change to the same lane as that to which the target vehicle is making lane change, while competing with the target vehicle, when the scheduled change detection section detects the lane change schedule; and a timing setting section that sets timing of lane change of the target vehicle depending on the competing vehicle when the competition detection section detects the competing vehicle.
Abstract:
A communications relay apparatus for relaying communications between an electronic control unit (ECU) connected to the apparatus via an in-vehicle local area network (LAN) and an external device connected to the apparatus via a communication path different from the in-vehicle LAN. In the apparatus, a data transfer unit forwards relay data received from the ECU to the communication path and forwards relay data received from the external device to the in-vehicle LAN. But the data transfer unit is inhibited from forwarding reprogramming data for reprogramming the ECU received from the external device to the in-vehicle LAN. An authentication unit authenticates a vehicle user, and when the vehicle user is successfully authenticated, then permits the data transfer unit to forward the reprogramming data to the in-vehicle LAN.
