Abstract
Current position of a vehicle and current time are acquired. A user recognizing unit recognizes a user. A pattern recognizing unit detects location of a portable device and movement thereof. Operation state of an engine is acquired from an engine control mechanism. Based on the information, processes are performed such as switching communication stand-by mode of the portable device to active stand-by mode, notifying the portable device of a transition of an on-board terminal to automatic locking mode, preventing needless unlocking and locking of doors, and setting warning mode of the portable device.
