Description

  The present invention relates to a navigation apparatus and relates to an information transmission / reception apparatus that transmits information such as a current position and a destination arrival scheduled time to a mobile phone or a wireless communication device.

  Conventionally, the location information is received from the waiter at the destination, the route from the current position of the vehicle to the destination is searched, the expected arrival time at the destination or the remaining distance to the destination is determined by the mobile phone or wireless communication device of the waiter It is known that the waiting person can regularly know the current position of the vehicle to be picked up and the estimated arrival time by periodically transmitting to (see Patent Document 1).

  However, the current position of the vehicle and the estimated arrival time are regularly transmitted to and received from the waiting person regardless of the actual driving situation, and the waiting person has to confirm all information. There is a problem that the communication cost increases as well. As a method for solving this problem, an apparatus having means for transmitting a message having an appropriate content to a waiting person at an appropriate timing has been invented. Specifically, the navigation side obtains the waiting time, calculates the estimated arrival time to the meeting place, calculates the time difference between the waiting time and the estimated arrival time, and determines the message transmission timing according to this value. It controlled (refer patent document 2).
