Vehicle navigation system
First Claim
1. A vehicle navigation apparatus for use in a vehicle comprising:
- an operation unit that accepts a user operation by a user;
a control unit that controls data communication;
a wireless communication unit that wirelessly exchanges data with a service center through a communication line, wherein, when the user operation from the user on the operation unit is accepted only on a condition that the vehicle is in a stopping condition and the user operation is accompanied by the data communication between the wireless communication unit and the service center through the communication line, the data communication according to the user operation is either performed at a time of the user operation under a circumstance that the communication line is in a connected condition between the wireless communication unit and the service center, or performed at a time after connecting the communication line between the wireless communication unit and the service center under a circumstance that the communication line is disconnected between the wireless communication unit and the service center; and
a speed sensor that detects a speed of the vehicle,wherein the control unit connects the communication line between the wireless communication unit and the service center when a first condition and a second condition are fulfilled,the first condition is that the speed of the vehicle detected by the speed sensor is smaller than a predetermined value, andthe second condition is that the communication line between the wireless communication unit and the service center is being disconnected.

Abstract
A vehicle navigation system is configured to connect a communication line from a wireless communication unit to a service center when a vehicle is traveling at a speed slower than a predetermined value and the communication line to the service center is not connected. By setting the predetermined value of the speed to a certain range in which the vehicle is highly probable to stop (e.g., a speed of a few kilometers per hour), the communication unit of the vehicle navigation system starts a connection operation of the communication line to the service center before the vehicle comes to a full stop, thereby enabling an establishment of connection of the communication line between the communication unit and the service center prior to the full stop of the vehicle.
