Navigation system, portable terminal device, and in-vehicle device
First Claim
1. A navigation system for providing route information including an actual location of a vehicle, the navigation system comprising an in-vehicle device mounted on the vehicle and a portable terminal device carried by a passenger,the in-vehicle device including:
- a vehicle-information providing unit that collects and provides position information and movement information of the vehicle to the portable terminal device,the portable terminal device including;
a setting unit that receives, from the passenger, a setting related to a scale size of map information to be acquired from a map center device, wherein the setting related to the scale size of the map information, inputted by the passenger, is a plurality of correspondences between scale sizes and speed ranges;
a scale-size determining unit that determines a scale size requested to the map center device based on the setting received by the setting unit and the movement information sent from the vehicle-information providing unit of the in-vehicle device;
a map-information acquiring unit that acquires map information whose scale size is determined by the scale-size determining unit from the map center device;
an actual-location calculating unit that calculates the actual location of the vehicle based on the position information and the movement information sent from the vehicle-information providing unit of the in-vehicle device; and
an image-data generating unit that generates the image data in which the actual location calculated by the actual-location calculating unit is superposed on the map information acquired by the map-information acquiring unit, and sends the generated image data to the in-vehicle device,the in-vehicle device further including a display unit that displays the image data sent from the portable terminal device.

Abstract
A navigation system is configured such that: an in-vehicle device collects and provides position information and movement information of a vehicle to a portable terminal device, and displays image data sent from the portable terminal device. The portable terminal device acquires map information from a map center device based on the position information and the movement information sent from the in-vehicle device, calculates an actual location of the vehicle based on the position information and the movement information sent from the in-vehicle device, and generates image data in which the calculated actual location is superposed on the acquired map information.

9. A portable terminal device for providing route information including actual location of a vehicle in cooperation with an in-vehicle device mounted on the vehicle to collect position information and movement information of the vehicle, the portable terminal device comprising:
-
a non-transitory storage device that stores information therein; and a controller coupled to the storage device, wherein the controller executes a process comprising; receiving, from a passenger of the vehicle, a setting related to a scale size of map information to be acquired from a map center device wherein the setting related to the scale size of the map information, inputted by the passenger, is a plurality of correspondences between scale sizes and speed ranges; determining a scale size requested to the map center device based on the received setting and the movement information of the vehicle collected by the in-vehicle device; acquiring map information whose scale size is determined at the determining operation from the map center device; calculating an actual location of the vehicle based on the position information and the movement information collected by the in-vehicle device; generating image data by superposing the actual location calculated in the calculating operation based on the map information acquired in the acquiring operation; and providing the generated image data to the in-vehicle device.
