Problems solved by technology

[0009] However, when it is desired to realize a navigation system by cooperating with an in-vehicle device mounted on a vehicle and a portable terminal device carried by a passenger, if there are overlapping functions in each device, there is a possibility that it will eventually become an expensive system. question

Embodiment

[0029] figure 1 It is a figure which shows the feature of the navigation system of this Example. As shown in the figure, the navigation system 1 of the present embodiment is composed of a GPS (Global Positioning System) antenna (including a GPS positioning system) or a driving state acquisition sensor (for example, a vehicle speed sensor, a rudder angle sensor, a yaw rate ) Sensors such as sensors) are connected to the vehicle-mounted device, and the mobile terminal device 20 constitutes. In addition, the mobile terminal device 20 acquires a map for navigation from an external map center (a center operated by a communication provider, etc.).

[0030] as it should figure 1 As shown, when performing GPS-based positioning, it is necessary to receive radio waves from multiple GPS satellites to calculate the position of the receiving point. However, when using a mobile phone with a GPS function in a car, it is difficult to keep the mobile phone in a good reception state becaus...

Abstract

A navigation device is constructed such that a vehicle-mounted device collects position information and movement information on a vehicle, provides a portable terminal device with the collected information, and displays image data received from the portable terminal device, and that the portable terminal device acquires map information from a map center device based on the position information and movement information received from the vehicle-mounted device, calculates the current position of the vehicle based on the position information and movement information received from the vehicle-mounted device, and creates image data formed by overlaying the calculated current position on the acquired map information.

Description

technical field [0001] The present invention relates to a navigation system, a portable terminal device, and a vehicle-mounted device that provide route information including the current position of the vehicle by using a vehicle-mounted device mounted on a vehicle and a portable terminal device carried by a passenger, and particularly relates to a system that suppresses A navigation system, a portable terminal device, and an in-vehicle device that can perform accurate navigation while duplicating resources. Background technique [0002] There is known a car navigation system that calculates the current position by using GPS (Global Positioning System), gyroscope, vehicle speed sensor, etc. to synthesize the position of the vehicle and map information about surrounding roads or buildings, and then display it on a display. [0003] In addition, as the performance of portable terminal devices such as mobile phones and PDAs (Personal Digital Assistant) has improved, navigation ...
