Abstract

A navigation device (100) has a position detection section (7), an interface (4), a touch panel (62), and a computer (1). The computer (1) has timekeeper means for clocking a current time, estimated arrival time calculation means for calculating the estimated time of arrival at a destination by using the touch panel (62), mail creation instruction means for causing, through the interface, (4) a portable telephone (200) to create mail containing text that informs arrival at the calculated estimated time of arrival, and mail transmission instruction means for causing the portable telephone (200) to transmit the created mail. The estimated time of arrival is transmitted to the other party without operation of a portable telephone by a driver.

Claims

1. A navigation device comprising:

a display section;

an interface for communicating with a portable device;

a position detection section for detecting a current position;

a destination input section for inputting a destination; and

a computer having means for displaying a map image containing the current position detected by said position detection section on said display section;

said computer comprising;

timekeeper means for clocking a current time;

estimated arrival time calculation means for calculating an estimated time of arrival at a destination input by said destination input section based on the current time clocked by said timekeeper means;

mail creation instruction means for causing, through said interface, said portable device to create a mail containing text that informs arrival at the estimated time of arrival calculated by said estimated arrival time calculation means; and

mail transmission instruction means for causing said portable device to transmit the mail created in said portable device by said mail creation instruction means,

wherein said computer further comprises facility retrieval means for retrieving a facility in the surroundings nearest to the current position detected by said position detection means, and said mail creation instruction means causes, through said interface, said portable device to create the mail further containing text indicating that the facility retrieved by said facility retrieval means is at the current position.

2. A navigation device comprising:

a display section;

an interface for communicating with a portable device;

a position detection section for detecting a current position;

a destination input section for inputting a destination; and

a computer having means for displaying a map image containing the current position detected by said position detection section on said display section;

said computer comprising;

timekeeper means for clocking a current time;

estimated arrival time calculation means for calculating an estimated time of arrival at a destination input by said destination input section based on the current time clocked by said timekeeper means;

mail creation instruction means for causing, through said interface, said portable device to create a mail containing text that informs arrival at the estimated time of arrival calculated by said estimated arrival time calculation means; and

mail transmission instruction means for causing said portable device to transmit the mail created in said portable device by said mail creation instruction means,

wherein said computer comprises estimated arrival time recalculation means for recalculating the estimated time of arrival at the destination input by said destination input section based on the current time clocked by said timekeeper means, mail creation reinstruction means for causing, through said interface, said portable device to create the mail containing text that informs arrival at the estimated time of arrival calculated by said estimated arrival time recalculation means, and mail transmission reinstruction means for causing said portable device to transmit the mail created in said portable device by said mail creation reinstruction means,

wherein said mail transmission reinstruction means causes said portable device to transmit the mail after the passage of a predetermined time since said mail transmission instruction means caused said portable device to transmit the mail, and

wherein said computer further comprises second facility retrieval means for retrieving a facility in the surroundings nearest to the current position detected by said position detection means, and said mail creation reinstruction means causes, through said interface, said portable device to create the mail further containing text indicating that the facility retrieved by said second facility retrieval means is at the current position.
