Embodiment Construction

[0020] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0021] figure 1 It is a functional block diagram of the navigation device of the present invention. Reference numeral 101 is the vehicle position detecting unit mounted on the navigation device, which detects the current position of the vehicle (the current position composed of latitude and longitude) and its current driving direction, and is a GPS (Global Positioning System) which utilizes artificial satellites to measure the current position. System) receiver, a geomagnetic sensor that obtains the vehicle orientation by detecting geomagnetism, a gyro sensor, and other sensors. Reference numeral 102 is a map data storage unit, which is composed of a hard disk or a semiconductor memory, and stores map data and road data divided into appropriate latitude and longitude according to different scales. This map data includes positional information of restricted areas such ...

Abstract

The invention aims to provide a navigation unit and a parking warning method thereof, being capable of preventing a driver from wrongly parking a vehicle which is not in an emergency parking state in an emergency parking zone. The navigation unit of the invention comprises a map data storage part, a vehicle location detection part, a parking detection part, a parking location judgment part, a vehicle state judgment part and an alarming part, wherein the map data storage part is used for storing map data; the vehicle location detection part is used for detecting the location of the vehicle; the parking detection part is used for detecting whether the vehicle is in a parking state or not; the parking location judgment part is used for judging whether the vehicle location detected by the vehicle location detection part is located in the emergency parking zone containing the map data when the vehicle location detection part judges the vehicle is in a parking state; the vehicle state judgment is used for judging whether the vehicle is in an emergency parking state; and the alarming part is used for alarming an user when the parking location judgment part judges that the vehicle is parked in the emergency parking zone and the vehicle state judgment part judges that the vehicle is not in the emergency parking zone.

Description

technical field [0001] The present invention relates to a navigation device capable of preventing a driver from parking by mistake in a no-parking area and a parking warning method thereof, in particular to a navigation device and a parking warning method capable of informing a user whether parking in an emergency parking area is possible according to the state of the vehicle method. Background technique [0002] The traffic laws and regulations of various countries stipulate parking restricted areas such as no-parking areas and emergency parking areas. A situation where parking by mistake occurs in a no-parking area, etc., thereby violating traffic laws. In order to prevent the driver from violating traffic regulations unconsciously, the navigation system described in the following patent document 1 judges whether the parking position of the vehicle is in a prohibited parking area stipulated in the traffic regulations when judging that the vehicle is in a parked state. Th...
