Abstract

(57) [Summary] This bulletin contains application data before electronic filing, so abstract data is not recorded.

Description

[Detailed description of the invention] The present invention relates to a drive guide device for one drive.

[Conventional technology]

Fig. 2 is a block diagram showing a conventional drive guide device. (8) is a manual input device for inputting the starting point, direction of travel, map reduction ratio, etc. for the map attached to the vehicle; (4) is an axle-mounted tachometer for calculating mileage, and (5) is a central processing unit (CPTR) that calculates the position based on each input and outputs the current position to the display (1). .

The operation related to the above configuration will be explained. Initial conditions such as the current position, destination, distance, etc. on the map attached to the display (1), as well as the starting direction are input using the manual input device (2). In addition, basic data for providing information to the driver, such as the relationship between the axle-mounted tachometer (4), travel distance, and travel speed, is input using the manual input device (2). When the car starts running, the CPU (5) uses the initial conditions and basic data input through the manual input device 1 to
Sensing data from the direction detector (3) and the axle-mounted tachometer (4) is input and processed, and the map-attached display (1) displays the current position, direction of travel, etc., as well as elapsed time, distance traveled, etc.
[Problems to be Solved by the Invention] However, conventional drive guidance devices do not store maps as described above, and therefore Running progress.

Because information such as the planned driving route cannot be stored on the map,
There was a problem in that it was not possible to accurately indicate the return route, the route for re-travelling, and the planned route.

This invention was made to solve the above-mentioned problems, and it is possible to store a map, add a driving route or a planned driving route to the map, and recall the information as needed. To provide a drive guidance device capable of providing information on a stored map to a driver.

[Means for solving problems]

A drive guide device according to the present invention includes a magnetic memory device,
New travel information can be stored in previously stored map information using a new storage device such as an optical disk storage device, an optical card storage device, or a semiconductor memory, and can be recalled as needed. The aim is to provide the driver with information necessary for driving based on driving state information.

[Effect]

The write-once storage device of the present invention newly stores travel routes, planned travel routes, targets, etc. in read-only memory information such as maps, and in addition to storing return route, re-travel route, travel route instructions, etc., current position information, The system supports the driver's driving by calling up information such as distance traveled, time remaining, targets on the route, etc., in response to the driver's request.

〔Example〕

Hereinafter, one embodiment of the present invention will be explained with reference to the drawings.
In the figure, (1) to (5) are the same as those in the conventional embodiment shown in FIG. 2, and will therefore be omitted. (6) is a magnetic memory device that can store unchangeable or nearly unchangeable information such as map information as read-only memory information, and can also store new driving information, targets, planned driving routes, etc.

These are storage devices such as optical disk storage devices, optical card storage devices, and semiconductor memories.

In the above configuration, when traveling, the map of the planned trip is first retrieved from the storage device (6), and information such as the current position, the direction at the start of the trip, and the conversion constant of the crosspiece to be used is input to the CPU using the manual input device (2). Enter in (5). When driving starts, the direction detector (8) and axle-mounted tachometer (4)
Based on the sensing information of the driver, the cPU (5) performs arithmetic processing, displays the current position and driving route on the display (1), and stores it in the storage device ( 6) This allows us to provide accurate driving information to the driver by recalling this information on the return trip or re-driving, and also to store the planned driving route etc. in advance in the memory device ( By adding the information in 6), it is possible to provide the driver with the necessary information even on the first driving route.

In the above embodiment, an axle-mounted tachometer is used as the distance or speed calculating sensor, but the same effect can be obtained by using an absolute speed detector such as a radio-controlled Dragura speedometer or a Reza Doppler speedometer.

〔Effect of the invention〕

As described above, according to the present invention, the information on the map is called up at the time of re-driving and the first driving, and the current driving information is combined and displayed, thereby making it more accurate. This has the effect of providing drivers with accurate and timely information.

[Brief explanation of the drawing]

FIG. 1 is a block diagram of a drive guide device according to an embodiment of the present invention, and FIG. 2 is a block diagram of a conventional drive guide device. (1) is a display, (2) is a manual input device, (8) is a direction detector, (4) is an axle-mounted tachometer, (5) is a CPU,
(6) is a storage device. In addition, the same symbols in the figure are the same, or 0 indicates the priest part.

Claims (1)

[Claims] A direction detector that detects the running direction of the vehicle, a distance detector that detects speed or equal distance information, an input device that inputs information, and a display based on the detection information of each detector and the input information from the input device. The drive guidance device is equipped with a central processing unit that provides driving information on the vehicle, and is equipped with a storage device that can store map information in advance and store new driving information such as the driving route based on the map information, so that it can be used on the way home or when re-driving. A drive guidance device characterized in that the driving information can be called up while driving.
