〔Example〕

The details of the present invention will be explained based on illustrated embodiments.

FIG. 1 is a diagram illustrating complaints regarding the electronic taximeter according to the present invention.

Reference numeral 1 in the figure is a navigation system that determines the vehicle position on map data stored in a storage medium.

Navigation systems are divided into two types: an absolute position detection method that detects the absolute position by receiving radio waves from signposts and satellites, and a relative position detection method that constantly detects the ever-changing vehicle speed and direction to determine the current position relative to the starting point. There is.

Among the absolute position detection methods, those that use sign posts are equipped with a radio wave source on the road that transmits position information to the vehicle.
From this, each vehicle obtains current vehicle position data.

In addition, Global Po is a method that uses satellites.
There is something called GPS positioning system (hereinafter referred to as GPS).

In other words, the distance to the satellite is measured from the propagation time of radio waves sent from at least three of the multiple satellites (for example, 18) in orbit at an altitude of about 20,000 km, and the position where the distances intersect at the - point is determined. This method is used to obtain vehicle position data.

The relative position detection method detects the running direction of the vehicle using a gas rate sensor, geomagnetic sensor, left and right wheel speed difference sensor, vibration gyro, etc., and detects the vehicle speed using a wheel speed sensor.
It is used to know the route from the starting point.

In either case, a storage medium is provided in which map data is stored, and this storage medium is usually a CD-ROM.

Here, an example of a relative position detection type navigation system is shown in FIG. 2 as a simplified bronc diagram.

11 is a storage medium C in which map data is stored;
The DROM is inserted into a CD-ROM drive and map data is read out.

13 is a position measuring sensor such as a gas rate sensor, a geomagnetic sensor, a left and right wheel speed difference sensor, a vibration gyro and a wheel speed sensor, and a signal from this position measuring sensor 13 is input to an inertial navigation unit 14.

The inertial navigation unit 4 calculates the current position and direction based on the signal from the position measurement sensor 13, and calculates the current position and direction based on the signal from the position measurement sensor 13.
send to

The position recognition unit 15 creates trajectory data based on the vehicle position data sent from the inertial navigation unit 14, and performs map matching by comparing it with the map data read by the CD-ROM drive 12.

Map matching is performed by the position recognition unit 15 and the corrected data is sent to the man-machine interface 16.

The man-machine interface 16 sends the map data read by the CD-ROM drive 12 and the vehicle position data from the position recognition unit 5 to a display means 17 such as a CRT display, and displays them on the screen.

In FIG. 1, reference numeral 2 denotes an electronic taximeter according to the present invention, which includes a tariff setting input means 3 consisting of a plurality of switches for setting tariffs such as vacant, rental, surcharge, pick-up, etc.; A display means 4 for displaying the fare, the current tariff position, etc., a RAM 5 in which various travel data are temporarily stored, and a fare calculation according to the current tariff position based on the travel distance and travel time, A data processing means 6 for displaying the current price on the display means 4, and a ROM 7 for storing operating programs, various parameters, etc.
It has the following.

FIG. 3 is a simplified diagram showing an embodiment of the present invention.

Reference numeral 23 denotes a tariff setting input means for setting the tariff position when traveling, and is composed of a plurality of buttons for instructing fare control such as rental run, surcharge, pick-up, payment, etc. It is attached integrally with the display device 24 provided on the front of the meter.

24 is a display device for displaying charges, tariffs, etc., and a fluorescent display tube, a light emitting diode, a liquid crystal display board, or the like is used.

Reference numeral 25 is a RAM for temporarily storing travel data of the taxi vehicle.The data stored in this RAM includes the business date, car number, driver code, total travel distance, actual vehicle travel distance, and vehicle travel data. There are the number of times, the number of times the charges are added after that, other indexes on the day, the distance traveled for each business, the time required, the tariff position at that time, the distance traveled when the vehicle is empty, the time required, etc.

26 is a central processing unit (hereinafter referred to as CPU) that performs charge calculations, data input/output control, etc., and performs each process according to a program stored in the ROM 27.

FIG. 4 is a flowchart of the present invention.

That is, when the tariff setting input means 23 is operated while the vehicle is running empty, the CPU 26 calls the current vehicle position data from the position recognition unit 15 shown in FIG. 2 of the navigation system 1, for example.

Thereafter, a fee calculation is performed according to the operated tariff position, and the operating fee at that time is sequentially displayed on the display device 24.

When the commercial driving is finished and the vehicle becomes vacant, the display device 24 is reset and the current vehicle position data is read again from the navigation system 1.

Next, the distance traveled during the business, the time required, other tariff positions, and vehicle position data at the start and end of the business are stored in the RAM 25.

When the taxi vehicle returns to the business office or the like, a cable is connected to a data input terminal (not shown) provided on the tough saw meter, and the data is transferred to a data processing device provided at the business office.

This data is stored in an external storage device or transferred to a host computer or the like for analysis.

At this time, since vehicle location data is attached to each business data, it is possible to recognize from which point on the map each business is located, and based on this, a travel log is created and printed out. It is something that can be done.

Here, various business driving data are displayed on the R in the taxi meter.
Although the case where the data processing device is stored in the AM is shown, if the data processing device is separate from the taximeter, the vehicle position data is stored in the data processing device along with the traveling data, and there is no particular limitation.
