Abstract

PURPOSE:To obtain a display device enabling the recognition of a moving direction and a moving distance from a starting point, by a method wherein the divisions of a scale around the starting point as the center are marked on the display of an actual running course of a display unit in a trial which is a motor sport, and the like. CONSTITUTION:An operating input button 1 operates for starting and stopping the operation of a device, for setting a starting point S and an ending point G of a track, etc. A grid pattern generator 4a generates a grid pattern variable in a rate of multiplication around a base point S in a controller 4. When a switch is put on, a figure denoted by (A) is displayed in a display deice 6, and when the button 1 is pushed, the indication S flickers in the center and a grid (having meshes of width 250M) is given around the point S. The track is drawn as shown in (B) according to a running state. When a position showing a running point is beyond 500M in both directions X and Y, a scale is doubled as shown in (C), and further it is doubled each time when the position is beyond 1,000M and 2,000M. When a destination is reached, the button 1 is pushed again, and then an indication G indicating a goal is made as shown in (D). This means that a course of a dirt trial is set.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a travel route data display device that can be used in a motor sports trial assistance system and the like.

(Prior Art) Many proposals have been made and implemented regarding so-called driving assistance systems that display a map including a driving route on a display panel inside a vehicle.

In addition, the applicant has developed a vehicle navigation system (Japanese Patent Laid-Open No. 60-1202) that can calculate and display the accurate distance between two points by adding corrections for altitude to the distance traveled by the vehicle.
No. 08), etc.

(Problems to be Solved by the Invention) In trials and the like that are motor sports, there are a wide variety of types and locations of trial courses, and it is not very meaningful to simply be able to display a map or display distances, etc.

An object of the present invention is to provide a travel route data display device that allows the user to recognize the moving direction and travel distance from the starting point by putting a scale centered on the starting point on the display of the actual running course. It's about doing.

(Means for Solving the Problems) In order to achieve the above object, the travel route data display device according to the present invention takes in data from a distance sensor and a direction meter every unit time and calculates the current position using a controller. In the travel route data display device, the controller is provided with a grid pattern generator with variable magnification that generates data centered on a reference point, and the controller is equipped with a grid pattern generator that generates data centered on a reference point, and outputs the data and displays it on the screen of the display device. When the magnifications of the patterns are compared and the current position exceeds a certain ratio, the magnification of the display point is changed together with the magnification of the grid pattern generator.

(Example) Hereinafter, the present invention will be described in detail with reference to the drawings and the like.

This embodiment is designed to assist in trials.

If this device is installed, trial competitions can be held anywhere rather than on a specific course.

FIG. 1 is a block diagram showing a travel route data display device according to the present invention.

The operator capotan 1 is an input means for starting and stopping the device, setting the starting point (S) and ending point (G) of the trajectory, etc.

The distance sensor 2 is a sensor that inputs distance data.

The direction meter 3 is a means for inputting data regarding direction.

The controller 4 is an arithmetic control circuit formed around a CPU, and the output of this circuit is inputted to a display device 6 via an interface 5 and displayed.

Next, the basic principle of how to determine the movement locus (movement position) in this device will be briefly explained.

The moving distance per unit time (from i-1 seconds to i seconds) is Li
shall be.

This Li (scalar N) is obtained from the distance sensor 2 mounted on the vehicle.

Furthermore, if the direction of travel of the vehicle is θi (based on true north N) from the azimuth data input from the direction meter 3, then from i-1 seconds, the vehicle is expressed by the following formula (x i+
It has moved by y i).

xi=Licosθi yi=Li sinθ
iUsing this calculation formula, Pi (/xi.

fyi) The movement trajectory to the point is expressed as fXi = xi + 1xi-1 (fXo = 0)/Yi = yi + Jyi-1 (fYo = O).

This calculation is performed every time, and the display device 6 is driven via the interface 5 to display the movement trajectory to the point Pi.

Next, the display will be mainly explained with reference to FIG.

(2) When the power switch is turned on, the screen shown in FIG. 3(A) is displayed on the display device 6.

■ When the setting button on the operation input device 1 is pressed, the S display flashes in the center.

A grid (scale line) is placed on the screen centered on the starting point.

Courses can be set from Konohei.

According to the driving condition, as shown in FIG. 3(B), the display draws a trajectory on the screen.

The width of the initial grid is every 250M.

When the distance traveled exceeds 500M in either the X or Y direction, the scale of the grid is increased as shown in FIG. 3(C).

That is, when the position indicating the travel point exceeds 500M in the X or Y direction, the scale of the grid is doubled as shown in FIG.

Below, if it reaches 1000M or more, double the amount, 2000
When it reaches M or more, double it again.

■ When you reach your destination, press the setting button again and the screen shown in Figure 3 (
As shown in D), G is displayed to indicate the destination point (goal).

With this, the course for the dirt trial has been set. A stopwatch will appear.

Figure 2 shows the CPU of the controller when setting the course.
2 is a flowchart showing the operation of FIG.

(Step 100) The power is turned on and started, and a setting standby state is established.

(Step 101) Check whether the setting button has been pressed or not. Waits until the settings button is pressed.

(Step 102) When the setting button is pressed, a 250M grid pattern (basic pattern) is displayed on the display device 6.

(Step 103) It is stored that the first grid pattern is displayed (n-1).

(Step 104) Calculate the X and Y components of the travel distance for each basic unit time. Depends on Li and θi mentioned above.

(Step 105) It is determined whether the current X coordinate and X component from S exceed 500M.

If it has passed, proceed to (107).

(Step 106) It is determined whether the Y coordinate and Y component from S at the current time exceed 50°M.

If it has passed, proceed to (107).

(Step 107) Change the magnification. In the current example, n is 1+1 or 2.

(Step 108) The grid spacing is set to 250Xn, 500M in this example.

(Step 109) The display magnification of the points on the travel trajectory is reviewed according to the previous n or the changed n, and if there is a change, it is changed.

(Step 11o) Monitor the settings button until the settings button is pressed (10
4-110).

(Step l11) The setting button is monitored, and when the setting button is pressed, the course setting is completed, the goal G is displayed, and the process waits.

(Effects of the Invention) As described in detail above, in the traveling route data display device according to the present invention, the controller is provided with a grid pattern generator whose magnification is variable and generates data centered on a reference point.

Therefore, the driver can accurately recognize the current position in relation to the grid pattern.

Furthermore, the travel route data display device according to the present invention compares the current position and the magnification of the pattern of the grid pattern generator at that time, and when the current position exceeds a certain ratio, the travel route data display device It is configured to change the magnification of the display point.

Therefore, it is possible to display images by effectively utilizing the display screen of the display device.
