Abstract

In accordance with a method of and arrangement for representing point-referenced travel guiding information, especially in power vehicles on a display of an electronic guiding and orienting device, a desired travel route is input, and a travel guiding information is represented at a distance from a reference point determined in accordance with the vehicle speed.

Claims

1. A method of representing point-referenced travel guiding information on a digitalizer screen forming a display of an electronic guiding and orienting device of a vehicle, said method comprising the steps of inputting a desired travel route on the digitalizer screen before start of travel along the desired travel route;

representing the travel guiding information on the digitalizer screen at a distance from reference points including representing first travel guiding information required for a first reference point and second travel guiding information required for a second reference point;

blocking the second travel guiding information for such a time until the vehicle reaches the first reference point for which the first travel guiding information is required; and

adjusting the distance linearly in accordance with an instantaneous speed of the vehicle so that the distance increases with an increase of the instantaneous speed of the vehicle.

2. A method as defined in claim 1, wherein said blocking step includes blocking until the vehicle passes the first reference point which has been fixedly predetermined before start of travel along the desired travel route.

3. A method as defined in claim 1, wherein said blocking step includes blocking until the vehicle passes the first reference point which is predeterminable during travel along the desired travel route.

4. A method as defined in claim 1, wherein said representing step includes representing the travel guiding information in form of a directional arrow on the display.

5. A method as defined in claim 1, wherein said representing step includes representing on the display the travel guiding information in a primary field of vision of a vehicle driver.

6. An arrangement for representing point-referenced guiding information, comprising a digitalizer screen forming a display on which a desired travel route is input before start of travel along the desired travel route;

means for sensing instantaneous speed of a vehicle moving along the desired travel route;

means for representing travel guiding information on the digitalizer screen at a distance from reference points including first travel guiding information required for a first reference point and second guiding information required for second reference point, said representing means including a blocking device for blocking representation of the second travel information required for the second reference point until the vehicle passes the first reference point for which the first travel guiding information has been provided; and

means for adjusting the distance lienarly in accordance with an instantaneous speed of the vehicle.

7. An arrangement as defined in claim 6, wherein said representing means is formed so that the travel guiding information is represented as an arrow which shows a desired travel direction corresponding to the desired travel route.

8. An arrangement as defined in claim 7, wherein said representing means represents the travel guiding information on the display in a primary field of vision of a vehicle driver.
