SUMMARY OF THE INVENTION An object of the present invention is to provide a navigation system that can recognize not only the current position and travel trajectory of a vehicle but also changes in vehicle speed and fuel consumption rate in the blink of an eye.

The means to solve the problem is to detect the azimuth of the azimuth sensor 1g and the speed of the azimuth sensor that detects the azimuth of the vehicle relative to the earth's magnetic field.Display the current position and trajectory of the vehicle. In a navigation system that continuously displays a driving condition, a driving condition sensor that detects the driving condition and issues a driving condition signal is provided, and the driving trajectory is determined according to the driving condition signal of the driving condition sensor. 1゜

Effects □ By employing the above configuration, the present invention can display the progress of past driving conditions, such as changes in average vehicle speed and fuel consumption rate, by changes 7 in the display color or line type of the driving trajectory.

Example An embodiment of the invention will now be described with reference to schematic diagrams.

In Fig. 1, 1 is a direction sensor that detects the running azimuth of the own vehicle relative to the earth's magnetic field and issues an azimuth signal; 2 is the above-mentioned direction sensor; A direction calculating circuit 3 converts the vehicle speed into a coordinate component signal, a vehicle detects the vehicle speed and issues a vehicle speed signal, and a speed sensor 4 generates a mileage signal every time the vehicle travels a predetermined distance from the vehicle speed signal from the vehicle speed sensor 3. When the rectangular □ coordinate component signal of the direction/' calculation circuit 2 and the travel distance of the vehicle speed calculation circuit 40 are inputted to the travel trajectory calculation circuit 5, the corresponding The driving trajectory calculation circuit 5 calculates the own vehicle and
The current position and driving direction of the vehicle are calculated, and the driving trajectory and traveling direction of the vehicle are displayed via the drive circuit 6.
The display device T is designed to continuously display a constant distance traveled. The display is equipped with display elements capable of displaying colors such as the following, and is constructed so that a color display can be performed by input signals to the drive circuit 6.

Jinsei, 7p, and 1 showed a system in which the line was made to run silently, but a fuel consumption rate sensor was installed to detect the fuel consumption rate and emit different signals depending on the range of the nuclear fuel consumption rate. The information may be displayed by color or line type depending on the size of the extinction rate.

Effects of the Invention The present invention calculates the azimuth signal of the azimuth sensor that detects the running azimuth of the own vehicle relative to the geomagnetic field and the vehicle speed signal of the vehicle speed sensor that detects the vehicle speed, and displays the current position and traveling trajectory of the own vehicle on the display unit. In a navigation system that continuously displays a driving condition, a driving condition sensor is provided which detects the driving condition such as average vehicle speed or solvent consumption rate and issues a driving condition signal, and the driving condition signal of the driving condition sensor is Since the display color or type of display line of the driving trajectory can be adjusted accordingly, by viewing the driving path displayed on the display device, you can see how the average vehicle speed and fuel consumption rate have changed over time. In addition to being able to understand whether the vehicle has been driven on an expressway or on an ordinary road, various information that can be used as a reference for future driving can be accumulated, and the configuration is simple. This can bring about great effects.
