[Title <strong>of</strong> the Invention]<br />
Measuring instrument <strong>for</strong> traverse <strong>for</strong> vehicles<br />
[Claims]<br />
1. A measuring instrument <strong>of</strong> traverse <strong>for</strong> vehicles to display the present position <strong>of</strong> a vehicle<br />
by calculating the travel bearing and mileage <strong>of</strong> vehicles, having an angle sensor (3)<br />
detecting the angle <strong>of</strong> steering wheel, a means <strong>of</strong> calculating the traveling bearing<br />
mentioned above according to the angle detected by the angle sensor (3) and the fixed<br />
initial value. (See Figure 1)<br />
2. A measuring instrument <strong>of</strong> traverse <strong>for</strong> vehicles to display the present position <strong>of</strong> a vehicle<br />
by calculating according to traveling bearing and mileage <strong>of</strong> vehicles, having magnetic<br />
compass (1) detecting the traveling bearing <strong>of</strong> vehicles, a means <strong>of</strong> calculating traveling<br />
bearing (27) <strong>of</strong> vehicles according to the angle <strong>of</strong> a steering wheel detected by the angle<br />
sensor (3) and the fixed initial value, a means <strong>of</strong> calculating a position (5) which indicates<br />
the present position <strong>of</strong> a vehicle by switching the bearing detected by the magnetic compass<br />
to the traveling bearing according to the angle detected by the angle sensor when the error<br />
is more than the specified value. (See Figure 2)<br />
3. A measuring instrument <strong>of</strong> traverse <strong>for</strong> vehicles having a means correcting the present<br />
position <strong>of</strong> a vehicle calculated according to the bearing detected by the magnetic compass<br />
to the position detected according to navigation radio, and a measuring instrument <strong>of</strong><br />
traverse <strong>for</strong> vehicles which switches to the position calculated by the traveling bearing<br />
calculated according to the angle when the receiving level <strong>of</strong> the above navigational radio is<br />
below the specified value. (See Figure 3)<br />
[Excerpt from Detailed Description <strong>of</strong> the invention and Drawings]<br />
This invention related to a measuring instrument <strong>of</strong> traverse <strong>for</strong> vehicles, which indicates<br />
the present position <strong>of</strong> a vehicle by calculating according to traveling bearing and mileage. The<br />
traveling bearing <strong>of</strong> vehicles is calculated according to the angle <strong>of</strong> a steering wheel, and<br />
detecting the position according to navigational radio and detecting by magnetic compass are<br />
considered <strong>for</strong> indicating the position regardless <strong>of</strong> abnormal radio and magnetic activities.<br />
