Latest Patents
One of Doi's latest patents is a vehicle location detecting system. This system includes a calibration apparatus for an angular velocity sensor used in self-contained navigational systems. The apparatus features an angular-velocity detection unit that calculates angular velocity from the sensor's output signal. It also has an integration unit that determines the vehicle's current heading by integrating the angular velocity and adding it to the previous heading. Additionally, a location and heading detection unit estimates the vehicle's location using data from a magnetic sensor and a distance sensor. This unit compares the estimated location with road network data to refine the vehicle's heading. Finally, a heading correction unit calculates the difference between the integration unit's heading and the detection unit's heading, integrating this difference to provide a correction value for the current heading.
