Title:
陸ベース車両の作動点を正確に求めるためのコンピュータベースのシステム
Document Type and Number:
Japanese Patent JP3837160
Kind Code:
B2
Abstract:
A computer-based system (100) for precisely determining an operating point for a land-based vehicle includes a receiver (216) mounted on the vehicle for receiving navigation signals from a satellite-based positioning system (218), an odometer (230) for measuring distance travelled by the vehicle, a doppler radar (232) for measuring ground speed of the vehicle, a solid-state rate sensing device (234) for measuring the heading rate of the vehicle, and a resolver (236) for measuring the steering angle of the vehicle. An extended Kalman filter (208) combines the measurements of these sensors (216, 230, 232, 234, 236) to produce a highly accurate estimate of the vehicle's operating point. The operating point includes an estimated north position, an estimated east position, an estimated heading, an estimated heading rate, and an estimated speed.
