The sensor fusion of gyro controller system for the smart vehicle

Nowadays, the GPS (Global Positioning System) is generally used for the car navigation system but it has some restrictions such as the discontinuity of Earth satellite's signals and artificial errors called SA (selective availability). To solve these problems, the INS (inertial navigation system) sensor fusion with GPS is very attractive for improving the accuracy of detecting a vehicle position. The DR (dead reckoning), which is one form of the INS uses a wheel magnetic sensor for the driving distance and a gyro sensor for the vehicle orientation. The black-box, which is the most important record after a car accident, contains data from acceleration sensors and a gyro sensor. In this paper, gyro controller system using single-chip microprocessor (i80c196kc) is developed for the DR and black-box.
