MIMU measuring unit and based on the adaptive control method of the headlamp

The present invention discloses a micro-inertial measurement unit and the measurement method of adaptive headlamp control unit based, for solving the conventional method of controlling an adaptive headlamp technical problem of poor security. Technical Solution micro inertial measurement unit includes an X-axis gyroscope, Y-axis gyro, Z-axis gyroscope, a three-axis accelerometer, a magnetoresistive sensor, signal conditioning boards and microcontroller, the inclined angle of the gyro sensing gamma], ψ yaw angle and the pitch angle signal θ triaxial accelerometer output value of gravitational acceleration of the vehicle body in the three-dimensional space. Gamma] inclination angle, yaw angle and the pitch angle θ ψ signal, and the value of gravitational acceleration is conditioned by the signal conditioning unit, into the microcontroller fused to give accurate gamma] inclination angle, pitch angle and yaw angle ψ and θ change signal rate signal, the microcontroller gamma] according to the inclination angle, pitch angle and yaw angle ψ and θ signal rate of change signal, the control information into the host computer control. Since the present invention is robust to the accumulation of errors, such that reliable control of the headlamp.
