Abstract:

Systems and methods for recording information in a vehicle data recorder device. The vehicle data recorder device includes an inertial measurement unit (IMU), a crash survivable unit having memory, and a microcontroller in data communication with the IMU and the memory. The microcontroller receives angular rate information and acceleration information from the IMU and stores the received angular rate information and acceleration information in the memory. The IMU includes two or more MEMS gyroscopes or ring laser gyroscopes. In one example, the microcontroller stores angular rate information and acceleration information in the memory until a threshold event has occurred. The threshold event includes at least one of the angular rate information or acceleration information indicating zero with respect to a rotating earth coordinate frame for a predetermined period of time.
