Abstract
The present invention provides a method and apparatus for recording vehicle motion. The self-contained vehicle motion recorder apparatus (10) is a sealed unit that contains at least a power source (30), a controller (14), sensors (12), and recording devices (38, 44).
The controller device (14) includes a power consumption manager (28) that manages and conserves the overall power consumption of the apparatus (10). The sensor device (12) is further included in operable communication with the controller device (14) that produces signals that represent the vehicle's motion as a function of time. The recording devices (38, 44) are provided in operable communication with the controller (14) for storing data that correspond to the signals. A
communication interface (not shown) is further provided such that data may be read from the apparatus (10) and commands and data may be written into the apparatus (10) from an external device (not shown).
