  • Patent number: 6141610
    Abstract: A method and apparatus that allows for monitoring the operation and usage of a vehicle. A data logger is installed in a vehicle to be monitored. The data logger couples to the vehicle's electronic system and monitors data relating to usage and condition of the vehicle. In one embodiment, the data logger includes a position determining system for determining whether the vehicle has traveled outside of a predetermined area and accelerometers for determining whether the vehicle has been involved in a collision. The data logger transmits information relating to the condition and usage of a vehicle each time that a vehicle return to a facility. The information relating to the condition and usage of the vehicle is then coupled to a computer. This allows for easily monitoring the usage and condition of vehicles without requiring manual data entry.
