Abstract
Apparatus and method for logging data corresponding to the motion of a vehicle. Programmable variables in the logger are set when it is connected to a remote indicating device. The logger is then installed in the vehicle and connected to power and motion sensor lines. The logger monitors electrical signals from the motion sensor and determines the relative speed of the vehicle. Information is stored in the memory of the logger for each stop of the vehicle. Such information may include the maximum speed since the last stop, the distance, date, and time the maximum speed occurred, and the distance, date, time, and duration of the stop and any short intermediate stops. The logger contains circuitry for merging together information data groups for each stop in the memory, thereby allowing the longest stops to define the boundaries of the data information groups. After the information is stored in memory, the logger may be removed from the vehicle and reconnected to the remote indicating device for transfer of the memory data and for displaying or printing of the processed data.
