While some features disclosed within the related art are incorporated into this invention in combination, other elements are different enough as to make the combination distinguished over these, and other references. Consequently, a need has therefore been felt for an improved mechanism that provides a method and system of recording the ground speed of a motor vehicle for reviewing at a later time to verify operation of said motor vehicle.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide an improved motor vehicle speed monitoring system.
It is another object of the present invention to allow owners or caretakers of motor vehicles to review the operating parameters of their motor vehicles when not under their direct observation.
It is a feature of the present invention to encourage safe operating practices of others' motor vehicles by knowing that the owner or caretaker will be able to determine the maximum operating speed of the motor vehicle.
In accordance with a preferred embodiment, a motor vehicle speed monitoring system is a device that interfaces to a speed detection instrument to allow the recording of a motor vehicle speed in an unattended manner. Such monitoring allows for the security that one's children, employees, valets, mechanics, or others entrusted with the care of a vehicle have not operated it above acceptable speed limits. The system digitally records the top speed of the vehicle every time it is started and keeps a log of the speed and the time and dates at which it occurred. The owner or authorized user may review the internal log by entering a password key into a keypad.
An advantage of the present invention is that it is able to operate independent from the vehicle's battery.
Another advantage is that the electrical components operate the system automatically without the activation or even the knowledge of the driver.
