1. A vehicle onboard monitoring system for monitoring vehicle driver performance comprising:

  • (a) a system processor including a microprocessor and a data storage medium coupled to said microprocessor, said microprocessor including means for controlling said vehicle onboard monitoring system and processing vehicle operation data, said means for controlling said vehicle onboard monitoring system including means for input of a current vehicle odometer reading thereto for storage in said data storage medium responsive to energization of said system processor;

    (b) a plurality of vehicle sensors coupled to said system processor for input thereto of said vehicle operation data, each of said vehicle sensors transducing an operation parameter of a vehicle component responsive to predetermined vehicle operation data sensed thereby, said means for controlling said vehicle onboard monitoring system including means for performing integrity tests responsive to energization of said system processor, said means for performing integrity tests comparing said current vehicle odometer reading with a determination of total distance previously traveled to detect a first tampering condition;

    (c) signal interfacing means coupled to said vehicle sensors and said system processor for filtering and formatting data to be transferred between each of said vehicle sensors and said system processor;

    (d) power conversion means coupled to said system processor for converting a vehicle electric power signal format to drive said system processor and said vehicle sensors;

    (e) vehicle mounting means coupled to said system processor for operation of said vehicle onboard monitoring system, said vehicle mounting means including means for simultaneously coupling said system processor with said vehicle electric power signal and with said vehicle sensors, said vehicle mounting means having an electronically readable identification code unique to said vehicle, said means for performing integrity tests comparing said electronically readable identification code with a stored code to detect a second tampering condition; and

    ,(f) playback means adapted to be coupled to a remote computer and said system processor for digital communication between said remote computer and said system processor.
