1. An on board truck operation monitoring system a portion of which is mounted in a truck cab and which comprises:

  • a plurality of sensors, each positioned to sense an operating parameter of the truck;

    a primary instrumentation module including primary instrument gauges mounted in the truck cab and data processing means comprising microprocessor means and memory means including a RAM and ROM for processing data in accordance with an instruction set stored in said ROM, means for coupling said sensors to said microprocessor means, display means coupled to said microprocessor means for displaying operating parameter data such as data generated by said sensors, and said RAM and ROM being coupled to said microprocessor means for storing said operating parameter data from said sensors in said RAM and said instruction set in said ROM;

    operator input means for actuating said microprocessor means for selectively displaying data on said display means, for altering and executing portions of the instruction set, for inputting operator data and for selectively displaying operating parameter data;

    said operator input means further including a cab mounted driver interface module coupled to said primary instrument module and including a panel having a driver interface display for displaying said operator data and a driver interface keyboard on said panel including number keys, specific function keys and programmable function keys for inputting said operator data into said memory means;

    radio frequency link means for communicating at least said operating parameter data and said operator data from said memory means to a larger off board data processing apparatus,said larger off board data processing apparatus comprises radio transmitting and receiving means for polling said radio frequency link means for automatically retrieving data from said memory means, andsaid microprocessor means including means for carrying out a self diagnostic mode of operation of the system in which all the sensors are checked to see if they are working properly and in which said radio frequency link means for communicating from said memory means to the larger off board processing apparatus is checked to make certain it is functioning properly.
