Vehicle monitoring system

An on-board, dash mounted, vehicle monitoring system for real-time monitoring of a plurality of functions and conditions effecting a vehicle's performance and providing a graphic presentation and recordation of torque, RPM, and horsepower, and reporting transmission torque, inclination, headwind, barometric pressure, and ambient temperature effecting a vehicle's performance, said vehicle including a plurality of internal and external sensor means for producing sensor signals corresponding to said plurality of functions and conditions, said monitoring system comprising:

• processing means responsive to said sensor signals for producing display signals corresponding to said functions and conditions, converting said functions and conditions to torque and horsepower, controlling digital and graphic displays, and concurrently producing and displaying signals corresponding to manufacturer established design upper limits comprising, maximum intended torque, maximum intended RPM, and percentage of horsepower being used,
• digital display means mounted in said dashboard for presenting a first group of functions and conditions effecting a vehicle's performance, and the percentage of horsepower being used,
• graphic display means mounted in said dashboard for presenting and recording concurrently, a second group comprising torque output, revolutions per minute, system status, horsepower effecting said vehicle's performance, and manufacturer established design upper limits, comprising, maximum intended torque, maximum intended RPM and percentage of horsepower being used,
• throttle open switch means for activating said processing means to provide vehicle and horsepower plotting sensor signals to selected graphic display means when torque plotting conditions are met, and
• switch means for clearing said graphic display means after torque, horsepower, and manufacturer established design upper limits, comprising maximum intended torque, maximum intended RPM, and percentage of horsepower used, plotting has occurred.
