Patent abstract
Vehicles equipped with air brake systems and onboard vehicle management computers are programmed to develop both a prognosis and diagnosis of problems in the supporting, compressed air supply system from monitoring compressed air supply tank pressure. Variance of measured pressure from established norms correlated with the frequency and duration of charging cycles as well as brake pedal position provides indication of the likely source of present and future problems.
