Pressure Control Calibration Time Reduction for EHB Systems

An ABS/TC proportional pressure control can be achieved by using some of the control technology applied to an electro-hydraulic brake (EHB) system. This paper describes a new method for reducing the calibration time of an EHB, and this method may be used for potential advanced ABS/TC proportional control systems. A mathematical model is established to analyze the system and by using the model some common physical relationships are identified. Calibration values of a proportional system in certain pressure ranges can be estimated instead of requiring measurement.
