Description of EP0964166
[0001] The present invention relates to hydraulic control systems such as those used in the control of vehicle active suspension systems.
[0002] It is known to provide closed loop pressure control in a hydraulic system by monitoring the hydraulic pressure at a point in a hydraulic circuit, comparing the measured pressure with a desired pressure, and controlling the electrical current to an electrically operated valve, such as a solenoid valve, to open or close the valve to adjust the pressure in the system towards the desired pressure.
[0003] It can be a problem with such systems that known pressure transducers have a temperature dependent characteristic, so the exact hydraulic pressure cannot be accurately measured.
