Title:
VALVE CONTROL DEVICE AND VALVE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/152970
Kind Code:
A1
Abstract:
A valve control device for controlling a valve drive mechanism on the basis of a valve degree-of-opening signal and an engine startup signal, said valve control device being equipped with: a drive signal generation unit that, when starting of the engine is determined on the basis of the startup signal, generates a test drive signal for test-driving the valve before the generation of a normal drive signal associated with normal driving of the valve; and a fault determination unit that, on the basis of a degree-of-opening signal during the test driving, determines whether a fault has occurred in the drive mechanism. The drive signal generation unit stops generating the test drive signal and the normal drive signal when the fault determination unit determines that a fault has occurred in the drive mechanism.
