<p>PROBLEM TO BE SOLVED: To provide a controller of a hydraulic power steering device capable of raising steering F/L by making operation states of first and second electric pumps the same when the first electric pump detects an abnormality and the second electric pump is actuated.SOLUTION: A controller of a hydraulic power steering device is constituted by comprising control means for controlling actuation of a hydraulic ACT, in which the control means has a velocity F/B control part, and a current F/B control part with proportion and integration, the control means comprises integration state quantity storage means for storing integration state quantities of the velocity F/B control part and the current F/B control part of the first and second electric pumps, the control means reads the integration state quantities of the velocity F/B control part and the current F/B control part before the first electric pump detects an abnormality from the integrated state quantity storage means when the first electric pump is under actuation, the second electric pump is under stop, and the first electric pump detects the abnormality, and starts the actuation of the second electric pump after tracing the read integration state quantities to the integration state quantity storage means of the velocity F/B control part and the current F/B control part of the second electric pump.</p> |
