Abstract:
A hydraulic power steering unit has an assist force generating unit that uses oil to generate assist force for steering by a steering device, a variable flow oil pump unit that supplies oil to the assist force generating unit, and a controller that controls the oil pump unit. The controller has a command flow setting device that sets a command flow rate Qc of the oil supplied from the oil pump unit to the assist force generating unit in accordance with a vehicle quantity of state such as a vehicle speed, steering angle or the like. The controller also has a flow correcting device that corrects the command flow rate Qc in accordance with the speed of the oil pump unit.
