Abstract
A vehicle steering assist system, including an engine pump, a flow-rate restricting mechanism, a motor pump, a motor-pump controller, and a steering-force assist device, wherein the steering assist system is configured to restrict an engine-pump ejection flow rate to be lower than a required receiving flow rate to be received by the assist device when the engine pump is operated by being driven by an engine rotating at an idling speed, the engine-pump ejection flow rate being a flow rate of a working fluid ejected from the engine pump to the assist device via the restricting mechanism, and wherein the motor-pump controller is configured to control a motor-pump ejection flow rate such that an insufficient flow rate of the working fluid is covered by the motor-pump ejection flow rate, the insufficient flow rate being a shortage in the required receiving flow rate not covered by the engine-pump ejection flow rate.
