摘要： A flow controlling apparatus to control flow rate of working fluid discharged from pump apparatus to a power steering apparatus including a electric variable throttle (2), a solenoid mechanism (5) and a spool (1). The solenoid mechanism varies opening degree of the electric variable throttle based on a electric signal from electric controller (55). The spool slides in accordance with the differential pressure of the variable throttle due to increase of flow rate of working fluid discharged from pump apparatus so as to return excess working fluid to bypass passage connecting to a suction port of pump apparatus. The flow controlling apparatus further comprising means for increase flow rate of bypass flow to bypass passage (72) when rotating speed of the pump apparatus exceed predetermined value.

摘要： A variable steering ratio mechanism varies the ratio R of the steering angle θs of a steering wheel to a road wheel steer angle θw. A control unit controls the variable steering ratio mechanism so that the steering ratio R is kept constant irrespective of the vehicle speed V when the steering angle θs is less than or equal to a predetermined angle θ 1 substantially corresponding to a neutral position of the steering wheel. In particular the control unit may switch the variable steering ratio mechanism to a non-control state to maintain the steering ratio R at a structurally-determined steering ratio of the variable steering ratio mechanism kept in the non-control state when θs ≤ θ 1 . The control unit may have a processor programmed to (a) execute a fixed steering ratio control mode, in which R is kept constant irrespective of V, when θs ≤ θ 1 , and (b) executing a vehicle-speed dependent steering ratio control mode, in which a θs versus θw characteristic varies depending on V, when θs > θ 1 .

摘要： The invention relates to a method for determining the theoretical rotational velocity (θmot) of an electric motor (E) that drives a vehicle's hydraulic pump (P) and whose rotational velocity is controlled according to the vehicle's speed (VS). At least three control variables are proportional to the following measuring variables a) the vehicle's steer angle speed (HS) b) the hydraulic pump's (p) stand-by rotational velocity (θstandby) c) the electrical motor's (E) input current (IMot).The control variables are multiplied by a value which decreases as the vehicle's velocity (VS) increases either before or after having been influenced by the associated transmission elements (f(HS), f(IMot), k). The invention is particularly applicable to a vehicle's steering system.

摘要： Provision of a power steering system capable of giving a driver no discomfort during high-speed travel. A controller calculates or stores a current instruction value I1 in accordance with a steering angle supplied from a steering angle sensor and a current instruction value I2 in accordance with a steering angular velocity; performs multiplication of the steering angle base current instruction value I1 and the steering angular velocity base current instruction value I2 by current instruction values I5, I6 set based on a vehicle speed, respectively; applies current instruction values I7, I8 in accordance with the vehicle speed serving as limit values to the corresponding steering angle base and steering angular velocity base current instruction values resulting from the multiplication; selects a larger value of the two current instruction values below the limit values; and determines the selected value as a solenoid current instruction value SI.

摘要： A fluid power assist rack and pinion steering system (12) for a vehicle having steerable wheels comprises a rack (66) connected with steering linkage of the vehicle for, upon movement of the rack, moving the steering linkage to effect turning of the steerable wheels. A rotatable pinion (64) is in meshing engagement with the rack (66). The steering system (12) also includes a control valve (22) comprising a valve core (40) rotatable relative to a valve sleeve (42). A first part (56) connects the valve sleeve (42) for rotation with the pinion (64). A mechanism (38) resists relative rotation between the valve core (40) and the valve sleeve (42) as vehicle speed increases by placing axial force on the valve sleeve. A second part (170) on the valve sleeve (42) resists axial movement of the valve sleeve relative to the valve core (40).
