摘要： In an electric power steering apparatus, a phase control characteristic for a signal corresponding to detected steering torque is changed according to the judgment whether the steering is in a return steering state or a feed steering state, so that a response of a variation of target output value of a motor for generating steering assist power to a variation of the detected steering torque decreases in the return steering state in comparison with that in the feed steering state. An output control characteristic of the motor is changed according to the judgment synchronously with the change of the phase control characteristic, so that a response of a variation of the output command value to a variation of deviation between the target output value and actual output value decreases in the return steering state in comparison with that in the feed steering state.

摘要： An apparatus (10) for turning steerable wheels (12, 14) of a vehicle in response to turning of a steering wheel (18) of the vehicle. The apparatus includes a hydraulic power steering gear, which does not include a rotary valve responsive to a steering input generated by turning of a steering wheel (18). The hydraulic steering gear includes a first chamber (96) for holding hydraulic fluid and a second chamber (98) for holding hydraulic fluid. An increase in fluid pressure in one chamber acts to turn the steerable wheels (12, 14) of the vehicle in one direction and an increase in fluid pressure in the other chamber acts to turn the steerable wheels (12, 14) in a direction opposite the one direction. The apparatus (10) includes a variable flow mechanism (50) for supplying a flow of hydraulic fluid to the first and second chambers (96, 98), which flow varies in dependence upon at least one sensed vehicle condition.

摘要： The controller in an electric power steering apparatus stores the relationship between the steering torque and the basic assist torque in which the relationship is stored as assist characteristic, and stores the relationship between the steering angle correspondence value corresponding to the steering angle of the vehicle and the motor output correction value in which the relationship is stored as correction characteristic. The controller corrects the output of the motor, which is required in order to generate the basic assist torque, in accordance with the motor output correction value determined from the steering angle correspondence value and correction characteristic, in which the basic assist torque is determined from the steering torque and assist characteristic. The correction characteristic is set so that the denominator in the frequency transfer function (K1θp+K2θps+K3θps2)/(s2/ω02+2ζ0s/ω0+1) of the motor output correction value to the steering angle correspondence value has a term which includes the resonance angular frequency of the yaw motion of the vehicle, and a term which includes the damping ratio of the yaw motion of the vehicle.

摘要： In an electric power steering apparatus, a steering torque is detected by a torque sensor, and a motor which generates steering assist power is controlled so that steering assist power is generated in accordance with basic assist torque which corresponds to the detected steering torque. The phase of the output signal of the torque sensor is caused to vary by a phase control element. The phase control characteristic of the phase control element is altered in accordance with the judgment results of a steering state judgment element as to whether the steering state is a return steering state or positive steering state, so that, in the frequency response characteristic of the output to input of the torque sensor, the gain at the higher frequency band where the frequency is greater than a set value is reduced in the return steering state in comparison to the positive steering state.

摘要： An electrically driven power steering apparatus is structured such that a large impact on a rack shaft (22) occurs upon an impingement of a steering stopper, and, even when an axial force acting on a ball bearing (25) of a presser member (30) becomes zero, a rotation of the presser member (30) is hindered by caulking c at a thin plate member (30b). Therefore, the presser member (30) does not slacken, and a predetermined axial force can be given again to the ball bearing (25) when the impact dissipates. The thus structured power steering apparatus exhibiting, though the cost is low, an excellent shockproof characteristic and capable of preventing the bearing from coming off a ball screw nut, can be provided.

摘要： An electric power assisted steering system is disclosed in which a torque demand signal (8) is generated and applied to an electric motor (1) operatively connected to a steering mechanism (5) in order to assist a driver of the vehicle when steering the vehicle. The torque demand signal (8) includes a damping component that is dependent upon a measurement of torque T carried by the steering mechanism and a measurement of the angular velocity &ohgr; of the steering mechanism. The torque produced by the motor (1) is not obtrusive during “hands-on” maneuvers but provides enhanced damping in other maneuvers such as a steering flick.

摘要： An electric power steering apparatus having a steering system capable of flexibly setting a relationship between a steering angle of a steering wheel and a wheel angle of a tire. The first motor controls steering reaction force exerted on the steering wheel. The on-center region determination section determines whether the steering wheel is in a position of an on-center region. The tire reaction force torque detection section detects tire reaction force torque transferred from the tire. The control section calculates a steering torque based on the tire reaction force torque and a torque gain. This torque is detected by the tire reaction force torque detection section. And the control section controls the first motor to exert the steering reaction force corresponding to the above calculated steering torque on the steering wheel. This control section also sets the torque gain in case of determining of on-center region larger than that in case of determining of non-on-center region.
