摘要： An electric damper which does not transmit unbalance wheel vibration to a vehicle body is provided. A low-pass cutoff frequency setting unit and a high-pass cutoff frequency setting unit respectively set the cutoff frequencies for band-stop filters to a frequency band corresponding to unbalance wheel vibration based on a signal indicating a vehicle speed from a vehicle speed sensor, and a function as a band-stop filter comprising a low-pass filter computation unit, a high-pass filter computation unit and an adder is computed for a displacement rate of the vertical motion of a wheel calculated by a differentiating unit in a damper control unit. A damper control amount computation unit calculates a control amount of controlling an electric motor for a motor-driven damper based on the calculated filtered displacement rate, and outputs a control signal to a motor driving unit through a driving circuit output unit.

摘要： A magnetostrictive torque sensor includes a magnetostrictive film of width W provided along a circumference of a rotational shaft. The film causes magnetostriction in correspondence to a torque applied to the rotational shaft. The torque sensor also includes excitation and detection cores each having substantially U-shaped configuration. These cores are disposed in opposed relation to the film. The excitation core extends through an excitation coil while the detection core extends through a detection coil. The excitation core is disposed on the detection core at right angles. The film has a magnetic path passing therethrough. The magnetic path, the excitation coil, and the detection coil cooperate with each other to provide a magnetic circuit. The excitation coil and the detection coil provides a bridge circuit in cooperation with each other. When a torque is applied to the rotational shaft, the film causes magnetostriction in correspondence to the torque. The magnetostriction is electrically detected by the bridge circuit.

摘要： An electric power steering apparatus transmits an auxiliary torque from an electric motor to a steering system via a mechanical clutch composed of a plurality of sets of friction clutch mechanisms. At least one of the plural clutch mechanism sets is disengageable in advance to the remaining clutch mechanism set. This means that only a part of the clutch mechanisms can be brought to the disengaged state at an advanced timing. When the selected part of the clutch mechanisms is disengaged, the remaining clutch mechanisms are subjected to an unbalanced force tending to disengage the remaining clutch mechanisms. By the effect of the unbalance force, frictional forces acting in the remaining clutch mechanisms are considerably reduced, so that the remaining clutch mechanisms can be disengaged by a small clutch-disengaging force. Thus, the mechanical clutch as a whole can be disengaged by a smaller manual effort or force than as required when all the clutch mechanisms are disengaged at one time.
摘要翻译：电动助力转向装置通过由多组摩擦离合器机构组成的机械离合器将辅助转矩从电动机传递到转向系统。多个离合器机构组中的至少一个预先脱离剩余的离合器机构。这意味着只有一部分离合器机构可以在高级时机处于脱离状态。当离合器机构的选定部分脱离时，剩余的离合器机构受到不平衡的力，以使剩余的离合器机构脱离。通过不平衡力的作用，作用在其余离合器机构中的摩擦力大大降低，使得剩下的离合器机构可以通过小的离合器分离力而脱离。因此，当所有离合器机构一次脱离时，机械离合器作为整体可以通过比所需的更小的手动力或力分离。

摘要： In an electric power steering device of the type wherein an input member connected to an electric motor and an output shaft including an output member connected to a steering wheel are connected via a plurality of sets of friction clutch mechanisms for transmitting an auxiliary torque from the electric motor to the output shaft, the output member is displaceable in a radial direction relative to the input member. In response to rotation of position control members of the friction clutch mechanisms, one of the friction clutch mechanisms sets is disengaged whereupon a force or pressure exerted from the locking members of the other friction clutch mechanism sets to the output member forces the output member to move in the radial direction relative to the input member. With this movement of the output member, a frictional engagement force acting between the locking members and the input and output members is reduced. Thus, the friction clutch mechanisms can be readily disengaged by a force which is much smaller than the force required to disengage all the friction clutch mechanisms at one time.
