    摘要: A telescopic actuator is adapted to be used on a right side or a left side of a body. The telescopic actuator includes a housing having a cylindrical shape and formed with an opening portion, an output rod supported inside the housing so as to be protrudable and retractable with respect to the housing, and a stroke sensor comprising a detectable portion provided on the output rod so as to be movable inside the opening portion of the housing and a detecting portion provided on the housing so as to face the detectable portion. A direction in which the detectable portion is eccentrically disposed with respect to a vertical plane including an axial line of the output rod is different depending on whether the telescopic actuator is used on the right side or on the left side of the body.

    摘要: A steering controller for an electric power steering device 110 includes a base signal computing part 51 for computing a base signal DT in accordance with at least the steering torque; a damper compensation signal computing part 52 for computing a damper compensation signal in accordance with an angular velocity of an electric motor 4 or a speed of steering wheel turn; and an inertia compensation signal computing part 53 for compensating inertia and viscosity in the steering unit. The electric motor is driven by a target signal IM1 obtained by compensating the base signal with a damper compensation signal and an inertia compensation signal, to provide a steering auxiliary force. The target signal of the auxiliary torque is compensated so that a difference between a reference self-aligning torque of front wheel in a front wheel steering vehicle and a self-aligning torque of front wheel in an all-wheel steering vehicle is provided to a driver as a responsive feeling from the steering torque.

    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: A power spectrum estimation unit (200) obtains an estimated sound power spectrum Ps(ω), based on a power spectrum P1(ω) and on a first calculated value obtained by at least multiplying a power spectrum P2(ω) by a weight coefficient A2(ω). A coefficient update unit (300) updates the weight coefficient A2(ω) and a weight coefficient A1(ω) so that a second calculated value approximates to the power spectrum P1(ω).

    摘要: An electric power steering apparatus comprising a rack shaft having two racks, a first rack-and-pinion mechanism for transferring a steering torque to the rack shaft, and a second rack-and-pinion mechanism for transferring an assist torque to the rack shaft. The second rack-and-pinion mechanism includes a pinion and a rack both being helical gears so that a large torque can be transmitted to the rack shaft. Teeth of the pinion and rack are arc profiled. The arc profiled teeth mesh with each other through a large contact area of concave and convex surfaces thereof and hence with a reduced contact pressure compared to involute profiled teeth. The arc profiled teeth thus have increased surface fatigue strength, bending strength and bending fatigue strength and can transmit an assist torque sufficiently to the rack shaft. Moreover, they have durability sufficient to withstand a torque load of a motor inertia.
