    摘要: The present invention relates to a method for estimating vehicle speeds independently on front and rear wheels of a four-wheel motor vehicle on the basis of front wheel speeds and rear wheel speeds, for use as a basis for determining slip rates for front and rear wheels. According to the first method of the invention, a reference wheel speed determined by the vehicle speed as estimated from the left and right wheel speeds cannot be unnecessarily increased during turning of the vehicle. According to the second and third methods of the invention, the estimated vehicle speed largely does not deviate from the actual vehicle speed in the event of a phase difference of variants produced between the left and right wheels due to an anti-lock control during the turning of the vehicle. According to other features of the invention, corrections can be performed with respect to the inner and outer wheel differences during turning of the vehicle based on an index representative of the traveling speed, lateral acceleration of the vehicle and steering angle.

    摘要: During the acceleration of an elevator car frequency modulated clock pulses are counted up by a first counter to generate a command speed pattern. A second counter similarly generates a second speed pattern identical in shape to and delayed a predetermined time relative to the command speed pattern. A randum access memory successively stores theoretical distances of movement of the car due to the command speed pattern suitably corrected and the second speed pattern as a distance-to-speed function. When and after both patterns first equal each other, a command deceleration pattern is generated to follow objectives or the distance-to-speed function. Once the command speed again equalled the objective, the intact distance-to-speed function is used as a command deceleration pattern concerning residual distances to a stop floor.

    摘要: Embodiments of the invention provide an interface circuit that is capable of reducing the power consumption, which may be increased by a shoot-through current, and provide an electronic device having such an interface circuit. In one embodiment, an interface circuit exchanges signals with another electronic device via a signal transmission line. The interface circuit includes a switch for pulling up the signal transmission line and a switch for pulling down the signal transmission line. While a pull-up or pull-down is performed, the interface circuit detects the potential level of the signal transmission line to determine whether the signal transmission line is pulled down or pulled up by the other electronic device. If the signal transmission line is not pulled down/pulled up by the other electronic device, the interface circuit exercises pull-down/pull-up control.

    摘要: During the acceleration of an elevator car a command acceleration pattern in the form of frequency modulated clock pulses is counted by a first and a second counter. The first counter issues a command speed pattern. The speed pattern is integrated to calculate the distances of movement of the care which is successively stored in a random access memory at addresses determined by the speeds from the second counter, at equal increments of speed. During the deceleration the distances of movement succesively read out from the memory are compared with the residual distances to the stop floor and the second counter counts the results of the comparison down to produce an ideal speed curve. The curve supplied to the memory is also compared with the actual car speed to modify the command acceleration with the result that the actual speed follows up the ideal speed curve.

    摘要: A position sensor disposed on an elevator car has a first rotatable shaft connected to a secondary winding of a transformer or a switch actuating member, and a second rotatable shaft coaxial with the first shaft and connected to a primary transformer winding or to a switch position changing member. A first roller engages a rod-shaped cam mounted at an angle to a guide rail for the car toward the end of the path of travel of the car to rotate the first shaft in a direction to decrease the voltage across the secondary winding or successively actuate the switches. If the car moves horizontally, the first shaft is rotated to change the voltage and a second roller engaging the rail rotates a second shaft to compensate for this change in voltage.
