A suspension control system for an automotive vehicle is provided in which a movement of a sprung mass velocity is monitored, when the magnitude of the sprung mass velocity is below a predetermined threshold value, a control unit outputs a control signal to a pulse motor to vary the position of an adjuster so that one of extension and compression stroke sides of a position member of a shock absorber, whose direction is the same as that of the sprung mass velocity provides a high damping coefficient, and when the magnitude of the sprung mass velocity is above the predetermined threshold value, a control constant for the damping coefficient is changed toward a high damping sensitivity range until the sprung mass velocity exceeding the predetermined threshold value is reduced below another predetermined threshold value, a magnitude of the other predetermined threshold value being lower than that of the predetermined threshold value.

摘要:
A time-division multiplex radio transmission apparatus includes a first frequency divider, a logic processing unit, a digital filter, a modulation unit, a high-frequency amplification unit, and a second frequency divider. The first frequency divider frequency-divides an input clock signal to output a first frequency-divided clock signal. The logic processing unit performs logic processing of an input data signal on the basis of the first frequency-divided clock signal and outputs a burst timing signal. The digital filter is reset in response to the burst timing signal and converts output data from the logic processing unit into a modulation baseband signal on the basis of the input clock signal. The modulation unit modulates an output signal from the digital filter. The high-frequency amplification unit performs burst-waveform processing of an output signal from the modulation unit for each time slot for time-division transmission on the basis of the burst timing signal. The second frequency divider outputs a second frequency-divided clock signal obtained by frequency-dividing the input clock signal to reset the first frequency divider.
摘要:
In a vehicular suspension a vertical acceleration of a sprung mass of a vehicular body and a relative speed between the sprung mass and an unsprung mass (viz., a wheel assembly) are detected. A sprung mass vibrating frequency is derived on the basis of detected vertical accelleration and relative speed, and a control unit determines whether the derived sprung mass vibrating frequency is equal to or higher than a predetermined dead frequency or not. The control unit outputs a control signal to the damper to change the damping force coefficient on the basis of the determination of whether the derived sprung mass vibrating frequency is equal to or higher than a predetermined dead frequency or not.
摘要:
The damping coefficient of a shock absorber of a suspension unit for a vehicle body of an automobile is varied in accordance with a vertical speed of the vehicle body such that it is normally varied in proportion to said vertical speed indicative signal however, from the time the vertical speed satisfies a predetermined relationship with a threshold level the largest damping coefficient is established and maintained and until the vertical speed reaches a peak.
