摘要： Vehicular acceleration is sensed and used to set and/or modify at least two of a plurality of control sensitivity values in a manner which increases one with respect to the other and thus avoids the situation wherein a limited amount of servo power is wasted by futile operation of a servo powered arrangement which cannot produce a large control effect under the instant operating conditions and enables an adequate amount servo power to be directed to the operation of a different arrangement which can be effective.

摘要： A damping device is installed between a vehicle body and desired two of wheels and provided with a damping force producing mechanism for producing a larger damping force when the two wheels make strokes involving a relative movement therebetween, such as at the time of rolling, pitching, etc. than when the two wheels make strokes without involving any substantial relative movement therebetween, such as at the time of bouncing. In one embodiment, the damping force producing mechanism comprises a pair of restrictions in communication with cross conduits interconnecting upper and lower cylinder chambers. The conduits and cylinder chambers are arranged so as to cause a larger flow rate of fluid to pass through the restrictions when the wheel strokes involve a relative movement between the wheels than when the wheel strokes does not involve such relative movement.

摘要： Disclosed is a split engine control system wherein the intake manifold is segmented by a shut-off valve into a first chamber portion leading to a first group of cylinders and a second chamber portion leading to a second group of cylinders. During periods of relatively low load, the cylinders of the second group are deactivated and the shut-off valve is closed to isolate the second chamber from the first chamber to cut off air supply to the deactivated cylinders. Exhaust gases are recirculated through the deactivated cylinders so that their pumping loss is minimized. A pressure detector is provided to detect a pressure difference which might develop between the first and second chambers during the partial cylinder operation to control the flow rate of the recirculated gases until the pressure difference reduces substantially to zero.

摘要： A suspension control system for automotive vehicles automatically adjusts the damping strength of variable shock absorbers or other dampers in accordance with road surface conditions as recognized by frequency analysis of a vehicle height or vibration sensor signal. The sensor signal reflects vertical displacement of the vehicle body from the road surface and includes high-frequency components due solely to displacement of the wheels or unsprung mass relative to the road surface and low-frequency components due to displacement of the vehicle body or sprung mass. The sensor signal is filtered into these separate frequency bands, the amplitude of each of which is compared to a corresponding reference level. The results of comparison give an indication of the degree and scale of irregularities in the road surface; specifically, a high-amplitude low-frequency component indicates larger-scale bumps and dips capable of bouncing the vehicle whereas a strong high-frequency component reflects a rough-textured road surface, such as gravel. The comparison information is sent to a suspension system controller which causes actuation of the shock absorbers to a stiffer mode of operation when the low-frequency sensor signal components are relatively strong.
