摘要： Fuel economy of a multi-cylinder internal combustion engine has been improved by allowing, when a vehicle is at a standstill, the engine to run on selected cylinders of all. The idling operation of the engine on the selected cylinders has been made smooth by the provision of a switch valve in a control circuit of the transmission. With the switch valve, as soon as an accelerator pedal is released when the vehicle is at a standstill, hydraulic fluid will be drained from the control circuit to render a gearing of the transmission in a neutral condition even if a manually selector valve in the control circuit is held in a drive range position. This prevents transmission of load to the engine through the hydrokinetic unit which otherwise would occur when the manually selector valve is in the drive range position.

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： A suspension control system for an automotive vehicle 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 and the amplitude of each is compared to a corresponding reference level to give an indication of the irregularities in the road surface. Specifically, a high-amplitude low-frequency component indicates large-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 hard mode of operation when the low-frequency sensor signal components are relatively strong.

摘要： A suspension control system has a manual operator which is manually accessible is provided for adjusting suspension control characteristics depending upon the driver's tastes or depending upon the vehicle condition. The adjustment of the suspension control characteristics can take place with respect to each of a plurality of suspension control items, such as roll-suppressive suspension control, anti-dive suspension control, anti-scout suspension control, road roughness dependent suspension control, bottoming control and so forth. By allowing adjustment of the suspension control characteristics with respect to each control item independently of that with respect to other control items, the suspension control characteristics of the overall suspension control system can be precisely fit the driver's feeling and/or precisely adapted to the vehicle condition.

摘要： A suspension control system can precisely control the damping characteristics of vehicular suspension for successfully and satisfactorily providing anti-dive and anti-rebound feature. The suspension control system is adapted to detect vehicle deceleration on the basis of a variation of a vehicle speed and to compare the vehicle speed with a predetermined vehicle speed criteria across which damping characteristics of the vehicular suspension vary between a harder suspension mode and a softer suspension mode. The vehicle speed criteria is variable depending upon vehicle deceleration so that the criteria becomes higher when the magnitude of deceleration is greater than a predetermined level. By hardening the suspension at an earlier timing during relatively abrupt deceleration of the vehicle, the magnitude of nose dive is reduced and the magnitude of rebounding motion after nose-dive can be reduced. This assures riding comfort by reducing the magnitude of pitching behavior of the vehicle front end. On the other hand, by providing later timing for hardening the suspension while deceleration of the vehicle is relatively low, softer damping characteristics can be maintained for a longer period to assure riding comfort by successfully absorbing bounding and rebounding shock from the road surface.
