摘要： A suspension control system for use with shock absorbers provided between sprung and unsprung masses of an automotive vehicle at the positions of the respective vehicle road wheels for providing variable damping force characteristics. Sprung mass vertical velocities at the respective road wheel positions are derived from a sensed sprung mass vertical behavior. Relative velocities between the sprung and unsprung masses at the respective road wheel positions are derived from the sensed sprung mass vertical behavior with the use of a predetermined transfer function including terms related to damping coefficients of the respective shock absorbers. A control unit is provided for producing control signals based on the derived sprung mass vertical velocities and the derived relative velocities to control the damping force characteristics of the respective shock absorbers. Damping coefficients of the respective shock absorbers are determined based on the corresponding control signals. The terms related to the damping coefficients of the respective shock absorbers are varied according to the determined damping coefficients.

摘要： A method and apparatus detects degradation in performance of an engine by comparing signals such as those obtained from magnetostrictive sensors which are related to, but not necessarily accurately correlated with, stress/strain states of a torque/load transmitting member. A first signal is obtained relating to the stress in the member produced by a first loading event or series of events, typically from the firings of a cylinder in an internal combustion engine. A second signal is obtained which relates to the stress in the member produced by a second loading event or series of events from the same or other cylinder in which the torque/load was intentionally inhibited. The first and second signals are then compared to detect degradation in output of the engine.

摘要： A suspension control system of the present invention varies a damping force according to a velocity ratio of a mass-body velocity to a relative velocity, while ensuring both a comfortable drive and stable cruising. In the suspension control system, a CPU calculates a mass-body velocity Zd and a relative velocity Yd based on detection signals from sensors and determines a velocity ratio Zd/Yd (steps S110 and S120). A small skyhook damping coefficient is set for a small vehicle speed V to reduce a damping force according to the velocity ratio Zd/Yd (step S130). In the process of varying the damping force, a stepping motor used for the variation in damping force is driven at a low driving frequency for a small vehicle speed V (step S180). While the vehicle runs at a relatively low speed, the suspension control system of the invention restricts the degree of variation in damping force and lowers the rate of variation in damping force, thereby relieving shocks or uncomfortableness due to a delayed control of damping force, which is caused by a delayed detection of the relative velocity or a delayed response of devices and substantially maintaining a drive.

摘要： A method and apparatus to detect variations in load by comparing signals related to, but not necessarily accurately correlated with, stress/strain states of a load transmitting member. In one embodiment, a first signal is obtained relating to the time rate of change of stress in the member produced by a first loading event or series of events. A second signal is obtained which relates to the time rate of change of stress in the member produced by a second loading event or series of events. The first and second signals are compared to detect significant variations in loading. Each of the two signals may be a composite of other signals. A magnetostrictive sensor may preferably be used to obtain the signals relating to the stress in the load transmitting member. The load may be applied force, torque, stress, strain, or deflection. In another embodiment, the time rate of change of a single segment of an analog signal related to, but not directly correlated with, stress is used to determine rapid changes in load. In yet another embodiment, a statistical value derived from a plurality of signals is used to determine variation in load. Applications comprise internal combustion engine and driveline torque variation diagnostics, brake pedals, and suspension systems.

摘要： A suspension control system for an automotive vehicle is provided which is operable to control transmission of vibratory energy from a road surface to a vehicle body. This suspension control system includes a variable damping force shock absorber, a vertical speed sensor which detects vertical speed of the vehicle body, a relative displacement speed sensor which detects the relative displacement between the vehicle body and a road wheel, and a damping force control unit which is operable to modify a damping force of the variable damping force shock absorber over a range from preselected maximum to minimum values based on the vertical speed and the relative displacement speed. When the vertical speed and the relative displacement speed are smaller than preselected first and second threshold values respectively during vibratory motion of the vehicle body wherein the vertical speed and the relative displacement speed are in the same phase, the damping force control unit controls the variable damping force shock absorber to produce the damping force of a level smaller than the maximum value by a preselected value.
