Abstract: A variable damping force shock absorber control system for an automotive vehicle is provided. This control system includes a variable damping force shock absorber adapted to have a plurality of damping modes of operation each assuming different damping characteristics, a vertical acceleration sensor for detecting vertical acceleration acting on a vehicle body, and a control unit. The control unit mathematically determines vertical speed of the vehicle body based on the vertical acceleration to select one of the damping modes based on the vertical speed, and determines the amount of damping force in each damping mode according to a vibratory condition indicative parameter which is varied as a function of a variation in amplitude of the vertical acceleration.

Abstract: A method and apparatus for dynamically leveling the attitude of a vehicle using a low power fully active suspension system. The suspension system includes a hydraulic actuator operably connected at each corner of the vehicle between sprung and unsprung portions thereof, sensors for detecting movement of the sprung and unsprung portions of the motor vehicle and for deriving a force signal for each actuator in response thereto, and a valving arrangement for causing the hydraulic actuator to generate a desired output force in response to the force signal. The valving arrangement has a first valving that is operable for generating the output force by selectively varying the damping characteristics of the hydraulic actuator when the force signal is within a predetermined range. The valving arrangement also includes second valving for selectively controlling the supply and discharge of hydraulic fluid between the hydraulic actuator and a fluid pressure source for generating the output force when the force signal is outside of the predetermined range. Thus, the lower power fully active suspension system is adapted to produce the desired output force through selective actuation of the first and second valvings for limiting the duty cycle and power requirements of the fluid pressure source.

Abstract: A device for detecting the condition of the surface and adjacent edges of a road by means of electromagnetic radiation. A transmitter emits measuring beam pulses of electromagnetic radiation directed in a linear area of the road. Back scattered radiation from reflection of the measuring beam pulses by features of the road surface and adjacent areas are received and transformed into a time sequence signal. A signal processing and analysis unit analyzes the time sequence signal to identify features and surfaces of the road and their distance from the vehicle.

Abstract: A suspension apparatus of a vehicle has a cylinder unit interposed between a sprang weight and an unsprung weight, which changes a ride height of the vehicle body by supplying or discharging an operating liquid through a supply/discharge control valve. The supply/discharge control valve is controlled on the basis of a predetermined condition so as to control a posture of the vehicle body. There are further provided a rebound detecting means for detecting a rebound of each of the wheels and a pressure detecting means for detecting a pressure in the cylinder unit. When the rebound is detected by the rebound detecting sensor to be above a given value, if the pressure detected by the pressure detecting means is continued at a magnitude above a given value for a given period of time, it is judged that the supply/discharge control valve is in trouble.
