摘要： In this system for vehicle roll control, a suspension device or an actuator is provided corresponding to each wheel of a vehicle, and resiliently suspends it from the vehicle body. Each such suspension device can alter its hardness or softness characteristics according to a control signal, while similarly the actuators are adapted to alter the suspended height of their wheels. A vehicle speed detecting device senses road speed, a steering angle detecting device senses steering angle, and a device detects the total vehicle body weight. A computing control device computes a predictive roll angle of the vehicle body from road speed and steering angle, and: if suspension devices are provided, controls them to be relatively hard when the absolute value of the predictive roll angle is larger than a threshold value, while controlling them to be relatively soft when the absolute value of the predictive roll angle is less than this threshold value; while, if actuators are provided, when the absolute value of the predictive roll angle is larger than a threshold value, it controls them in accordance with this predictive roll angle. Particularly, this computing device varies the threshold roll angle value according to the total vehicle body weight as detected by the weight detector, so as to decrease the threshold roll angle value along with increase of the total vehicle body weight.

摘要： In a vibration control apparatus, a physical value influencing characteristics of a suspension for supporting a vibrating body and a state value representing movement of the suspension are detected. A frequency distribution of these values with respect to levels is calculated every predetermined period of time. A target control force is calculated on the basis of the frequency distribution in consideration of a continuous change in external state. An actual control force (detection control force) is calculated by the detected physical value. The suspension characteristics are continuously, variably controlled so as to equivalently generate a control force corresponding to a difference between the target and detection control forces. As a result, the target control force is equivalently applied to the suspension, thereby damping the vibrations. The vibration control apparatus can generate an optimal target control force free from the influence of an external state change on the basis of the frequency distribution of the state and physical values of the suspension.

摘要： An apparatus for controlling steering of wheels of a vehicle comprises a control means, a driving means, and an actuator means. The control means comprises a feed forward signal operating means, a feed back signal operating means for generating signals for variables representing vehicle behaviors and output from a vehicle behavior sensor, and a control signal operating means for calculating a difference or sum of the signals output from the feed forwad and feedback signal operating means. The feed forward signal operating means comprises a steering angle signal circuit, a steering angular velocity signal operating circuit, a steering angle signal operating circuit having a first coefficient circuit for multiplying a steering angle signal with a coefficient, and an adder for adding the outputs from the steering angle signal circuit, the steering angle signal operating circuit, and the steering angular velocity operating circuit. A behavior correction capacity against a side wind or disturbance is very high, and a steering system can be controlled to shorten the response time for changes in vehicle behaviors with respect to a steering input, thereby providing optimal steering. The control means further comprises a gain changing means to supply optimal coefficients to the feed forward and feedback signal operating means.

摘要： An active suspension apparatus using hydropneumatic springs is disclosed to control damping characteristics in accordance with the vibration state of the passenger compartment of a vehicle during travel. An absolute acceleration of the floor of the passenger's compartment is detected and is compared with a reference value to discriminate the actual vibration state of the passenger compartment. The openings of restrictors arranged between hydropneumatic spring chambers and actuators are controlled in accordance with the discrimination result. In order to accurately detect the vibration state, specific vibration components are extracted by band-pass filters from the absolute acceleration signal.

摘要： The automotive tire being measured is loaded in advance by the load applying means, and the drum is driven to rotate the tire. A displacement of the rotatable shaft produced in response to a variation in the radial force acting between the tire and the drum is detected as a displacement of the movable member which is in turn indicated as the radial force variation generated on the tire. Thus, the apparatus can measure a radial force variation with precision under a condition approximating an actual running condition of automobiles.
