摘要： In a power steering system comprising a power cylinder for assisting a steering power of a steering mechanism, a hydraulic pump for supplying a hydraulic pressure to the power cylinder, a first oil passage and a second oil passage connecting the power cylinder and the hydraulic pump respectively, a motor for driving the hydraulic pump, and power steering control means for calculating a command value to the motor based on the steering torque, a flow rate of the working oil supplied from a high-pressure side oil passage to a low-pressure side oil passage is restrained at the transition from the end of the steering state (lock end) of the steering mechanism to the returning. The flow-rate restraint increasingly corrects a driving current of the motor in the steering direction or limits the flow rate of the working oil.

Under the second condition, the second directional control valve intercommunicates the reservoir and the second-pressure-line downstream passage section, and blocks fluid communication of the second-pressure-line upstream and downstream passage sections. Under the first condition, the second directional control valve intercommunicates the second-pressure-line upstream and downstream passage sections.

摘要： A suspension control apparatus for use with shock absorbers provided between sprung and unsprung masses of the vehicle at the respective road wheel positions for providing variable damping force characteristics. A control unit receives first sensor signals indicative of sensed vehicle sprung mass vertical behaviors for controlling the shock absorbers to have respective target damping force characteristics determined based on the vehicle sprung mass vertical behaviors. A surface condition of a road on which the vehicle is running is determined based on the first sensor signals. The control unit also receives a second sensor signal indicative of a sensed vehicle lateral acceleration for detecting vehicle steering operation. The second sensor signal is compared with a reference value. Vehicle steering operation is detected in response to a result of comparison of the second sensor signal with the reference value. The target damping force characteristics for vehicle steering operation are determined upon the detection of the vehicle steering operation. The reference value is corrected based on the determined surface condition.

摘要： An apparatus and method for controlling damping force characteristics of respective vehicular shock absorbers in which vehicular vertical behavior(s) at the position(s) of the vehicular body which are forward by a predetermined distance from a tread of rear left and right road wheels are determined, the positions including front left and right road wheel sides, and corresponding vertical behavior signals are derived. Control signals for front left and right and rear left and right road wheel side shock absorbers are formed on the basis of respective processed signals having frequency-dependent characteristics formed from the vehicular behavior signal(s). The damping force characteristics of front left and right road wheel side shock absorbers are controlled on the basis of the control signals formed on the basis of the processed signal based on the front left and right road wheel vehicular behavior signals. Those of rear left and right road wheel side shock absorbers are controlled on the basis of the control signals formed on the basis of the processed signals based on the front position vehicular vertical behavior signal at the position forward from the tread between the rear left and right road wheels. The phases of the control signals V are generally matched with vehicular behavior velocity signals which would actually be generated at rear road wheel arranged positions of the vehicle.
