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.

摘要： In vehicular steering control apparatus and method, a carrier frequency of a PWM control signal to drive an electric motor on a basis of the manipulated variable of the electric motor is controlled and the carrier frequency is set to at least two predetermined set frequencies in accordance with at least one of a driving state of the electric motor and a traveling state of the vehicle, one of the predetermined set frequencies being set to reduce noises in the inverter and the other of the predetermined set frequencies being set to reduce a switching loss in the inverter. For example, the carrier frequency is set to be lowered to the other of the predetermined set frequencies in a case where a rotational speed of the electric motor is driven in a rotational speed region (A2) higher than that in a constant torque region (A1).

摘要： In an apparatus for variably controlling valve timing of engine by generating, between a crankshaft and a cam shaft, a phase difference which periodically varies in a manner synchronized with a rotational phase of the cam shaft: actual phase differences are obtained at two discrete rotational phases of the cam shaft, respectively; there is assumingly calculated an amount of deviation (phase deviation .theta.) of phase difference relative to the rotational phase of the cam shaft; and the phase difference is feedback controlled based on that value of the detected phase difference which is corrected in accordance with the amount of deviation (phase deviation .theta.).
