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 order to realize cost reduction in a gear pump apparatus by reducing form accuracy of a gear while securing pump performance, a running-in coating is provided on a tooth sliding contact portion when forming a confinement area in at least one of gears of the gear pump apparatus. By this feature, the running-in coating is gradually worn away and deformed according to rotary drive of the pump, and thus it is possible to obtain an optimal gear form in meshing combinations of the gears. Further, it is possible to reduce leakage inside the pump to secure the pump performance even if the form accuracy of the gear is reduced for the sake of the cost reduction.

摘要： A suspension control system for an automotive vehicle is provided. This suspension control system comprises variable damping force shock absorbers and a control unit which controls the shock absorbers to assume damping force characteristics in a range between preselected higher and lower damping coefficients. The control unit is operable to provide a control parameter indicative of bouncing motion of a vehicle body based on sprung vertical speed to determine a damping coefficient against the bouncing motion. When the control parameter is greater than a threshold value, the damping coefficient is modified to a lower value, while when the control parameter is less than the threshold value, the damping coefficient is modified to a higher value. With this damping coefficient modification, the bouncing motion is suppressed effectively while assuring passenger comfort.
