摘要： In an automatic braking force control apparatus for a vehicle employing a deceleration feedback control system and an anti-skid control system executing, irrespective of a desired braking force for deceleration feedback control, an anti-skid cycle for preventing a wheel lock-up condition, the feedback control system calculates a desired braking force as a sum of a proportional-control signal component proportional to an error signal corresponding to a deviation from a desired deceleration, and an integral-control signal component corresponding to the integral of the error signal. The feedback control system memorizes the desired braking force, calculated just before an anti-skid cycle start time, as a memorized value, and initializes the desired braking force of an anti-skid cycle termination time to a predetermined value substantially corresponding to the memorized value for preventing a change in the desired deceleration occurring during the anti-skid cycle from being reflected in a feedback control signal.

摘要： A control unit of a continuously variable transmission computes a speed ratio command value based on a final target ratio, a time constant representing a predetermined dynamic characteristic and a time constant representing an estimated dynamic characteristic of the transmission so that a real speed ratio approaches the final target ratio according to a running state under the predetermined dynamic characteristic. A transient target ratio is computed based on the final target ratio and time constant representing the predetermined dynamic characteristic, a correction amount of the speed ratio command value is computed based on the difference between the transient target ratio and real speed ratio, and the transmission is controlled based on the speed ratio command value after correction by this correction amount. In this way, the difference between the transient target ratio and real speed ratio is reduced and a desired speed ratio response is obtained even when the operation of a speed ratio mechanism is limited and the real speed ratio has shifted from the transient target ratio.

摘要： A state-of-charge (SOC) estimating device and method for a secondary battery that estimates the SOC of the battery with high precision when variation takes place in the parameters of the battery model, even if the input current is constant. A first SOC estimating part estimates the open-circuit voltage by estimating the battery parameters en bloc using an adaptive digital filter computing treatment from the measurement values of the current and the terminal voltage and computes a first estimated SOC of the secondary battery from the open-circuit voltage and a predetermined relationship between the open-circuit voltage and the SOC. A second SOC estimating part computes a second estimated SOC by means of current-integration. State-of-charge estimated value-selecting part selects the second SOC value as when the current is constant and otherwise selects the first SOC value.
