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.

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 target speed change ratio of a continuously variable transmission of a vehicle is set according to the running state of the vehicle. Dynamic characteristics of the continuously variable transmission are estimated for each speed change ratio, and a speed change ratio output value is calculated based on the dynamic characteristics. An external disturbance compensating value is computed from a speed change ratio command value, the real speed change ratio, the dynamic characteristic estimated value and a predetermined time constant, and the transmission is controlled by the speed change ratio command value based on the speed change ratio output value and external disturbance compensating value. By applying the lesser of a temporary target speed change ratio having predetermined characteristics and the target speed change ratio to the calculation of the speed change ratio output value when the vehicle speed is equal to or greater than a predetermined value, a dimensional error in parts is compensated and smooth speed change control is realized when the vehicle starts.

摘要： A speed change ratio of a continuously variable transmission comprising a V-belt looped around a pair of variable pulleys for varying the speed change ratio according to a first and second oil pressures. A speed change control valve converts a first oil pressure from an oil pressure supply unit to a second oil pressure based on a speed change ratio command value. The speed change ratio command value is calculated by a microprocessor according to a real speed change ratio and dynamic characteristics of the transmission. By calculating the dynamic characteristics according to the real speed change ratio and the first oil pressure, a set response of the transmission is always obtained regardless of fluctuations of the first oil pressure.

摘要： When there is a requirement on switching from the electrically driven drive mode to the hybrid drive mode by changing an accelerator position opening, the torque capacity is generated for the first clutch to start the engine. However, as torque capacity is at β1, the engine rotational speed is quickly increased to the high-speed region free of the influence of the compressive reactive force of the engine; once the engine rotational speed becomes the high-speed region, the engine rotational speed is decreased as torque capacity and is at β2. Consequently, it is possible to quickly pass through the low engine rotational speed region as the engine rotational speed torque is increased under the influence of the compressive reactive force, and avoiding the poor acceleration, as can be seen from the smooth variation of the time sequence increase of the transmission output rotational speed as indicated by β3, is possible.

摘要： Provided is an electrically driven vehicle, wherein unexpected vibration or shock is prevented during interruption of torque transmission. An electric vehicle having an electric motor as its power source is provided with an F/F calculation or operation unit, an F/B calculation or operation unit, an adder, model determination units, and target torque value switching units. The F/F calculation unit calculates a first target torque value by F/F operation. The F/B calculation unit calculates a second target torque value by F/B operation using a model. The adder adds the first target torque value and the second target torque value, to obtain a motor torque command value. The model determination units evaluate whether or not an interruption in the torque transmission to drive shafts occurs. The target torque value switching units stop the F/F- and F/B operations while torque transmission interruption is confirmed.
