摘要： In hydraulic control, an electronic control unit controls controlled hydraulic pressure of a control valve in order to control a hydraulic oil amount in a torque converter and a hydraulic oil pressure of a forward-reverse travel switching mechanism, and the electronic control unit increases the controlled hydraulic pressure when the hydraulic oil amount in the torque converter is insufficient at an engine start or immediately after the engine start in comparison with a case where the hydraulic oil amount in the torque converter is sufficient. The hydraulic control device includes: the torque converter; the forward-reverse travel switching mechanism; the control valve configured to change the hydraulic oil amount in the torque converter and the hydraulic oil pressure of the forward-reverse travel switching mechanism by changing the single controlled hydraulic pressure; and electronic control unit.

摘要： A transmission ECU 12 determines whether or not the conditions for executing a neutral control operation are satisfied (step S11), and measures hydraulic oil temperature if it determines that the execution conditions are satisfied (step S12). Then, the transmission ECU 12 sets a target speed ratio for a torque converter 3 corresponding to the measured hydraulic oil temperature (step S13), and performs a neutral control operation to bring the speed ratio of the torque converter 3 equal to the target speed ratio (step S14).

摘要： A power transmitting apparatus for a vehicle mounted with a torque converter and an idle-stop mechanism can be configured to improve fuel economy without cancelling a fuel-cut-ff during vehicle speed reduction and to reduce the manufacturing cost by eliminating an electrically-driven oil pump. A power transmitting apparatus can comprise a torque converter, a clutch mechanism, an oil pump, a continuously variable transmission, a clutch control device, an engine control device, and a flow control device. The flow control device can be configured to limit or prevent the supply of oil to the torque converter by the oil pump and to prioritize the supply of oil to the clutch mechanism and the continuously variable transmission when the vehicle speed is reduced below a predetermined value with fuel being cut off by the engine control device during vehicle speed reduction.

摘要： The temperature of a machine component is controlled by transferring heat generated by a torque converter under restricted conditions to the component. The machine includes a circulating fluid system configured to transfer heat from the torque converter to the remotely positioned machine component. A controller is configured to sense the temperature of the component, and to restrict motion of the torque converter turbine when the sensed temperature is below a desired temperature. Heat generated by the torque converter under the restricted condition is transferred through the circulating fluid system to the remote component, such as the machine power source, to control the temperature thereof.

摘要： A system for calibrating a transmission includes a slip generation module, a volume determination module, and a calibration control module. The slip generation module generates transmission slip. The volume determination module, after the transmission slip has been generated, applies a torque converter clutch (TCC) and determines a volume of the TCC based on a period for the TCC to fill with hydraulic fluid. The calibration control module generates a calibrated volume based on the determined volume and calibrates a control module based on the calibrated volume, wherein the control module controls the transmission.

摘要： In a property correcting system of an automatic transmission according to the present invention, a difference of revolutions between input revolutions Nin of a torque converter and turbine revolutions Nt is compared with target rotational difference ΔN, and is increased/reduced by the feedback operation (S6 and S7). It is checked to see if the difference of revolutions is converged to the target rotational difference ΔN (S8). When a driving duty duty which is converged to the target rotational difference ΔN is within a shipping determining standard, the value is stored (S10). A differential value between the stored driving duties duty of the respective automatic transmissions and the reference value is written to a TCU, as the amount of correction of the respective automatic transmissions, thereby correcting the variation in properties of the individual automatic transmissions, starting from the initial shipping timing. A preferable shift quality is obtained without prompting the learning based on the actual driving.

摘要： A lock-up control device for a lock-up torque converter of an automatic transmission is provided which starts measuring an elapsed time when the throttle opening exceeds a first predetermined value due to depression of an accelerator pedal during lock-up clutch slip control. When the throttle opening exceeds a second predetermined value due to sudden depression of the accelerator pedal prior to the elapse of a determination time, a transmission controller terminates the lock-up clutch slip control. After a rapid increase, the slip amount starts decreasing upon termination of the lock-up clutch slip control. Therefore, the temperature of a facing stops rising when the lock-up clutch slip control is terminated, and this improves the durability of the facing. The lock-up clutch slip control is re-started when the throttle opening is reduced to a predetermined value, and this maintains the excellent fuel economy performance.
