    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 method of controlling a multi-step transmission which is connected, via a friction clutch or by a torque converter, to a engine, and, via an axle, to wheels such that when the vehicle is stationary, the engine is running and the drivetrain is disengaged, rolling of the vehicle is prevented or restricted by a shift of the multi-step transmission. The method to prevent rolling includes the step that when the multi-step transmission is in neutral, a safety function is activated, in which actuation of a shift operation element, the accelerator and brake pedals and the current rolling speed are detected by sensors and, if the driving operation elements have not been actuated, then if a predefined rolling speed limit is exceeded, the friction clutch is disengaged if necessary, a starting gear is engaged and the friction clutch is engaged.

    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: A method for operating a torque-transmitting system, which is coupled on the input side to an output shaft of a drive assembly and on the output side to an input shaft of a transmission. A torque flux from the drive assembly to the transmission passes via the torque-transmitting system. The torque-transmitting system includes a hydrodynamic torque converter via which a hydraulic path of the torque flux passes, a converter lockup clutch which is arranged functionally in parallel with the torque converter and via which a mechanical path of the torque flux passes, and a control unit which controls distribution of the torque flux between the hydraulic and mechanical paths in such a way that a predetermined overall torque profile is established at the input shaft of the transmission.
