摘要： A starting clutch control device for an automatic transmission has a starting clutch controller. The starting control device controls a transmission torque capacity of a starting clutch interposed in a transmission path in which rotation of the power source is transmitted to wheels while shifting is underway by the automatic transmission. The starting clutch controller controls the transmission torque capacity of the starting clutch such that a rotation trajectory of the power source develops as desired in a low rotation speed range in which the transmission torque capacity control of the starting clutch is necessary. The starting clutch controller causes the transmission torque capacity of the starting clutch to change, when a shift of the automatic transmission occurs during the transmission torque capacity control by the starting clutch controller, in a direction in which the change in the rotation trajectory will occur corresponding to the shift.

摘要： A control apparatus includes a select lever, an inhibitor switch, a manual valve, a first SOL, a second SOL, and a controller. The controller controls the first SOL and the second SOL such that a hydraulic pressure is supplied to a first friction element and a second friction element when the inhibitor switch detects a D range. The controller determines that an operation position is at an intermediate position when operations of the first friction element and the second friction element are not detected. The controller determines that the first SOL has a failure when the operation of the first friction element is not detected.

摘要： A vehicle transmission apparatus having a starting engagement friction element, which has friction plates and a hydraulic servo including a piston that is moved according to a supplied oil pressure to press the friction plates, which is controlled to be engaged when a vehicle is started by using at least a driving force of the internal combustion engine, and which transfers creep torque. A control device capable of receiving an accelerator operation amount signal and capable of outputting a command value that controls the oil pressure. The control device executes temporary increase control of temporarily increasing the command value, when the accelerator operation amount signal is turned on from a state where the accelerator operation amount signal is off and the command value is output so that the starting engagement friction element transfers the creep torque.

摘要： After engagement of a clutch is suppressed from being started and a rotational speed of an input shaft of an automatic transmission is suppressed from being increased due to an increase in rotation resistance of the input shaft of the automatic transmission, which occurs by half-engagement of a clutch, the clutch is disengaged, and the clutch is completely engaged. In this way, the clutch is completely engaged after the rotational speed of the input shaft is suppressed from being increased. Thus, a heat generation amount of the clutch can be reduced, and furthermore, durability of the clutch can be improved by a reduction in the heat generation amount.

摘要： A transmission control device includes even-numbered and odd-numbered transmission gears selected via a shift mechanism and causes the torque capacities of two clutches to be transitioned to a certain proportion until the clutch rotation speed difference of a low-speed gear-side clutch reaches 0 or approximately 0, sets the torque capacity of the clutch on the low-speed gear side to be the total torque capacity of both clutches, and sets the torque capacity of the clutch on the high-speed gear side to 0. The heat load on the clutch at the time when the vehicle starts to move is reduced and the durability thereof is improved, and the clutch can be made smaller and lighter.

摘要： At an actual engine rotary speed corresponding to a partially engaged state of a starting clutch, a target gear ratio control of a continuously variable transmission is performed by determining a target gear ratio from a target engine rotary speed. At an actual engine rotary speed corresponding to an engaged state of the starting clutch, the gear ratio is controlled in a manner such that the actual engine rotary speed converges with a target engine rotary speed. Accordingly, when it is intended to start the vehicle with a comparatively large throttle opening, it is possible, at the partially engaged condition, to obviate a rise in the actual engine rotary speed with the gear ratio position sticking to a desired position, so that a predetermined driving force is attained when the starting clutch is engaged.

摘要： A method for determining a startup gear in a motor vehicle for starting from standstill while maintaining a load limit of the clutch in a the drive train which comprises a drive engine built as an internal combustion engine, a friction clutch, and an automatic stepped transmission. To avoid overloading the clutch, the method determines a load-independent startup gear with which startup would occur under the present starting conditions without considering the current load state of the clutch and without complying with a load limit of the clutch. A load-specific startup gear is determined as the highest startup gear, with which during a startup under the present starting conditions, a predefined load limit of the clutch would be maintained with consideration given to the present load state of the clutch. The startup gear is the lowest of the load-independent startup gear and the at least one load-specific startup gear.
