摘要:
A control system for a power transmission system capable of speed change control in conformity of a deceleration demand. The transmission system includes at least two transmission units having different responsiveness to a speed change and capable of setting a speed change ratio individually, and in which a total speed change ratio is determined according to the speed change ratios of the transmission units. The control system includes a speed change control for changing a priority order to carry out a speed change operation of the individual transmission units to achieve a predetermined deceleration in conformity with a content of the deceleration demand, when the predetermined deceleration is demanded.

摘要:
A power transmission unit in which an inspection and tuning of an electric motor can be carried out easily. In the power transmission unit, a rotor of the electric motor is arranged between a first shaft of an input side and a second shaft of an output side, and in which the first shaft, the second shaft, and the rotor are integrally connected at least in a rotational direction. The first shaft is connected with the rotor, and the first shaft is also connected with the second shaft.

A control system capable of ensuring an engine braking force and a drive force even in case a failure occurs in a speed change ratio control or a deceleration control of an automatic transmission. The control system includes: a failure detecting mechanism for detecting a failure to set any of predetermined speed change ratios; and a speed change commanding mechanism for outputting a speed change command to set a speed change ratio larger than the current speed change ratio in accordance with a signal outputted when the failure detecting mechanism detects the failure.
摘要:
A second electric motor is arranged on a first axis on which an output shaft of the engine is arranged, a transmission is arranged on a second axis which is parallel with the first axis, and a clutch is arranged on the first axis to selectively connect and disconnect the second electric motor and the transmission to and from the engine. Power on the first axis is transmitted to an input shaft of the transmission via a power transmitting mechanism.

A hydraulic control apparatus for an automatic transmission includes a forward travel engaging element, a reverse travel engaging element, a first signal electromagnetic valve, a first switching valve, and a second switching valve. The hydraulic control apparatus is structured so as to change the output state of the signal pressure of the first signal electromagnetic valve when changing from the reverse travel shift position and/or shift range to the non-travel shift position and/or shift range and when changing from the forward travel shift position and/or shift range to the non-travel shift position and/or shift range, and to enable quick draining of hydraulic pressure of the hydraulic servo of the reverse travel engaging element and hydraulic pressure of the hydraulic servo of the forward travel engaging element.
