摘要： A dual clutch automatic transmission includes a one-way clutch provided in a driving force transmission path that establishes a certain gear ratio in a first set of gear ratios. A driving transmission direction of the one-way clutch is set such that a rotation inputted from a wheel side to an output member in a predetermined rotational direction is transmitted to the input shaft. The predetermined rotational direction corresponds to a backward movement of a vehicle. On condition that the traveling state of the vehicle reaches a predetermined deceleration state, switching control of setting the gears for the first set to a neutral position can be executed.

摘要： The system comprises an oil pump driven in conjunction with an output shaft of a transmission, a first oil path for supplying oil discharged from the oil pump to a lubrication system of the transmission, a second oil path arranged in parallel with the first oil path to guide the oil from the oil pump to a heat exchanger, and a valve inserted on an upstream side of the heat exchanger in the second oil path. The valve opens at a first set pressure to conduct the oil from the oil pump to the second oil path. The oil is supplied to the first oil path in a low vehicle speed area below the first set pressure, so that oil supply necessary for the lubrication system can be ensured. The oil is supplied to the second oil path in a high vehicle speed area over the first set pressure.

摘要： A cooling device for cooling lubrication oil which circulates in a vehicle transmission is provided with a first oil circulating circuit through which a clutch oil for lubricating a first and second clutch of the transmission circulates, a second oil circulating circuit through which a gear oil circulates to lubricate mechanisms other than the first and the second clutches, and a cooling water circulating circuit through which a cooling water circulates to cool an engine and a motor. Also provided is a first heat exchanger exchanging heat between the first lubrication oil and the second lubrication oil, and a second heat exchanger exchanging heat between the first lubrication oil and the cooling water.

摘要： A system and method of compensating for torque converter slip in a motor vehicle include measuring rotational speeds of an engine crankshaft and mainshaft, as well as measuring operating temperatures of a fluid associated with the motor vehicle. Engine output torque is adjusted as required by controlling some combination of ignition timing, intake air flow, fuel injection, and accessory load. A system and method for deactivating a torque compensation system retrieves a number of times the torque compensation system has been activated over a set period. If the number exceeds a predetermined number of activations, the torque compensation system is deactivated.

摘要： Since an oil level of oil in a first space housing a transmission mechanism is lower than an oil level of the oil in a second space housing a differential gear, not only is it possible to lubricate a drive pinion and a ring gear housed in the second space with a sufficient amount of oil while cutting the total amount of oil compared with a case in which the oil levels of the first space and the second space are both high, but it is also possible to reduce the resistance of oil to stirring in the second space by discharging excess oil building up in the second space to the first space via a second oil passage formed along an axial center of a pinion shaft, and to prevent the oil level of the first space from decreasing excessively, thus avoiding aeration of an oil pump.
