摘要： A controller is capable of controlling a coupled engine running mode, in which an engine is coupled to wheels and an engine brake is activated by driven rotation of the engine, and a coasting mode, in which an engine brake force is reduced with respect to that in the coupled engine running mode with mode with the engine brake on, and starts the coasting mode on the basis of the steering angle of a steering member. The controller starts the execution of a first coasting mode when the steering angle is equal to or less than a preset upper limit value and starts the execution of a second coasting mode when the steering angle is greater than the upper limit value. In the first coasting mode, the engine rotation is stopped, and in the second coasting mode, the engine remains rotating.

摘要： Suppressing deterioration ofNV performance caused by a change in a transmission input torque after engagement of an engagement device in a vehicle power transmission device including a transmission having a predetermined shift stage formed with engagement of a one-way clutch in addition to engagement of the engagement device.
If a vehicle request torque (e.g., transmission input torque T AT ) is changed after the engagement of a brake B2, a torque capacity of the brake B2 (engagement oil pressure of the brake B2) is temporarily reduced without changing the first speed gear stage. Therefore, the aligning action of the one-way clutch F1 is utilized when the brake B2 is temporarily slipped or released, and the rotating member CA23 fixed at the first speed gear stage is aligned. Therefore, the deterioration of NV performance occurring due to a change in the vehicle request torque after engagement of the brake B2 can be suppressed.

摘要： In a hydraulic control apparatus for a vehicular automatic transmission (10), if it is determined that there is a failure that may cause tie-up in an automatic transmission (10), communication is provided between a first output port (38c) and a first drain port (38a) in a switching valve (36). As a result, a hydraulic frictional engagement device, which should be disengaged when there is a failure, is disengaged. Also, a specific shift speed is achieved by controlling the switching valve (36). Therefore, it is not necessary to select a shift speed that is achieved on the condition that the hydraulic frictional engagement device, which should be disengaged when there is a failure, is engaged. Thus, it is possible to prevent a shift that may impair driveability when there is a failure that may cause tie-up in the automatic transmission (10).

摘要： Vehicular drive system which is small-sized and/or improved in its fuel economy. A power distributing mechanism 16, which is provided with a differential-state switching device in the form of a switching clutch C0 and a switching brake B0, is switchable by the switching device between a differential state (continuously-variable shifting state) in which the mechanism is operable as an electrically controlled continuously variable transmission, and a fixed-speed-ratio shifting state in which the mechanism is operable as a transmission having a fixed speed ratio or ratios. The power distributing mechanism 16 is placed in the fixed-speed-ratio shifting state during a high-speed running of the vehicle or a high-speed operation of engine 8, so that the output of the engine 8 is transmitted to drive wheels 38 primarily through a mechanical power transmitting path, whereby fuel economy of the vehicle is improved owing to reduction of a loss of conversion of a mechanical energy into an electric energy. The mechanism 16 is also placed in the fixed-speed-ratio shifting state during a high-output operation of the engine 8, so that the required electric reaction of first electric motor M1 can be reduced, whereby the required size of the first electric motor M1, and the required size of the drive system 10 including the electric motor M1 can be reduced.

摘要： The invention relates to a method for operating a drive train (1) of a vehicle during trailing throttle operation using an internal combustion engine (2), an electric machine (3) and a transmission device (4). The electric machine (3) is disposed in the power flux between the internal combustion engine (2) and the transmission device (4). A shifting element (8) with continuously variable transmission capability is provided between the electric machine (3) and an output (5). A target output torque to be applied to the output (5) is dependent on a transmission capability of the shifting element (8). The transmission capability of the shifting element (8) is adjusted in a controlled manner as a function of the necessary target output torque such that the shifting element (8) has a transmission capability as is necessary for obtaining the target output torque at the output (5). A rotational speed of the electric machine (3) is adjusted in a controller manner during a shut-off process of the internal combustion engine (2) in order to maintain the shifting element (8) in a slipping operation at least during the shut-off process of the internal combustion engine (2) and guide the rotational speed of the internal combustion engine (2) to zero by means of the electric machine (3).

摘要： An engine (1) and generator/motor (26) are connected to the input shaft of a continuously variable transmission (30), and the output shaft (37) of the continuously variable transmission is connected to drive wheels. A target value of a coasting torque acting on the output shaft during coasting is set according to a vehicle speed. A real coasting torque is estimated from the output torque of the engine and frictional torque of the continuously variable transmission. By making the generator/motor function as a generator or a motor, fluctuation of the engine braking force due to a variation of drive ratio during coasting is suppressed so that the real coasting torque coincides with the target value.
