Method for operating a vehicle drive train

Номер: US20120022752A1
Автор: Christian Popp, Jörg ARNOLD, Klaus Steinhauser, Valentine Herbeth
Принадлежит: ZF FRIEDRICHSHAFEN AG

A method of operating a vehicle drive-train with an engine and a transmission during a gearshift in which an interlocking shift element is disengaged and a frictional shift element is engaged. Upon a shift command, the shifting time and a transmission input speed are monitored. If the input speed deviates from a synchronous speed equivalent to the gear ratio being disengaged, recognizing disengagement of the interlocking shifting element. If an engaged operating condition of the interlocking shifting element to be disengaged is detected, after the lapse of a time interval beginning with the shift command, a current drive torque of the drive machine is brought by motor actuation to a level that corresponds to a difference between the current transmission input torque and a torque that can be transmitted by the frictional shifting element to be engaged, operating with slip, plus a torque offset value.

Method for operating a transmission device with a plurality of friction-locking and positive-locking shifting elements

Номер: US20120029778A1
Автор: Georg Mihatsch, Jörg ARNOLD, Valentine Herbeth
Принадлежит: ZF FRIEDRICHSHAFEN AG

A method of operating a transmission device comprising friction-locking and form-locking shift elements for obtaining different gear ratios. A shift request for engaging a shift element undergoes a time delay dependent upon an operating state prior to a time of engagement of the shift element. A rotational speed differential between halves of the shift element lies within a rotational speed differential window required for the engagement procedure is assigned to the time of engagement. A gradient of the transmission input speed is ascertained at the time of the shift request, and the actual gradient is subsequently monitored and compared with the gradient that existed at the time of the shift request. If an absolute deviation greater than a threshold value is ascertained, the time delay is changed or an actuation of another shift element to be disengaged is varied such that the deviation is reduced below the threshold value.

Electro-mechanical drive with extended constant power speed range

Номер: US20120081059A1
Автор: Bernard Edwin Romig
Принадлежит: Deere and Co

Embodiments of the invention comprise a multi-input range box driven by multiple electric drives. Range shifting involves momentarily increasing the current through all but a given motor, to a level that will carry the entire load, comprising specified constant power. Simultaneously, torque of the given motor is reduced to zero. The given motor is then disconnected from supplying power, is synchronized to the input speed of the new speed range, and is then engaged for the new range. The above sequence is then repeated for each remaining motors, in turn. The motor current is re-equalized for all of the motors, after all the motors have been connected to provide power at the new range. Thus, there is no interruption in power flow during a range shift, and the motors are always used to deliver power, rather than to serve as a brake.

A method of executing an electric-only (EV) mode transition in a vehicle includes determining vehicle operating values using a control system, processing the values to identify the transition, and executing the transition to or from the first or second EV mode. The transition is executed by selectively engaging and disengaging the input brake to zero, and by using the first and/or second traction motor to synchronize slip across the input brake. When the transition is from the first to the second EV mode or vice versa, the control system may use multiple speed and torque control phases to enter multiple intermediate modes, e.g., a pair of engine-on electrically-variable transmission modes and a fixed gear mode. A vehicle includes an engine, an input brake, first and second traction motors, and a transmission driven via the motors in a first and second EV mode. The vehicle includes the control system noted above.

Автор: Benjamin Kaehler, Christopher A. Tuckfield, Klaus Kersting, Markus Brouwer
Принадлежит: CHRYSLER GROUP LLC

A hybrid powertrain for a vehicle having a disconnect clutch located between an internal combustion engine, or other power source, and a hybrid transmission. When deactivated, the disconnect clutch decouples the engine from the hybrid transmission, which enables the hybrid transmission input shaft to rotate independently of the internal combustion engine. This enables enhanced electric drive performance for the hybrid transmission. The disconnect clutch provides for internal combustion engine starting, including internal combustion starting at high vehicle speeds.

A drive train for an automatic transmission for an electromechanical hybrid vehicle is disclosed. The drive train is designed as a whole consisting of only 29 major parts and units, capable of generating 6 forward shifts and 1 reverse shift. A motor is wholly arranged on an input shaft such that the rotation speeds of the motor and the input shaft are synchronous. The motor has the functions of an electric generator and can drive a vehicle to run by a reactive force generated by the magnetic field of the electric generator such that the vehicle generates power during running and therefore avoids consuming the power of the engine due to the load of the electric generator, and thus, the aim of power conservation is achieved. In the hybrid drive mode, the vehicle does not need a clutch and a brake to shift the gear at the moment of startup and during running and therefore realizes stepless transmission and can transmit a large torque.

A method of operating a transmission of a vehicle drive-train when a gearshift from a current gear toward a target gear has been requested. The transmission having frictional shifting elements and at least one interlocking shifting element. If an actuating electrical current, equivalent to a closed operating condition of the frictional shifting element to be engaged, and an actuating electrical current, equivalent to an open operating condition of the interlocking shifting element to be disengaged, are determined while, at the same time, a closed operating condition of the interlocking shifting element to be disengaged is detected by a sensor, a fault is recognized. If the fault is recognized during a predefined test period, one or more selected shifting elements are disengaged and a force flow in the transmission is interrupted. Alternatively, by disengaging the frictional shifting element to be engaged, the current gear is engaged in the transmission.
