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.

Control System for a Vehicle Drivetrain

Номер: US20120302401A1
Автор: John William Edward Fuller
Принадлежит: Torotrak Development Ltd

The invention concerns an arrangement for controlling a vehicle drivetrain having an engine provided with a speed governor and a continuously variable transmission (“CVT”) incorporating a variator which is constructed and arranged to regulate its reaction torque. The control system comprises a control part ( 504 ) movable by the driver to provide a driver input, an open loop subsystem ( 511 ) for operatively coupling the control part to the governor ( 520 ) to control no-load speed of the governor in dependence on the driver input, a closed loop subsystem comprising a comparator ( 502 ) which receives a first control signal deprived from the driver input and corresponding to a target engine speed, and a second control signal corresponding to engine speed, and which adjusts variator reaction torque in dependence upon a comparison of the first and second control signals causing the transmission to load the engine suitably to achieve the target engine speed.

Disclosed is a gear shift indicator which can reduce bothersome feelings of the driver. The EFI-ECU acquires information about the travelling state of a vehicle, and calculates a target gear shift stage for improving fuel consumption. The EFI-ECU acquires information about a current gear shift stage. The EFI-ECU determines that a gear shift request is generated when the current gear shift stage is different from the target gear shift stage. When the EFI-ECU determines that an AI control is under execution and that the target gear shift stage calculated in the Step is a restricted gear shift stage prohibited in the AI control, the EFI-ECU does not present a gear shift indication.

Torque ratio estimating apparatus for continuously variable transmission and lateral pressure control apparatus for continuously variable transmission

Номер: US20120316016A1
Автор: Kyohei Sakagami
Принадлежит: Honda Motor Co Ltd

When estimating a torque ratio (Tr), which is the ratio of an actually transmitted torque relative to the maximum transmittable torque of a continuously variable transmission, based on the transmission characteristics for transmitting a given variable component of an input shaft element to an output shaft element via a frictional element, since the torque ratio (Tr) is estimated from a slip identifier (IDslip), which is an indicator for difference in amplitude of a variable component between the two elements, or a phase lag (Δφ), which is an indicator for difference in phase of the variable component between the two elements, it is possible to estimate the torque ratio (Tr), which is very closely related to the power transmission efficiency of the continuously variable transmission, with good precision, thus improving the power transmission efficiency. Moreover, since the torque ratio (Tr) is estimated from the slip identifier (IDslip) or the phase lag (Δφ), it is possible to minimize the number of sensors necessary for estimation, this reducing the cost.

Assembly with a planetary gear train for a motor vehicle, a motor vehicle and a method for operating a planetary gear train

Номер: US20130029804A1
Автор: Andreas Misala
Принадлежит: Audi AG

In an assembly with a planetary gear train, which includes the elements sun gear, planet carrier with planetary gears and ring gear, two elements, in particular the sun gear and the planet carrier, are coupled with each other via an overrunning clutch. A clutch bridges the overrunning clutch. Bridging is discontinuous and controlled by a control device based on the relative rotation of the two elements to be coupled. For example, one rotation speed sensor can measure the rotation speed of an electric machine, whereas another rotation speed sensor can measure the rotation speed of a crankshaft of an combustion engine. In a motor vehicle, the combustion engine can be coupled with an electric machine, using different gear ratios during startup or boosting and in generator operation. In addition, the electric machine can drive an air-conditioning compressor when the combustion engine is not running.

A maximum gear ratio rate of change corresponding to the non-limited desired gear ratio and an actual gear ratio of the continuously variable transmission is selected from an electronically stored gear ratio rate map. A current desired gear ratio is determined based on a previous desired gear ratio and the maximum gear ratio rate of change. A commanded gear ratio of the continuously variable transmission is changed to the current desired gear ratio using electronic signals.

Engine-overrun-preventing control device for work vehicle

Номер: US20130218428A1
Автор: Hideyuki Hiraiwa, Jun Hashimoto, Shinji Kaneko, Yoshitaka Onodera
Принадлежит: KOMATSU LTD

In an engine-overrun-preventing control device, if an engine speed exceeds a maximum speed, a minimum value of an inching rate is set such that higher the actual engine speed results in a higher minimum value of an inching rate. The hydraulic pump displacement is adjusted to obtain a higher inching rate between the minimum value of the inching rate and an inching rate set based on a brake stroke. If the engine speed exceeds a commanded speed and a pressure time-rate-of-change at the pump intake exceeds a prescribed value, the minimum value of the inching rate is set such that the higher the pressure time-rate-of-change, the higher the minimum value of the inching rate. The pump displacement is adjusted to obtain a higher inching rate between the minimum value of the inching rate set based on the pressure time-rate-of-change and the inching rate set based on the brake stroke.

A storage section stores inching characteristic information. The inching characteristic information defines a relationship between an inching operation quantity and an inching characteristic value. The inching characteristic value is a value dependent on pilot pressure that is reduced through inching control. A computing section references the inching characteristic information to thereby compute, from the inching operation quantity detected by the inching operation quantity detector, a command value to the pilot pressure control valve. In the inching characteristic information, a rate of lowering the inching characteristic value when the inching operation quantity is within a first range is greater than a rate of lowering the inching characteristic value when the inching operation quantity is within a second range greater than the first range.
