221 CONTROL SYSTEM FOR AN AUTOMATIC GEARBOX OF A MOTOR VEHICLE PCT/EP2000/010458 2000-10-24 WO02036384A1 2002-05-10
The invention relates to a control system for an automatic gearbox of a motor vehicle in the event of reduced engine torque. The automatic gearbox is driven by an internal combustion engine which can be influenced by an accelerator pedal, and a signal (HDK) which is proportional to a pedal position is transmitted to an electronic gearbox control system (EGS) in which gear shifting programmes (SKL, SKL red) having gear shifting parameters are stored. The reduced engine torque is taken into account in the selection of the gear shifting programme in such a way that, in a quasi-stationary state and during at least approximately complete load operation, an engine torque reduction factor (k MOM red) is determined, constituting an influencing variable for the selection of the gear shifting programme (SKL, SKL red). The invention also relates to an electronic gearbox control system (EGS) for carrying out the control process.

224 CONTROL APPARATUS US15926091 2018-03-20 US20180283542A1 2018-10-04 Yutaka Ishikawa; Yuya Tachibanada
A control apparatus of an automatic transmission connected to an internal combustion engine of a vehicle includes a determination unit configured to determine an operation state of a hydraulic oil temperature sensor based on comparison between a threshold and a difference between a hydraulic oil temperature of the automatic transmission and a cooling water temperature of the internal combustion engine. When the operation state of the hydraulic oil temperature sensor is determined as normal by the comparison with the threshold, the determination unit further determines the operation state of the hydraulic oil temperature sensor based on an operation state of an oil pressure sensor determined using the hydraulic oil temperature, an oil pressure of hydraulic oil, and a rotation speed.

226 SMART TRANSMISSION SHIFT DELAY METHOD AND SYSTEM FOR CLIMATE CONTROL FOR A VEHICLE US15192504 2016-06-24 US20160305542A1 2016-10-20 Manfred Koberstein; Tina M. Maurer; Stephen R. Dennon; Ranganathan Madhavan; Jim C. Rollinson
A method and system for the cancellation of transmission shift delay as a function of an optimum target temperature is disclosed. Once the pre-selected optimum target is achieved the shift delay is cancelled and the transmission is upshifted. Thus the disclosed inventive concept is based the cancellation of the shift delay on achieving climate control air conditioning comfort targets. Such comfort targets could include one or more of the measured HVAC evaporator temperature, the HVAC discharge temperature, or the in-vehicle cabin temperatures. When a temperature sensor measuring the selected temperature reaches the pre-selected target temperature the shift delay may be cancelled and the transmission may be upshifted, thus maximizing passenger comfort while minimizing fuel consumption. Having the shift delay based upon the achievement of specific measurable comfort targets in the form of target temperatures rather than a set time period allows optimization between cabin comfort and fuel efficiency.
227 Drive force distribution device and method for distributing drive force US11496515 2006-08-01 US07553257B2 2009-06-30 Ryouhei Shigeta; Tomoaki Kato; Akihiro Ohno; Tsuyoshi Murakami; Tadashi Yoshioka; Shunzo Tanaka
An ECU estimates the temperatures of the heat generating portions provided in a drive force transmission system, or a transaxle, a rear differential, and a torque coupling, in correspondence with not only the rotational speed (the differential rotational speed) of each heat generating portion and the torque transmission rate of the torque coupling but also the outside temperature detected by an outside temperature sensor. If the estimated temperature of any of the heat generating portions exceeds a respective predetermined temperature, the ECU controls operation of the torque coupling to suppress overheating of the heat generating portion. That is, the temperature of each heat generating portion is accurately detected through a simplified structure and overheating of the heat generating portion is effectively suppressed.

The method further includes maintaining a substantially zero net torque from the transmission during the heating of the oil by the first and second clutch assemblies.
229 Control apparatus for vehicle and hybrid vehicle US11408023 2006-04-21 US07438664B2 2008-10-21 Kenichi Saito
In a hybrid vehicle incorporating an internal combustion engine having an in-cylinder injector and a motor, when the temperature of the in-cylinder injector rises, if a current engine operation point is inside a prescribed intermediate load range (deposit risk range) where the temperature of the in-cylinder injector tends to rise, an engine load is increased or reduced while an engine speed is maintained, to thereby change the engine operation point to an engine operation point inside a low load range or to an engine point inside a high load range. A reduction or an increase in the engine output associated with the change of the engine operation point is compensated for by increasing or reducing the output of the motor. Thus, deposit accumulation in the in-cylinder injector is avoided.

A clutch controlling device switches the degree of engagement of a clutch according to at least one of the running state of a vehicle, the running state of an engine, or the manipulation state of a gearbox. A detecting device detects the temperature of an emission control catalyst.

Accordingly, the temperature of the catalyst is increased.

238 Method and arrangement for actuating an automatic transmission US299446 1994-09-01 US5501644A 1996-03-26 Hong Zhang
The invention is directed to an arrangement for actuating an automatic transmission of a motor vehicle which is equipped with a drive unit wherein fuel is consumed. The transmission ratios are then so adjusted that the drive unit is driven in its operating range wherein consumption is optimal. The adjustment of the transmission ratio takes place in dependence upon at least a first signal (nab) representing the transmission output rpm and/or the engine rpm and/or the transmission input rpm. Furthermore, the adjustment of the transmission ratio is dependent upon a second signal (moab) which represents a desired value for the torque outputted by the transmission. The adjustment of the transmission ratio then takes place with the aid of a comparison of the first signal and/or the second signal to at least one threshold value (moabstst). According to the invention, the one threshold value is at least dependent upon parameters which influence the maximum torque to be outputted by the drive unit to the transmission.
