摘要： At a torque converter characteristic assuming unit, during non gear shift, gear ratio and an input shaft torque are assumed and also during gear shift, accessory torque is assumed. So as to correct the accessory torque a deviation between pump torque and engine torque is learned and this value is given to the accessory torque, thereby the input shaft torque can be executed and assumed. A drive shaft torque is obtained from a drive shaft torque calculating unit, a control period of the drive shaft torque is determined, a reference drive shaft torque is determined during torque control period from a reference drive shaft torque setting unit. A deviation between the reference drive shaft torque and the drive shaft torque is obtained from a torque deviation executing unit. An engine controlling unit varies the engine torque by controlling an ignition period so as to decrease substantially zero the deviation.

摘要： The invention relates to a control unit for a gear type transmission, a gear type transmission and a vehicle, wherein when torque transmission through the transmitting torque variable mechanism 203, 204 (e.g., an assist clutch) is changed to torque transmission through a meshing gearing 19, 20, 21 after the gearshift, a controlled variable per unit time when the transmitting torque variable mechanism 203, 204 is released is determined or varied according to the vehicle operating condition after a gearshift has been completed. A degraded gearshift feel as a result of axle vibration at the end of the gearshift can thereby be suppressed.

摘要： A transmission control system for a vehicle having an engine with an output shaft, a torque converter, a stepped automatic transmission mechanism, and a clutch for engaging and releasing a plurality of gear shafts and input/output shafts with each other so as to change a shift change ratio by operation of the clutch. The control system produces a shift signal output indicating a shift change ratio of the stepped automatic transmission mechanism, detects an input torque of the stepped automatic transmission, recognizes an actual mechanical shift start timing of the stepped automatic transmission mechanism and changes engaging pressure on the clutch in accordance with a manipulation variable. An input torque-manipulation variable relationship between the input torque and the manipulation variable for every shift change ratio indicated by every shift signal and every mode of shift change ratios is stored. A manipulation variable calculation is performed when the shift signal and the shift signal output changes and the actual mechanical shift start timing is recognized.

摘要： The deterioration of comfortableness is prevented by suppressing the shifting of a timing for releasing a claw clutch (16, 19) due to a change in the characteristic of a friction clutch (25) or the like at the time of torque transmission switching from the claw clutch (16, 19) to the friction clutch (25) during speed changing. A start timing for releasing the claw clutch (16, 19) is learned by learning control means (32) including learning determination means (322) provided to determine a state of the released claw clutch, and learning operation means (321) provided to learn a releasing start. Even when a characteristic change occurs because of a change with time, such as the response delay of an assist clutch (25) or the like, each optimal releasing control timing is learned by the claw clutch learning control means (32).

摘要： The present invention provides an engine power train control method and control apparatus for a vehicle having an engine and an automatic transmission capable of quickly changing an air-fuel ratio to meet the requirements of the exhaust gas without producing shocks and without reducing an engine torque. The invention has following components.
An air-fuel ratio command value is varied stepwise for transition between an air-fuel ratio for lean-burn operation and a stoichiometric air-fuel ratio and, at the same time, an air amount fed to the engine is varied stepwise. In a fixed period following the completion of the stepwise variation of air-fuel ratio command value, a basic fuel amount fed to the engine is varied stepwise from a value determined according to the air amount and an engine speed to a value determined according to a position of an accelerator pedal of the vehicle and the engine speed.
The invention provides that shocks do not occur and the operability is improved, because the engine torque remains substantially constant through the air-fuel ratio transition.摘要翻译： 本发明提供一种用于车辆的发动机动力传动系控制方法和控制装置，其具有发动机和能够快速改变空燃比以满足废气要求而不产生冲击并且不降低发动机扭矩的自动变速器。 本发明具有以下组件。 空燃比指令值为了在稀燃燃烧运转的空燃比和理论空燃比之间的转变而逐步变化，同时，供给发动机的空气量变化 逐步进行。 在空燃比指令值的逐步变化完成之后的固定时间内，供给到发动机的基本燃料量从根据空气量和发动机转速确定的值逐步变化为根据 车辆的加速器踏板的位置和发动机转速。 本发明提供不会发生冲击并提高可操作性，因为发动机扭矩通过空燃比转变保持基本恒定。
