摘要： A torque detection mechanism can be provided for a power train and its control unit without newly adding a sensor and its signal processing module. As a gear pair for the torque detection mechanism of a phase difference type, existing gears in a transmission are used, or a gear pair for this mechanism are provided adjacent to these existing gears. From phase signals sent from pickups, a phase difference signal is obtained by use of one part of existing devices in the control unit. The torque detection mechanism can be realized with the minimum number of component parts by utilizing the existing members and spaces instead of newly adding a sensor and its module. The invention can be applied to either of FF and FR cars, and has a practical structure in respect of the performance, costs and reliability.

摘要： The present invention relates to a method and an apparatus for controlling a car equipped with an automatic transmission having a lockup clutch. According to the control method of the present invention, when the lockup clutch is in the lockup state, a variation of a generated torque is detected. When the range of the torque variation detected exceeds a predetermined value, an engine torque is reduced by controlling the engine, and the automatic transmission is controlled to compensate for a reduction of the driving torque due to a reduction of the engine torque. Thus, the speed change ratio is changed to the low gear side. The control unit of the present invention includes a unit for controlling an output torque of an engine according to a command value, a unit for changing the transmission ratio of the automatic transmission, a unit for detecting a variation of the engine torque, a unit for deciding a target driving torque, a unit for reducing a torque command value when the range of a detected variation of the torque has exceeded a predetermined value when the lockup clutch was in the lockup state, and a unit for deciding a transmission ratio at which the reduction of the driving torque due to the reduction of the engine torque is compensated for.

摘要： A part of the air flowing through a main passage flows into a by-pass passage. A flow rate detector is provided in the by-pass passage. An outlet of the by-pass passage is opened at the narrowest portion of a venturi structure provided in the main passage. The by-pass passage is in communication with a pressure-accumulating chamber, which is in communication with the main passage at the portion thereof which is on the downstream side of the venturi structure. The pressure of the air flowing backward from the engine is stored in the pressure-accumulating chamber. The pressure in the pressure-accumulating chamber serves as a passage resistance with respect to the flow of the air in the by-pass passage. Accordingly, the flow rate detector permits determining the flow rate of the air, which does not contain a component representative of a backward flow of the air.

摘要： The present invention relates to a method and an apparatus for controlling a car equipped with an automatic transmission having a lockup clutch. According to the control method of the present invention, when the lockup clutch is in the lockup state, a variation of a generated torque is detected. When the range of the torque variation detected exceeds a predetermined value, an engine torque is reduced by controlling the engine, and the automatic transmission is controlled to compensate for a reduction of the driving torque due to a reduction of the engine torque. Thus, the speed change ratio is changed to the low gear side. The control unit of the present invention includes a unit for controlling an output torque of an engine according to a command value, a unit for hanging the transmission ratio of the automatic transmission, a unit for detecting a variation of the engine torque, a unit for deciding a target driving torque, a unit for reducing a torque command value when the range of a detected variation of the torque has exceeded a predetermined value when the lockup clutch was in the lockup state, and a unit for deciding a transmission ratio at which the reduction of the driving torque due to the reduction of the engine torque is compensated for.
摘要翻译：本发明涉及一种用于控制配备有具有锁止离合器的自动变速器的汽车的方法和装置。根据本发明的控制方法，当锁止离合器处于锁止状态时，检测到产生的转矩的变化。当检测到的扭矩变化的范围超过预定值时，通过控制发动机来减小发动机扭矩，并且控制自动变速器以补偿由于发动机转矩的降低引起的驱动转矩的降低。因此，变速比变为低档侧。本发明的控制单元包括：用于根据指令值控制发动机的输出转矩的单元，用于悬挂自动变速器的变速比的单元，用于检测发动机扭矩的变化的单元，用于决定目标驱动转矩的单元，当锁止离合器处于锁止状态时，当检测到的扭矩变化的范围已经超过预定值时，用于减小转矩指令值的单元，以及用于确定传动比的单元，补偿由于发动机转矩的降低引起的驱动转矩的降低。
