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 speed change controlling apparatus and method for a non-stage change-gear system of the V-belt type or CVT are disclosed, wherein control is performed based particularly on the torque of a non-stage change-gear to meet with a high degree of accuracy requirements in which importance is attached to the fuel cost of a vehicle or the power performance and the time for development of a speed change schedule is avoided. A torque of a change-gear is estimated and speed change control is performed based on a targeted drive shaft torque so that the necessity for a speed change schedule map is eliminated and accurate speed change control based on the torque is performed. Consequently, an object speed change characteristic can be produced readily with a high degree of accuracy. Because matching need not be performed for each vehicle, the development man-hours can be reduced remarkably.

摘要： An automatic transmission, wherein an electric motor is between a couple of clutch shafts of twin-clutch type automatic transmission. The torque and speed of the electric motor establishes a smooth and efficient gear shifting control, and enables a creep control, idling stop starting control, R-to-D, and D-to-R selecting control. As the friction control of the clutch is not performed, smooth gear shift work can be realized. The same control scheme allows creep control, idling stop starting control, R-to-D, and D-to-R selecting control to be enabled, which leads to such an effect that the life is extended without the clutch being worn away.

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： 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.
