Abstract: When a transmission selector lever is operated from P or N range to D range, an input clutch to be engaged at the fifth gear position is temporally engaged to reduce shift shock when the engaging element for the first gear position is engaged. An oil pressure command value for actuating the input clutch is increased with a constant inclination from a start point oil pressure value, and the start point oil pressure value is lowered when the engine speed is low or when an oil temperature is high. Even if a timing of completion of filling of working fluid to the input clutch is fluctuated, the difference between the actual oil pressure and the oil pressure command value is suppressed to a small level and the occurrence of shock due to surge at the time of the filling completion is prevented.

Abstract: A focus condition sensing device comprises a first imaging device unit and a second imaging device unit, which are mounted in parallel on a single IC chip board. Integrating operation start signals are set to “H” (High), so that an integrating (accumulating) operation is started in each of the imaging device units. Chip enabling signals are changed between “H” and “L”, and thus, it is determined whether the integrating operation has been completed in the first or second imaging device. When one of outputs of the first and second imaging devices exceeds an AGC level, it is deemed that the integrating operation of the corresponding imaging device is completed, and thus, electric charges are output from the imaging device.

Abstract: An initial command oil pressure of a lock-up control of coasting lock-up region is set by using a lock-up learning correction amount calculated by a learning control in a lockup control of the other of the plurality of lock-up regions such as slip lock-up region and complete lock-up region when one of the lock-up control of these other lock-up regions is performed before the lock-up control of the coasting lock-up region. Thus, a lock-up learning correction amount can be commonly used among three kinds of lock-up regions, and a lock-up as set is early realized in each lock-up region.

Abstract: A standby phase target time is determined with reference to a table according to a read engine load and vehicle speed. A standby phase real time is then measured, and a learning correction value is calculated and stored. In a next shifting operation, a value that is found by adding the learning correction value to a hydraulic pressure command value in the previous shifting operation is used as a new hydraulic pressure command value. This learning correction is performed in small regions where the vehicle speed increases with the throttle opening being substantially constant. This accurately compensates a change in characteristics of a hydraulic system without being affected by a rapid change in torque or the like.

Abstract: A pressure regulating valve regulates an original pressure outputted from a manual valve by means of a control pressure generated by a solenoid in a D range and supplies the regulated original pressure to an engaging element. An electronic control unit filters a current signal supplied to the solenoid to generate the control pressure by using a strong filter when a N range is switched to a D range during stoppage of a vehicle so that the control pressure has a gentle rise characteristic, switches the filtering process to a filtering process using a weak filter to rapidly move the pressure regulating valve in a working pressure discharge direction when the N range is switched to the D range during running of the vehicle and returns the filtering process to the filtering process using a strong filter after a predetermined time period. Thereby, occurrence of shock is suppressed when the D range is again selected after the N range is selected during running in the D range.

Abstract: A lockup control system for a torque converter of a vehicle equipped with an air conditioner. The lockup control system maintains a coasting slip restricted state of the torque converter even during coasting of the vehicle with an accelerator pedal released, for restricting slip rotation between input and output elements of the torque converter. The coasting slip restricted state is achieved by a coasting lockup capacity that is lower than a lockup capacity of the torque converter in a driving condition of the vehicle with the accelerator pedal depressed. According to the invention, the coasting lockup capacity is controlled according to an operation load of the air conditioner and increased as the operation load of the air conditioner increases.

The shift control system includes timer means for counting an elapsed time after a shift operation has been started. The elapsed time is compared with a predetermined first re-shift permission time in the case of automatic shift operation and with a predetermined second re-shift permission time in the case of manual shift operation. The first re-shift permission time and the second re-shift permission time are different from each other to optimize the shift control both in the automatic shift mode and in the manual shift mode.

Abstract: In an automatic transmission performing change-over of a first engaging element and a second engaging element between two gear positions, for example between the fourth gear and the fifth gear, an oil pressure command value A to one of these two engaging elements is retained as a current value “a” and an oil pressure command value B to the other of these two engaging elements is retained as a current value “b” and at the same time the calculation of a calculation value of a downshift form the fifth gear is started when a target gear position changes to the fourth gear or lower during upshift between the two gear positions. When downshift calculation values Ad, Bd reach the retained values “a”, “b”, the oil pressure command values A, B are switched to the downshift calculation values.
