    摘要： A control system for an internal combustion engine for a vehicle has an automatic transmission. The control system is operable during gear shifting of the automatic transmission, for changing output torque of the engine to reduce a shock generated during the gear shifting. During gear shifting in which a change gear ratio of the automatic transmission is to be increased, upon stepping-on of the accelerator pedal of the vehicle, the output torque of the engine is increased by a first predetermined amount based on an operating condition of the vehicle when an increase occurs in the rotational speed of the engine due to the gear shifting. After the output torque of the engine is increased by the first predetermined amount, the output torque of the engine is decreased by a second predetermined amount based on the operating condition of the vehicle. After the output torque of the engine is decreased by the second predetermined amount, the output torque of the engine is progressively recovered to a value assumed upon completion of the gear shifting.

    摘要： A shift control apparatus for an automatic transmission having an automatic shift mode and a manual shift mode. The shift control apparatus includes a shift characteristic changing unit for changing the first shift characteristic to a second shift characteristic such that a region for outputting an upshift signal is displaced toward higher vehicle speeds after performing a downshift by the manual operation, a delaying unit for delaying the output of the upshift signal by a predetermined time period according to the vehicle running condition when the vehicle running condition becomes a condition where the upshift signal is to be output according to the second shift characteristic, and an upshift allowing unit for once allowing the output of the upshift signal when the above condition continues after the elapse of the predetermined time period determined by the delaying unit.

    摘要： A control system (a control valve CV and an electronic control unit ECU) for an automatic transmission TM performs an automatic control to select and establish a speed ratio from a plurality of speed ratios in response to the condition of a vehicle which is set in a drive range. This control system creates a neutral condition if the vehicle is stationary with the brake of the vehicle being actuated and the accelerator for the engine being turned off while the transmission is set in a drive range. The control system is also equipped with an engine output control device 50 that adjusts the engine output which is input into the transmission when the transmission in the drive range leaves the neutral condition and starts to establish any of the speed ratios in the drive range.

    摘要： A drive control device is provided for a vehicle which has an automatic transmission and which is capable of setting a throttle opening independently of an accelerator opening. Herein, the drive control device detects a shift range and an engine speed, based on which prescribed controls are made with regard to a throttle and a clutch. That is, if the engine speed is higher than a predetermined engine speed value when the shift range is changed over from a non-running range (e.g., N range) to a running range (e.g., D range), the drive control device controls the throttle opening substantially in a fully closed state while controlling clutch oil pressure of a start-mode-engaged gear to be set at a predetermined oil pressure value which is greater than zero and at which the clutch does not have a torque transmission capacity. In addition, in a predetermined time after the engine speed becomes lower than the predetermined engine speed value, the drive control device maintains the throttle opening in the fully closed state while gradually increasing the clutch oil pressure of the start-mode-engaged gear so as to control the clutch to start an engagement operation. Thus, it is possible to ease an engagement shock of the clutch which occurs when the driver changes gears from the N range to the D range while depressing the accelerator pedal.
