摘要： A target deceleration for running on a curved road ahead of a vehicle is obtained, based on a driver's intention which is input or estimated, and a driver's driving skill level which is input or estimated; and deceleration control is performed so that deceleration applied to the vehicle becomes equal to the target deceleration. In a case where the driver's intention is to cause the vehicle to respond to driving operation relatively quickly, the target deceleration may be set to a relatively small value; and in a case where the driving skill level is relatively high, the target deceleration is set to a relatively small value. Further, the target deceleration is decided based on a state of a road where the vehicle runs.

摘要： It is an object of the invention to provide a shift control apparatus which does not cause a vehicle driver to feel uncomfortable when shift control means resumes normal shift control using a predetermined shift pattern. Where return-to-normal determining means 105 determines that a condition or conditions under which the shift control means 102 resumes shift control using a MEDIUM MODE shift pattern is/are satisfied, return-to-normal permitting means 116 permits the shift control means 102 to resume the shift control using the MEDIUM MODE shift pattern when an output control member release determining means 108 determines that an accelerator pedal 58 has been released. In this arrangement, the driver does not feel uncomfortable even if the transmission is shifted up immediately after the shift control means 102 resumes the shift control using the MEDIUM MODE shift pattern.

摘要： In an automatic transmission, torque shocks are effectively reduced in specific downshifting conditions where relatively strong engine braking occurs as a result of downshifting. When a downshift command to the automatic transmission is detected when an accelerator pedal is not depressed, a valve opening command is issued to a throttle valve so that engine output will have increased by the time the downshifting action of the automatic transmission actually begins, ignition timing is delayed so that an increase in engine output resulting from the opening of the throttle valve by a throttle valve control means is offset for a period starting at the time the engine output actually increases as a result of the opening of the throttle valve by the throttle valve control means and ending at the time the downshifting action of the automatic transmission actually beings, and the ignition timing delaying is cancelled upon initiation of the downshifting action of the automatic transmission.

摘要： A lockup clutch of an automatic transmission is controlled so that no shock is produced while the vehicle is running within a predetermined gear stage. The automatic transmission includes a fluid coupling; a lockup clutch provided in the fluid coupling; a shift selector for selecting a range; a vehicle speed sensor for detecting vehicle speed, and a throttle opening sensor for detecting throttle opening. A control unit determines a gear stage in accordance with the selected range, the vehicle speed and the throttle opening, decides a shift, produces a shifting output signal, decides ON or OFF for the lockup clutch in accordance with the selected range, the vehicle speed and the throttle opening, and produces a lockup ON/OFF output signal. An oil pressure circuit actuates solenoid valves in response to the shifting output signal and the lockup ON/OFF output signal of the control unit. The solenoid valves, in turn, control engagement and release of frictional engagement elements to achieve the decided gear stage and control engagement and release of the lockup clutch. The control unit includes, stored in memory, a lockup diagram set with an ON/OFF hysteresis area; a comparator for deciding whether or not the vehicle speed and the throttle opening, at the time of a shifting output signal is produced, are within the ON/OFF hysteresis area of the lockup diagram; and a lockup output signal generator for turning the lockup output ON if the vehicle speed and the throttle opening are within the ON/OFF hysteresis area when the shifting output signal is produced.
