摘要： PROBLEM TO BE SOLVED: To provide engine output control capable of high-dimensionally balancing engine output control required to have responsiveness with engine output control required to have steady stability.
SOLUTION: When a gear shift operation is not being executed before t1 or after t2, engine torque limitation by ignition time control is prohibited by setting an engine torque limit value Tetvo by throttle opening control at the sum value of a V belt-protecting engine torque limit value Teb, an oil pump loss torque compensation value Tep and a transmission response controlling inertia torque compensation value Tet (Tet=0 when the gear shift operation is not executed), and by setting an engine torque limit value Teign by ignition time control at the outputtable maximum value Temax. When the gear shift operation is being executed from t1 to t2, Tetvo and Teign are set to Teb+Tep and Teb+Tep+Tet, respectively. The throttle opening TVO and the ignition time are determined to reflect Tetvo and Teign as shown in the figure. Tetvo and Teign coincide with t1 and t2; when the gear shift operation is being executed from t1 to t2, Tet is achieved by highly-responsive ignition time control, and Teb and Tep are achieved by throttle opening control excelling in steady stability.

摘要： PROBLEM TO BE SOLVED: To surely prevent big shock when switching forward mode to reverse one due to an operating error while allowing intentional forwarding/reversing operation. SOLUTION: In a control unit 20, when switching to a reverse mode during forward mode of a vehicle, based on a mode signal from an inhibitor switch 22 and detected vehicle speed from a vehicle speed sensor 21, the detected vehicle speed is compared with a first vehicle speed. At the same time, the time when advancing mode is selected before switching over to the reverse mode is compared with the prescribed judgement time. When the vehicle speed is the first vehicle speed or lower and the time when advancing mode is selected is the prescribed judgement time or less, switching to the reversing mode is executed. Otherwise, switching to the reversing mode is delayed. COPYRIGHT: (C)2004,JPO
