DOWN-SHIFT CONTROL SYSTEM BASED ON DRIVER'S INTENTION FOR ACCELERATION |
摘要 |
A down-shift control system is provided, by which if sufficient torque canno t beobtained for an acceleration request or intention at a shift position, a down-shift operation is suitably performed so as to realize a reliable driving capabili ty and no shift-busy phenomenon occurs. The system comprises a section (1) for calcula ting target driving force of a vehicle according to a degree of opening of an accelerato r pedal and a speed of the vehicle; a section (2) for detecting the present shift position of the vehicle; a section (3) for calculating target engine torque based on the target drivi ng force and the present shift position; a section for comparing the target engine torque with a set value determined according to torque characteristics of the engine; a sectio n for performing an accumulating operation relating to the degree of opening if it is judged that the target engine torque equals or exceeds the set value; and a section foroutputting a down-shift command if the accumulated v alue exceeds a threshold relating to the degree of opening. |
