OUTPUT SHAFT TORQUE CONTROL DEVICE FOR AUTOMATIC TRANSMISSION

摘要

PURPOSE:To improve converging performance of feedback control for bringing transmission output shaft torque close to target torque at gear change. CONSTITUTION:When an elapsed time T from when start of transmission operation (inertia phase) is detected is less than a predetermined time t1, feedback control for an ignition timing is prohibited (S5 to S6) so as to prevent generation of undershoot accompanying delayed control. And during when the predetermined time t1 has elapsed to reach a target transmission time t2, feedback control for the ignition timing is executed to bring transmission output shaft torque close to target torque.
