SHIFT CONTROLLER FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To prevent malfunction such as a racing anomaly during a power-on downshift of clutch-to-clutch shifting. SOLUTION: Since feedback control is carried out on a duty ratio DSL1 of a linear solenoid SL1 controlling a release side oil pressure PB1 of a brake B1 during the 4 to 3 power-on downshift and an ante-feedback correction value FB* at a start of the feedback control is changed when the racing anomaly or a tie-up anomaly occurs, the oil pressure PB1 is suitably controlled irrespective of a response delay of the feedback control and the downshift can be quickly carried out while preventing the racing anomaly and the tie-up anomaly. When a turbine rotating speed NT rises and it reaches a neighborhood of a synchronous rotating speed NTDWN after shifting, phase lag control is carried out (TRQ1), and when the racing anomaly occurs, the phase lag control is immediately carried out (TRQ2) to reduce an output of an engine.
