Engine torque control device and method, in particular during downshift

摘要

An engine torque control device is configured to provide increase engine output torque during shifting, with excessive engine output torque being prevented while shift shock is reduced. The engine torque control device has an automatic transmission control section (13) that controls an automatic transmission (5) and an engine output torque control section (12) that performs a torque increasing control of an engine output torque to increase the engine output torque during a downshifting so that an actual engine speed will substantially approach a target speed. The allowable time for torque increasing control is set according to the amount of torque increase. If the increase in engine output torque is below a specified value at the point when the allowable time has elapsed, the torque increasing control is continued, but if the torque increase is at or above the specified value when the allowable time has elapsed, the torque increasing control is forcibly halted.
