ABSTRACT:
The invention prevents a clutch from being damaged and ensures a driver of a feeling of responsiveness even if an accelerator pedal is depressed when an automatic transmission is shifted from a drive range to a non-drive range. If neutral has been selected and if an accelerator has been operated, an ECT_ECU performs normal throttle control until lapse of a first period of time following operation of the accelerator exceeds a second threshold. Within a second period of time following the first period of time, the ECT_ECU executes a program including the regulation of throttle opening at less than the amount corresponding to degree of accelerator depression in normal control, until lapse of a predetermined time subsequent to detection of the shift.
