摘要:
A method and system to control transmission shifting in a motor vehicle having an automatic transmission is provided, wherein a command for a transmission up-shift is detected, and, inhibited, based upon operator input, engine speed, and vehicle operating conditions. A fuel cutoff event is immediately implemented, along with electrical energy regeneration using vehicle kinetic energy. Operator input includes monitoring accelerator pedal input, and inhibiting the command for the transmission up-shift when a tip-out event occurs. The command for inhibiting the transmission up-shift is discontinued when an accelerator pedal tip-in is detected, or accelerator pedal position is greater than a calibrated value, or when engine output torque exceeds a torque threshold, or when engine speed exceeds a speed threshold.
