Abstract:
An output torque control system for an internal combustion engine for a vehicle, said engine having an automatic transmission, the system comprising:engine output torque-changing means operable during gear shifting of said automatic transmission, for changing output torque of said engine so as to reduce a shock caused by said gear shifting;vehicle speed change rate-determining means for determining a rate of change in traveling speed of said vehicle;termination timing-determining means for determining timing of termination of said changing of said output torque of said engine by said engine output torque-changing means, based on said rate of change in the traveling speed of said vehicle determined by said vehicle speed change rate-determining means and a response delay of said output torque of said engine to said changing of said output torque of said engine by said engine output torque-changing means; andcontrol-terminating means for terminating said changing of said output torque of said engine by said engine output torque-changing means, at said timing of termination determined by said termination timing-determining means.
