Abstract
A control system serves for surely preventing occurrence of a shift shock due to engagement of a one-way clutch with an automatic transmission in non-shift condition, and comprises a disengagement detecter for detecting disengagement of the one-way clutch; a power-on detecter for detecting change in an operation of the engine from driven mode to drive mode; a throttle opening detecter for detecting a throttle opening of the engine; a throttle opening estimater for estimating a second throttle opening when a predetermined time has elapsed from the time at which the operation of the engine is changed from driven mode to drive mode, on the basis of a first throttle opening detected when the operation of the engine is changed from driven mode to drive mode; and a torque down instructer for generating a torque down signal for reducing the output torque of the engine when the estimated second throttle opening is not less than a predetermined reference value.
