ABSTRACT:
In order to alleviate shocks occurring when an automatic transmission driven by an engine shifts between reduction ratios, the engine is caused to change its output torque by an amount indicated by a target torque variation. The target torque variation is set in response to an estimated engine revolution speed variation before and after the shifting operation.
