Abstract
An ECU executes a program including the steps of: setting a first throttle opening degree (S), setting a low gear torque LTE based on an engine torque map for low gear having the first throttle opening degree and an engine speed (rpm) as parameters (S), setting a high gear torque HTE based on an engine torque map for high gear having the first throttle opening degree and the engine speed as parameters (S), setting a target engine torque TTE by combining the low gear torque LTE and the high gear torque HTE by using a correction ratio KGR determined by a gear step (S), and controlling the engine to produce a required torque set by using the target engine torque TTE (S). In this way a torque can be obtained in accordance with the engine speed.
