摘要： The vehicle control device is designed to control a vehicle equipped with an engine (10), and an automatic transmission (200) comprising a torque converter (202) with a lockup clutch (202f). The vehicle control device comprises a controller (50) configured to perform control of changing an engagement degree of the lockup clutch (202f) and to, when such a condition that the vehicle is traveling and a steering angle-related value as a parameter related to a steering angle of a steering apparatus of the vehicle increases is satisfied, reduce an output toque of the engine (10) to generate a deceleration of the vehicle to thereby execute a torque reduction control for controlling an attitude of the vehicle. The controller (50) is configured to reduce the output toque of the engine (10), in accordance with the engagement degree of the lockup clutch (202f) controlled by a lockup control.
