To provide a control device and a method making drivability and safety compatible by realizing target acceleration/deceleration required by a driver under safe traveling environment and changing target acceleration/deceleration so as to make safe traveling preferential when encountered to dangerous traveling environment.
Driver target deceleration Gt is operated in response to required deceleration inputted from an acceleration/deceleration detection means of a driver and vehicle speed V is inputted from a vehicle speed detection means. Target speed Vt2 is set based on a distance D2 to a front corner of the vehicle, radius R of curvature of the corner, road surface friction coefficient μ and vehicle gravity center position information k20 and setting target deceleration Fd2/W is determined based on the vehicle speed V and the target speed Vt2. When the driver target deceleration Gt is larger than the setting target deceleration Fd2/W, the automobile is controlled so as to become the setting target deceleration Fd2/W.
