PURPOSE:To control the speed without giving sensations of fear and danger to a driver by using road information picked up by a visual device to adapt the vehicle speed in curve parts of a road to a human sense. CONSTITUTION:An image sensor 1 like a television camera is used to detect the road condition in the front of a vehicle, and the detection result is sent to a road recognizing part 2. The road recognizing part 2 recognizes the road area in the front of the vehicle based on the inputted road image. A deviation area evaluating part 3 compares the road area recognized by the road recognizing part 2 with a standard road pattern based on it to calculate the deviation area. A speed controller 4 sends a throttle control signal to a throttle valve 6 and sends a brake control signal to a brake damping part 9 provided on a wheel 7 based on the deviation area calculated by the deviation area evaluating part 3, the speed set by a speed setting part 5, and a speed measured signal which is actually measured by a vehicle speed sensor 8 and is fed back to the speed controller 4, thereby controlling the speed without giving sensations of fear and danger to the driver.
