ABSTRACT:
A method and apparatus for automatic braking of a vehicle includes a number of elements which operate to control vehicle speed as the vehicle enters upcoming curves. A road shape detection device detects a road shape in a forward direction of a vehicle, and a proper vehicle travelling speed calculating device calculates a proper vehicle travelling speed in the forward direction, based upon the detected road shape. A vehicle speed detecting device detects a speed of the vehicle, and a deceleration setting device sets a vehicle deceleration. A brake control device is connected to the deceleration setting device, the vehicle speed detecting device, and the proper vehicle travelling speed calculating device, for reducing the vehicle speed according to the vehicle deceleration. A road surface friction detecting device detects a value corresponding to a frictional or slippery condition of the road surface. A deceleration correcting device increases the deceleration as the road surface becomes more slippery.
