Abstract:
A brake control system for a vehicle comprising:an object sensing device for sensing an object positioned in the direction in which the vehicle is advancing,braking devices for braking the vehicle,a determination means, coupled to said object sensing device for determining the possibility of contact between the vehicle and the object based upon the relative positions of the vehicle and the object based on the output of said object sensing device,an automatic braking means coupled to said determination means for carrying out an automatic braking by operation of said braking devices based on the output of said determination means, andan abnormal road surface condition sensing means coupled to said automatic braking means, for sensing an abnormal road surface condition wherein the coefficients of friction of the road surface are different for right and left wheels of the vehicle, and wherein when said abnormal road surface condition sensing means senses an abnormal road surface condition, said automatic braking means sets a rising gradient of the braking force for the automatic braking, lower than the rising gradient when an abnormal road surface condition is not sensed.
