An object of the present invention is to provide a forward collision avoidance assistance system that attains the reduction of driver's uncomfortable feeling and the improvement in drivability while ensuring the collision avoidance performance during operation for avoiding contact with an object. A collision avoidance calculation unit 3 determines a risk of collision between a host vehicle and an object detected in the host vehicle traveling direction based on information about the host vehicle detected by a host vehicle information detection unit 1 and information about the object detected by an object information detection unit 2, and calculates control information for object avoidance to be output to an actuator 5 based on a result of collision risk judgment. The collision avoidance calculation unit 3 uses a collision-avoidable limit distance Deltaxctl2 determined based on a physical limit that can avoid collision with the object, and a jerk-limited collision avoidable distance Deltaxctl1 determined based on the acceleration and jerk generated on the host vehicle by object avoidance movement, to control the brake force generated on the host vehicle by a brake actuator 5.
