When mitigating collisions between a host vehicle and a forward vehicle, the forward vehicle is monitored and real-time data regarding distance and relative acceleration between the host and forward vehicles is used to continuously calculate a collision probability. The collision probability is used to calculate a deceleration request value sufficient to slow or stop the host vehicle within the following distance to the forward vehicle. The deceleration request value is transmitted to an antilock braking system (ABS) controller that caches the most-recently received value for execution upon receipt of an execution command. When the collision probability exceeds a first threshold, the ABS is instructed to arm the braking system. Upon detection of a brake pedal engagement, the ABS executes the brake request with the currently-cached value.
