Forward Collision Warning provides the driver an alert if he or she is getting too close to the vehicle in front of them. These are alter only systems, with no active intervention. The main benefit of the alert is to help the driver maintain a safe following distance and help him or her manually avoid a potential collision situation.
Crash Imminent Braking (CIB), Autonomous or Automatic Emergency Braking (AEB) are synonyms basically meaning that when the system determines a collision is imminent, they typically alert the driver and apply braking to attempt to help the driver avoid the collision or help lessen the severity of a collision that may occur. The main benefit is the automatic application of the brakes, which can do more than a warning system, in that the system will alert and then intervene.
Dynamic Brake Support systems typically help the driver apply additional braking power to mitigate a collision. If the system determines the driver is not applying enough braking to mitigate a crash, it will automatically add additional braking to help. The benefit is it can help the driver have enough braking power, as long as the driver has started to apply the brakes.
