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.
