Cooperative Adaptive Cruise Control System Two or more vehicles
to communicate and work together to avoid a collision.
Transmitting information about its speed and acceleration to the car behind it.

3 Main Components
1.1. Radar Based SystemRadar Based System -Report on the width,
distance , and speed of objects ahead .
2.2. Headway Control UnitHeadway Control Unit- Control the Brake, Throttle , Dashboard display.
3.3. Image-ProcessorImage-Processor- Combines the data, feeding it to the headway control unit that controls the car

Basic theory
The Cars communicate with one another by exchanging radio signals.
It will then work out a safe following distance on the basis of their actual performance characteristics.
