Outline Introduction and background situation Basic theory of Cooperative Adaptive Cruise Control System Cost Conclusion
Introduction In each year traffic accident 200 people are killed and people injured Cost HKSAR about 30 million dollars
- 95% accident is due by driver error Introduction - What kinds of driver errors ?
Situation Most problem are too close and wrong turn How to solve it ? 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. Radar Based System -Report on the width, distance, and speed of objects ahead. 2. Headway Control Unit - Control the Brake, Throttle, Dashboard display. 3. Image-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.
