Does cruise save energy at all?

4The first IEEE International Electric Vehicle Conference

Insist a FIXED speed is the problem, too much breaks. Should let nature take its course:

Eco-friendly Cruise Cruise (ECC) does not set the fixed speed, we only set the upper and lower limits:

•let the car slow down by itself, when there is a car in front, •or speed up when the car behind is pushing.

What safe and saving rules to enforce?

9The first IEEE International Electric Vehicle Conference

•The car should not drive in the blind spot of the cruise car; •The car should not drive in position the cruise car falls in its blind spot;

•The car should not drive side by side, it blocks the passing traffic; •The car should maintain the same distance between the front and the back car.

method Pros Cons

Queuing Delay bound No rush hour

Matrix Numerical fitting No Fractal

Deterministic Rush hour analysis No distribution

Dynamic Chaotic analysis No empiric

The first IEEE International Electric Vehicle Conference

Each has its own merits, we use rush hour analysis for this particular study

Allow cruise speed variations between 75km/hr to 115 km/hr

Conclusion and future work

The conceptual networked cruise model and its related design issues are addressed.

Simulations regarding Fractal traffic are touched upon, to promote the green and safe driving concepts.

In the future, the simulations combining both physical layers light design

and road dynamics test will get us much closer to the real world scenarios.
