Idea: hypermiling cruise control
How about a cruise control designed for hypermiling? Someone could probably modify a cheap after market cruise control to be more fuel efficient. Maybe have it recieving data that the scangauge gets. Then write a small computer program to read the data from the port, and control the throttle. It could use info like rpms, speed, throttle position. And do easy accelerations. It could tweaked to maximize the gas milage, but with the ease of a cruise control. It can maybe even learn. I have a programable thremostat at home that learns the heating characteristics of the room. It learns that if it sends x amount of power for y seconds, the room temperature will by z. That way it can keep the room temp pretty consistent. The cruise control could learn the characteristics of the car.
The electronics is beyond me, but I could probably do the programming stuff. |
I want a pulse and glide cruise control, that would be sweet

I may be a little off on the times as far as cruise control technology, but do any of the advanced cruise controls adjust for distance between cars yet? If so is the distance between cars programmable?

I work with ACC, I do system integration for the module that receives the decel commands from the ACC radar module. There are several manufacturers with these systems, not just Honda. Cadillac, VW, BMW all have an ACC option on most models that is 30 kph and higher with no collision mitigation. Most future car platforms that have ACC (which I can't tell you guys) does actually have collision mitigation. I know how the whole system works to a T.
The cruise control idea is interesting. It is cake if you can control the engine via a CAN message as in most newer cars. You would probably have to find a way to overide the cruise control module in the car and tap into the CAN bus with a new module. The problem will come in when you go to a cable puller type cruise control. That would have to either have a learning algorithm (which them makes the electronics more complicated possibly) or it must be programmed for that car. Each car is going to respond different to the cable pulling. In the end you'd never get your money back for the system in gas savings. |
Hi, I made a Cruise Control (with MPG sensitive logic) and posted all the making process at this thread:
