Human/Prius Centipede

the thing is... the size "1500ah" I don't think you realize the size of that battery will be!

I have two 12v 85ah batteries and each is connected to a 2000w inverter. This is all you need... plus, between all the addon electronics, servers, and other networking equipment I have... I highly doubt you'd pull more power from the batteries/inverter as I do and my next upgrade is to lithium 12v batteries made by using my PIP HV battery cells.

The go pedal is entirely by-wire.

The brake system, though, is not.

 

How do you go about getting legitimate registration and insurance for this?

 

Can I get 3 Prius'? 3,3,3,3,3! Can I get 3?
How about 4? Can I get 4??? 4,4,4,4,4???
5! Can I get 5 Prius' in a row?
Come on now, don't wimp out with just 2!!! Let's get 6!!!

Those who believe this about themselves are usually misinformed....

and yet you can't figure out why one car would not act exactly like another if they both had a single identical signal?

 

Wouldn't it be simpler to just learn how the car works, and then know what you were doing?

There is an electric motor at each throttle. And a spring. The motor can open it. The spring can close it. The signals going to the motor are pulse-width modulated: the wider the pulses, the more the motor will push against the spring.

How does a system like that achieve a target throttle position? By also having a sensor that reports the throttle position. That goes back to the computer that makes the pulses, so the computer can see how it is doing, and adjust the pulses to get the position where it wants, even though the motors are never quite the same and the springs are never quite the same and the flowing air also pushes on the throttle.

What would you propose to be doing through your series of tubes? Duplicate the pulse train being sent to one throttle motor that's under feedback control based on what its position is, and just send the same pulses to a different motor in a different car with a different spring and with no feedback of where its position is, and hope for the best? It's like thinking you can dribble two basketballs by doing identical things with both arms, while only able to see and feel one of them.

Or how about this: since each car already has its own motor and its own spring and its own feedback circuit and its own computer that gets the feedback and knows how to control its motor, why not use your series of tubes to tell those computers how much go you want, and let them do the job they already know how to do?

But would you be sending how much go you want just to the engine control computer in each car? In a Prius, take a step back. Each car also has another computer, called the power management control ECU, that not only knows the car has an engine, it also knows the car has a battery. And when you tell that computer how much go you want, it knows how much go it can get from the battery, and how much go it can get from the engine, and it coordinates the two, and decides how much go to ask the engine computer for, and then the engine computer does the job it already knows how to do with the throttle. And if the two cars haven't got batteries in identical condition at identical state of charge, the computer in each car will know how to do the coordination right for that car, even when that might mean asking for a different amount of go from the engine control computer.

So, how do you go about telling the power management control ECU how much go you want? Well, it turns out there's a pedal for that, wired right to it, with six wires.

Why not just use that to tell the cars how much go you want, and let the computers that are already there do the jobs they already know how to do?

 

An actuator on the brake pedal could be needed because the brake system isn't strictly by wire.

The go pedal is purely an electrical input, six wires to the power management control ECU. Just bringing the same six wires to the other car's power management control ECU might be worth a try.

 

how are you all missing what can be done through CANBUS? well, all but the whole steering wheel linking, once my brain started to think through that, I threw in the towel, have my own projects to think through and that one is just.. nah..

TBH... I bet you post this to the DIYEV or Electric Car Forums, they can tell ya if it's possible or not. Most of those folks are not from the US and from what I've seen and learned a wealth of knowledge from, there isn't a screen name on this forum that can tell you what you need to know! They already hacked into the Gen 3 and Gen 2 Inverter and CVT...heh, powering the Prius guts from a workbench using a homemade HV battery type of folks.
