Mini mainboard as a vcu
Posted: Tue Dec 07, 2021 8:46 am
Good morning, I have a plan to do the following and I just thought I would sense check it here first (I’m learning all the way with this so expect to make mistakes!)
I have a classic mini in which I’m mounting a outlander rear motor. I intend to use the outlander inverter, charger and dcdc with a bmw hybrid battery.
To control the Mitsubishi stuff I have purchased one of Arber’s (on here) can shields and arduino due - this will control these devices over canbus.
I intend to use simpbms to look after the batteries.
My plan was to use Johu’s mini Main board as a sort of vcu and to tie everything together - this may be a bad idea but as said previously it’s all learning!
I’m thinking of using the mini main board to receive signals from the forward reverse neutral switch, the ignition and start switch, the charging lead, the brake and throttle pedals and the regen control.
The mini main board can then send can signals to the Arduino over canbus to control the mitsubishi stuff
The mini main board can control the contactors (via a relay board)
Have I completely lost the plot with this or does it seem like a workable strategy?
I’ve started out by connecting the esp8266 to the mini main board successfully and the next stage for me was to attach my Prius accelerator pedal - I’ve given the pedal 5v and gnd and attached the wiper output to the mini main board but when I look at the gauges through the wifi interface the throttle just seems stuck at 8?
Any guidance anyone can provide would be massively appreciated!
(Apologies for the long rambling post!)
