Prius PHEV User Interfaces

From My wiki
Jump to navigation Jump to search

This page addresses user interface and State Of Charge Manipulation management device options for Prius PHEV conversions. Such a device would need to be capable of executing logic similar to this Prius PHEV Pseudo Code. Though an actuall Interface or display may not be required so long as the SOC manipulation is handled properly, such an interface is still desireable because it provides the user with feedback and might also allow for user interaction and configuration. Conversly a management device may not be required to perform SOC Manipulation functions with certain conversion methods though the data they provide about the vehicles opperation may still be valuable.

CAN-View Scanner

The CAN-View is now the first official user interface for 2004 & 2005 Prius PHEV conversions.

My CAN Project

OK, not "My" Can Project, but some very nice software none the less.

CAN232 Wiring
May Required Linux and all that that entails

Utilizing a CAN232 (CAN to RS232 device)
You will need an OBDII to DB9 cable similar to Cable #7, perhaps.
This File:CAN232.pdf may be helpful when trying to communicate.


User:PeterAstrand has created an Open Source Linux based CAN bus data visualizer for the Toyota Prius based on the work of Attila Vass and his My CAN Project.

Simple CANbus scanner

Find attached a few photos of my (Jim Fell) simple CANbus controller for the Prius. It just reads the three messages of relevance from the oem battery pack and can process any control algorithm necessary then send the signals to Rich Rudman's PFC. See FellUK for Jims conversion.
