Stay Green

Hybrid Assistant shows real-time brakes usage:
Green - Regenerative braking
Red - Friction pad braking

Try to stay green!

Back in Black

New version has been published for testers.

Experimenting with a black theme: now coolant temperature has a color code: we've just finished S1, we're at 43 and green to go.

Visual Language

Hybrid Assistant has been designed to avoid information overflow to the driver.
We try to avoid pages of numbers, using other visual cues to convey information.
For example, for the SOC level, colors are used to show the trend: green if charging, red if discharging.
Color saturation is proportional to the battery current value.
This way, the driver can have a quick summary of the status with just a glimpse

Sneak peek

Here is a pre-release of Hybrid Assistant, running on a RAV4 with an home-made tablet stand

First Report

Here is the first report produced live on the car.
Some values are clearly off, but it's a valid proof of concept of whole project.

First steps

We have our first running code.
Xavier has finished the first working version of OBD reading code, while I worked on the State system, based on my previous work on Torque Log Analyzer.

Work in progress...

Currently working hard to bring you the next generation car app.
