Connected everything (Scooter)

As you probably know, I have been working on a demo around the concept of the Connected Car.
Therefore, I'm interested in everything around this concept.

Yamaha, teaming with Vodafone Automotive is going to sell connected scooter.

Oracle Intelligent Chatbot MOOC

In the (not so much) spare time, I decided to attend to the Oracle Chatbot MOOC.

It has been not so difficult, since I had already an high-level understanding of what is a Chatbot and how our Chatbot (part of Oracle Mobile Enteprise Cloud) is made and working.

But anyway, as always, a MooC takes time, requires coding.

It was useful, tough and in some moments fun.

Have a look at the series of well-crafted video on Youtube, created by my collegues, on the features
of our Mobile Cloud Platform and Intelligent Chatbot.

Here it is.

FUEL_RATE not supported

One of the main features for this project was to be able to calculate the fuel consumption for each trip.
At the beginning I thought it was easy. Every car shows on the display the fuel consumption rate and, probably, it is reliable.
But, it turned out that, at least for now on my Car (a BMW X1) FUEL_RATE and FUEL_LEVEL are not provided (supported) from the OBDII interface.
Even if, if you look at the documentation on Wikipedia, there are the code for reading these parameters.
At the end, I have been able to estimate the gasoline usage starting from the Air Flow Rate (MAF). I'll try to dig a little deeper on the subject.

(My) Connected Car Project: some more data from OBD2

It is not easy, if you don't work every day with cars, to understand what is the meaning of all the data coming from OBD2.

One of the functionalities I wanted to add is to be able to calculate the gasoline consumption for each trip.

Until now, I have not found a measurement coming from OBD2 directly connected to this consumption.
What I have found, and I'm able to read, is MAF, that is the quantity of air consumed, per second.
The gasoline is proportional and therefore MAF is an indirect measure of gasoline consumed.

I have also added to my prototype several other data.

This is the JSON message at this point:

(My) Connected Car: another snapshot of the UI

And this is a first snapshot

The Connected Car Project has a Cloud Backend.
Data coming from the gateway on the car are sent, as MQTT messages, to the IoT backend.
Behind the Message Broker there is a set of MicroServices enabling: data storage, filtering, transformation, visualization and analysis of data.

Data are visualized as a Real Time Dashboard and car's position is shown on a Map.

This is a first snaphot. Not bad.

Documentation, the Open Source Way

I have decided to write and publish online the documentation not only using the Wiki contained in the GitHub project, but also using GitBook, where I'll be developing a more consistent version of the docs.
