Embedded system engineer - SR Suntour GmbH
I worked at SR Suntour as an Embedded System Engineer in the Research & Development team.
Our current project is the development of an Ebike, from its development phase, to its production. This
is extremely challenging,
especially with a small team but it provides so much satisfaction to see the progress and what we are
capable of.
The project requires a lot of knowledges and skills that I am improving each day. I go through many
steps: From the design the circuit and PCB of the controller,
prototypying some parts with a 3D printer, to the coding of the algorithm to control the motor, this
experience is really rich and intense.
Technologies involved:
Brushless motor control
Different communication protocol: CAN, SPI, I2C, BLE, ANT+
EN-15194 E-bike safety standard
Continuous Integration
EMC testing
My contribution:
- Development of a complete software to interface the system (Diagnostic tool): flashing, error detection, automatic testing, etc...
- Continous integration and improvement of the firmware for the controller : sleep mode, CAN bus integration, code optimization, bootloader...
- Re-design of the dongle and other electronic boards for internal uses (data acquisition).
- Support for the asian teams, our different suppliers and the management.
- Follow-up on a project involving a semi-active suspension used for the UCI world cup and the Tokyo Olympics games.
Field application engineer - VIE program - Akka GmbH
After my Diploma of engineering I made a VIE (Volontariat International en Entreprise).
It is a french program that gives the opportunity to young people to work abroad in a french company
group.
During this program I discovered the automotive industry and its plenty of technologies and processes. I
was involved for the commissioning of test bench,
and had the opportunity to travel to the USA to install a test bench to a customer.
I also developped two application: a new Head Up Display interface for a customer for the CES Las Vegas,
and an application for Akka that introduces all the service the company
can provide.
Technologies involved:
Hardware in the loop (HIL) testing
PROVEtech
Automotive communication protocol (CAN, LIN, Flexray)
Qt and C++
Signal filtering
My contribution:
- Management of the construction and continous development of Hardware-In the-Loop (HIL) integration on a test bench
- Commissioning of the new ECUs on test benches
- Requirements analysis and verification of simulation models
- Programming software application: new HUD display design and presentation application using QML
Electrical engineer - Final project internship - Liebherr France SAS
As a last internship during my engineering school, I decided to do my internship at Liebherr, in Colmar
(France). The goal was to build
a test bench for
a new excavator that was released by Liebherr. The project had two topics:
The development of the embedded hardware. This consisted of a bunch of Arduino boards to be connected to
a PC, and making
the electronic interface to the part of the excavator. The role of some Arduinos was to emulate the
signals of the sensors (4-20mA
current loop for
the hydraulic and pressure sensor for instance), simulating the CAN bus communication, etc...
The development of a graphical user interface (GUI) to give the user a friendly interface to monitor and
control the test
bench. This GUi was coded in C++ with the Qt libraries.
Technologies involved:
CAN BUS SAE J1939
Real time operation
Many sensor's technology: Hall, 4-20mA current loop, resistive ...
Qt and C++
Signal filtering
My contribution:
- Designing the electronic architecture of an excavator simulator
- Programming AVR microcontroller (Arduino)
- Simulating sensors with 4-20mA current loop, resistors...
- Developing the software written in C++ with QT library
