Mission: Development of an Analysis Tool to operate on measurements coming from hydraulic test benches of an ESP (brake systems) where all sensors are integrated into it.
Problematic:
This tool has the aim to find out the correlation between several signals (acceleration signals, pressure signals, etc.). Indeed, there are some disturbances on those signals because most of the sensors are integrated into the master circuit (no bus system), and these correlations will help the application software team to find out some filters to delete these disturbances.
This project is divided into two parts:
* The first one consists of computing the data sets in order to extract the interesting information (FFT, peak hold spectrum, statistics, etc.)
The goal is to compute the analysis automatically on plenty of input files (more than 10000) and to store the results into a database.
* The post processing part is the exploitation part : the final user can also sort the analysis and begin the exploitation of the measures (aggregation of data results sets, sort by certain characteristics, ...)
Activities:
* Analysis of the requirements (i.e. which analysis should be done) ;
* Draft of the architecture ;
* Framework and test definitions (demo Matlab) ;
* Integrations tests definitions ;
* Documentation
BOSCH gain: Today, the analyses are done automatically, and the exploitation of the results is easier and faster due to the use of the database.
Environment:
* Language: Matlab, Java
* Development: Matlab, Eclipse ;
* Configuration and version: Subversion (Tortoise) ;
* Database: MySQL.

Mission: Software Development of the bus system of an ESP (Electronic Stability Program) for the BMW series 5
Goals:
* Network Development: FLEXRAY for an ESP
* Implementation of the frames of a FLEXRAY bus
Activities:
* Analysis of the customer requirements ;
* Software implementation, by processing on several architectural layers: from the interface with the applicative software down to the design of the bus (timeout, checksum and alive counter), through the signal conversion layer for the conversion of the physical values coming from the sensors.
* Creation of test scripts to validate each frame with an integrated simulation environment (to see as a black box): we simulate the environment of the bus by simulating the frames.
* Automation of the unit tests by deploying a continuous integration tool within the team: we do some regression tests in order to check that all the signals are well implemented before each delivery.
* Integration tests to verify some functionalities on test benches (HIL from DSpace) in order to test the implementation as in a real way with emulators. These tests are processed just before the tests on the target car.
The frames are used to communicate between the sensors and the master circuit. Each customer chooses his sensors, in order to adapt the values coming from these sensors to the applicative software, which is the component which realizes the functions of the ESP.
BOSCH gain: The signals can be validated using an automatic test, before each release. Therefore, the CMMI policy has been applied.
Environment:
* Language: embedded C ;
* Development: Microsoft Visual, Eclipse, CUBAS Tool ;
* Configuration and version: TCM (IBM), Subversion ;
* Request Management: Rational Clearquest (IBM), Bugzilla, JIRA. ;
* Requirements: DOORS (IBM). ;
