The problem :

You may not realise it, but electronic communications systems have become a part of our everyday life. This is true in most means of transport and more particularly in our cars.
Today, a range-topping vehicle is fitted with up to 50 ECUs that communicate permanently to improve our safety, our comfort and our fuel consumption.
The systems used to test these ECUs have had to adapt to new rates of production in the factories, quicker changes of model on the production lines and, above all, stringent quality demands (traceability, recurrence, capitalisation, etc.) In 2005, Renault wanted to invest in a hardware and software environment capable of testing and validating its vehicles' on-board electronic systems.

Clemessy took up this challenge :

Renault wanted to move fast and asked us for a first system in just 6 months. Driven and motivated by the challenge, we set up a 15-strong team of engineers specialised in industrial computing, measurement and on-board systems. A partnership with National Instruments, one of the leading players in the measurement and data acquisition sector, got the project off to a good start and produced the right solution: TestInView.

TestInView :

TestInview (TIV) is designed to generate and acquire simple or complex electric signals and to import mathematical models (Matlab/Simulink) that simulate the behaviour of an item of equipment that is absent from its future working environment.
The system's functionality can be used to describe the test sequences, to execute them to within the nearest millisecond and to automatically assess the expected results.
TestInView has already been adopted by the biggest names in the automotive and aerospace industries. It allows the users to focus on their core business, by facilitating and accelerating the simulation, testing and validation of on-board electric systems (controllers and networks), while capitalising on the experience acquired.
This fully modular system integrates functionality specific to each customer, who has an exclusive authorization key for the function in question.
Based on a National Instruments hardware architecture, TIV remains open to other important players on the market (DSPACE, etc.).

Our paths of Research and Development :

  • Integrate other means of communication.
  • Integrate more models. Our goal is to offer manufacturers the possibility of conducting their tests very early in the process, as soon as the new functions and their interactions with existing elements are defined.
  • We are currently working on the feasibility of an interface with AMESIM tools.
  • To develop co-simulation, or the ability to synchronise test sequences on existing and disparate hardware and software assemblies.
