Virtual test drive of autonomous vehicle
To launch itsfirst level-4 autonomous vehicle, aFrench car manufacturerhas to ensure its safety and robustness with regard to everyday traffic situations. ALTEN is assisting our customer invirtual based safety testingfor无人驾驶车辆.
To reduce the costs and duration of the tests,ALTEN’s engineers retrieve the data recorded by cars during conventional driving and use it for an ultra-realistic virtual simulation, which means that the vehicles can be tested risk-free on more complex manoeuvres.
ALTEN’s engineers are working, in particular, on:
- Data fusion: the data recorded by the vehicle is processed and filtered in the aim of collecting important information (vehicle response, speed, braking, etc.).
- Environment and vehicle simulation: once the environment and the vehicle have been modelled virtually, the vehicle is randomly subjected to real driving disturbances.
- Correction of discrepancies: lastly, testing under physical conditions helps to identify and correct any handling discrepancies between the virtual and real environment.
ALTEN’s ability to form amultidisciplinary team(data scientists, vehicle dynamics engineers, robotics engineers, simulation modelling engineers) quickly was vital to the success of this project.
