Powertrain Functional Safety

Powertrain Functional Safety

5 days
This course is not scheduled.
Who should attend?


    • Engineers, managers and technicians involved in the development of mechatronic systems and powertrains, from design to after-sales who want to incorporate in the design and utilization the principles of functional safety.


  • Advanced
  • This course provides designers of automotive systems with a deeper knowledge on functional safety in order to select the right architecture for the powertrain.
  • For example, functional safety ISO 26262 standard or VDA state of the art safety modify engines or gearbox technologies.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • identify risks in mechatronic systems and in particular powertrain systems (engine and gearbox),
  • understand the risks of the system over its life in all their aspects: hardware, software and interfaces,
  • develop and implement a process of building a safe operating architecture (specification and validation) adapted to the context of the project and the criticality of the identified risks,
  • develop or validate a case study for safety,
  • identify key regulatory requirements and current standards for safety.
