Training
Chassis & Control: braking, steering
Braking and steering, from tire forces to control laws, safety concepts and vehicle tests.
- Duration
- 2–3 days
- Format
- On-site · modular · hands-on workshops on real cases
This training connects vehicle dynamics, braking and steering hardware, control functions and their safety requirements, including by-wire architectures. Content is adapted to the participants’ programs, from conventional hydraulic systems to brake-by-wire and steer-by-wire. Workshops use realistic cases such as regenerative blending, ESC intervention analysis or a steering feel assessment.
