| Motion and Actuation |
| |
The propulsion and actuation of the systems on board the vehicle are performed through electric motors. Electric traction, power steering, manual transmission, for example, are motor-control applications where STMicroelectronics is able to propose complete solutions based on its product portfolio, power electronics systems know-how and regional application lab's experience. |
