Saw this term at NVIDIA.

Ah yes, this is what Aryan is explaining to me.

Types of ECUs (main ones):
- Engine Control Module (ECM)
- Anti-lock Braking System (ABS) Control Module
- Electronic Power Assisted Steering (EPAS)
- Transmission Control Module (TCM)
- Traction Control Unit (TCU)
how are all the ECUs connected in a car? is there like a central computer
No, it’s decentralized, connected through a complex network.
Yes, there’s also a ODB port that can be used to read the state of the car (velocity, steering, etc). You can imagine this as a read-only port, you can’t use it to send commands to the car.
