SA-003: Sensor cluster
Responsibility
Summary of all input signals required by the EPB: wheel-speed sensors (4x), inclinometer (1x), EPB switch, brake-pedal status, gear position, door open, seatbelt — the last four via CAN.
Interfaces
| Sensor | Type | Source |
|---|---|---|
| Wheel speed x4 | Hall pulses | direct |
| Inclinometer | SPI 1 kHz | direct |
| EPB switch | GPIO | direct |
| Brake pedal | CAN 0x100 | from BCM |
| Gear | CAN 0x110 | from TCU |
| Door / belt | CAN 0x120 | from BCM |
Non-functional properties
- Wheel-speed accuracy: +/- 0.1 km/h above 1 km/h
- Inclinometer accuracy: +/- 0.5°
- Inclinometer sampling rate: 100 Hz
