Tire pressure data into a vehicle CAN bus (J1939)
Most TPMS integration projects fail at the interface, not the sensor. Here is how tire data actually reaches a vehicle controller, what to ask a supplier for, and where deployments usually break.
Technische Notizen aus unserer Entwicklungsarbeit: wie Reifendaten in ein Steuergerät gelangen, was im Feld ausfällt und wie wir die Hardware für eine bestimmte Maschine auswählen.

On a 160-wheel beam carrier one receiver cannot hear every sensor. Repeater placement is a geometry problem, and getting it wrong shows up as intermittent data months later.
