Practical, vendor-neutral guides for OEM engineering and sourcing teams working on commercial-vehicle electronics — written the way we’d talk a specification through with a buyer: what changes the part number, and what a supplier needs to quote against.
The architecture-level guide for each product family — the full stack before the individual buyer decisions.
Fuse, relay and junction boxes, commercial vs passenger PDB, and the key sourcing parameters that define a power-distribution box.
Read guideHow the BCM, VCU, gateway and power-management modules divide the work, and how CAN-FD, J1939, LIN and UDS bind them together.
Read guideThe input layer — CAN switch panels, mechanical switches, TPMS and rain-light sensors that feed the BCM and VCU.
Read guideInstrument clusters, CAN displays, CMS electronic mirrors and head-up displays — the cab HMI architecture and how to spec it.
Read guideFocused buyer guides for the decision in front of you, grouped under the product family they belong to.
How to choose a fuse box for a commercial vehicle — blade vs bolt-down, circuit count, ratings and the spec a supplier can build to.
Read guideWhat each one does and which belongs in your power-distribution architecture — the decision upstream of a BCM specification.
Read guideWhen sealing matters, how IP67 is achieved in a PDB, and how to specify a chassis-mount box for wet and exposed locations.
Read guidePower distribution for construction machinery — vibration, dust, temperature and connector choices for off-road duty cycles.
Read guideWhat a heavy-truck body control module controls, how it sits on the CAN / J1939 bus, and how to write a BCM specification.
Read guideWhat a VCU decides on an electric or hybrid truck, how it differs from the BCM and PMU, and how to write a VCU specification.
