The system problem

Challenge

The electrification team needed to interface with a production loader whose control behaviour was not available as a clean specification. Progress depended on understanding the machine's modules, identifying the relevant sensor and control signals, and reproducing them safely enough to validate the new architecture.

Our responsibility

SSH Tech led the technical investigation and prototype integration: instrumenting the vehicle, observing module behaviour, forming and testing interface hypotheses, and turning the findings into a demonstrable control-system bridge.

How we worked

  • Established a safe instrumentation plan around the machine and its existing control modules.
  • Captured and correlated bus traffic with physical inputs, outputs and operating states.
  • Reproduced target sensor signals in a controlled prototype rather than attempting a full-system replacement at once.
  • Used the prototype to expose integration risks early and give commercial stakeholders a concrete proof point.

Delivery path

Hardest risk first.

Phase 1

Observe the existing machine

Built an evidence base connecting vehicle behaviour to the messages and signals moving through the control system.

  • Vehicle instrumentation and signal capture
  • Module and interface mapping
  • Operating-state correlation

Phase 2

Reproduce the critical interface

Implemented a bounded signal-reproduction layer to test whether the electrification architecture could communicate with the loader.

  • Sensor-signal emulation
  • Control-interface prototyping
  • Bench and machine-side validation

Phase 3

Prove the delivery path

Packaged the technical findings and working prototype into a clear basis for the next stage of engineering.

  • Risk and interface documentation
  • Prototype demonstration
  • Defined next-stage integration scope
