Process & QA

A Proven Path to Reliable OEM Mobile Control Systems

Building robust mobile control systems for specialty vehicles is complex—hydraulics, CAN bus controls, J1939 controls, sensors, HMIs, and production realities all have to work as one. Our Process & QA framework de‑risks integrations, creates clean documentation, and validates performance in harsh field conditions. The result is rugged control systems your operators trust and your production team can scale.

Our Process

A quality‑driven engineering process from requirements through commissioning—so your vehicles launch on time, run safely, and stay easy to service.

1) Discovery & Requirements Capture

We align early with engineering, production, and service teams to define:

  • Functional requirements, safety interlocks, modes, and operating states
  • I/O map, network nodes, J1939/SPN/FMI needs, and diagnostics expectations
  • Hydraulic functions (flows/pressures), sensors, and mechanical interfaces
  • Compliance and customer requirements; high‑risk areas and constraints

 

Deliverables: Requirements brief, preliminary I/O map, risk register.

2) System Architecture & Design

We translate requirements into a coherent machine architecture:

  • Network topology, address plan, termination, bandwidth and loading
  • J1939 message set/DBC, gateway strategy (chassis CAN ↔ body CAN)
  • Hydraulic schematics, valve/manifold selection, sensor specification
  • Safety concept and state‑machine design; fault handling and limp/home modes

 

Deliverables: Architecture pack, network drawings, preliminary schematics.

3) Detailed Engineering & Documentation
  • ECU software design, control loops (PWM/current), and tuning plan
  • Harness drawings/cut lists, panel/enclosure layouts, labeling conventions
  • HMI screen maps, service menus, iconography and language strategy

 

Deliverables: Rev‑controlled schematics, harness sets, software design docs, HMI UI kit.

4) Prototyping & Bench Validation
  • Hardware‑in‑the‑Loop (HIL) and bench tests for I/O, messaging, and timing
  • Simulated sensor/actuator loads; boundary and fault injection testing
  • Acceptance criteria and test reports tied to requirements

 

Deliverables: Bench validation report, updated risk mitigations.

5) Machine Integration & Field Trials
  • First‑article build support, sensor calibration, valve tuning, and HMI refinement
  • DV/PV field testing under real duty cycles; data logging and issue tracking

 

Deliverables: Field trial plan & reports, change log, operator feedback summary.

6) Quality Assurance & Verification
  • Structured test plans with traceability to requirements/FMEAs
  • Environmental and durability checks appropriate to the application (vibration, temperature, ingress, electrical)
  • CAN diagnostics validation (DM1/DM2, SPN/FMI mapping, events and counters)

 

Deliverables: QA verification pack, non‑conformance records, corrective actions.

7) Production Readiness
  • End‑of‑Line (EOL) test procedures and fixtures; production checklists
  • Work instructions, torque specs, harness routing, and receiving/inspection guides
  • Kit/BOM finalization with alternates and service spares

 

Deliverables: Production release set, EOL procedures, training plan.

8) Commissioning, Training & Handover
  • Onsite startup support for pilot and first‑run units
  • Operator/service training, quick‑start guides, and troubleshooting flows
  • Signed acceptance with punch‑list closure

 

Deliverables: Commissioning report, training materials, approved revisions.

9) Lifecycle Support & Change Control
  • Revision control for software, HMI, schematics, and documentation
  • Field updates/bootloader strategy; sustaining engineering and obsolescence management
  • Warranty support collaboration and continuous improvements across model years

 

Deliverables: Change‑control log, release notes, service bulletins.

Our QA Principles

Traceability

Every requirement maps to tests and documentation.

Serviceability

Diagnostics and HMI integration designed for rapid field troubleshooting.

Repeatability

Production‑friendly harnessing, labeling, and EOL tests reduce variation.

Safety & Uptime

Interlocks and fail‑safes prioritized to protect operators and equipment.
