FSAE DAQ Development
Data acquisition pipeline for Lehigh Racing — resurrected VBox hardware, serial ingest, and test-day logging workflow.
プロジェクトの焦点
車両テストとシミュレーション
Key Features
Legacy box refurbishment
Lap trigger alignment
Population data sanity checks
Scope of work
Stand up a test-day data acquisition path for Lehigh Racing when team hardware was neglected and logging was inconsistent:
- Audit existing DAQ enclosure, power, and GPS antenna routing
- Integrate personal RACELOGIC VBox unit as interim logger
- Define serial ingest and file naming so analysis scripts could run after test days
- Document trigger points (start/finish, sector splits) for driver coaching
- Train drivers on consistent power-up and storage swap checklist
Out of scope: custom PCB design, cloud telemetry, live strategy dashboard.
Timeline
| Phase | Window | Milestone |
|---|---|---|
| Hardware triage | Spring 2018 | Inventory team box vs. personal VBox |
| Bench validation | Spring 2018 | Power, GPS lock, CAN/serial smoke tests |
| Track shakedown | May 2018 | First logged test day with aligned lap triggers |
| Process doc | May 2018 | Pre-session checklist and file handoff to analysis |
Stack & BOM (hardware / software)
| Item | Qty | Role |
|---|---|---|
| RACELOGIC VBox | 1 | Primary logger (interim team unit) |
| GPS antenna + mount | 1 | Lap timing and speed traces |
| 12 V loom + fuse | 1 | Vehicle power integration |
| Laptop + analysis scripts | 1 | Post-session CSV review |
| Team DAQ enclosure (legacy) | 1 | Evaluated for refurbishment — partial reuse |
Deliverables
- Working logger configuration for test days
- Serial comms path validated on bench
- Lap file naming convention for downstream MATLAB/Python tools
- Full team-box PCB rebuild (deferred)
- Automated radio telemetry (out of scope)
Outcomes
- Restored repeatable logging after a season of ad-hoc captures
- Caught GPS mis-mount and trigger offset issues before they polluted tire models
- Accidentally sampled population-scale data once — added checklist item to verify session config
Risks & mitigations
| Risk | Mitigation |
|---|---|
| Storage full mid-session | Swap protocol + pre-session format check |
| Loose antenna | Torque spec on mount + visual pre-grid walk |
| Mixed logger configs | Single canonical settings file per event |
