Genesis G90 smart-seat evaluation — Hyundai Motor Group industry-partner study

Contributed to an industry-partner study with Hyundai Motor Group evaluating a next-generation smart seat for the Genesis G90, using 14 air-cell actuators to auto-balance left/right body pressure and sustain driver comfort during long-duration driving. Owned the experimental workflow end to end, including participant recruitment, real-vehicle testing, multi-channel data logging, statistical analysis, and technical reporting to Hyundai Motor Group. IRB-approved: KMU-202503-HR-461.

Participant anthropometric measurement session

Participant recruitment and anthropometric profiling

Recruited 12 IRB-approved participants (8M/4F, mean age 29.3), each with ≥5,000 km annual mileage or ≥3 years of driving experience. Collected anthropometric data including stature, sitting height, weight, and body-type segmentation to align the cohort with the target user profile for G90 driver-seat comfort evaluation.

Genesis G90 limousine test vehicle

Real-vehicle comfort evaluation on the Genesis G90

Conducted 2-hour controlled test drives in a Genesis G90 over a fixed university-to-expressway round-trip route, administering mid-drive comfort surveys every 30 minutes. Collected 65+ hours of synchronized multi-channel data, including pressure distribution, air-cell activity, seat position, subjective comfort scores, and in-cabin video.

Smart-seat instrumentation and hardware swap

Smart-seat instrumentation and hardware fault resolution

Configured the smart-seat instrumentation rig, including 14-channel ADC-logged pressure-distribution sensors across the back, cushion, and bolster regions, and 14 air-cell actuators supporting the auto-balancing logic. Diagnosed an air-cell exhaust fault that caused repeated last-value entries during deflation events, coordinated seat replacement with Hyundai Motor Group engineers, and revalidated the replacement unit before resuming testing.

In-cabin live sensor monitoring laptop

Live sensor monitoring and data-integrity validation

Monitored every real-vehicle test run in real time, tracking pressure-mat distribution, air-cell intake/exhaust behavior, seat position, and synchronized driver video during on-road driving. Cross-checked vehicle logs against time-stamped data records to identify logging anomalies before downstream statistical analysis.

Competitor luxury sedan benchmarking

Competitor-vehicle seat-comfort benchmarking

Conducted 2-hour benchmark drives with competitor luxury sedans, including Mercedes-Maybach, under the same test protocol used for the Genesis G90. Compared subjective comfort scores against the G90 baseline to inform the next firmware iteration.

Final report presentation at Hyundai Motor Group Namyang R&D Center

Final report and on-site presentation at Hyundai Motor Group Namyang R&D Center

Authored a 150-page completion report and presented findings to Hyundai Motor Group engineers at the Namyang R&D Center. Summarized statistical evidence that the air-cell logic improved long-duration driver comfort and provided firmware recommendations for the next iteration.
