Seat heating, ventilation and massage are popular automotive comfort features powered by the seat control module. This core ECU is developed and validated per QC/T 950, ISO 17987 and ISO 11898‑1 automotive standards.
Acting as the system brain, the integrated module communicates with vehicle controllers over LIN or CAN bus. It uses PWM for zoned heating with NTC sensors and over‑temperature protection. It adjusts fan speed to eliminate heat and moisture for ventilation, and drives massage motors or air pumps with stall detection against overload damage.
Built‑in fault self‑diagnosis reduces or cuts power and reports errors for short‑circuit, open‑circuit or current anomalies. It withstands rigorous EMC, vibration, temperature and dust‑water tests for tough on‑vehicle environments.
Superior to distributed controllers, this design simplifies wiring, reduces parts and eases assembly. For new‑energy vehicles, it optimises power consumption, balancing premium seating comfort and energy efficiency.
