Seat Controller Unit

Overview

Description

As vehicle interiors evolve toward greater comfort, personalization, safety, and wellness, automotive seats are transforming from passive components into intelligent electromechanical systems. Modern seat architectures now integrate multiple motors, sensors, power management, connectivity, and advanced safety features across all vehicle segments. Scalable controller architectures enable a seamless range of capabilities—from basic electric adjustment to premium features such as heating, ventilation, massage, occupancy detection, and personalized memory settings. Designed for flexibility and modularity, these platforms support cost-efficient integration while meeting the increasing demands for performance, user experience, and functional safety.

System Benefits:

  • Scalable seat control architecture supporting vehicle segments ranging from economy to luxury, with modular feature expansion
  • Optimized BOM cost through the reuse of common electronics across multiple seat configurations and vehicle classes
  • Integrated safety and sensing readiness for occupancy detection, seat-belt detection, and related safety functions
  • Flexible power management and I/O expansion using PMICs and GreenPAK™ devices to support growing feature sets
