As the global electric vehicle market is projected to reach 350 million units by 2030, according to the International Energy Agency (IEA), the automotive industry is undergoing rapid transformation. Electric seats, now a standard feature, play a crucial role in enhancing both comfort and safety in vehicles. With increasing consumer demand for improved driving experiences, the market value and advanced functionalities of electric seats are expected to rise significantly.

To support efficient project design and maximize the utility of seat controllers, Geehy introduces its seat controller solution, powered by the automotive-grade G32A1445 MCUs. This solution combines compact hardware control circuits with exceptional performance in cost efficiency and interference resistance.

G32A1445 Seat Controller Solution

This solution incorporates intelligent algorithms and high-efficiency systems to manage seat functions, including position and angle adjustment, memory settings, massage, ventilation, and heating. It features a self-learning capability that automatically measures the seat’s movement limits, preventing motor damage due to prolonged stalling.

The solution is composed of sensors, motors, communication circuits, and power supply units. At its core, the G32A1445 MCU stores seat memory data in its built-in EEPROM, enabling one-touch seat adjustment recovery. It processes sensor data to precisely control motors that drive ventilation fans, lumbar support, headrests, and backrests, optimizing seat comfort and activating heating functions. Additionally, real-time power monitoring, motor torque calibration, overcurrent protection, and stall prevention ensure system stability and reliability.
