Seat control application solution based on Jihai G32A1445 realizes multiple functions

According to the International Energy Agency (IEA), the total number of electric vehicles in the world will expand to 350 million in 2030. With the rapid development of the automobile industry, electric seats have become a standard feature of automobiles and an important direction for automobile companies to upgrade their products. The comfort and safety of electric seats directly affect the overall experience of drivers and passengers. Stimulated by the further upgrading of consumer demand, the market value and intelligent functions of electric seats will continue to increase.

In order to help customers quickly complete project design and maximize the application requirements of seat controllers , Jihai launched a seat controller application solution based on the G32A1445 automotive general-purpose MCU . Its hardware control circuit has a compact structure and a high degree of integration. It also has excellent performance in cost control and anti-interference .

G32A1445 Seat Controller Application Solution

The G32A1445 seat controller application solution uses its intelligent algorithm and high-efficiency performance to achieve integrated control of position adjustment, angle adjustment, memory, massage, ventilation, heating and other functions. At the same time, through the self-learning function in the control system , it automatically measures the limit position of the seat in the car, effectively preventing the motor from being damaged due to long-term stalling.

The solution is mainly composed of sensors, motors , communication circuits, power supplies, etc. The main control uses the Jihai G32A1445 automotive general-purpose MCU, which uses the built-in EEPROM of the chip to store seat memory data and provide a one-key recovery seat adjustment function; G32A1445 receives sensor data, accurately controls the motor, drives the ventilation fan, lumbar pillow, headrest and backrest, etc. to optimize seat comfort, and realizes the switch heating function to further enhance the driving experience. At the same time, the solution supports real-time monitoring of the power supply function, calibrates the motor rotation torque through algorithms, realizes overcurrent protection , prevents abnormal stalling, etc., to ensure the stability and reliability of the entire system.
