Baolong recently obtained a nomination for the dual-chamber dual-valve air suspension controller from a leading global automaker. This is a key milestone from domestic to overseas markets, marking the company's technical leap in high-end intelligent suspension controllers and also represents that the company’s platform capability meets international automaker’s standards.  

This air suspension controller serves as the “brain” for the dual-chamber dual-valve air suspension solution, handling decision-making. For this project, the actuator is a dual-chamber dual-valve air spring damper, with two separate chambers and two separate valves adjusting air pressure and damping for different road excitation frequencies and intensities. Compared with coil spring electronically controlled dampers or single-chamber single-valve air springs, the dual-chamber dual-valve solution significantly improves damping adjustment precision, wide-frequency adaptability, comfort on complex roads, and handling stability, becoming one of the standard solutions for new-generation high-end vehicles.  

This dual-chamber dual-valve air suspension controller features hardware based on an existing platform extended with dual-chamber dual-valve control channels for development and debugging; and software based on the AUTOSAR architecture with added driver software, reconstructed damping control algorithms, pressure closed-loop control, and fault diagnosis strategies; The structural design achieves a fusion of dual-chamber dual-valve cavity layout and integration solutions, while remaining compatible with existing mounting holes and terminal definitions.

In the future, Baolong will keep expanding the overseas market of intelligent suspension, and is building production facilities in several locations abroad to better supply to global automakers.
