Latest Patents
One of his latest innovations is the electronic controlled fluid suspension system. This system features a longitudinal acceleration sensor, acceleration difference calculation means, and vehicle attitude control means, along with other fluid flow control components known in conventional suspension systems. The vehicle attitude is controlled in response to the difference between maximum and minimum acceleration detected within a predetermined time interval. This innovative approach allows for effective vehicle attitude control without overreacting to momentary changes in acceleration. Additionally, after the vehicle attitude control is executed, a return control is performed to restore the original attitude, followed by a vehicle attitude correction control based on the difference in actual front and rear heights compared to their original heights.
Another notable patent is the air pressure circuit, which consists of a compressor cylinder divided into two chambers by a slidable piston. This circuit includes a suction port and an exhaust port, each equipped with a valve. The system inhales air at a pressure higher than atmospheric pressure from the suction port and exhausts the piston-compressed air from the exhaust port. The air pressure from the suction port is introduced from the other chamber of the cylinder, showcasing Ohwa's innovative approach to air pressure management in automotive systems.
