Latest Patents

Among Kawabata's latest innovations is the "Hydraulic supply arrangement for use with active automotive suspension." This invention addresses the challenge of managing the load on a vehicle's prime mover by implementing a pump control arrangement that adjusts based on the automotive vehicle's speed. The system inhibits pump output beyond a basic estimate when the vehicle speed is below a predetermined level. Furthermore, if the speed falls while the pump output exceeds the basic estimate, the operating mode is maintained temporarily before reverting to the basic estimate level. Another notable patent is also titled "Hydraulic supply arrangement for use with active automotive suspension," which aims to reduce the pump load on the prime mover, consequently improving fuel consumption. This invention modifies the operating mode of a variable displacement pump according to a consumption estimate influenced by engine speed and lateral acceleration data. The consumption estimate is adjusted based on sensor inputs that reflect the work being done by the servo and is dependent on vehicle speed and lateral acceleration.
