Title: Ryuichi Murakami: Innovator in Driving Force Control Technology
Introduction
Ryuichi Murakami is a notable inventor based in Wako, Japan. He has made significant contributions to the field of automotive technology, particularly in driving force control systems for four-wheel-drive vehicles. With a total of 6 patents to his name, Murakami's work has had a substantial impact on vehicle performance and safety.
Latest Patents
One of Murakami's latest patents is a driving force control device for four-wheel-drive vehicles. This innovative device is designed to prevent excessive understeer and oversteer in situations unintended by the driver. It achieves this by appropriately controlling the distribution of driving forces to sub-drive wheels. The device regulates the driving force to the rear wheels through a clutch, ensuring that the front wheels remain the main drive wheels while the rear wheels serve as sub-drive wheels. Additionally, the device is capable of restricting the upper limit of four-wheel drive torque based on estimated driving force and steering angle.
Another significant patent is related to a hydraulic controller for the driving force distribution device. This hydraulic controller includes a hydraulic circuit with an oil pump that supplies hydraulic fluid to a piston chamber of a clutch. The system features an opening and closing valve and an accumulator that communicates with the piston chamber. Control is performed to ensure that the piston chamber reaches a target hydraulic pressure based on specific characteristics, enhancing the efficiency and responsiveness of the driving force distribution.
