Latest Patents

One of his latest inventions is a braking control device for vehicles. This device utilizes pressure to feed braking fluid from a master cylinder to a wheel cylinder, generating braking force in the wheel. It features an input rod, an output rod, first and second electric motors, and first and second racks that form a differential mechanism. The unique aspect of this invention is that the operation power of the input rod and the displacement of the output rod can be controlled independently by adjusting the outputs of the electric motors. Additionally, the second rack's backward movement is limited by two stoppers, ensuring precise control.

Another innovative braking control device developed by Bull includes a differential mechanism, a first electric motor that provides assisting force in the braking operation, and a second electric motor that adjusts the output rod shift of the differential mechanism. The controller for this device manages both electric motors based on an assistance map and a displacement map, allowing for dynamic adjustments to the braking system. When changes are made to the displacement map, the assistance map is also corrected accordingly, enhancing the overall performance of the braking system.
