Latest Patents

One of his latest patents is a method of controlling an electric booster for improving heterogeneous braking properties. This innovative method involves a reaction disk, a boosting body, and a pedal push rod connected to a pedal. The electric booster is subjected to braking control according to a braking map, which includes a first braking control step that generates a reaction force based on pedal effort by compressing and expanding a fluid while moving the pedal push rod. The second braking control step generates the reaction force in accordance with the pedal effort only when the reaction disk and the pedal push rod are in contact, detected by measuring the air gap between them.

Another notable patent is for an electric brake booster designed for autonomous vehicles. This system includes a body part that receives a power cylinder generating braking pressure in both autonomous and manual driving modes. It features a driving shaft that is movable in an axial direction and coupled to a piston. The design incorporates two motors that provide driving power, ensuring reliable operation whether in normal or emergency braking situations.
