Title: Keiji Murashima: Innovator in Braking Torque Control Technology

Introduction

Keiji Murashima is a notable inventor based in Gotenba, Japan. He has made significant contributions to the field of braking technology, particularly with his innovative approach to braking torque control. His work has implications for vehicle safety and performance.

Latest Patents

Murashima holds a patent for a "Braking torque control apparatus and method." This invention involves a pair of shoes that are expanded by driving an electric brake motor. The friction engagement of the shoes with a drum inner peripheral surface applies a braking force to a wheel. The actual braking torque is detected by a strain sensor that measures the load on an anchor pin. Through feedback control, the electric motor is adjusted to ensure that the actual braking torque matches a target braking torque, which is determined by the brake pedal's operation. Notably, even when the actual braking torque is undetectable, such as when a vehicle is stopped, the apparatus effectively controls the braking torque.
