MUMBAI, India, June 24 -- Intellectual Property India has published a patent application (202617063157 A) filed by Mitsubishi Electric Corporation on May 19, 2026, for Estimation Device, Brake Control Device, And Estimation Method.
Inventors include Tsugoshi Ryohei; and Morimoto Yoshihiro.
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: An estimation device (18) estimates an amount of wear of a friction material of a mechanical brake device (30) comprising: a pressing mechanism that generates a mechanical brake force by pressing, by means of a rotational force of a motor (31), the friction material against a rotating body that rotates when a vehicle is traveling; and a gap adjustment mechanism that performs a mechanical operation for bringing the friction material close to the rotating body so as to maintain a gap between the friction material and the rotating body within a target range, the gap existing in a state in which the pressing operation of the pressing mechanism is stopped. The estimation device (18) includes a determination unit (19) and an estimation unit (20). The determination unit (19) determines the presence or absence of the mechanical operation of the gap adjustment mechanism on the basis of a starting rotation amount, which is a rotation amount of the motor (31) from when the motor (31) starts rotating until when the friction material contacts the rotating body. The estimation unit (20) estimates an amount of wear of the friction material on the basis of the number of times that the mechanical operation of the gap adjustment mechanism has been performed.
