摩耗量推定装置、摩耗量推定方法、及び摩耗量推定プログラム
Document Type and Number:
Japanese Patent JP7268658
Kind Code:
B2
Abstract:
A wear volume estimation device estimates a wear volume of a brake pad of a vehicle. A wear volume function expresses the wear volume as a function of a vehicle speed, a brake pressure, and a brake duration. The wear volume estimation device calculates the wear volume by using the wear volume function. Moreover, the wear volume estimation device estimates a temperature of a contact surface of the brake pad that comes in contact with a brake rotor, and updates temperature history information indicating at least a temperature history of the contact surface based on the temperature of the contact surface. The wear volume estimation device variably sets the wear volume function according to the temperature history of the contact surface indicated by the temperature history information acquired at a time of previous braking.
