  • Patent number: 12227155
    Abstract: A brake device for a vehicle includes a fluid supply portion that supplies a fluid to a wheel cylinder utilizing the fluid in a reservoir and is configured such that a piston presses brake pads against a disc rotor to apply a braking force to a wheel. The brake device includes: a fluid level sensor configured to measure a value of a fluid level in the reservoir and a controller including one or more processors and configured to: estimate a wear amount of the brake pads based on a result of measurement by the fluid level sensor; estimate a heat generation amount of the brake pads based on the result of measurement; and determine whether a fluid leakage is occurring based on i) an amount of change in the fluid level that is based on the result of the measurement, ii) the wear amount, and iii) the heat generation amount.
