Abstract:
According to aspects of the present disclosure, a vehicle includes a braking system, at least one controller, and at least one memory. The braking system includes a brake fluid therein and a brake pedal. The at least one memory stores instructions that, when executed by the at least one controller, are configured to: determine, via a boiling-point module, a boiling point of a brake fluid within a braking system of a vehicle; determine, via a fluidic-properties module, fluidic properties of the brake fluid; determine, via a corrosion-inhibitor module, an amount of corrosion inhibitors within the brake fluid; determine, via a reserve-alkalinity module, a reserve alkalinity of the brake fluid; estimate, a brake-fluid life module, a remaining effective life of the brake fluid using the boiling point, the fluidic properties, the amount of corrosion inhibitors, and the reserve alkalinity; and adjust a response curve of the braking system.
