Abstract: A vehicle braking system including a brake pedal in communication with a wheel brake, a brake actuation system, a braking system controller, an on-board driver communication system, and a controller is described. Parameters associated with a braking request, a brake actuation command and vehicle operation are monitored during each braking event, and segmented the into parameters associated with a static portion of the braking event and parameters associated with a dynamic portion of each braking event, evaluate the parameters associated with the static portion of the braking event and evaluate the parameters associated with the dynamic portion of the braking event, and assess a state of health of the braking system based upon the evaluation of the parameters. The assessment of the state of health of the braking system is communicated to a vehicle driver via the on-board driver communication system.

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.
