A recently granted patent (Publication Number: US11919494B2) outlines a method for detecting malfunctions in an electro-actuated brake apparatus of a motor vehicle. The method involves an electronic control unit and an electro-actuated brake caliper that generates a clamping force on a brake disc in response to a control signal from the electronic control unit. The detection process includes providing signals representing the real operating condition of the brake caliper, such as a control signal and a temperature signal from a temperature sensor associated with the caliper. Additionally, feedback signals, such as force or pressure feedback signals generated by sensors, are used to identify malfunctions in the system.

Furthermore, the patent describes a detailed error validation check process that involves comparing error signals with predetermined thresholds and generating stepped count signals to calculate the duration of errors beyond the thresholds. The method also includes a numerical model that simulates both linear and non-linear behaviors of the electro-actuated brake caliper to enhance malfunction detection accuracy. The target signal used in the process represents various quantities like deceleration, speed, torque, force, pressure, or position. The patent also covers an electro-actuated brake apparatus for a motor vehicle and a motor vehicle equipped with such a brake system, emphasizing the importance of efficient malfunction detection in ensuring vehicle safety and performance.
