Abstract: A vehicle electronic system including a parking brake equipment, comprising a brake element (2) including either a brake pad or a brake shoe, said brake element (2) including an electrical circuit equipped with one or more sensors (3, 4, 5) for real-time detection of signals relating to temperatures and/or to normal forces and/or to shear forces and having electrical terminals arranged in a zone for collecting the signals from the brake element, said vehicle electronic parking brake system further comprising an actuator (8) of the brake element (2), a controller (7) delivering a braking force command to the actuator (8), and regulating means (9, 10) driving the controller (7), wherein the regulating means (9, 10) include a closed regulating loop of the braking force including a reference braking force generator (10), said closed regulating loop of the braking force being communicating with said sensors (3, 4, 5) to acquire at least one of temperatures and/or normal forces and/or shear forces measurements.

Abstract: Methods and devices for estimating a residual torque between the braked (e.g., brake disk or drum) and braking elements (e.g., support plate or friction block) of a vehicle based on acquired and reference temperatures, where the reference temperature can be calculated using an N-dimensional calculation model with an N-dimensional vector of input variables, and where said N-dimensional calculation model can be an analytical or experimental characterization of the thermal behavior of the brake.
