System and method for controlling parking brake in an electromechanical brake (emb) assembly

Abstract

An electromechanical brake (EMB) assembly includes: a brake pad assembly; an electric motor mechanically connected to the brake pad assembly via at least one gear having teeth to apply a parking brake to place the EMB assembly in a parking brake enabled state; a parking lock mechanism that includes a parking pawl that prevents release of the brake pad assembly from the parking brake enabled state; and a controller electrically connected to the electric motor and configured to control the electric motor to re-apply the parking brake in response to the controller determining that the parking pawl will be or is already engaged with the teeth of the at least one gear in an unstable parking brake state.

Dependencies are inferred from the claim text.
