An electromechanical brake (EMB) system is provided. The EMB system may include: a brake rotor configured to be rotatable with a wheel of a vehicle; a brake pad assembly configured to be engageable with the brake rotor; an actuator assembly comprising an electric motor configured to mechanically move the brake pad assembly toward or away from the brake rotor via driving of a driven pulley; and an electronic control unit (ECU) coupled the actuator assembly, the ECU having a processor coupled to a memory that stores instructions that when executed by the processor causes the ECU to perform operations. The operations may include: using only a motor position of the electric motor and a clamp force exhibited when the brake pad assembly engages with the brake rotor to prevent occurrence of drag in the EMB assembly.

An electromechanical brake system includes: an actuator assembly having an electric motor configured to generate torque for moving a brake pad assembly to apply or release a brake and a driven pulley configured to transmit the torque generated from the electric motor; a parking brake assembly having a parking pawl configured to engage against the driven pulley in a parking brake applied state of a vehicle and a pawl actuator configured to move the parking pawl to engage against the driven pulley; and an electronic control unit (ECU) that is configured to control the electric motor by determining whether the electric motor should be controlled to apply the torque in a direction of releasing the brake to ensure a stable engagement between the parking pawl and the driven pulley during the parking brake applied state of the vehicle using a change in motor rotation of the electric motor.

An electromechanical brake (EMB) system is provided. The EMB system comprises: a brake rotor configured to be rotatable with a wheel of a vehicle; a brake pad assembly configured to be engageable with the brake rotor; an actuator assembly including an electric motor configured to actuate a translatable part and a rotatable part to mechanically move the brake pad assembly toward or away from the brake rotor; and an active backdrive assembly configured to release the EMB system from an on-brake state to an off-brake state without using any electrical power when the EMB system is in a powerless state following a braking operation of the vehicle.
