Methods and systems of braking a vehicle. One method includes determining, with a first electronic processor, whether the vehicle is in a collision state or a non-collision state. The method also includes determining, with the first electronic processor, an amount of deceleration needed to avoid a collision with a first object. The method also includes determining, with a second electronic processor, whether an electronic parking brake has been activated. Responsive to determining that the electronic parking brake is activated and the vehicle is in the collision state, the method also includes controlling, with the second electronic processor, the electronic parking brake to provide an amount of deceleration of the vehicle based on the amount of deceleration needed to avoid a collision with a first object and a predetermined maximum amount of deceleration of the electronic parking brake.
