Abstract: A soft-park control system to control vehicle movement during parking of a vehicle includes a transmission and one or more brake assemblies. The transmission includes a parking pawl that mechanically engages a notch in a parking gear. The brake assembly includes an electro-mechanical actuator configured to apply a variable brake force to a wheel coupled to a brake assembly based on an existing brake pressure. The soft-park control system further includes an electronic control unit having a soft-park hardware controller in electrical communication with the electro-mechanical actuator. The electronic brake control unit outputs a brake pressure signal that adjusts the existing brake pressure so as to control a rate at which the parking pawl engages the notch.
