Abstract: A cable-coupled by-wire control of a vehicle control function traditionally activated by driver manipulation of a pedal is achieved though the agency of a Bowden cable having a first end fastened to the driver pedal, and a second end coupled to a by-wire actuator. The by-wire actuator has a pulley on which the second end of the cable is fastened, an electric motor coupled to the pulley to permit by-wire activation of the vehicle control function by rotation of the pulley in a direction to pull on the pedal with the cable. A relief chamber of the actuator radially outboard of the pulley accommodates slack in the cable within the actuator caused by driver manipulation of the pedal during by-wire activation of the control function.
