1. A vehicle control system comprising:
a braking system operably coupled to a wheel assembly to apply braking force to the wheel assembly when actuated responsive to operation of a brake pedal;
a propulsion system operably coupled to the wheel assembly to apply positive torque for propulsion responsive to operation of an accelerator pedal;
a gear selector operably coupled to the brake system and the propulsion system to select an operating state of the vehicle when the gear selector is in an unfaulted state, the operating state being a selected one of a group of states including a park state and a drive state, the braking system applying a holding force to the wheel assembly in the park state and the propulsion system enabling application of the positive torque for propulsion in the drive state; and
a park status backup controller operably coupled to the brake pedal to detect actuation of the brake pedal, and operably coupled to the gear selector to receive information indicative of a fault state of the gear selector,
wherein, in response to receiving an activation pattern during the fault state, the park status backup controller generates an operating state change instruction.
