Robust vehicle securement techniques for vehicle-to-everything power generation

A securement method for a vehicle for vehicle-to-everything (V2X) power generation, the securement method comprising:

• receiving, by a controller of the vehicle and from a shifter associated with a transmission of the vehicle, a requested state for the transmission from a park state where a park pawl of the vehicle is engaged and one or more non-park states where the park pawl is disengaged, wherein the park pawl is configured to engage/disengage to selectively lock the transmission in the park state;
• detecting, by the controller, for a key fob associated with the vehicle;
• detecting, by the controller and via a user interface device of the vehicle, a lock request associated with a power generation mode during which an electrified powertrain of the vehicle is configured to operate in a generator mode and output electrical power;
• in response to the lock request, commanding, by the controller, an actuator to physically lock the shifter while the transmission is in the park state and the park pawl is engaged;
• and
• while operating in the vehicle in the generator mode:
• when the key fob is not detected:
• keeping, by the controller, the park pawl engaged in response to a requested non-park state from the shifter caused by a forced manual override or breakage of the actuator by an unauthorized operator, and
• keeping, by the controller, the vehicle immobilized in response to an actuation of a manual park release system configured to disengage the park pawl;
• and
• when the key fob is detected, terminating, by the controller, the generator mode of the vehicle, disengaging, by the controller, the park pawl in response to the requested non-park state from the shifter, and enabling, by the controller, a drive mode of the vehicle,
• wherein a presence of the key fob is continuously monitored for through controller area network (CAN) signals instead of multiple key fob search requests thereby avoiding draining of a low voltage battery of the key fob.
