• and
• a controller operatively connected with the input device, the sensor device, and the memory,
• wherein the at least one instruction is configured to, when executed by the controller, cause the vehicle control apparatus to
• identify state information of the tailgate using the sensor device,
• determine whether a specified condition about loss of the state information is met when a command to open and close the tailgate is received through the input device, and
• control opening and closing of the tailgate, based on an estimated RPM identified based on at least one of an environmental condition, the training data, an amount of change in current data, an amount of change in RPM, or any combination thereof, when it is determined that the specified condition is met.
