Darth Vader didn't learn he had a daughter until Return of the Jedi, when he stood before Emperor Palpatine. The Emperor's power probed Luke's mind, attempting to goad him to fall to the dark side, and he discovered Leia's existence. "Sister," the Emperor taunted.
Summary. Darth Vader's failure to recognize Leia as his daughter in Star Wars: A New Hope stems from George Lucas's late decision to make Luke and Leia siblings. Leia's Force abilities and her lack of awareness of her true identity also contributed to Vader's inability to sense their familial connection.
How does Darth Vader find out his kids are Luke and Leia?
It's not until Return of the Jedi, when Luke confronts Vader and the Emperor in the third act of the film, that the Sith Lord realizes his son is there to protect his twin sister. Luke had only recently discovered the two were siblings and, even more recently, had revealed their connection to the princess.
In the post-2014 canon universe, the story that reveals Darth Vader discovering Luke Skywalker's identity (and thus the fact that the Death Star's destroyer is his son) is issue 6 of 2015's Star Wars comics by Marvel, which takes place sometime shortly after A New Hope.

How did Palpatine know Luke was Vader's son?
Instead of being in the life suit, Vader looks like an older Anakin who never received the devastating injuries, and Padmé and Luke (who struck down Palpatine) are by his side. It's during these visions Palpatine realizes Luke - who he only knew as the Rebel who destroyed the Death Star - is Anakin's son.
Vader was hunting down the pilot who blew up the Death Star, and hired Boba Fett to find them. Boba was unable to, but he did give Vader a name: “Skywalker.” This, combined with his knowing Luke was Force-sensitive and had been trained by Obi-Wan, was what made him realize the truth.
Luke and Leia never sensed that they were twins until Return of the Jedi despite both being sensitive to the Force. Anakin Skywalker's twin children are the original Star Wars trilogy's driving force, having been separated after Padme's death.
Yes, they did. Eventually, Leia contact her good friend Pooja Naberrie to discuss her mother so they definitely knew about Padmé Amidala and the fact she was their biological mother. did luke and leia ever figure out who their mother was?
Returning to Dagobah to complete his training, an ailing Yoda told Luke the terrible truth that Vader was his father, Anakin Skywalker. Rather than destroy his father, Luke sought to bring him back into the light. At 900 years old, Yoda passed away, telling Luke that there was another Skywalker.
And during the conversation, Padme is holding her stomach and appears to have a bump, seemingly confirming she was pregnant long before Revenge of the Sith. However, she chose not to tell Anakin, presumably because he was about to go into a battle.
Ever since Return of the Jedi, Star Wars has reframed Luke and Leia's kiss as lacking real romantic intent - something Leia did solely to get a rise out of her real love interest, Han Solo.
Han Solo marries Princess Leia and they have three children: twins named Jacen and Jaina, and a younger son named Anakin. Luke reestablishes the Jedi Order, marries a non-movie (but fan favorite) redheaded Force-wielder named Mara Jade, and they have a son, Ben Skywalker (named in honor of Obi-Wan “Ben” Kenobi).
in the Dark Horse comic series star Wars Tales, which is now part of legends, it's revealed that Darth Vader did recognize C. 3PO on Cloud City. when 3PO was shot by Stormtroopers, his parts were brought before Vader. because the Imperials thought he could hold valuable.
Leia is remembering Padme but the images she sees are due to her force sensitivity, to quote Yoda in Empire "Through the Force, things you will see. Other places. The future...the past...old friends long gone." This could suggest that Leia is confusing Force visions with memories.
Given that she's the child of Anakin Skywalker, who's prophesied to be the Chosen One, the Skywalker bloodline holds a tremendous amount of power. With Leia's strong connection to the Force, it seems like the most likely solution to this inconsistency is that she's caught glimpses of her mother through Force visions.
Shmi informs Qui-Gon that Anakin has no father, leading Qui-Gon to suggest that Anakin is a product of midi-chlorians (Force-imparting microorganisms). As the film progresses, Anakin leaves Tatooine to begin his Jedi training.
Did Luke and Leia know they were siblings when they kissed?
In a medical center shortly after, Princess Leia checks on a recovering Luke, and in an effort to make Han jealous, she kisses the bedridden hero and walks away. At the time, neither Luke nor Leia knew they were siblings,...
This made Lucas realize that the prospect of Vader turning his sister to the dark side would make Luke lash out the way he did. Thus, the nascent concept of Luke and Leia being siblings provided a major emotional jolt for Vader and Skywalker's climactic fight.
The two recognize Luke's similarities to Anakin and try to prevent him from sharing his father's fate, but they let him remain Luke Skywalker instead of having him go by Luke Lars out of respect for his grandmother, Shmi Skywalker.
Here, Vader employs mind-altering drugs and subliminal suggestion in his sessions with the princess, which make Leia believe that her skin is on fire and her flesh being torn apart, causing the same reaction the real thing would. An altered version was presented in the current Star Wars canon.
More curious, however, is the fact Luke Skywalker - generally seen as the greatest Jedi Master of all - was clearly unaware of Palpatine's resurrection. That's particularly disturbing given the Emperor seduced Ben Solo to the dark side under Luke's watch.
