The 20-year-old picked up a trophy for her Western-style riding achievements at the prestigious Audi Generation Awards event in Munich.
Gina-Maria is already a two-time world champion and European champion and said the support of her Michael and her mother Corinna has helped her achieve success.
She said: ”I would like to thank the jury, but especially my parents for the love they give me every day.”
She revealed she used to go karting with her legendary dad but chose a different career path because “horses are better”.
The seven-time F1 champion suffered catastrophic head injuries in a skiing accident in the French Alps in December 2013 and received round-the-clock care from a team of medics based in his Swiss mansion.
He is “still fighting” four years later, according to his great friend and former Ferrari boss Jean Todt.
Mr Todt spoke after Schumacher was inducted into the F1 Hall of Fame last week.
Schumacher’s long-time manager Sabine Kehm who collected the award on his behalf.
He said: ”We miss Michael. He’s there, still fighting.
“I’m happy to have Sabine here, to run the family business.
“I wanted his son Mick to come tonight but he’s doing some testing in Spain and wife Corinna is in the States.
“A fight is going on. Michael is someone very special, someone special for motorsport.
“He’s special to me, he’s a friend.”
Schumacher’s career spanned 22 years from 1991to 2012.
He won an incredible 91 races and earned 151 podium finishes – accumulating 1,566 career points.
The German’s first win came in the 1992 Belgian Grand Prix, but his first Championship victory was in 1994, where he scraped to top spot by a single point.
Schumacher’s final race was the 2012 Brazilian Grand Prix.
The Schumacher family keep the 48-year-old’s condition a closely-guarded secret and official updates have been few and far between since the accident.
But his wife Corinna Schumacher did release a bleak statement earlier this year when she said “something serious has happened”.
The statement said: “The decision to protect his privacy from the public has been taken in Michael’s interest.
“We have made it very clear that something serious has happened.”
