Jarno Trulli has indicated that "an announcement" about his future will be made in the coming weeks.
After the Italian veteran struggled with Team Lotus' 2011 car, he was much happier with the new power steering system that debuted in Hungary.
The 37-year-old sat out the previous German grand prix in deference to Karun Chandhok, but team boss Tony Fernandes at the time hinted that Trulli is in line for a new contract.
"I'm not worried about my future," the 2004 Monaco grand prix winner is quoted by France's autohebdo.fr. "I just want to improve myself.
"The announcement will likely be made in the coming weeks. For now, I am satisfied with my situation and concentrating on my work with the team," said Trulli.
He said his goal for the rest of the year is to enjoy the races.
"I want to enjoy what I do because it was not fun before (Hungary)," said Trulli. "Silverstone was the most difficult; I was completely lost and I wondered if it was me."
Meanwhile, according to Brazil's globoesporte.com, technical boss Mike Gascoyne said he is confident Team Lotus will drive into the midfield in 2012.
"We can focus on the parts that really make you go faster instead of doing it all again," he said.
