24-year-old Ericsson has struggled throughout his maiden campaign, being comprehensively beaten by team-mate Kamui Kobayashi while also suffering a number of accidents.
However, with six rounds remaining he believes 2014 has been acceptable and plans to remain in the sport for 2015 and beyond.
"The debut season in F1 is obviously very tough but it's been okay," Ericsson told Reuters.
"The aim for me is to stay in Formula 1 for many years and that's what we’re working at doing at the moment."
Ericsson added that he was not being distracted by the uncertainty over his team-mate. Kobayashi was dropped for Lotterer in Belgium only to return in Italy. However, the team are now believed to want Formula Renault 3.5 title contender Roberto Merhi to replace him as soon as he qualifies for a superlicence.
"To be honest, when you're in the car and preparing for race weekends you're so focused on that you don't really think about it," he said.
"It's not been something that has influenced me but obviously now we have the new owners that have come in and they've been pushing really hard to continue developing the car, so that's been very positive. I think we're in a good trend."
Despite struggling in comparison to his team-mates, Ericsson has scored Caterham's best result of 2014 thanks to an 11th-place finish at Monaco.
