The racing legend has been bed-bound ever since a horrific skiiing accident in 2013.
The German driver was placed in a medically induced coma for six months after injuring his head, before being moved to a state-of-the-art medical centre at his family home on Lake Geneva.
Todt, 72, said: "I love Michael. I see his family. I wish the situation would be different.
Pointing to a picture of Schumacher clinching the first of four world titles with Ferrari, he added: "When people ask me what is my best memory, it’s this one.
"That’s Suzuka in 2000. Michael is world champion after 21 years.
"I remember saying to Michael, ‘On a professional level, things will be different for us.’
"In fact they weren’t different because we had so much passion for success that, when we got that, we wanted to win the next one. That was a time to stop for a while..
He then pointed at a second picture – this time of Schumacher, stood next to Todt's wife and son.
He said: " That’s my three darlings. Michael, Michelle and my son. I think this one [picture] was when I won the French award called Légion d’Honneur [in 2011].
"They came to the celebration. They all love each other, which is something that is also special to me."
Schumacher's family members have remained tight-lipped on his progress, offering only scant updates.
In April 2015, it was announced that Schumacher had shown "moments of consciousness and awakening".
Agent Sabine Kehm said in December 2016: "Michael's health is not a public issue, and so we will continue to make no comment in that regard."
