Smart-unlock - how to find it?

Hello,

I just switched from Android to iOS, and i used a function known as 'smart-unlock'.

It allowed me to keep a phone unlocked when i used some bluetooth devices (ex my car) or i was on home.

I am missing that function in iOS, is there a way to turn it on or its unavaiable on that platform?
