Err, sorry but the encoders don't measure current. An absolute position encoder knows the exact speed/position of the motor. By that you can extrapolate the wheel speed position which you can just match 1:1 with the one on the other side. It won't be perfect as the reaction time of the system if wheel A breaks away and starts spinning but you don't need GPS or a downward camera to mimic a locking diff.
- mike_d 3y agoSorry I was trying to rewrite for clarity and said encoder instead of controller. If you naively emulate (as Telsa surely would) a 1:1 fully locking diff in software it will suck to drive. Electronic limited slip diffs already exist, like the Jeep FD/AD systems, which will use tire rotation sensors to determine forward momentum. Now that I think about it, the Ford is probably already doing this.
