How does an electronic differential in automobiles work?

Answer 1

In conventional road vehicles an electronic differential is usually a mechanical differential that uses an onboard computer to directly control and adjust the torque split and difference in wheel speed across the axle. This is acheived by electronic actuators engaing clutch packs and locking mechanisms to acheive the desired traction condition. It is esentially a computer controlled LSD and differential lock in one. This means the computer can calculate the optimal torque split and actively vary it on the fly. In electric vehicles with separate motors driving each wheel, an electronic differential is simply a computer that controls the wheel speed of the inside and outside wheels based on the steering wheel angle, to acheive the same effect as a normal mechanical differential.
