Decelerate moving platform at targets

Hello! I'm trying to make a moving platform move at a constant speed and then when it is near the target start to slow down, I have trying to do this with Lerp, but I'm not satisfied with the results because of two reasons: it goes way too fast between targets, and way too slow near targets.

Also, when it reaches a target it immediately boosts off in the opposite direction. What I want to achieve is for the platform to move steadily between targets, decelerate near targets, and when reaching a target start to accelerate back to the steady speed.

What is the best way for achieving this? Lerp, Smoothstep, other? Thanks!

My current solution:

 _dVeloctiy = _velocity * Time.fixedDeltaTime;
 Vector3 newPosition = Vector3.Lerp(_rigidBody.position, currentTargetPosition, _dVeloctiy.magnitude);        
 _rigidBody.MovePosition(newPosition);
 
 Vector3 dPosition = _rigidBody.position - currentTargetPosition;
 
 if (dPosition.magnitude > 0.05f)
 {
     _isTurning = false;
 }
 
 if (dPosition.magnitude < 0.05f && !_isTurning)
 {
     currentTargetPosition = (currentTargetPosition == targetPosition1 ? targetPosition2 : targetPosition1);
     _isTurning = true;
 }
