Rigidbody move relative position ?

Ok I want to move a rigidbody along its local axis but I can’t find the suitable command.
For rotation and torque etc we have Rigidbody.AddRelativeTorque but I can’t find the same for moving position ?

// local forward Force
rigidbody.AddForce(transform.forward * 5);
// local up Force
rigidbody.AddForce(transform.up * 5);
// local right Force
rigidbody.AddForce(transform.right * 5);

Rigidbody.AddRelativeForce.
