Looks Kantian to me.
Here are some resources for you to look into it further.
(iii) Autonomy plays a key role in Kant’s deontological ethics.
We have already seen this in the way in which Kant grounds human dignity in autonomy. But autonomy plays a further (and closely related) normative role for Kant. It is often said that Kant held that the Categorical Imperative can be expressed in three closely related formulas: the Formula of Universal Law, the Formula of Humanity, and the Formula of the Kingdom of Ends. It has also been claimed, however, that Kant defended a fourth formula, which may be called the Formula of Autonomy. Although Kant did not state this formula explicitly, it has been argued that it can be plausibly derived from his description of the Categorical Imperative as “the idea of the will of every rational being as a will that legislates universal law.” The corresponding Formula of Autonomy could then be expressed as an imperative in this way: act so that the maxims you will could be the legislation of universal law. According to this formula, we should act according to principles that express the autonomy of the will. This formulation is important, firstly because it suggests that Kant conceived autonomy as a normative principle (and not merely as a condition of the will that makes morality possible), and secondly because it further reinforces Kant’s claim that humans, as autonomous law-givers, are the source of the universal law that guarantees their freedom and hence marks them out as possessing inherent dignity (see Reath 2006).
