1. A steering apparatus for a vehicle comprising:
a first steering controller and a second steering controller configured to control a steering motor; and
a power supply configured to form a first output power source and a second output power source based on at least one of a first input power source or a second input power source through control of a power supply path,
wherein, in a case in which operation states of the first steering controller and the second steering controller are normal, the power supply forms a first output power source using the first input power source through control of the power supply path, and the first steering controller controls the steering motor based on the first output power source,
wherein the power supply includes a first DC power supply, a second DC power supply, and first to third path controllers,
wherein a first node is connected between the first path controller and the second path controller, a negative terminal of the first DC power supply and a positive terminal of the second DC power supply are connected to each other, and a second node is connected between the negative terminal of the first DC power supply and the positive terminal of the second DC power supply, and
wherein the first path controller controls a power supply path between a positive terminal of the first DC power supply and the first node, the second path controller controls a power supply path between the first node and the first steering controller, and the third path controller controls a power supply path between the second node and the second steering controller.
