1. An electronic control steering system comprising:
a folding device driven to enable folding of a steering wheel in a driving state of a vehicle an auto folding mode;
a first power supply unit supplying power to the folding device;
a first angle sensor electrically connected to the first power supply unit;
a second power supply unit distinguished from the first power supply unit and supplying power to a second angle sensor; and
a control unit controlling steering of the vehicle through the first angle sensor or the second angle sensor,
wherein when the power supplying from the first power supply unit is interrupted, the control unit switches the auto folding mode to a manual folding mode so as to manually release the folding of the steering wheel.
