1. A driver state determining method, the method comprising:
obtaining, by at least one sensor, a touch sensing value corresponding to a touch input by a driver of a vehicle, and a steering torque sensing value corresponding to a steering torque input from the driver; and
determining a state of the driver as one of a hand-off state, a normal grip state, an abnormal grip state, or a hand-off determination pending state based on at least one of the touch sensing value or the steering torque sensing value,
wherein the determining of the state of the driver includes:
determining that the state of the driver is changed from the hand-off state to the normal grip state when a state before determination of the hand-off state is the abnormal grip state based on the touch sensing value, a normal grip determination condition based on the touch sensing value or the steering torque sensing value is satisfied, and a deviation of the touch sensing value is different from the deviation of the touch sensing value in the abnormal grip state by a predetermined value or more.
