Abstract
A system for detecting hands-on or off of a steering wheel and a method thereof, include a direct sensor configured for detecting a hands-on sense value depending on a grip area of the steering wheel; an indirect sensor configured for detecting a hands-on sense value depending on a magnitude of a torque for rotating the steering wheel; and a controller connected to the first sensor and the second sensor and combining a direct hands-on sense value detected by the direct sensor and an indirect hands-on sense value detected by the indirect sensor to each other to determine a grip state of the steering wheel depending on a combined hands-on sense condition, and then to display and warn a result of determining the grip state of the steering wheel through an output unit.
