Abstract: A driver's hands on/off detection system for detecting whether a driver's hands are on/off a steering wheel during driving is applied to a vehicle. When a driving assistance system is operated by a controller during driving, the driver's hands on/off detection system calculates an electronic motor driven power steering system (MDPS) torque representative value and a vehicle measurement data representative value as a representative value ratio between sensors, and divides a disturbance driving area and a normal driving area by a magnitude of the representative value ratio between sensors to perform sensor detection correction control of a hands on/off check using a disturbance torque threshold to the torque filtering value or torque-based sensing control of a hands on/off check using an upper/lower torque limit value to the torque filtering value, thereby reducing the hands on/off detection errors during driving with only a vehicle-mounted sensor without using a capacitive sensor.
