ABSTRACT:
A drunk driving detection system to be incorporated in a vehicle includes a steering wheel, a film, a pair of contact detection electrodes, an alcohol sensor, and a control circuit. The steering wheel is provided with an opening in a portion to be grasped by a driver. The film is liquid-impermeable and air-permeable, and covers the first opening. The contact detection electrodes are provided on the film. The alcohol sensor is provided in a space in communication with the opening. The control circuit is connected to the contact detection electrodes and the alcohol sensor, and measures the resistance between the contact detection electrodes. When the resistance is within a predetermined range, the control circuit determines that the driver is in contact with the film and detects an alcohol drinking condition of the driver based on the output from the alcohol sensor.
