Nissan Japan has revealed a new concept car featuring multiple preventative features designed to help reduce drunk driving. Presently integrated on-board a production model Fuga sedan, the various technologies are designed to detect the driver's state of sobriety and to activate a range of preventive measures including immobilization of the vehicle.
A hi-sensitivity alcohol odor sensor is built into the transmission shift knob, which is able to detect the presence of alcohol in the perspiration of the driver's palm as he or she attempts to start driving. When the alcohol-level detected is above the pre-determined threshold, the system automatically locks the transmission, immobilizing the car. A “drunk driving” voice alert is also issued via the car navigation system. Additional alcohol odor sensors are also incorporated into the driver’s and passenger seats to detect the presence of alcohol in the air inside the vehicle cabin. When alcohol is detected, the system issues both a voice alert and a message alert on the navigation system monitor.
A camera is mounted on the instrument cluster facing the driver to monitor the driver’s face. The system is calibrated to monitor the driver's state of consciousness through the blinking of the eyes. When the system detects signs of drowsiness, a voice and message alert is triggered via the navigation system. Additionally, a seat-belt mechanism is activated which tightens around the driver to gain his or her immediate attention.
