The various technologies are designed to detect the driver’s state of sobriety and to activate a range of preventive measures including immobilisation of the vehicle.
Alcohol Odour Sensors
1) A hi-sensitivity alcohol odour 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, immobilising the car. A “drink-driving” voice alert is also issued via the car navigation system.
2) Additional alcohol odour 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.
Facial Monitoring System
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 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.

By GlobalDataDriving Behaviour
By constantly monitoring the operational behaviour of the vehicle (e.g. sensing if the vehicle is drifting out of its driving lane), the system can identify signs of inattentiveness or distraction in the driver. When the system detects such behaviour, voice and message alerts are issued via the navigation system. The seat-belt alert mechanism is also activated, tightening around the driver to gain immediate attention.
The concept car was developed as an exploratory platform to showcase breakthrough technologies that could potentially be applied to future production cars, part of an ongoing programme from Nissan contributing towards the prevention of drink-driving.
Nissan has already launched and is developing several initiatives to help prevent drunk-driving. In June, the company introduced the “drink-driving” message alert on its navigation system.
In July, Nissan also began testing of a new on-board breathalyser system in cooperation with several local government authorities, where an interlock mechanism will immobilise the vehicle if the driver’s breath indicates the presence of alcohol above a specified level.
