As we’ve seen before, Nissan Japan is actively developing and employing technologies to increase the safety of their vehicles, with a particular emphasis on combating drunk driving and minimizing the impact of accidents. With those goals in mind, the company yesterday unveiled a raft of new methods aimed at making life safer for both drivers and pedestrians.
The first to see service is a modified car hood that will be fitted to certain new cars from the fall. The Pop-up Engine Hood uses a sensor in the front bumper to detect when the car has hit a pedestrian.
If it judges the impact severe enough, the system instantly opens the hood by a few centimeters. This creates a cushioning space between any pedestrian hitting the metal and the much harder engine below.
The other systems are still some way off a real-world debut and were showcased in a concept car as part of Nissan’s Vision 2015 plan to cut accidents in half by that year.
An alcohol-detection system uses sensors in the seats and gear-shift stick, combined with a transmission lock. When sufficient booze is registered in sweat from the driver’s palm by the gear stick, the car simply can’t be started until another driver tries his hand.
Should a drunk driver somehow get things moving, there’s also a driving behavior monitor that issues an audio alert when the car moves erratically, also tightening the seatbelt to gain the driver’s attention.
Lastly, a facial-recognition system uses a dashboard camera to keep tabs on the driver’s alertness. When it judges that her eyes have been closed too long, it sounds an alarm and again tightens the seatbelt.
