Brain-to-Vehicle – Technology Redefines Future of Driving.

Nissan (YOKOHAMA, Japan) unveiled research that will enable vehicles to interpret signals from the driver’s brain, redefining how people interact with their cars. The company’s Brain-to-Vehicle, or B2V, technology promises to speed up reaction times for drivers and will lead to cars that keep adapting to make driving more enjoyable.

Nissan will demonstrate capabilities of this exclusive technology at the CES 2018 trade show (Jan 9-12, 2018) in Las Vegas. B2V is the latest development in Nissan Intelligent Mobility, the company’s vision for transforming how cars are driven, powered and integrated into society.

“When most people think about autonomous driving, they have a very impersonal vision of the future, where humans relinquish control to the machines. Yet B2V technology does the opposite, by using signals from their own brain to make the drive even more exciting and enjoyable,” said Nissan Executive Vice President Daniele Schillaci. “Through Nissan Intelligent Mobility, we are moving people to a better world by delivering more autonomy, more electrification and more connectivity.”

B2V how works?

This breakthrough from Nissan is the result of research into using brain decoding technology to predict a driver’s actions and detect discomfort:

Predict: By catching signs that the driver’s brain is about to initiate a movement – such as turning the steering wheel or pushing the accelerator pedal – driver assist technologies can begin the action more quickly. This can improve reaction times and enhance manual driving.

Detect: By detecting and evaluating driver discomfort, artificial intelligence can change the driving configuration or driving style when in autonomous mode.

Other possible uses include adjusting the vehicle’s internal environment, said Dr. Lucian Gheorghe, senior innovation researcher at the Nissan Research Center in Japan, who’s leading the B2V research. For example, the technology can use augmented reality to adjust what the driver sees and create a more relaxing environment.

“The potential applications of the technology are incredible,” Gheorghe said. “This research will be a catalyst for more Nissan innovation inside our vehicles in the years to come.”

Nissan’s B2V technology is the world’s first system of its kind. The driver wears a device that measures brain wave activity, which is then analyzed by autonomous systems. By anticipating intended movement, the systems can take actions – such as turning the steering wheel or slowing the car – 0.2 to 0.5 seconds faster than the driver, while remaining largely imperceptible.

The main way to measure these electrical patterns in a person’s brain is with a method called electroencephalography, or EEG. This technology requires the use of a headset dotted with electrodes that either press directly against a person’s scalp or come as close as possible.

Nissan is calling this an “exclusive” technology, but it’s not the first to explore the idea of bringing brain waves into the driving experience: Renault experimented with using EEG tech to control a car in 2016, Jaguar announced in 2015 that it was working on a way to measure a driver’s brain waves in order to make sure they were paying attention to the road, and researchers tested similar ideas as early as 2011.

Many other questions remain. How would the brain-to-vehicle system handle a situation where a driver makes one quick decision, but then immediately changes their mind, or encounters a new obstacle? At what point would the car’s own autonomous system, using the data it’s gathered through cameras or LiDAR and radar, override the brain computer interface — or should it? Will this tech even be ready before fully autonomous cars hit the road?

We’ll hopefully start getting some answers next week at CES (Jan 9-12, 2018).
