Tiny kingdom chasing clean-cars lead
The Mind Sense technology research tests whether a car could effectively read brainwaves that indicate a driver is beginning to, the automaker says, “daydream or feel sleepy”.
The human brain continuously generates four or more distinct brainwaves at different frequencies.
By monitoring which type of brainwave is dominant a computer could assess whether a driver is focused, daydreaming, sleepy, or distracted.
Epple added: “If brain activity indicates a daydream or poor concentration then the steering-wheel or pedals could vibrate to raise the driver’s awareness and re-engage THIMPHU — With abundant supplies of clean electricity from hydro power, this tiny Himalayan kingdom has set itself an ambitious goal: to become a world leader in the use of electric vehicles.
In 2014, Bhutan’s prime minister introduced the country’s first two electric car models — the Nissan Leaf and Mahindra Reva — and suspended import taxes in an effort to win buyers.
Ambitious goals Prime Minister Tshering Tobgay said: “Electricity is like oil for us and is the most abundant resource. My target for Bhutan is a 70 percent reduction in fossil fuel imports by 2020.”
But the superhighway to a clean-car future has not been without bumps in this remote Buddhist nation.
More than a year after the launch, about 50 Nissan electric vehicles are plying the roads in Bhutan, and at least 22 more have been ordered, according to the local partner of Nissan, Thunder Motors.
That represents only about a tenth of one percent of the cars on Bhutan’s roads, according to government transport statistics.

Monitoring driver’s wellness Another project being tested is whether a vehicle can monitor the well-being of the driver using a medical-grade sensor in the seat of a Jaguar XJ. The sensor, originally developed for use in hospitals, has been adapted for car use and detects vibrations from the driver’s heartbeat and breathing.
Epple said: “As we develop more autonomous driving technology there will be instances when the autonomous car needs to hand control back to the driver.
“To do this safely the car will need to know if the driver is alert and well enough to take over. So our research team is looking at the potential for a range of driver monitoring technologies to give the car enough information to support this decision.
“If the car detects severe health in this nation of about 760 000 people complain that a lack of government support for a broader recharging network has limited the uptake of the otherwise well-received vehicles.
Limitation problems Misinformation about the limitations of electric car battery life and the cost of batteries, also has been a problem, they say.
Thunder Motors CEO Tashi Wangchuk said of the Leaf: “It is the most powerful and most well-received car in the country. Sales are OK by Bhutan standards.” He said his company offeres a 16-year warranty on the battery of the electric cars they sell, and that they had had no battery complaints.
But while he said he appreciated the government’s push for the country to adopt electric vehicles and its tax exemption on electric car imports, Wangchuk said driving large-scale interest would require government support for developing more charging infrastructure and land for building charging stations.
The country so far has six recharging stations in the capital, built with the support of Nissan.
Another car dealer in Bhutan’s capital, who partnered with India-based electric car dealer Mahindra Reva, said he is yet to sell even one issues, or simply that the driver is not alert, the car could take steps to ensure the driver is sufficiently focused to take over.”
Monitoring the physical health of the driver would not only detect sudden and serious illness but also allow the car to monitor his stress levels.
Predictive infotainment screen JLR hopes to reduce driver distraction by minimising the time the driver’s eyes are on the infotainment screen with a new system in testing — the predictive infotainment screen.
Epple said: “The driver will instinctively look at the infotainment screen or facis when pressing buttons to select navigation, music or the phone.
It’s intuitive. So our research is looking at how we could take a current infotainment screen and of the company’s two-door electric cars.
That appears to be because Nissan offered a discount of almost 50 percent on the first 77 cars sold in Bhutan. Those cars sold for the equivalent of R181 304 each. Once the offer ends they will sell for the equivalent of R345 520, dealers said.
The Mahindra Reva, on the other hand, costs the equivalent of R201 541.
No sales Ugen Tsechup who runs Zimdra Automobiles, one of Bhutan’s most popular car dealers, said: “Mahindra Reva is doing badly and we have not sold any Reva cars on a commercial scale.
“But once the Leaf’s subsidy is removed, Mahindra Reva can be an option too.”
Prime Minister Tshering Tobgay told the Thomson Reuters Foundation that “he is committed to see Bhutan take sustainable transport very seriously” and had, for instance, raised taxes on traditional vehicles to make it more attractive for people to buy electric vehicles.
“The government has done its part and left it to the private sector to take it forward,” he said.
But he also said the government is studying the viability of introducing electric buses and
Haptic accelerator Haptics could also be used to communicate with the driver through the accelerator pedal to increase the speed of response and to ensure the correct action is taken.
To create these sensations in the accelerator pedal, an actuator is fitted to the pedal and allows for vibrations or pulses to be passed through the foot of the driver.
The technology also uses a torque motor, which can create resistance in the pedal feel.
This resistance could be used to notify the driver that they are pushing the accelerator through a speed limit.
Alternatively, if you were crawling along in traffic a timely warning through the accelerator could prevent you bumping into the car in front.
Epple added: “To avoid saturating the driver with more visuals and sounds, which could overload and distract them, we are exploring other ways for the car to communicate with the driver.
With our haptic pedals research we are investigating non-visual ways to communicate which would enable the driver to make smarter and faster decisions and reduce the potential for crashes.” — Wheels24 taxis.
One aim, Tobgay said, is to cut fossil fuel imports from India and harness more of Bhutan’s own green power as part of its effort to move to zero net greenhouse gas emissions by 2020.
Money saver Some buyers of the electric cars say they’ve been happy with the switch.
Yeshey Tshering, a taxi driver who bought his first electric car four months ago, said he previously spent the equivalent of R5 000 on fuel every month and R600 on engine oil but now saves most of that.
Tshering said: “I do not have to pay for fuel, emission tests and maintenance. I pay the equivalent of R200 a month on electricity bills (for recharging). The car is total value for money.”
His only concern, he said, was whether a better network of charging stations would be created.
“Once they are installed at different districts, the market ought to get better,” Tshering said.
Bhutan has seen a surge in car use and ownership since a ban on import of cars since July 2012 was lifted in July 2014. — Reuters.
