12 In-Car Devices to Watch Drivers
Don’t look now, but your car is
watching you
|
MADISON, Wis.—Automakers know that drivers can’t
be trusted. Drivers get tired, they get sleepy and, more often than not,
their attention wanders.
Auto makers and the insurance industry have come to regard driver monitoring
— how the driver drives — as the key to making cars safer for the driver
himself and for the rest of us on the road.
But technologies to monitor drivers have taken on a whole new meaning in
recent years, as car companies accelerate their efforts to develop
autonomous cars.
Why?
Once car companies start to roll out automated driving features, they realize they will have to deal with a new issue — namely, the driver’s attention.
Especially in the scenario of “Level 3 autonomous driving“ (which NHTSA
defines as “Limited Self-Driving Automation”), there is an implied need to
monitor the driver to ensure that he or she is available to take control
when the car transitions from automated to manual driving.
When the car is doing all the work, how do you keep “drivers” interested in
driving? Car companies now know that drivers can’t be assumed to be always
engaged in driving or always ready to intervene when required by the vehicle
or the situation.
Automaker liability
Driver monitoring is no longer a nice-to-have feature. In the era of
self-driving cars, it becomes a must-have technology, because drivers, some
of the time, are still going to be required behind the steering wheel.
“The driver monitoring business comes down to auto maker liability,” said
Roger Lanctot, associate director in the global automotive practice at
Strategy Analytics. “The car maker needs to ensure the driver is paying
attention when they need to take control, or the car must move to the side
of the road.”
In essence, when driving a car equipped with an in-cabin camera, drivers
will be trading privacy for safety.
Lanctot added, “What is not crystal clear at this point is a) whether
drivers will tolerate being monitored (as the cost of having an automated
car) or b) whether it will be possible to turn these systems off.”
The car industry’s demand to monitor drivers has already given rise to
several startups focused on driver monitoring systems. It has also led to
innovations that range from software algorithms to dedicated hardware.
The car industry has already fostered some major advances in the
technologies used for driver monitoring systems.
Dominique Bonte, managing director and vice president, B2B, at ABI
Research told EE Times, “The main change has been the shift from traditional
technologies based on steering wheel sensors and telematics towards in-ward
facing cameras for eye tracking and facial recognition.”
He explained that the main benefit of camera technology is the flexibility
to handle a large number of use cases.
Use cases include:
Technology transition
While acknowledging that the main driver-monitoring technology currently
deployed is based on cameras, Bonte said other technologies will be
emerging.
He predicted, “In the future biometric sensors for measuring health
parameters such as heart rate, body temperature and humidity will become
more important — either through embedded sensors in the seat or steering
wheel or through wearable devices such as smartwatches.”
He added, “Brain-wave monitoring is also being considered by car brands.”
Asked about key technology suppliers of driver monitoring systems, both ABI
Research and IHS Automotive analysts listed Aisin, Tobii, Smart Eye and
Seeing Machines as major players.
EE Times has put together a list of 12 designers and implementers of driver
monitoring systems. Some have products close to commercialization while
others are still in the R&D phase.
