So, how did they deal with unsprung weight? I suppose, up to a point,
stiffer springs and shocks would help. At some point, they would just
add too much bounce to the car as a whole, though. Maybe their motor is
light enough that the added battery weight compensated just enough to
make stiffer springs work. Would be interesting to know.

]
Elaphe Propulsion Technologies [
http://in-wheel.com/
] recently introduced modular platforms for autonomous vehicles. The
Slovenia-based company has manufactured electric in-wheel propulsion
systems
since 2003.
Maros Sefcovic, vice president of the European Commission’s Energy
Union,
praised Elaphe’s propulsion design platform for its simplicity,
efficiency,
and high-torque performance. Sefcovic called the Elaphe design the
“platform for the next generation of mobility.”
Elaphe’s 15-year focus on highly efficient, ultra-low weight,
electromagnetic in-wheel motors led to two developments significant
today:
creative torque-vectoring solutions and a modular, plug-and-play
platform
for autonomous vehicles.
Torque vectoring technology varies the amount of power between wheels
in
two-wheel drive and four-wheel drive vehicles. Originally used in race
cars,
torque vectoring helps acceleration and handling by improving traction.
Electronic controllers in each wheel work in concert to apply power
where it
does the most good. Unless you are intentionally drifting a car, for
example, the goal with torque vectoring is to keep the car under
control, on
the road, and traveling in the desired direction with the least tire
slippage possible.
Electric cars such as Tesla’s Model S accelerate extraordinarily
quickly
because electric motors produce maximum torque from a standstill.
Internal
combustion engines (ICEs) need to rev up to reach maximum torque.
Because
there’s no wait for torque buildup with EVs, electric car designers can
take
greater advantage of torque-vectoring than with ICE-powered vehicles.
Elaphe builds electric motors in each wheel, complete with independent
cooling systems. With four motors, near-instant torque is available for
each
wheel. Each wheel also has a standard disc or drum brake plus a power
electronics unit.
A vehicle propulsion control unit can interface with an autonomous
driving
controller unit or get input from a human driver, depending on vehicle
design. A combined power distribution and management module coordinates
the
power sent to the motor in each wheel.
Elaphe manufactures each of the components in its modular autonomous
vehicle
platform and also develops and provides components for other
manufacturers.
Elaphe’s future focus is to provide vehicle designers some or all of
the
parts for mobility platforms with which designers can create a wide
range of
transportation products. Elaphe’s direct-drive in-wheel motors are
adaptable
for automotive manufacturers who plan to build self-driving cars with
new
powertrain design concepts, rather than by adding newer components to
traditional vehicles.
