this was realized via the MSPF that Toyota has
been building and refining.
In the future, these technologies will be applied
to the Sienna Autono-MaaS minivan being devel-
oped in the United States for use as a robotaxi,
and the MSPF will be used not only for automated
vehicles, but also for regular commercial vehicles
and logistics.
Innovation through a New Mobility
Software Platform
In this way, software has the power to promptly
turn ideas into products. The aim of Arene, the
vehicle software development platform that Toyota
and Woven Planet are focused on, is to continue
fundamentally changing the development of
software for vehicles.
The most notable characteristics of Arene are
that it absorbs the differences in vehicle hardware
specifications (abstraction) and employs hardware
abstraction layers (HAL) that enable hardware to
be controlled with universal methods. This, in turn,
enables the independent development of hardware
and software as well as the reuse of software.
Arene leverages the strengths of hardware cultivat-
ed by Toyota to achieve the development of safe,
high-quality, and advanced software.
Because increasingly complicated software
development is becoming a bottleneck for cars,
too, there is a need for a revolutionary vehicle OS
that can solve these issues. The vehicle OS will
achieve TPS in software development as well, and
we must continue to realize combinations of good
hardware and software.
For example, when developing automated
driving software, the on-board software needed
for automated driving actually makes up only
10%; the other 90% comprises various tools,
such as data processing by the machine learning
system, mounting, code review, software updates,
log analyses, and simulations. Basically, most of
the software we develop is used off-board (out-
side vehicles) or through the cloud.
Arene is used to develop frameworks for vehicle
development and development environments based
on those frameworks as well as to build ecosystems

for mobility development. Using industry-leading
software technologies, we will continue providing
privacy-conscious, secure, and safe cars.
Furthermore, application development on Arene
is also easy. Partner companies will be able to
program applications more efficiently using the
Arene's application programming interface (API,
a mechanism that can share software functions)
and software development kit (SDK), which
includes simulation environments.
In this way, development on Arene swiftly
realizes commercialization and enables users to
share the fun of providing new ideas that appeal
to customers while meeting the expectations of
worldwide partners and developers as well as the
Toyota brand's high-quality standards.
The portion of a car's value attributable to
software is growing. By internalizing the parts.
central to Toyota's future, we will strategically
ensure the strengths of our hardware and software
through internal production, compartmentalize
development undertaken with partners, and
accelerate the speed of mass production.
For these initiatives, we are building a software

development structure on a 3,000-person scale for
Toyota, Woven Planet, and Toyota Connected and
on a 18,000-person scale for the entire Group. We
are also strengthening the teams responsible for the
internal production and development of software.
Geofencing Technology Expands the
Possibilities of HEVS and PHEVS
Through connected technologies, we can contribute
to carbon neutrality by gaining a better under-
standing of the characteristics of each region in
the form of data and combining this knowledge
with realized technologies.
According to market data, in Japan, the engine is
turned off for half of all driving time in hybrid electric
vehicles, or HEVS, while for plug-in hybrid electric
vehicles, or PHEVs, the engine is turned off for as
much as 80 percent. HEVS and PHEVs can evolve
into environment-friendly vehicles to an even higher
degree by upgrading the switching control of engines
and electric motors. In other words, there is room to
expand the possibilities of both HEVS and PHEVS.
