Today’s on-vehicle electrical architectures are not
compatible with the next generation of customer expectations. The mobility solutions being designed today
have 5 obstacles to overcome -
Functional-Oriented Architectures have
overcome each new technical obstacle with a technical solution, but Service-Oriented Architectures (SOA) may be the answer for the vehicles being designed
Long design lead times for a product which will be
sold for multiple years and be used for many years - how is an automotive
electrical system to keep up with the expectations set by consumer electronics?
Through removing the interdependencies between the software and the functional
technology delivering experiences.
of adding new componentry to deliver new features, it's important to start building architecture
platforms with standardized components that can be called upon in a software-defined
vehicle, which will release software from the constraints of the vehicle’s lifecycle.
A user will not put up for long with needing to
work out which wireless connection they need to connect to. Instead, the vehicle
should be able to connect intelligently and seamlessly. Why should remote unlocking through telematics be a separate app and interaction to using
the phone as a key? Common services
being called upon in different ways allows new experiences to be added or new
componentry to be introduced without the inevitability of bugs.
A Service-Oriented Architecture can include fewer
components and allow new revenue streams without adding componentry. Emergency call (e-Call) has introduced additional
speakers and microphones in many vehicles, but with a service-oriented approach, these can be shared. The cost and weight of electrical harnesses can reduce
heavily with architectures optimized by the zone of the vehicle.
Connectivity technologies have struggled to gain
traction as standard features on vehicles, but is a day coming where
connectivity is the base assumption to provide experiences and features, such as
passive keys and navigation? Could terrestrial radio soon become an optional extra?
Opening up the supplier
All of this requires new commercial sourcing
strategies. Some suppliers are moving
away from combined hardware and software products. Will suppliers seize the opportunity to market
their software onto other’s hardware? Will
program managers accept the license costs onto their Bill of Materials for the
greater business value?
New users and new
The new generation of users is not the only group of new
customers to consider. With the move to
shared mobility, the owner of the vehicle may rarely be the user. With Service-Oriented Architectures, maintenance data can be routed through varying off-vehicle providers to ensure
continuous usage, and new revenue streams can be generated through entertainment
services. The required granularity of
offering becomes far higher than traditional markets, and can only be delivered
through a flexible, service-based, software-defined vehicle.
