`ABSTRACT
`
`INTRODUCTION
`
`This paper and presentation
`will describe how one companyis ad-
`dressing the convergence of entertain-
`ment,
`information and communications
`for tomorrow's automobiles.
`The ap-
`proach presents a framework for incor-
`porating diverse technologies
`in cost
`effective and efficient ways to provide for
`both flexibility and future growth.
`It
`offers a paradigm for integrating best-in-
`class technologies from third parties into
`multimedia
`systems
`that meet
`fast-
`changing customer demands.
`
`The approach recognizes that
`automotive customers’ expectations for
`features and functions are increasingly
`driven by computing and telecommuni-
`cationscapabilities that they experience
`outside of their cars. Future in-vehicle
`multimedia systems will be based on
`combinations of leading edge technolo-
`gies
`involving computers,
`cellular or
`satellite communications, car radio and
`car navigation product technologies.
`
`The paper proposes an open
`systems approach to multimedia sys-
`
`tomorrow's
`and
`today’s
`In
`multimedia word, automotive electronics
`suppliers are confronted with a variety of
`daunting challenges including technolo-
`gies that are emerging from outside the
`automotive industry. These technologies
`are more diverse and have shorter life
`cycles than almost anything in the tradi-
`tional automotive industry’s experience.
`Automotive
`electronic
`suppliers must
`develop systems and architectures that
`bridge the gap betweenthelife cycles of
`typical
`consumer products
`that
`are
`measured in 6 to 18 months and vehicle
`lifecycles that can last more than ten
`(10) years including development times
`of 18 to 36 months.
`
`It is interesting to compare the
`market penetration rate for cars versus
`those of various electronics products as
`shownin Figure 1.

`TOP LEVEL ARCHITECTURE
`
`For VDO, the underlying struc-
`ture on which to build future multimedia
`solutions is a hardware and software
`architecture that we have called Top
`Level Architecture (“TLA”).
`TLA is an
`open, scalable, upgradeable and modu-

`that
`integrates
`standard, proprietary and third party
`products and technologies.

`connectivity framework that allows us to
`focus our expertise and to leverage our
`resources without
`inventing the latest
`technologies that are created outside the
`automotive market.
`Schematically, this
`is illustrated in Figure 4.

`
`In this example, TLA allows for integra-
`tion of multiple phone and route planning
`services. TLA uses a “services broker’
`to control
`the interaction between the
`Services and Presentations. This allows
`users to locate and connect to services
`on an as-needed basis. Moreover,
`additional Services can be installed on
`the platform, register themselves for use
`and connect with other services that are
`required. This approach can readily be
`extended to such other third-party en-
`tertainment applications as MP3, video,
`and so forth.

`
`ABSTRACT
`
`The past, current and future role of electronics in
`reducing accidents, crash severity and crash notification
`is discussed. A holistic approach that ties pre-crash,
`crash and post-crash factors in enhancing automotive
`safety is examined and the growing role of electronicsin
`affecting the three factors is discussed.
`Electronic
`technology has already entered the automotive safety
`arena,andits utilization in the future is expected to grow
`rapidly towards the goal of safer roadway environment.
`
`INTRODUCTION
`
`The use of electronic componentry in automobiles has
`been increasing steadily since the mid-1980's.
`In
`responseto societal needsfor fuel efficiency and cleaner
`environment, the vast majority of powertrains are now
`controlled by electronic components due to their high
`reliability
`and
`miniaturization
`of
`sensors.
`Microprocessors are becoming faster and sophisticated
`algorithms have been developed to control powertrain
`functions.
`Electronics has moved in to the field of
`automotive safety with application in Anti-lock Braking
`System and Enhanced Stability Protection Systems.
`Early airbag systems have used mechanical sensing
`systems
`for
`crash
`severity
`prediction,
`but
`the
`diagnostics, display and design have beenelectronically
`controlled. With further advances in micro-machining
`and micro-processor technologies, the role of electronics
`in automotive safety has increased substantially in the
`mid-1990's, and is expected to grow exponentially in the
`future.
`
`CURRENT PERSPECTIVE
`
`PRE-CRASH
`
`Electronic sensing technology is already being used to
`enable anti-lock braking system and enhanced stability
`systems. The usage of these technologies in mass
`production continue to increase and are expected to
`reduce accidents in the future. Seat belt sensors are
`now being used to detect belted status of occupants to
`change
`airbag deployment
`thresholds.
`Pre-crash
`sensing of seat position is currently being used as a
`surrogate for occupant size and proximity to the airbag.
`Based onthe pre-crash information, airbag deployments
`are being controlled.
`
`into
`translate
`rates
`increased belt wearing
`Since
`improved safety of occupants, "belt minders" have been
`introduced in mass production. Although the real world
`effectiveness of this intervention is too soon to estimate,
`the effect is certainly expected to be positive.
`
`CRASH PHASE
`
`Crash severity sensing in vehicles involved in crashesis
`evolving rapidly from mechanical to electronic sensing.
`Electronic crash severity sensing is used in front
`impacts, side impacts and rollover prediction.
`In frontal
