Global Megatrends strongly influencethe future of mobility
Urbanization Demographic changeClimate change
Utilize sustainable power source for
mobility
Spend less energy in total for mobility
Support people to get from A to B
hassle free
Use intermodality to handle peoples
demand for mobility
Safely extend mobility of elderly
people
“Zero Emission”by EV
“Intelligent mobility”through, telematics and Smart Grid integration
“Zero Accidents”by stability control and
predictive ADAS systems
Will lead to new kind of mobility concepts

“Zero Emission” can be achieved with electric vehicles only
E-Mobility is the most efficient way to become independent from fossil fuels in road transportation,
because
Sustainable power can be produced in many ways, but producing liquid fuel in a sustainable way is not possible even for today’s fleets.
Furthermore, E-Mobility will support the expansion of renewable energy, if the car’s battery is used as stationary storage (bidirectional)

“Intelligent Mobility” means that the vehicle becomes a part of a greater service network
Driven by socio economic trends, most of future business models will be based on new services where the electric vehicle is one player between many others:
Seamless Mobility
Optimization of traffic flow
Stabilizing the power grid
Location Based Services

„Zero Accidents“ becomes attractive when combining safety with comfort only
Advanced Driver Assistance Systemsare the major pillar for getting near to“Zero Accidents” wanted by legislators and insurances.
But
“Zero Accidents“ in itself is nothing a customer wants to spend too much money for, because it is not very exciting.
Solution
But ADAS is the foundation of “Always supported” and that can be experienced by the driver as a valuable add on.

To discover the full potential of electric vehicles a new E/E architecture is mandatory
Less controllerLikely less copperLess different connectorsPlug & play capable
*Symbolic pictures
Get rid of position oriented partitioningWell defined information flowHierarchical decision makingPlug & play capable
Easier integration of new functions
Advanced variant management
Shorter development time

Im "RACE“-Projekt werden ein evolutionärer undein revolutionärer Fahrzeugprototyp aufgebaut
Reduce the complexity of the ICT
architecture
Proof functionality
of ICT architecture+
“Migration / Evolution Car”• The car is based on a standard OEM vehicle.• One block of functions (e.g. lateral dynamics,
longitudinal dynamics, energy mgmt.) is realized with the new System Architecture.
• All other functions are still based on the conservative architecture.
• New System Architecture and standard Architecture are connected via gateway.
“Revolution Car”• The car is based on a new kind of car.• All functions (e.g. accelerate, decelarate, energy mgmt., HMI) is
realized with the new System Architecture.• No integration of functions which are based on conservative
architecture.• Single hardware devices might be connected via gateway• The goal is pure Drive-by-Wire with redundant electronics.
All standard functions of a car are realized. But just a selected amount of functions is based on the new System Architecture.
All functions are based on the new System Architecture. But just a small amount of possible functions is realized.
