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



Battery

The electric car is changing the relation between automotive industry and utility

Renewablegeneration of energy

Intelligent energy distributionand transmission

Intelligent and clean mobilityWater pump station

Siemens is building its own fleet of electrical carsto gain experience in all relevant areas (4S)



„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.

Ziele des Projekts

■ Ziel 1: Reduktion der Komplexität der IKT-Architektur durch eine einheitliche, offene Basisplattform

■ Ziel 2: Unterstützung neuer, komplexer Funktionen durch die IKT-Architektur

■ Ziel 3: Plug&Play-Fähigkeit der IKT-Architektur

■ Ziel 4: Zulassungsfähigkeit der IKT-Architektur

■ Ziel 5: Aufzeigen eines Migrationspfades


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.

Development of 2 prototypes
