Improvement of vehicle reliability by managing the growing complexity of electronic architectures
Necessity to control increased complexity
Further penetration of existing safety systems (e.g. airbags, ESP)Advanced driver assistance systems (e.g. adaptive cruise control)
Increasing demand for safety Increasing need for in-car information
management
Increasing penetration of existing applications (e.g. navigation devices)More connectivity and integration of consumer electronic devices
Car of the future
Growing concern for the environment
Rising oil prices drive demand for improved fuel efficiencyCompliance with ever-higher emission standardsIncreased attractiveness of alternative propulsion concepts (e.g. hybrids)

When the pioneers of the automobile removed the horse to create the horseless carriage, they removed the intelligence as well. Now, through electronics and software, we can put the intelligence back in.

The wedge–
simple & effective
• The brake pad is moved by an electric motor via a series of rollers along a wedge-shaped slanting surface
• The rotation of the wheel automatically reinforces the effect of the wedgeA very high braking force can be produced with very little electric motor torque.

- World exhibition, Paris 1900: Ferdinand Porsche introduces his new electro vehicle.
- September 1900: Lohner- Porsche with four wheel-hubs, the first fully-operative wheel- hub motor, with a battery- weight of 1800kg.
Wheel-hub motor, front wheel steering & drive, 2,5 PS/Motor, 44 cells battery, 300 Ah, up to 80 Volt, vmax = 50 km/h (35), s = 50 km, m = 1000 kg, 1st car with 4-wheel brake, mRad = 100 kg;
1900: Allwheel drive mBat = 1800 kg
1902: Hybrid with petrol motor

–
drivers
and benefits
Benefits in comparison to conventional systemsSafety benefits (no steering column with steer-by-wire)More safety through driver assistance systemsDecrease in fuel costsCost reduction over the whole product life cycleBenefits for the environment: automobile without hydraulic liquidsPossibility of self-managed drivingMore freedom during the production: no difference between right-hand and left-hand steering due to flexible positioning of steering gear and steering column
