System Benefits
Electric Power Steering (EPS) improves
fuel eiciency by approximately 3%
while having a positive eect on car
handling, the overall driving experience
and comfort
It combines a compact design with
reduced mounting costs
EPS can be adapted via soware to suit
diverse car models as well as dedicated
driving modes
EPS is the steering technology
needed to enable advanced driver
assistance systems such as side-wind
compensation, lane assist/keeping and
parking assistance systems
Infineon has over ten years of experience
in this exciting application and provides
the full range of ICs, from sensors to
microcontrollers, and from bridge
drivers to world-class MOSFETs
System Benefits
The electric parking brake provides
drivers with many more comfort
and convenience features than the
standard mechanical system
Hill hold, launch control, roll-away
prevention are possible
These convenience features are in
many cases safety-relevant and
therefore should be implemented
using safety-compliant hardware
(according ISO 26262)
