Increasing road traffic safety is a major objective of governments across the world.
In particular, the European Union (EU) has set a challenging objective of halving the
number of road accident victims by 2010 [1]. Active on-board safety features offer
an approach with a high potential for achieving this target. It has been observed over
the past decades that the decrease in the number of victims is related to technological
innovations of the automotive safety, such as seatbelts, anti-lock braking system
(ABS), airbags or electronic stability programme (ESP), as shown in Fig. 1.1 (data
source: ADAC). Future generations of active safety equipment will be based on the
advanced driver assistance systems (ADAS) including e.g. adaptive-cruise control
(ACC), lane-change assistant, collision avoidance systems and parking aids. Implementation
of these systems can considerably reduce the number of road accidents
and mitigate the consequences. However, the low integration level and high cost of
the commercially available modules to date, hamper the mass volume integration
and standardization of these systems. Thus, there are research efforts, supported by
the EU [2], to develop low-cost driver assistance systems that could be suitable also
for low-budget cars.
