Next generation cars embed intelligent assessment of car driving safety
through innovative solutions often based on usage of artificial intelligence.
The safety driving monitoring can be carried out using several methodologies
widely treated in scientific literature. In this context, the author proposes
an innovative approach that uses ad-hoc bio-sensing system suitable to
reconstruct the physio-based attentional status of the car driver. To
reconstruct the car driver physiological status, the author proposed the use of
a bio-sensing probe consisting of a coupled LEDs at Near infrared (NiR)
spectrum with a photodetector. This probe placed over the monitored subject
allows to detect a physiological signal called PhotoPlethysmoGraphy (PPG). The
PPG signal formation is regulated by the change in oxygenated and
non-oxygenated hemoglobin concentration in the monitored subject bloodstream
which will be directly connected to cardiac activity in turn regulated by the
Autonomic Nervous System (ANS) that characterizes the subject's attention
level. This so designed car driver drowsiness monitoring will be combined with
further driving safety assessment based on correlated intelligent driving
scenario understanding.

在使用人工智能的基础上，下一代汽车通过创新解决方案嵌入了对驾驶安全的智能评估。为了重构汽车驾驶员的生理状态，作者建议使用一种专为生理参数设计的生物传感系统，结合了近红外光谱的 LED 组和光电探测器，以检测生理信号 PPG，并连接到心脏活动，从而根据受试者的注意水平监测驾驶员的昏睡状态。该论文还提出了基于智能驾驶情景理解的进一步驾驶安全评估。
