Abstract

In order to solve traffic safety problems caused by inner wheel difference and visual blindness during semi-trailer turning, a trajectory equation under dynamic rectangular coordinate system was constructed based on vehicle turning theory. Then, a hazard identification model for obstacles in blind zones was developed considering existing radar detection technology. Building on this, a real-time monitoring, warning and safety guarantee system was proposed, composed by hardware facilities including vehicle-side phase-controlled radar, adjustable rearview mirror, audible and visual alarm, nighttime fill light, and software program with single-chip microcomputer as a key. The results show that the system can provide accurate real-time turning status and safety early warning information for semi-trailer drivers and off-vehicle traffic participants, avoiding risks in blind zones and therefore fulfilling its function of early warning and safety guarantee. © 2020 China Safety Science Journal.
