Avoiding Collision with Oncoming Vehicles when Overtaking

Abstract

Many road accident fatalities stem from issues associated with the overtaking maneuver (OM). This study uses an autonomous emergency steering system, to examine OMs in an oncoming vehicle (OV) situation. The generation of the OM was achieved with the use of the trapezoidal acceleration profile (TAP), while taking into account the limits of the tire-road friction coefficient (µ) and maximum lateral jerk (jmax). The risk of collision with the OV was measured using a distance margin (dm), which is defined as the distance between the ego vehicle (EV) and OV, at the close of the OM. The results derived from investigations on the effect of the velocity of the OV on the dm, deliver crucial information regarding collision avoidance, during the execution of an OM in an OV situation.
