This study aims to develop an advanced driver assistance system (ADAS) to avoid collision with an oncoming darting-out vehicle from a blind area when turning right at intersections. As commercialized technology, ADAS activates Autonomous Emergency Braking to avoid collisions when on-board sensors detect oncoming vehicles during right turns. However, the system may not avoid a collision with a target that suddenly darts out from a blind area. Connected vehicles in coordination with infrastructure have been commercialized as ADAS technologies for this purpose, but they cannot provide assistance unless installing communication equipment for both the vehicle and infrastructure. Therefore, this paper proposed an ADAS that uses on-board sensors without depending on infrastructure facilities to control the vehicle speed to avoid collisions. This system calculates the dangerous speed criterion of the ego vehicle that has a high risk of collision when a darting out occurs and provides speed assistance to escape from the dangerous speed region. Simulation results showed that the proposed system effectively reduces the possibility of collisions.
