Risk predictive shared deceleration control: Its functionality and effectiveness of an early intervention support

Autonomous Emergency Braking systems have been already introduced to the markets to realize road traffic zero fatalities, and humans positively evaluated the functions of such assistance system. However, such assistance system reaches its limit when there are unexpected moving obstacles appearing suddenly from poor visibility area, such as a corner of intersection, and a space behind a parked vehicle. This paper focuses on a parked vehicle overtaking scenario that an occluded pedestrian suddenly might intend to cross a road, and a risk predictive shared deceleration control system which can prepare and avoid for a hidden collision risk is proposed. Under a driving simulator experiment, we investigated its functionality and effectiveness of the proposed early intervention support, and we confirmed that the proposed assistance system can be effective for guiding the drivers to trace the desired velocity.
