Konferens: FAST-zero'15: 3rd International symposium on future active safety technology toward zero traffic accidents, 2015, Gothenburg

This study examines the driver assistance system to predict driving behavior considering information on the pre-preceding vehicle. The system indicates the predicted driving evaluation index at the rear-end of the preceding vehicle to avoid the driver’s distraction. Driving simulator experiments are carried out with several participants who are instructed to follow a preceding and a visible pre-preceding vehicles with and without the driving assistance system. The participants with the assistance system could reduce the relative speed with the pre-preceding vehicle and acceleration of the following vehicle. These effects make it possible to suppress the variation of the collision risk to the preceding vehicle and to reduce fuel consumption of the following vehicle. In addition, the proposed assistance system shortened the drivers’ reactions to the emergency deceleration of the preceding vehicle in comparison with the conventional assistance system, which is indicated at the onboard monitor in the following vehicle.
