Driver's workload tends to be increased during driving under complicated traffic environments like lane-changing operation. In such cases, rear collision warning is effective for reduction of cognitive workload. On the other hand, it is pointed out that false alarm or missing alarm caused by sensor errors leads to decrease of driver trust in the warning system and it can result in low efficiency of the system. Suppose that sensor reliability information is provided in real-time. In this paper, we propose a novel warning method to increase driver trust in the system even with low sensor reliability by utilizing sensor reliability information. We investigate the effectiveness of the warning methods in high and low workload situations by driving simulator experiments.
► A new Rear Obstacle Warning System (ROWS) is proposed to increase the driver's trust. ► The new ROWS is expected to increase trust when sensor reliability is low condition. ► The effectiveness of warning system was evaluated considering the workload. ► The proposed method is effective in the middle range workload situation.
