Driver's workload tends to be increased during driving under complicated traffic environment like lane change. 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 causes decrease of driver's trust in the warning system and it can result in low efficiency of the system. In this paper, supposing that information of the recognition reliability of the sensor is provided in real-time, we propose the new warning method that displays information calling for attention when the recognition reliability is low to reduce false alarm and missing alarm and maintain the trust in the system. The effectiveness of this warning method was confirmed with a driving simulator.
