Abstract
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 miss alarm caused by sensor errors leads to decrease of driver’s 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 proposed warning methods to increase driver's trust in the system even with low sensor reliability by utilizing the sensor reliability information. We investigate the effectiveness of the warning methods in high and low workload situations by driving simulator experiments.
