Claims (4)

A visual assistance device for assisting visual recognition by a driver of a vehicle provided with a driver monitoring sensor, an outside monitoring sensor, and a warning output device,
Based on driver monitoring information of the driver monitoring sensor, a driver state information acquisition unit that acquires state information about the driver;
A target detection unit for detecting a target existing around the vehicle based on the vehicle monitoring information of the vehicle monitoring sensor;
It is determined whether the target belongs to a plurality of groups classified in advance, and it is determined whether or not the driver's visual observation is appropriate based on the state information and the group information of the group to which the target belongs. A visual judgment unit to perform,
A warning information output unit that outputs warning information for generating a warning in the warning output device when the visual determination unit determines that the driver's visual inspection is inappropriate ;
The state information includes line-of-sight direction information indicating the direction of the driver's line of sight and line-of-sight dwell time information indicating the dwell time of the driver's line of sight, and the group information is individually set for each group in advance. Threshold value information representing a threshold value of the accumulated dwell time of the driver's line of sight, the visual determination unit based on the position information representing the position of the target, the line-of-sight direction information, and the line-of-sight dwell time information, The line-of-sight accumulated dwell time information representing the accumulated dwell time of the driver's line of sight directed toward the subject is calculated, the calculated line-of-sight accumulated dwell time information is compared with the threshold information, and the line-of-sight accumulated dwell time information is the threshold value The visual assistance device that determines that the visual observation of the driver is appropriate when the information is more than information . The plurality of groups include at least a first group including a target whose motion is unpredictable, a second group including a target whose motion can be predicted, and a third group including a target substantially free of motion. The threshold information of the first group is greater than the threshold information of the second group, and the threshold information of the second group is greater than the threshold information of the third group. Item 20. The visual assistance device according to Item 1 . A visual assistance method for assisting visual recognition by a driver of a vehicle including a driver monitoring sensor, an outside monitoring sensor, and a warning output device,
Based on driver monitoring information of the driver monitoring sensor, a driver state acquisition step of acquiring state information about the driver;
An object detection step for detecting an object present in the vicinity of the vehicle based on the vehicle monitoring information of the vehicle monitoring sensor;
The target detected by the target detection step is identified as belonging to a plurality of groups classified in advance, and based on the state information and the group information of the group to which the target belongs, the driver's visual inspection is performed. A visual determination step for determining whether or not was appropriate;
A warning information output step for outputting warning information for generating a warning in the warning output device when it is determined by the visual determination step that the driver's visual inspection is inappropriate ;
The state information includes line-of-sight direction information indicating the direction of the driver's line of sight and line-of-sight dwell time information indicating the dwell time of the driver's line of sight, and the group information is individually set for each group in advance. Threshold value information representing a threshold of the accumulated dwell time of the driver's line of sight, and the visual determination step is based on the position information representing the position of the target, the line-of-sight direction information, and the line-of-sight dwell time information. The line-of-sight accumulated dwell time information representing the accumulated dwell time of the driver's line of sight directed toward the subject is calculated, the calculated line-of-sight accumulated dwell time information is compared with the threshold information, and the line-of-sight accumulated dwell time information is the threshold value A visual assistance method for determining that the visual observation of the driver is appropriate when the information is more than information . The program which makes a computer perform the process of each step of the visual assistance method of Claim 3 or the function of each part with which the visual recognition assistance apparatus of Claim 1 or Claim 2 is provided.
