Abstract

To not issue an inattentive driving warning when there is no need to issue a warning about inattentive driving.SOLUTION: A detection device (9) capable of detecting a visual direction of a driver (40) of a vehicle (1) is provided. For each point that the vehicle (1) travels, visual inspection information including a visual inspection necessary area (AA) of the driver (40) when the driver (40) of the vehicle (1) is conducting a required visual inspection confirmation due to inattentive driving, and a visual inspection necessary time is stored in a data storage unit. The visual inspection information stored in the data storage unit is acquired from the data storage unit, and a warning generation unit (22) will stop issuing an inattentive driving warning when the visual direction of the driver (40) of the vehicle (1) is directed toward the visual inspection necessary area (AA) in the present position of the vehicle (1) within a period not exceeding a visual inspection necessary time in the present position of the vehicle (1).SELECTED DRAWING: Figure 7

Claims

1. It comprises a detection device capable of detecting the direction in which the vehicle driver is looking, a warning generation unit that issues a distraction warning to the vehicle driver, and a processor. For each point the vehicle travels, visual information including the area and duration of visual checks performed by the driver due to distracted viewing is stored in the data storage unit. The processor acquires visual information stored in the data storage unit from the data storage unit. A distraction warning system that, when the driver's line of sight is directed towards the area requiring visual observation at the vehicle's current location, within a range that does not exceed the required viewing time at the vehicle's current location, the warning generating unit ceases issuing a distraction warning.

2. The distraction warning system according to claim 1, wherein the processor generates a distraction warning in the warning generation unit when the direction in which the vehicle driver is looking exceeds the required viewing time at the vehicle's current position and is directed towards the area where the driver is required to look at the vehicle's current position.

3. The distraction warning system according to claim 1, wherein the data storage unit comprises a server, visual information transmitted to the server from multiple different vehicles is stored in the server, and the visual inspection area and the visual inspection time are determined based on the visual information stored in the server.

4. The distraction warning system according to claim 1, wherein the detection device is capable of detecting the direction of the vehicle driver's face in addition to the direction of the vehicle driver's gaze, and visual information including the area and time required for the driver to be visually inspected when the necessary visual check is performed, and visual information including the area and time required for the driver to be facing when the necessary visual check is performed are stored in the data storage unit, and when the detection device is capable of detecting the direction of the vehicle driver's gaze, the warning generating unit refrains from issuing a distraction warning when the driver's gaze is directed towards the area required for the driver to be visually inspected at the vehicle's current position, within a range that does not exceed the time required for visual inspection at the vehicle's current position, and when the detection device is capable of detecting the direction of the vehicle driver's gaze, the warning generating unit refrains from issuing a distraction warning when the driver's face is directed towards the area required for the driver to be facing at the vehicle's current position, within a range that does not exceed the time required for the driver to be facing at the vehicle's current position.

5. The distraction warning system according to claim 4, wherein the data storage unit consists of a server, visual information transmitted to the server from multiple different vehicles is stored in the server, and the visual inspection required area and visual inspection required time and the face-direction required area and face-direction required time are determined based on the visual information stored in the server.
