no. 1 Embodiment approach

[0028] First, the first embodiment will be described. Such as figure 1 As shown, the information presentation device 200 according to the first embodiment is mounted on a vehicle V such as a passenger car capable of switching between manual driving and automatic driving. Manual driving means that the driver of the vehicle V mainly drives the vehicle V. As shown in FIG. The automatic driving is a vehicle control for driving the vehicle V automatically toward a preset destination. In automatic driving, the vehicle V travels automatically without a driver's driving operation. Here, the automatic driving control of the vehicle V is performed by the automatic driving system 100 mounted on the vehicle V. As shown in FIG.

[0029] (Details of the automated driving system)

[0030] The automatic driving system 100 includes a GPS [Global Positioning System] receiver 1 , an external sensor 2 , an internal sensor 3 , a map database 4 , an actuator 5 , and an automatic driving ECU [El...

no. 2 Embodiment approach

[0106] Next, a second embodiment of the information presentation device will be described. Hereinafter, the description will focus on the differences from the information presentation device 200 of the first embodiment, and the same reference numerals will be assigned to the same elements as those of the information presentation device 200 of the first embodiment, and details will be omitted. instruction of. Such as Figure 6 As shown, the information presentation device 200A according to the second embodiment discriminates the type of non-driving behavior, calculates the degree of participation for each type of non-driving behavior, and presents information.

[0107] Specifically, 200 A of information presentation apparatuses are equipped with the state detection sensor 21, the information presentation device 22, and information presentation ECU23A. Like the information presentation ECU 23 in the first embodiment, the information presentation ECU 23A is an electronic contro...

no. 3 Embodiment approach

[0125] Next, a third embodiment of the information presentation device will be described. Hereinafter, the difference from the information presentation device 200A of the second embodiment will be mainly described, and the same reference numerals will be assigned to the same elements as those of the information presentation device 200A of the second embodiment, and detailed description will be omitted. . Such as Figure 9 As shown, the information presentation device 200B according to the third embodiment presents information based on the degree to which the driver's posture deviates from the driving posture.

[0126] Specifically, the information presentation device 200B includes a state detection sensor 21, an information presentation device 22, and an information presentation ECU 23B. The information presentation ECU 23B has a behavior determination unit 24B, a participation degree calculation unit 25A, an alternation frequency calculation unit 26A, a system confidence de...

Abstract

The present invention relates to an information presentation device for appropriately presenting information to a driver of a vehicle. The information prompting device (200) has: a behavior discrimination unit (24), which discriminates the driver's driving behavior and non-driving behavior; the participation degree calculation unit (25), based on the discrimination result of the driving behavior in the participation degree calculation period (d) and At least any one of the discrimination results of behaviors other than driving to calculate the driver's participation in driving; the system confidence degree acquisition part (27) obtains the system confidence degree of automatic driving control; and the information prompt part (28), Drivers are prompted with information based on engagement and system confidence.

Description

technical field [0001] The present invention relates to an information presenting device for presenting information to a driver of a vehicle. Background technique [0002] For example, Patent Document 1 describes an information presentation device for presenting information to a driver of a vehicle capable of switching between automatic driving and manual driving based on the driver's awareness of driving. [0003] Patent Document 1: International Publication No. 2015 / 151243 [0004] In the device described in Patent Document 1, for example, when the driver alternately performs driving behavior and non-driving behavior in a short period of time, it is determined that the driver's level of consciousness is low even though the total time of driving behavior is more than a certain time. Low. As a result, information may not be properly presented to the driver. Therefore, in this technical field, it is desired to appropriately present information to the driver of the vehicle....
