Problems solved by technology

If you want to adjust the amount of manual driving operations to match the amount of automatic driving operations, you may be distracted from making the amount of manual driving operations consistent with the amount of automatic driving operations
In addition, for example, if a switch from manual driving to automatic driving is performed in a state where the conditions are not met, the manual driving operation amount suddenly changes to the automatic driving operation amount according to the driving rules disclosed in Patent Document 2, and there is a switch. Possibility of lack of smoothness in forward and backward moves

[0069] Hereinafter, embodiments will be described based on the drawings. figure 1 It is a block diagram showing the vehicle driving system 100 of 1st Embodiment. The vehicle driving system 100 includes an actuator 110 , an automatic driving device 120 , a manual driving evaluation unit 130 , and a driving switching unit 140 . The vehicle driving system 100 is mounted on the host vehicle 1 . The host vehicle 1 is a vehicle on which the vehicle driving system 100 is mounted when the vehicle driving system 100 is used as a reference. The vehicle includes a drive source such as an engine and wheels. Cars, buses, trucks, etc. are included in the vehicle.

[0070] The actuator 110 includes an actuator for driving the host vehicle 1 , an actuator for stopping the host vehicle 1 , and an actuator for changing the traveling direction of the host vehicle 1 .

[0115] Next, the second embodiment will be described. In this second embodiment and the following description, unless otherwise mentioned, elements with the same reference numerals as those used so far are the same as those in the previous embodiments. The elements of the figure markers are the same. In addition, when only a part of a structure is demonstrated, the previously demonstrated embodiment can be applied to another part of a structure.

[0116] exist Figure 4 A configuration diagram of a vehicle driving system 200 according to the second embodiment is shown. The vehicle driving system 200 of the second embodiment differs from the vehicle driving system 100 of the first embodiment in that it does not include the manual driving evaluation unit 130 . In addition, since the manual driving evaluation unit 130 is not provided, the processing of the switching determination unit 241 is different from that of the switching determination unit 141 of the first embodiment. ...

[0120] exist Image 6 A configuration diagram of a vehicle driving system 300 according to the third embodiment is shown. The vehicle driving system 300 of the third embodiment adds a manual driving preparation determination unit 350 to the vehicle driving system 200 of the second embodiment. In addition, the processing performed by the switching determination unit 341 is different from that of the switching determination unit 241 of the second embodiment.

[0121] The manual driving preparation determination unit 350 determines whether or not the driver is ready to start the driving operation. Specifically, the driver's preparation for starting the driving operation can be the driver's sitting posture facing the front and the driver holding the steering wheel. When judging whether or not these two preparations have been completed, the manual driving preparation judging unit 350 obtains an image from a camera that captures the driver's seat, and analyzes the image to judge t...

Abstract

The present invention is provided with: a driving rule determination acquisition unit (S12, S13) that acquires driving rule determination information for automatic driving; the driving rule determination information indicates a result of comparison determination between a driving rule and an automatic driving characteristic, which is a characteristic of the host vehicle when the host vehicle travels on the travel track generated by the automatic driving device by automatic driving. A driving switching unit that switches a driving mode between an automatic driving mode in which automatic driving is performed and a manual driving mode in which manual driving is performed; and a switching determination unit that permits the driving switching by the driving switching unit on the basis of a condition in which the driving rule determination information of the automatic driving acquired by the driving rule determination acquisition unit indicates that the automatic driving characteristics meet the driving rule.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims the priority of Patent Application No. 2019-186267 filed in Japan on October 9, 2019, the entire contents of which are incorporated herein by reference. technical field [0003] The invention relates to a vehicle driving switching device, a vehicle driving system, and a vehicle driving switching method for switching between automatic driving and manual driving. Background technique [0004] Techniques for determining whether to allow switching between manual driving and automatic driving are known. The automatic driving apparatus disclosed in Patent Document 1 allows switching to automatic driving when the difference between the manual driving operation amount of the driver during manual driving and the automatic driving operation amount calculated by the automatic driving calculation unit is equal to or less than a threshold value. [0005] Patent Document 2 discloses an apparatus for estimatin...
