Problems solved by technology

[0008] In addition, the detachable mode only guarantees that the headlights reflected in the image can be recognized as two lights in the test environment stipulated by the law, and does not guarantee that the headlights can be recognized in the actual use environment.
Therefore, although the operation is performed in the detachable mode, the headlight reflected in the image may not be recognized as two lamps.
In this case, the driver may misjudge the difference between the automatic two-wheeled vehicle and the automatic four-wheeled vehicle

[0030] [1-1. Structure]

[0031] Such as figure 1 As shown, the driving assistance system 2 includes an image processing device 1 . The image processing device 1 is an ECU mounted on a vehicle. ECU is an abbreviation for Electronic Control Unit. The image processing device 1 includes a known microcomputer including a CPU 101 and a semiconductor memory 103 such as RAM, ROM, and flash memory. Various functions of the image processing device 1 are realized by the CPU executing programs stored in a non-migrating, tangible recording medium. In this example, the semiconductor memory corresponds to a non-transferable physical recording medium in which the program is stored. In addition, by executing the program, the method corresponding to the program is executed. In addition, the image processing device 1 may include one microcomputer, or may include a plurality of microcomputers. In addition, the image processing apparatus 1 may be realized by a digital circuit including a pl...

[0063] [2-1. Differences from the First Embodiment]

[0064] The basic configuration of the second embodiment is the same as that of the first embodiment, so the differences will be described below.

[0065] In the aforementioned first embodiment, the exposure time T when the camera captures the image is used as an important factor affecting brightness to determine whether the image is in a recognizable state or in an unrecognizable state. On the other hand, the second embodiment differs from the first embodiment in that the illuminance L around the vehicle is used as an important factor affecting brightness to determine whether an image is recognizable or unrecognizable.

[0066] [2-2. Processing]

[0067] Next, use Figure 6 The flowchart of the second embodiment is replaced by the CPU 101 of the image processing device 1 of the second embodiment figure 2 The driving assistance processing_2 executed by the driving assistance processing_1 of the first embodiment shown wil...

[0085] [3-1. Differences from the First Embodiment]

[0086] The basic configuration of the third embodiment is the same as that of the first embodiment, so differences will be described below.

[0087] In the aforementioned first embodiment, the exposure time T when the camera captures the image is used as an important factor affecting brightness to determine whether the image is in a recognizable state or an unrecognizable state. On the other hand, the third embodiment is different from the first embodiment in that the luminance distribution in the image is used as an important factor affecting brightness to determine whether the image is recognizable or unrecognizable.

[0088] [3-2. Processing]

[0089] Next, use Figure 7 The flow chart of the above is replaced by the CPU 101 of the image processing device 1 of the third embodiment figure 2 The driving assistance processing_3 executed by the driving assistance processing_1 of the first embodiment shown will be describ...

Abstract

The invention relates to a driving assistance system and a driving assistance method. The acquiring unit (S105) acquires images of the surroundings of the host vehicle. The display unit (S155) displays the image acquired by the acquisition unit. The detection unit ( S110 ) detects an important factor affecting the brightness of the entire image, that is, an important factor affecting brightness. The judging unit (S125, S140) judges that each of the plurality of luminaires reflected in the image cannot be recognized on the display unit when the important factor affecting brightness detected by the detecting unit does not satisfy the preset recognition judgment condition. The state is the unrecognized state. The reporting unit (S135, S150) reports the content when it is judged by the judging unit that it is in an unrecognizable state.
