Problems solved by technology

[0004] For example, it may be difficult to recognize the signal light from the host vehicle, such as when the signal light is covered by trees that exist near the signal light.
In such a case, even if the signal lamp identification device performs the identification process of the signal lamp, the identification of the signal lamp cannot be realized.

Embodiment Construction

[0020] Embodiments of the present disclosure will be described below with reference to the drawings. In addition, in the description of the drawings, the same reference numerals are attached to the same elements, and overlapping descriptions are omitted.

[0021] figure 1 The automatic driving system 100 shown is mounted on an own vehicle V such as a passenger car, and executes automatic driving control of the own vehicle V. The automatic driving system 100 starts the automatic driving control of the host vehicle V when the passenger performs an automatic driving control start operation (operation of pressing an automatic driving start button, etc.).

[0022] The automatic driving control is vehicle control for automatically driving the own vehicle V toward a preset destination. In the automatic driving control, the host vehicle V runs automatically without the driver performing a driving operation.

[0023] Such as figure 1 As shown, the automatic driving system 100 inclu...

Abstract

The invention provides a signal light identification device and an automatic driving system. The signal light recognition device includes: a signal light recognition unit that performs signal light recognition processing based on a result of a camera image; an external situation recognition unit that recognizes the size and position of surrounding vehicles; and an occlusion environment determination unit that determines an area in front of the vehicle. Whether it is a signal light blocking environment where the view from the camera to the signal light is blocked by surrounding vehicles. The signal light recognition unit does not perform the signal light recognition process in the difficult area, and does not perform the signal light recognition process when it is determined that the area ahead of the host vehicle is a signal light blocking environment.

Description

technical field [0001] The present disclosure relates to a signal light recognition device and an automatic driving system equipped with the signal light recognition device. Background technique [0002] For example, as described in Patent Document 1 below, there is a traffic light recognition device that recognizes a traffic light in front of the host vehicle. The signal light recognition device recognizes the signal light based on the position of the own vehicle, the installation position of the signal light included in the map information, and the imaging result of the imaging unit. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2016-042226 [0004] For example, it may be difficult for the own vehicle to recognize the signal light, such as when the signal light is covered by trees existing near the signal light. In such a case, even if the signal lamp recognition device executes the recognition process of the signal lamp, the recognition of the signal lamp ca...
