Embodiment Construction

[0039] figure 1 Among them, U is a controller (control unit) composed of a microcomputer, which constitutes a control device. To this controller U, signals from various sensors or machines 1 to 7 are input. That is, 1 is a vehicle speed sensor for detecting the vehicle speed. 2 is a yaw rate sensor for detecting a yaw rate (yaw rate) acting on the own vehicle. 3 is a steering angle sensor that detects the steering angle (including the steering direction). 4 is a camera that shoots the front of the vehicle, and detects road signs ahead (especially road signs prohibiting travel outside the designated direction). 5 is a turn signal (direction indicator), which detects the driver's intention to turn right or left. Reference numeral 6 denotes map data (navigation device), which is used to know the presence of road signs, the state of the road ahead of the own vehicle, and the like. 7 is a camera inside the vehicle, which detects the direction of sight of the driver of the own ...

Abstract

It is an object of the present invention to provide a sign recognition system which is prevented from being troubled by a problem that the driver does not give in attention to the caution display and travels to the prohibition direction. The sign recognition system includes a display unit (11) for displaying caution information regarding a traffic sign, a specific road identification detecting unit (an outdoor camera (4)) for detecting a specific road sign that is prohibited from traveling in a predetermined direction ahead, a traveling direction detecting unit (a turning lamp (5)) for detecting a traveling direction of the vehicle, and a control unit (U). The control unit (U) causes the display unit (11) to not display the caution when the traveling direction of the vehicle coincides with the designated direction of the specific road sign and makes the display unit (11) to display the caution when the vehicle travels in a direction different from the designated direction of the specific road sign. When the caution is displayed, it is preferable to carry out an alarm (especially a voice alarm) when the driver's line of sight is not oriented towards a specific road sign.

Description

technical field [0001] The present invention relates to a sign recognition system. Background technique [0002] It is very disadvantageous in preventing danger and the like to overlook the signals and road signs attached to the road. Patent Document 1 discloses providing a detection unit that detects the driver's gaze direction, and when the driver does not visually recognize a signal, a road sign, etc. ahead of the host vehicle, an attention display is performed. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2014-120111. Contents of the invention [0004] Problems to be solved by the invention: [0005] As described in Patent Document 1, it is advantageous to display caution when a road sign or the like is overlooked in order to prevent danger, etc. [0006] On the other hand, among the road signs, there is a road sign "prohibited to travel outside the designated direction". For example, at the front position of the crossroad ahead, a road sign indicating...
