Abstract:
1. A vehicle drive support device comprising: a red arrow light information acquisition unit that acquires information regarding a red arrow light which displays a signal for prohibiting travel in a particular turning direction; a drive assistant operation unit configured to supply information to a motorist of a host vehicle based on the information acquired by the red arrow light information acquisition unit and to drive the host vehicle without depending on manipulation by the motorist based on the information acquired by the red arrow light information acquisition unit, the drive assistant operation unit supplies the information to the motorist or drives the host vehicle dependent on a monitored state of the vehicle; a travel direction detection unit that detects a travel direction of the host vehicle; a vehicle traffic signal information acquisition unit that acquires information regarding an illumination state of a vehicle traffic signal which displays a signal for prohibiting travel in a straight direction; and an accelerator pedal sensor that detects whether or not an accelerator pedal of the host vehicle is pressed, wherein, in a case where a travel direction of the host vehicle detected by the travel direction detection unit corresponds with a direction in which a signal of the red arrow light relating to the information acquired by the red arrow light information acquisition unit prohibits travel, the drive assistant operation unit supplies information or drives the host vehicle, wherein, in a case where the vehicle traffic signal relating to the information acquired by the vehicle traffic signal information acquisition unit displays a signal for prohibiting travel in a straight direction, and the red arrow light relating to the information acquired by the red arrow light information acquisition unit displays a signal for prohibiting travel in the particular turning direction, and in a case where a travel direction of the host vehicle detected by the travel direction detection unit is a straight direction, the drive assistant operation supplies information or drives the host vehicle when the accelerator pedal sensor detects a pressing amount of the accelerator pedal, and wherein, in a case where the travel direction of the host vehicle detected by the travel direction detection unit corresponds with a direction in which a signal of the red arrow light relating to the information acquired by the red arrow light information acquisition unit prohibits the travel, the drive assistant operation unit supplies information or drives the host vehicle without depending on whether or not the accelerator pedal sensor detects a pressing amount of the accelerator pedal.
