VEHICLE APPROACH DETECTION DEVICE AND VEHICLE APPROACH DETECTION METHOD
First Claim
1. A vehicle approach detection device, which is mounted on a vehicle, comprising:
- a vehicle external information detector configured to detect at least one of a vehicle surrounding video for showing an observed area used to observe irradiation light from another vehicle or a vehicle surrounding environmental sound as vehicle external information, to thereby output the detected vehicle external information; and
an electronic control unit comprising a vehicle approach detection unit configured to determine whether or not the another vehicle is approaching the vehicle based on the vehicle external information input from the vehicle external information detector.

Abstract
Provided are a vehicle approach detection device and a vehicle approach detection method that are capable of detecting an approach of another vehicle without installing a dedicated device on a road. At least one of a vehicle surrounding video for showing an observed area (for example, road surface) used to observe irradiation light (for example, headlight beam emitted from a headlight of another vehicle) from another vehicle and a vehicle surrounding environmental sound is detected as vehicle external information, and it is determined based on the detected vehicle external information whether or not another vehicle is approaching an own vehicle.

11. A vehicle approach detection method to be executed by an electronic control unit mounted on a vehicle, comprising:
-
acquiring vehicle external information from a vehicle external information detector configured to detect at least one of a vehicle surrounding video for showing an observed area used to observe irradiation light from another vehicle or a vehicle surrounding environmental sound as vehicle external information, to thereby output the detected vehicle external information; and determining whether or not the another vehicle is approaching the vehicle based on the acquired vehicle external information.
