Vehicular acceleration suppression device

摘要

A vehicular acceleration suppression device reduces the degradation in the drive performance due to the acceleration suppression control activated outside the parking region. A parking frame line candidate which is a candidate of a parking frame line is extracted from a bird's-eye view image acquired by performing a bird's-eye view conversion on a captured image around a vehicle, and a parking frame line candidate corresponding line corresponding the parking frame line candidate is extracted from the captured image of the front of the vehicle. Then, the parking frame line candidate corresponding to the parking frame line candidate corresponding line length of which is longer than a parking frame line length threshold is eliminated from the candidate to be detected as the parking frame.

1. A vehicular acceleration suppression device, comprising:
a camera configured to capture an image of a region including a road surface around a vehicle; and a controller configured to:
detect an acceleration manipulation amount of an acceleration manipulation element manipulated by a driver to instruct acceleration,control the acceleration to be generated at the vehicle depending on the detected acceleration manipulation amount,cut off a partial image from an image captured from the camera,create a bird's-eye view image based on the partial image,extract a line located on the road surface from the bird's-eye view image as a parking frame line candidate,detect a parking frame from the parking frame line candidate,perform an acceleration suppression control which reduces the controlled acceleration based on the detected parking frame,extract a parking frame line candidate corresponding line corresponding to the extracted parking frame line candidate from the captured image of the front of the vehicle captured by the camera, andeliminate the parking frame line candidate corresponding to the parking frame line candidate corresponding line from candidates to be detected as the parking frame, when it is determined that a length of the parking frame line candidate corresponding line is longer than a predefined parking frame line length threshold,wherein a segment of the parking frame line candidate corresponding line does not appear in the bird's-eye view image is extracted from a portion of the captured image of the front of the vehicle, the portion being other than the partial image converted into the bird's-eye view image.
