Abstract
Official abstract text for this publication.
A vehicle control device includes: a signal processing integrated circuit (IC) unit for performing image processing on an output from a camera mounted in a vehicle and outputting image data obtained through the image processing; a recognition processing IC unit provided as another unit different from the signal processing IC unit, for performing recognition processing for recognizing an external environment of the vehicle based on the image data received from the signal processing IC unit and outputting external environment data obtained through the recognition processing; and a judgment IC unit provided as another unit different from the signal processing IC unit and the recognition processing IC unit, for performing judgment processing for cruise control of the vehicle based on the external environment data received from the recognition processing IC unit and outputting a cruise control signal based on the judgment processing result.
First claim
Opening claim text (preview).
What is claimed is: 1 . A vehicle control device comprising: a signal processing integrated circuit (IC) unit for receiving an output from a camera mounted in a vehicle, performing image processing on the output from the camera, and outputting image data obtained through the image processing; a recognition processing IC unit provided as another unit different from the signal processing IC unit, for receiving the image data, performing recognition processing for recognizing an external environment of the vehicle based on the image data, and outputting external environment data obtained through the recognition processing; and a judgment IC unit provided as another unit different from the signal processing IC unit and the recognition processing IC unit, for receiving the external environment data, performing judgment processing for cruise control of the vehicle based on the external environment data, and outputting a cruise control signal based on a result of the judgment processing. 2 . The vehicle control device of claim 1 , wherein the recognition processing IC unit performs the recognition processing of the external environment of the vehicle using deep learning techniques. 3 . The vehicle control device of claim 1 , further comprising a backup safety IC unit for receiving the image data output from the signal processing IC unit, performing recognition processing of the external environment of the vehicle from the image data based on a predetermined rule without using deep learning techniques, and performing judgment processing for cruise control of the vehicle based on external environment data obtained through the recognition processing, wherein the judgment processing IC unit receives a result of the judgment processing by the backup safety IC unit, and outputs a backup cruise control signal based on the result of the judgment processing by the backup safety IC unit instead of the cruise control signal if an abnormality is detected in at least one of the vehicle or a passenger.
