Abstract

The disclosed processing device for assisting the driving of a vehicle is characterized by being provided with a first data acquisition unit that acquires back-left image data, a second data acquisition unit that acquires back-right image data, and a lane divergence detection unit having a lane divergence detection state and a lane divergence detection / suppression state; and is further characterized by the aforementioned lane divergence detection unit, in the aforementioned lane divergence detection state, estimating a first distance between a left boundary and the aforementioned vehicle on the basis of the aforementioned back-left image data, estimating a second distance between a right boundary and the aforementioned vehicle on the basis of the aforementioned back-right image data, and, when either or both is the case of the aforementioned first distance being at or below a first baseline value derived using a predetermined method or the aforementioned second distance being at or below a second baseline value derived using a predetermined method, executing a first signal generation operation that generates a first signal for at least one of: providing a warning; controlling at least one of a steering device and a braking device; and transmitting a signal outside the aforementioned vehicle.

Description

[0001] Cross References to Related Applications [0002] This application is based upon and claims the benefit of priority from prior Japanese Patent Application No. 2010-68522 filed on March 24, 2010, the entire contents of which are hereby incorporated by reference. technical field [0003] The embodiments described here relate to a processing device for driving assistance for a vehicle, a driving assistance device for a vehicle, and a vehicle device. Background technique [0004] There is a lane departure warning system (LDWS: Lane Departure Warning System) which warns the driver that the vehicle departs from the running lane (lane). [0005] For example, in Japanese Unexamined Patent Publication No. 2008-250904, a configuration has been proposed in which, when the recognition accuracy of white lines is insufficient in an on-vehicle camera that takes pictures of the front, an image captured by an on-vehicle camera that takes pictures from the side is used. Therefore, the...
