Title: Automatic stop assistance device
Inventor: IMAMURA TOMONE
IPC: G08G1/16
Filed: 2019-09-24
Abstract: To provide a retrofittable device which optimizes an object for automatic stop to human and mainly involves intervention of an accelerator pedal in order to suppress a person from being hit (a physical injury) due to runway of a traveling body such as an automobile caused by overstepping of an accelerator pedal, which has been a social problem in recent years.SOLUTION: An image in a traveling direction of a traveling body is acquired by a camera 11. Person detection and joint position information extraction processing for the person are performed on the acquired image by a device 12. Processing for obtaining a distance between the traveling body and the person is performed from information on presence/absence of a joint of the person in the image or pixel information among joints with a device 13 by using the obtained joint position information. External devices 15, 16, and 17 are controlled by a device 14 in accordance with the obtained distance information. The external device 15 prevents overstepping of an accelerator pedal by depressing back the accelerator pedal and guides a driver of the traveling body so as to switch from the accelerator pedal to a brake pedal by alerting the driver from a reaction feeling of the pedal. These component devices have structures which can be easily retrofitted.SELECTED DRAWING: Figure 1
