Problems solved by technology

On the other hand, there is a possibility that the driver in automatic driving will be in a driver's state where it is difficult to ensure safe driving, but that is not assumed in conventional manual driving.
This point has not been considered at all in the conventionally proposed technology, so it is difficult to ensure safe driving in the case of such a dangerous driver state unique to automatic driving.

Embodiment Construction

[0020] Examples are described below.

[0021] A. Device structure:

[0022] Figure 1A A vehicle 1 equipped with the driving assistance device 10 of this embodiment is shown in . Such as Figure 1A As shown, the vehicle 1 is equipped with a control device 100 forming a main part of the driving assistance device 10 of this embodiment, an automatic driving device 400 for automatically driving the vehicle 1 , a car navigation system, and the like.

[0023] In manual driving, the driver drives the vehicle 1 by steering the steering wheel 500 or by operating an accelerator pedal, a brake pedal, etc. not shown in the figure. In addition, when the driving state is switched to the automatic driving state, the automatic driving device 400 operates the steering wheel 500 , the accelerator pedal, the brake pedal, and the like instead of the driver. An actuator 502 is attached to the shaft of the steering wheel 500 , and a steering angle sensor is incorporated in the actuator 502 . The...

Abstract

A driving support device (10) is provided. The driving support device comprises: a driver state detecting unit (120) which detects, as a driver state, that the driver is in a careless state; an alerting unit (140) which, if it has been detected that the driver is in a careless state, issues an alert to the driver; a driving operation unit (500) operated by the driver in order to perform driving operations; and a driving state switching unit (130) which, if it detects that the driving operation unit has been operated by the driver while the vehicle is in an automatic drive state, switches at least one driving operation in said automatic drive state to a manual drive state. If at least one driving operation in the automatic drive state has been switched to the manual drive state by the driving state switching unit, the driver state detecting unit detects, as the driver state, that said driver is in an excited state, and if the driver is detected to be in an excited state, the alerting unit issues an alert to said driver.

Description

[0001] This application claims priority based on Japanese Patent Application No. 2014-24949 for which it applied on February 12, 2014, and uses it here by reference. technical field [0002] The present disclosure relates to a technology that is mounted on a vehicle capable of switching a driving state between an automatic driving state and a manual driving state, and that detects the state of a driver to assist driving. Background technique [0003] A technology has been developed to ensure safe driving by detecting the state of the driver based on the direction of the driver's gaze and biological information (eyelid behavior, heart rate, etc.) and reminding the driver if he is in a state of inattention And this technology has been put into practical use. In addition, in recent years, in order to reduce the driving burden on the driver, there have been vehicles that automatically perform part of the driving operations such as "running", "turning" and "stopping" instead of t...
