Abstract

The invention provides an attention reminding device and an attention reminding method, which enable a driver of a vehicle to intuitively recognize that the level of risk is changed in a scene of outputting sounds of a plurality of languages in a short period of time. The attention device (100) is provided with a risk index value acquisition unit (132) that acquires a risk index value indicating the risk of collision between an object existing in front of a vehicle (1) and the vehicle (1) on the basis of the outputs of a plurality of sensors mounted on the vehicle (1), and a notification control unit (135) that, when an object whose risk index value is equal to or greater than a preset first threshold value is detected, outputs a voice to notify the driver of the vehicle of the object, and, when the risk index value is equal to or greater than a preset second threshold value during notification of the object to the driver of the vehicle by the output of the voice, notifies the driver of the vehicle that the risk index value has changed by a method other than voice-based notification.

Claims (4)

1. An attention reminding device, comprising: an index value acquisition unit that acquires, based on outputs from a plurality of sensors mounted on a vehicle, a risk index value indicating a risk of collision between an object existing in front of the vehicle and the vehicle, and And a notification control unit that, when an object whose risk index value is equal to or greater than a first threshold value set in advance is detected, outputs a voice of a language to notify the driver of the vehicle of the object, and when the risk index value is equal to or greater than a second threshold value set in advance during notification of the object to the driver of the vehicle by the output of the voice of the language, notifies the driver of the vehicle that the risk index value has changed by a method other than notification based on the voice of the language.
2. The attention device of claim 1 wherein, When the risk index value is lower than the first threshold value, the notification control unit ends the notification of the sound based on the language, and notifies the driver of the vehicle that the risk index value has changed by a method other than the notification of the sound based on the language.
3. The attention device of claim 1 or 2, wherein, The notification control unit notifies the driver of the vehicle that the risk index value has changed, by display by a visual human-machine interface device or vibration by a tactile human-machine interface device.
4. In an attention reminding method, a processor of an attention reminding device mounted on a vehicle is caused to execute the steps of: Acquiring a risk index value indicating a risk of collision between an object existing in front of a vehicle and the vehicle based on outputs of a plurality of sensors mounted on the vehicle; outputting a voice of a language to notify a driver of the vehicle of the object when the risk index value is detected to be the object of the preset first threshold value or more, and When the risk index value is changed by a predetermined second threshold value or more during the notification of the object to the driver of the vehicle by the output of the voice of the language, the risk index value is notified to the driver of the vehicle that the change has occurred by a method other than the notification based on the voice of the language.

Description

Attention reminding device and attention reminding method Technical Field The invention relates to an attention reminding device and an attention reminding method. Background In recent years, a system for notifying a risk to a driver of a vehicle by a plurality of HMI (Human MACHINE INTERFACE: human machine interface) devices has been known. For example, the driving support device disclosed in patent document 1 includes a notification unit that acquires object information including a position, a traveling direction, and a vehicle speed of another vehicle, detects traveling information including the position, the traveling direction, and the vehicle speed of the own vehicle, and notifies the vehicle based on the detected information. The driving support device includes a display device for displaying a positional relationship between the vehicle and the other vehicle on a map, and a speaker for outputting a sound corresponding to the risk level as notification means. The information providing apparatus disclosed in patent document 2 further includes an output control unit that outputs audio output information and displays display output information generated based on at least a part of the audio output information immediately before the audio output information is output. The display output information is displayed and output for a predetermined time immediately before the audio output information corresponding to the display output information is output. [ Prior Art literature ] [ Patent literature ] [ Patent document 1] Japanese patent laid-open No. 2002-342899 [ Patent document 2] Japanese patent laid-open No. 2005-352645 Disclosure of Invention [ Problem to be solved by the invention ] However, when a plurality of pieces of information are notified to a driver in driving only by sound, a plurality of sounds are output in a short period of time, and therefore there is a problem to be improved in terms of ease of visual understanding. The present application is to solve the above problems and to improve the discrimination. Furthermore, the development of a continuous transportation system is facilitated by further improving the traffic safety. [ Means for solving the problems ] An attention device according to one aspect of the present invention includes an index value acquisition unit that acquires, based on outputs of a plurality of sensors mounted on a vehicle, a risk index value indicating a risk of collision between an object existing in front of the vehicle and the vehicle, and a notification control unit that, when an object whose risk index value is equal to or greater than a first threshold value set in advance is detected, outputs a voice to notify the driver of the vehicle of the object, and when the risk index value is equal to or greater than a second threshold value set in advance in notifying the driver of the vehicle by the output of the voice, notifies the driver of the vehicle that the risk index value has changed by a method other than notification based on the voice. In another aspect of the present invention, the notification control unit ends the notification of the sound based on the language when the risk index value is lower than the first threshold value, and notifies the driver of the vehicle that the risk index value has changed by a method other than the notification of the sound based on the language. In another aspect of the present invention, the notification control unit notifies the driver of the vehicle that the risk index value has changed by display by the visual HMI device or vibration by the tactile HMI device. Another aspect of the present invention is a method for reminding a driver of a vehicle, wherein a processor of an attention reminding device mounted on the vehicle is caused to execute the steps of acquiring a risk index value indicating a risk of collision between an object existing in front of the vehicle and the vehicle based on outputs of a plurality of sensors mounted on the vehicle, notifying the object to the driver of the vehicle by outputting a voice of a language when the risk index value is detected as the object equal to or higher than a first threshold value set in advance, and notifying the driver of the vehicle that the risk index value has changed by a method other than the notification based on the voice of the language when the risk index value has changed by a second threshold value set in advance in notifying the object to the driver of the vehicle by the output of the voice of the language. [ Effect of the invention ] According to one aspect of the present invention, in a scene in which sounds of a plurality of languages are output in a short period of time, it is possible to intuitively recognize that the level of risk has changed by the driver of the vehicle.
