[0026] A first embodiment of the present invention will be described below.

[0027] figure 1 is a diagram illustrating the vehicle approach warning system according to the present embodiment. Such as figure 1 As shown in , a pedestrian 2 is walking on the road 1, and a vehicle 3 approaches the pedestrian 2 from behind the pedestrian 2. In this case, if the vehicle running sound is loud enough and the pedestrian 2 has average hearing, the pedestrian 2 can hear the vehicle running sound and notice the approach of the vehicle 3 . In the above, the vehicle 3 may be a hybrid vehicle, an electric vehicle or other motor vehicle. Vehicle driving sound is the sound produced by the vehicle when it is running normally. For example, the vehicle running sound may be engine noise.

[0028] However, hard-of-hearing persons, hearing-impaired elderly people, etc. may not notice the approach of the vehicle 3 . In addition, since vehicles with very little running sound are becoming widely...

[0080] A second embodiment will be described below. Attention will be paid to differences from the first embodiment. This embodiment is substantially the same as the first embodiment in the configuration and operation of the navigation device 5 mounted on the vehicle 3 . That is, the navigation device 5 may have image 3 The configuration illustrated in . Control circuit 57 can perform Figure 4 , Figure 5 The procedure exemplified in et al.

[0081] In this embodiment, the vehicle ID is used as the ID associated with the vehicle, and the control circuit 57 Figure 4 S130 in sending the vehicle ID. The vehicle ID and the vehicle-associated ID are the same in that each of the vehicle-associated ID and the vehicle ID contains data individually assigned to each vehicle for individual vehicle identification. However, the vehicle ID also contains data for the vehicle class to which the vehicle itself belongs.

[0082] Figure 11 is a diagram illustrating the configuration...

Abstract

A vehicle approach warning system is disclosed. The vehicle approach warning system includes: an in-vehicle communication apparatus (5) to be mounted to a vehicle (3), the in-vehicle communication apparatus (5) being configured to wirelessly transmit vehicle travel data to surroundings of the vehicle (3); and a portable warning terminal (4) to be carried by a pedestrian (2), the portable warning terminal (4) being configured to give in response to receiving the vehicle travel data wirelessly transmitted from the in-vehicle communication apparatus (5), and a warning about approach of the vehicle being emitted to the pedestrian (2) in a way other than auditory stimulation if electric field strength at a time of receiving the vehicle travel data is larger than a first threshold (P).

Description

technical field [0001] The present invention relates to a vehicle approach warning system, a portable warning terminal and a vehicle communication device. Background technique [0002] Japanese Unexamined Patent Application Publication No. 2007-182195 discloses a warning system that enables a hearing-impaired person to notice the presence of a warning horn sound when a vehicle emits the warning horn sound. Specifically, when the vehicle emits a warning horn sound, the in-vehicle communication device transmits warning radio waves to the surroundings. When the portable warning terminal carried by the hearing-impaired person receives this radio wave, the portable warning terminal vibrates a vibrator or emits a warning colored light. [0003] The inventors of the present application have found the following facts. The situation requiring a warning to a person is not limited to only when the vehicle sounds the warning horn. For example, when a vehicle approaches the person fro...
