Problems solved by technology
[0007] However, in the "Pedestrian Friendly" alarm system, pedestrians, etc. are detected by the sensor of the own vehicle, and therefore pedestrians, etc., cannot be detected if the pedestrians, etc., exist in the blind spot of the sensor.
Therefore, there is a problem that the warning sound is not output even when pedestrians and the like are around the own vehicle, and the attention of the pedestrians and the like cannot be called.
[0008] In addition, in the technique of Patent Document 1, there is a problem that it is impossible to perform simulated driving based on the actual situation when the positioning accuracy of the own vehicle position is not good or when the actual road shape is changed and the map information is wrong. sound output

Embodiment Construction
[0045] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 It is a block diagram showing a schematic configuration of a simulated running sound generating system 100 to which the present invention is applied. Such as figure 1 As shown, the simulated driving sound generating system 100 includes: a simulated driving sound generating device 1 , a portable terminal 2 and a roadside device 3 .
[0046] The simulated running sound generator 1 is mounted on an electric vehicle such as an electric vehicle (EV) or a hybrid electric vehicle (HEV) that uses an electric motor (motor) as a driving source (driving force source) for driving. In this embodiment, if figure 1 As shown, for example, the electric vehicle A and the electric vehicle B are respectively equipped with the simulated running sound generator 1 to continue the description.
[0047] The portable terminal 2 is a terminal carried by pedestrians, light vehicle driver...

Provided is a simulated Driving sound generating device and a simulated driving sound generating system. The simulated driving sound is output based on a simulated driving sound output request information which is sent under the situation that the simulated driving sound generating device (1) loaded to an electric vehicle can communicate with the simulated driving sound generating device (1) of a portable terminal (2), a road side machine (3) and other vehicles disposed outside of the electric vehicle, and is relevant to the output of the simulated driving sound. In this case, the simulated driving sound output can not be influenced by factors like a blind angle of a danger object detection device (12) for detecting the danger object, and the simulated driving sound can be output under the situation that danger objects exist around the vehicle and that the possibility of danger objects existing around the vehicle is high.
Description
technical field [0001] The invention relates to a device for generating simulated running sound and a system for generating simulated running sound. Background technique [0002] Conventionally, electric vehicles (EVs) and hybrid electric vehicles (HEVs) using electric motors (motors) as driving sources are known. EVs and HEVs (hereinafter referred to as electric vehicles) are low-noise, and therefore it is difficult for pedestrians passing around a running or parked electric vehicle to predict in advance the possibility of approaching or starting of the electric vehicle. On the other hand, the possibility of making pedestrians and the like notice the approaching and starting of the electric vehicle by outputting a simulated running sound (hereinafter referred to as simulated running sound) from the electric vehicle is considered. [0003] However, it is not preferable to always output the analog running sound from the viewpoint of noise and battery consumption. Therefore,...
