Problems solved by technology

If people around the vehicle are late aware of the presence of the vehicle or start to move when the vehicle starts, there is a possibility of people accidentally approaching the vehicle
[0021] In addition, if vehicles that generate sounds other than running noise travel in groups, the sounds generated by the individual vehicles overlap with each other and may be unpleasant to surrounding people.
For example, in a quiet residential area, etc., such a situation may worsen the residential environment

[0209]As shown in FIG. 1 , a hybrid vehicle 1000 is mounted with a vehicle warning device 610 according to the present embodiment, a motor generator (hereinafter abbreviated as MG) (1) 200, a PCU (Power Control Unit) 300, a battery as a power storage device 400, MG (2) 500, communication device 650, display device 660, and HV-ECU (Hybrid Vehicle Electronic Control Unit) 600 connected to all of the above components.

[0210] The engine 100 combusts an air-fuel mixture of fuel and air and rotates a crankshaft (not shown) to generate driving force. The driving force generated by engine 100 is divided into two paths by power split device 700 . One of them is a path for driving the wheels 900 through the speed reducer 800 . The other is a path for driving MG(1) 200 to generate electric power.

[0211] MG (1) 200 is driven by the mechanical power of engine 100 distributed by power split device 700 to generate electric power. Electric power generated by MG ( 1 ) 200 is appropriate...

Abstract

A warning device (610) includes a horn A (630) for generating a first warning having a sound volume satisfying the legal standard and a horn B (632) for generating a second warning having a sound volume not greater than the first horn or a type different from the first horn.

Description

technical field [0001] The present invention relates to vehicle warning devices, and more particularly to warning devices for attracting the attention of persons around a vehicle. Background technique [0002] Conventionally, a vehicle is equipped with a warning device for generating a warning of other vehicles, pedestrians, etc. around the vehicle. The volume of the warning is set to a level that satisfies legal standards in such a way that drivers in other vehicles can be aware of the purpose of the warning. As a result, pedestrians may perceive the volume as too loud in some cases. [0003] In consideration of this problem, there are vehicle audio alarm devices for automobiles and the like, for example, as disclosed in Japanese Utility Model Registration No. 3094635, in which the volume can be adjusted to generate sound in an arbitrary volume range according to time and place. This vehicle audio alarm includes: a main audio alarm for producing a sound at a volume set in...
