no. 1 Embodiment approach

[0032] First, refer to figure 1 The first embodiment of the present invention will be described.

[0033]

[0034] exist figure 1 The schematic structure of the pseudo-sound generator 700A of 1st Embodiment is shown in FIG. as it should figure 1 As shown, the pseudo sound generator 700A is mounted on the vehicle CR.

[0035] The pseudo sound generator 700A includes a storage unit 710 and a position detection unit 720 . In addition, 700A of pseudo-sound generators include a determination unit 740A, a control unit 750, and a pseudo-sound generation unit 760A.

[0036] Various types of information used in the pseudo sound generator 700A are stored in the storage unit 710 . Such information includes map information. The map information includes road width information and presence / absence information of oncoming traffic lanes.

[0037] The position detection unit 720 detects the current position of the vehicle CR. The current position detected by the position detection un...

no. 2 Embodiment approach

[0058] Next, refer to figure 2 A second embodiment of the present invention will be described.

[0059]

[0060] figure 2 A schematic configuration of a pseudo sound generator 700B according to the second embodiment is shown in . as it should figure 2 As shown, the pseudo-sound generator 700B is mounted on the vehicle CR similarly to the pseudo-sound generator 700A described above.

[0061] The above-mentioned simulated sound generating device 700B differs from the simulated sound generating device 700A in that a determining unit 740B is provided instead of the determining unit 740A, a simulated sound generating unit 760B is provided instead of the simulated sound generating unit 760A, and an acquiring unit 730 is further provided. and a calculation unit 735 . In the following, description will be made focusing on these differences.

[0062] In addition, in the second embodiment, the current position detected by the position detection unit 720 is sent to the calculat...

Embodiment

[0089] Below, refer to Figure 3 ~ Figure 13 An embodiment of the analog sound generating device of the present invention will be described. In addition, in the following description and drawings, the same reference numerals are assigned to the same or equivalent elements, and overlapping descriptions will be omitted.

Abstract

The invention provides an analog sound generating device and an analog sound generating method. According to the current position of a vehicle (CR), a control unit (110) is used for determining whether opposite running lanes exist on a road where the vehicle (CR) is running or not by reference to the information indicating whether the opposite running lanes exist or not in map information (MPD) stored in a storage unit (120). The control unit (110) is used for determining a reaching range of an analog sound output out of the vehicle according to the determined existence or inexistence of the opposite running lanes. Next, the control unit (110) is used for determining set volume of the analog sounds output from a left speaker and a right speaker of an analog sound generating unit (130) according to the determined reaching range. As a result, analog sounds with volume corresponding to the set volume are output out of the vehicle from the left speaker and the right speaker of the analog sound generating unit (130). Therefore, the volume of the analog sounds can be appropriately controlled while the probability that a report object exists in the surroundings, which is changed according to the situation that whether the opposite running lanes exist on the running road, is taken into consideration.

Description

[0001] This application is a divisional application of the original patent application number 201080066971.6 (international application number: PCT / JP2010 / 055169, filing date: March 25, 2010, invention name: analog sound generating device and analog sound generating method) . technical field [0002] The invention relates to an analog sound generating device and an analog sound generating method. Background technique [0003] In recent years, electric vehicles using batteries as a driving force source and hybrid vehicles using batteries as a part of the driving force source have become popular. When such a vehicle runs with a battery as a driving force source, the level of driving sound outside the vehicle is very low compared to conventional gasoline-powered vehicles. As a result, pedestrians or cyclists may not be aware of the presence of a vehicle approaching them from a position out of view such as the rear. The occurrence of the above situation becomes a serious probl...
