Problems solved by technology

[0003] However, if data obtained using a vehicle (or model vehicle) different from that of the intended vehicle type is used as engine sound data, the speed range of the model vehicle, the area and change characteristics of the number of engine revolutions, the change in the accelerator opening characteristics etc. may not correspond to these parameters for the vehicle being targeted and no advice has been given on how to synthesize the desired engine sound

Embodiment Construction

[0029] attached figure 1 is a block diagram showing the overall configuration of the engine sound generating device 10 according to the embodiment of the present invention. The engine sound generating device 10 includes a detection section group 20, a storage section 30, a processing section 40, an engine sound generating section 50, and an operating section 60, and the engine sound generating device 10 generates an engine sound using these components. The detecting section group 20 includes a vehicle speed detecting section 210 for detecting the traveling speed of the vehicle (hereinafter referred to as "vehicle speed") and an acceleration detecting section 220 for detecting the acceleration of the vehicle. For example, the vehicle speed detecting part 210 includes a sensor for detecting the number of revolutions of the propeller shaft installed on the propeller shaft, which rotates the wheels in response to the operation of the prime mover of the vehicle. The vehicle speed ...

Abstract

The present invention provides an engine sound generation apparatus and method. Change tendency data, indicative of a change tendency of a vehicle velocity, is obtained on the basis of acquired velocity information. Correction value of an accelerator opening degree is generated in accordance with the change tendency data and a current value of the accelerator opening degree is updated using the correction value, so that the accelerator opening degree is estimated. Then, engine sound data having a characteristic corresponding to the estimated accelerator opening degree are generated. When there has been a shift change, the current value of the accelerator opening degree, stored in the storage section, is updated to become a predetermined value, without the correction value being used.

Description

technical field [0001] The present invention relates to an engine sound generating device and method. Background technique [0002] An apparatus that generates an engine sound of a vehicle or the like using parameters such as a detected accelerator opening, engine speed, and the like is already known. For example, the apparatus disclosed in Japanese Patent Application Laid-Open No. 2000-010576 is configured to generate synthesized sound data of an engine sound from data of a throttle opening degree and data of an engine rotational speed. [0003] However, if data obtained using a vehicle (or model vehicle) different from that of the intended vehicle type is used as engine sound data, the speed range of the model vehicle, the area and variation characteristics of the number of engine revolutions, the variation of the accelerator opening Characteristics, etc. may not correspond to these parameters for the intended vehicle, and no opinion is given on how to synthesize the desi...
