Description

FIELD

Embodiments of the present disclosure generally relate to the field of electric vehicles. More specifically, embodiments of the disclosure relate to an apparatus and methods for a sound generator for an electric vehicle that enables a driver to select and manipulate the sounds emitted outside the vehicle.

BACKGROUND

As the world attempts to move away from burning fossil fuels, electric vehicles (EVs) are gaining in popularity as a more sustainable alternative. However, EVs are not without certain difficulties. Once such difficulty has been the quietness of the electric motor comprising EVs. Pedestrians generally are accustomed to the sounds emitted by fossil fuel-burning vehicles, but the subdued sounds of many EVs have made it difficult for pedestrians to hear approaching EV traffic. These difficulties have been especially challenging for the visually impaired community.

In an attempt to make EVs discernable to visually impaired pedestrians, some nations have created electric car noise laws. Such laws generally require all new EVs, including hybrid vehicles, to have a noise-emitting device. For example, the European Union requires new EVs to be fitted with an acoustic vehicle alert system (AVAS), which makes a sound similar to a traditional engine to warn nearby pedestrians. The AVAS is required to sound when an EV is reversing as well as when travelling at less than 18.6 mph (30 km/h). Further, the minimum sound requirements for hybrid and EVs are that a pedestrian should be able to hear the EV over background noises.

Given the increasing popularity of EVs, there is a desire to develop and improve sounds associated with the operation of EVs that are discernable by pedestrians. Embodiments herein provide a sound generator for EVs that enables a driver to select and manipulate the sounds emitted outside the EV.

DETAILED DESCRIPTION

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. It will be apparent, however, to one of ordinary skill in the art that the EV sound effect generation system and methods disclosed herein may be practiced without these specific details. In other instances, specific numeric references such as “first generator,” may be made. However, the specific numeric reference should not be interpreted as a literal sequential order but rather interpreted that the “first generator” is different than a “second generator.” Thus, the specific details set forth are merely exemplary. The specific details may be varied from and still be contemplated to be within the spirit and scope of the present disclosure. The term “coupled” is defined as meaning connected either directly to the component or indirectly to the component through another component. Further, as used herein, the terms “about,” “approximately,” or “substantially” for any numerical values or ranges indicate a suitable dimensional tolerance that allows the part or collection of components to function for its intended purpose as described herein.

As the world moves away from burning fossil fuels, electric vehicles (EVs) are gaining in popularity as a more sustainable alternative. However, the quietness of the electric motors comprising EVs make it difficult for pedestrians, especially visually impaired pedestrians, to hear approaching EV traffic. In an attempt to make EVs discernable to visually impaired pedestrians, there is a desire to require EVs, including hybrid vehicles, to include a noise-emitting device. Such a noise-emitting device preferably produces sound when the EV is reversing as well as when travelling at relatively slow speeds. Given the increasing popularity of EVs, there is a desire to develop and improve sounds associated with the operation of EVs that are discernable by pedestrians. Embodiments herein provide a sound generator for EVs that enables a driver to select and manipulate the sounds emitted outside the EV.

FIG. 1 is a schematic illustrating an exemplary embodiment of EV sound effect generation system 100 in accordance with the present disclosure. The EV sound generation system 100 comprises a sound generator system 104 stored on a non-transient machine-readable medium (i.e., a memory) of an application server system 108 which comprises at least one processor and has connectivity to a wireless sound generator module 112 that is connected to a vehicle 116. Generally, the wireless sound generator module 112 simulates an engine sound when the vehicle 116 is operating. The engine sound is emitted outside the vehicle 116 by way of a boost speaker 120. When the vehicle 116 is turned on and remaining stationary, the engine sound resembles an idling internal combustion engine. When the speed of the vehicle 116 increases, however, the engine sound simulates revving of the internal combustion engine and shifting of a transmission (not shown). Further, the engine sound simulates a decelerating internal combustion engine sound when the speed of the vehicle 116 is decreasing.

In an exemplary embodiment, illustrated in FIG. 4, the EV sound effect generation system 100 includes the wireless sound generator module 112, the boost speaker 120, an external GPS antenna 124, and a wiring harness 128. The boost speaker 120 preferably is enclosed in a suitable housing for being mounted outside the vehicle 116 and protecting the speaker 120 from potential environmental damage. Further, the external GPS antenna 124 is configured to be installed onto a location of the vehicle 116 that is suitable for receiving “global positioning system” (GPS) data. In some embodiments, the external GPS antenna 124 is configured to be installed outside the vehicle 116, as shown in FIG. 1. The wireless sound generator module 112 is configured to determine the speed of the vehicle 116 by way of the external GPS antenna 124 and one or more internal accelerometers. An accurate measure of the speed of the vehicle 116 enables the wireless sound generator module 112 to simulate engine revving and transmission shifting, as described herein.

As will be appreciated, the wiring harness 128 is configured to electrically couple the EV sound effect generation system 100 with the vehicle 116. In the illustrated embodiment, the wiring harness 128 includes an antenna cable 132, power wires 136, and speaker wires 140. The antenna cable 132 is configured to couple the external GPS antenna 124 with the wireless sound generator module 112. The power wires 136 are configured to be connected to a source of DC electrical power source onboard the vehicle 116 such as by way of an electrical system comprising the vehicle 116. As such, the power wires 136 generally comprise a power wire 144 and a ground wire 148 for respectively connecting to a positive (+) terminal of the vehicle's battery and a negative (−) terminal of the battery. Further, the speaker wires 140 generally are configured for conducting electrical signals from the wireless sound generator module 112 to the boost speaker 120 comprising sound effects to be broadcast by the speaker 120.

As described herein, the wireless sound generator module 112 is configured to establish wireless communication with sound generator system 104 (see FIG. 1) by way of a mobile application 152 or an application server system 108 as shown in FIG. 1. In some embodiments, the sound generator system 104 comprises an interface 160 that provides access to a component systems package 164. A host site 168 provides a multiplicity of end-users 172 access to the application server system 108 by way of a communications network, such as the Internet. The end-users 172 may comprise vehicle drivers or vehicle servicing personnel, such as, by way of example, auto mechanics, technicians, vehicle owners, and the like, desiring to access and interact with sound effects to broadcast outside vehicles.

In some embodiments, the host site 168 comprises a web-based application whereby the end-users 172 interact with the component systems package 164. In some embodiments, the host site 168 may comprise a customized web-based mobile device application which enables service personnel and vehicle owners to directly interact with the component systems package 164. In some embodiments, the host site 168 and the sound generator system 104 may comprise a software application configured to operate on a mobile device and communicate with the wireless sound generator module 112 by way of a wireless connection. In such embodiments, the end-user 172 installs the wireless sound generator module 112 into the vehicle 116 and establishes a wireless connection between the wireless sound generator module 112 and a mobile device, such as a cellphone 176, as shown in FIG. 2. It is contemplated that the wireless connection between the sound generator module 112 and the cellphone 176 may comprise any wireless protocol suitable for transferring data, including any of Bluetooth, WiFi, NFC, and the like, without limitation.

It is contemplated that, in some embodiments, each of the end-users 172 may utilize applications stored on the memory of the application server system 108 to send demand signals, or “electronic orders,” to one or more of various content suppliers 180 so as to receive desired sound effects and other upgrades. The content suppliers 180 may comprise organizations, such as, by way of example, suppliers of sound effects files, firmware updates, application downloads, and the like. In some embodiments, the component systems package 164 is stored on the memory of the application server system 108, and the interface 160 is a software application which comprises a portion of the sound generator system 104, thereby providing access to the component systems package 164. In some embodiments, the component systems package 164 comprises functions that are performed by the wireless sound generator module 112 while the interface 160 is a software application that provides wireless access to settings that control the functions performed by the component systems package 164. In some embodiments, the component systems package 164 may be services operated by one or more third-party service providers. In such embodiments, the interface 160 may comprise a connection over the communications network, such as an Internet connection, whereby the application server system 108 may send requests to, and receive services from, the one or more third-party service providers.

As will be appreciated, the component systems package 164 generally comprises component systems whereby each end-user 172 may interact with sound effects provided by way of the wireless sound generator module 112. FIG. 3A illustrates an exemplary embodiment of a touch screen 184 that may be presented to the end-user 172, by way of the cellphone 176, whereby the component systems package 164 may be accessed. For example, the touch screen 184 may include various controls that enable the end-user 172 to select and operate sound effects by way of the component systems comprising the package 164. In the illustrated embodiment of FIG. 1, the component systems package 164 includes an engine rev system 188, a minimal operational voltage system 192, a wake-up system 196, a sound file header information read system 200, and a download system 204. In some embodiments, however, the component systems package 164 may comprise other systems in addition to the component systems illustrated in FIG. 1, without limitation and without deviating beyond the spirt and scope of the present disclosure. Each of the systems comprising the component systems package 164 is described below.

The engine rev system 188 generally is configured to enable a driver of the vehicle 116 to select and control sound effects to be broadcast outside the vehicle 116. For example, an exemplary embodiment of the engine rev system 188 that may be displayed to the end-user 172 by way of the cellphone 176 is shown in FIGS. 3A and 3B. As shown in FIG. 3A, the touch screen 184 includes buttons 208 that enable the driver to play a sound effect, pause the current sound effect, and select a difference sound effect to play. A volume slider 212 enables the driver to alter the volume of the sound emitted outside the vehicle 116. An upper portion of the touch screen 184 displays a simulated engine performance dial 216. The simulated engine performance dial 216 displays a current engine RPM and speed of the vehicle 116 that corresponds to the current sound effect being broadcast outside the vehicle 116. An output pane 220 displays a graph indicating previously simulated engine performance and vehicle speeds that has been displayed during the current driving session.

FIG. 3B illustrates an exemplary embodiment of the touch screen 184 during a relatively performance engine simulation. As will be appreciated, the simulated engine performance dial 216 shown in FIG. 3B displays an engine RMP and speed of the vehicle 116 that are much higher that the engine RMP and speed shown in FIG. 3A. Further, the output pane 220 shown in FIG. 3B indicates a relatively high-performance simulated engine output and vehicle 116 speed has occurred during the current driving session. Accordingly, the touch screen 184 shown in FIG. 3B indicates that the engine sound being broadcast outside the vehicle 116 corresponds to high performance engine revving and gear shifting. The touch screen 184 shown in FIG. 3A indicates that the engine sound being broadcast outside the vehicle 116 corresponds to lower engine speeds and relatively gentle gear shifting.

As shown in FIGS. 3A and 3B, the touch screen 184 includes one or more navigation buttons 224 that enable the driver to interact with the engine rev system 188. For example, in some embodiments, the driver may toggle between several different engine sounds. In some embodiments, the driver may broadcast a revving engine sound by touching an Engine Rev button (not shown). Further, the buttons 224 may enable the driver to initiate sound file downloads and firmware updates, as needed. Other functions of the navigation buttons 224 will be apparent to those skilled in the art without deviating beyond the spirit and scope of the present disclosure.

Turning, again, to FIG. 1, the minimum operational voltage system 192 is configured to detect an operational voltage available to the system 100 and ensure that the wireless sound generator module 112 does not fully function when the operational voltage drops below a minimal value. In some embodiments, the minimal operational voltage system 192 comprises a portion of the wireless sound generator module 192. In such embodiments, the minimum operational voltage system 192 remains functional and detects available voltage values in absence of the cellphone 176. In some embodiments, the minimum operational voltage system 192 is configured to put the wireless sound generator module 112 into a sleep mode when the available voltage drops to a minimal value, such as when the vehicle 116 is turned off.

The wake-up system 196 is configured to wake the wireless sound generator module 112 from a low-current, sleep mode so that it can function normally. For example, when the vehicle 116 is turned on, the wake-up system 196 detects that the vehicle 116 is operating and wakes the wireless sound generator module 112 from the sleep mode. The wireless sound generator module 112 may then broadcast a selected engine sound. In some embodiments, the wake-up system 196 comprises a portion of the wireless sound generator module 112 and thus is operable in absence of the cellphone 176 shown in FIG. 2. In some embodiments, however, the wake-up system 196 comprises an external, remote-mount module configured to wake up the wireless sound generator module 112 in absence of the cellphone 176.

The sound file header information read system 200 is configured to read information included in the header portion of sound files so as to improve sound quality and make sound effects more realistic. For example, sound file header information may include information pertaining to any one or more of maximum engine RPM, minimum engine RPM, shift points, shift delays, maximum volume, treble adjustments, bass adjustments, and the like, without limitation. In some embodiments, the sound file header information read system 200 may be configured to read sound file header information and then automatically trim treble and bass of sound effects in response to particular combinations of boost speakers 120, speaker enclosures, and sound files, without limitation.

The download system 204 is configured to enable the end-user 172 to obtain new sound files and firmware updates quickly and easily, as needed. In some embodiments, when the end-user 172 selects a sound file to download, the download system 204 directs the cellphone 176 to a website related to one of the content suppliers 180 whereby the end-user 172 may obtain new sound files and/or firmware updates. For example, when the end-user 172 selects a desired sound effect file, the download system 204 redirects the cellphone 176 to the website of the content supplier 144 that sells or otherwise offers the desired sound effect file for download. As will be appreciated, once the cellphone 176 is redirected to the website, the end-user 172 may obtain the sound effect file, as desired.
