Detailed Description

[00014] FIGS. 1 -6 illustrate various embodiments of a sound feedback system 10 for providing a feedback sound representative of a vehicle. With reference to FIG. 1 , in one embodiment the illustrated sound feedback system 10 is configured for providing a feedback sound 15 representative of a first vehicle status 20 of a first vehicle electronics 25 of a first vehicle 27 (e.g., tractor, combine, construction vehicle) and a second vehicle status 30 of a second vehicle electronics 35 of a second vehicle 37 (e.g., tractor, combine, construction vehicle).

[00015] The sound feedback system 10 comprises a first vehicle data bus 40 of the first vehicle electronics 25. For example, the first vehicle data bus 40 may be a first CAN bus 45. A first sound sensor 50, or a first engine RPM sensor 55, a first diagnostic module 60, a first controller 65, or other first device 70 (e.g., engine controller, transmission controller, controller, other sensor, network element), may be in communication with the first vehicle data bus 40 to collect and provide first vehicle sound 75 (e.g., ambient sound, engine sound, combine separator).

[00016] For instance, the first diagnostic module 60 is capable of producing diagnostic codes, alarm data, warning data, trouble codes or status messages as the first vehicle sound 75. The first diagnostic module 60 may be configured to determine whether the first vehicle electronics 25 of the first vehicle 27 is operating properly.

[00017] The sound feedback system 10 comprises a second vehicle data bus 80 of the second vehicle electronics 35. For example, the second vehicle data bus 80 may be a second CAN bus 85. A second sound sensor 90, or a second engine RPM sensor 95, a second diagnostic module 100, a second controller 105, or other second device 1 10 (e.g., engine controller, transmission controller, controller, other sensor, network element), may be in communication with the second vehicle data bus 80 to collect and provide second vehicle sound 1 15 (e.g., ambient sound, engine sound, combine separator).

[00018] For instance, the second diagnostic module 100 is capable of producing diagnostic codes, alarm data, warning data, trouble codes or status messages as the second vehicle sound 1 15. The second diagnostic module 100 may be configured to determine whether the second vehicle electronics 35 of the second vehicle 37 is operating properly.

[00019] A first wireless communication device 120 is in communication with the first vehicle data bus 40. The first wireless communication device 120 is configured to communicate the first vehicle sound 75. The first wireless communication device 120 may be a first transceiver 125 or a first transmitter 130.

[00020] A second wireless communication device 135 is in communication with the second vehicle data bus 80. The second wireless communication device 1 35 is configured to communicate the second vehicle sound 1 15. The second wireless communication device 135 may be a second transceiver 140 or a second transmitter 145.

[00021] An electronic data processing system 150 is configured to receive the first vehicle sound 75 and the second vehicle sound 1 15 from the first vehicle data bus 40 and the second vehicle data bus 80 via the first wireless communication device 120 and the second wireless communication device 135, respectively. The electronic data processing system 150 may comprise a third wireless communication device 155 to communicate with the first wireless communication device 120 and the second wireless communication device 1 35. The third wireless communication device 155 may be a third transceiver 160 or a receiver 165.

[00022] In one embodiment, a sound integration module 170 comprises one or more amplifiers, attenuators, combiners, mixers, multipliers, frequency shifters, analog-to-digital converters, digital-to-analog converters, software emulators, software modules, or electronic modules for processing vehicle status data or vehicle sounds in the analog or digital domain. In one configuration, the sound integration module 170 is adapted to derive, form, or create synthetically-created sounds from one or both of the first vehicle status 20 and the second vehicle status 30, first vehicle sound 75, second vehicle sound 1 15, data diagnostic codes, alarm data, warning data, or trouble codes from one or both of the first vehicle electronics 25 and the second vehicle electronics 35, for example.

[00023] In an alternate configuration, the sound integration module 170 is capable of generating, combining (equally or weighted), mixing, amplifying, attenuating, frequency shifting, multiplying, creating (e.g., synthetically-derived or synthetically- created vehicle sounds), or processing sounds (e.g., recorded sounds)

representative of an operational or functional status of the first vehicle electronics 25, the second vehicle electronics 35, or both.

[00024] The sound integration module 170 is configured to form or determine the feedback sound 15 from the first vehicle sound 75 and the second vehicle sound 1 15. The sound integration module 170 may match the first vehicle sound 75 and the second vehicle sound 1 15 to a library of feedback sounds 175 and communicate the feedback sound 15.

[00025] The sound integration module 170 may be configured to determine whether the first vehicle electronics 25 and the second vehicle electronics 35 are operating properly and form the feedback sound 15 as a dissonant chord 180 if at least one of the first vehicle electronics 25 and the second vehicle electronics 35 is not operating properly and form the feedback sound 15 as a major chord 185 if the first vehicle electronics 25 and the second vehicle electronics 35 are operating properly. The determination of whether the first vehicle electronics 25 and the second vehicle electronics 35 are operating properly may be determined by a threshold deviation between an expected and actual first vehicle sound 75 and second vehicle sound 1 15.

[00026] The sound integration module 170 may be configured to determine whether the first vehicle electronics 25 and the second vehicle electronics 35 are operating properly and form the feedback sound 15 in an amplified manner 190 if at least one of the first vehicle electronics 25 and the second vehicle electronics 35 is not operating properly and form the feedback sound 15 in a non-amplified manner 195 if the first vehicle electronics 25 and the second vehicle electronics 35 are operating properly.

[00027] A sound generator module 200 is configured to communicate the feedback sound 15 to a user 205. The sound integration module 170 and the sound generator module 200 may be separate electronic hardware modules or software included in a memory 210 of a data storage 215 of the electronic data processing system 150.

[00028] Alternatively, the sound generator module 200 may be configured to determine whether the first vehicle electronics 25 and the second vehicle electronics 35 are operating properly and generate a first tone 220 representative of the first vehicle sound 75 and a second tone 225 representative of the second vehicle sound 1 15. If at least one of the first vehicle electronics 25 and the second vehicle electronics 35 is not operating properly, the first tone 220 and the second tone 225 may be on different frequencies or spaced apart in the frequencies of a minor chord 230 or a dissonant sound 235. If the first vehicle electronics 25 and the second vehicle electronics 35 are operating properly, the first tone 220 and the second tone 225 may be on the same frequency or spaced on frequencies that form notes of the major chord 185. In addition, the feedback sound 1 5 may comprise a voice recording 240 if at least one of the first vehicle electronics 25 and the second vehicle electronics 35 is not operating properly. For example, the voice recording 240 may state "check engine" or other phrases.

[00029] Alternatively, if the first vehicle electronics 25 of the first vehicle 27 is not operating properly, the sound generator module 200 may form the feedback sound 15 to more closely approximate a sound representative of the first vehicle sound 75. If the second vehicle electronics 35 of the second vehicle 37 is not operating properly, the sound generator module 200 may form the feedback sound 15 to more closely approximate a sound representative of the second vehicle sound 1 15.

[00030] In another embodiment, if at least one of the first vehicle electronics 25 and the second vehicle electronics 35 is not operating properly, the sound generator module 200 is configured to form the feedback sound 15 in the amplified manner 190. However, if the first vehicle electronics 25 and the second vehicle electronics 35 are operating properly, the sound generator module 200 is configured to form the feedback sound 15 in the non-amplified manner 195.

[00031] Alternatively, if the first vehicle electronics 25 of the first vehicle 27 is not operating properly, the sound generator module 200 may form the feedback sound 15 from the first vehicle sound 75 modified by an alteration factor 242 (e.g., altering a sound amplification factor, altering a sound frequency offset, altering a sound frequency multiplier, changing the shape of a waveform by a mathematical function, substituting a sound, or substituting speech) and the second vehicle sound 1 15. If the second vehicle electronics 35 of the second vehicle 37 is not operating properly, the sound generator module 200 may form the feedback sound 15 from the first vehicle sound 75 and the second vehicle sound 1 1 5 modified by the alteration factor 242.

[00032] A user interface 245 comprising a speaker 250 may be in communication with the sound generator module 200. The user interface 245 is configured to communicate the feedback sound 15 through the speaker 250. The user interface 245 may provide additional detail on a display 255 (e.g., LCD screen).

[00033] Alternatively, the user interface 245 may comprise a first speaker 260 and a second speaker 265. The user interface 245 may be configured to communicate the feedback sound 15 representative of the first vehicle status 20 of the first vehicle electronics 25 primarily through the first speaker 260 and the feedback sound 15 representative of the second vehicle status 30 of the second vehicle electronics 35 primarily through the second speaker 265. This enables a stereo effect, where an illusion of directionality and audible perspective is provided, when the first vehicle electronics 25 and the second vehicle electronics 35 are positioned left and right of one another, the first speaker 260 and the second speaker 265 are positioned left and right of one another, and the feedback sound 15 representative of the vehicle on the left is communicated primarily through the speaker on the left and the feedback sound 15 representative of the vehicle on the right is communicated primarily through the speaker on the right, depending on the relative position of the first vehicle electronics 25 and the second vehicle electronics 35. Once the first vehicle electronics 25 and the second vehicle electronics 35 are positioned adjacent one another, the feedback sound 15 representative of the vehicle on the left and the vehicle on the right may be the same in the first speaker 260 and the second speaker 265. The stereo effect is also possible when the first vehicle electronics 25 and the second vehicle electronics 35 are positioned front and rear of one another, the first speaker 260 and the second speaker 265 are positioned front and rear of one another, and the feedback sound 1 5 representative of the vehicle in the front is communicated primarily through the speaker in the front and the feedback sound 15 representative of the vehicle in the rear is communicated primarily through the speaker in the rear, depending on the relative position of the first vehicle electronics 25 and the second vehicle electronics 35. Once the first vehicle electronics 25 and the second vehicle electronics 35 are positioned adjacent one another, the feedback sound 15 representative of the vehicle in front and the vehicle in the rear may be the same in the first speaker 260 and the second speaker 265. Other vehicle and speaker configurations are contemplated by this disclosure.

[00034] Referring to FIG. 2, in another embodiment, the illustrated feedback system 10 is configured for providing the feedback sound 15 representative of the first vehicle status 20 of the first vehicle electronics 25 (e.g., tractor, combine, construction vehicle) and the second vehicle status 30 of the second vehicle electronics 35 (e.g., tractor, combine, construction vehicle) working together in a work area 270. The feedback system 10 of FIG. 2 is similar to the feedback system 10 of FIG. 1 , except that the feedback sound 15 is provided to a user 205 of the first vehicle 27, such as within a cab or at the user interface 245 of the first vehicle 27. Like reference numbers in FIG. 1 and FIG. 2 indicate like elements.

[00035] The feedback system 10 comprises the first vehicle data bus 40 of the first vehicle electronics 25. The first wireless communication device 120 is in

communication with the first vehicle data bus 40. The first wireless communication device 120 is configured to receive second vehicle sound 1 15 from the second wireless communication device 135 of the second vehicle electronics 35. In the first vehicle electronics 25, the electronic data processing system 150 is configured to receive the first vehicle sound 75 and the second vehicle sound 1 15. The sound integration module 170 is capable of forming or determining the feedback sound 15 from the first vehicle sound 75 and the second vehicle sound 1 15. The sound generator module 200 is configured to communicate the feedback sound 15 to the user 205.

[00036] With reference to FIG. 3, the first vehicle electronics 25 may be supported on a lead vehicle 275 (e.g., combine). The lead vehicle 275 may comprise a lead implement 280 (e.g., header). The second vehicle electronics 35 may be supported on a follower vehicle 285 (e.g., combine) configured to follow the lead vehicle 275. The follower vehicle 285 may comprise a follower implement 290 (e.g., header). It is contemplated that the lead vehicle 275 may operate in front of, behind, to the left, or to the right of the follower vehicle 280. The electronic data processing system 150 may be coupled to the lead vehicle 275. The first vehicle sound 75 (FIG. 2) may pertain to the lead implement 280. The second vehicle sound 1 15 (FIG. 2) may pertain to the follower implement 290.

[00037] Referring to FIG. 4, a flow chart of the steps of the method for providing sound feedback to a user or manager of one or more vehicles is disclosed according to one embodiment. In step 295, the first vehicle sound 75 is communicated. In step 300, the second vehicle sound 1 15 is communicated. In step 305, the first vehicle sound 75 and the second vehicle sound 1 15 are received by an electronic data processing system 150. In step 310, the feedback sound 15 is formed or determined from the first vehicle sound 75 and the second vehicle sound 1 15 by a sound integration module 170. In step 31 5, the feedback sound 15 is communicated to a user 205.

[00038] With reference to FIG. 5, a flow chart of the steps of the method for providing sound feedback to a user or manager of one or more vehicles is disclosed according to another embodiment. In step 295, the first vehicle sound 75 is communicated. In step 300, the second vehicle sound 1 15 is communicated. In step 305, the first vehicle sound 75 and the second vehicle sound 1 15 are received by an electronic data processing system 150. In step 320, the feedback sound 15 is formed or determined from the first vehicle sound 75 and the second vehicle sound 1 15 by determining whether the first vehicle 27 and the second vehicle 37 are operating properly. The feedback sound 15 is a dissonant chord 180 if at least one of the first vehicle 27 and the second vehicle 37 is not operating properly. The feedback sound 15 is a major chord 185 if the first vehicle 27 and the second vehicle 37 are operating properly.

[00039] Referring to FIG. 6, a flow chart of the steps of the method for providing sound feedback to a user or manager of one or more vehicles is disclosed according to yet another embodiment. In step 295, the first vehicle sound 75 is communicated. In step 300, the second vehicle sound 1 15 is communicated. In step 305, the first vehicle sound 75 and the second vehicle sound 1 1 5 are received by an electronic data processing system 150. In step 325, the feedback sound 15 is formed or determined from the first vehicle sound 75 and the second vehicle sound 1 15 by determining whether the first vehicle 27 and the second vehicle 37 are operating properly. The feedback sound 15 is produced in an amplified manner 190 if at least one of the first vehicle 27 and the second vehicle 37 is not operating properly. The feedback sound 15 is produced in a non-amplified manner 195 if the first vehicle 27 and the second vehicle 37 are operating properly.

[00040] Advantageously, the feedback system 10 enables the user 205 to react more quickly to changing conditions by listening for the feedback sound 15. This saves fuel, prevents damage to the first vehicle 27 and the second vehicle 37, and provides other benefits.
