Description
FIELD

The present disclosure relates to systems and methods for outputting vehicle tire pressure related audible messages via exterior vehicle speakers or exciters.

DETAILED DESCRIPTION
Overview

The present disclosure describes a vehicle that may facilitate a user to conveniently know the tire pressures of one or more vehicle tires without having to use a pressure gauge. The vehicle may include an external speaker system including a plurality of speakers that may output audible messages indicative of vehicle tire pressures when the user may be in proximity to the vehicle, thus eliminating a need to use a pressure gauge to measure the tire pressure. In some aspects, the vehicle may include four tire pressure measurement systems (TPMSs), with one TPMS associated with each vehicle tire. The vehicle may use inputs obtained from the TPMSs to determine a real-time tire pressure of each vehicle tire and may use the external speaker system to output the real-time tire pressure for user's convenience.


In an exemplary aspect, when the user may be filling tire pressure/air in a vehicle tire, the vehicle may identify a speaker closest to the vehicle tire that may be getting filled and cause the identified speaker to output a real-time tire pressure. As an example, the speaker may output “36 psi,” “38 psi,” “40 psi,” as the user inflates the vehicle tire. In this case, the user may regularly hear the audible messages and may not be required to use pressure gauge or view pressure readings on external displays to know about the real-time tire pressure. In some aspects, the vehicle may further cause the speaker to output an alert notification when the tire pressure increases greater than an upper tire pressure threshold, thereby preventing the user from over-inflating the vehicle tire. The vehicle may follow a similar (and opposite) process when the user may be deflating the vehicle tire.


In another exemplary aspect, when the user may be located in proximity to the vehicle or approaching the vehicle and tire pressure of one or more vehicle tires may be low (e.g., less than a predefined pressure threshold), the vehicle may cause all the exterior speakers to output an audible message including an identifier of the vehicle tire(s) that may have low pressure. For example, the speakers may output a message stating, “Front left tire has low pressure”. Responsive to hearing such a message, the user may take remedial actions before driving the vehicle.


In yet another exemplary aspect, when the user may be located in proximity to the vehicle and inspecting the vehicle (e.g., by moving around the vehicle), the vehicle may determine a real-time user location based on inputs obtained from a vehicle's sensor suite. The vehicle may further determine a vehicle tire and a speaker closest to the real-time user location. The vehicle may cause the determined speaker to output an audible message including a tire pressure of the determined vehicle tire, thereby enabling the user to conveniently know about the tire pressure without using a pressure gauge. In some aspects, as the user moves around the vehicle, the vehicle may cause the exterior speakers to one-by-one output tire pressure of each vehicle tire, thereby facilitating the user in the vehicle inspection process.


The vehicle may be further configured to control the volume of the audible messages output from the speakers, such that the messages may be clearly audible to the user, but may not disturb other users who may be in the same area where the vehicle may be located. Further, the vehicle may ensure that the audible message volume is greater than an ambient noise level, so that the user may conveniently hear the messages.


The present disclosure discloses a vehicle that outputs audible messages indicative of vehicle tire pressures, thereby eliminating the need to use pressure gauges. Further, the vehicle outputs audible messages including real-time tire pressure when the user may be filling air in a vehicle tire, thereby reducing a probability of tire over-inflation. Furthermore, the vehicle outputs audible messages when the tire pressure in one or more vehicle tires may be low, thereby enabling the user to perform timely remedial actions.


These and other advantages of the present disclosure are provided in detail herein.


Illustrative Embodiments

The disclosure will be described more fully hereinafter with reference to the accompanying drawings, in which example embodiments of the disclosure are shown, and not intended to be limiting.



FIG. 1 depicts an example environment 100 in which techniques and structures for providing the systems and methods disclosed herein may be implemented. The environment 100 may include a vehicle 102. The vehicle 102 may take the form of any passenger or commercial vehicle such as, for example, a car, a work vehicle, a crossover vehicle, a van, a minivan, etc. Further, the vehicle 102 may be a manually driven vehicle and/or may be configured to operate in a fully autonomous (e.g., driverless) mode or a partially autonomous mode and may include any powertrain such as, for example, a gasoline engine, one or more electrically-actuated motor(s), a hybrid system, etc.


The environment 100 may further include a user 104 who may be located in proximity to the vehicle 102. In the exemplary aspect depicted in FIG. 1, the user 104 is shown as filling-in tire pressure/air in a vehicle tire 106; however, the present disclosure is not limited to such an aspect. In other aspects (not shown), the user 104 may be approaching the vehicle 102, opening a vehicle door, inspecting the vehicle 102 by moving around a vehicle periphery, and/or performing any other operation in proximity to the vehicle 102.


The vehicle 102 may be configured to output audible messages related to vehicle tire pressure when the user 104 may be located in proximity to the vehicle 102 (and/or performing one or more operations described above). In one exemplary aspect, the audible messages may enable the user 104 to conveniently know about the real-time vehicle tire pressure when the user 104 may be filling air in the tire 106, thus considerably reducing a possibility of tire over-inflation or under-inflation. In another exemplary aspect, the audible messages may enable the user 104 to get timely alerts when a vehicle tire may be having low tire pressure (e.g., less than a predefined pressure threshold) and when the user 104 may be approaching the vehicle 102 and/or opening a vehicle door. In this case, the user 104 may get the corresponding vehicle tire checked and/or fill-in air in the vehicle tire, before driving the vehicle 102. In yet exemplary aspect, the audible messages may enable the user 104 to know about the tire pressure of each vehicle tire when the user 104 may be moving around and inspecting the vehicle 102. These exemplary aspects are described in detail in the description later below.


In some aspects, the vehicle 102 may include a detection unit (shown as detection unit 240 in FIG. 2) that may be configured to detect a user presence and a user location in proximity to the vehicle 102. Specifically, the detection unit may include a sensor suite (shown as sensor suite 244 in FIG. 2) that may localize the user location and/or a location of a user device associated with the user 104, when the user 104 may be located in proximity to the vehicle 102 (e.g., within a predefined distance of the vehicle periphery). In an exemplary aspect, the sensor suite may include, but is not limited to, a vehicle camera, a radio detection and ranging (radar) sensor, a light detection and ranging (lidar) sensor, an ultra-wideband (UWB) sensor, a Bluetooth low energy (BLE) sensor, and/or the like.


The detection unit may further include one or more tire pressure monitoring systems (or “TPMSs”, shown as TPMSs 246 in FIG. 2) configured to detect a tire pressure of each vehicle tire. In an exemplary aspect, the detection unit may include four TPMSs, with one TPMS disposed in proximity to each vehicle tire. The vehicle 102 may further include an exterior speaker system that may include a plurality of speakers (or panel exciters). For example, the exterior speaker system may include a front left speaker disposed in proximity to a front left vehicle tire, a front right speaker disposed in proximity to a front right vehicle tire, a rear left speaker disposed in proximity to a rear left vehicle tire, and a rear right speaker disposed in proximity to a rear right vehicle tire. The vehicle 102 may be configured to control exterior speaker system operation based on inputs obtained from the detection unit and cause one or more speakers to output the audible messages indicative of vehicle tire pressure, as described below.


In a first exemplary aspect, when the vehicle 102 determines that the user 104 may be filling-in tire pressure in the tire 106 based on the inputs obtained from the detection unit, the vehicle 102 may determine a speaker (from the exterior speaker system) closest to the tire 106 that may be getting inflated and then cause the speaker to output an audible message including a real-time tire pressure. For example, the speaker may output “36 psi” (as shown by a caption 108 of FIG. 1) when the real-time tire pressure associated with the tire 106 may be 36 psi. As and when the real-time tire pressure increases (or decreases) by a predefined amount (e.g., 2 psi, as the user 104 fills the tire pressure), the speaker may output the corresponding real-time tire pressure, e.g., “38 psi”, “40 psi”, etc.


In some aspects, the vehicle 102 may further determine an optimal volume at which the speaker may output the audible message. When the user 104 may be filling in tire pressure in the tire 106, the optimal volume may be such that it is low enough that it does not cause inconvenience to other users who may be located in proximity to the vehicle 102 (and away from the tire 106), but may be higher than an ambient noise level (e.g., higher than the noise emanating from the compressor used to inflate the tire 106).


In a second exemplary aspect, when the vehicle 102 determines (based on the inputs obtained from the detection unit) that the user 104 may be approaching the vehicle 102 or located in proximity to the vehicle 102 and a tire pressure of one or more vehicle tires may be less than a predefined threshold, the vehicle 102 may cause all the speakers of the exterior speaker system to output an audible message including an identifier of the vehicle tire(s) having the less tire pressure. For example, in this case, the speakers may output, “Front left tire has low tire pressure”. In this case, the speakers may output the message at a volume higher than the ambient noise level, so that the user 104 may conveniently hear the audible message and take remedial actions before driving the vehicle 102.


In a third exemplary aspect, when the vehicle 102 determines (based on the inputs obtained from the detection unit) that the user 104 may be moving around the vehicle periphery and inspecting the vehicle 102, the vehicle 102 may track the user's movement and identify a speaker and a vehicle tire closest to the user's real-time location as the user 104 moves. Responsive to identifying the speaker and the vehicle tire, the vehicle 102 may cause the speaker to output a tire pressure of the vehicle tire as the user 104 moves or is located in proximity to the vehicle tire. As an example, the front left speaker may output a tire pressure of the front left vehicle tire when the user 104 may be located in proximity to the front left vehicle tire, the front right speaker may output a tire pressure of the front right vehicle tire when the user 104 may be located in proximity to the front right vehicle tire and so on. In this manner, the user 104 may audibly hear the tire pressure of each vehicle tire as the user 104 moves around the vehicle 102 and may not require pressure gauges to measure tire pressures while inspecting the vehicle 102.


Further vehicle details are described below in conjunction with FIG. 2.


The vehicle 102 implements and/or performs operations, as described here in the present disclosure, in accordance with the owner manual and safety guidelines. In addition, any action taken by the user 104 based on recommendations or notifications provided by the vehicle 102 should comply with all the rules specific to the location and operation of the vehicle 102 (e.g., Federal, state, country, city, etc.). The recommendation or notifications, as provided by the vehicle 102, should be treated as suggestions and only followed according to any rules specific to the location and operation of the vehicle 102.

The TCU 226 may be configured and/or programmed to provide vehicle connectivity to wireless computing systems onboard and off board the vehicle 102 and may include a Navigation (NAV) receiver 234 for receiving and processing a GPS signal, a BLE® Module (BLEM) 236, a Wi-Fi transceiver, an ultra-wideband (UWB) transceiver, and/or other wireless transceivers (not shown in FIG. 2) that may be configurable for wireless communication (including cellular communication) between the vehicle 202 and other systems (e.g., a vehicle key fob, not shown in FIG. 2, the user device 204, etc.), computers, and modules. The TCU 226 may be disposed in communication with the ECUs 214 by way of a bus.

The computing system architecture of the automotive computer 208, the VCU 210, and/or the unit 212 may omit certain computing modules. It should be readily understood that the computing environment depicted in FIG. 2 is an example of a possible implementation according to the present disclosure, and thus, it should not be considered as limiting or exclusive.


The vehicle 102 may further include a detection unit 240 and an exterior speaker system 242. The detection unit 240 may include a sensor suite 244 and one or more TPMSs 246. In some aspects, the sensor suite 244 may be part of the vehicle sensory system 232 and/or the TCU 226. In other aspects, the sensor suite 244 may be a separate unit, as shown in FIG. 2. The sensor suite 244 may be configured to detect a user presence and a user location in proximity to the vehicle 202. In an exemplary aspect, the sensor suite 244 may include a plurality of sensors including, but not limited to, one or more vehicle cameras, radar sensors, lidar sensors, UWB sensors, BLE sensors, radio access technology responders, and/or the like. In some aspects, the sensor suite 244 may detect the user presence and the user location in proximity to the vehicle 202 based on images, inputs, etc. captured by the vehicle cameras, radar sensors, lidar sensors, and/or the like. In other aspects, the sensor suite 244 may detect the user presence and the user location in proximity to the vehicle 202 by determining the presence of the user device 204 (that the user 104 may be carrying) in proximity to the vehicle 202 and localizing/determining the user device location by using, e.g., the UWB sensors, the BLE sensors, the radio access technology responders, and/or the like.


In some aspects, the vehicle 202 may include four TPMSs 246, with one TPMS being disposed in proximity to each vehicle tire. The TPMSs 246 may be configured to continuously (or at a predefined frequency) detect a tire pressure of each vehicle tire.


The exterior speaker system 242 may include a plurality of external speakers configured to output audio signals. For example, as shown in FIG. 3, the exterior speaker system 242 may include a front left speaker 242a, a front right speaker 242b, a rear left speaker 242c, and/or a rear right speaker 242d. In an exemplary aspect, the front left speaker 242a may be disposed in proximity to a front left vehicle tire 106a, the front right speaker 242b may be disposed in proximity to a front right vehicle tire 106b, the rear left speaker 242c may be disposed in proximity to a rear left vehicle tire 106c, and/or the rear right speaker 242d may be disposed in proximity to a rear right vehicle tire 106d.


In accordance with some aspects, the unit 212 may be integrated with and/or executed as part of the ECUs 214. The unit 212, regardless of whether it is integrated with the automotive computer 208 or the ECUs 214, or whether it operates as an independent computing system in the vehicle 102, may include a transceiver 248, a processor 250, and a computer-readable memory 252.


The transceiver 248 may be configured to receive information/inputs from one or more external devices or systems, e.g., the user device 204, one or more connected servers, and/or the like, via the network 206. Further, the transceiver 248 may transmit notifications, requests, signals, etc. to the external devices or systems. In addition, the transceiver 248 may be configured to receive information/inputs from vehicle components such as the detection unit 240, the vehicle sensory system 232, one or more ECUs 214, and/or the like. Further, the transceiver 248 may transmit signals (e.g., command signals) or notifications to the vehicle components such as the BCM 220, the HMI 238, the exterior speaker system 242, and/or the like.


The processor 250 and the memory 252 may be same as or similar to the processor 216 and the memory 218, respectively. In some aspects, the processor 250 may utilize the memory 252 to store programs in code and/or to store data for performing aspects in accordance with the disclosure. The memory 252 may be a non-transitory computer-readable storage medium or memory storing the audible message management program code. In some aspects, the memory 252 may additionally store a three-dimensional (3D) map or geometry associated with the vehicle 202, including location coordinates of one or more vehicle components, vehicle dimensions, and/or the like.


In operation, the processor 250 may obtain inputs from the detection unit 240 continuously or at a predefined frequency. Specifically, the processor 250 may obtain inputs from the sensor suite 244 and each TPMS 246 continuously or at a predefined frequency. Responsive to obtaining the inputs from the detection unit 240, the processor 250 may determine if a predefined condition, from a plurality of predefined conditions, may be met based on the obtained inputs. In an exemplary aspect, the plurality of predefined conditions may include, but is not limited to, a rate of change of tire pressure associated with at least one vehicle tire being greater than a predefined rate threshold (as determined via the inputs obtained from the TPMSs 246), a tire pressure associated with at least one vehicle tire being less than a predefined tire pressure threshold (as determined via the inputs obtained from the TPMSs 246) and a user presence being detected in proximity to the vehicle 202 (as determined via the inputs obtained from the sensor suite 244), a user presence being detected in proximity to the vehicle 202 and a rate of change of user location being greater than a predefined location threshold (as determined via the inputs obtained from the sensor suite 244), and/or the like.


Responsive to determining that a predefined condition, from the plurality of predefined conditions, may be met based on the obtained inputs, the processor 250 may determine a type of the predefined condition that may be met based on the inputs obtained from the detection unit 240. In some aspects, the processor 250 may determine that a first type of predefined condition may be met when the rate of change of tire pressure associated with at least one vehicle tire (from the four vehicle tires 106a-d) may be greater than the predefined rate threshold. As an example, when the user 104 may be filling-in tire pressure in the front left vehicle tire 106a, the rate of change of tire pressure associated with the front left vehicle tire 106a may be greater than the predefined rate threshold (e.g., in range of 0.4 to 0.8 psi per second). In such an instance, the processor 250 may determine that the first type of predefined condition may be met. In some aspects, the predefined rate threshold may be tunable and may increase or decrease after the processor 250 determines that the first type of predefined condition may be met for at least one vehicle tire.


In further aspects, the processor 250 may determine that a second type of predefined condition may be met when a tire pressure associated with at least one vehicle tire may be less than a predefined tire pressure threshold and the user presence may be detected in proximity to the vehicle 202. As an example, when the user 104 may be approaching the vehicle 202 and/or opening a vehicle door, and the processor 250 determines that one or more vehicle tires (from the four vehicle tires 106a-d) may have low tire pressure (i.e., less than the predefined tire pressure threshold), the processor 250 may determine that the second type of predefined condition may be met.


In yet another aspect, the processor 250 may determine that a third type of predefined condition may be met when the user presence may be detected in proximity to the vehicle 202 and the rate of change of user location may be greater than the predefined location threshold. As an example, when the user 104 may be moving around the vehicle periphery and inspecting the vehicle 202, the processor 250 may determine that the third type of predefined condition may be met.


The example predefined conditions described above should not be construed as limiting, and the processor 250 may determine other types of predefined conditions without departing from the present disclosure scope.


Responsive to determining the type of predefined condition that may be met, the processor 250 may identify one or more speakers, from the plurality of speakers associated with the external speaker system 242, to output an audible message based on the type of predefined condition that may be met. The processor 250 may then cause the identified speaker(s) to output an audible message indicative of a tire pressure associated with one or more vehicle tires (from the vehicle tires 106a-d), as described below.


In a first exemplary aspect, when the processor 250 determines that the first type of predefined condition may be met (e.g., when the user 104 may be filling tire pressure in the front left vehicle tire 106a), the processor 250 may identify a speaker, from the speakers 242a-d, that may be closest to the front left vehicle tire 106a. For example, in this case, the processor 250 may identify that the front left speaker 242a may be closest to the front left vehicle tire 106a. Responsive to identifying that the front left speaker 242a may be closest to the front left vehicle tire 106a, the processor 250 may determine a real-time time pressure of the front left vehicle tire 106a (based on the inputs obtained from the associated TPMS 246) and cause the front left speaker 242a to output an audible message including the real-time time pressure. For example, the audible message may output “36 psi” (as shown in FIG. 1). Further, as and when the real-time time pressure increases by a predefined increment amount (e.g., by 2 psi), the processor 250 may cause the front left speaker 242a to output another audible message including the real-time time pressure (e.g., “38 psi,” “40 psi,” and so on).


In some aspects, the processor 250 may further determine an optimal volume associated with the first type of predefined condition at which the front left speaker 242a may output the audible message and then cause the front left speaker 242a to output the audible message at the optimal volume. As an example, when the processor 250 determines that the first type of predefined condition may be met, the processor 250 may determine the optimal volume such that only the user 104 located in proximity to the front left speaker 242a may hear the audible message, and other users who may be located in the same area as the vehicle 202 are not disturbed. Stated another way, in this case, the optimal volume may be less than a predefined volume threshold so that the audible message may have a low volume.


In some aspects, the detection unit 240 may further include a microphone (not shown) that may be configured to capture an ambient noise in proximity to the vehicle 202. The processor 250 may obtain the inputs from the microphone and determine an ambient noise level based on the obtained inputs. The processor 250 may further determine the optimal volume to output the audible message such that the volume may be greater than the ambient noise level. As an example, when the user 104 may be filling tire pressure in the front left vehicle tire 106a, the processor 250 may determine the optimal volume such that it may be greater than the sound being emitted from the compressor providing the pressure to the front left vehicle tire 106a. This may enable the user 104 to conveniently hear the audible message including the real-time vehicle tire pressure.


In further aspects, the processor 250 may determine that the real-time vehicle tire pressure associated with the front left vehicle tire 106a may be greater than a predefined upper tire pressure threshold (e.g., when the user 104 may be filling tire pressure in the front left vehicle tire 106a). Responsive to such determination, the processor 250 may cause the front left speaker 242a to output an alert notification, thereby preventing the user 104 from over-inflating the front left vehicle tire 106a.


A similar (and opposite) process may be followed when the user 104 may be reducing or deflating tire pressure in one or more vehicle tires. In this case, the processor 250 may cause the front left speaker 242a/external speaker system 242 to output audible messages as the tire pressure decreases from a higher value to a lower value.


Furthermore, the processor 250 may disable the front left speaker 242a to output any further audible message, when the processor 250 determines that the rate of change of tire pressure associated with the front left vehicle tire 106a may have decreased below a predefined low rate threshold.


In a second exemplary aspect, when the processor 250 determines that the second type of predefined condition may be met (e.g., when the tire pressure associated with at least one vehicle tire may be less than the predefined tire pressure threshold and the user presence may be detected in proximity to the vehicle 202), the processor 250 may determine an identifier of the vehicle tire that may have its tire pressure less than predefined tire pressure threshold. For example, when the front left vehicle tire 106a may have its tire pressure less than the predefined tire pressure threshold, the processor 250 may determine the identifier as “front left vehicle tire”. Responsive to identifying the tire identifier, the processor 250 may cause all the speakers associated with the external speaker system 242 to output an audible message including the tire identifier. For example, in this case, the processor 250 may cause the front left speaker 242a, the front right speaker 242b, the rear left speaker 242c, and/or the rear right speaker 242d to output an audible message stating, e.g., “the front left vehicle tire has low tire pressure”. Responsive to hearing such a message, the user 104 may take remedial actions before driving the vehicle 202. In this case, the audible message may be output from the speakers, as described above, to ensure that the user 104 clearly hears the message and takes timely remedial actions.


In this case as well, the processor 250 may determine the ambient noise level based on the inputs obtained from the microphone/detection unit 240 and then determine an optimal volume to output the audible message based on the ambient noise level. Specifically, in this case, the processor 250 may cause the front left speaker 242a, the front right speaker 242b, the rear left speaker 242c, and/or the rear right speaker 242d to output the audible message at a volume that may be greater than the ambient noise level (thereby facilitating the user 104 to conveniently hear the audible message).


In a third exemplary aspect, when the processor 250 determines that the third type of predefined condition may be met (e.g., when the user presence may be detected in proximity to the vehicle 202 and the rate of change of user location may be greater than the predefined location threshold), the processor 250 may determine a real-time user location in proximity to the vehicle 202 based on the inputs obtained from the sensor suite 244. Responsive to determining the real-time user location, the processor 250 may determine a “zone” in proximity to the vehicle 202 where the user 104 may be located, based on the real-time user location and the 3D map or geometry associated with the vehicle 202 (that may be stored in the memory 252). For example, the processor 250 may determine whether the user 104 may be located in zone “Z1”, “Z2”, “Z3” or “Z4” (as shown in FIG. 3) based on the real-time user location and the 3D vehicle map or geometry.


Responsive to determining the real-time user location or the zone as described above, the processor 250 may determine a vehicle tire closest to the real-time user location or in the zone. For example, when the user 104 may be located in the zone “Z1”, the processor 250 may determine that the front left vehicle tire 106a may be closest to the real-time user location. Responsive to determining that the front left vehicle tire 106a may be closest to the real-time user location, the processor 250 may determine a tire pressure associated with the front left vehicle tire 106a based on the inputs obtained from the associated TPMS 246. The processor 250 may further determine a speaker (e.g., the front left speaker 242a) that may be closest to the front left vehicle tire 106a or in the zone “Z1”. The processor 250 may further cause the front left speaker 242a to output an audible message including the tire pressure associated with the front left vehicle tire 106a. For example, the front left speaker 242a may output an audible message stating, “The front left vehicle tire has a pressure of 36 psi”.


As and when the user 104 moves around the vehicle 202 (thereby changing the “zones” in which the user 104 may be located), the processor 250 may cause the speakers 242a-d to one-by-one output the tire pressures of the vehicle tires that may closest to the real-time user location. In this manner, during vehicle inspection, the user 104 may conveniently know about the tire pressure of each vehicle tire, without having to use a pressure gauge.


In some aspects, if the user 104 may be standing/located in between two zones, the processor 250 may either cause the external speaker system 242 not to output any tire pressure, or may cause the external speaker system 242 to output tire pressures for vehicle tires associated with both the zones in which the user 104 may be standing.


In further aspects, if the user 104 may be moving back and forth between two or more zones, the processor 250 may cause the speaker of that zone to output the audible message where the user 104 spends the most time duration or a time duration above a predefined time duration threshold. Furthermore, if multiple zones have multiple users present or there are spurious locations due to non-human objects or obstructions, then the processor 250 may cause the speaker to output only the pressure of the most reliably detected zone.


Although the description above describes an aspect where the external speaker system 242 outputs audible messages indicative of tire pressures, in additional aspects, one or more visual indicators (e.g., light-based indicators) may also be used to indicate tire pressures. Furthermore, in some aspects, audio prompts and chimes may be used to indicate tire pressures.
