TITLE OF INVENTION
Audio Alert System and Method for a Vehicle

APPLICANT
TVS MOTOR COMPANY LIMITED, an Indian company, having its address at “Chaitanya”, No.12 Khader Nawaz Khan Road, Nungambakkam, Chennai 600 006.

PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the invention and the manner in which it is to be performed.

FIELD OF THE INVENTION
[001] The present invention relates to a system and a method for providing alerts in a vehicle and more particularly, to a system and a method for providing audio alerts to a user of the vehicle.
BACKGROUND OF THE INVENTION
[002] There are vehicle alert systems and solutions in the known art to communicate, with a user / rider of the vehicle during riding, about the status or change in status of the riding conditions and general condition of the vehicle.
[003] Currently any alert or warning about vehicle conditions is displayed on a speedometer or with an LED indication on the speedometer. Such display is not in the general viewing sight of the rider and the rider has to consciously make an effort to keep checking the speedometer and is prone to getting distracted while navigating the vehicle. Further, usage of other display units or gadgets during ride will also result in distraction. Hence the usage of warning alerts at the speedometer leads to distracted riding, which is undesirable and may prove dangerous.
[004] Further, the alert system for rider regarding audio warning indication might not be effective to the rider while riding in a certain riding condition. Rider may not be able to listen to the alert. Even if the audio alerts are provided in place of visual indication or in addition to the same, at higher speed / acceleration, the rider might not be able to listen to the audio alerts due to the ambience noise.
[005] Further, the alert system should be able to communicate the alert to the user irrespective of the actual riding condition and environmental factors. Irrespective of external factors, the rider should be able to receive / listen and be able to comprehend the alert clearly so as to act upon the same as required.
[006] It is known in the art to provide alert systems using an external device or in-vehicle device in a closed environment. These alert systems, however, cannot perform / operate based on current riding conditions and environment factors.
[007] In another known prior art, a system is provided wherein, a speed-dependent control signal is derived from the output signal of a vehicle tachometer generator and between the low-frequency output of the playback device and the associated speakers, a damping control circuit is provided. The known device has the disadvantage that the volume increase, which acts automatically as a function of the driving speed, in contrast to the manual usually aurally correct volume setting, results in a change in the sound impression which has a disruptive effect on the human ear. This correction in volume setting is connected with the speed of the vehicle irrespective of the ambient noise. The sound based on correction as a function of speed may be too loud or too low for the user depending upon the ambient conditions.
[008] Thus, there is a need in the art for an audio alert system and method for vehicles, which address at least the aforementioned problems.

DETAILED DESCRIPTION OF THE INVENTION
[030] The present invention relates to audio alert systems and methods for a vehicle. More particularly, the present invention relates to such audio alert systems and methods for a two-wheeler vehicle.
[031] Figure 1 illustrates a system 100 for alerting a user (192) of a vehicle (190) with at least one audio alert, in accordance with an embodiment of the invention. In various embodiments, the vehicle (190) is a saddle type vehicle, a two-wheeler vehicle such as a scooter or a motorcycle, a three-wheeler vehicle, or any such open vehicle where the user (192) of the vehicle (190) is in direct contact with the ambient conditions and the speed and other ambient noise factor affect the performance of an audio alert system such as the system (100). The system (100) comprises a vehicle control unit (110) mounted on the vehicle (190) and in communication with an electronic control unit (ECU) (194) and a plurality of sensors (196) of the vehicle (190); and a wearable device (120) being worn by the user (192) in communication with the vehicle (190).
[032] In an embodiment, the wearable device (120) is in communication with the vehicle (190) using a wireless communication module (112). The wireless communication module (112) may be a Bluetooth and other wireless protocols.
[033] The user (192) may be a rider, a pillion rider, a passenger and the like of the vehicle (190). A second control unit (122) is disposed in the wearable device (120). The vehicle control unit (110) is configured to receive vehicle parameters from at least one of the ECUs (194) and the sensors (196) of the vehicle (190). The vehicle control unit (110) is configured to generate the at least one audio alert based on the received vehicle parameters and transmit the generated at least one audio alert and corresponding alert characteristics to the second control unit (122) based on a priority level of the generated at least one audio alert. In various embodiments, the corresponding alert characteristics comprise at least one of identifiers of a data-file to be played as the at least one audio alert, a volume level, a voice tone, and a repetition frequency of the generated at least one audio alert.
[034] In various embodiments, the vehicle parameters include at least one of a vehicle speed, a vehicle acceleration, and a lean angle of the vehicle (190), a throttle position, a surrounding obstacle, and the like.
[035] The alert characteristics further include volume level, voice (male/female), frequency (how often it is to be played) of the generated at least one audio alert. Examples of the data-file to be played include: “speed is high”, “sudden change in speed”, and the like. Such audio alert data-file played in the wearable device (120) enable the user (192) to take appropriate actions without being getting distracted from the effort of looking at the alerts on places out his sight such as the speedometer. In an embodiment, alert characteristics further include a combination of intermittent pulses or warbling sounds along with an alert being read out and may form part of the audio alert.
[036] The second control unit (122) is communicatively connected to the vehicle control unit (110) and is configured to: receive the generated at least one audio alert and the corresponding alert characteristics from the vehicle control unit (110) and alert the user (192) with the generated at least one audio alert based on the corresponding alert characteristics and ambient conditions of the vehicle (190).
[037] In an embodiment, the vehicle control unit (110) is configured to determine an audio volume level of the at least one audio alert based on at least one of the vehicle parameters. The audio volume level is part of the corresponding alert characteristics of the generated at least one audio alert.
[038] In an embodiment, the second control unit (122) is configured to adjust the audio volume level of the received at least one audio alert for playing in the wearable device (120). That is, the second control unit (122) adjusts the volume of the audio alert playing in speakers of the wearable device (120) such as the helmet by taking control of the volume control of the wearable device (120) automatically.
[039] In an embodiment, the ambient conditions comprise an ambient noise level of the vehicle (190) including a noise level of the ambient wind around the vehicle (190). The wearable device (120) comprises a sensing device (124) for sensing the ambient noise level of the vehicle (190). The second control unit (122) is configured to control the audio volume level of the at least one audio alert based on the ambient noise level.
[040] In an embodiment, the wearable device (120) is a helmet of the user (192) having speakers and the sensing device (124) is mounted on the helmet.
[041] Wind noise by air turbulence when the vehicle is riding at about at 35mph is >40db. The wind noise is measured by the sensing device (124) mounted on the wearable device (120) / helmet.
[042] In an embodiment, the sensing device (124) has a noise cancellation module (126) configured to reduce the ambient noise level.
[043] In an embodiment, the wearable device (120) comprises a noise cancellation module (126) configured to reduce the ambient noise level and determine the audio volume level of the at least one audio alert for playing in the wearable device (120).
[044] In an embodiment, the second control unit (122) is configured to: adjust the audio volume level of the at least one audio alert for playing in the wearable device (120) based upon the determined audio volume level of the at least one audio alert; and provide feedback to the vehicle control unit (110) based upon the adjustment in the audio volume level of the at least one audio alert. That is, the second control unit (122) informs that the audio volume level has been altered for the alert to a new value based on the determined ambient noise level.
[045] Average noise level on an open road is about 85-95db when the vehicle is riding at about 35mph, and it increases to 110-116db for 65mph. Further, average audio listening range of a human is 75-136db at ideal conditions. The second control unit (122) calculates an optimum audio volume level of the at least one audio alert based on the noise level on the road. In an embodiment, the second control unit 122 may have prestored audio volume levels mapped to different ambient noise levels.
[046] In an embodiment, the priority level of the at least one audio alert is classified as a high priority level, a medium priority level, and a low priority level. The audio alert may be about a warning such as blind spot detection, forward collision alert, ABS controlling alert and the like. High priority of alert is defined by the severity of impact of these warnings. Warnings that require immediate attention are classified as high priority. For example, high priority alerts demand the following:
• Immediate braking for evasion of crash
• Immediate steering maneuver for evasion of crash
• Immediate termination of initiated action
[047] Similarly, medium priority alerts may be the detection of low battery level/ fuel levels, detection of an obstacle far away from the vehicle (190), and the like. Further, low priority alerts may be failure of turn indicators of the vehicle (190), detection of low priority obstacles such as minor obstructions on the road, etc. In an embodiment, the priority level of the alerts is also decided by the vehicle control unit (110) based on the vehicle parameters such the speed of the vehicle (190), distance of the vehicle (190) from the obstacle, etc.
[048] In an embodiment, the vehicle control unit (110) performs prioritization of alerts and based on the prioritization decides the sequence of audio alerts to be played and varies the alert characteristics such as frequency and volume level, language of alert, accordingly. For a high priority alert, the vehicle control unit (110) may set a higher volume. In an embodiment, combinations of the alert characteristics for different audio alerts may be configured in the memory of the vehicle control unit.
[049] In an embodiment, the vehicle control unit (110) is further configured to generate a visual alert corresponding to the at least one audio alert to be displayed on at least one of: a cluster of the vehicle (190) and an auxiliary device. In an embodiment, the user (192) of the vehicle (190) may configure some of the alert characteristics such as a voice tone (male/female) based on their choice in the auxiliary device, such as a smart phone, a personal digital assistant or any wearable device such as smart headphones and the like in possession of the user (192). The auxiliary device may be communicably coupled to the vehicle (190). In an embodiment, the vehicle control unit (110) generates the audio alert on comparing the different vehicle parameters with their corresponding thresholds to generate the audio alerts. The vehicle control unit (110) may be performing these comparisons at a predetermined frequency as configured by the OEM (Original Equipment Manufacturer) of the vehicle (190) or the user (192) of the vehicle (190).

The vehicle (190) includes a vehicle control unit (110) mounted on the vehicle (190). The vehicle control unit (110) is in communication with an electronic control unit (ECU) (194) and a plurality of sensors (196) of the vehicle (190). The user (192) wears a wearable device (120) having a second control unit (122) communicatively connected to the vehicle control unit (110). The method (200) comprises: receiving (202) at the vehicle control unit (110), vehicle parameters from at least one of the ECU (194) and the sensors (196) of the vehicle (190); generating (204), by the vehicle control unit (110), the at least one audio alert based on the received vehicle parameters; transmitting (206), by the vehicle control unit (110), the generated at least one audio alert and corresponding alert characteristics to the second control unit (122) based on a priority level of the generated at least one audio alert; receiving (208), at the second control unit (122), the generated at least one audio alert and the corresponding alert characteristics from the vehicle control unit (110); and alerting (210), by the second control unit (122), the user (192) with the generated at least one audio alert based on the corresponding alert characteristics and the ambient conditions of the vehicle (190).
[051] Figures 3A-C illustrates the method (200A) for alerting the user (192) of the vehicle (190) with at least one audio alert, in accordance with another embodiment of the invention. In an embodiment, the method (200) for alerting the user (192) comprises determining (212), by the vehicle control unit (110), an audio volume level of the at least one audio alert based on at least one of the vehicle parameters. The audio volume level is part of the corresponding alert characteristics of the generated at least one audio alert.
[052] In an embodiment, the method (200) for alerting the user (192) comprises adjusting (214), by the second control unit (122), the audio volume level of the received at least one audio alert for playing in the wearable device (120).
[053] In an embodiment, the method (200) for alerting the user (192) comprises: sensing (216), by a sensing device (124) of the wearable device (120), an ambient noise level of the vehicle; and controlling (218), by the second control unit (122), the audio volume level of the at least one audio alert based on the ambient noise level.
[054] In an embodiment, the method (200) for alerting the user (192) comprises: reducing (220), by the sensing device (124), the ambient noise level; and determining (222), by second control unit (122), the audio volume level of the at least one audio alert for playing in the wearable device (120).
[055] In an embodiment, the method (200) for alerting the user (192) comprises: reducing (224), by a noise cancellation module (126) of the wearable device (120), the ambient noise level; and determining (226), by the noise cancellation module (126), the audio volume level of the at least one audio alert for playing in the wearable device (120).
[056] In an embodiment, the method (200) for alerting the user (192) comprises: adjusting (228), by the second control unit (122), the audio volume level of the at least one audio alert for playing in the wearable device (120) based upon the determined audio volume level of the at least one audio alert; and providing (230), by the second control unit (122), a feedback based upon adjustment in the audio volume level to the vehicle control unit (110).
[057] In an embodiment, the method (200) for alerting the user (192) comprises: generating (232), by the vehicle control unit (110), a visual alert corresponding to the at least one audio alert; and displaying (234), by the vehicle control unit (110), the visual alert on at least one of: a cluster of the vehicle (190) and an auxiliary device.
[058] In an embodiment, the method (200) for alerting the user (192) comprises: generating, by the vehicle control unit (110), a vibration/haptic feedback alert corresponding to the at least one audio alert; and communicating, by the vehicle control unit (110), the vibration/haptic feedback to the rider (192), who may be differently abled of the vehicle (190).
[059] In an embodiment, the audio alert is played in one of the left or right earpieces of the wearable device (120) based on the side on which detection of a blind spot is done by a RADAR system connected to the vehicle (190).
[060] For example, if a blind spot is detected by the RADAR system connected to the vehicle (190), The vehicle control unit (110) checks for the priority level of the warning and determines whether it is a high priority alert and requires an audio alert to be generated, The vehicle control unit (110) in communication with the ECUs (194) and the sensors (196) receives the current vehicle speed and determines an audio volume level for the audio alert, the repetition frequency, the tone, and the like for the audio alert. The vehicle control unit (110) further transmits the audio alert and the audio alert characteristics to the wearable device (120) such as the helmet. At the Helmet, the audio alert is received by the second control unit (122) and the sensing device (124) measures the ambient noise level. The second control unit (122) based on the noise level determined by the sensing device (124), sets the audio volume level of the audio alert to a predefined decibel and plays the audio file received from the vehicle control unit (110) at that adjusted audio volume level. Further, the second control unit (122) sends a feedback to the vehicle control unit (110) on the adjustment of the volume of the alert as a safety requirement.
[061] Advantageously, the system and the method provided by the invention provides an audio alert regarding vehicle status and riding conditions taking in to account the ambient noise conditions so that the same is communicated to the user of the vehicle without him getting distracted or having to make special conscious efforts.
[062] The invention also avoids interface with a user device / mobile in the middle of the ride as the vehicle directly interacts wirelessly with a wearable device such as a helmet. Not only does the invention not require an additional device but also encourages wearing of the helmet by the rider to receive alerts. The side on which the alert is played and the volume of the alert is controlled based upon the blind spot direction and ambient conditions enabling greater user experience.
[063] Since the audio alert is played in the wearable device such as the helmet, the rider need not make any conscious effort to check the speedometer or other externa device continually to remain informed. This avoids rider distraction at conditions where rider’s concentration and maneuverability are required and cannot be compromised.
[064] While the present invention has been described with respect to certain embodiments, it will be apparent to those skilled in the art that various changes and modification may be made without departing from the scope of the invention as defined in the following claims.
