Description

Technical Field

[0001] The present invention belongs to the technical field of prompt sound, and in particular relates to a prompt information adjustment device, a system and a vehicle. Background Art

[0002] With the comprehensive intelligence of automobiles, the in-car information prompt function has also become highly integrated and intelligent. Cars have begun to become intelligent products for human-computer interaction that integrate entertainment, office, life and social interaction. At this stage, human-computer interaction has become diversified, and there has been a shift from drivers to passengers. Car prompt sounds usually refer to voice or sound signals emitted by cars under specific operations to remind drivers or passengers to pay attention to certain situations. For example, at certain times, the car's prompt sounds will include horn sounds, warning sounds, door closing confirmation sounds, etc. The prompt information has also been upgraded from the original single visual and auditory system to multi-dimensional prompts, including vision, hearing, touch, and smell, which can increase the efficiency and accuracy of prompts, and ensure that people inside the vehicle can receive information prompts and make the right choices. However, the current vehicle prompt system has the problem of being too single. Summary of the invention

[0003] In view of this, the present invention aims to provide a prompt information adjustment device, system and vehicle to solve the problem that the vehicle prompt system is too single.

[0004] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0005] A prompt information adjustment device, comprising:

[0006] A prompt sound collection module, used for collecting prompt sounds, and the prompt sound collection module is arranged on the vehicle body;

[0007] A visual detection module, used to detect the driver's eye movement, the visual detection module is arranged on the vehicle body;

[0008] A prompt tone storage module, used for storing different prompt tones;

[0009] The controller has a judgment logic, which judges whether the driver notices the prompt sound through the driver's eye movement signal detected by the visual detection module, and if the driver notices it, the prompt sound remains unchanged. If the driver does not notice it, the prompt sound is switched.

[0010] Furthermore, the prompt sound collection module is arranged on the seat back.

[0011] Furthermore, the prompt sound collection module is a microphone arranged on the seat headrest, and the microphone is hidden and embedded in the seat headrest;

[0012] At least two microphones are provided, one each on both sides of the seat headrest near the human ear.

[0013] Furthermore, the visual detection module includes an eye tracker; the eye tracker is arranged on a dashboard directly in front of the human face.

[0014] Furthermore, the prompt information adjustment device also includes an olfactory prompt module, which is connected to the controller and is used to generate a special smell and non-toxic and harmless smoke for prompting;

[0015] The controller determines whether the driver notices the prompt tone. If the driver notices it, the prompt tone remains unchanged. If the driver does not notice it, the prompt tone is switched and the olfactory prompt module is triggered at the same time.

[0016] When the controller determines that the driver's eye vision area stays within the specified area through the information provided by the visual detection module, the prompt sound is valid and the prompt stops;

[0017] According to the reaction time of adults, the reaction time of adults to auditory stimulation is 140-180ms, and it takes 750ms to make a corresponding reaction. Therefore, if the controller does not detect any visual movement of the driver within 180ms, it is assumed that the driver has not received the prompt sound signal, and the olfactory prompt module is triggered for further prompts;

[0018] If no operation is performed within 1 second after the prompt tone sounds, the intelligent assistance system will intervene and replace the driver to avoid accidents.

[0019] The olfactory cue module includes an odor generator and a smoke generator.

[0020] Furthermore, the olfactory prompt module is arranged at the front air-conditioning outlets and the rear air-conditioning outlets.

[0021] Furthermore, the prompt information adjustment device also includes a ventilation linkage module, which controls the opening of the vehicle windows to achieve automatic ventilation in the vehicle after the olfactory prompt module is started for a set time.

[0022] Further, the prompt information device further comprises a tactile prompt module, the tactile prompt module comprises a seat vibrator, the seat vibrator is arranged in the seat, and provides vertical vibration of the seat;

[0023] The controller determines again whether the driver notices the prompt sound. If the driver notices it, the prompt sound stops and the tactile prompt module stops. If the driver does not notice it, the prompt sound is switched, the tactile prompt module is triggered again, and the intelligent driving module is switched on at the same time for driving assistance.

[0024] Furthermore, the prompt information adjustment device also includes a visual prompt module, and the visual prompt module includes prompt icon adjustment, color change, and size change.

Thus, features defined as "first", "second", and the like may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0042] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0043] like Figures 1 to 9 As shown, a prompt information adjustment device includes:

[0044] A prompt sound collection module, used for collecting prompt sounds, is arranged on the vehicle body;

[0045] A visual detection module, used for detecting the eye movement of the driver, and arranged on the vehicle body;

[0046] A prompt tone storage module, used for storing different prompt tones;

[0047] The controller has a judgment logic, which judges whether the driver notices the prompt sound through the driver's eye movement signal detected by the visual detection module, and if the driver notices it, the prompt sound remains unchanged. If the driver does not notice it, the prompt sound is switched.

[0048] In a preferred embodiment of the present invention, the decibel of the prompt sound after switching is increased, and the logic of increasing the decibel of the prompt sound includes:

[0049] Set the original decibel level to X, and increase it by 0.1X;

[0050] Detect whether the driver notices the prompt sound. If the driver notices the prompt sound, stop switching the prompt sound. If the driver does not notice the prompt sound, continue switching the prompt sound with increased decibels.

[0051] If the original decibel setting of the prompt tone is 40 decibels, the prompt tone is increased by 4 decibels to 44 decibels for the first time; and the prompt tone is continuously detected to see whether the user notices the prompt tone. If the user has not noticed the prompt tone, the prompt tone is switched to be increased by 4 decibels to 48 decibels.

[0052] If the driver notices the prompt sound for the first time, it will switch to an encouraging sound. The encouraging sound can be set as a game passing sound effect to increase fun and interactivity.

[0053] If after three reminders and continuous detection, no prompt tone is heard, a final warning is issued. The final warning prompt tone is stored in advance. The final warning prompt tone can be recorded in advance or a personalized prompt tone, such as a voice recording of a relative, or a prompt tone with a higher frequency;

[0054] In addition, the judgment logic in the controller includes a continuous detection feedback function, which not only switches the prompt tone, but can continuously detect the prompt tone and switch the prompt tone stored in advance. For example, users can preset N reminders in advance according to different habits, not limited to three reminders.

[0055] In this embodiment, according to the hearing characteristics of the human ear, for every 10dB increase in sound pressure level, the loudness heard by the human ear increases by about 1 times. Therefore, on the basis of the original sound pressure level of the prompt sound, another 10dB will be increased, so that the driver will subjectively have a significant increase in loudness, so that he can perceive the prompt sound and respond accordingly.

[0056] In a preferred embodiment of the present invention, the frequency of playing the prompt tone after switching is increased, and the logic of increasing the frequency of playing the prompt tone includes:

[0057] Set the original playback frequency to YHz, and increase it by Y;

[0058] Detect whether the driver notices the prompt sound. If the driver notices the prompt sound, stop switching the prompt sound. If the driver does not notice the prompt sound, continue switching the prompt sound with increased playback frequency.

[0059] For example: If the playback frequency of a certain prompt tone is 1Hz, increase it by 1Hz for the first time, and continue to check whether the prompt tone is heard. If it is not noticed, switch to a 3Hz prompt tone;

[0060] If the driver notices the prompt sound for the first time, it will switch to an encouraging sound, which can be set as a game-clearing sound effect to increase fun and interactivity. The game-clearing sound effect will bring joy and a sense of accomplishment to the driver.

[0061] After three reminders and continuous detection, if no prompt tone is heard, a final warning tone is issued. The final warning tone is stored in advance and can be a pre-recorded or personalized prompt tone, such as a voice recording of a relative; or a prompt tone with a higher playback frequency;

[0062] In addition, the judgment logic in the controller includes a continuous detection feedback function, which not only switches the prompt tone, but can continuously detect the prompt tone and switch the prompt tone stored in advance. For example, users can preset N reminders in advance according to different habits, not limited to three reminders.

[0063] In this embodiment, the frequency of the prompt sound playback can be increased according to the hearing characteristics of the human ear (for example, the playback interval is changed from 500ms to 100ms), thereby creating a subjective feeling of urgency and tension, thereby prompting the driver to perform corresponding operations.

[0064] In a preferred embodiment of the present invention, the prompt sound collection module is arranged on a seat back.

[0065] In a preferred embodiment of the present invention, the prompt sound collection module is a microphone arranged on the seat headrest, and the microphone is hidden and embedded in the seat headrest.

[0066] In a preferred embodiment of the present invention, at least two microphones are provided, one each on both sides of the seat headrest close to the human ear.

[0067] In a preferred embodiment of the present invention, the visual detection module includes an eye tracker.

[0068] In a preferred embodiment of the present invention, the eye tracker is arranged on a dashboard directly in front of the person's face.

[0069] In a preferred embodiment of the present invention, the prompt information adjustment device also includes an olfactory prompt module, which is connected to the controller. The olfactory prompt module can be an odor generator and a smoke generator, which are used to generate special odors and non-toxic and harmless smoke, so that the driver can be reminded. The controller determines whether the driver notices the prompt sound, if noticed, it remains unchanged, if not noticed, the prompt sound is switched, and the olfactory prompt module is triggered at the same time. When the controller determines that the driver's eye visual area stays in the specified area through the information provided by the visual detection module, the prompt sound is valid and the prompt is stopped; in actual use, according to the reaction time of adults, the reaction time of auditory stimulation of adults is about 140-180ms, and the time required to make a corresponding reaction is about 750ms, so it is set that if the controller does not monitor any action of the driver's vision within 180ms, it is considered that the driver has not received the prompt sound signal, and the olfactory prompt module is triggered for further prompts; if no operation is performed within 1s under this prompt sound, the intelligent assistance system intervenes to replace the driver's operation to avoid accidents.

[0070] In a preferred embodiment of the present invention, the olfactory prompt module is arranged at the front air-conditioning outlets and the rear air-conditioning outlets.

[0071] In a preferred implementation manner of the present invention, the information prompting device further includes a tactile prompting module.

[0072] In a preferred embodiment of the present invention, the tactile prompt module comprises a seat vibrator, which is arranged in the seat to provide vertical vibration of the seat.

[0073] In a preferred embodiment of the present invention, the controller again determines whether the driver notices the prompt sound. If the driver notices it, the prompt sound stops; if the driver does not notice it, the prompt sound is switched, the tactile prompt module is triggered again, and the intelligent driving module is switched in at the same time to perform driving assistance.

[0074] In a preferred embodiment of the present invention, the prompt information adjustment device further includes a visual prompt module, and the visual prompt module specifically includes prompt icon adjustment, color change, size change, etc.

[0075] In a preferred embodiment of the present invention, the prompt information adjustment device further includes a ventilation linkage module, which can control the opening of the vehicle windows to achieve automatic ventilation in the vehicle after the olfactory prompt module is started for a set time.

[0076] The present invention also provides a prompt information adjustment system, comprising the prompt information adjustment device.

[0077] The present invention also provides a vehicle, comprising the prompt sound adjustment system.

[0078] The present invention solves the problem that the vehicle prompt system is too single and provides richer prompt methods. The prompt information adjustment device is provided with a prompt sound collection module, a visual detection module, a prompt sound storage module, an olfactory prompt module, a tactile prompt module, a visual prompt module and a controller, so as to facilitate the collection of prompt sounds, detection of the driver's eye movements, storage of different prompt sounds, prompting or touching the driver to pay attention to the prompt sound, icon adjustment, color change, size change and detected driver's eye movement signals and determine whether the driver notices the prompt sound.

[0079] Example 1

[0080] The cause of electric vehicle fire may involve multiple factors. Once the battery catches fire due to various reasons, it will have serious consequences and may eventually affect the safety of people and property. For example, if the vehicle is in a place where the noise outside is too high (120 decibels) or near a factory, relying solely on the in-car prompt sound may not be able to alert the occupants. At this time, the olfactory prompt module also starts to work.

[0081] Once an abnormality is detected in the battery, the first auditory prompt is given, that is, the prompt sound is given inside the car. If the driver cannot perceive the battery alarm through hearing due to excessive external noise, the olfactory prompt module placed near the front air-conditioning outlet will start up, and emit burnt and non-toxic and harmless smoke into the cab through the air-conditioning outlet. When the driver smells the abnormal odor and smoke, he can judge that there is a very dangerous problem with the vehicle and can promptly move away from the vehicle to a safe place and wait for rescue.

[0082] In addition, 5 minutes after the olfactory prompt module is activated, the ventilation linkage module will be automatically activated to control the opening of the windows, realize automatic ventilation in the car, and avoid driver discomfort.

[0083] Example 2

[0084] Visual cues are generally displayed on vehicle instruments. In certain vehicle use scenarios, due to lighting issues, the visual cues are not obvious enough, making them unaware to the driver. The visual detection module fails to detect any operation by the driver. Visual cues such as low tire pressure are moved, changed in color, or changed in size to attract the driver's attention, thereby serving as a prompt.

[0085] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
