Configuration of Vehicle 1

As illustrated in FIG. 1, the vehicle 1 according to an example embodiment may include an information collector 10, a detector 20, a setting unit 30, an accelerator position detector 40, an audio output unit 50, and a control processor 60.

[e] The information collector 10 collects information regarding a mood of an occupant of the vehicle 1.

In one example, as the information regarding the mood of the occupant, the information collector 10 may collect voices uttered by the occupant, captured images of the occupant, biological information of the occupant, and social media information on posts posted on social media by the occupant.

For example, the information collector 10 may be a device that collects the voices uttered by the occupant using a sensor such as a microphone disposed inside the vehicle 1.

The information collector 10 may be a device that collects images of the face, body, and other parts of the occupant captured by a sensor such as a camera disposed inside the vehicle 1, for example.

The information collector 10 may be a device that collects the biological information, such as a body heat, a heart rate, and a sweat amount, of the occupant using a communication interface that communicates with a wearable device of the occupant, for example.

The information collector 10 may be a device that collects posts or the like posted on a social media website by the occupant using a communication interface that communicates with a portable device (e.g., a smartphone or a tablet) of the occupant, for example.

The information collector 10 may send the collected information regarding the mood of the occupant to the detector 20.

The detector 20 detects a current mood of the occupant based on the information regarding the mood of the occupant.

In one example, the detector 20 may detect a current mood of the occupant based on the information on moods of the occupant received from the information collector 10, and may send the result of detection to the setting unit 30.

An exemplary method of detecting the current mood of the occupant using the detector 20 is described below with reference to FIGS. 2 and 3.

Based on the information regarding the mood of the occupant received from the information collector 10, the detector 20 may determine which mood of good, ordinary, and bad moods the occupant currently has.

As illustrated in FIG. 2, the detector 20 may detect words representing the mood of the occupant from the voices uttered by the occupant, and may detect the current mood of the occupant based on the detected words.

The detector 20 may further detect sounds representing the mood of the occupant, such as laughter, a cry, a whistle, a singing voice, a humming voice, a tutting sound, or a sigh, and may detect the current mood of the occupant based on the result of detection.

The detector 20 may analyze the captured image of the occupant to detect, for example, a facial expression of the occupant (e.g., the degree of lifting of a corner of the mouth), the number of times of blinking, the degree of opening of the eyes, the direction of the line of sight, a restless behavior, and a driving posture of the occupant, and may detect the current mood of the occupant based on the result of detection.

As illustrated in FIG. 3, the detector 20 may detect the current mood of the occupant based on the biological information such as a body heat, a breathing rate, a heart rate, or a blood pressure of the occupant.

The detector 20 may detect words representing the mood of the occupant from, for example, text messages posted on social media by the occupant, and may detect the current mood of the occupant based on the detected words.

The detector 20 may integrate the results of detection of the mood of the occupants based on the respective pieces of information collected by the information collector 10 with each other to determine the mood of the occupant.

In one example, the detector 20 may count the number of items determined to correspond to the good mood and the number of items determined to correspond to the bad mood in the results of determination based on the respective pieces of information received from the information collector 10 descried above. The detector 20 may determine the mood represented by the items larger in number than the other as the current mood of the occupant.

In a case where neither the item determined to correspond to the good mood nor the item determined to correspond to the bad mood is detected by the determination of the mood based on the information received from the information collector 10, the detector 20 may determine that the current mood of the occupant is the ordinary mood.

Note that the detection method described above is a mere example, and each item may be weighted upon the counting described above, for example.

For example, in a case where a negative word is detected from the voices uttered by the occupant, the detector 20 may assign a weight of 5 to the negative word rather than counting the negative word as 1 upon the counting of items.

The detection method described above is not limited to the method described above, and any detection method may be used as long as the detector 20 is able to detect the current mood of the occupant by integrating the respective pieces of information on moods of the occupant collected by the information collector 10.

The setting unit 30 may set a sound quality parameter of a traveling sound to be outputted to the interior of a vehicle compartment of the vehicle 1 based on the mood of the occupant.

The setting of a sound quality parameter of the traveling sound by the setting unit 30 may include at least setting of a tone frequency of the traveling sound, setting of a sound pressure of the traveling sound, and setting of sound followability to accelerator positions.

In one example, the setting unit 30 may set the tone frequency, the sound pressure, and the sound followability to accelerator positions based on the mood of the occupant detected by the detector 20, and may send the setting values to the control processor 60.

The setting of a tone frequency may be the setting of a tone of the traveling sound to be outputted to the interior of the vehicle compartment of the vehicle 1. In one example, such a setting value that reproduces a characteristic traveling sound of a formula car, a high-end sports car, or a high-end large-displacement car may be set in the setting of a tone frequency.

For example, the setting unit 30 may send the control processor 60 a traveling sound frequency characteristic set for each accelerator position angle to reproduce a traveling sound of a formula car.

The setting of a sound pressure may be the setting of a parameter of a sound pressure level of the traveling sound to be outputted to the interior of the vehicle compartment of the vehicle 1. In one example, the setting unit 30 may send the control processor 60 a maximum sound level of the traveling sound to be outputted to the interior of the vehicle compartment of the vehicle 1.

The setting of sound followability to accelerator positions may be the setting of a parameter of an amount of change in traveling sound upon an accelerator operation. In one example, the setting unit 30 may set the amount of change in sound pressure to be made upon a change in the accelerator position and the amount of change in frequency characteristic of the traveling sound to be made upon a change in the accelerator position.

As illustrated in FIG. 4, when the detector 20 determines that the occupant is in the good mood, the setting unit 30 may set a tone frequency of a formula car, a sound pressure of 65 dB, and a mid-level sound followability to accelerator positions (i.e., a sound quality parameter A), for example.

That is, when the detector 20 determines that the occupant is in the good mood, the setting unit 30 may set an energetic and powerful traveling sound of a formula car to keep and improve the good mood of the occupant.

When the detector 20 determines that the occupant is in the ordinary mood, the setting unit 30 may set a tone frequency of a high-end sport car, a sound pressure of 70 dB, and a high-level sound followability to accelerator positions (i.e., a sound quality parameter B), for example.

That is, when the detector 20 determines that the occupant is in the ordinary mood, in order to improve the mood of the occupant to the good mood, the setting unit 30 may set a traveling sound of a high-end sport car with a sound pressure and a tone that greatly change in accordance with the accelerator positions to give the occupant a joyful driving experience.

When the detector 20 determines that the occupant in the bad mood, the setting unit 30 may set a tone frequency of a high-end large-displacement car, a sound pressure of 60 dB, and a low-level sound followability to accelerator positions (i.e., a sound quality parameter C), for example.

That is, when the detector 20 determines that the occupant is in the bad mood, the setting unit may set a traveling sound of a high-end large-displacement car with a low sound pressure that the occupant feels relaxed with, rather than the energetic traveling sound of a formula car or the like.

The accelerator position detector 40 may detect accelerator positions of the vehicle 1.

In one example, the accelerator position detector 40 may include, for example, an accelerator position sensor. The accelerator position sensor may detect a rotation angle of a throttle valve shaft when the driver who drives the vehicle 1 performs an accelerator operation, and the acceleration position detector 40 may send the result of detection to the control processor 60.

The audio output unit 50 may be, for example, a sound speaker. The audio output unit 50 may output a traveling sound generated by the control processor 60 to be described later to the interior of the vehicle compartment of the vehicle 1.

The control processor 60 may control an overall operation of the vehicle 1 in accordance with a control program stored in a non-illustrated read only memory (ROM).

In the present example embodiment, the control processor 60 may generate the traveling sound based on the sound quality parameter and the accelerator position, and may output the traveling sound to the interior of the vehicle compartment of the vehicle 1.

In one example, the control processor 60 may generate a traveling sound based on the sound quality parameter set by the setting unit 30 and the information on the accelerator position received from the accelerator position detector 40, and may send the traveling sound to the audio output unit 50.

Process in Vehicle 1

An exemplary procedure of the process in the vehicle 1 is described below with reference to FIG. 5.

The information collector 10 may acquire the information on moods of the occupant (Step S110), following which the procedure may proceed to Step S120.

The detector 20 may detect the current mood of the occupant received from the information on moods of the occupant received from the information collector 10 (Step S120), following which the procedure may proceed to Step S130.

The setting unit 30 may determine which mood of the good, ordinary, and bad moods the current mood of the occupant detected by the detector 20 corresponds to (Step S130).

If the setting unit 30 determines that the current mood of the occupant detected by the detector 20 corresponds to the good mood (Step S130: GOOD), the procedure may proceed to Step S140.

If the current mood of the occupant detected by the detector 20 corresponds to the ordinary mood (Step S130: ORDINARY), the procedure may proceed to Step S150.

If the detector 20 determines that the current mood of the occupant detected by the detector corresponds to the bad mood (Step S130: BAD), the procedure may proceed to Step S160.

When determining that the current mood of the occupant detected by the detector 20 corresponds to the good mood (Step S130: GOOD), the setting unit 30 may set the setting value of the sound quality parameter A to the control processor 60 (Step S140), following which the procedure may proceed to Step S170.

When determining that the current mood of the occupant detected by the detector 20 corresponds to the ordinary mood (Step S130: ORDINARY), the setting unit 30 may set the setting value of the sound quality parameter B to the control processor 60 (Step S150), following which the procedure may proceed to Step S170.

When determining that the current mood of the occupant detected by the detector 20 corresponds to the bad mood (Step S130: BAD), the setting unit 30 may set the setting value of the sound quality parameter C to the control processor 60 (Step S160), following which the procedure may proceed to Step S170.

The control processor 60 may generate the traveling sound based on the sound quality parameter set by the setting unit 30 and the accelerator position received from the accelerator position detector 40 (Step S170), and may output the traveling sound to the interior of the vehicle compartment of the vehicle 1. Thereafter, the procedure may end.

Workings and Effects

As described above, the setting unit 30 of the vehicle 1 according to the above-described example embodiment sets the sound quality parameter of the traveling sound to be outputted to the interior of the vehicle compartment of the vehicle 1 based on the current mood of the occupant detected by the detector 20.

The control processor 60 generates the traveling sound based on the sound quality parameter set by the setting unit 30 and the accelerator position, and outputs the traveling sound to the interior of the vehicle compartment of the vehicle 1.

That is, the vehicle 1 detects the current mood of the occupant based on the information on moods of the occupant collected by the information collector 10, sets the sound quality parameter (e.g., the sound frequency, the sound pressure, and the sound followability to the accelerator position) matching the current mood of the occupant, and provides the traveling sound to the occupant.

It is therefore possible for the vehicle 1 to provide the traveling sound matching the current mood of the occupant, which makes it possible to improve the mood of the occupant.

When determining that the occupant is in the bad mood, the vehicle 1 may set the traveling sound with a low sound pressure to calm down the current mood of the occupant. The bad mood of the occupant is thereby improved during driving of the vehicle 1.

When determining that the occupant is in the ordinary mood, the vehicle 1 may set the energetic traveling sound that greatly changes in accordance with accelerator positions. This provides the occupant with an exhilarating and joyful driving experience to improve the current mood of the occupant.

When determining that the occupant is in the good mood, the vehicle 1 may set the energetic and powerful traveling sound. This provides the occupant with an exhilarating and joyful driving experience to maintain or improve the good mood of the occupant.

The detector 20 may detect the current mood of the occupant based on the information including the voices uttered by the occupant, the captured images of the occupant, and the biological information of the occupant that are collected by the information collector 10.

That is, the detector 20 may detect the current mood of the occupant based on the content of utterances of the occupant, the facial expressions of the occupant, and the biological information of the occupant on which the mood of the occupant is prominently reflected.

The vehicle 1 is thus able to detect the current mood of the occupant with high accuracy and provide the traveling sound matching the current mood of the occupant.

The detector 20 may detect the current mood of the occupant based on the social media information on the occupant's posts collected by the information collector 10.

That is, the detector 20 may detect the current mood of the occupant based on the social media information that explicitly describing the moods of the occupant.

Accordingly, the vehicle 1 is able to detect the current mood of the occupant with high accuracy and provide the traveling sound matching the current mood of the occupant.

Modification Example 1

A control system including the vehicle 1 and a server communicable with the vehicle 1 may be provided, and the process to be performed by the detector 20 described above may be performed in the server.

The server may be coupled to the vehicle 1 via the internet to mutually communicate with each other.

The server may include circuitry that detects the current mood of the occupant based on the information on moods of the occupant received from the information collector 10. The server may further include a transmitter provided with a communication interface that receives the information on moods of the occupants in the vehicle 1 from the vehicle 1 and sends the result of detection at the circuitry (i.e., a detection result) to the setting unit 30 of the vehicle 1.

Based on the information acquired from the server as a response to the information sent to the server (i.e., the result of detection of the current mood of the occupant detected in the server), the setting unit 30 may set a sound quality parameter of a traveling sound.

The control system is thus able to provide the occupant with the traveling sound matching the current mood of the occupant, which makes it possible to improve the mood of the occupant.

Further, the server may be coupled to multiple vehicles to receive the information on moods of occupants from the respective vehicles. The server may detect the current moods of the occupants based on the received information, and may then send the results of detection to the respective vehicles.

That is, the server may detect the current moods of the occupants based on the information on moods of the occupants received from the respective vehicles, and may send the results of the detection to the respective vehicles.

This eliminates the need for providing each of the vehicles with the detector 20 that detects the mood of the occupant, reducing costs of the vehicle.

Further, the server may secure sufficient resources enough to detect the mood of the occupant, which enables a more detailed detection of the mood of the occupant.

The server is thus able to detect the mood of the occupant with higher accuracy.

Modification Example 2

The vehicle 1 described above detects the mood of the occupant at the start of driving after boarding of the occupant on the vehicle 1, and determines the sound quality parameter of the traveling sound based on the detected mood. However, when a change in the mood of the occupant is detected during traveling of the vehicle 1, the vehicle 1 may reset the sound quality parameter currently set to another sound quality parameter matching the mood of the occupant after the change in the mood.

For example, when detecting a change in the mood of the occupant from the bad mood to the ordinary mood, the detector 20 may send data indicating that the current mood of the occupant is the ordinary mood may be sent to the setting unit 30. The setting unit 30 may then change the sound quality parameter currently set to the sound quality parameter corresponding to the ordinary mood.

That is, the vehicle 1 may continuously detect the mood of the occupant during traveling of the vehicle 1, and may change the traveling sound in accordance with the change in the mood of the occupant. The vehicle 1 is thus able to always provide the traveling sound matching the mood of the occupant during traveling the vehicle 1.

Because the vehicle 1 is able to always provide the traveling sound matching the mood of the occupant, it is possible for the vehicle 1 to further improve the mood of the occupant.

Modification Example 3

The sound quality parameter to be set by the setting unit 30 of the vehicle 1 described above may be changed depending on preferences of the occupant.

For example, when the occupant prefers a slightly lower, more powerful traveling sound or a sound with a higher sound pressure to the traveling sound of a high-end sport car currently outputted to the interior of the vehicle compartment of the vehicle 1, the preference of the occupant may be reflected on the sound quality parameter to be set by the setting unit 30.

The vehicle 1 is thus able to provide the traveling sound matching the preference of the occupant, which makes it possible to further improve the mood of the occupant.

Note that it is possible to implement the vehicle 1 of the example embodiments of the disclosure by recording the processes to be executed by, for example, the detector 20, the setting unit 30, and the control processor 60 on a non-transitory recording medium readable by a computer system, and causing, for example, the detector 20, the setting unit 30, and the control processor 60 to load the programs recorded on the non-transitory recording medium thereon to execute the programs.
