Description

  The present invention relates to a simulated running sound generation device and a simulated running sound generation system.

  Conventionally, an electric vehicle (EV) and a hybrid electric vehicle (HEV) using an electric motor (motor) as a travel drive source are known. Since EVs and HEVs (hereinafter referred to as electric vehicles) have low noise, it is difficult for a pedestrian or the like who passes around an electric vehicle that is traveling or stopped to predict the possibility of the electric vehicle approaching or starting in advance. . On the other hand, it has been studied to make a pedestrian or the like aware of the possibility of the approach or start of the electric vehicle by outputting a pseudo driving sound (hereinafter, pseudo driving sound) from the electric vehicle.

  However, it is not preferable to always output the pseudo running sound from the viewpoint of noise and battery consumption. Therefore, a technique for outputting a simulated running sound according to the situation has been proposed. For example, in the “Pedestrian Friendly” AlertSystem, which is being developed by GM (registered trademark), a pedestrian or the like with warning sound and passing when a pedestrian or the like is detected using a sensor mounted on an electric vehicle. A technology to call attention to the above has been proposed. Further, Patent Document 1 proposes a technique for outputting a pseudo running sound only when it is determined that a host vehicle is present on a general road with a lot of traffic by referring to map information and the host vehicle position.

JP 2005-253236 A

  However, in the “Pedestrian Friendly” Alert System, since a pedestrian or the like is detected by a sensor of the own vehicle, if a pedestrian or the like exists in the blind spot of this sensor, the pedestrian or the like cannot be detected. Therefore, even when a pedestrian or the like is present around the host vehicle, a warning sound is not output, and there is a problem that the pedestrian or the like cannot be alerted.

  Further, in the technique of Patent Document 1, in a situation where the positioning accuracy of the own vehicle position is poor or an actual road shape is changed and an error occurs in the map information, an output of simulated running sound in accordance with the actual situation is output. The problem that it is not possible to perform is caused.

  The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide a simulated running sound generation device and a simulated program that can more surely output a simulated running sound in accordance with an actual situation. The object is to provide a running sound generation system.

  According to the simulated running sound generation system of the first aspect, the simulated running sound transmitted when the information transmitting device existing outside the electric vehicle and the simulated running sound generating device mounted on the electric vehicle can communicate with each other. The simulated running sound is output according to the output control information related to the output control. Therefore, it is not influenced by things such as the blind spot of the vehicle sensor for detecting the pedestrian and the light vehicle driver (hereinafter referred to as the dangerous object), the blind spot of the camera for imaging the dangerous object, the positioning accuracy of the own vehicle position, and the accuracy of the map information. It is possible to output a simulated running sound when there is a risk target around the host vehicle or when there is a high possibility that it exists.

  For example, if the information transmission device is a portable terminal carried by a person, the output transmitted from the portable terminal even if the person carrying the portable terminal is present in the blind spot around the vehicle A pseudo running sound can be output according to the control information. In addition, when the information transmission device is a roadside machine, by installing the roadside machine in a place with a lot of traffic, even if there is a danger target in the blind spot around the vehicle near the roadside machine, A simulated running sound can be output according to the output control information transmitted from the roadside machine.

  As a result, according to the above configuration, it is possible to more surely output the simulated running sound according to the actual situation.

  According to the second aspect of the present invention, since the schedule for outputting the simulated traveling sound is created based on the information on the output time of the simulated traveling sound respectively transmitted from the plurality of information transmission devices, the plurality of information It becomes possible to output the simulated traveling sound in order according to the output time of the simulated traveling sound requested by each of the transmission devices.

  According to the configuration of claim 3, when the output times of the simulated running sound requested by each of the plurality of information transmission devices overlap, the simulated running order is given priority in favor of the output time of the pseudo running sound having a high priority. Sound can be output. Therefore, it is possible to give priority to the output of the simulated running sound directed to a target that requires more simulated running sound, such as a child or a visually impaired person.

  According to the fourth aspect of the present invention, the direction and volume for outputting the simulated running sound are determined based on the current position information transmitted from the portable terminal carried by the person, so the portable terminal is carried. It is possible to output a simulated running sound toward the direction in which the person exists, or to output a simulated running sound at a volume corresponding to the distance to the person carrying the mobile terminal. Therefore, it becomes possible to make alerting more effectively.

  Further, according to the configuration of the fifth aspect, since the volume for outputting the simulated running sound is determined based on the volume information of the simulated running sound, the simulation is performed in accordance with the volume of the simulated running sound requested by the information transmission device. A running sound can be output. Therefore, for example, when the simulated running sound is output for an object such as an elderly person that requires a greater simulated running sound, or when the simulated running sound is output for a place where the noise is loud, It is possible to make the alerting more effective by increasing.

  According to the configuration of claim 6, when the dangerous object around the roadside machine is detected by the roadside machine, the output control information generated based on the detection result of the dangerous object is transferred from the roadside machine to the simulated running sound generator. Since it becomes possible to transmit, even if there is a danger target in the aforementioned blind spot around the host vehicle in the vicinity of the roadside machine, it is possible to alert the user by outputting a simulated running sound.

  According to the configuration of claim 7, the output control information transmitted from the mobile terminal is received by the roadside device, and the received output control information is transmitted from the roadside device to the simulated running sound generator. Therefore, even if the mobile terminal you are carrying is outside the range where you can communicate with the simulated running sound generator, it will also output simulated running sound even for people who prefer to be alerted by outputting simulated running sound It becomes possible to call attention.

  According to the configuration of claim 8, the output control information transmitted from the mobile terminal is received by the vehicle-mounted device, and the received output control information is transmitted from the vehicle-mounted device to the simulated running sound generator. Therefore, even if the mobile terminal you are carrying is outside the range where you can communicate with the simulated running sound generator, it will also output simulated running sound even for people who prefer to be alerted by outputting simulated running sound It becomes possible to call attention.

  According to the configuration of claim 9, when a dangerous object around the vehicle on which the vehicle-mounted device is mounted is detected by the vehicle-mounted device, the output control information generated based on the detection result of the dangerous object is transmitted from the vehicle-mounted device. Since it can be transmitted to the simulated running sound generation device, there is a danger target in the blind spot in the vicinity of the own vehicle (that is, the electric vehicle equipped with the simulated running sound generation device) in the vicinity of the vehicle equipped with the vehicle-mounted device. Even if it exists, it is possible to alert by outputting a simulated running sound.

  Further, according to the simulated running sound generation system of claim 10, when the on-vehicle device detects a dangerous object around the vehicle on which the on-vehicle device is mounted, the output control information generated based on the detection result of the dangerous object is obtained. Since it can be transmitted from the vehicle-mounted device to the simulated running sound generation device, the blind spot in the vicinity of the own vehicle (that is, the electric vehicle equipped with the simulated running sound generation device) in the vicinity of the vehicle on which the on-vehicle device is mounted is used. Even if there is a danger target, it is possible to alert the user by outputting a simulated running sound.

  According to the simulated running sound generation device of the eleventh aspect, the simulated running sound is output according to the output control information related to the control of the simulated running sound output transmitted from the information transmission device existing outside the electric vehicle. Become. Therefore, it is not influenced by things such as the blind spot of the vehicle sensor for detecting the pedestrian and the light vehicle driver (hereinafter referred to as dangerous object), the blind spot of the camera for imaging the dangerous object, the positioning accuracy of the own vehicle position and the accuracy of the map information It is possible to output a simulated running sound when there is a risk target around the host vehicle or when there is a high possibility that it exists. As a result, according to the above configuration, it is possible to more surely output the simulated running sound according to the actual situation.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a schematic configuration of a simulated running sound generation system 100 to which the present invention is applied. As shown in FIG. 1, the simulated traveling sound generation system 100 includes a simulated traveling sound generation device 1, a mobile terminal 2, and a roadside device 3.

  The simulated running sound generator 1 is mounted on an electric vehicle such as an electric vehicle (EV) or a hybrid electric vehicle (HEV) that uses an electric motor (motor) as a running drive source (driving force source). In the present embodiment, as illustrated in FIG. 1, the description will be continued assuming that the simulated traveling sound generator 1 is mounted on each of the electric vehicle A and the electric vehicle B, for example.

  The portable terminal 2 is a terminal that is carried by a person such as a pedestrian or a light vehicle driver. Note that the mobile terminal 2 may be configured to use a mobile phone, a PDA (Personal Digital Assistants), or the like. The roadside machine 3 is fixed and installed at a predetermined place such as the roadside. In this embodiment, the roadside machine 3 shall be installed in a place with high possibility of traffic such as a school road or a supermarket parking lot. In addition, the portable terminal 2 and the roadside machine 3 are equivalent to the information transmitter of a claim.

  Further, in the simulated running sound generating system 100, the simulated running sound generating device 1 is a simulated running mounted outside the electric vehicle on which the simulated running sound generating device 1 is mounted, specifically, on a vehicle other than the electric vehicle. Communication with the sound generator 1, the portable terminal 2, and the roadside device 3 is possible. In the simulated running sound generation system 100, in particular, communication between the simulated running sound generating device 1 and the mobile terminal 2, communication between the simulated running sound generating device 1 and the roadside device 3, the mobile terminal 2 and the roadside device. For communication with the wireless communication device 3, wireless communication with a relatively short communication distance is used. Note that the communicable distance in these wireless communications may be, for example, about several meters to several tens of meters. Moreover, what is necessary is just to set it as the structure which uses DSRC (Dedicated Short Range Communication) which is narrow area communication as these radio | wireless communications, for example.

  Here, a schematic configuration of the mobile terminal 2 will be described with reference to FIG. FIG. 2 is a block diagram illustrating a schematic configuration of the mobile terminal 2. As shown in FIG. 2, the mobile terminal 2 includes a communication unit 21, a position detector 22, a storage device 23, and a control device 24.

  The communication unit 21 communicates with the simulated running sound generator 1 and the roadside machine 3. Further, when the simulated running sound output request information is sent from the control device 24, the communication unit 21 transmits the simulated running sound output request information to the simulated running sound generation device 1 in accordance with an instruction from the control device 24. . The simulated running sound output request information is information related to the control of the simulated running sound output of the electric vehicle by the simulated running sound generation device 1. Therefore, the pseudo running sound output request information corresponds to the output control information in the claims.

  The position detector 22 is a positioning device that sequentially detects the current position of the mobile terminal 2, and sends information on the detected current position to the storage device 23. Therefore, the position detector 22 corresponds to a position detection unit in claims. The position detector 22 is a sensor of the portable terminal 2 by a sensor such as a GPS receiver for GPS (Global Positioning System) that detects the current position of the vehicle based on radio waves from a geomagnetic sensor, a gyroscope, and an artificial satellite. The current position may be detected.

  The storage device 23 stores (stores) each piece of information constituting the simulated running sound output request information. Therefore, the storage device 23 corresponds to an output control information storage unit. For example, the storage device 23 stores an identification ID of the mobile terminal 2 as identification information for individually identifying devices. Note that the terminal ID of the mobile terminal 2 may be used as the identification ID of the mobile terminal 2. Further, the storage device 23 stores priority information that is information on the priority of the output of the simulated traveling sound in the simulated traveling sound generation device 1 according to the simulated traveling sound output request information from the mobile terminal 2. .

  Here, the priority will be described with reference to FIG. FIG. 3 is a diagram for explaining an example of priority. As shown in FIG. 3, the priority is set for each section of the person carrying the mobile terminal 2 and also for the roadside device 3. Specifically, the largest value “05” is set for the mobile terminal 2 held by the visually impaired. Further, the next largest value “04” is set for the mobile terminal 2 held by the child. Further, an intermediate value “03” is set for the portable terminal 2 mounted on the bicycle (that is, the portable terminal 2 carried by the light vehicle driver). In addition, a value “04” smaller than the intermediate value is set for the mobile terminal 2 held by a general pedestrian. For the roadside device 3, the smallest value “01” is set.

  The priority information is used to prioritize a request having a large priority value when the output timings of the simulated running sound requested by the simulated running sound output request information of each of the plurality of devices overlap. Therefore, for example, as in the example shown in FIG. 3, the priority value for the mobile terminal 2 held by a child or visually impaired person is higher than the mobile terminal 2 or roadside machine 3 held by a general pedestrian. By setting the information, it is possible to give priority to the output of the simulated running sound for a target such as a child or a visually impaired person who needs the simulated running sound more.

  In addition, the storage device 23 stores sound volume information for specifying the sound quality of the simulated running sound and sound quality information for specifying the sound quality of the sound source of the simulated running sound. Further, the storage device 23 stores output time information that is information of an output time for specifying how long the pseudo running sound is to be output. In addition, as output time, it is good also as a structure by which the period of about several seconds-several minutes is set, for example.

  Further, the storage device 23 stores position information that is information on the current position detected by the position detector 22. The position information may be updated every time the current position is newly detected by the position detector 22.

  The control device 24 is configured as a normal computer, and includes a well-known CPU, ROM, RAM, I / O, and a bus line (all not shown) for connecting these configurations. The control device 24 executes various processes based on various information input from the position detector 22 and the storage device 23.

  For example, the control device 24 combines each information such as the identification ID, priority information, volume information, sound quality information, output time information, and position information stored in the storage device 23 into one set (see FIG. 4). A set of information is encoded and sent to the communication unit 21. Note that FIG. 4 is a diagram schematically showing pseudo running sound output request information including a set of groups. Also, the information ID in FIG. 4 is an ID indicating the type of information, and “information ID: 01” indicates pseudo running sound output request information consisting of one set.

  Then, the control device 24 transmits the simulated traveling sound output request information “01” from the communication unit 21 to the simulated traveling sound generating device 1 and the roadside device 3. Therefore, the communication unit 21 corresponds to an output control information transmission unit in claims. Note that the pseudo running sound output request information from the communication unit 21 is transmitted, for example, periodically (for example, every 3 seconds).

  In addition, although identification ID, priority information, volume information, sound quality information, output time information, and position information are shown as the pseudo running sound output request information, the present invention is not necessarily limited thereto. For example, only a part of the identification ID, priority information, volume information, sound quality information, output time information, and position information may be used as the pseudo running sound output request information. In addition, when the mobile terminal 2 is not provided with the position detector 22, the position information may not be used.

  Further, if there is information that is considered to be useful for controlling the simulated running sound, the information may be used as the simulated running sound output request information. For example, the pitch information of the simulated running sound may be used as the simulated running sound output request information. According to this, it becomes possible for the simulated traveling sound generator 1 to output the simulated traveling sound according to the pitch of the simulated traveling sound requested by the mobile terminal 2. Therefore, for example, when the simulated running sound is output to an object such as an elderly person where it is difficult to hear the sound of a specific frequency, the simulated running sound is output at a frequency that is easy to listen to, or the simulated running sound is In the case of outputting, it is possible to make the alerting more effective by outputting at a frequency that is easy to hear even in a noisy place.

  Further, the portable terminal 2 may include an operation input unit (not shown), and the user may be able to set priority information, volume information, sound quality information, output time information, and the like by input to the operation input unit. According to this, it becomes possible to receive the simulated running sound output from the simulated running sound generating device 1 with the volume, sound quality, output time, etc. according to the user's request, and the convenience is improved. In addition, since the priority information can be set on the user side, the same portable terminal 2 can be shared and used by persons with different classifications, thereby improving convenience and versatility. To do.

  Then, the schematic structure of the roadside machine 3 is demonstrated using FIG. FIG. 5 is a block diagram showing a schematic configuration of the roadside machine 3. As shown in FIG. 5, the roadside machine 3 includes a communication unit 31, a dangerous object detection device 32, a storage device 33, and a control device 34.

  The communication unit 31 communicates with the simulated running sound generator 1 and the mobile terminal 2. For example, when the simulated running sound output request information is transmitted from the mobile terminal 2, the communication unit 31 receives this and sends it to the control device 34. Therefore, the communication part 31 is equivalent to the roadside machine side receiving part of a claim. Further, when the simulated running sound output request information is sent from the control device 34, the communication unit 31 transmits the simulated running sound output request information to the simulated running sound generating device 1 in accordance with an instruction from the control device 34. .

  The dangerous object detection device 32 is a device that sequentially detects dangerous objects such as pedestrians and light vehicle drivers existing around the roadside machine 3. Then, the dangerous object detection device 32 sends the detection result of the dangerous object to the control device 34. Therefore, the danger object detection device 32 corresponds to the roadside machine side danger object detection unit in the claims.

  For example, the dangerous object detection device 32 may be configured to use a device that detects a dangerous object by well-known image recognition based on an image captured by a camera (not shown) that captures the periphery of a roadside machine. In addition, as the dangerous object detection device 32, an apparatus that detects an dangerous object by an obstacle sensor such as an ultrasonic sensor or an infrared sensor may be used.

  The storage device 33 stores (stores) pseudo running sound output request information. Further, the storage device 33 may be configured to store, for example, an identification ID, priority information, volume information, sound quality information, and output time information. The identification ID, priority information, volume information, sound quality information, and output time information are the same as described above. In addition, the output time information stored in the storage device 33 is configured to be set so as to continue to be output until the simulated running sound stop request information described later having the same identification ID is received by the simulated running sound generating device 1, for example. Also good. Note that the numerical value of the priority of the priority information stored in the storage device 33 of the roadside device 3 is “01” when the example of FIG. 3 is followed.

  The control device 34 is configured as a normal computer, and includes a well-known CPU, ROM, RAM, I / O, and a bus line (all not shown) for connecting these configurations. The control device 34 executes various processes based on various information input from the communication unit 31, the dangerous object detection device 32, and the storage device 33.

  For example, the control device 34 collects each information such as the identification ID, priority information, volume information, sound quality information, and output time stored in the storage device 33 into one set, and encodes the one set of information. To the communication unit 31. In this case, the type of the simulated running sound output request information is “information ID: 01”. Then, the control device 34 transmits the simulated running sound output request information “01” from the communication unit 31 to the simulated running sound generating device 1. In this case, the simulated traveling sound output request information from the communication unit 31 may be transmitted periodically (for example, every 3 seconds).

  In addition, when the simulated traveling sound output request information is sent from the mobile terminal 2 received by the communication unit 31, the control device 34 decodes the simulated traveling sound output request information. Then, the set of simulated running sound output request information stored in the storage device 33 and the set of simulated running sound output request information derived from the mobile terminal 2 are collected (see FIG. 6), encoded, etc. send. FIG. 6 is a diagram schematically showing pseudo running sound output request information including two sets. Further, “Information ID: 02” in FIG. 6 indicates pseudo running sound output request information including a plurality of sets. Then, the control device 34 transmits the simulated running sound output request information “02” from the communication unit 31 to the simulated running sound generating device 1.

  The simulated running sound output request information “02” including the set of simulated traveling sound output request information derived from the mobile terminal 2 is transmitted only while communication is established between the roadside device 3 and the portable terminal 2. The configuration may be made. According to this, only when there is a danger target carrying the mobile terminal 2 in the vicinity of the roadside device 3, the simulated traveling sound generator 1 can output the simulated traveling sound.

  Further, in the present embodiment, the configuration is shown in which the simulated traveling sound output request information including two sets is transmitted from the roadside device 3 to the simulated traveling sound generating device 1, but the present invention is not necessarily limited thereto. For example, it is good also as a structure which transmits the simulated driving | running | working sound output request information which consists of 2 or more sets to the simulated driving | running | working sound generation apparatus 1 from the roadside machine 3.

  Further, when the detection result of the dangerous object is sent from the dangerous object detection device 32, the control device 34 generates the pseudo running sound output request information based on the detection result. Therefore, the control apparatus 34 is equivalent to the roadside machine side output control information generation part of a claim. As an example, for volume information, sound quality information, and output time, the volume information, sound quality information, and output time stored in the storage device 33 are used, and for the identification ID and priority information, a risk target is used in advance. The prepared identification ID and priority information may be used. Note that the volume information, the sound quality information, and the output time may be configured to use the volume information, the sound quality information, and the output time that are prepared in advance for the dangerous object. In addition, when the dangerous object detection device 32 can also detect the position of the dangerous object, the detected dangerous object position may be used as position information.

  In addition, the control device 34 collects the set of the simulated running sound output request information stored in the storage device 33 and the generated set of the simulated running sound output request information, performs encoding or the like, and sends the encoded information to the communication unit 31. In this case, the type of the simulated running sound output request information is “information ID: 02”. Then, the control device 34 transmits the simulated running sound output request information “02” from the communication unit 31 to the simulated running sound generating device 1. In this case, the simulated running sound output request information from the communication unit 31 may be transmitted periodically (for example, every 3 seconds).

  In addition, when the pseudo traveling sound output request information from the mobile terminal 2 is received by the communication unit 31, the set of pseudo traveling sound output request information derived from the mobile terminal 2 is further summarized and the pseudo traveling sound is output from the communication unit 31. It is good also as a structure which transmits to the sound generator 1. FIG.

  Further, the control device 34 may generate pseudo running sound stop request information and cause the pseudo running sound stop request information to be transmitted from the communication unit 31 to the pseudo running sound generation device 1. Specifically, the control device 34 uses the identification ID stored in the storage device 33 as pseudo running sound stop request information (see FIG. 7), encodes the pseudo running sound stop request information, and sends it to the communication unit 31. . This pseudo running sound stop request information is transmitted when the roadside device 3 requests the pseudo running sound output device 1 to stop the pseudo running sound output. FIG. 7 is a diagram schematically showing the pseudo running sound stop request information. Also, the information ID in FIG. 7 is an ID indicating the type of information, and “information ID: 03” indicates pseudo running sound stop request information. Then, the control device 34 causes the pseudo running sound generation device 1 to transmit the pseudo running sound stop request information “03” from the communication unit 31.

  In this configuration, the roadside machine 3 is installed at the entrance and exit of the parking lot, and the simulated running sound is continuously output from the simulated running sound generator 1 until the electric vehicle enters and exits the parking lot. It is effective when Further, in this case, output time information that is set so as to continue to be output until the simulated traveling sound generation device 1 receives the simulated traveling sound stop request information having the same identification ID from the roadside device 3 installed at the entrance is included. The simulated traveling sound output request information may be transmitted, and the simulated traveling sound stop request information may be transmitted from the roadside device 3 installed at the exit. According to this, after the electric vehicle receives the simulated running sound output request information from the roadside machine 3 installed at the entrance of the parking lot, the simulated running sound stop request information from the roadside machine 3 installed at the exit of the parking lot. Until the simulated running sound generator 1 continues to output the simulated running sound.

  Next, a schematic configuration of the simulated running sound generator 1 will be described with reference to FIG. FIG. 8 is a block diagram showing a schematic configuration of the simulated running sound generator 1. As shown in FIG. 8, the simulated running sound generator 1 includes a communication unit 11, a danger target detection device 12, a storage device 13, a position detector 14, a control device 15, a signal generator 16, a signal amplification unit 17, and a speaker. 18 is provided. In addition, the pseudo | simulation driving | running | working sound generator 1 is equivalent to not only the quasi-running sound generator of a claim but an onboard equipment.

  The communication part 11 communicates with the pseudo | simulation traveling sound generator 1 mounted in the portable terminal 2, the roadside machine 3, and another vehicle. Therefore, the communication part 11 is equivalent to the generator side communication part of a claim. In addition, the communication part 11 is corresponded also to the vehicle equipment side communication part of a claim. In addition, the communication unit 11 receives the simulated traveling sound output request information transmitted from the simulated traveling sound generation device 1 mounted on the mobile terminal 2, the roadside device 3, or another vehicle, and sends it to the control device 15. Therefore, the communication part 11 is also corresponded to the onboard equipment side receiving part of a claim. Further, when the simulated running sound output request information is sent from the control device 15, the communication unit 11 performs the simulated running sound output request information mounted on the other vehicle according to an instruction from the control device 15. It transmits to the sound generator 1.

  The dangerous object detection device 12 is an apparatus that detects a dangerous object such as a pedestrian or a light vehicle driver existing around the host vehicle. Then, the dangerous object detection device 12 sends the detection result of the dangerous object to the control device 15. Therefore, the danger object detection device 12 corresponds to the vehicle-mounted device-side danger object detection unit in the claims.

  For example, the dangerous object detection device 12 may be configured to use a device that detects a dangerous object by well-known image recognition based on an image captured by a camera (not shown) that captures the periphery of the host vehicle. In addition, it is good also as a structure using the apparatus which detects a danger target with obstacle sensors, such as an ultrasonic sensor and an infrared sensor.

  The storage device 13 stores information used when generating the simulated traveling sound output request information based on the information on the sound source of the simulated traveling sound and the detection result of the dangerous target in the dangerous target detection device 12.

  The position detector 14 is a positioning device that sequentially detects the current position of the electric vehicle on which the simulated running sound generator 1 is mounted, and sends information on the detected current position to the control device 15. The position detector 14 includes a geomagnetic sensor, a gyroscope, a wheel speed sensor, and a sensor such as a GPS receiver for GPS (Global Positioning System) that detects the current position of the vehicle based on radio waves from an artificial satellite. What is necessary is just to set it as the structure which detects the present position of the electric vehicle carrying the simulated driving | running | working sound generator 1. FIG.

  The signal generator 16 generates a pseudo running sound according to a schedule to be described later based on control by the control device 15. In addition, the signal amplifying unit 17 amplifies the simulated running sound generated by the signal generator 16 to the volume required by the schedule. Then, the speaker 18 outputs the simulated running sound amplified by the signal amplifying unit 17 to a necessary volume toward the outside of the electric vehicle. Therefore, the speaker 18 corresponds to a simulated running sound output unit.

  Note that a plurality of speakers 18 may be provided. When the direction in which the simulated running sound is output can be specified, the speaker 18 having a strong directivity is used, and the direction of the speaker 18 is driven by driving a motor or the like according to the control from the control device 15. You can change it.

  Further, the simulated running sound generator 1 outputs a simulated running sound corresponding to the vehicle operating states of starting / running, stopping, and acceleration / deceleration during running using a well-known technique. do it.

  The control device 15 is configured as a normal computer, and includes a well-known CPU, ROM, RAM, I / O, and a bus line (all not shown) for connecting these configurations. The control device 15 executes various processes based on various information input from the communication unit 11, the dangerous object detection device 12, the storage device 13, and the position detector 14.

  For example, when the simulated running sound output request information from the mobile terminal 2 received by the communication unit 11 is sent, the control device 15 decodes the simulated running sound output request information. And the control apparatus 15 produces the schedule which outputs the pseudo | simulation running sound according to the position which position information shows with the designated volume and sound quality for the output time designated by this simulated running sound output request information. Further, each time the receiving unit 11 receives the simulated traveling sound output request information, the control device 15 adds or deletes the simulated traveling sound output schedule based on the newly received simulated traveling sound output request information. And update the schedule from time to time. Therefore, the control device 15 corresponds to an output control unit in claims.

  For example, when the output time specified in the simulated running sound output request information transmitted from the mobile terminal 2 is “5 seconds”, the simulated running sound generating device 1 outputs the same simulated running sound for 5 seconds. Create a schedule to If the simulated running sound output request information is continuously transmitted from the portable terminal 2, the communication between the simulated running sound generating device 1 and the portable terminal 2 is established according to this schedule. The same simulated running sound continues to be output until 5 seconds after the problem is resolved. That is, while the electric vehicle travels around the person carrying the portable terminal 2, the pseudo traveling sound is continuously output.

  Further, when the volume information is included in the simulated running sound output request information, a schedule is created so as to output the simulated running sound having the volume indicated by the volume information. Further, when the sound quality information is included in the simulated running sound output request information, a schedule is created so that the simulated running sound is output using the sound source indicated by the sound quality information, for example.

  Further, when the position information is included in the simulated running sound output request information, the control device 15 uses the current position information of the host vehicle detected by the position detector 14 and the position information to control the host vehicle. And a person carrying the portable terminal 2, a distance between the dangerous object detected by the dangerous object detection devices 12 and 32 (hereinafter referred to as a target distance), a person carrying the portable terminal 2 viewed from the own vehicle, The direction of the dangerous object (hereinafter referred to as the target direction) detected by the dangerous object detection devices 12 and 32 is calculated. For example, a schedule may be created to output a simulated running sound with a volume larger than the volume specified by the volume information as the target distance is farther than a certain distance, or a simulated running sound may be output toward the target direction. Create a schedule.

  In addition, when there is an overlap in output time between the multiple sets of simulated running sound output request information, priority is given to the simulated running sound output schedule for the set of simulated running sound output request information with a higher priority value. Create a schedule.

  Further, when the simulated traveling sound generation device 1 directly receives the simulated traveling sound output request information transmitted from the mobile terminal 2, and through the simulated traveling sound generating device 1 mounted on the roadside device 3 or other vehicle. In some cases, the output time overlaps between sets of simulated traveling sound output request information derived from the same portable terminal 2. In this case, on the basis of the identification ID, the control device 15 determines whether or not the pseudo traveling sound output request information is derived from the same portable terminal 2, and one set (for example, the one received later in time) is determined. The configuration may be excluded from the schedule.

  In addition, when the pseudo traveling sound stop request information received from the roadside device 3 received by the communication unit 11 is transmitted, the control device 15 decodes the pseudo traveling sound stop request information. Then, the control device 15 searches the created schedule based on the identification ID included in the pseudo running sound stop request information, the identification ID is the same, and the output time is “the same identification ID. The schedule for outputting the simulated running sound that is “until the reception of the simulated running sound stop termination request information” is deleted from the schedule.

  Here, with reference to FIG. 9, processing related to schedule creation in the control device 15 at the time of information reception in the communication unit 11 of the simulated traveling sound generation device 1 will be described. FIG. 9 is a flowchart showing a flow of processing relating to schedule creation in the control device 15 when information is received by the communication unit 11 of the simulated running sound generating device 1. This flow is started at any time when the communication unit 11 receives the pseudo running sound output request information or the pseudo running sound stop request information.

  First, in step S1, the pseudo running sound output request information and the pseudo running sound stop request information sent from the communication unit 11 are decoded, and the process proceeds to step S2. In step S2, a scheduling process is performed, and the process proceeds to step S3. In the scheduling process, when the information sent from the communication unit 11 is the pseudo running sound output request information, the addition of the simulated driving sound output schedule is added based on the newly received pseudo running sound output request information. To create a schedule. In addition, when the information sent from the communication unit 11 is the pseudo running sound stop request information, the pseudo running sound is output only when the schedule for outputting the pseudo running sound that meets the above-described conditions exists in the schedule. Delete the output schedule of. In addition, when all the schedules for outputting the simulated running sound are lost, the schedule is also lost.

  In step S3, when the schedule exists (Yes in step S3), the process proceeds to step S4. If the schedule does not exist (No in step S3), the process proceeds to step S5.

  In step S4, the signal generator 16 generates a simulated running sound according to the simulated running sound output schedule corresponding to the head of the schedule, thereby starting the output of the simulated running sound and ending the flow. The pseudo running sound generated by the signal generator 16 is output via the signal amplifier 17 and the speaker 18 as described above.

  In step S5, when the pseudo running sound is being output from the speaker 18 (Yes in step S5), the process proceeds to step S6. If the simulated running sound is not being output from the speaker 18 (No in step S5), the flow ends. In step S6, the signal generator 16 stops generating the simulated running sound, the output of the simulated running sound from the speaker 18 is stopped, and the flow ends.

  Moreover, the process regarding the schedule preparation in the control apparatus 15 after the output of the simulated running sound in the simulated running sound generation apparatus 1 is complete | finished is demonstrated using FIG. FIG. 10 is a flowchart showing a flow of processing relating to schedule creation in the control device 15 after the simulated running sound generation device 1 finishes outputting the simulated running sound. This flow is started as needed when the output of the simulated running sound from the speaker 18 is finished.

  In step S11, the scheduled output of the simulated running sound for which the output of the simulated running sound has been completed is deleted from the schedule, and the process proceeds to step S12. In step S12, when the schedule exists (Yes in step S12), the process proceeds to step S13. If the schedule does not exist (No in step S12), the flow ends.

  In step S13, by causing the signal generator 16 to generate a simulated running sound according to the schedule for outputting the simulated running sound corresponding to the head of the schedule, the output of the simulated running sound is started and the flow ends. The pseudo running sound generated by the signal generator 16 is output via the signal amplifier 17 and the speaker 18 as described above.

  Further, a specific example of creating a schedule and outputting simulated running sound in the simulated running sound generating apparatus 1 will be described with reference to FIGS. 11, 12 (a), and 12 (b). FIG. 11 is a diagram for explaining an example of a travel route of an electric vehicle on which the simulated travel sound generation device 1 is mounted. In addition, the square frame in FIG. 11 has shown the parking lot, and the broken line has shown the driving route of the electric vehicle. In addition, an ellipse C indicated by a dotted line is a communication range of the roadside device 3 installed at the parking lot entrance, an ellipse D indicated by a dotted line is a communication range of the mobile terminal 2 carried by the pedestrian F, and an ellipse E indicated by a dotted line Indicates a communication range for the roadside machine 3 installed at the parking lot exit. In addition, the same identification ID shall use the roadside machine 3 installed in the parking lot entrance, and the roadside machine 3 installed in the parking lot exit. FIGS. 12A and 12B are diagrams schematically showing an example of a schedule.

  Here, as shown in FIG. 11, an electric vehicle (for example, electric vehicle A) equipped with the simulated running sound generator 1 enters the parking lot and passes a pedestrian F carrying the mobile terminal 2 on the way. I will explain the case of leaving the parking lot. It is assumed that the mobile terminal 2 carried by the pedestrian F transmits the simulated running sound output request information requesting the output of the simulated running sound for the output time “5 seconds” once every 3 seconds. Further, the priority information included in the simulated traveling sound output request information of the roadside machine 3 is “01” in the example of FIG. 3, and the priority information included in the simulated traveling sound output request information of the mobile terminal 2 is the example of FIG. “03”.

  First, when the electric vehicle A enters the communication range (ellipse C) of the roadside machine 3 at the entrance of the parking lot, the simulated running sound output request information (output request “1”) transmitted by the roadside machine 3 is used. Receive. The output request “1” includes priority information “01”, identification ID “01”, volume information “03”, sound quality information “02”, and output time information “until a pseudo driving sound stop request is received”. Is included.

  As a result, the simulated running sound generator 1 of the electric vehicle A has priority information “01”, identification ID “01”, volume information “03”, sound quality information “02”, output as shown in FIG. A schedule composed of a schedule of output of the simulated running sound (designated to be output “1”) with time information “until the request for stopping the simulated running sound is received” is created. Then, the pseudo driving sound is output with the volume information “03”, the sound quality “02”, and the output time “until the pseudo driving sound stop request is received” indicated by the volume information, sound quality information, and output time information of the scheduled output “1”. To do.

  Next, when the electric vehicle A approaches the pedestrian F and enters the communication range (ellipse D) of the portable terminal 2 carried by the pedestrian F, the pseudo running sound output request transmitted by the portable terminal 2 is transmitted. Information (output request “2”) is received. The output request “2” includes priority information “03”, identification ID “02”, volume information “10”, sound quality information “05”, and output time information “5 seconds”.

  The priority information of the output request “1” is “01”, whereas the priority information of the output request “2” is “03”, and the output request “2” is more than the output request “1”. Since the numerical value of the priority is large, the simulated running sound generation device 1 of the electric vehicle A is based on the output information “2”, the priority information “03”, the identification ID “02”, as shown in FIG. Create a schedule that gives priority to the output schedule “1” for the output schedule of the simulated running sound (scheduled to be output “2”) with volume information “10”, sound quality information “05”, and output time information “5 seconds” To do. That is, the schedule is created by adding the output schedule “2” to be output before the output schedule “1”. Then, the pseudo running sound is output at the volume “10”, the sound quality “05”, and the output time “5 seconds” indicated by the volume information, sound quality information, and output time information of the output schedule “2”.

  Thereafter, when the electric vehicle A is out of the communication range (ellipse D) of the portable terminal 2 carried by the pedestrian F and the output request “2” is not received, the schedule returns to the state shown in FIG. , Original volume, sound quality, output time (that is, volume “03”, sound quality “02”, output time “pseudo driving sound stop request instructed by volume information, sound quality information, output time information of output schedule“ 1 ” A pseudo running sound is output in “until reception”.

  Finally, when the electric vehicle A enters the communication range (ellipse E) of the roadside machine 3 at the parking lot exit, the pseudo running sound stop request information (stop request “3”) transmitted by the roadside machine 3 is transmitted. ). The stop request “3” includes the identification ID “01”. Here, since the identification ID “01” of the stop request “3” is the same as the identification ID “01” of the output request “1”, the output schedule “1” is deleted from the schedule in the state shown in FIG. To do. Then, when the output schedule “1” is deleted from the schedule, the schedule disappears, so the simulated running sound generation device 1 of the electric vehicle A stops outputting the simulated running sound.

  In addition, when the simulated running sound output request information from the mobile terminal 2 received by the communication unit 11 is sent, the control device 15 decodes the simulated running sound output request information. Then, encoding or the like is performed on the set of pseudo running sound output request information derived from the mobile terminal 2 and sent to the communication unit 11. In this case, the type of the simulated running sound output request information is “information ID: 01”. Then, the control device 15 causes the simulated running sound output request information “01” to be transmitted from the communication unit 11 to the simulated running sound generation device 1 mounted on another vehicle.

  The pseudo running sound output request information “01” derived from the mobile terminal 2 is transmitted only for a certain period (for example, several seconds) after receiving the pseudo running sound output request information from the mobile terminal 2. That's fine.

  Furthermore, when the detection result of the dangerous object is sent from the dangerous object detection device 12, the control device 15 generates pseudo running sound output request information based on the detection result. Therefore, the control apparatus 15 is equivalent to the onboard equipment side output control information generation part of a claim. As an example, the identification ID, the priority information, the volume information, the sound quality information, and the output time may be configured to use each information prepared in advance for the dangerous object. In addition, when the dangerous object detection device 12 can also detect the position of the dangerous object, the detected dangerous object position may be used as position information.

  In addition, when the pseudo traveling sound output request information of the pseudo traveling sound output request information from the mobile terminal 2 is received by the communication unit 11, a set of pseudo traveling sound output request information derived from the mobile terminal 2 is further summarized. The communication unit 11 may be configured to transmit the simulated running sound generator 1 mounted on another vehicle.

  Note that the simulated running sound output request information from the communication unit 11 is periodically (for example, every several hundred milliseconds, for example) while communication with the simulated running sound generating device 1 mounted on another vehicle is established. ).

  According to the above configuration, not only when the dangerous object detection device 12 of the own vehicle detects that there is a dangerous object around the own vehicle, the simulated running sound output request information is transmitted to the mobile terminal 2, the roadside machine 3, Even when received from the simulated running sound generator 1 mounted on another vehicle, the simulated running sound can be output. Therefore, it is possible to output a simulated running sound when there is a danger object around the host vehicle or when there is a high possibility that it exists without being affected by the blind spot detected by the danger object detection device 12.

  For example, even when a person carrying the mobile terminal 2 is present in the blind spot around the host vehicle, the simulated travel sound can be output according to the simulated travel sound output request information transmitted from the mobile terminal 2. Further, by installing the roadside machine 3 in a place where there is a lot of traffic, even if there is a danger target in the blind spot around the own vehicle in the vicinity of the roadside machine 3, the simulated running sound transmitted from the roadside machine 3 A pseudo running sound can be output according to the output request information. Therefore, according to the above configuration, it is possible to more surely output the simulated running sound that matches the actual situation.

  Further, according to the above configuration, since the volume for outputting the simulated running sound is determined based on the volume information of the simulated running sound, the volume of the simulated running sound requested from the mobile terminal 2 or the roadside device 3 is determined. This makes it possible to output a simulated running sound. Therefore, for example, when the simulated running sound is output for an object such as an elderly person that requires a greater simulated running sound, or when the simulated running sound is output for a place where the noise is loud, It is possible to make the alerting more effective by increasing.

  Furthermore, according to the above configuration, since the direction and volume for outputting the simulated running sound are determined based on the position information, the risk object detected by the person carrying the mobile terminal 2 or the danger object detection device 12 or 32 is determined. The simulated running sound is output in the direction in which the vehicle exists, or the simulated running sound is output at a volume corresponding to the distance to the dangerous object detected by the person carrying the portable terminal 2 or the dangerous object detection device 12 or 32. It becomes possible to do. Therefore, it becomes possible to make alerting more effectively.

  Further, according to the above configuration, when the dangerous object around the roadside machine 3 is detected by the dangerous object detection device 32 of the roadside machine 3, the simulated running sound output request information generated based on the detection result of the dangerous object is obtained. Since it can be transmitted from the roadside machine 3 to the simulated running sound generating device 1, even if there is a danger target in the blind spot around the vehicle near the roadside machine 3, a simulated running sound is output. Alerts can be made.

  Furthermore, according to the above configuration, the simulated traveling sound output request information transmitted from the mobile terminal 2 is collected by the roadside device 3, and the collected simulated traveling sound output request information is collected from the roadside device 3 by the simulated traveling sound generator 1. Will be sent to. Therefore, the cautions due to the output of the simulated traveling sound that the portable terminal 2 being carried exists outside the range that can communicate with the simulated traveling sound generation device 1 due to the influence of an obstacle or the like, but is present in the vicinity of the own vehicle. Even for a person who prefers to be alerted, a simulated running sound can be output and alerted.

  Further, according to the above configuration, the simulated traveling sound output request information transmitted from the mobile terminal 2 is collected by, for example, the simulated traveling sound generation device 1 of the electric vehicle B, and the collected simulated traveling sound output request information is stored in the electric vehicle. It can be transmitted from the simulated running sound generator 1 of B to the simulated running sound generator 1 of the electric vehicle A. Therefore, the simulated traveling in which the portable terminal 2 being carried exists outside the range where it can communicate with the simulated traveling sound generator 1 of the electric vehicle A due to an obstacle or the like, but is present in the vicinity of the electric vehicle A. Even for a person who should be alerted by sound output, it is possible to alert the user by outputting a simulated running sound from the electric vehicle A.

  Further, according to the above configuration, when the dangerous object around the electric vehicle B is detected by the dangerous object detection device 12 of the electric vehicle B, the pseudo running sound output request information generated based on the detection result of the dangerous object is obtained. Since it is possible to transmit to the simulated running sound generator 1 of the electric vehicle A, even if there is a danger target in the blind spot around the electric vehicle A in the vicinity of the electric vehicle B, the simulated running sound is generated from the electric vehicle A. A sound can be output to alert.

  In the above-described embodiment, the configuration is shown in which the simulated traveling sound generation device 1 transmits the simulated traveling sound output request information derived from the mobile terminal 2 to the simulated traveling sound generation device 1 installed in another vehicle. However, this is not necessarily the case. For example, the simulated traveling sound generation device 1 may be configured not to have a function of transmitting the simulated traveling sound output request information derived from the mobile terminal 2 to the simulated traveling sound generation device 1 mounted on another vehicle.

  In the above-described embodiment, the configuration in which the simulated traveling sound generation device 1 includes the danger target detection device 12 is shown, but the configuration is not necessarily limited thereto. For example, the simulated running sound generation device 1 may be configured not to include the danger target detection device 12.

  Further, in the above-described embodiment, the configuration in which the simulated running sound generation device 1 includes the position detector 14 is shown, but the configuration is not necessarily limited thereto. For example, the simulated running sound generation device 1 may be configured not to include the danger target detection device 12.

  In the above-described embodiment, the configuration in which the roadside machine 3 includes the danger target detection device 32 is shown, but the configuration is not necessarily limited thereto. For example, the roadside machine 3 may be configured not to include the danger object detection device 32.

  Moreover, although the roadside machine 3 received the simulated traveling sound output request information derived from the mobile terminal 2 from the mobile terminal 2 in the above-described embodiment, the configuration is not necessarily limited thereto. For example, the roadside device 3 may have a configuration that does not have a function of receiving the pseudo running sound output request information derived from the mobile terminal 2 from the mobile terminal 2.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims, and the technical means disclosed in different embodiments can be appropriately combined. Such embodiments are also included in the technical scope of the present invention.
