Description

  The present invention relates to a vehicular alarm device for informing the outside of a vehicle that the vehicle is approaching or that the vehicle is stolen.

  Conventional vehicles are mainly gasoline vehicles that run using an engine as a drive source, and pedestrians can recognize a vehicle approaching from behind or from a blind spot by an engine sound generated by the vehicle. However, since a vehicle using an electric motor as a drive source such as an electric vehicle or a hybrid vehicle does not emit an engine sound, it is difficult for a pedestrian to recognize the approach of the vehicle by the engine sound of the vehicle. Therefore, a vehicle equipped with a device that emits a notification sound for notifying a person outside the vehicle, such as a pedestrian, of the approach of the vehicle has been proposed. For example, Patent Document 1 discloses a vehicle approach notification device that, when a vehicle is traveling at a predetermined vehicle speed or less, generates a simulated tire noise sound having the same tone as the tire noise from a speaker provided at the front end of the vehicle. Has been.

  Various proposals for preventing theft of vehicles have been made. For example, Patent Document 2 discloses a vehicle antitheft device that outputs an alarm sound from an alarm sound output device toward the outside of the vehicle when it is determined that the vehicle is in a stolen state.

  However, when notifying the outside of the vehicle that the vehicle is approaching or the vehicle is stolen by outputting an alarm toward the outside of the vehicle, a notification directed to the outside of the vehicle when the alarm cannot be output. It will be impossible to do. For example, when an alarm sound is output by an alarm sound output device such as a speaker, the alarm sound output device is out of order, or the alarm sound output device outputs an output signal due to disconnection. For example, you cannot enter.

  Then, an object of this invention is to provide the alarm device for vehicles which can heighten an alarm effect by alerting as much as possible.

It is a figure which shows the alarm process in this embodiment. It is a figure which shows the non-alarm response process in this embodiment. It is a figure which shows the alarm process in 2nd Embodiment. It is a figure which shows the non-alarm response process in 2nd Embodiment.

  As shown in FIG. 1, a vehicle 1 equipped with a vehicle alarm device of the present invention includes a notification speaker 10 for outputting a notification sound, a warning horn 20 for outputting a warning sound, and a notification speaker. 10 and an alarm controller 30 to which the alarm horn 20 is connected. In the present embodiment, the notification speaker 10 corresponds to notification sound output means, and the warning horn 20 corresponds to warning sound output means.

  The notification speaker 10 is provided in the vicinity of the back of the pair of left and right fog lamps 3 provided below the headlight 2 at the front end of the vehicle 1, and outputs a notification sound toward the outside of the vehicle 1. Further, the diaphragm of the notification speaker 10 is a cone type and is provided toward the rear of the vehicle 1. In the present embodiment, the vehicle 1 is provided with two notification speakers 10. However, the present invention is not limited to this, and for example, only one notification speaker 10 may be provided. More notification speakers 10 may be provided at the rear, side, or the like.

  The warning horn 20 is fixedly disposed behind the front grill 4 at the front end of the vehicle 1 and outputs a warning sound toward the outside of the vehicle. Further, the warning horn 20 is a disk-type horn and is provided in the downward direction of the vehicle 1 so that the warning sound reaches the periphery of the vehicle 1 uniformly. The warning horn 20 may also be used as a horn device that outputs a warning sound by a driver's horn operation.

  The alarm controller 30 is an ECU (Electronic Control Unit). As shown in FIG. 2, the alarm controller 30 controls the output of the alarm sound by the alarm speaker 10 and outputs the alarm sound by the alarm horn 20. The alarm sound output controller 50 is controlled. The notification sound output controller 40 and the warning sound output controller 50 can mutually input and output control signals. In this embodiment, the notification sound output controller 40 corresponds to a notification sound control signal output unit, and the warning sound output controller 50 corresponds to a warning sound output signal output unit.

  The output side of the notification sound output controller 40 is electrically connected to the notification speaker 10 and the drive restriction controller 60. As a result, a notification sound output signal is output from the notification sound output controller 40 to the notification speaker 10, and a drive restriction control signal is output to the drive restriction controller 60. The input side of the notification sound output controller 40 is electrically connected to the speaker output sensor 11 and the vehicle speed detector 41. Thus, the notification sound output detection signal from the speaker output sensor 11 and the vehicle speed detection signal from the vehicle speed detector 41 are input to the notification sound output controller 40.

  The output side of the warning sound output controller 50 is electrically connected to the warning horn 20 and the drive restriction controller 60. As a result, a warning sound output signal is output from the warning sound output controller 50 to the warning horn 20, and a drive restriction control signal is output to the drive restriction controller 60. The input side of the warning sound output controller 50 is electrically connected to the horn output sensor 21 and the theft detector 51. As a result, the warning sound output detection signal from the horn output sensor 21 and the theft detection signal from the theft detector are input to the warning sound output controller 50.

  The speaker output sensor 11 is provided in the notification speaker 10 and outputs a notification sound output detection signal when it is detected that the notification sound is output from the notification speaker 10.

  The horn output sensor 21 is provided in the warning horn 20 and outputs a warning sound output detection signal when detecting that a warning sound is output from the warning horn 20.

  The vehicle speed detector 41 outputs a vehicle speed detection signal when detecting that the vehicle speed of the vehicle 1 is equal to or lower than a predetermined vehicle speed (15 km / h in this embodiment). In the present embodiment, the vehicle speed detector 41 corresponds to vehicle speed determination means.

  The theft detector 51 outputs a theft detection signal when it is detected that the vehicle 1 is in a stolen state. For example, when the door 1 or the trunk is opened without releasing the door lock to the vehicle 1, the door glass is broken, or the power source of the vehicle 1 is illegally started, For example, when the vehicle 1 is inclined at a predetermined angle or more, or when the vehicle 1 has a predetermined impact or more. In the present embodiment, the theft detector 51 corresponds to a theft determination means.

  An output side of the drive restriction controller 60 is an ignition switch (not shown) that is a switch for an ignition device for the engine of the vehicle 1 and a starting device for the electric motor, and a brake device control means (not shown) for controlling the brake device of the vehicle 1. ). As a result, a start limit signal is output from the drive limit controller 60 to the ignition switch, and a brake operation signal is output to the brake device control means. The ignition switch stops the start of the drive source (engine or electric motor) of the vehicle 1 when the start restriction signal is input, and the brake device control means operates the brake device of the vehicle 1 when the brake operation signal is input. In the present embodiment, the drive restriction controller 60 corresponds to output restriction means.

  Next, alarm processing for outputting a notification sound and a warning sound toward the outside of the vehicle 1 will be described with reference to FIG. Note that the processing flow shown in FIG. 3 is executed every predetermined cycle (for example, 4 milliseconds).

  First, in step S11, the alarm controller 30 determines whether or not the vehicle speed of the vehicle 1 is equal to or lower than a predetermined vehicle speed (15 km / h). Specifically, when the notification sound output controller 40 inputs a vehicle speed detection signal from the vehicle speed detector 41, it is determined that the vehicle speed of the vehicle 1 is equal to or lower than a predetermined vehicle speed, and no vehicle speed detection signal is input from the vehicle speed detector 41. In this case, it is determined that the vehicle speed of the vehicle 1 exceeds the predetermined vehicle speed. And when it determines with the vehicle speed of the vehicle 1 being below a predetermined vehicle speed, a process is moved to step S16, and when it determines with the vehicle speed of the vehicle 1 exceeding the predetermined vehicle speed, a process is moved to step S12.

  In step S12, the alarm controller 30 determines whether or not the vehicle 1 is in a stolen state. Specifically, when the warning sound output controller 50 inputs a theft detection signal from the theft detector 51, it is determined that the vehicle 1 is in a theft state, and when the theft detection signal is not input, the vehicle 1 is not in the theft state. Is determined. If it is determined that the vehicle 1 is in a stolen state, the process proceeds to step S13. If it is determined that the vehicle 1 is not in a stolen state, the process proceeds to step S15.

  In step S13, the alarm controller 30 executes a warning sound output process for outputting a warning sound to the outside of the vehicle. Specifically, a warning sound output signal is output from the warning sound output controller 50 to the warning horn 20. Thereby, when the vehicle 1 is in a stolen state, a warning sound is output from the warning horn 20.

  In step S <b> 14, the alarm controller 30 performs a process of turning on a warning flag stored in a warning flag storage area of a RAM (RANDOM ACCESS MEMORY) built in the alarm controller 30. The warning flag is turned on when a warning sound output signal is output to the warning horn 20, and is turned off when a warning sound output signal is not output to the warning horn 20. Therefore, when the warning sound should be output from the warning horn 20, the warning flag is ON. When this process ends, the process moves to a step S16.

  In step S15, the alarm controller 30 performs a process of turning off the notification flag stored in the notification flag storage area of the RAM built in the alarm controller and turning off the warning flag stored in the warning flag storage area. Thereby, when the vehicle speed of the vehicle 1 is not less than the predetermined vehicle speed and is not in a stolen state, both the notification flag and the warning flag are turned off. The notification flag is turned on when a notification sound output signal is output to the notification speaker 10, and is turned off when a notification sound output signal is not output to the notification speaker 10.

  In step S <b> 16, the alarm controller 30 executes a notification sound output process for outputting the notification sound toward the outside of the vehicle. Specifically, a notification sound output signal is output from the notification sound output controller 40 to the notification speaker 10. Thus, when the vehicle speed of the vehicle 1 is equal to or lower than the predetermined vehicle speed and when the vehicle 1 is in a stolen state, a notification sound is output from the notification speaker 10.

  In step S17, the alarm controller 30 performs a process of turning on the notification flag stored in the notification flag storage area. Thereby, when the notification sound output signal is output to the notification speaker 10, the notification flag is turned ON.

  Next, a non-alarm handling process for dealing with a case where a warning is not normally performed will be described with reference to FIG. Note that the processing flow shown in FIG. 4 is executed every predetermined cycle (for example, 4 milliseconds).

  First, in step S21, the alarm controller 30 determines whether or not the notification flag stored in the notification flag storage area is ON. If the notification flag is ON, the process proceeds to step S22. If the notification flag is OFF, the process proceeds to step S23.

  In step S <b> 22, the alarm controller 30 determines whether a notification sound is output from the notification speaker 10. Specifically, when the notification sound output controller 40 receives a notification sound output detection signal from the speaker output sensor 11, it is determined that the notification sound is output from the notification speaker 10. On the other hand, when the notification sound output controller 40 does not input the notification sound output detection signal from the speaker output sensor 11, it is determined that the notification sound is not output from the notification speaker 10. If it is determined that the notification sound is output from the notification speaker 10, the non-alarm handling process is terminated, and if it is determined that the notification sound is not output from the notification speaker 10, the process proceeds to step S25. .

  In step S23, the alarm controller 30 determines whether or not the warning flag stored in the warning flag storage area is ON. If the warning flag is ON, the process proceeds to step S24. If the warning flag is OFF, the non-alarm handling process is terminated.

  In step S <b> 24, the alarm controller 30 determines whether a warning sound is output from the warning horn 20. Specifically, when the warning sound output controller 50 receives a warning sound output detection signal from the horn output sensor 21, it is determined that a warning sound is output from the warning horn 20. On the other hand, when the warning sound output controller 50 does not input the warning sound output detection signal from the horn output sensor 21, it is determined that the warning sound is not output from the warning horn 20. If it is determined that a warning sound is output from the warning horn 20, the non-alarm handling process is terminated, and if it is determined that no warning sound is output from the warning horn 20, the process proceeds to step S25. .

  In step S <b> 25, the alarm controller 30 executes a drive restriction process for restricting the start of the drive source of the vehicle 1 and the travel of the vehicle 1. Specifically, when it is determined that the notification sound is not output from the notification speaker 10 in step S22, a drive restriction control signal is output from the notification sound output controller 40 to the drive restriction controller 60. On the other hand, when it is determined in step S24 that no warning sound is output from the warning horn 20, a drive restriction control signal is output from the warning sound output controller 50 to the drive restriction controller 60. The drive restriction controller 60 that has received the drive restriction control signal outputs a start restriction signal to the ignition switch and also outputs a brake operation signal to the brake device control means. Thereby, when the drive source of the vehicle 1 is not started, the drive source of the vehicle 1 is not started, and when the vehicle 1 is running, the brake of the vehicle 1 is operated. When this process ends, the non-alarm handling process ends.

  As described above, when the vehicle 1 is stolen, a warning sound is output from the warning horn 20 and a notification sound is output from the notification speaker 10. Then, when the notification sound is not output from the notification speaker 10 even though the notification sound output processing is executed, or the warning sound is output from the warning horn 20 even though the warning sound output processing is executed. If not, a drive restriction process for the vehicle 1 is performed.

  Thus, when the vehicle 1 is stolen, the alarm effect can be enhanced by outputting not only the warning sound but also the notification sound at the same time. Further, when the vehicle 1 is stolen, the warning sound output from the warning horn 20 becomes an alarm even if no notification sound is output from the notification speaker 10, and the warning is output even if no warning sound is output from the warning horn 20. The alarm sound output from the speaker 10 is an alarm. Therefore, it is possible to output an alarm indicating that the theft state is more reliable.

  The case where the notification sound is not output even when the notification sound output process is executed includes, for example, a case where a failure occurs in the notification speaker 10, a case where a failure occurs in the notification sound output controller 40, and a notification sound output controller. For example, when the connection between the speaker 40 and the notification speaker 10 is cut off. Further, the case where the warning sound is not output even if the warning sound output procedure is executed is, for example, when a problem occurs in the warning horn 20, a problem occurs in the warning sound output controller 50, and a warning sound output controller. For example, the connection between the alarm 50 and the warning horn 20 is disconnected. In such a case, since the start and running of the drive source of the vehicle 1 are restricted, the crime prevention effect can be further enhanced.

  Next, alarm processing and non-alarm handling processing in the second embodiment will be described with reference to FIGS. 5 and 6. Note that the description of the same or overlapping parts with the above embodiment is omitted.

  In the alarm process, first, in step S31, the alarm controller 30 determines whether or not the vehicle speed of the vehicle 1 is equal to or lower than a predetermined vehicle speed. And when it determines with the vehicle speed of the vehicle 1 being below a predetermined vehicle speed, a process is moved to step S32, and when it determines with the vehicle speed of the vehicle 1 exceeding the predetermined vehicle speed, a process is moved to step S34.

  In step S <b> 32, the alarm controller 30 executes a notification sound output process for outputting a notification sound from the notification speaker 10 toward the outside of the vehicle. When this process ends, the process moves to a step S33.

  In step S33, the alarm controller 30 performs a process of turning on the notification flag stored in the notification flag storage area. When this process ends, the process moves to a step S35.

  In step S34, the alarm controller 30 performs a process of turning off the notification flag stored in the notification flag storage area. When this process ends, the process moves to a step S35.

  In step S35, the alarm controller 30 determines whether or not the vehicle 1 is in a stolen state. If it is determined that the vehicle 1 is in a stolen state, the process proceeds to step S36. If it is determined that the vehicle 1 is not in a stolen state, the process proceeds to step S38.

  In step S36, the alarm controller 30 executes a warning sound output process for outputting a warning sound from the warning horn 20 toward the outside of the vehicle. When this process ends, the process moves to a step S37.

  In step S37, the alarm controller 30 performs a process of turning on the warning flag stored in the warning flag storage area. When this process ends, the alarm process ends.

  In step S38, the alarm controller 30 performs a process of turning off the warning flag stored in the warning flag storage area. When this process ends, the alarm process ends.

  Next, in the non-alarm handling process, in step S41, the alarm controller 30 determines whether or not the notification flag stored in the notification flag storage area is ON. If it is determined that the notification flag is ON, the process proceeds to step S42. If it is determined that the notification flag is OFF, the process proceeds to step S44.

  In step S <b> 42, the alarm controller 30 determines whether a notification sound is output from the notification speaker 10. If it is determined that the notification sound is output from the notification speaker 10, the process proceeds to step S44, and if it is determined that the notification sound is not output from the notification speaker 10, the process proceeds to step S43.

  In step S43, the alarm controller 30 executes a warning sound output process for outputting a warning sound from the warning horn 20 toward the outside of the vehicle. When this process ends, the process moves to a step S47.

  In step S44, the alarm controller 30 determines whether or not the warning flag stored in the warning flag storage area is ON. If it is determined that the warning flag is turned on, the process proceeds to step S45. If it is determined that the warning flag is turned off, the non-alarm handling process is terminated.

  In step S <b> 45, the alarm controller 30 determines whether a warning sound is output from the warning horn 20. If it is determined that a warning sound is output from the warning horn 20, the non-alarm handling process is terminated, and if it is determined that no warning sound is output from the warning horn 20, the process proceeds to step S46. .

  In step S46, the alarm controller 30 executes a notification sound output process for outputting a notification sound from the notification speaker 10 to the outside of the vehicle. When this process ends, the process moves to a step S47.

  In step S <b> 47, the alarm controller 30 executes a drive restriction process for restricting starting of the drive source of the vehicle 1 and travel of the vehicle 1. Specifically, the drive restriction controller 60 that outputs a drive restriction control signal to the drive restriction controller 60 and inputs the dynamic restriction control signal outputs a start restriction signal to the ignition switch, and also to the brake device control means. Output a brake activation signal. When this process ends, the non-alarm handling process ends.

  Thus, in the second embodiment, normally, when the vehicle speed of the vehicle 1 is equal to or lower than the predetermined vehicle speed, a notification sound is output from the notification speaker 10, and when the vehicle 1 is in a stolen state, a warning horn 20 Output a warning sound. However, if the notification sound is not output from the notification speaker 10 even though the notification sound output process is executed, a warning sound is output from the warning horn 20. Further, when the warning sound is not output from the warning horn 20 even though the warning sound output process is executed, the notification sound is output from the notification speaker 10. That is, when the notification sound cannot be output, a warning sound is output instead of the notification sound, and when the warning sound cannot be output, the notification sound is output instead of the warning sound.

  Therefore, when the vehicle speed of the vehicle 1 is equal to or lower than the predetermined vehicle speed, a warning sound is output as an alternative even if the notification sound cannot be output due to a malfunction of the notification speaker 10. Can be performed reliably. Further, even if the warning sound cannot be output due to a malfunction of the warning horn 20 or the like when the vehicle 1 is in a stolen state, the notification sound is output as an alternative, so that the vehicle 1 is in a stolen state. The alarm can be reliably performed.

  When a signal is not normally output from the notification sound output controller 40 to the notification speaker 10, a warning sound is output from the warning horn 20 regardless of the state of the notification flag. When a signal is not normally output from the warning sound output controller 50 to the warning horn 20, a notification sound may be output from the notification speaker 10 regardless of the state of the warning flag. . In this case, when the notification sound output controller 40 determines that the notification sound output signal cannot be normally output because the connection between the notification sound output controller 40 and the notification speaker 10 is broken, a warning is given. A warning sound output instruction signal is output to the sound output controller 50. Further, when the warning sound output controller 50 determines that the warning sound output signal cannot be normally output due to a disconnection of the connection between the warning sound output controller 50 and the warning horn 20, the notification sound A notification sound output instruction signal is output to the output controller 40.

  In the present embodiment and the second embodiment described above, when the vehicle speed of the vehicle 1 is equal to or lower than the predetermined vehicle speed, a notification sound for notifying the approach of the vehicle 1 is output. The notification sound for notifying the approach of the vehicle 1 may be output when the above condition is satisfied (for example, there is an object such as a pedestrian in the traveling direction of the vehicle 1).
