<First Embodiment>
As shown in FIG. 1, a hybrid vehicle 1000 equipped with a vehicle alarm device 610 according to the present embodiment includes an engine 100, a motor generator (hereinafter abbreviated as MG) (1) 200, and a PCU. (Power Control Unit) 300, battery 400 as a power storage device, MG (2) 500, communication device 650, display device 660, and HV_ECU (Hybrid Vehicle Electronic Control Unit) 600 connected to all of them including.

  Engine 100 burns a mixture of fuel and air to rotate a crankshaft (not shown) to generate driving force. The driving force generated by engine 100 is divided into two paths by power split mechanism 700. On the other hand, this is a path for driving the wheel 900 via the speed reducer 800. The other is a path for driving MG (1) 200 to generate power.

  MG (1) 200 is driven by the power of engine 100 divided by power split mechanism 700 to generate power. The electric power generated by MG (1) 200 is selectively used depending on the driving state of the vehicle and the state of charge (SOC) of battery 400. For example, during normal traveling or sudden acceleration, the electric power generated by MG (1) 200 is supplied to MG (2) 500 via PCU 300.

  On the other hand, when the SOC of battery 400 is lower than a predetermined value, the power generated by MG (1) 200 is converted from AC power to DC power by inverter 302 of PCU 300, and the voltage is adjusted by converter 304. And then stored in the battery 400.

  A battery 400 that is a power storage device is an assembled battery that is configured by further connecting a plurality of battery modules in which a plurality of battery cells are integrated in series. Note that a capacitor (capacitor) may be used instead of the battery 400 as the power storage device.

  MG (2) 500 is a three-phase AC rotating electric machine. MG (2) 500 is driven by at least one of the electric power stored in battery 400 and the electric power generated by MG (1) 200.

  The driving force of MG (2) 500 is transmitted to wheel 900 via reduction gear 800. Thus, MG (2) 500 assists engine 100 to cause the vehicle to travel, or causes the vehicle to travel only by the driving force from MG (2) 500.

  At the time of regenerative braking of the vehicle, MG (2) 500 is driven by wheels 900 via reduction gear 800, and MG (2) 500 is operated as a generator. Thereby, MG (2) 500 operates as a regenerative brake that converts braking energy into electric power. The electric power generated by MG (2) 500 is stored in battery 400 via inverter 302 and converter 304.

  The HV_ECU 600 includes a CPU (Central Processing Unit) 602 and a memory 604. The CPU 602 performs arithmetic processing based on the traveling state of the vehicle, the accelerator opening, the amount of depression of the brake pedal, the shift position, the SOC of the battery 400, the map and program stored in the memory 604, and the like. Thereby, hybrid ECU 600 controls the devices mounted on the vehicle so that the vehicle is in a desired driving state.

  Communication device 650 communicates information bidirectionally with a base station (not shown) outside vehicle 1000. For example, the communication device 650 receives information from the communication network via the base station. The communication network may be the Internet or a dedicated communication line. In the present embodiment, the communication device 650 may use a well-known technique, and therefore details thereof will not be described. The display device 660 is provided in the vehicle compartment and displays various information. Display device 660 is, for example, an LCD (Liquid Crystal Display).

  Alarm device 610 generates an alarm for the surroundings of vehicle 1000. As shown in FIG. 2, the alarm device 610 is provided on a control device 612 communicably connected to the HV-ECU 600, a horn A630, a horn B632, and a driver's seat handle (not shown), and the horn A630. And an operation switch 642 for operating the horn B 632 and a sound generator 634.

  The horn A630 generates a horn (1) that satisfies legal standards. The horn A630 is connected to the power source 628 via the conduction switch (1) 618. When the continuity switch (1) 618 is turned on, the power from the power source 628 is supplied to the horn A630. The horn A630 generates the horn (1) when power is supplied from the power source 628. The conduction switch (1) 618 is kept in the cut-off state by the elastic body 624.

  That is, the elastic body 624 is provided so that the contacts at both ends of the conduction switch (1) 618 have a predetermined distance from each of the contact connected to the power source 628 and the contact connected to the horn B. It is done. 2 is applied to the conduction switch (1) 618, the elastic body 624 contracts, and the contacts at both ends of the conduction switch (1) 618 are connected to the power source 628 and a horn. In contact with the contact point connected to B, the conduction switch (1) 618 becomes a conduction state.

  The horn B632 generates the horn (2) that satisfies any one of the condition that the volume is lower than the volume of the horn (1) of the horn A630 and the condition that it is different from the horn (1). The horn (2) may be a sound having a volume or a mode that does not cause discomfort to the people around the vehicle 1000. For example, the horn (2) may be a gentle tone or melody with a small stimulus to human hearing, or a horn. A horn with a lower volume than (1) may be used. The horn B632 is connected to the power source 628 via the conduction switch (2) 620. When the continuity switch (2) 620 becomes conductive, the power of the power source 628 is supplied to the horn B632. The horn B632 generates the horn (2) when electric power is supplied from the power source 628. The conduction switch (2) 620 is kept in a cut-off state by an elastic body 626 having a spring constant smaller than that of the elastic body 624.

  That is, the elastic body 626 is provided so that the contacts at both ends of the conduction switch (2) 620 have a predetermined distance from each of the contact connected to the power source 628 and the contact connected to the horn B. It is done. 2 is applied to the conduction switch (2) 620, the elastic body 626 contracts, and the contacts on both ends of the conduction switch (2) 620 are connected to the power source 628 and a horn. In contact with the contact point connected to B, the conduction switch (2) 620 is in a conduction state.

  The operation switch 642 includes a conduction switch (1) 618 and a conduction switch (2) 620 that are provided in series in the vertical direction in FIG. The conduction switch (2) 620 is provided with a member that transmits an operating force to the conduction switch (1) 618 side through the elastic body 626 when the conduction switch (2) 620 moves downward in the drawing by a predetermined distance. The operation switch 642 generates at least one of the horn (1) and the horn (2) according to the operation force. That is, when an operation force greater than a predetermined value is applied to the operation switch 642, the conduction switch (1) 618 becomes conductive, and when the operation force is smaller than the predetermined force, the conduction switch (2) 620 becomes conductive. It becomes a state.

  Specifically, when an operation force is applied to the operation switch 642 from above in FIG. 2, first, the elastic body 626 having a small spring constant is reduced, and an operation force exceeding the elastic force of the elastic body 626 is applied. The conduction switch (2) 620 is turned on. At this time, the horn (2) is generated from the horn B632.

  When the conduction switch (2) 620 moves downward by a predetermined distance, the operating force is transmitted to the conduction switch (1) 618. The conduction switch (2) 620 has a structure that moves following the conduction switch (1) 618 after the conduction switch (2) 620 enters the conduction state. Therefore, when the elastic body 624 is contracted and a predetermined operating force is applied, the operating force exceeds the elastic force of the elastic body 624, and the conduction switch (1) 618 is turned on. At this time, the horn (1) is generated by the horn A630. In this manner, the horn A 630 and the horn B 632 generate the horn (1) and the horn (2) according to the operation force. Note that a relay circuit or the like may be provided between the circuits of the horn A630 and the horn B632 so that when the horn A630 and the power source 628 are in a conductive state, the horn B632 and the power source 628 are in an interrupted state. In this way, the horn (1) and the horn (2) can be used properly by properly using the operation force in one operation switch 642.

  The continuity switch (3) 622 is connected to the horn B632 in parallel to the continuity switch (2) 620. The conduction switch (3) 622 is controlled to either a conduction state or a cutoff state in accordance with a control signal from the control device 612.

  Sound generator 634 includes a speaker (not shown) provided in the interior of vehicle 1000. The sound generation device 634 generates a sound of a predetermined mode from the speaker in response to a control signal from the control device 612. The sound of the predetermined mode is not particularly limited. For example, it may be the same mode as the second horn or a different mode or a melody. There may be. In the present embodiment, control device 612 generates a sound in a predetermined mode by sound generator 634 from the speaker, along with the generation of horn (2) by horn B632.

  Hereinafter, with reference to FIG. 3, a control structure of a program executed by control device 612 of vehicle alarm device 610 according to the present embodiment will be described.

  In step (hereinafter, step is described as S) 1000, control device 612 determines whether or not EV (Electric Vehicle) travel is being performed. “EV traveling” refers to traveling of the vehicle by the driving force of MG (2) 500 when engine 100 is stopped. Control device 612 receives from HV-ECU 600 a signal indicating that the state of engine 100 and vehicle 1000 are traveling by the driving force of MG (2) 500, and determines whether or not EV traveling is being performed. If it is determined that the vehicle is traveling EV (YES in S1000), the process proceeds to S1200. If not (NO in S1000), the process proceeds to S1100.

  In S1100, control device 612 determines whether or not the rotational speed of engine 100 is greater than a predetermined rotational speed n. The “predetermined number of revolutions n” is not particularly limited as long as it is the number of revolutions of the engine 100 where the sound generated from the vehicle is reduced. Control device 612 may receive a signal corresponding to the rotational speed of engine 100 from HV-ECU 600, or may receive a signal corresponding to the rotational speed of engine 100 from the engine ECU (not shown). May be. If the rotational speed of engine 100 is greater than a predetermined rotational speed n (YES in S1100), the process proceeds to S1300. If not (NO in S1100), the process proceeds to S1200.

  In S1200, control device 612 turns on conduction switch (3) 622. That is, the control device 612 controls the conduction switch (3) 622 to be in a conduction state. In S1300, control device 612 turns off conduction switch (3) 622. That is, the control device 612 controls the conduction switch (3) 622 so as to be in a cutoff state.

  An operation of control device 612 of vehicle alarm device 610 according to the present embodiment based on the above-described structure and flowchart will be described.

  If EV traveling is performed while the vehicle is traveling (YES in S1000), conduction switch (3) 622 is turned on (S1200), and horn (2) is generated. When engine 100 is started (NO in S1000) and engine 100 has a rotation speed greater than a predetermined rotation speed n (YES in S1100), conduction switch (3) 622 is turned off ( S1300). Further, even if engine 100 is started (NO in S1000), conduction switch (3) 622 is turned on when engine 100 has a rotation speed smaller than a predetermined rotation speed n (NO in S1100). (S1200), a horn (2) is generated.

  As described above, according to the vehicle alarm device according to the present embodiment, when the hybrid vehicle equipped with the MG (2) and the engine is traveling with the driving force of the MG (2), If the horn (2) is generated by the horn B, the person around the vehicle can be made aware of the presence of the vehicle. Since the horn (2) satisfies at least one of the condition that the volume of the horn (1) is lower than that of the horn (1) and the condition that the stimulus given to human hearing is a gentle tone, the horn (2) is frequently used. Even if this occurs, it is possible to alert the people around the vehicle without causing discomfort. Therefore, it is possible to provide a vehicle alarm device that can alert a person around the vehicle without causing discomfort.

  In addition, the control device controls the horn B so that the horn (2) is generated when traveling by the driving force of the MG (2). As a result, if the horn (2) is generated when the sound generated from the vehicle when the vehicle is driven by the driving force of the MG (2) is small, attention is given without causing discomfort to the people around the vehicle. Furthermore, since the horn (2) can be generated without the driver's operation, the operation load on the driver can be reduced.

  Further, the control device performs control so that the horn (2) is generated when the vehicle travels according to the state of the vehicle related to the sound generated from the vehicle, that is, the engine speed. As a result, when the horn (2) is generated when the engine speed is low and the sound generated from the vehicle is small, it is possible to call attention without causing discomfort to people around the vehicle, Since the horn (2) can be generated without being operated by the driver, the operation load on the driver can be reduced.

  In the present embodiment, the horn (2) is generated when the rotational speed of the engine 100 is smaller than the predetermined rotational speed n. However, the engine 100 is particularly suitable if it is in a state related to the sound generated from the vehicle. It is not limited to the number of rotations. For example, the horn (2) may be generated when the detected vehicle speed is equal to or lower than a predetermined speed. When the vehicle speed decreases, the sound generated from the vehicle, such as tire pattern noise, decreases. For this reason, when the vehicle speed is lower than a predetermined vehicle speed when the vehicle is running, when the control is performed so that the horn (2) is generated, when the sound generated from the vehicle is small, Can be recognized. Or you may make it set the contribution rate (weighting coefficient) of influence to the sound which generate | occur | produces from a vehicle about a vehicle speed and an engine speed. That is, the horn (2) may be generated when the sum of values obtained by multiplying the detected engine speed and vehicle speed by the respective weighting coefficients is equal to or less than a predetermined value.

  Preferably, the control device may generate a horn (2) when the vehicle starts. If it does in this way, when the sound of a drive source at the time of the start of the parked vehicle is small, the presence of a vehicle can be made to recognize the people around the vehicle.

  In addition, by properly using the operation force in one operation switch, at least one of the horn (1) and the horn (2) can be generated, so that the operability can be improved.

  Further, a switch for operating the horn B may be further provided around the passenger seat of the driver's seat vehicle.
