[Configuration of control device]
Next, the configuration of the control device for the emergency braking indicator lamp 4a of the saddle riding type vehicle 1 in the present embodiment will be described in detail with reference to FIG.

  As shown in FIG. 1, the control device 30 for the emergency braking indicator light 4a of the saddle riding type vehicle 1 in the present embodiment is configured by an electronic control device such as an ECU (Electronic Control Unit). According to the operating state of the front wheel brake (FR brake) 19, specifically, the control device 30 includes a front wheel brake switch 31 that outputs an ON signal when the brake lever 12 is gripped and a rear wheel brake (RR brake) 20. Specifically, the rear wheel brake switch 32 that outputs an ON signal when the brake pedal 18 is depressed, the vehicle speed sensor 33 that outputs an electric signal corresponding to the vehicle speed of the saddle riding type vehicle 1, and the front wheel 2 according to the operating state. In addition, an ABS control device 34 that controls an ABS (Anti-lock Braking System) that is freely controllable so as not to lock the rear wheels 3 during braking and that is not illustrated is electrically connected. Has been. Note that the ABS may be omitted depending on the specifications of the saddle riding type vehicle 1.

  Specifically, the control device 30 includes a vehicle speed calculation unit 30a, a deceleration calculation unit 30b, a sudden deceleration generation determination unit 30c, a stop intention determination unit 30d, an emergency braking signal generation output determination unit 30e, an ABS operation determination unit 30f, an emergency braking display. A permission determination unit 30g, a blinking cycle calculation unit 30h, and an emergency braking indicator light drive signal generation output unit 30i are provided. Each of these units is shown as a functional block. Although details of the functions of these units will be described later, the vehicle speed calculation unit 30a calculates the vehicle speed of the saddle riding type vehicle 1 based on the electric signal output from the vehicle speed sensor 33, and the deceleration calculation unit 30b. Is to calculate the deceleration of the saddle riding type vehicle 1 from the time change of the vehicle speed of the saddle riding type vehicle 1 based on the electric signal output from the vehicle speed sensor 33. The rapid deceleration occurrence determination unit 30c Based on the deceleration of the riding type vehicle 1, it is determined whether or not a rapid deceleration has occurred in the saddle riding type vehicle 1, and the stop intention determination unit 30 d is not a braking operation of only the RR brake 20 but FR When the braking operation of the brake 19 is performed, it is determined that the driver intends to stop, and the emergency braking signal generation output determination unit 30e is configured to generate a sudden deceleration in the saddle riding type vehicle 1, or At high ABS speed When an operation occurs, it is determined that an emergency braking signal indicating that the saddle riding type vehicle 1 is in an emergency braking state should be generated and output, and an emergency braking signal is output. The unit 30f determines that an operation at a high vehicle speed of the ABS has occurred when the vehicle speed of the saddle riding type vehicle 1 is equal to or higher than a predetermined vehicle speed and the ABS is operating, and an emergency braking display permission determination unit 30g is a judgment for permitting the flashing operation of the emergency brake indicator light 4a when it is determined that an emergency braking signal is input and it is determined that the driver intends to stop, and a flashing period calculating unit 30h. Is to calculate the blinking cycle of the emergency braking indicator lamp 4a according to the deceleration of the saddle riding type vehicle 1 or the vehicle speed of the saddle riding type vehicle 1, and the emergency braking indicator lamp driving signal generation output unit 30i Emergency braking indicator light according to blinking cycle To blink a, it is to generate and output a drive signal to the emergency braking indicator 4a. The control device 30 includes a memory (not shown), and reads and uses various arithmetic processing programs and data stored in the memory as necessary.

  The control device 30 having such a configuration promptly and clearly notifies the succeeding vehicle that the vehicle is in an emergency braking state by executing the following emergency braking indicator light control process. Hereinafter, the operation of the control device 30 when the emergency braking indicator light control process is executed will be described with reference to FIG.

[Emergency braking indicator light control processing]
FIG. 2 is a data flow diagram showing the emergency brake indicator light control process of the control device 30 of the emergency brake indicator light 4a of the saddle riding type vehicle 1 according to this embodiment, together with the data flow related thereto. In addition, the arrow in a figure has shown this data flow.

  The emergency braking indicator light control process shown in FIG. 2 starts when the ignition switch (not shown) of the saddle riding type vehicle 1 is switched from the OFF state to the ON state, and the ignition switch of the saddle riding type vehicle 1 is in the ON state. During this period, it is repeatedly executed at a predetermined control cycle.

In the process P1, the deceleration calculation unit 30b performs the saddle type vehicle from the change in the vehicle speed of the saddle type vehicle 1 based on the electrical signal output from the vehicle speed sensor 33 during or before the execution of this process. Since the deceleration of 1 is calculated, the rapid deceleration occurrence determination unit 30c is converted into a predetermined deceleration (for example, 60 m / s ²⁾ based on the data indicating the deceleration calculated by the deceleration calculation unit 30b. ) It is determined whether or not a rapid deceleration has occurred by determining whether or not it is above. That is, as a result of the determination, when the deceleration of the saddle riding type vehicle 1 is equal to or greater than the predetermined deceleration, the rapid deceleration generation determining unit 30c determines that the rapid deceleration has occurred in the saddle riding type vehicle 1. On the other hand, as a result of the determination, if the deceleration of the saddle riding type vehicle 1 is not equal to or greater than the predetermined deceleration, the rapid deceleration occurrence determination unit 30c determines that no rapid deceleration has occurred in the saddle riding type vehicle 1. The deceleration calculation unit 30b may calculate the deceleration of the saddle riding type vehicle 1 based on an electrical signal output from an acceleration sensor (not shown) instead of an electrical signal output from the vehicle speed sensor 33. .

  In the process P2, the vehicle speed calculation unit 30a calculates the vehicle speed of the straddle-type vehicle 1 based on the electrical signal output from the vehicle speed sensor 33 during or before the execution of this process. Data indicating the vehicle speed calculated by the vehicle speed calculation unit 30a by the ABS operation determination unit 30f because the control device 34 knows whether or not the ABS is operating before or after executing this process. Based on the above, it is determined whether or not the vehicle speed of the saddle riding type vehicle 1 is equal to or higher than a predetermined vehicle speed (for example, 50 km / h), and the ABS operation determination unit 30f determines whether or not the ABS is detected by the ABS control device 34. Whether or not the ABS is operating is determined based on the data indicating. As a result of the determination, when the vehicle speed is equal to or higher than the predetermined vehicle speed and the ABS is operating, the ABS operation determination unit 30f determines that the operation at the high vehicle speed of the ABS has occurred. On the other hand, if it is determined that the vehicle speed is not higher than the predetermined vehicle speed or that the ABS is not operating, the ABS operation determination unit 30f does not determine that the operation at the high vehicle speed of the ABS has occurred. .

  In the process P3, whether or not the stop intention determination unit 30d has output an ON signal indicating that the braking operation of the FR brake 19 is performed from the front wheel brake switch 31 based on the electrical signal output from the front wheel brake switch 31. Based on the electrical signal output from the rear wheel brake switch 32, it is determined whether or not an ON signal indicating that the braking operation of the RR brake 20 is performed is output from the rear wheel brake switch 32. As a result of the determination, an ON signal is output from the front wheel brake switch 31 and an ON signal is not output from the rear wheel brake switch 32, or an ON signal is output from both the front wheel brake switch 31 and the rear wheel brake switch 32. In this case, the stop intention determination unit 30d brakes the straddle-type vehicle 1 instead of the braking operation only for the RR brake 20 whose main purpose is to control the vehicle body behavior during travel of the straddle-type vehicle 1. Since the braking operation of the FR brake 19 is mainly performed, it is determined that the driver intends to stop. On the other hand, as a result of the determination, when the ON signal is output only from the rear wheel brake switch 32, the stop intention determination unit 30d is mainly intended to control the vehicle body behavior when the saddle riding type vehicle 1 travels. Since the braking operation of only the brake 20 is performed, it is determined that the driver does not intend to stop.

  In the process P4, the rapid deceleration occurrence determination unit 30c determines whether or not a rapid deceleration has occurred in the saddle type vehicle 1 in the process P1 during or before the execution of this process. In addition, since the ABS operation determination unit 30f determines whether or not the operation at the high vehicle speed of the ABS has occurred in the processing of the process P2 during or before the execution of this processing, The braking signal generation output determination unit 30e generates data indicating the determination result of whether or not the rapid deceleration obtained in the process P1 has occurred, and the operation of the ABS obtained in the process P2 at a high vehicle speed. Based on the data indicating the result of the determination as to whether or not the vehicle has been operated, it is determined whether or not a rapid deceleration has occurred in the saddle riding type vehicle 1 or whether or not an operation has occurred at a high vehicle speed of the ABS. As a result of the determination, when the rapid deceleration occurs in the saddle riding type vehicle 1 or when the operation at the high vehicle speed of the ABS occurs, the emergency braking signal generation output determination unit 30e indicates that the saddle riding type vehicle 1 is in the emergency braking state. It is determined that an emergency braking signal indicating that this is to be generated and output, and an emergency braking signal is output. On the other hand, if the result of the determination is that either a rapid deceleration has not occurred in the saddle riding type vehicle 1 or an operation at high vehicle speed of the ABS has not occurred, an emergency braking signal is generated. The output determination unit 30e does not determine that the emergency braking signal indicating that the saddle riding type vehicle 1 is in the emergency braking state should be generated and output it, and correspondingly outputs the emergency braking signal. Absent. Note that the emergency braking signal indicates that a rapid deceleration has occurred in the straddle-type vehicle 1 or that it has been determined that an ABS operation has occurred at a high vehicle speed. As long as it presents information indicating that it is determined to be in a state, it may be in the form of code information such as a flag or in the form of an electrical signal such as a voltage signal. Further, the emergency braking signal may be generated by a generating device outside the control device 30 and output to the control device 30 in addition to the signal generated by the functional block in the control device 30.

  In the process P5, the vehicle speed calculation unit 30a calculates the vehicle speed of the saddle riding type vehicle 1 based on the electrical signal output from the vehicle speed sensor 33 during or before the execution of this process, and the stop intention determination unit 30d determines whether or not the driver intends to stop in the process P3 before or after the execution of this process, and the emergency braking signal generation output determination unit 30e performs the process. Or, before that, since it is determined whether or not an emergency braking signal should be generated and output in the process P4, the emergency braking display permission determination unit 30g calculates the saddle type calculated by the vehicle speed calculation unit 30a. Whether or not the vehicle speed of the saddle-ride type vehicle 1 is equal to or higher than a predetermined vehicle speed (typically set equal to the predetermined vehicle speed in the process P2 and, for example, 50 km / h) based on data indicating the vehicle speed of the vehicle 1 Based on the data indicating whether or not there is a driver's intention to stop obtained in the process P3, whether or not there is a driver's intention to stop, and the emergency braking generated and output in the process P4 It is determined whether or not a signal is input. As a result of the determination, if it is determined that the vehicle speed of the saddle riding type vehicle 1 is equal to or higher than the predetermined vehicle speed, the driver intends to stop, and an emergency braking signal is input, the emergency braking display permission determination unit 30g Then, it is determined to permit the blinking operation of the emergency braking indicator lamp 4a. On the other hand, as a result of the determination, when the vehicle speed of the saddle riding type vehicle 1 does not exceed the predetermined vehicle speed, the driver does not intend to stop, and the emergency braking signal is not input, The emergency braking display permission determination unit 30g does not determine that the flashing operation of the emergency braking display lamp 4a is permitted. Here, in the processing of the process P3, it is determined that the driver intends to stop, because the braking operation of the FR brake 19 is performed instead of the braking operation of only the RR brake 20, and therefore the process P3 If it is determined that the operation of only the RR brake 20 has been performed in this process, the emergency braking display permission determination unit 30g can be said to prohibit the flashing operation of the emergency braking display lamp 4a without permitting it.

  In the process P6, the vehicle speed calculation unit 30a calculates the vehicle speed of the straddle-type vehicle 1 based on the electrical signal output from the vehicle speed sensor 33 during or before the execution of this process. The speed calculation unit 30b calculates the deceleration of the saddle riding type vehicle 1 from the change in the vehicle speed of the saddle riding type vehicle 1 based on the electrical signal output from the vehicle speed sensor 33 when or before executing this process. Therefore, the blinking cycle calculation unit 30h indicates the vehicle speed calculated by the vehicle speed calculation unit 30a from the table data indicating the relationship between the vehicle speed or deceleration of the saddle riding type vehicle 1 and the blinking cycle of the emergency braking indicator lamp 4a. By reading the blinking cycle of the emergency braking indicator lamp 4a corresponding to the deceleration in the data indicating the vehicle speed or deceleration calculated by the data in the data, the blinking cycle of the emergency brake indicator lamp 4a is read. It is calculated. From the viewpoint of improving the recognizability of the display content of the emergency brake indicator lamp 4a, when the deceleration of the saddle riding type vehicle 1 is large or the vehicle speed is high, the flashing cycle of the emergency brake indicator lamp 4a is shortened to When the deceleration of the type vehicle 1 is large or the vehicle speed is slow, it is preferable to lengthen the blinking cycle of the emergency braking indicator lamp 4a. Further, the blinking cycle of the emergency braking indicator lamp 4a may be determined using both the deceleration and the vehicle speed of the saddle riding type vehicle 1 as parameters. At the same time, when the deceleration of the saddle riding type vehicle 1 is large or when the vehicle speed is high, the amount of lighting of the emergency brake indicator lamp 4a may be increased.

  In the process P7, the emergency braking display permission determination unit 30g determines whether or not to permit the flashing operation of the emergency brake indicator lamp 4a in the process P5 before or during the execution of this process. In addition, since the blinking cycle calculation unit 30h calculates the blinking cycle of the emergency braking indicator lamp 4a in the process P6 at or before the execution of this process, the emergency braking indicator light drive signal generation output unit 30i determines whether or not the flashing operation of the emergency brake indicator lamp 4a is permitted based on data indicating whether or not the flashing operation of the emergency brake indicator lamp 4a obtained in the process P5 is permitted. . When the flashing operation of the emergency brake indicator lamp 4a is permitted as a result of the determination, the emergency brake indicator lamp drive signal generation output unit 30i performs the flashing based on the data indicating the flashing cycle calculated in the process P6. A drive signal for blinking the emergency brake indicator lamp 4a according to the cycle is generated. On the other hand, when the flashing operation of the emergency brake indicator lamp 4a is not permitted as a result of the determination, the emergency brake indicator lamp drive signal generation output unit 30i does not generate a drive signal for flashing the emergency brake indicator lamp 4a.

  Then, in response to the generation of the drive signal for blinking the emergency brake indicator lamp 4a in the process P7, the emergency brake indicator lamp drive signal generation output unit 30i outputs the drive signal applied to the emergency brake indicator lamp 4a. Is output, the emergency braking indicator lamp 4a enters a lighting state that blinks in the blinking cycle calculated in the process P6.

  As is apparent from the above description, the emergency braking indicator light control device 30 for the saddle-ride type vehicle in the present embodiment brakes the front wheel 2 via the front wheel operation member 12 and the rear wheel operation member 18. Applied to a straddle-type vehicle 1 having a two-system two-operation brake system capable of braking the rear wheel 3 and an emergency brake indicator light 4a. When the vehicle speed is equal to or higher than a predetermined vehicle speed, an emergency braking signal indicating that the saddle riding type vehicle 1 is in an emergency braking state is input, and a braking operation is performed on the front wheel 2 via the front wheel operation member 12, Since the emergency brake indicator lamp 4a blinks, in the saddle riding type vehicle 1 such as a motorcycle in which the brake system for braking the front wheel 2 and the rear wheel 3 is a two-system two-operation type, the following vehicle is in an emergency braking state. Announcing something quickly and clearly It can be.

  Further, in the control device 30 for the emergency braking indicator lamp of the saddle riding type vehicle in the present embodiment, the emergency braking indicator lamp 4a blinks when only the braking operation is performed on the rear wheel 3 via the rear wheel operation member 18. Therefore, unnecessary flashing of the emergency brake indicator lamp 4a can be suppressed.

  Further, in the emergency braking indicator lamp control device 30 for the saddle riding type vehicle in the present embodiment, the blinking cycle for blinking the emergency braking indication lamp 4a is calculated according to the deceleration or the vehicle speed of the saddle riding type vehicle 1. Therefore, it is possible to clearly blink (improve visibility) with a limited display area of the emergency braking indicator lamp 4a.

  In the control device 30 for the emergency braking indicator light of the saddle riding type vehicle in the present embodiment, the emergency braking signal indicates that the deceleration of the saddle riding type vehicle 1 is equal to or higher than a predetermined deceleration, or the vehicle speed is equal to or higher than a predetermined vehicle speed. In addition, since it is generated when the ABS is in operation, the saddle riding type vehicle 1 suddenly brakes the state in which the ABS is operating at a high vehicle speed even when the ABS is mounted. The emergency braking indicator lamp 4a can be controlled with the same handling as in the state.

  It should be noted that the present invention is not limited to the above-described embodiments in terms of the type, arrangement, number, etc. of the constituent elements, and departs from the gist of the invention, such as appropriately replacing such constituent elements with those having the same operational effects. Of course, it can be appropriately changed within the range not to be.
