Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention sounds an alarm buzzer to alert you when the vehicle speed reaches a preset alarm speed. This invention relates to a speed warning device for a vehicle that emits a sound.

0002

[Conventional technology]

Conventionally, with this type of device, the driver manually operated the alarm speed setting knob to set the alarm speed. By setting the speed to an arbitrary value, the vehicle speed will exceed the set alarm speed. A buzzer will sound to warn the driver that the vehicle speed has exceeded the warning speed. There is something that I have done. However, with this device, once the knob is turned off, the alarm Since it is possible to prevent the alarm from being emitted, some drivers may choose to turn it off as it may be annoying. There were times when I would drive around.

0003 For this reason, in some cases, such as transportation companies that manage a large number of vehicles, each driver is given a The above-mentioned devices are not very useful if you want to ensure that the vehicle is not driven below the vehicle speed. Not worth it. Therefore, we decided to prevent the driver from turning off the warning at 60km/h, for example. A device in which the reporting speed is fixedly set has been considered.

0004

[Problem that the idea aims to solve]

This device can reliably emit a warning sound when the vehicle speed exceeds 60km/h. There is no problem when driving on general roads, but when driving on expressways with different speed limits. When driving on such roads, the warning sound continues to sound, causing discomfort to the driver. There was a problem.

[0005] Therefore, in view of the above-mentioned conventional problems, the present invention has been developed to reduce the fixed alarm speed. Even if the speed limit is exceeded, if you drive on a road such as an expressway with a different speed limit, you will not be able to drive. It is an object of the present invention to provide a speed warning device for a vehicle that does not dynamically generate a warning sound. This is an issue.

[0006]

[Means to solve the problem]

The speed warning device for vehicles developed according to the present invention in order to solve the above problems is shown in Figure 1. As shown in the basic configuration diagram, the alarm buzzer 6 will sound when the vehicle speed reaches the preset alarm speed. In a vehicle speed warning device that sounds an alarm sound, the vehicle speed is Start timing when the speed exceeds the alarm speed plus a predetermined value, A clock means 22e that measures the time that this state continues, and a clock means 22e that measures the time that this state continues. When the measured time exceeds a predetermined time, the alarm buzzer 6 sounds. It is characterized by comprising a ringing control means 23 for interrupting the operation.

[0007] The vehicle speed warning device controls the sound when the vehicle speed becomes lower than a predetermined speed. a return control means for restarting the sounding operation of the alarm buzzer 6 that was interrupted by the means 23; It is characterized by further comprising a stage 24.

[0008]

[Effect]

In the configuration shown in Fig. 1 above, the vehicle speed is the speed obtained by adding a predetermined value to the warning speed. When this happens, the clocking means 22e starts counting the time and how long this state continues. is measured, and when the time measured by the timer 22e exceeds a predetermined time, When this happens, the sound control means 23 interrupts the sounding operation of the alarm buzzer 6. Eliminates the generation of harsh warning sounds on expressways where vehicles travel at speeds higher than the warning speed. can do.

[0009] Further, when the vehicle speed becomes less than a predetermined speed, for example, 0 km/h, the return control means 2 4 restarts the sounding operation of the alarm buzzer 6 that was interrupted by the sounding control means 23. This eliminates the hassle of recovery operations.

【Example】

Hereinafter, embodiments of the present invention will be described based on the drawings. Figure 2 shows digital operation for vehicles. An example of a speed warning device for a vehicle according to the present invention incorporated into a data recording device is shown. vinegar. In the figure, the vehicle digital operation data recording device is connected to the vehicle's transmitter. The vehicle is connected to the vehicle by a connecting means (not shown), and the vehicle speed changes as the vehicle travels. A running sensor 1 that generates a running signal with a frequency of It has a microcomputer (CPU) 2 that samples and inputs signals. . The CPU 2 has a ROM 21 that stores control programs, etc., and stores various data. RA that has a data area to store data, a work area used for CPU2 operation, etc. It has a built-in M22.

[0011] The CPU 2 operates according to the control program in the ROM 21 and controls the running sensor 1. calculates the instantaneous speed and travel distance based on the driving signal input from the The instantaneous speed and distance traveled determined by this calculation are recorded as digital data. It performs work such as recording on the IC memory card 3 as a medium. CPU2 has The card connector 4 into which the IC memory card 3 is inserted and removed is connected. The card settings recorded on the IC memory card 3 inserted into the controller 4 can be The digital operation data is read into the IC memory card 3. data may be written. In addition, CPU2 generates data representing real time. A clock 5 is activated, and a warning sound is emitted to warn that the vehicle speed exceeds the warning speed. A buzzer 6 is also connected.

As shown in FIG. 3, the IC memory card 3 includes a card ID area 31 for writing a card ID for identifying the IC memory card 3, and a sampling timing area 31 written by an operation data analysis device to be described later. A setup data area 32 that stores setup data such as a sample time for determining the signal cycle, a warning speed V _K and a predetermined value V _O related thereto, and an operation data area 33 for writing collected vehicle speed and mileage data. In the operation data area 33, operation ID data for indicating the division of operation data of each operation is also written.

[0013] On the other hand, as shown in FIG. 4, the RAM 22 in the CPU 2 has an IC memory card 3. Area 22a where setup data read from is written, initial flag F Area 22b for setting 1, area 22c for setting cancel flag F2, Area 22d for setting broadcast flag F3, configuring 10 second timer counter TC. Areas 22e and the like are formed.

[0014] In the above configuration, the CPU 2 receives running signals according to the sampling timing signal. The signal is sampled, and calculations are performed based on the sampled running signal. The IC memory card inserted into the card connector 4 calculates the hourly speed and mileage. The operation data to be written to the card 3 is formed. This operation data is immediately after the start of operation. If it is data, the CPU 2 uses the operation ID to identify the operation. Data such as row start time is also written.

[0015] Furthermore, when the instantaneous speed obtained by the above calculation is equal to or higher than the warning speed _VK stored in the setup data area 22a of the RAM 22 as setup data, the buzzer 6 is sounded to indicate that the vehicle speed is equal to or higher than the warning speed. warn you of this. Note that if the vehicle speed is faster than the warning speed V _K by a predetermined value V _{O or} more, and the vehicle continues to run at this speed for a certain period of time, for example, 10 seconds or more, it is determined that the vehicle has entered the expressway from a general road, and the vehicle speed is set as the alarm. To prevent a warning sound from being annoying to the driver's ears by interrupting the sounding of a buzzer 6 even when the speed is higher than the speed limit.

[0016] Note that the IC memory card 3 is The operation data written to and collected by the personal computer is stored in the personal computer as shown in Figure 5. Insert the IC memory card 3 into the RW 11 connected to the analysis device 10 consisting of a The information is read by the analysis device 10 and analyzed.

[0017] The analysis device 10 displays a menu when the FD 12 is installed in the FD driver 10a. is performed on the CRT 10b. This menu includes card initialization processing, termination processing, FD There are reading processing and card reading processing, and when initialization processing is selected, RW11 The installed IC memory card 3 is initialized, and at this time the IC memory card Write the setup data in the setup data area of 3. In addition, 10c Use the keyboard to command the operation of the analysis device 10 and create setup data. It is used when

[0018] The above is a brief explanation of the operation of the vehicle digital operation data recording device and analysis device 10. However, the details will be explained below with reference to the flowcharts of FIGS. 6 to 8.

[0019] Figure 6 shows how the CPU 2 of the vehicle digital operation data recording device operates according to the control program. This is a flowchart showing the work to be executed by the CPU 2 when the power is turned on. The operation is started, initialization is performed in the first step S1, and the first The lag F1, cancel flag F2, and warning flag F3 are set to 0.

[0020] Next, the process advances to step S2, where the ignition (IG) switch of the vehicle is turned on. The IG switch is determined based on a signal from an IG detection circuit (not shown). When the switch is off, the CPU 2 is put into a sleep state in step S3, In the next step S4, clock processing is performed. After that, in step S5, I Determine whether the G switch is turned on or not, and continue in step S until this determination becomes YES. Repeat steps 3 to S5.

[0021] If the determination in step S5 is YES, the process returns to step S2, and step The process advances to step S6 via S2. In step S6, various sensors (not shown) are information to determine whether the IC memory card is in a recordable state depending on the Enter information. After that, clock processing is performed in step S7, and then step S8 The process proceeds to step S6, where the IC memory card is loaded based on the information input in step S6 above. Determine whether or not the card is in a recordable state.

[0022] If the determination in step S8 is YES, the process advances to step S9, where the first Determine whether the lag is 1. If the determination in step S9 is NO, the step Proceed to step S10, where the setup data is read from the IC memory card 3. , this read setup data is stored in area 22a in RAM 22. Next, the process advances to step S11, where the start time and ID are entered in the IC memory card 3. Write to row data area 33.

[0023] After that, the process proceeds to step S12, where the initial flag F is set to 1 in step S12. Ru. Next, the process advances to step S13, where the speed data is compressed and recorded. In the subsequent step S14, the mileage is recorded, and then in the step S14, the mileage is recorded. Return to 2.

[0024] In step S8 above, it is determined that the IC memory card is not in a recordable state. When it is determined, the process advances to step S16, where it is determined whether the first flag F1 is 1 or not. If the determination is NO, the process returns to step S2. Step S16 If the determination is YES, the initial flag F1 is set to 0 in step S17, and the After that, proceed to step S18 to perform the IC memory card termination process, and then proceed to step S18. Return to 2.

[0025] In addition, in the process of the above processing, the alarm processing is performed by a timer interrupt every 0.5 seconds. S20 is performed. In detail, as shown in the flowchart of Figure 7, first After calculating the speed S in step S20a, the process proceeds to step S20b, where Then, it is determined whether the speed S calculated in step S20a is 0 or not, that is, the vehicle has stopped. Determine whether or not the

[0026] When the vehicle is stopped and the determination in step S20b is YES, step S Proceed to step S20c to set the cancel flag F2 to 0, and then proceed to step S20d to set the cancel flag F2 to 0. After setting the flag F3 to 0, the process proceeds to step S20e, where the timer counter TC is After setting a predetermined value corresponding to 10 seconds, the process returns to the flowchart of FIG.

[0027] When the vehicle is running and the determination in step S20b is NO, the process proceeds to step S20f, where it is determined whether the cancel flag F2 is 1, and when the determination in step S20f is NO, the process proceeds to step S20g. It is determined whether the warning flag F3 is 1 or not. If the determination in step S20g is NO, the process proceeds to step S20h, where it is determined whether the speed S calculated in step S20a is equal to or higher than the alarm speed _VK , and if this determination is NO, the process proceeds to step S20e as shown in FIG. Return to flowchart.

When the speed S of the vehicle becomes equal to or higher than the warning speed V _K and the determination in step S20h becomes YES, the process proceeds to step S20i, where the warning flag F3 is set to 1, and then the process proceeds to step S20j, where the buzzer 6 is turned on. After that, an alarm sound indicating that the alarm speed has been exceeded is generated, and then the process returns to the flowchart of FIG.

[0029] After that, through steps S20a, S20b, and S20f, the process reaches step S20g. Then, the determination in step S20g at this time is YES, and the process proceeds to step S20k. , and here the speed S is the alarm speed V_KThis step S If the determination of 20k is YES, the process advances to step S20l and the speed S is set to the alarm speed V. _K to a predetermined value V_ODetermine whether the speed is greater than or equal to the sum of In step S20m, the timer counter TC is set to a predetermined value, and then The process returns to the flowchart of FIG. 6 through step S20j, and the buzzer 6 continues to sound. .

[0030]When the determination in step S20l is YES, that is, when the speed S is equal to or higher than V _K +V _O , the process proceeds to step S20n, where the content of the timer counter TC is decremented, ie, -1, and then the process proceeds to step S20o, where the timer counter is incremented. Determine whether the content of the TC is 0 or not. If the determination in step S20o is NO, the process returns to the flowchart of FIG. 6 via step S20j, and the buzzer 6 continues to sound.

[0031] While the vehicle is running at a speed S greater than or equal to V _K +V _O , the decrement is performed sequentially in step S20n, but before the vehicle continues for 10 seconds, the speed becomes less than or equal to V _K +V _O , and the determination in step S20l is made. Since the answer is NO and the process returns to the flowchart shown in the figure through steps S20m and S20j, the buzzer 6 continues to sound, but the predetermined value is again set in the timer counter TC. Further, when the speed S decreases below the alarm speed _VK , a predetermined value is set in the timer counter TC in step S20p, and the alarm flag F3 is set to 0 in the subsequent step S20q, and then the process returns to the flowchart of FIG. will stop ringing.

[0032] When the speed S of the vehicle is equal to or higher than V _K +V _O for 10 seconds or more, the determination in step S20o becomes YES and the process proceeds to step S20r, where the cancel flag F2 is set to 1, and in the subsequent step S20s, the warning flag is set. After setting F3 to 0, return to the flowchart of FIG. 6. Therefore, since the determination in step S20f becomes YES from now on, the vehicle can run without sounding the buzzer 6 even if the speed S is equal to or higher than the alarm speed V _K until the vehicle stops and the determination in step S20b becomes YES. become able to.
