DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention performs signal processing of a traveling pulse generated by a traveling sensor and having a frequency corresponding to the number of rotations of a tire to execute a traveling state such as a traveling distance or a vehicle speed of a vehicle. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for detecting a traveling state of a vehicle, wherein the traveling state of the vehicle can be detected by correction even if a tire diameter or a traveling sensor of the vehicle changes.

[Conventional technology]

The vehicle travel detection device is for detecting a vehicle travel state such as a travel distance or a vehicle speed of a vehicle such as an automobile based on a travel pulse generated by a travel sensor according to travel of the vehicle. A structure as shown in FIG. 7 applied to a vehicle indicating instrument such as a speedometer is generally used.

In FIG. 1, reference numeral 1 denotes a travel sensor.
Is constituted by a gearbox 1a for extracting rotational power from a transmission (not shown), and a rotation detection sensor 1b connected to the transmission via the gearbox 1a to receive rotational power. The rotational speed of the transmission, that is, the rotational speed of the tire 2, Generates a running pulse having a frequency corresponding to. The running pulse generated by the running sensor 1 is supplied to the indicating instrument 3.

The indicating instrument 3 has a microcomputer (CPU) 31 that operates according to a predetermined control program.
A signal processing unit 31 performs signal processing on the running pulse input from the running sensor 1 to perform a running distance calculation, a speed calculation, and the like. The CPU 31 has a built-in ROM 31a which is a read-only memory storing the above-mentioned control programs and the like, and a RAM 31b which is a readable and writable memory used as a work area. The indicating instrument 3 also has a display 32 for displaying a traveling distance and a speed based on a signal processing result by the CPU 31. The display 32 can be configured by, for example, a counter driven by a stepper motor in the case of displaying the traveling distance, or by a cross-coil indicating instrument in the case of displaying the speed.

The indicating instrument 3 is generally configured such that when the vehicle travels, for example, 1 km, the rotation detection sensor 1b is rotationally driven a predetermined number of times, for example, 637 times. Therefore, when a rotation detection sensor that generates eight traveling pulses per rotation is used, 1km is input by inputting 5096 traveling pulses.
You can recognize that you have run. Then, the vehicle speed can be measured by counting the number of traveling pulses per unit time of 5096 traveling pulses input during traveling the predetermined distance of 1 km, or by measuring the pulse period. Therefore, various data corresponding to the number of traveling pulses generated by the traveling sensor 1 during traveling for a predetermined distance, for example, 1 km, are stored in advance in the ROM 31a as reference data, and the reference data and the traveling pulse from the traveling sensor 1 are stored. Based on the above, signal processing is performed to determine the traveling distance and the vehicle speed by calculation.

However, the data stored in the ROM 31a depends on the diameter of the tire 2, the gear ratio of the gearbox 1a of the traveling sensor 1, and the structure of the rotation detection sensor 1b (the number of pulses per rotation of the sensor). If the diameter 2 and the travel sensor 1 are different, a correct travel distance cannot be obtained.

Therefore, as an example of a device that can respond to this, a setting switch 4 as shown by a dotted line in the figure is connected to the CPU 31 and the diameter of the tire 2 that is known to be used in advance and the traveling sensor 1 are set in advance. The formed plurality of correction data is stored in the ROM 41a, one of the correction data is selected by the setting switch 4, and the reference data and the vehicle speed set for obtaining the correction distance based on the selected correction data are set. A device which can cope with the combined use of a plurality of tires 2 and the travel sensor 1 by correcting the reference data set for obtaining or correcting the result processed by the reference data with the correction data is used. It is becoming.

As another example of a device that can cope with this, as shown in FIG.
1 and a pulse conversion circuit 5 having
A plurality of correction data formed in advance in correspondence with the diameter of the tire 2 and the travel sensor 1 that are known to be used in advance are stored in the ROM 51a provided in the 51,
One of these correction data is selected by the setting switch 52, and the frequency of the travel pulse from the travel sensor 1 is converted based on the selected correction data. A device adapted for use has been proposed, for example, in Japanese Utility Model Application No. Sho 62-152243.

In any of the above-described cases, the correct travel distance and vehicle speed are obtained by performing a predetermined correction based on the correction data selected by the setting switch 4 or 52.

As a specific example, a standard running sensor 1 that generates 8 pulses per tire rotation, and a standard tire 2 with a predetermined tire diameter
When the vehicle travels 1 km with 637 revolutions of the tire 2, the traveling sensor 1 generates 5096 traveling pulses by traveling 1 km, and the number 5096 of the traveling pulses is used as a reference for all signal processing. Become.

Assuming that the number of pulses generated by the traveling sensor 1 when traveling 1 km in two different combinations of the diameter of the tire 2 and the traveling sensor 1 are 2000 pulses and 7000 pulses, respectively, 5096/2000 = 2.548, 5096, respectively. /7000=0.7
By storing 28 in advance in the ROM 31a as the correction data, one of the two correction data can be selected and set by the ON / OFF operation of the setting switch 4 so as to correspond to any of both combinations. become able to.

The travel distance and the vehicle speed can be obtained by subjecting the travel pulse to signal processing using data obtained by dividing the reference data stored in the ROM 31a by these correction data as new reference data. Thus, in addition to the combination of the standard tire 2 and the standard traveling sensor 1, the traveling distance can be obtained for three different combinations of two different combinations.

In the specific example, the correction data in the case of two different combinations are shown, but the correction data can be stored in advance for the expected number of combinations of the tire 2 and the travel sensor 1.

[Problems to be solved by the invention]

In the conventional correction method and device of the vehicle running detection device, only the correction data of the combination of the tire and the running sensor that will be used is set. Therefore, it is necessary to newly create a ROM storing correction data corresponding to the above, and there is a problem that the versatility is poor and the cost is high.

Accordingly, the present invention has been made in view of the above-described conventional problems, and has been made to be able to cope with an arbitrary combination falling within a range of a combination of a maximum width predicted in advance, thereby improving versatility and reducing costs.

Are denoted by the same reference numerals.

The vehicle travel detection device shown in FIG. 2 stores correction data determined as described later with reference to FIG. 4 in a ROM 31a serving as a storage unit A of a CPU 31 serving as a signal processing unit C, and stores the correction data in the ROM 31a.

In the vehicle traveling detection device shown in FIG. 3, correction data determined as described later with reference to FIG. 4 is stored in a ROM 51a serving as a storage unit A of a CPU 51 serving as a signal processing unit C, and stored in the ROM 51a. A setting switch 52 serving as B as setting means connected to the CPU 51 for selecting one of the stored correction data is constituted by eight dip switches, and each of the eight dip switches is turned on and off by a binary. 1, binary 0 by off
, Respectively, so that an 8-bit binary number can be set.

FIG. 4 is a diagram for explaining an example of correction data stored in the ROMs 31a and 51a. Specifically, when the number of traveling pulses generated by the predetermined traveling sensor when the vehicle travels 1 km on the predetermined tire is 5096, the vehicle and the tire actually mounted on the vehicle and the traveling sensor The method of forming correction data that can correspond to a combination of a tire of any diameter and a travel sensor whose minimum number of travel pulses generated by the travel sensor when traveling 1 km is 2000 and the maximum number is 10000 Show. Since the 8-bit setting switch 4 can be set in 256 ways, (10000
−2000) / 256 ≒ 32, where 2000 to 10000 are divided into 32, and the correction rate obtained by dividing 5096 by this reference value using the simple average value of each division as a reference value is used as correction data.

Although only 220 types of correction data are shown in the illustrated table, the correction data formed as described above is previously stored and held in the ROMs 31a and 51a.

The above-described correction data is stored in the ROMs 31a and 51a, and the number of traveling pulses generated by the traveling sensor when the vehicle travels 1 km is between 2000 and less than 2032. When a combination is used, the correction data (correction rate 2.5278) is selected by setting 1 (00000000 in binary) with the setting switches 4 and 52. The selected correction rate of 2.5278 converts the frequency of the traveling pulse from the traveling sensor to correct the number of pulses per unit time and the pulse period to correct the reference pulse number data input when traveling 1 km. In addition to this, it is used for correcting the traveling distance and the vehicle speed obtained before the correction.

In the case of a combination of a tire and a travel sensor that falls within the width 32 between 2032 and less than 2064, the correction data (correction rate 2.4883) is selected by setting 2 (00000001 in binary) with the setting switches 4 and 52.

By increasing the number of bits of the setting switches 4 and 52 to reduce the width of each section, the maximum error rate, that is, (maximum value−minimum value of each section) / reference value can be further reduced. become.

FIG. 5 is a diagram for explaining another example of the correction data stored in the ROMs 31a and 51a. The table in FIG. 5 also shows that the minimum number of traveling pulses generated by the traveling sensor when the vehicle travels 1 km is 2,000 and the maximum number is 10,000, based on the tires and traveling sensors actually mounted on the vehicle. The method of forming the correction data corresponding to the combination of the tire and the travel sensor of FIG. Since the 8-bit setting switch 4 allows 256 settings, the range from 2000 to 10000 is divided by an equal ratio of 1.00065, and the value obtained by rounding the simple average value of each division to 5096 is used as a reference value. The correction rate obtained by dividing by is used as correction data. For example 2000
The range from 2013 to 2013, which is obtained by adding (2000 × 1.0065 ≒) 13, is divided into one. Although only 235 types of correction data are shown in the illustrated table, the correction data formed as described above is stored and held in the ROMs 31a and 51a in advance.

The above-described correction data is stored in the ROMs 31a and 51a, and the number of traveling pulses generated by the traveling sensor when the vehicle travels 1 km is between 2000 and less than 2013. When a combination is used, the correction data (correction rate 2.5397) is selected by setting 1 (00000000 in binary) with the setting switches 4 and 52. The selected correction rate of 2.5397 converts the frequency of the traveling pulse from the traveling sensor to correct the number of pulses per unit time and the pulse period in order to correct the reference pulse number data input when traveling 1 km. In addition to this, it is used for correcting the traveling distance and the vehicle speed obtained before the correction.

Further, in the case of a combination of a tire and a traveling sensor which falls within the width 13 between 2013 and less than 2026, the correction data (correction rate 2.5233) can be selected by setting 2 (00000001 in binary) with the setting switches 4 and 52. I just need. Hereinafter, in the same manner, 1 km depending on a combination of an arbitrary tire and a travel sensor.

Any combination of tires and travel sensors from 00 to a maximum of 10,000 can be handled.

Of course, in the example shown in FIG.
By decreasing the value of the equality ratio by increasing the number of bits, the maximum error rate can be further reduced.

In the above-described embodiment, the tire diameter and the number of traveling pulses per rotation of the traveling sensor (the gear ratio of the traveling sensor × the number of rotations per rotation of the rotation detecting sensor) are set for setting the setting switch for an arbitrary tire and traveling sensor. Number of running pulses)
And the number of pulses obtained by performing a calculation manually is determined on the basis of the above, and the set value by the setting switch is determined with reference to a symmetric table as shown in FIG. 4 and FIG. However, the setting value of the setting switch is automatically obtained by inputting the number of running pulses for one rotation of the rotation detection sensor, the gear ratio G, and the tire diameter r by causing the personal computer to execute the flowchart of FIG. can do.

That is, the number of running pulses per rotation of the rotation detection sensor S (= 8) is input in step S1 using the keyboard of the personal computer, the tire radius r is input in the next step S2, and the gear is input in the next step S3. After inputting the ratio G, the personal computer is 1km in step S4.
Assuming that the rotation speed of the rotation detection sensor during traveling is 637, the traveling pulse number Psp = 637 × S (= 5096) generated during traveling for 1 km is obtained by calculation. Then, the process proceeds to step S5, in which the running sensor having the tire diameter r and the running ratio of the gear ratio G and the number of pulses S is mounted and the running sensor generates a running pulse number Pcar = 1000 / 2πr × when the vehicle runs 1 km. G × S is calculated and obtained. Thereafter, the process proceeds to step S6, and the correction rate R = Ps
After calculating and calculating p / Pcar, the process proceeds to step S7, where it is set by the setting switch with reference to a data table previously stored in the personal computer, such as the table shown in FIGS. 4 and 5, 2 Determine the decimal value. In the last step S8, the correction factor R obtained in step S6 and the binary value set by the setting switch determined in step S7 are displayed on the CRT screen of the personal computer, and a series of work is completed.
In this way, desired correction data can be selected by setting the setting switch based on the binary value displayed on the CRT screen without performing manual calculation.

(Effect)

As described above, according to the present invention, the number of pulses generated per rotation while a vehicle equipped with a tire having an arbitrary diameter travels a predetermined distance is the minimum value of the number of traveling pulses generated by an arbitrary traveling sensor. A large number of correction data consisting of correction data corresponding to each section obtained by dividing the range from to a maximum value into a large number with a predetermined width is stored in advance, and the vehicle travels a predetermined distance with a combination of the actually mounted tire and the travel sensor. By selecting a section in which the number of traveling pulses generated by the traveling sensor enters during the setting, the correction data corresponding to the section is selected, and the number of the sections falling between the minimum value and the maximum value by traveling a predetermined distance is selected. A tire with an arbitrary diameter that generates a running pulse and the number of generated pulses per revolution can correspond to a combination with an optional running sensor, so that versatility is improved and cost is reduced. It is possible.

In particular, since the above-mentioned predetermined width is set so that the ratio to the number of running pulses is equal in each section, the correction rate per pulse can be made substantially equal in the entire range from the minimum value to the maximum value. Thus, almost the same detection result as that of the reference data can be obtained.
