Description

  The present invention relates to a tire ID automatic registration system that automatically registers a tire ID of each tire communication device in a vehicle body.

  In recent years, vehicles tend to be equipped with a tire pressure monitoring system that monitors the tire pressure of each tire during traveling for the purpose of ensuring the safety of the traveling vehicle. In this system, a tire communicator is attached to each tire, the tire air pressure is detected by the tire communicator, and the detected value is wirelessly transmitted to the vehicle body as a tire air pressure signal. The vehicle body receives the tire air pressure signal by the receiver, grasps the tire air pressure, and if there is a tire whose tire air pressure is less than the low pressure threshold, notifies the driver of that fact.

  In the tire pressure monitoring system, it is necessary to know which position of the tire is a low-pressure tire. Therefore, the tire ID of each tire communication device is registered in the receiver in a state where the tire position is associated. Is done. In this case, the tire pressure monitoring system has a tire ID automatic registration function (auto location function) as an operation for periodically checking the tire position while the vehicle is running. For example, as this function, a technique is disclosed in which an initiator is used and the vehicle is determined based on the difference in received signal intensity of radio waves transmitted from the initiator (see Patent Document 1).

JP 2009-226966 A

  However, Patent Document 1 can automatically register a tire ID in a receiver. However, since the technique uses an initiator, there is a problem that the entire configuration becomes complicated. Moreover, since patent document 1 performs ID registration when a trigger switch is operated, if the vehicle is running side by side at this time, the tire ID transmitted from the tire communication device of the parallel running vehicle is assigned to the own vehicle. There are concerns about being registered. If this happens, the tire ID of the other vehicle will be registered in the own vehicle, and there was a need for technological development capable of accurately registering the tire ID.

  An object of the present invention is to provide a tire ID automatic registration system capable of simplifying the system configuration and ensuring the registration accuracy of the tire ID.

In order to solve the above problems, in the present invention, a tire pressure signal transmitted from a tire communication device attached to each tire is received by a receiver of the vehicle body, and the pressure of each tire is determined based on the tire pressure signal. A tire ID automatic registration system that is used in a tire pressure monitoring system to be monitored and automatically registers a tire ID of the tire communication device in the vehicle body, and detects whether or not the vehicle is in a running state. In the temporary registration mode, if the vehicle is running, the tire ID wirelessly transmitted from the tire communication device is received, and temporary registration means for temporarily registering the tire ID in the receiver is temporarily registered. A book that determines which of the tire IDs is that of the own vehicle and that is registered in the receiver as the tire ID of the own vehicle, based on the determination result And recording means, the post-registration, by checking the reception status of the present registered the tire ID, and the gist that a false registration confirmation means for confirming the presence or absence of a mis-registered tire ID.

  According to the configuration of the present invention, in the temporary registration mode, when the receiver receives the tire ID from the tire communication device, the tire ID is temporarily registered if the vehicle is running. During the temporary registration mode, the tire ID is temporarily registered each time the receiver receives the tire ID, and the tire ID is collected. Then, after the provisional registration mode is finished, the ID that is determined to be that of the own vehicle among the temporarily registered tire IDs is finally registered in the receiver as the tire ID of the own vehicle. For this reason, the tire ID can be automatically registered in the receiver without using other components (for example, an initiator or the like), so that the tire ID automatic registration system can have a simple structure.

According to the configuration of this, since the judgment by the registration check unit erroneously the validity of the registration tire ID, misregistration can be detected tire ID. Therefore, an effect becomes high in ensuring the registration accuracy of the tire ID.

  In the present invention, a reception signal strength measuring unit that measures a received signal strength when the receiver receives the tire ID is provided, and the main registration unit has a high received signal strength among the temporarily registered tire IDs. The gist of this is that this is registered in the receiver as a tire ID of the own vehicle. According to this configuration, a temporary registration tire ID having a high received signal strength is registered as a tire ID of the own vehicle. Therefore, since the tire ID to be permanently registered is identified by a highly accurate method of confirming with the received signal strength, the effect of ensuring the registration accuracy of the tire ID is enhanced.

  In the present invention, the travel detection means detects whether or not the vehicle is in a travel state in which a vehicle speed is generated, and detects the rotation of the tire to detect the rotation of the vehicle from the rotation of the tire. Tire rotation detection means for detecting a running state, and the temporary registration means performs temporary registration when it is determined that the vehicle is running by both the vehicle travel detection means and the tire rotation detection means. The gist is to do it. According to this configuration, when both the vehicle travel detection unit and the tire rotation detection unit can detect that the vehicle travels, it is determined that the vehicle is traveling, so whether or not the vehicle is in a traveling state, It becomes possible to determine more accurately. Therefore, the effect of securing the accuracy of temporary registration of the tire ID is enhanced.

  According to the present invention, the system configuration can be simplified, and the registration accuracy of the tire ID can be ensured.

Hereinafter, an embodiment of a tire ID automatic registration system embodying the present invention will be described with reference to FIGS.
As shown in FIG. 1, the vehicle 1 is equipped with a tire pressure monitoring system (TPMS: Tire Pressure Monitoring System) 3 that monitors the tire pressure of each tire 2 (2a to 2d). The tire air pressure monitoring system 3 detects tire air pressure and the like by a tire communication device 4 (4a to 4d) attached to each tire 2a to 2d, and wirelessly transmits the detection result to the vehicle body 5 as a tire air pressure signal Stp. The vehicle body 5 confirms the tire air pressure from the tire air pressure signal Stp and notifies the driver of the result.

  The tire communication device 4 is provided with a communication device control circuit 6 that manages the tire communication device 4 in an integrated manner. In the memory 7 of the communication device control circuit 6, tire IDs are registered as unique IDs of the tires 2a to 2d. The tire communication device 4 is provided with a pressure sensor 8 that detects tire air pressure, a temperature sensor 9 that detects tire temperature, and an acceleration sensor 10 that detects rotation of the tire 2, and these are connected to the communication device control circuit 6. Yes. These sensors output detection signals to the communication device control circuit 6. The communication device control circuit 6 is connected to a transmitter 11 capable of transmitting UHF (Ultra High Frequency) band radio waves.

  The vehicle body 5 is provided with a receiver (hereinafter referred to as a TPMS receiver) 12 that monitors the air pressure of the tire 2 based on the tire air pressure signal Stp received from the tire communication device 4. The TPMS receiver 12 is provided with a tire air pressure monitoring ECU 13 that comprehensively manages the operation of the TPMS receiver 12. In the memory 14 of the tire pressure monitoring ECU 13, tire IDs of the tire communication devices 4a to 4d are registered in association with tire positions. The tire pressure monitoring ECU 13 is connected to a receiving unit 15 capable of receiving UHF radio waves. The receiving unit 15 includes an antenna 15a and a receiving circuit 15b that amplifies and demodulates received radio waves. For example, a display unit 16 installed on an in-vehicle instrument panel or the like is connected to the TPMS receiver 12.

  When the tire communication device 4 detects that the tire 2 has entered a rotating state (the vehicle 1 is in a traveling state) based on the acceleration signal output from the acceleration sensor 10, the tire communication device 4 starts transmitting the tire air pressure signal Stp. In addition to the tire ID, the tire air pressure signal Stp includes pressure data acquired from the pressure sensor 8, temperature data acquired from the temperature sensor 9, and the like. Each tire communication device 4 transmits a tire pressure signal Stp with a random time difference so that radio transmission does not overlap with other tire communication devices 4.

  The tire communication device 4 switches the transmission interval of the tire air pressure signal Stp based on the acceleration signal input from the acceleration sensor 10. For example, the tire communication device 4 transmits the tire air pressure signal Stp at an interval of 1 time / minute when the vehicle travels, and transmits the tire air pressure signal Stp at an interval of 1 time / 5 minutes when the vehicle stops.

  When the tire pressure monitoring ECU 13 receives the tire pressure signal Stp by the receiving unit 15, the tire pressure monitoring ECU 13 performs ID verification based on the tire ID in the tire pressure signal Stp. When the tire pressure monitoring ECU 13 confirms that the ID verification is established, the tire pressure monitoring ECU 13 checks the tire pressure by comparing the pressure data included in the same signal with the low pressure threshold, and if the tire pressure is less than the low pressure threshold, The tire position is displayed on the display unit 16, and a low pressure alarm is output.

  The tire pressure monitoring ECU 13 sets a low pressure threshold based on the detected temperature value (tire temperature) in the tire pressure signal Stp. This is because an optimum low pressure threshold is set according to the tire temperature because the tire air pressure naturally increases as the tire temperature increases.

  The tire pressure monitoring system 3 is provided with a tire ID automatic registration system 17 that automatically registers (re-registers) the tire ID of the tire communication device 4 in the vehicle body 5 during traveling, for example. The tire ID automatic registration system 17 is an auto-location function that is periodically executed in the vehicle 1 in order to confirm the validity of the tire ID registered in the vehicle body 5, and shifts to the tire ID registration mode at a predetermined time. The tire ID registration operation is executed. Further, the tire ID automatic registration system 17 of the present example can prevent the tire ID of the other vehicle from being erroneously registered in the own vehicle even if the other vehicle 1b is running around the own vehicle 1a.

  The communication device control circuit 6 is provided with a signal transmission control unit 18 that transmits a tire air pressure signal Stp when the tire rotates. When the tire communication device 4 transmits the tire pressure signal Stp to the vehicle body 5, the signal transmission control unit 18 causes the tire pressure signal Stp to include the tire rotation start information Drt for transmission. Therefore, the tire air pressure signal Stp is a signal having tire rotation start information Drt in addition to the tire ID. The tire rotation start information Drt is a signal transmitted for a predetermined time when the tire 2 starts to rotate, and is data for notifying the TPMS receiver 12 that the tire 2 is in a rotating state.

  The tire pressure monitoring ECU 13 is provided with a vehicle travel start detection unit 19 that detects whether or not the vehicle 1 has started traveling. The vehicle travel start detection unit 19 acquires vehicle speed information (vehicle speed data) from, for example, a meter ECU, and detects whether or not vehicle travel has started based on the vehicle speed information. Note that the vehicle travel start detection unit 19 constitutes a travel detection means (vehicle travel detection means).

  The tire pressure monitoring ECU 13 is provided with a tire rotation start detection unit 20 that detects whether or not the tire 2 has started rotating based on the tire rotation start information Drt received from the tire communication device 4. When the TPMS receiver 12 receives the tire pressure signal Stp from the tire communication device 4, the tire rotation start detection unit 20 determines whether the tire 2 has started to rotate based on the tire rotation start information Drt in the tire pressure signal Stp. To detect. The tire rotation start detection unit 20 constitutes a travel detection means (tire rotation detection means).

  The tire pressure monitoring ECU 13 is provided with a received signal strength measuring unit 21 that measures a received signal strength (RSSI) of a radio wave received by the TPMS receiver 12. When the TPMS receiver 12 receives the tire pressure signal Stp, the received signal strength measuring unit 21 measures the received signal strength at this time. The received signal strength measuring unit 21 corresponds to a received signal strength measuring unit.

  The tire pressure monitoring ECU 13 is provided with a tire ID temporary registration unit 22 that temporarily registers the tire ID received from the tire communication device 4 when the operation mode of the TPMS receiver 12 is the temporary registration mode. The tire ID temporary registration unit 22 receives the TPMS receiver 12 in the temporary registration mode for a certain time after the ignition switch of the vehicle 1 is turned on, and receives the tire ID only when the rotation start state of the tire 2 and the vehicle travel start state coincide with each other. Received and temporarily registered the tire ID. That is, the tire ID temporary registration unit 22 temporarily registers the tire ID only when it can be recognized from both the tire communication device 4 and the vehicle body 5 that the vehicle 1 is in the traveling state. The tire ID temporary registration unit 22 also registers the received signal strength when the tire ID is received when temporarily registering the tire ID. The tire ID storage area of the memory 14 has an area where, for example, eight or more tire IDs can be registered, assuming that there is a vehicle running side by side. The tire ID temporary registration unit 22 corresponds to temporary registration means.

  The tire pressure monitoring ECU 13 is provided with a tire ID main registration unit 23 for main registration of the temporarily registered tire ID. The tire ID main registering unit 23 performs main registration in the memory 14 as four tire IDs of the own vehicle 1a among the temporarily registered tire IDs. The tire ID main registration unit 23 corresponds to a main registration unit.

  The tire pressure monitoring ECU 13 is provided with an erroneous registration determination unit 24 that confirms the validity of the tire ID that has been registered. The erroneous registration determination unit 24 monitors the reception status of the registered tire ID after the main registration, and updates the tire ID of the own vehicle if the tire ID of the main registration can be received within a certain period. In addition, tire IDs that cannot be received for a certain period are processed as erroneous registration IDs, and tire IDs having the highest received signal strength among tire IDs that have not been temporarily registered are moved up to the main registration IDs and rewritten. The misregistration determination unit 24 periodically performs misregistration confirmation. The erroneous registration determination unit 24 corresponds to an erroneous registration confirmation unit.

  Next, operation | movement of the tire ID automatic registration system 17 of this example is demonstrated using FIG.2 and FIG.3. The ID registration operation by the tire ID automatic registration system 17 is executed every time an ignition switch (not shown) is turned on.

  In step 101, the tire ID temporary registration unit 22 determines whether or not the ignition switch of the vehicle body 5 is on. At this time, if the ignition switch is off, the process waits in step 101, and if the ignition switch is on, the process proceeds to step 102 in order to execute a temporary registration operation of the tire ID. Note that the ignition switch on refers to a state in which the power source of the vehicle body 5 is ACC on or IG on, for example.

  In step 102, the tire ID temporary registration unit 22 sets the operation mode of the TPMS receiver 12 to the temporary registration mode, and executes the tire ID temporary registration operation for a certain period of time. In the temporary registration mode, only the ID registration operation is performed without executing the low pressure threshold determination of the tire pressure.

  In step 103, the tire ID temporary registration unit 22 determines whether or not the vehicle 1 has started traveling, that is, traveling accompanied by generation of vehicle speed, based on the detection result of the vehicle traveling start detection unit 19. At this time, if the vehicle 1 has not started running, the process waits in step 102, and if the vehicle 1 has started running, the process proceeds to step 104.

  In step 104, the tire ID temporary registration unit 22 determines whether or not the TPMS receiver 12 has received the tire pressure signal Stp. At this time, if the TPMS receiver 12 has not received the tire pressure signal Stp, the process returns to step 103, and if the TPMS receiver 12 has received the tire pressure signal Stp, the process proceeds to step 105.

In step 105, the received signal strength measuring unit 21 measures the received signal strength of the tire pressure signal Stp received at this time.
In step 106, the tire ID temporary registration unit 22 determines whether the tire 2 has started rotating, that is, whether the tire 2 is in a rotating state, based on the detection result of the tire rotation start detecting unit 20. That is, when the TPMS receiver 12 receives the tire pressure signal Stp from the tire communication device 4, the tire rotation start information Drt in the tire pressure signal Stp is checked to determine whether the tire 2 is in the rotation start state. Determined. At this time, if the tire 2 has not started rotating, the process returns to step 103, and if the tire 2 has started rotating, the process proceeds to step 107.

  In step 107, the tire ID temporary registration unit 22 recognizes both that the tire 2 has started to rotate and that the vehicle 1 has started to travel, and therefore determines that the tire ID can be temporarily registered. The tire ID temporary registration unit 22 temporarily registers the tire ID received at this time in the memory 14 including the received signal strength. That is, the tire ID temporary registration unit 22 temporarily registers the tire ID and the received signal strength in association with each other in the memory 14.

  In step 108, the tire ID temporary registration unit 22 determines whether or not the temporary registration mode has ended. That is, the tire ID temporary registration unit 22 determines whether or not a predetermined time has elapsed since the temporary registration mode was started. If the predetermined time has not elapsed, the process returns to step 103 and continues the temporary registration mode. Temporary registration of other tire IDs is executed. On the other hand, if the predetermined time has elapsed, the temporary registration mode is terminated and the routine proceeds to step 109.

  In step 109, the tire ID main registration unit 23 performs main registration of four tire IDs having high received signal strengths among the temporarily registered tire IDs in the memory 14 as tire IDs of the host vehicle 1a.

  By the way, as shown in FIG. 3, the TPMS receiver 12 of the own vehicle 1a has a short distance from the tire communication device 4 of the own vehicle 1a, whereas the tire communication device 4 of the other vehicle 1b traveling around the The distance is longer than that. Therefore, when the TPMS receiver 12 of the host vehicle 1a receives the tire pressure signal Stp from both the host vehicle 1a and the other vehicle 1b, the tire pressure signal Stp received from the tire communication device 4 of the host vehicle 1a has a received signal strength. On the other hand, the tire pressure signal Stp received from the tire communication device 4 of the other vehicle 1b should be low in received signal strength.

  Therefore, a plurality of tire IDs temporarily registered in the TPMS receiver 12 are highly likely to be tire IDs transmitted from the tire communication device 4 of the own vehicle 1a that have a high received signal strength. Therefore, the tire ID main registration unit 23 performs main registration in the memory 14 as four tire IDs of the own vehicle 1a among the temporarily registered tire IDs.

  In step 110, the erroneous registration determination unit 24 determines erroneous registration of the registered tire ID. At this time, the misregistration determination unit 24 determines that the tire ID is valid if the registered tire ID can be received by the TPMS receiver 12 during a certain period after the main registration. On the other hand, if the registered tire ID cannot be received for a certain period after the main registration, the tire ID is processed as an erroneous registration ID, and the temporarily registered tire ID that was not selected during the main registration is displayed. Among them, the tire ID having the highest received signal strength is advanced and registered as the tire ID of the host vehicle 1a.

  As described above, in this example, when the TPMS receiver 12 enters the temporary registration mode, if the vehicle 1 is in the running state, the tire ID received by the TPMS receiver 12 is temporarily registered. Of the temporarily registered tire IDs, four with high received signal strength are registered in the TPMS receiver 12 as tire IDs of the host vehicle 1a. Therefore, since the tire ID can be registered in the TPMS receiver 12 without using other components (for example, an initiator or the like), the structure of the tire ID automatic registration system 17 can be simplified.

  In addition, after the tire ID is fully registered, whether or not the registered tire ID is received is monitored over a certain period, and whether or not the registered tire ID can be received is determined, thereby validating the registered tire ID. Determine sex. And when this registration tire ID cannot be received in a fixed period, it processes that the tire ID was misregistered, erases the ID, and rewrites it with another ID. Therefore, even if the tire ID is erroneously registered, the tire ID can be changed to the correct tire ID, so that the registration accuracy of the tire ID can be ensured.

According to the configuration of the present embodiment, the following effects can be obtained.
(1) In the temporary registration mode, when the TPMS receiver 12 receives the tire ID from the tire communication device 4, if the vehicle 1 is running, the tire ID is temporarily registered, and the tire ID is received every time the tire ID is received. Will be provisionally registered. When the tire ID is temporarily registered, the received signal strength when the tire ID is received is also temporarily registered. Then, at the end of the provisional registration mode, four tire IDs having high received signal strengths among the provisionally registered tire IDs are registered in the TPMS receiver 12 as tire IDs of the own vehicle. Therefore, for example, the tire ID can be automatically registered in the TPMS receiver 12 without using other components such as an initiator, so that the tire ID automatic registration system 17 can have a simple structure. In addition, since the tire ID is registered in the TPMS receiver 12 through temporary registration and temporary registration, the tire ID registration accuracy can be ensured.

  (2) After the main registration of the tire ID, the reception status of the tire ID is monitored to determine whether there is an erroneous registration of the tire ID. Therefore, even if the tire ID is misregistered, this misregistration can be detected and the tire ID can be rewritten to another regular tire ID. Therefore, the effect of securing the registration accuracy of the tire ID is enhanced.

  (3) Of the temporarily registered tire IDs, the one having a high received signal strength is fully registered as the tire ID of the host vehicle 1a. Therefore, since the tire ID to be permanently registered is identified by a highly accurate method of confirming with the received signal strength, the effect of ensuring the registration accuracy of the tire ID is enhanced.

  (4) Since it is determined that the vehicle 1 is traveling when the vehicle traveling can be detected by both the vehicle speed and the tire rotation, it is more accurately determined whether or not the vehicle 1 is traveling. Can do. Therefore, the effect of securing the accuracy of temporary registration of the tire ID is enhanced.

  (5) When the tire 2 rotates, the tire communication device 4 simply takes the operation of transmitting the tire air pressure signal Stp (including the tire rotation start information Drt) regardless of the normal operation and the tire ID registration operation. Therefore, it is possible to cause the tire communication device 4 to execute the normal operation and the ID registration operation without being aware of the operation content, so that the processing imposed on the tire communication device 4 can be simplified.

Note that the embodiment is not limited to the configuration described so far, and may be modified as follows.
The rotation information is not limited to the tire rotation start information Drt, but may be data that notifies the TPMS receiver 12 of the rotation number (rotation speed) of the tire 2, for example.

  The ID registration operation is not limited to being performed every time the ignition switch is turned on, and may be performed at a certain time interval, for example. For example, the process may be started when the TPMS receiver 12 receives an ID different from the tire ID registered in the TPMS receiver 12.

The main registration is not limited to four tire IDs having a high reception signal strength among the temporarily registered tire IDs, and may be, for example, a large number of receptions within a predetermined time.
In the ID registration mode, the radio wave for ID notification transmitted from the tire communication device 4 is not limited to the tire pressure signal Stp. For example, in the ID registration mode, a radio wave dedicated to ID registration may be transmitted from the tire communication device 4, and temporary registration → main registration may be performed using this radio wave.

  The tire pressure monitoring system 3 may employ either a constant transmission type or an initiator type. In the initiator type, the tire communication device 4 is selectively transmitted by radio waves with an initiator provided in the vehicle body 5.

The frequency of radio waves used in the tire pressure monitoring system 3 can be changed as appropriate. Moreover, it is not limited to a frequency differing in the outward path | route of an electromagnetic wave, and a return path | route, It is good also as the same.
A spare tire may be included in the monitoring tire of the tire pressure monitoring system 3.

The data (information) included in the tire pressure signal Stp can be changed as appropriate.
-Vehicle running detection is not limited to confirming both vehicle speed and tire rotation, and only one of them may be detected.

-When changing to other tire ID at the time of erroneous registration detection, you may replace with tire ID which received most among tire ID which was not employ | adopted.
The erroneous registration determination of the main registration tire ID is not limited to a method of confirming whether or not the main registration tire ID can be simply received during normal operation. For example, a method of determining whether or not a predetermined number of receptions can be performed at a certain reception intensity for a predetermined time may be employed.

  The travel detection means is not limited to the vehicle travel start detection unit 19 and the tire rotation start detection unit 20. For example, the presence or absence of depression of the accelerator pedal of the vehicle 1 may be detected, and when the depression operation of the accelerator pedal is detected, it may be detected that the vehicle is traveling.
