Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein.
The embodiment of the invention is mainly applied to a scene that a tire pressure monitoring system of a vehicle performs matching learning on a tire pressure sensor arranged in a wheel. Fig. 1 shows a schematic diagram of device connection in a tire pressure sensor matching learning scenario according to an embodiment of the present invention. As shown in fig. 1, the tire pressure sensor matching system includes a tire pressure device and an auxiliary sensor; a tire pressure monitoring system of a vehicle includes an Electronic Control Unit (ECU) and a tire pressure sensor mounted to a wheel. Generally, a tire pressure sensor (for example, the tire pressure sensors 1 to 4 in fig. 1) is installed in each of tires of four wheels of a vehicle, and a tire pressure sensor is also installed in a spare tire of some vehicle types. The tire pressure device may be used to communicate with a tire pressure monitoring system. The tire pressure equipment can be connected and communicated with the tire pressure sensor in a wireless mode, such as low-frequency signals, high-frequency signals, Bluetooth and the like; and the ECU is connected and communicated with the ECU in a wired mode or a wireless mode, wherein the wired mode is connected with an OBD (On-Board Diagnostics) interface, and the wireless mode is high-frequency signals, Bluetooth or Wi-Fi and the like. Preferably, the tire pressure equipment is dedicated matching tool equipment, and may be a PC, a mobile phone, a tablet computer, or the like that has at least one of the above communication modes and can communicate with each equipment in a connected manner. For a dedicated tire pressure device, in order to control the device cost, generally, the tire pressure device has only low frequency signal transmission and high frequency signal reception functions. The auxiliary sensor can be connected and communicated with the tire pressure equipment or the tire pressure sensor in a wireless mode, such as low-frequency signals, high-frequency signals, Bluetooth and the like. The auxiliary sensor can be in wireless connection communication with the ECU, such as high-frequency signals, Bluetooth or Wi-Fi. Preferably, the low frequency signal includes a radio frequency signal of 60-200KHz, and the high frequency signal includes a radio frequency signal of 300-900 MHz.
Fig. 2 is a flowchart illustrating a tire pressure sensor matching method according to an embodiment of the present invention. The method is applied to the tire pressure sensor matching system. As shown in fig. 2, the method comprises the steps of:
step 210: the auxiliary sensor acquires and stores learning data of the tire pressure sensor; wherein the learning data includes identification data of the tire pressure sensor.
The learning data may include tire data such as tire pressure and temperature in addition to an Identification (ID) of the tire pressure sensor. The tire pressure sensor identifier is used for uniquely marking one tire pressure sensor.
Preferably, according to different learning data obtaining manners, the step 210 may specifically include:
the first mode is to directly obtain the tire pressure sensor of the wheel.
Step 211: the auxiliary sensor sends an activation signal to the tire pressure sensor;
in particular, the auxiliary sensor may send a low frequency or bluetooth activation signal near the wheel to the tire pressure sensor to be matched.
Step 212: the auxiliary sensor receives and stores the learning data sent by the tire pressure sensor.
Specifically, after receiving the low frequency or bluetooth activation signal, the tire pressure sensor to be matched sends a high frequency signal to the auxiliary sensor, where the high frequency signal includes the ID of the tire pressure sensor, and may further include the tire pressure and temperature data of the tire. The auxiliary sensor receives and stores the learning data of the tire pressure sensor.
And secondly, obtaining from the tire pressure equipment.
Step 213: the auxiliary sensor sends a data acquisition request to the tire pressure equipment;
specifically, the auxiliary sensor sends a data acquisition request to the tire pressure device via a low frequency or bluetooth signal. Alternatively, the tire pressure device may also actively transmit the above-described learning data of the tire pressure sensor to the auxiliary sensor, and in this case, step 213 may be omitted.
Step 214: the learning data of the tire pressure sensor is received and stored from the tire pressure device.
Specifically, the tire pressure device may transmit the ID of the tire pressure sensor to the auxiliary sensor in a wired manner or a wireless manner (low frequency signal or bluetooth), and further may include tire pressure and temperature data of the tire. The auxiliary sensor receives and stores the learning data of the tire pressure sensor.
Optionally, before step 214, the method includes:
step 215: the tire pressure equipment sends an activation signal to a tire pressure sensor;
in particular, the tire pressure device may transmit a low frequency or bluetooth activation signal to the tire pressure sensor to be matched in the vicinity of the wheel.
Step 216: the tire pressure device receives and stores the learning data transmitted by the tire pressure sensor.
Specifically, after receiving the low frequency or bluetooth activation signal, the tire pressure sensor to be matched sends a high frequency signal to the tire pressure device, where the high frequency signal includes the ID of the tire pressure sensor, and may further include the tire pressure and temperature data of the tire. The tire pressure device receives and stores the learning data of the tire pressure sensor.
Optionally, before step 214, the method includes:
step 217: the tire pressure equipment acquires the ID of the tire pressure sensor in a manual input mode and stores the ID.
Specifically, the manual input method includes: keyboard input, touch screen input, voice input, or swipe code input, etc. After the user manually inputs the ID of the tire pressure device to be matched, the tire pressure device saves it.
Obviously, compared with the second acquisition mode, the first acquisition mode reduces the step of transferring the learning data from the tire pressure equipment, so that the process is simpler, and the learning data acquisition is more direct and efficient.
It should be noted that, in the above steps, the auxiliary sensor may acquire the learning data of a plurality of tire pressure sensors, for example, the auxiliary sensor may acquire and store the learning data of different tire pressure sensors to be matched respectively, or may acquire and store the learning data of the tire pressure sensors to be matched from the tire pressure device at one time. Therefore, the matching operation of the tire pressure sensor can be further simplified, and the matching efficiency is improved.
Step 220: the auxiliary sensor judges whether the electronic control unit starts a high-frequency learning mode.
Preferably, step 220 may be preceded by:
step 221: starting a high-frequency learning mode of a vehicle tire pressure monitoring system;
specifically, the tire pressure device may be connected to the ECU of the tire pressure monitoring system in a wired manner (e.g., connected to an OBD interface of the vehicle) to initiate a learning mode of the tire pressure monitoring system; the tire pressure monitoring system can also be connected with the ECU in a wireless mode (such as high-frequency signals or Bluetooth) to initiate a learning mode of the tire pressure monitoring system; the tire pressure monitoring system of the vehicle may also be manually operated to initiate a learning mode.
Step 222: when the tire pressure monitoring system starts a high-frequency learning mode, the tire pressure equipment sends a trigger signal to the auxiliary sensor.
Tire pressure equipment accessible wired mode or wireless mode learn that tire pressure monitoring system's ECU has opened the study mode, and at this moment, tire pressure equipment can send low frequency or bluetooth trigger signal to auxiliary sensor, also can send trigger signal to auxiliary sensor through wired mode. The trigger signal is a high frequency learning mode start signal.
Specifically, step 220 may include:
step 223: the auxiliary sensor receives a trigger signal sent by the tire pressure equipment;
step 224: judging whether the trigger signal is a high-frequency learning mode starting signal or not; and if so, determining that the electronic control unit starts a high-frequency learning mode.
It should be noted that step 220 may also be performed before step 210 if the auxiliary sensor is to acquire the learning data of the tire pressure sensor to be matched from the tire pressure device.
Step 230: if the judgment result is yes, the auxiliary sensor sends the learning data of the tire pressure sensor to the electronic control unit through a high-frequency wireless transmission technology, so that the electronic control unit matches the identification data of the tire pressure sensor with the corresponding wheel according to the learning data.
Preferably, step 230 may be preceded by:
step 231: the auxiliary sensor acquires communication parameters communicated with the tire pressure monitoring system from the tire pressure equipment; the communication parameter is determined by the tire pressure equipment according to the type of the vehicle.
Specifically, the communication parameter includes a high frequency communication frequency, and further includes: baud rate, decoding mode and/or verification mode. Since parameters such as high frequency signal frequency of tire pressure monitoring systems of different vehicle types and tire pressure sensors are different, it is necessary for tire pressure equipment to determine corresponding communication parameters according to a vehicle type selected by a user. Subsequently, the tire pressure device transmits the communication parameter to the auxiliary sensor.
Accordingly, step 230 may include:
step 232: the auxiliary sensor transmits a high-frequency wireless signal containing the learning data of the tire pressure sensor to the electronic control unit with the communication parameter.
Specifically, after learning the communication parameters, the auxiliary sensor transmits a high-frequency signal including the learning data of the tire pressure sensor to the ECU of the tire pressure monitoring system at the high-frequency communication frequency.
As mentioned above, the tire pressure monitoring system generally monitors the tire pressure sensors of a plurality of wheels, and the auxiliary sensor may acquire the learning data of the plurality of tire pressure sensors before the matching learning. Specifically, the tire pressure sensor may include a first tire pressure sensor and a second tire pressure sensor, and step 230 may include:
step 233: and the auxiliary sensor sends the learning data of the first tire pressure sensor and the learning data of the second tire pressure sensor to the electronic control unit according to the wheel matching sequence of the tire pressure monitoring system.
Specifically, in step 210, the auxiliary sensor may first acquire the learning data of the first sensor or the learning data of the second sensor. For example, the auxiliary sensor may acquire the learning data of the tire pressure sensors of the four wheels of the vehicle directly or from the tire pressure device, and the order of acquiring these learning data is not limited. But must be transmitted in the order required by the tire pressure monitoring system when transmitting the learning data of each tire pressure sensor to the ECU. The auxiliary sensor may obtain a wheel matching sequence of the tire pressure monitoring system corresponding to the vehicle type from the tire pressure device. For example, the tire pressure monitoring system of this vehicle type requires that the matching sequence of the wheels is left front, right front, left rear, right rear, and spare tire, and the auxiliary sensor needs to sequentially transmit the learning data of the left front, right front, left rear, right rear wheels, and spare tire to the ECU according to the sequence. Of course, the number and sequence of the wheels matched and learned by the tire pressure monitoring system may be different according to different vehicle types, and is not limited herein.
Further, the auxiliary sensors may sequentially transmit the learning data of the tire pressure sensors of the plurality of wheels to the ECU, respectively, or may transmit the learning data of the plurality of wheels to the ECU at one time, according to the vehicle type. The auxiliary sensors can be sequentially sent according to the prompt requirement of the tire pressure monitoring system, the operation of a user or a preset sending period according to the matching sequence, the learning data of the tire pressure sensors can also be sent to the ECU at one time, and the ECU receives the learning data and sequentially analyzes the learning data packets according to the matching sequence and then respectively matches the learning data packets.
In an optional embodiment, the learning data further includes wheel information corresponding to the tire pressure sensor; step 233 includes:
step 2331: and displaying the identification data and the corresponding wheel information of the first tire pressure sensor and the identification data and the corresponding wheel information of the second tire pressure sensor.
Specifically, the auxiliary sensor may have a display function to display the stored ID of each tire pressure sensor and the corresponding wheel information to the user.
Step 2332: and when the tire pressure monitoring system prompts that the wheels corresponding to the first tire pressure sensor are matched, responding to the selection of a user, and sending the identification data of the first tire pressure sensor to the electronic control unit.
Specifically, when the system matches the wheel corresponding to the first tire pressure sensor, the user may select to send the ID of the first tire pressure sensor through the display interface of the auxiliary sensor, and then the auxiliary sensor sends the ID to the ECU.
Step 2333: and when the tire pressure monitoring system prompts that the wheels corresponding to the second tire pressure sensor are matched, responding to the selection of a user, and sending the identification data of the second tire pressure sensor to the electronic control unit.
Specifically, when the system matches the wheel corresponding to the second tire pressure sensor, the user may select to transmit the ID of the second tire pressure sensor through the display interface of the auxiliary sensor, and then the auxiliary sensor transmits the ID to the ECU.
Under the condition that a plurality of tire pressure sensors need to be matched and learned, the auxiliary sensor can learn the learning data of all the tire pressure sensors needing to be matched at one time, and when the tire pressure monitoring system starts a learning mode, the learning data of the tire pressure sensors are respectively or once sent to the ECU, so that a user can intensively complete the matching and learning of the tire pressure sensors of a plurality of wheels after the user starts the learning mode of the tire pressure monitoring system in a vehicle, the tire pressure sensors in the tires of the wheels are not required to be activated outside the vehicle for multiple times, the operation difficulty is further reduced, and the matching efficiency of the tire pressure sensors is improved.

By the method, the auxiliary sensor can store the learning data of the tire pressure sensor of the wheel to be matched in advance, when the learning mode of the tire pressure monitoring system is started, the auxiliary sensor timely sends the learning data to the electronic control unit, and an operator can complete matching of the tire pressure sensor in the tire in the vehicle, so that the operation complexity is reduced, the success rate of matching of the tire pressure sensor is greatly improved, and the matching efficiency is improved. In addition, the auxiliary sensor can be used repeatedly independently of the tire pressure equipment, particularly for the tire pressure equipment without a high-frequency transmitting function, a plurality of tire pressure equipment can share one auxiliary sensor, and the cost of the tire pressure equipment is reduced.
