Description

Technical Field

[0001] The present disclosure relates to the field of intelligent vehicle technology, and in particular to a door control sensor, system, and vehicle. Background Art

[0002] With the application of intelligent automotive technology and the development of intelligent industry, cars are becoming increasingly intelligent, comfortable, and convenient. Among them, the tailgate kick sensor allows users to open the trunk hands-free. It is a smart tailgate and trunk sensor switch product that uses a variety of sensing methods, including ultrasonic, infrared, capacitive, and lidar sensors. Capacitive sensors have low power consumption and are always powered when installed and in use. Even after the vehicle is locked, the tailgate kick sensor remains active. When a kick signal is detected, it notifies the door controller to open the tailgate. However, because the tailgate kick sensor lacks a target indicator, users cannot determine the kick location, resulting in low usage.

[0003] In the current related technology, a projection device is added to the car tailgate kick sensor to project a light spot on the ground as an indicator to prompt the user where to kick or step, thereby enhancing the user experience.

[0004] However, after-installed tailgate kick sensors usually cannot communicate with the entire vehicle, and there is a problem of needing to disassemble the sensor wiring harness and related structural parts, making it difficult to upgrade the sensor firmware. Utility Model Content

[0049] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0050] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0051] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0052] Figure 1 The structure of a vehicle door control sensor provided by an exemplary embodiment of the present invention is disclosed. The vehicle door control sensor can be applied to a vehicle to control the opening and closing of the vehicle door. Figure 1 As shown, the door control sensor includes a main control module 1, a first Bluetooth module 2, and a sensor module 3. The main control module 1 includes a storage unit 11.

[0053] The sensor module 3 is connected to the main control module 1 and is used to collect sensor data. The sensor data is collected by the sensor module 3 in the corresponding area of the above-mentioned light spot and is used to identify the door control action. Optionally, the sensor module 3 can adopt an ultrasonic sensor module, an infrared sensor module, a capacitive sensor module, a millimeter-wave radar sensor module, a lidar sensor module, etc. Schematically, the sensor module 3 adopts a laser time-of-flight (TOF) sensor module, which emits a laser toward the ground at a certain frequency, and determines the distance value between the sensor and the ground object based on the time from the laser emission to the reflection. Its sensor data includes the distance value.

[0054] The first Bluetooth module 2 is connected to the main control module 1 and is configured to establish a Bluetooth connection with the second Bluetooth module 6 in the paired mobile device, receive data packets containing upgrade files sent by the second Bluetooth module 6 in the mobile device, and forward the received data packets containing the upgrade files to the main control module 1. Illustratively, the upgrade files include files for upgrading the firmware of the door control sensor.

[0055] The main control module 1 is respectively connected to the sensor module 3, the first Bluetooth module 2 and the door controller 5 on the vehicle, and is used to send a door control signal to the door controller 5 when a door control action is recognized based on the sensor data, so that the door controller controls the opening or closing of the vehicle door; and write the data packet of the upgrade file sent by the first Bluetooth module 2 into the storage unit 11 to upgrade the firmware of the door control sensor.

[0056] The main control module may include, but is not limited to, an intelligent sensor processing unit (ISPU), a central processing unit (CPU), or other processing units with data processing and / or instruction execution capabilities to control the sensor module 3, the first Bluetooth module 2, and the vehicle door controller 5. The door controller may be a controller that independently controls the vehicle door, such as a tailgate controller when the door to be controlled is the tailgate; alternatively, the door controller may be a vehicle controller, a body controller, a Passive Entry Passive Start (PEPS) controller, etc.

[0057] Illustratively, the main control module 1 inputs sensor data into a neural network model for action recognition to obtain a recognition result. Alternatively, the main control module 1 determines whether the sensor data meets a threshold standard in a preset condition to obtain a recognition result. In response to the recognition result indicating the presence of a door control action (e.g., a foot stepping into the light spot area), if the door is currently closed, the main control module 1 sends a door opening signal to the door controller 5; if the door is currently open, the main control module 1 sends a door closing signal to the door controller 5.

[0058] Optionally, a boot loader is provided in the main control module 1. After the main control module 1 receives the data packet of the upgrade file, it writes it into the storage unit 11 through the boot loader, replaces the data packet of the historical upgrade file in the storage unit 11, and restarts the sensor, thereby completing the firmware upgrade.

[0059] In one possible application scenario, a user can first receive a data packet of an upgrade file sent by a server through a mobile terminal. When the user brings the mobile terminal close to the vehicle, the second Bluetooth module 6 of the mobile terminal establishes a Bluetooth connection with the first Bluetooth module 2 in the sensor. The mobile terminal can then display a prompt message prompting the user to upgrade the sensor. Upon receiving the upgrade confirmation operation, the mobile terminal sends the data packet of the upgrade file to the first Bluetooth module 2 via the second Bluetooth module 6. The second Bluetooth module 2 then transmits the data packet of the upgrade file to the main control module 1. When the main control module 1 confirms that the application has been successfully upgraded, it generates an upgrade success signal and sends it to the mobile terminal via the first Bluetooth module 2 to confirm that the upgrade package has been successfully installed and run. Correspondingly, if the upgrade package fails to run after installation, the main control module 1 sends an upgrade failure signal to the mobile terminal via the first Bluetooth module 2.

[0060] Based on the embodiment of the present disclosure, a first Bluetooth module is provided in the door control sensor. After the first Bluetooth module establishes a Bluetooth connection with the second Bluetooth module in the paired mobile device, it can receive a data packet of an upgrade file sent by the mobile device, and forward the received data packet of the upgrade file to the main control module in the sensor. After the main control module receives the data packet of the upgrade file sent by the first Bluetooth module, it writes the data packet of the upgrade file into the storage unit of the main control module, thereby upgrading the firmware of the sensor. Even if the sensor cannot communicate with the entire vehicle, the firmware of the door control sensor can be upgraded without disassembling the sensor wiring harness and related structural parts. The upgrade cost is low and the sensor upgrade efficiency is improved.

[0061] In one possible implementation, Figure 2As shown, the first Bluetooth module 2 includes a first communication interface 21, the main control module 1 includes an upgrade unit 12 and a second communication interface 13, the first communication interface 21 is connected to the second communication interface 13, and the upgrade unit 12 is connected to the second communication interface 13 and the storage unit 11 respectively.

[0062] The first communication interface 21 is used to send data packets of upgrade files to the second communication interface 13 .

[0063] The upgrading unit 12 is configured to receive a data packet of an upgrading file through the second communication interface 13 and write the data packet into the storage unit 11 .

[0064] The first communication interface 21 and the second communication interface 13 may be communication interfaces such as a serial peripheral interface (SPI), an RS-232 interface, or a universal asynchronous receiver / transmitter (UART).

[0065] Optionally, since the upgrade file's data packet typically has a large data volume, the second Bluetooth module 6 of the mobile terminal can split the data packet into at least two data blocks before transmitting it to the first Bluetooth module 2, and then send the data blocks to the first Bluetooth module 2 in batches. After each data block is received by the main control module 1 through the first Bluetooth module 2, the first Bluetooth module 2 sends back a signal to the second Bluetooth module 6 indicating successful receipt of the current data block, causing the second Bluetooth module 6 to send the next data block. After receiving all data blocks, the main control module 1 can perform a data integrity check to determine whether all data blocks of the upgrade file's data packet have been successfully received. If the upgrade file's data packet is complete, the data packet is written to the storage unit 11. In an illustrative example, the second Bluetooth module 6 can add sequence numbers to each data block in the order in which the data blocks are divided, for example, adding sequence number 001 to the first data block, sequence number 002 to the second data block, and so on until the last data block. An end marker is then added to the last data block, and the main control module 1 can continue to check the sequence numbers in each data block to see if any data blocks are missing. The present embodiment does not limit the data block segmentation method or integrity check method.

[0066] The above embodiment demonstrates that the sensor can be remotely upgraded by providing the first Bluetooth module 2. During the sensor upgrade and development process, technicians need to refer to sensor data from abnormal scenarios, such as scenarios where a user's door control action is not recognized or an invalid action is mistakenly identified as a door control action. This data is then analyzed to improve sensor performance. However, when the door control sensor cannot communicate with the vehicle, data recovery is impossible. Certain abnormal scenarios are difficult or costly to reproduce remotely, hindering product upgrades.

[0067] In one possible implementation, Figure 2 As shown, the sensor further includes a storage module 8. The storage module 8 is connected to the main control module 1 and the sensor module 3 respectively, and is used to store the sensor data collected by the sensor module 3.

[0068] The main control module 1 is configured to read the sensing data from the storage module 8 and transmit the sensing data to the second Bluetooth module 6 via the first Bluetooth module 2 after receiving the data request via the first Bluetooth module 2 .

[0069] Among them, the storage module 8 may include volatile memory and / or non-volatile memory. The volatile memory may include, for example, random access memory (RAM) and / or cache memory, and the non-volatile memory may include, for example, read-only memory (ROM), flash memory, etc.

[0070] Optionally, the storage module 8 is configured to roll over and save sensor data collected within a preset time period, and to remove sensor data collected more than the preset time period from the current moment. For example, the sensor data collected within the last five minutes may be rolled over and saved, and at 09:06, sensor data collected before 09:01 may be deleted, leaving only the sensor data collected between 09:01 and 09:06. Since users typically report data when door control anomalies occur, sensor data collected earlier does not constitute data from abnormal scenarios. Rolling over and saving can reduce the amount of data stored by the sensor and avoid wasting memory resources.

[0071] The above-mentioned data request is generated by the second Bluetooth module 6 of the mobile terminal and sent to the first Bluetooth module 2. Illustratively, the mobile terminal is provided with an application module 9. When a user discovers an abnormality in the door control, they can perform a data acquisition operation through the mobile terminal. In response to the data acquisition operation, the application module 9 generates a data request through the second Bluetooth module 6 when a Bluetooth connection is established between the first Bluetooth module 2 and the second Bluetooth module 6. Illustratively, the application module 9 may include, but is not limited to, applications, mini-programs, platform official accounts, etc. corresponding to the door control sensor. The application module 9 can communicate with the corresponding server via the network.

[0072] In one possible embodiment, after receiving the data request, the main control module 1 can first extract the file list from the storage module 8 and transmit the file list to the second Bluetooth module 6 through the first Bluetooth module 2. The file list includes the data collection time and data file identifier corresponding to each sensor data. The user can manually select the target file identifier containing the sensor data in the abnormal scenario through the data acquisition operation according to the time of the door control abnormality and the data collection time corresponding to each file identifier in the file list. The second Bluetooth module 6 sends the target file identifier to the first Bluetooth module 2 based on the data acquisition operation. After the main control module 1 receives the target file identifier through the first Bluetooth module 2, it extracts the target sensor data corresponding to the target file identifier from the storage module 8, and transmits the target sensor data to the second Bluetooth module 6 through the first Bluetooth module 2. After the mobile terminal receives the target sensor data through the second Bluetooth module 6, it reports to the server 7 through the application module 9 so that the technicians can recover and analyze the abnormal data. The user can filter out the target file identifier of the target sensor data in the door control abnormal scenario based on the data collection time corresponding to each data in the list, so that the mobile terminal sends a data acquisition request containing the target file identifier. On the one hand, it can accurately obtain the sensor data of the door control abnormal scenario and reduce the interference of normal sensor data. On the other hand, it can reduce the amount of data transmitted between the first Bluetooth module and the second Bluetooth module, and improve the efficiency of reporting abnormal data.

[0073] Optionally, the storage module 8 can store the sensor data in segments. For example, the sensor data can be divided into time units with a preset duration (e.g., 30 seconds), and each segment of sensor data corresponds to a unique file identifier and a corresponding data collection period, so as to avoid displaying too many data items in the file list, which would make the user's data acquisition operation more cumbersome. Alternatively, the sensor data can be divided into data units with preset data items (e.g., 100 items). The embodiment of the present application does not limit the storage method of the sensor data.

[0074] Optionally, when the amount of sensor data to be transmitted is large, the first Bluetooth module 2 may divide the sensor data into multiple data blocks and transmit the data to the second Bluetooth module 6 in batches.

[0075] In the disclosed embodiment, a first Bluetooth module is provided in the door control sensor, and the first Bluetooth module is connected to the main control module in the door control sensor. When the first Bluetooth module detects a data request sent by the paired mobile terminal through the second Bluetooth module, the first Bluetooth module obtains sensor data through the main control module, and uses a Bluetooth signal to send the sensor data to the mobile terminal, so that the mobile terminal uploads the sensor data to the server through the network. The user can report relevant sensor data to the background server when the door control action is not recognized or the sensor mistakenly recognizes an invalid action as a door control action, thereby realizing remote recovery of sensor data in sensor failure scenarios, which helps technicians to upgrade and develop sensors based on recovered data, thereby improving the accuracy of automatic door control.

[0076] In one possible implementation, Figure 2 As shown, the door control sensor may further include a projection module 4 , and the main control module 1 may further include a micro control unit 14 and a projection drive interface 15 .

[0077] The microcontroller unit 14 is connected to the sensor module 1 and the door controller 5, and is used to control the operating mode of the sensor module and send door control signals to the door controller 5. The microcontroller unit 14 may integrate a processing unit, memory, and various interfaces. For example, it may communicate with the sensor module 1 and the door controller 5 via an SPI interface, and perform data processing and related instruction execution via the CPU.

[0078] The projection drive interface 15 is connected to the projection module 4 and is used to send a drive signal generated by the micro control unit 14 to the projection module 4 to drive the projection module 4 to project an indication light spot.

[0079] Illustratively, projection module 4 projects an indicator light spot on the ground, which indicates to the user the location at which the door should be opened or closed. Optionally, the preset door opening actions may include kicking, stepping, waving, etc., and the indicator light spot may indicate the user performing the preset action at the light spot location. Optionally, projection module 1 includes a light emitting diode (LED) as a light source for projecting light onto the ground.

[0080] Schematically, the projection module 4 may include a projection drive unit, a projection lamp and a projection lens. The projection drive unit is connected to the projection drive interface 15 of the main control module 1. The microcontroller unit 14 of the main control module 1 is used to send a drive signal, such as a pulse width modulation (PWM) signal, to the projection drive unit through the projection drive interface 15 in a working state. After receiving the drive signal, the projection drive unit drives the projection lamp and the projection lens to enter the working state to project an indication light spot.

[0081] The disclosed embodiments further provide a vehicle door control sensor system, comprising a mobile terminal and the vehicle door control sensors described in the aforementioned embodiments. After a first Bluetooth module 2 in the vehicle door control sensor and a second Bluetooth module 6 in the mobile terminal complete Bluetooth pairing and establish a Bluetooth connection, the second Bluetooth module 6 transmits a data packet containing an upgrade file to the first Bluetooth module 2. The main control module 1 in the vehicle door control sensor then uses the received upgrade file from the first Bluetooth module 2 to perform a firmware upgrade.

[0082] In one possible application scenario, a user can first receive a data packet of an upgrade file sent by a server through a mobile terminal. When the user brings the mobile terminal close to the vehicle, the second Bluetooth module 6 of the mobile terminal establishes a Bluetooth connection with the first Bluetooth module 2 in the sensor. The mobile terminal can then display a prompt message prompting the user to upgrade the sensor. Upon receiving the upgrade confirmation operation, the mobile terminal sends the data packet of the upgrade file to the first Bluetooth module 2 via the second Bluetooth module 6, and the second Bluetooth module 2 then transmits the data packet of the upgrade file to the main control module 1. When the main control module 1 confirms that the application has been successfully upgraded, it generates an upgrade success signal and sends it to the mobile terminal via the first Bluetooth module 2 to confirm that the upgrade package has been successfully installed and run. Correspondingly, if the upgrade package fails to run after installation, the main control module 1 sends an upgrade failure signal to the mobile terminal via the first Bluetooth module 2, and the mobile terminal is used to display the sensor upgrade results.

[0083] Optionally, since the data packet of the upgrade file is usually large in size, the second Bluetooth module 6 of the mobile terminal can split the data packet into at least two data blocks before transmitting the data packet to the first Bluetooth module 2, and send the data blocks to the first Bluetooth module 2 in batches. After the main control module 1 receives a data block through the first Bluetooth module 2, it feeds back a signal indicating the successful reception of the current data block to the second Bluetooth module 6 through the first Bluetooth module 2, so that the second Bluetooth module 6 sends the next data block. After receiving all the data blocks, the main control module 1 can perform a data integrity check to determine whether all the data blocks of the upgrade file data packet have been successfully received. If the upgrade file data packet is confirmed to be complete, the data packet will be written into the storage unit 11. Accordingly, the mobile terminal 2 can display a transmission progress bar of the upgrade file data packet on the screen.

[0084] The second Bluetooth module 6 and the first Bluetooth module 2 have completed Bluetooth pairing. The user can pre-pair the second Bluetooth module 6 with the door control sensor using a mobile terminal to successfully pair the two. After successful pairing, when the user brings the mobile terminal close to the sensor, the first Bluetooth module 2 automatically establishes a Bluetooth connection with the second Bluetooth module 6. Alternatively, the mobile terminal can be a mobile phone, tablet, smart key, portable computer, or other terminal.

[0085] Based on the embodiment of the present disclosure, a second Bluetooth module is provided in the mobile terminal. After the second Bluetooth module establishes a Bluetooth connection with the first Bluetooth module in the paired sensor, it can send a data packet of the upgrade file to the sensor. The first Bluetooth module in the sensor forwards the received data packet of the upgrade file to the main control module. After the main control module receives the data packet of the upgrade file sent by the first Bluetooth module, the data packet of the upgrade file is written into the storage unit of the main control module, thereby upgrading the firmware of the sensor. Even if the sensor cannot communicate with the entire vehicle, the firmware of the door control sensor can also be upgraded without disassembling the sensor wiring harness and related structural parts. The upgrade cost is low and the sensor upgrade efficiency is improved.

[0086] In one possible implementation, Figure 2 As shown, the mobile terminal further includes a camera 10 and an application module 9 that are communicatively connected, and the application module 9 is further communicatively connected to the second Bluetooth module 6 .

[0087] The camera 10 is used to capture scene images (or scene videos). In response to the user's image capture operation, the camera 10 performs image capture.

[0088] The application module 9 is configured to instruct the second Bluetooth module 6 to send a data request to the first Bluetooth module 2, receive the sensor data forwarded by the second Bluetooth module 6, and upload the sensor data and scene image to the corresponding server 7. The application module 9 may include, but is not limited to, applications, mini-programs, and platform public accounts corresponding to the door control sensors. The application module 9 can communicate with the corresponding server via a network.

[0089] Optionally, after receiving the data request, the main control module 1 can first extract a file list from the storage module 8 and transmit the file list to the second Bluetooth module 6 through the first Bluetooth module 2. The file list includes the data collection time and data file identifier corresponding to each sensor data. The mobile terminal displays the file list, allowing the user to manually select the target file identifier containing the sensor data in the abnormal scenario through the data acquisition operation based on the time of the door control abnormality and the data collection time corresponding to each file identifier in the file list. The second Bluetooth module 6 sends the target file identifier to the first Bluetooth module 2 based on the data acquisition operation. After the main control module 1 receives the target file identifier through the first Bluetooth module 2, it extracts the target sensor data corresponding to the target file identifier from the storage module 8 and transmits the target sensor data to the second Bluetooth module 6 through the first Bluetooth module 2. After the mobile terminal receives the target sensor data through the second Bluetooth module 6, it reports to the server 7 through the application module 9 so that technical personnel can recover and analyze the abnormal data. The user can filter out the target file identifier of the target sensor data in the door control abnormal scenario based on the data collection time corresponding to each data in the list, so that the mobile terminal sends a data acquisition request containing the target file identifier. On the one hand, it can accurately obtain the sensor data of the door control abnormal scenario and reduce the interference of normal sensor data. On the other hand, it can reduce the amount of data transmitted between the first Bluetooth module and the second Bluetooth module, and improve the efficiency of reporting abnormal data.

[0090] When a door control anomaly occurs, the user can use the mobile terminal to obtain sensor data from the sensor and also use the mobile terminal to capture scene images (for example, by photographing the scene near the tailgate, or reproducing the door control action during the anomaly and capturing a video). The application module 9 uploads the sensor data and scene images to the corresponding server, allowing technicians to analyze the cause of the sensor anomaly based on the scene images and sensor data.

[0091] The door control sensor provided by the embodiment of the present disclosure is used for a vehicle. Figure 3 , which shows a structural block diagram of a vehicle provided by an exemplary embodiment of the present disclosure.
