[0022] Below, the exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described here.

[0023] Figure 1 1 is a flow chart of a control method of a vehicle data collection system provided by an exemplary embodiment of the present application. The control method of the vehicle data collection system is applied to a vehicle-mounted terminal in the vehicle data collection system. The vehicle data collection system includes a vehicle-mounted terminal arranged on the vehicle and a fixed terminal arranged in a specific area. When the vehicle-mounted terminal enters a preset range of the fixed terminal, the vehicle-mounted terminal and the fixed terminal establish a communication connection; Figure 1 As shown, the control method of the vehicle data acquisition system includes the following steps:

[0024] Step 110: Receive a transmission signal sent by the fixed end.

[0025] Among them, the transmission signal is a wireless signal transmitted from the fixed end to the preset range of the fixed end. When a vehicle enters a specific area, the fixed end set in the specific area will send a transmission signal to the vehicle-mounted end to inform the vehicle-mounted end that it has entered the specific area. Specifically, the fixed end may include a reader and a signal transmitter of a short-range wireless communication system (such as an RFID system), and the vehicle-mounted end may include a tag of the short-range wireless communication system (specifically including a small electronic chip and an antenna, and storing the identity information of the vehicle: a unique identification code) and a signal receiver. When the vehicle and its vehicle-mounted end enter the preset range of the fixed end, the reader of the fixed end will read the tag signal of the vehicle-mounted end, and generate a transmission signal based on the read signal. The fixed end uses a signal transmitter to send the transmission signal to the vehicle-mounted end, and the signal receiver of the vehicle-mounted end receives the transmission signal to determine that the vehicle has entered the specific area at this moment.

[0026] Preferably, in order to ensure the stability of the transmission signal, the present application can encode, modulate, filter, amplify, pre-distort and other processes on the key contents of the transmission signal when generating the transmission signal to obtain an efficient and stable transmission signal, thereby minimizing the damage and interference during the transmission process. After receiving the transmission signal sent by the fixed end, the vehicle-mounted end performs signal demodulation and decoding, analysis and conversion on the transmission signal to ensure that the transmission signal is suitable for the internal system of the vehicle. Among them, encoding is to encode the transmission signal before sending it to improve the transmission efficiency of data and provide a certain degree of error detection and correction capability for the transmission signal; modulation is to map the transmission signal to a carrier signal, by changing the amplitude, frequency or phase of the carrier, so as to facilitate the transmission of the transmission signal on radio waves or other transmission media, where the modulation can be analog (such as AM, FM) or digital (such as QAM, PSK); before the transmission signal is sent, a filter is used to limit the bandwidth of the signal and reduce possible interference to ensure the quality of the signal. The filter can weaken or remove undesirable frequency components to optimize the performance of the transmission signal; before the transmission signal is sent to the transmission medium, it is amplified to ensure that it has enough power to cover the required transmission distance; in order to offset the signal distortion during the transmission process, the transmission signal will be pre-distorted before it is sent. By pre-adjusting certain characteristics of the transmission signal, a more accurate signal can be obtained at the vehicle end. The signal received by the vehicle end is usually modulated and needs to be demodulated back to the baseband signal, and then these signals are decoded to extract the transmitted data or information, and finally the data is analyzed, interpreted and converted to make it suitable for the internal system of the vehicle.

[0027] Step 120: Obtain the working mode of the vehicle data acquisition system.

[0028] When the vehicle-mounted terminal determines that the vehicle has entered a specific area, it checks the working mode of the vehicle data collection system. The working mode of the vehicle data collection system includes data collection status (including partial data collection status and full data collection status) and data non-collected status (the vehicle is in a parked state or manually driven state). By obtaining the working mode of the vehicle data collection system, it can be determined whether information will be collected at this time.

[0029] Step 130: If the working mode is in the data collection state, some or all of the data collection devices of the vehicle data collection system are turned off.

[0030] If the working mode of the vehicle data acquisition system is the data acquisition state, that is, at this moment, at least part of the data acquisition devices of the vehicle data acquisition system are in the open or working state, in order to prevent the data acquisition devices from collecting relevant data of the specific area, the present application turns off part of the data acquisition devices or all of the data acquisition devices of the vehicle data acquisition system. Specifically, the data acquisition devices that need to be turned off are determined according to the actual situation, such as data acquisition devices that must be turned on during the automatic driving process (such as anti-collision data acquisition devices) or data acquisition devices that will not collect information in a specific area. It is not necessary to turn off. Among them, the data acquisition equipment may include laser radar, camera, GPS / IMU positioning, etc. The laser radar is used to obtain three-dimensional point cloud data of the surrounding environment, the camera is used to capture image information, and the GPS / IMU positioning data is used to obtain the position and posture information of the vehicle. It should be understood that, under the premise of ensuring safety, the vehicle should try to turn off all data acquisition devices when entering a specific area. Preferably, the present application can integrate the opening and closing functions of the data acquisition device into the electronic control unit (ECU) of the vehicle, and allow the operator or the automatic system to control the opening and closing of the data acquisition device through the software interface, that is, the opening and closing of the data acquisition device is automatically controlled by the software arranged in the electronic control unit, so as to realize the automatic closing function of the data acquisition device when entering a specific area.

[0031] A control method for a vehicle data acquisition system provided by the present application is applied to a vehicle-mounted terminal in the vehicle data acquisition system, wherein the vehicle data acquisition system includes a vehicle-mounted terminal arranged on the vehicle and a fixed terminal arranged in a specific area, wherein the vehicle-mounted terminal and the fixed terminal establish a communication connection when the vehicle-mounted terminal enters a preset range of the fixed terminal; the vehicle-mounted terminal receives a transmission signal sent by the fixed terminal, wherein the transmission signal is a wireless signal transmitted by the fixed terminal to a preset range of the fixed terminal, and obtains a working mode of the vehicle data acquisition system, and if the working mode is a data acquisition state, some or all data acquisition devices of the vehicle data acquisition system are turned off; that is, by setting a fixed terminal in a specific area, when a vehicle enters, transmission information is sent to the vehicle-mounted terminal, and after receiving the transmission signal, the vehicle-mounted terminal checks the working mode of the vehicle data acquisition system, and if the data acquisition device is in a data acquisition state at this time, some or all data acquisition devices are turned off to stop acquisition, thereby effectively preventing information leakage in a specific area.

[0032] In one embodiment, the specific implementation of the above step 120 may be: obtaining the switch state of the data acquisition device; if the switch state of the data acquisition device is the on state, determining that the working mode is the data acquisition state.

[0033] When it is determined that the vehicle has entered a specific area, the present application first obtains the switch state of the data acquisition device to determine whether the data acquisition device is turned on. If the data acquisition device is turned on (partially turned on or fully turned on), it can be determined that the working mode of the vehicle data acquisition system is the data acquisition state, and there is a risk of collecting information at this time. It should be understood that under normal circumstances, the driving state of the vehicle (specifically including the automatic driving state, the assisted driving state and the manual driving state) and the working mode of the vehicle data acquisition system are consistent. For example, the automatic driving state or the assisted driving state requires the on-board data acquisition device to be turned on to collect data for the automatic driving system or the assisted driving system, while the manual driving state is mainly determined by the driver himself, and the data acquisition device may not be turned on to collect data (of course, the data acquisition device can also be set to be in a normally open state during the vehicle driving process). If the driving state of the vehicle is the automatic driving state or the assisted driving state, the data acquisition device is turned on at this time, that is, it is determined that the working mode of the vehicle data acquisition system is the data acquisition state, and it is necessary to turn off some or all of the data acquisition devices at this time.

[0034] In one embodiment, the control method of the vehicle data collection system may further include: if the transmission signal sent by the fixed end is not received, turning on the data collection device of the vehicle data collection system.

[0035] If the vehicle-mounted terminal does not receive the transmission signal sent by the fixed terminal, it means that the vehicle-mounted terminal and the corresponding vehicle have not entered the specific area or have left the specific area (driving out of the transmission radius of the fixed terminal). At this time, the data acquisition device of the vehicle data acquisition system can be directly turned on. That is, the present application automatically turns off part or all of the data acquisition devices when the vehicle enters a specific area, and automatically turns on the data acquisition device required for the current driving state when leaving the specific area, while ensuring the information security of the specific area without affecting the normal operation of the autonomous driving vehicle. Optionally, the present application can also first obtain the driving state of the vehicle. If the driving state of the vehicle is an autonomous driving state or an assisted driving state, it means that the vehicle needs to turn on the data acquisition device at this time to realize the autonomous driving function or the assisted driving function, then turn on the data acquisition device corresponding to the vehicle data acquisition system. If the driving state of the vehicle is a manual driving state, it means that the vehicle does not need to collect data at this time, then the data acquisition device can be temporarily not turned on.

[0036] In one embodiment, the control method of the vehicle data collection system may further include: if the working mode is in the data collection state, prompting the driver to switch to the manual driving state.

[0037] When it is determined that the vehicle-mounted terminal has entered the preset range of the fixed terminal and the working mode of the vehicle data collection system is the data collection state, that is, the data collection device is in the on state at this time, in order to prevent the data collection device from collecting information of the specific area where the fixed terminal is located and at the same time ensure the normal operation of the vehicle, this application can prompt the driver to switch to the manual driving state. That is, when the vehicle enters a specific area in the automatic driving state or the assisted driving state, the driver is prompted to drive by himself and turn off the data collection device to ensure the normal operation of the vehicle and prevent the data collection device from collecting relevant data of the specific area.

[0038] In one embodiment, after prompting the driver to switch to the manual driving state, the control method of the above-mentioned vehicle data acquisition system may also include: if the driving state of the vehicle is the assisted driving state, turning off part or all of the data acquisition devices of the vehicle data acquisition system.

[0039] After prompting the driver to switch to manual driving state, if the driver does not switch the driving state, if the driving state of the vehicle is an assisted driving state (i.e., driven by the driver and assisted by the assisted driving system, such as lane departure correction, active braking, etc.), and the assisted driving state also needs to use the data acquisition equipment to collect road condition data, in order to avoid the data acquisition equipment from collecting relevant data of a specific area, the present application can temporarily turn off the data acquisition equipment (usually the time the vehicle passes through the specific area is short), that is, temporarily turn off the assisted driving system, and the driver drives the vehicle alone. If the driving state of the vehicle is an automatic driving state, the present application can also temporarily turn off some data acquisition equipment (data acquisition equipment involving important information of a specific area), and turn on the data acquisition equipment immediately after leaving the specific area to ensure the safe operation of the vehicle. Preferably, in order to further ensure that the vehicle in the automatic driving state passes through a specific area, the present application can also use an offline map as a reference for assisted driving to improve the safety of the vehicle when passing through a specific area. Optionally, since the fixed end is set at a fixed position in a specific area, the present application can also assist the vehicle driving according to the distance between the fixed end and the vehicle-mounted end to ensure the safety of the vehicle when passing through a specific area.

[0040] In one embodiment, the specific implementation method of the above step 130 can be: if the working mode is the data acquisition state, the driving state of the vehicle is obtained; if the driving state of the vehicle is the assisted driving state or the manual driving state, all data acquisition devices of the vehicle data acquisition system are turned off.

[0041] Because when the vehicle is driving, if it is in a driver-led driving state (i.e. assisted driving state and manual driving state), the road condition data collected by the data acquisition equipment will have little impact on driving safety in the short period of time when the vehicle passes through a specific area. At this time, all data acquisition devices of the vehicle data acquisition system can be directly turned off to maximize the protection of information security in the specific area.

[0042] Figure 2 1 is a flow chart of a control method of a vehicle data collection system provided by another exemplary embodiment of the present application. The control method of the vehicle data collection system is applied to a fixed end in the vehicle data collection system. The vehicle data collection system includes a vehicle-mounted end arranged on a vehicle and a fixed end arranged in a specific area. When the vehicle-mounted end enters a preset range of the fixed end, the vehicle-mounted end and the fixed end establish a communication connection; Figure 2 As shown, the control method of the vehicle data acquisition system includes the following steps:

[0043] Step 210: Identify vehicles that enter a preset range of the fixed end.

[0044] Specifically, the present application uses a fixed terminal to check and identify vehicles entering a preset range (i.e., a specific area) of the fixed terminal in real time, so that when a vehicle and its vehicle-mounted terminal enter the preset range of the fixed terminal, the corresponding vehicle information can be discovered and identified in time.

[0045] Step 220: Send a transmission signal to the vehicle-mounted terminal of the vehicle to shut down part or all of the data acquisition devices of the vehicle data acquisition system.

[0046] The transmission signal is a wireless signal transmitted from the fixed end to a preset range of the fixed end. After determining the vehicle information entering the specific area, the signal transmitter set at the fixed end sends a transmission signal to the signal receiver of the vehicle-mounted end corresponding to the vehicle information to inform the vehicle-mounted end that the vehicle has entered the specific area. At this time, the vehicle-mounted end receives the transmission signal and shuts down part or all of the data collection equipment of the vehicle data collection system based on the transmission signal to prevent information leakage caused by the data collection equipment collecting relevant data of the specific area.

[0047] A control method for a vehicle data acquisition system provided in the present application is applied to a fixed end in the vehicle data acquisition system, wherein the vehicle data acquisition system includes an on-board end arranged on a vehicle and a fixed end arranged in a specific area, wherein when the on-board end enters a preset range of the fixed end, the on-board end and the fixed end establish a communication connection, the fixed end identifies the vehicle entering the preset range of the fixed end, and sends a transmission signal to the on-board end of the vehicle to shut down part or all of the data acquisition equipment of the vehicle data acquisition system, wherein the transmission signal is a wireless signal transmitted from the fixed end to the preset range of the fixed end; that is, by setting a fixed end in a specific area to identify the vehicle entering the preset range of the fixed end, transmitting information is sent to the on-board end when a vehicle is identified to have entered, and the on-board end shuts down part or all of the data acquisition equipment to stop acquisition after receiving the transmission signal, thereby effectively preventing information leakage in a specific area.

[0048] In one embodiment, the vehicle-mounted end includes an information tag, which contains the identity information of the vehicle, and the fixed end includes a reading device for identifying the information tag; wherein, the specific implementation method of the above step 210 may be: using the reading device to identify the identity information in the information tag; correspondingly, the specific implementation method of the above step 220 may be: based on the identified identity information, sending a transmission signal to the corresponding vehicle-mounted end.

[0049] Specifically, the present application sets a reader of a short-range wireless communication system (such as an RFID system) at the fixed end, and sets a tag of the short-range wireless communication system at the vehicle-mounted end. When the vehicle and its vehicle-mounted end enter the preset range of the fixed end, the reader at the fixed end will read the tag signal of the vehicle-mounted end, wherein the tag contains the vehicle's unique identification code (identity information). The reader reads the tag at the vehicle-mounted end and determines the vehicle information entering the specific area based on the unique identification code in the tag. The fixed end sends a transmission signal to the vehicle-mounted end corresponding to the unique identification code to inform the vehicle-mounted end that the vehicle has entered the specific area. The vehicle-mounted end receives the transmission signal and shuts down part or all of the data acquisition equipment of the vehicle data acquisition system based on the transmission signal to prevent information leakage caused by the data acquisition equipment collecting relevant data of the specific area.

[0051] The present application provides a control device for a vehicle data acquisition system, which is arranged at a vehicle-mounted terminal in the vehicle data acquisition system. The vehicle data acquisition system includes a vehicle-mounted terminal arranged on the vehicle and a fixed terminal arranged in a specific area. When the vehicle-mounted terminal enters a preset range of the fixed terminal, the vehicle-mounted terminal and the fixed terminal establish a communication connection; a transmission signal receiving module 31 of the vehicle-mounted terminal receives a transmission signal sent by the fixed terminal, wherein the transmission signal is a wireless signal transmitted from the fixed terminal to a preset range of the fixed terminal, and a working mode acquisition module 32 acquires the working mode of the vehicle data acquisition system. If the working mode is a data acquisition state, a collection device control module 33 turns off part or all of the data acquisition devices of the vehicle data acquisition system; that is, by setting a fixed terminal in a specific area, when a vehicle enters, transmission information is sent to the vehicle-mounted terminal, and after receiving the transmission signal, the vehicle-mounted terminal checks the working mode of the vehicle data acquisition system. If the data acquisition device is in a data acquisition state at this time, part or all of the data acquisition devices are turned off to stop acquisition, thereby effectively preventing information leakage in a specific area.
