[0002] Currently, before a vehicle leaves the factory, it is usually necessary to conduct on-site scenario tests on the vehicle's performance. Specifically, in the test site, the driver receives each test task on the test task list of the vehicle to be tested through a walkie-talkie device to control the vehicle to drive in the test site.
[0003] Generally, the vehicle is an unlicensed vehicle. Before the test, the global testing equipment will assign a global ID to the vehicle to identify the vehicle's identity information. After that, during the test process, the global testing equipment will track the vehicle in real time and generate trajectory information including the global ID and the trajectory position. Then, after the test is completed, all the global trajectories corresponding to the trajectory positions will be bound to the vehicle according to the global ID.
[0004] However, in actual situations, since the test scenario may include multiple vehicles. When tracking a certain vehicle, the global testing equipment may experience tracking loss. At this time, after a period of loss, when the vehicle is detected again, the global testing equipment will assign a new global ID to the vehicle and generate the above-mentioned trajectory information. At this time, since the global ID is a new global ID, the global trajectory included in the newly generated trajectory information will not be able to correspond to the previous vehicle.
[0005] Based on this, after the vehicle to be tested completes the test, the global trajectory perceived by the global testing equipment will not be able to correspond to the identity information of the actual vehicle to be tested, reducing the test effect. Summary of the Invention

[0030] Currently, before a vehicle leaves the factory, it is usually necessary to conduct on-site scenario tests on the vehicle's performance. Specifically, in the test site, the driver receives each test task on the test task list of the vehicle to be tested through a walkie-talkie device to control the vehicle to drive in the test site.
[0031] Generally, the vehicle is an unlicensed vehicle. Before the test, the global test device will assign a global ID to the vehicle to identify the vehicle's identity information. After that, during the test process, the global test device will track the vehicle's trajectory in real time and generate trajectory information including the global ID and the trajectory position. Then, after the test is completed, all the global trajectories corresponding to the trajectory positions will be bound to the vehicle according to the global ID.
[0032] However, in the actual process, since the test scenario may include multiple vehicles. When tracking a certain vehicle, the global test device may experience tracking loss. At this time, after a period of loss, when the vehicle is detected again, the global test device will assign a new global ID to the vehicle and generate the above-mentioned trajectory information. At this time, since the global ID is a new global ID, the global trajectory included in the newly generated trajectory information will not be able to correspond to the previous vehicle. As a result, at the exit of the test site, the central platform cannot associate the new global ID and global trajectory with the test task list at this time, reducing the test effect.
[0033] Based on this, in order to make the global trajectory perceived by the global test device correspond to the identity information of the actual vehicle to be tested and improve the test effect of subsequent test analysis based on the accurate global trajectory, an embodiment of the present application provides a vehicle test method, which is applied to the global test device.
[0034] Among them, the global test device can be a roadside perception device built in the test site, which is used to perceive the test trajectories of various vehicles in the test site and perform target tracking. Among them, when performing tracking, a global ID needs to be assigned to the vehicle to be tested.
[0035] In one embodiment, testing the vehicle to be tested includes, but is not limited to, intelligent path planning testing, automatic obstacle avoidance testing, and billing testing, and this is not limited.
[0036] Exemplarily, the billing test can be to record the entry time and exit time of the vehicle to be tested when entering and leaving the test site. Then, billing is performed according to the entry time and exit time. Among them, the global trajectory of the vehicle to be tested in the test site needs to be determined according to the vehicle test method in this embodiment.
[0037] Please refer to Figure 1 , Figure 1 which shows the implementation flowchart of a vehicle test method provided by an embodiment of the present application. The method includes the following steps:
[0038] S101. Obtain the binding relationship between the global ID of the vehicle to be tested, the first ID of the ETC-OBU device, and the second ID of the walkie-talkie device; the ETC-OBU device is strongly bound to the vehicle, the first ID is used to identify the identity information of the vehicle, and the walkie-talkie device is used to receive test tasks to instruct the tester to test the vehicle to be tested.
[0039] In one embodiment, the above global ID is the global ID assigned to the vehicle to be tested when the global test device perceives the global trajectory of the vehicle to be tested, and is used to identify each first position of the perceived vehicle to be tested. The above ETC-OBU device is an ETC on-vehicle unit, which is used to communicate with a roadside unit (RSU) through dedicated short range communication (DSRC) technology. Furthermore, the billing function of the vehicle to be tested can be simulated and tested.
[0040] Among them, an ETC-OBU device can insert an ETC card, and vehicle identity information is written on the ETC card. Moreover, the ETC-OBU device can be set on the vehicle to utilize the anti-disassembly feature of the ETC device and the strong binding with the vehicle to avoid malicious loss of vehicle identity information during the testing process. In this embodiment, the above identity information can be characterized by a first ID. The first ID can be a number, a letter, or a combination thereof, and there is no limitation thereto.
[0041] Among them, the ETC-OBU device can be pasted on the front windshield of the vehicle to be tested or at the position of the side mirror, and there is no limitation thereto.
[0042] The above walkie-talkie device can be a device with positioning function and a second ID. Before the test, the tester can bind the second ID of the walkie-talkie device to the test task. During the test, the walkie-talkie device can receive the pre-bound test task to instruct the person to be tested to test the vehicle to be tested.
[0043] Moreover, because the walkie-talkie device has a positioning function, the vehicle to be tested can upload the positioning trajectory information of the vehicle to be tested during the test.
[0044] Among them, to ensure that the global trajectory corresponds to the identity information of the vehicle to be tested, before the test, the global test device needs to establish the binding relationship among the above global ID, first ID, and second ID.
[0045] Specifically, the global test device can establish the above binding relationship according to the steps S201-S204 as shown in Figure 2 shown below. Details are as follows:
[0046] S201. Broadcast a wake-up signal at the entrance of the test site and receive the first ID sent by the ETC-OBU device based on the wake-up signal; the wake-up signal is used to wake up the ETC-OUB device of the vehicle to be tested at the entrance and establish a communication connection with the ETC-OUB device.
[0047] Among them, the global test device can include an ETC device, which is set at the entrance and exit of the test site. Among them, the ETC device is an electronic toll collection system, which is mainly applicable to highway or busy bridge and tunnel scenarios.
[0048] In this embodiment, the ETC device can usually broadcast a wake-up signal in real time or at preset intervals to wake up the ETC-OBU device in the vehicle to be tested and establish a communication connection with it. At this time, the ETC-OBU device can upload the identity information written on the ETC card to the ETC device. Among them, the above-mentioned identity information has been described as the first ID, so it can be considered that the first ID is uploaded to the ETC device.
[0049] S202. Obtain the initial global trajectory information of the vehicle to be tested at the entrance; the initial global trajectory information includes the initial first position and the global ID assigned to the vehicle to be tested.
[0050] In one embodiment, the above-mentioned global ID has been described in S101 and will not be described again here. It should be noted that the above-mentioned initial first position is the position before the global test device senses that the vehicle to be tested has not entered the test site. Among them, the global test device may include a radar sensing device for sensing the position of the vehicle to be tested (including the initial first position and the first position in the following steps).
[0051] It should be noted that after the global ID is assigned to the vehicle to be tested, the global sensing device can bind the global ID and the first ID obtained in step S201.
[0052] S203. Obtain the initial positioning trajectory information uploaded by the walkie-talkie device, where the initial positioning trajectory information includes the initial second position and the second ID.
[0053] S204. Establish a binding relationship according to the initial first position and the initial second position.
[0054] In one embodiment, the above-mentioned second ID has been described in the above S101 and will not be described again here. Among them, the above-mentioned initial second position is the position uploaded by the walkie-talkie device.
[0055] It can be understood that when the second position should be consistent with the first position sensed by the global test device, or the distance between the two is less than the first preset distance, it can be considered that the walkie-talkie device is located on the vehicle to be tested assigned with the global ID. At this time, the global test device can also bind the second ID and the global ID. Among them, the first preset distance can be set by the tester according to the actual situation and is not limited here.
[0056] Based on the above description, it can be seen that before each vehicle to be tested undergoes testing, it can communicate with the global test device at the entrance, and then obtain the first ID that is strongly bound to the vehicle to be tested in advance. Moreover, the global test device can also sense the first position of the vehicle to be tested at the entrance of the test site and assign a global ID to it. Therefore, the global test device can also bind the global ID and the first ID.
[0057] At the same time, the global sensing device can also receive the second position of the vehicle to be tested uploaded by the walkie-talkie device at the entrance of the test site. It can be understood that when the distance between the first position and the second position is less than the first preset distance, it can be considered that the walkie-talkie device uploaded this time should be located on the vehicle to be tested corresponding to the global ID. Therefore, the global ID and the second ID of the walkie-talkie device can be bound.
[0058] Based on this, based on the above-mentioned bound global ID and the first ID, at this time, before the vehicle to be tested is tested, the global test device can bind the global ID, the first ID, and the second ID in three parties to generate the above-mentioned binding relationship.
[0059] S102. Obtain the first global trajectory information of the vehicle to be tested; the first global trajectory information includes the first position and the global ID.
[0060] S103. Obtain the positioning trajectory information uploaded by the walkie-talkie device; the positioning trajectory information includes the second position and the second ID.
[0061] In one embodiment, both the above-mentioned first global trajectory information and the positioning trajectory information are the trajectory information obtained after the vehicle to be tested enters the test site. Among them, the first global trajectory information can not only include the first position and the global ID, but also include the first time when the first position is obtained. And, the positioning trajectory information can not only include the second position and the second ID, but also include the second time when the second position is obtained.
[0062] It should be noted that there may be a perception blind area of the global test device in the test site, resulting in the loss of the first position of the vehicle to be tested during the test process. Furthermore, when the vehicle to be tested is re-perceived, a new global ID is assigned by the global test device. However, the new global ID is not bound to the first ID and the second ID. Therefore, at the exit of the test site, the global trajectory corresponding to the new global ID cannot be associated with the identity information of the vehicle to be tested. Based on this, the following S104 step needs to be executed.
[0063] S104. According to the binding relationship and the positioning trajectory information, perform dot-filling matching on the first position in the first global trajectory information to obtain the second global trajectory information; the second global trajectory information includes at least the first position after dot-filling matching and the first ID.
[0064] In one embodiment, the above-mentioned dot-filling matching of the first position includes, when the first position is not missing, matching the first ID representing the identity information to the first global trajectory. When the first position is missing, supplement the missing first position in the first global trajectory information according to the second position in the positioning trajectory information, and match the first ID to the first global trajectory. At this time, in the second global trajectory information after dot-filling matching, it will include the global trajectory formed by the non-missing first position and the first ID representing the identity information of the vehicle to be tested.
[0065] Specifically, the global test device can obtain the first global trajectory information of the vehicle to be tested in real time or at preset intervals. At this time, each time the first global trajectory information is obtained, the global test device can add the first ID corresponding to the global ID to the first global trajectory information according to the binding relationship obtained in S101 to obtain the second global trajectory information. Based on this, the second global trajectory information will include the first position, the global ID, and the first ID.
[0066] Moreover, if the first global trajectory information is not obtained, it can be considered that the global test device has lost the position information of the vehicle to be tested at this time. At this time, the global test device can obtain the target second position in the positioning trajectory information at the same moment according to the binding relationship. Then, the target second position is determined as the missing first position, and the first ID associated with the global ID is added to the first global trajectory information according to the binding relationship to obtain the second global trajectory information.
[0067] Exemplarily, the global test trajectory can determine the target second position as the missing first position according to the binding relationship and add the first ID to the first global trajectory information. The second global trajectory information generated at this time still includes the first position (target second position) and the first ID.
[0068] Based on this, it can be determined that when the vehicle to be tested is in the sensing blind area of the radar sensing device, the finally generated second global trajectory information can still match the corresponding vehicle to be tested based on the first ID.
[0069] In another embodiment, when the vehicle to be tested drives out of the sensing blind area of the global test device and is sensed by the global test device again, the global test device will reassign a new global ID to the vehicle to be tested. At this time, the first global trajectory information generated subsequently will be the first position and the new global ID.
[0070] Based on this, in order to match the first global trajectory information generated subsequently with the corresponding vehicle to be tested, the global test device can obtain the second position and the second ID uploaded by the walkie-talkie device of each vehicle to be tested at the same time when obtaining the first position and the new global ID. Then, calculate the interval distance between the first position and each second position respectively, and correspond the second ID corresponding to the minimum interval distance to the new global ID. Finally, based on the binding relationship, determine the first ID originally bound to the second ID corresponding to the minimum interval distance, so as to replace the new first ID with the originally bound first ID, and associate the new first global trajectory information with the first global trajectory information corresponding to the first ID originally bound, to realize the retrieval of the first global trajectory information.
[0071] Among them, the method of determining the first global trajectory information that matches according to the first position and the second position is only one of the examples. In another embodiment, it is also possible to obtain the new first global trajectory information and the positioning trajectory information uploaded by each intercom device within a period of time. Then, the new first global trajectory information within a period of time is matched with each positioning trajectory information to determine the second ID corresponding to the new global ID. Furthermore, through the trajectory matching within a period of time, the matching accuracy can be improved. In this embodiment, the method of determining the second ID corresponding to the new global ID is not limited.
[0072] It should be particularly supplemented that when performing supplementary point matching, the global ID, the first ID, and the second ID can also be supplemented into the first global trajectory information based on the binding relationship. At this time, each first position after supplementary point matching in the obtained second global trajectory information will include the global ID, the first ID, and the second ID to fully bind the first position to the vehicle identity information, and this is not limited.
[0073] It should be supplemented that if only the positioning trajectory information uploaded by the intercom device is used as the trajectory information of the vehicle to be tested, there will be a situation where the intercom device is lost during the actual test. At this time, if only the positioning trajectory information of the intercom device is used as the trajectory information of the vehicle to be tested, there will be a problem that the positioning trajectory information does not belong to the true trajectory information of the vehicle to be tested. Based on this, by using the dual methods of strongly binding the ETC-OBU device to the vehicle to be tested and the intercom device to the vehicle to be tested, on the basis of ensuring the continuity of the global trajectory during the test of the vehicle to be tested, the global trajectory can accurately correspond to the identity information of the vehicle to be tested.
[0074] In this embodiment, before the test, an ETC-OBU device with a strong binding connection can be pre-set for the vehicle to be tested, and the first ID of the ETC-OBU device can be identified. Also, a walkie-talkie device with a weak binding connection can be set for the vehicle to be tested, and the second ID of the walkie-talkie device can be identified. Furthermore, the association relationship among the global ID, the first ID, and the second ID assigned by the global test device when tracking the global trajectory of the vehicle to be tested can be established. During the test, the global test device perceives the first global trajectory information of the vehicle to be tested in real time and obtains the positioning trajectory information uploaded by the walkie-talkie device. Then, for the first position in the first global trajectory information, when the first position is not lost, the first ID can be written into the first global trajectory information based on the binding relationship to match the first ID with the first position. And when the first position is lost, the first position lost in the first global trajectory information can be supplemented based on the binding relationship and the second position in the positioning trajectory information. At the same time, the ID can also be written into the first global trajectory information based on the binding relationship to match the first ID with the first position after the missing point is filled. Based on this, in the generated second global trajectory information, each first position after the missing point is filled will have the first ID that can identify the vehicle identity information. Furthermore, even when the global test device loses track during the test of the vehicle to be tested, a complete global trajectory of the vehicle to be tested can be generated, and the global trajectory can be corresponding to the identity information of the vehicle to be tested, improving the test effect.
[0075] In another embodiment, during the test, the walkie-talkie device may be maliciously exchanged or lost. At this time, the tester in the vehicle to be tested may not receive the test task, or may receive the test tasks of other vehicles to be tested based on the exchanged walkie-talkie device, resulting in the test tasks actually completed by the vehicle to be tested not corresponding to the test task list pre-associated with the walkie-talkie device.
[0076] Based on this, in order to make the vehicle to be tested correspond to the test task list, the global test device can also calculate the distance between the first position and the second position at the same moment. After that, when the distance between the two positions is greater than the second preset distance, it can be considered that there is a relatively large interval distance between the second position where the vehicle to be tested is located uploaded by the walkie-talkie device and the first position where the vehicle to be tested is perceived by the global test device. Furthermore, the global test device can determine that the walkie-talkie device is not on the vehicle to be tested. Therefore, the global test device can generate a prompt message to remind the tester that the walkie-talkie device is lost. And the global trajectory device can also terminate the test of the vehicle to be tested this time.
[0077] It should be noted that the global ID corresponding to the above first position should have a binding relationship with the second ID corresponding to the second position. The above second preset distance can be set by the tester according to the actual situation, and it can be equal to the first preset distance, and there is no limitation on this.
[0078] It should be added that when the distance between the first position and the second position is less than the second preset distance, it can be considered that the intercom device is on the vehicle to be tested during the test process. Therefore, it can be determined that all the test tasks received by the vehicle to be tested during the test process are the test tasks that actually need to be tested. Based on this, after the test of the vehicle to be tested is completed, the global trajectory device also associates the second global trajectory information, the test task sheet of the vehicle to be tested, and the first ID according to the binding relationship.
[0079] Among them, the above test task sheet can be pre-associated with the intercom device so that after the test, the test task sheet can correspond one-to-one with the identity information and the global trajectory of the corresponding vehicle to be tested.
[0080] In another embodiment, referring to Figure 3 , Figure 3 is a schematic diagram of an application scenario of D in a vehicle test method provided by an embodiment of the present application. When the test task sheet is an ETC charging test task sheet, before the vehicle to be tested is tested, an ETC-OBU device can be installed on the front windshield of the vehicle to be tested, and an ETC card with the vehicle identity information (for example, the first ID) written on it can be inserted into the ETC-OBU device. Furthermore, the anti-tampering feature of the ETC device can be utilized to avoid malicious loss of vehicle identity during the test process.
[0081] Moreover, the tester can obtain an intercom device with a positioning function and a second ID, and associate the second ID with the ETC charging test task sheet. Among them, during the test process, the intercom device may be maliciously exchanged. And, the intercom device can receive each test task in the ETC charging test task sheet in real time, and upload the second position and the second ID.
[0082] Then, when the vehicle to be tested reaches the entrance of the test site, since a gantry ETC device is set at the entrance of the test site, it can communicate with the ETC-OBU device. Therefore, the global test device can obtain the first ID of the vehicle to be tested and record the start time of entering the test site. And, the global test device can also sense the initial first position and the global ID of the vehicle to be tested. Furthermore, the global ID is bound to the first ID. At the same time, the global test device can also receive the second ID and the initial second position uploaded by the intercom device, so as to bind the global ID and the second ID based on the initial first position and the initial second position. Based on this, at the entrance, the global test device can complete the three-party binding relationship among the global ID, the first ID, and the second ID.
[0083] After that, during the testing process, for each piece of acquired first global trajectory information, it can include a first position, a first time, and a global ID. Also, for each piece of acquired positioning trajectory information, it can include a second position, a second time, and a second ID. Then, when the first position is not lost, the global testing device can write the second ID at the same time (the first time and the second time are the same), and the first ID with a binding relationship into the first global trajectory information to obtain the second global trajectory information. At this time, the second global trajectory information will include the first position, the first time, the global ID, the first ID, and the second ID.
[0084] Also, when the first position is lost, the global testing device can determine the first time of the lost first position, and then write the target second position and the second ID with a binding relationship and at the same time, and the first ID with a binding relationship with the second ID into the first global trajectory information to obtain the second global trajectory information. At this time, the second global trajectory information will also include the target second position (the first position after filling point matching), the first time, the global ID, the first ID, and the second ID.
[0085] After the testing is completed, the global testing device can also obtain the end time of the vehicle to be tested based on the gantry ETC device at the exit.
