[0003] Automatic Emergency Braking Systems (AEBS) is one of the systems that improve the safety of cars. A series of verifications are performed on the automatic emergency braking system before installation to the vehicle to ensure that it is braked when needed and the misoperation rate is within a certain range.

[0004] Currently, AEBS verification is performed during project implementation prior to vehicle assembly. Specifically, the simulation system simulates a large amount of pre-collected driving data, and records the number of times the AEBS takes emergency braking, and determines whether the number is within the required AEBS misoperation range. If yes, the verification passes, otherwise, the re-adjustment The parameters are simulated again until the erroneous range of emergency braking by the AEBS is within the allowable range.

[0005] The automatic emergency braking system itself is very sensitive to the environment. For example, a slightly different location of the radar installation, a slightly different radar damper material, or a slightly different shape of the entire radar sensor can result in differences in the radar sensor sensing data.

BRIEF DESCRIPTION OF THE DRAWINGS [0022] Illustrative examples of the invention are now described with reference to the drawings, in which The embodiments described below are intended to provide a thorough understanding of the invention, and are intended to The illustrations of the components, components, modules, devices, and device bodies in the figures are not necessarily drawn to scale, and are merely illustrative of the relative relationship between the components, components, modules, devices, and device bodies.

1 is a schematic view of a general AEBS structure. As shown, the AEBS includes a sensor 10 and a controller 12. The sensor 10 is disposed at the front of the vehicle body for detecting information of a vehicle located in front of the vehicle (hereinafter also referred to as the vehicle) during running of the vehicle, and the information may include a distance from the front vehicle, a vehicle speed of the preceding vehicle, and the like. The information of the vehicle ahead is referred to as the preceding vehicle information. The controller 12 is electrically connected to the sensor 10 and receives the vehicle information detected by the sensor 10. In some implementations, controller 12 is disposed in sensor 10 as part of sensor 10 Inside. The controller 12 is also electrically connected to the electronic control unit (ECU) of the vehicle to obtain information about the current vehicle speed of the vehicle, whether the driver is stepping on the brakes, and the related components, such as the electronic stability system of the vehicle (ESP). ) Issue an emergency brake command to brake the vehicle urgently. In general, the controller 12 is also electrically coupled to the vehicle meter display device for displaying information such as distance from the preceding vehicle. It is to be noted that the sensor 10 can be disposed at a position other than the front portion of the vehicle body, and in some cases, the sensor 10 can also sense information of the vehicle at a position other than the front of the vehicle.

[0024] The sensor 10 transmits the detected forward vehicle information to the controller 12. Based on the vehicle information in front (as described above, the information includes the distance of the preceding vehicle from the vehicle, the speed of the vehicle ahead, etc.) and the current vehicle speed of the vehicle, the controller 12 can calculate how long the vehicle collides with the preceding vehicle; The controller 12 determines whether the driver takes the brake based on the information communicated by the ECU. The controller 12 has preset parameters related to the automatic braking in an emergency, and the controller 12 determines, based on these parameters, when to take the brake at the current vehicle speed, the distance to the preceding vehicle, and the current road condition. If the driver has not taken the brake at the time determined by the controller 12, an emergency braking command is issued to the brake system to take emergency braking. In the AEBS system, the sensor 10 may be a radar sensor or other type of sensor that can detect an obstacle such as a vehicle in front.

[0025] As with most automotive systems, the AEBS system is rigorously verified before it is officially applied to the vehicle. As described in the background section, conventional AEBS verification is performed during the project implementation phase prior to assembly of the vehicle. This verification method prolongs the verification cycle and correspondingly increases the verification cost.

2 illustrates a flow chart of a verification method for verifying an automatic emergency braking system for obtaining desired parameter settings available for an AEBS system, in accordance with one embodiment of the present invention. By way of example and not limitation, the execution of the method illustrated in Figure 2 may be performed by a verification system for an automatic emergency braking system in accordance with the present invention. Figure 3 is a block diagram showing the structure of a verification system for an automatic emergency braking system in accordance with the present invention. The verification system shown in FIG. 3 includes a load module 30, a collection module 32, and an analysis module 34. During the verification of the AEBS, the verification system is electrically connected to the AEBS so that data interaction can be performed between the two. Briefly, in the verification system, the loading module 30 loads the parameter set into the AEBS, the collecting module 32 collects the data of the AEBS simulated braking based on the loaded parameters, and the analysis module 34 analyzes the data according to the collected data. Simulate the braking situation to obtain a parameter set that causes the AEBS to meet the preset conditions. The analysis module 34 and the collection module 30 can communicate directly or indirectly. Direct communication refers to communication between the analysis module 34 and the collection module 30 directly through wireless transmission or wired transmission. For example, the analysis module 34 directly acquires the collected data from the collection module 30 in a wireless or wired transmission manner. Indirect communication means that both the analysis module 34 and the collection module 30 communicate via an intermediate module or component. For example, the collection module 30, which will be mentioned later, first transmits the collected data to an electronic device of a service organization such as a 4S store, and then The data is transmitted by the electronic device to the central control room The database, and the analysis module 34 obtains data from the database for analysis. The verification system shown in Figure 3 can be implemented as a software module or hardware or a combination of the two. The loading module 30 and the collection module 32 can be incorporated into a verified automatic emergency braking system, and the analysis module 34 can be additionally disposed, for example, in a data processing device within a central control room, such as a computer. In addition, analysis module 34 can communicate with load module 30 to communicate the adjusted set of parameters to load module 30 as needed, for loading the adjusted set of parameters into the AEBS. Similarly, the analysis module 34 and the loading module 30 may be directly communicated or indirectly communicated.

[0027] Hereinafter, an authentication method and a verification system for an automatic emergency braking system according to the present invention will be described by way of example with reference to FIGS. 2 and 3.

[0028] At step 20, a parameter set is loaded into an automatic emergency braking system of each vehicle, wherein the parameter set described herein includes at least a first parameter set for conservative braking and a second parameter set for moderate braking. One of the parameter group and the third parameter set for early braking, and each vehicle loads only one parameter group. In the examples described herein below, the parameters include a first parameter set, a second parameter set, and a third parameter set. The parameters of each parameter group include road condition information and time parameters for braking. The initial selection and value of the specific parameters in the parameter group can be selected or set according to experience. In the other case, the parameters in the parameter group are adjusted in the following step 24, which will be described below. Conservative braking means that the set AEBS starts braking time is later than the braking time required by the new car crash test standard; moderate braking means the set AEBS start braking time and the braking time required by the new car crash test standard Consistent; Early braking means that the set AEBS starts braking earlier than the braking time required for the new car crash test.

[0029] Conservative braking, moderate braking, and early braking are further illustrated in conjunction with FIG. 2a. As shown in FIG. 2a, it is assumed that the sensor 100 is disposed at a certain position of the head of the vehicle A1 - Car 101 traveling at a certain speed, and the vehicle A1 - Car 101 is traveling, and the sensor 100 detects the vehicle B at a certain distance in front. — Car 102.

[0030] In this hypothetical case, the moderate braking refers to: According to the current A1 - Car 101 and B-Car 102 speed, the distance between the two cars and the current road conditions and according to the relevant requirements of the new car collision standard (assuming a new car) The collision criteria require that in this case, the vehicle A1—Car 101 should be braked when it encounters the B-Car 102 after the T period, and if it will hit the B-Car 102 after the T period, the vehicle A1— If the driver of the Car 101 has not taken any braking measures, the emergency braking system must take emergency braking. For moderate braking, the AEBS should be braked when the A1—Car 101 will encounter the B-Car 102 after the T period and the driver of the A1-Car 101 has not taken the braking action. Accordingly, the second parameter set for moderate braking includes the road condition parameter, the time parameter for taking emergency braking (T in this example), and the like.

[0031] Under the same assumption, the conservative braking refers to: Compared with the moderate braking as described above, the AEBS is required to approach the vehicle B-Car 102 in front of the vehicle A1 - Car 101, ie the vehicle A1 - Car In the case where the B-Car 102 is to be hit in a shorter period of time than T, the brake is taken if the driver does not take the brake. Obviously conservative braking, AEBS The time to start braking is later than the time required to take the brakes according to the requirements of the new car collision standard. It is not difficult to understand that the time required for the brakes to brake the AEBS is more demanding. The first parameter group for conservative braking also includes the road condition parameter, the time parameter for taking emergency braking (the time period corresponding to the time parameter is less than T in this example), and the like.

[0032] Still under the same assumptions, the early braking refers to: AEBS is required to be farther away from the vehicle B-Car 102 ahead of the vehicle A1 - Car 101 than the moderate braking as described above (also It is better than the distance between the two cars when the AEBS is braking when the brake is moderate), that is, the time when the vehicle A1—Car 101 will hit the B-Car 102 for a certain period of time longer than T, if the driver does not take When braking, take the brake. Obviously, in the early braking, the AEBS starts to brake longer than the AEBS takes the brakes according to the requirements of the new car collision standard. The third parameter group for early braking also includes the road condition parameter, the time parameter for taking emergency braking (the time period corresponding to the time parameter is greater than T in this example), and the like.

[0033] Returning to step 20, the parameter sets are respectively loaded into the AEBS system of different vehicles by the parameter setting module 30, which are vehicles participating in fleet validation or different end customers participating in the verification. Vehicle; wherein, only one parameter group is set in each vehicle. For example, a first parameter set for conservative braking is loaded into the AEBS, W, of each of the first group of vehicles, each of which is provided with a first parameter set in the AEBS system; The second parameter set of moderate braking is loaded into the AEBS, BP of the second group of vehicles, and each of the second group of vehicles is provided with a second parameter set in the AEBS system; The third parameter group is then loaded into the third group of vehicles, that is, each of the third group of vehicles, the third parameter group is set in the AEBS system. The AEBS system in which the parameter group is loaded will perform analog braking according to this parameter.

[0034] The parameter set set in step 20 may include multiple sets, not the first parameter set for conservative braking, the second parameter set for moderate braking, and for early braking. The third parameter group is limited. For example, for conservative braking, two or more sets of parameters can be set. For early braking, two or more parameter sets can also be set. In all of the examples in this article, only one parameter group is set for both conservative braking and early braking.

[0035] In the present application, the automatic emergency braking system under simulated braking is different from the automatic emergency braking system in normal operating conditions only in that the former does not actually send a braking command to the braking system. In other words, the AEBS in the verification phase performs an analog braking in the event that emergency braking is required to verify that the system is aware that the AEBS should take emergency braking, but the simulated braking command does not act on the vehicle's braking system. In addition, the driving verification refers to the verification process of the overall performance verification of the ECU when the ECU is designed and the vehicle assembly of the ECU is completed and not in the sales stage.

[0036] At step 22, each of the first group of vehicles, the second group of vehicles, and the third group of vehicles, during the running thereof, the collection module 32 of the verification system collects braking data related to the AEBS simulated braking . The collection module 32 can be disposed at The sensor 10 of the AEBS shown in Fig. 1 is provided, for example, in a radar sensor. To ensure the accuracy of the verification, sufficient data should be collected for subsequent analysis. To this end, vehicles carrying any of the parameter sets need to travel, for example, at a distance of approximately 100,000 kilometers. During the driving process of about 100,000 kilometers, the collecting module 32 provided in each vehicle collects the braking data of the AEBS simulated braking, for example, including: the number of simulated braking; the road surface condition, such as the road surface for the highway, the rural dirt road or Ordinary roads, etc.; and data related to the basic environment of the vehicle, such as vehicle dynamics data. Alternatively, the collection of data relating to road conditions and the basic environment associated with the vehicle may be ongoing during vehicle travel or only when AEBS simulated braking occurs.

[0037] At step 24, based on the data collected by the collection module 32, the analysis module 34 analyzes the simulated braking conditions to obtain a set of parameters that cause the simulated braking of the automatic emergency braking system to meet predetermined conditions. The analysis module 34 can be set up in the central control room. The data collected by each vehicle can be transmitted from the vehicle to the database of the central control room for analysis module 34 to analyze based on the data stored in the database. The collected data can be transmitted from the vehicle to the database in the central control room in any of the following cases: When the vehicle goes to a service organization such as a 4S shop for maintenance, the data collected on the vehicle is first passed through a transmission line (such as a USB transmission line, etc.). Or wireless transmission (such as WiFi or Bluetooth transmission, etc.) is transmitted to the electronic device of the service organization, and then transmitted to the database of the central control room via the network via the electronic device; or the data collected on the vehicle is first transmitted through the transmission line (for example) USB transmission line, etc.) or wireless transmission (such as WiFi or Bluetooth transmission, etc.) is transmitted to the smartphone, which is then transmitted to the database of the central control room. In addition, if the vehicle is loaded with CAN-TCP/IP (CAN bus protocol to TCP/IP protocol) converter, and the relevant data of the system including AEBS in the vehicle is data conforming to the CAN bus, the conversion can be performed by the conversion. The data is converted to TCP/IP protocol data for transmission over the network directly from each vehicle to a database of the central control room for use by the analysis module 34 or directly to the analysis module 34.

[0038] In the analysis, based on the collected data, the analysis module 34 analyzes the simulated braking condition of the automatic emergency braking system loaded with each parameter group, and simulates the automatic emergency braking system associated with any parameter group. When the preset condition is met, the parameter group can be determined as a parameter group that satisfies the preset condition, so that the parameter group can be applied to the AEBS as a final parameter, and the verification can be ended. More specifically, if the recorded brake data corresponding to any parameter group indicates that the brake condition exhibited by the analog brake of the AEBS loaded with the parameter group satisfies the preset requirement for the AEBS brake, that is, the preset Condition, the parameters of the parameter group can be set to the final AEBS parameter group. For the analysis process, the AEBS simulated braking data recorded and transmitted by the first group of vehicles can be separately analyzed, that is, the automatic emergency braking system associated with the first parameter group (ie, the conservative braking parameter group) is analyzed. Simulated braking situation; analysis of the AEBS simulated braking data recorded and transmitted by the second group of vehicles, ie the simulation of the automatic emergency braking system associated with the second parameter group (ie the moderate braking parameter group) Analysis of the AEBS simulated brake data recorded and transmitted by the third group of vehicles, ie analysis and analysis The simulated braking condition of the automatic emergency braking system associated with the third parameter group (ie, the early braking parameter group).

[0039] Conversely, if the above analysis does not obtain a parameter group that satisfies the preset condition, the analysis module 34 may adjust the parameters of each parameter group according to the analysis result, and transmit the adjusted parameter group to the loading module 30, thereby again Perform steps 20, 22, and 24 until you get the parameter set that matches the simulated brake of the AEBS to the preset conditions. In the case where, for example, a CAN-TCP/IP converter is provided in the vehicle, the adjusted parameters can be transmitted to the load module 30 through the CAN-TCP/IP converter. In addition, since with the CAN-TCP/IP converter, the central control room can obtain the simulated braking data directly from the collection module of the verification system without the electronic equipment of the service organization such as the 4S shop. Continuously monitor the performance of AEBS during vehicle travel.

[0040] Here, the preset condition may be an error rate of the AEBS simulated brake when the vehicle travels a certain distance on average. For example, if the preset condition requires an erroneous simulated brake to occur at an average distance of 1000 km, the AEBS in the simulated state will issue at most one wrong braking command during the average 1000 km travel. According to this example, the vehicle participating in the verification travels at least 1000km, and during the simulated braking within 1000km, the brake command is issued without error, and the preset condition can be satisfied.

[0041] Different vehicle types may have different requirements for the AEBS system. Therefore, the parameter group in the AEBS system verification process varies from customer to customer, but the parameter group determined for the prior customer is for the latter. The customer has certain reference value. For example, after the customer can set the parameter group based on the parameter group of the previous customer, the verification result is obtained according to the verification process as described above, and the adjustment is made again if the result is not satisfactory. Verify until you get a parameter set that meets the preset criteria. This approach is especially advantageous where customer requirements are similar.

[0042] In summary, in the example of the present invention, the verification of the AEBS is performed during the driving verification process after the vehicle is assembled, or by the terminal customer vehicle, thereby being independent of the project implementation phase of completing the vehicle. Therefore, the project time for the entire vehicle is shortened. At the same time, with this method, multiple parameter groups can be set with reference to the AEBS system of the preceding vehicle, so that the verification process is more targeted. In addition, collecting data from these three parameter sets simultaneously shortens the acquisition time of the verification data. In general, the verification method and/or verification system according to the present invention will be more effective for verification of AEBS.

[0043] According to an example of the present invention, there is also provided a system for collecting data used by an automatic emergency braking system verification process, comprising a storage module and a collection module. The storage module is disposed in an automatic emergency braking system of each vehicle to store a parameter group loaded into an automatic emergency braking system of each vehicle, wherein a parameter group of the automatic emergency braking system loaded with each vehicle is The parameter sets described herein are consistent, including at least one of a parameter set for conservative braking, a parameter set for moderate braking, and a parameter set for early braking, wherein each vehicle loads a parameter set. The collection module collects data relating to the simulated braking of the automatic emergency braking system during the travel of each vehicle. The storage module can be, for example A storage module of the AEBS system, for example, disposed in a sensor of the automatic emergency braking system for sensing an obstacle in front of the vehicle, such as a radar sensor. As an example, the collection module can communicate the collected brake data to a monitoring device of the automatic emergency braking system, and the storage module is configured to store updated data from the monitoring device of the automatic emergency braking system. The monitoring device is provided, for example, in the central control room as described above, and the update data is, for example, an updated parameter group or the like.

The AEBS system with both the system and the method shown in Figure 2 was validated. The thus-proven AEBS system in which the parameters set for the AEBS system are set are the parameter sets described above that satisfy the preset conditions for the AEBS.
