[0025] The detailed description of the accompanying drawings is intended as an illustration of the currently preferred embodiment of the present application, and is not intended to represent the only form in which the present application can be implemented. It should be understood that the same or equivalent functions can be accomplished by different embodiments intended to be included in the spirit and scope of the present application.

[0026] An embodiment of the present application provides an ADAS system debugging method. The method of this embodiment performs an open-loop CAPL (Communication Access Programming Language) test on real vehicles of different models. The open-loop CAPL test refers to a CAPL script test performed using a test tool such as CANoe or CANalyzer under the actual operation state of the vehicle. The test condition is that the IFC (Intelligent Front Camera) requests a left and right slope force with a torque slope of 5Nm / s and a maximum value of 2Nm, and the Canoe tool is used to record the test data during the test. The CAN data of the EPS system responses of different models are analyzed based on the collected data to obtain data such as the dead zone and response time of the EPS system under the same road section and the same speed. Furthermore, based on the lateral performance of the ICA function (Intelligent Cruise Assist) of the ADAS system obtained by analyzing the objective data analysis tool Matlab software, a comprehensive comparative analysis is performed in combination with the software architecture and hardware system selection of the EPS. For example, as shown in Table 1 below, the key factors of the EPS system affecting the lateral performance of the ADAS system are obtained, and the key factors mainly include the dead zone and response time of the EPS system.

[0027] Table 1- Performance parameters of different types of EPS

[0028]

[0029]

[0030] See also Figure 1 As shown, the method of this embodiment includes the following steps:

[0031] Step S10, obtaining the measured dead zone value of the EPS system at different vehicle speeds, and the measured response time of the EPS system at different vehicle speeds and torque requests.

[0032] Specifically, the dead zone of the EPS system refers to the initial force required to turn the steering wheel near the center of the steering angle without the vehicle making any obvious turns. A smaller dead zone can improve the steering system's sensitivity and accuracy to the driver's commands. However, too small a dead zone may cause the steering wheel to malfunction or vibrate during normal driving. Therefore, the size of the dead zone needs to be appropriately adjusted while ensuring sensitivity and accuracy. The response time of the EPS system refers to the time from the issuance of a torque request to the actual start of the vehicle's steering. Responding to commands quickly and accurately is very important for safety and handling performance. A smaller response time can improve vehicle handling performance, but factors such as system stability, comfort, and whether other system components (such as hydraulic pumps) can meet the requirements must also be considered.

[0033] Furthermore, actual vehicle tests can be conducted to obtain the measured dead zone values ​​of the EPS system under different vehicle speed states, as well as the measured response time of the EPS system under different vehicle speeds and torque requests. The measured response time of the EPS system under different vehicle speeds and torque requests refers to the measured response time of the EPS system obtained by inputting different torque requests at each vehicle speed.

[0034] Step S20, determining the gain coefficient of the EPS system of the vehicle under different speeds and different torque requests based on the measured dead zone value, the measured response time and constraints; wherein the constraints include making the dead zone of the EPS system fall within a preset dead zone recommended value range, and making the response time of the EPS system fall within a recommended response time value range.

[0035] Specifically, if the dead zone is too large, the response and following will be poor; if the dead zone is too small, the response and following will be too sensitive. In disturbed scenarios, the steering wheel will move more. Therefore, it is necessary to ensure that the dead zone of the EPS system falls within the preset dead zone recommended value range; if the response time is too slow, the response and following will be poor; if the response time is too fast, the response and following will be too sensitive. In disturbed scenarios, the steering wheel will move more. Therefore, it is necessary to ensure that the response time of the EPS system falls within the recommended response time value range.

[0036] Further, after obtaining the gain coefficient of the EPS system of the vehicle at different speeds and different torque requests, the following equation can be generated: Figure 2 The gain coefficient table shown stores the gain coefficient data in a table.

[0037] For example, if the gain coefficient is greater than 1, the torque request will be amplified, and the EPS system will respond to the input signal relatively quickly and in a short time; if the gain coefficient is less than 1, the torque request will be reduced, and the EPS system will respond to the input signal relatively slowly and in a long time; by adjusting the gain coefficient, the EPS system's response to the driver's input at different vehicle speeds can be optimized, thereby improving handling and driving comfort; therefore, using the calculated gain coefficient is a very important step in the EPS system debugging and optimization process.

[0038] Step S30, debugging the performance parameters of the smart cruise assist function of the ADAS system according to the gain coefficient of the EPS system at different speeds and different torque requests of the vehicle.

[0039] Specifically, the gain coefficient table calculated in step S20 is input as a parameter to freeze the interface parameters between the EPS software and the ADAS system. That is, the gain coefficient table of the EPS system will no longer be adjusted or modified during the development and debugging of the ADAS system. In this way, the ADAS system will be controlled according to the gain coefficient table to achieve the required steering torque request.

[0040] Among them, Intelligent Cruise Assist (ICA) is an important function of the ADAS system. It uses radar, cameras and other sensors to monitor the distance and speed of the vehicle in front, and automatically adjusts the speed of the vehicle to maintain a safe distance from the vehicle in front. ICA can automatically accelerate or decelerate according to traffic conditions, and can even stop completely when necessary. Based on the frozen gain coefficient table, the performance parameters related to the ICA function of the ADAS system are debugged, which involves adjusting the algorithms, parameters and thresholds related to the ICA function to ensure that the ADAS system can accurately and stably control steering according to the torque request of the IFC smart camera.

[0041] Further, Figure 3 The ADAS system lateral torque request transmission path is shown. Figure 3As shown, under the condition that the LKA (LaneKeeping Assist) function is activated, the LKA function uses the slope limit (the slope limit is determined according to the vehicle speed) and the LKA limit (absolute value limit) to calculate the torque request value of the LKA function. On the one hand, the torque value after LKA gain is obtained according to the torque request value of the LKA function and the gain coefficient table calculated in step S20. The torque value after gain is superimposed on the driver's hand force value to obtain a part of the required motor-end torque through the basic power-assist module of EPS. On the other hand, according to the torque request value of the LKA function, the LKA table lookup value under different vehicle speed conditions is queried to obtain a part of the required motor-end additional torque. Finally, the sum of the motor-end torque and the motor-end additional torque is the request for the EPS motor-end execution torque; wherein, the relationship between the motor-end torque additional value and the torque request value of the LAK function under different speed conditions is as follows: Figure 4 As shown, according to Figure 4 The LKA table value can be obtained. Figure 3 and Figure 4 Based on the content of the control table, the ADAS system will perform control according to the gain coefficient table to achieve the required steering torque request.

[0042] Based on the description of the above embodiments, it can be known that the method of this embodiment is based on the results of the preliminary analysis of the key influencing factors of the EPS system on the lateral performance of the ADAS system, and determines that the dead zone and response time of the EPS system are important factors affecting the lateral performance of the ADAS system. Therefore, it is proposed to determine the gain coefficient of the EPS system of the vehicle at different speeds and different torque requests according to the "measured dead zone value of the EPS system at different vehicle speeds" and the "measured response time of the EPS system at different vehicle speeds and torque requests", and make the dead zone of the EPS system fall within the preset dead zone recommended value range, and the response time of the EPS system fall within the response time recommended value range; then, freeze the interface parameters of the EPS software and the ADAS system, that is, the gain coefficient of the EPS system of the vehicle at different speeds and different torque requests, and debug the performance parameters of the intelligent cruise assist function of the ADAS system, which can improve the efficiency of the ADAS system in the development process.

[0043] Further, REPS (Rack Electric Power Steering) and CEPS (Column Electric Power Steering) are two different electric power steering systems used for steering control of automobiles;

[0044] The REPS system refers to an electric power steering device installed on a traditional rack mechanism. It uses a motor and sensors to provide additional assistance, making it easier for the driver to operate the steering wheel. The REPS system is usually installed at the front of the vehicle, close to the engine compartment;

[0045] The CEPS system integrates the electric power steering device into the steering column. This design makes the CEPS system more compact and lightweight, and can more directly sense the driver's control intentions. Due to its high degree of integration, the CEPS system is usually installed near the driver's seat of the vehicle.

[0046] On the basis of giving priority to ensuring the lateral performance of the ADAS system, the EPS system of this embodiment adopts a REPS system.

[0047] In some embodiments, the measured dead zone values ​​of the EPS system at different vehicle speeds are specifically:

[0048] The torque request output by the vehicle's intelligent front camera when the vehicle's steering wheel starts to turn from zero position at different vehicle speeds.

[0049] Specifically, the vehicle intelligent front camera refers to an intelligent front camera (IFC) installed at the front of the vehicle, which uses a high-resolution camera and image processing algorithm to monitor and analyze the road environment ahead in real time and provide information related to driving assistance functions. In the ADAS system of this embodiment, the torque request refers to the command signal sent by the IFC to the EPS system, which is used to inform the EPS system how much steering torque needs to be applied to achieve a specific driving assistance function.

[0050] Specifically, the IFC smart camera can identify and track objects by monitoring lane lines, traffic signs, pedestrians, etc. on the road ahead. Based on this information, it can calculate situations where steering input is required, such as keeping the vehicle in the lane, performing lane departure warnings, or performing automatic slalom operations. The IFC smart camera then sends the corresponding torque request signal to the EPS system to achieve the required steering control.

[0051] In some embodiments, the measured response time of the EPS system under different vehicle speeds and torque requests is specifically:

[0052] The time from when the vehicle’s intelligent front camera outputs a torque request to when the vehicle’s steering wheel starts to turn at different vehicle speeds.

[0053] Specifically, during the vehicle measurement process, under different vehicle speed conditions, the vehicle's intelligent front camera is controlled to output different torque requests to the EPS system, and the time when the vehicle's steering wheel starts to turn is monitored, so as to obtain the EPS measured response time under different vehicle speeds and torque request conditions.

[0054] In some embodiments, the step S30 specifically includes:

[0055] Step S301, dividing the measured dead zone values ​​of the EPS system at different vehicle speeds by the dead zone recommended value range respectively to obtain the gain coefficient range of the EPS system at different vehicle speeds;

[0056] Step S302, based on the measured response time of the EPS system under different vehicle speeds and torque requests, and the gain coefficient range of the EPS system under different vehicle speeds, determine the gain coefficient of the EPS system under different vehicle speeds and different torque requests, so that under different vehicle speeds and torque requests, the response time of the EPS system falls within the recommended response time value range.

[0057] Specifically, the gain coefficient range obtained in step S301 can satisfy that the dead zone of the vehicle EPS system falls within the preset dead zone recommended value range. Therefore, step S302 can further select a suitable gain coefficient based on this gain coefficient range, as long as the selected gain coefficient also satisfies that the response time of the EPS system falls within the recommended response time value range under different vehicle speeds and torque requests; specifically, the larger the gain coefficient, the shorter the corresponding response time, and the smaller the gain coefficient, the longer the corresponding response time. Based on this principle, a suitable gain coefficient can be further selected within the gain coefficient range obtained in step S301.

[0058] In some embodiments, the recommended dead zone value range is 0.8Nm to 1.0Nm, and the recommended response time value range is 150ms to 250ms.

[0059] Specifically, in this embodiment, the recommended value range of the dead zone is 0.8Nm~1.0Nm, which can effectively avoid the situation where the dead zone is too large and the response and following are poor, and the dead zone is too small and the response and following are too sensitive, and the steering wheel movements will increase in disturbed scenarios; the recommended value range of the response time is 150ms~250ms, which can effectively avoid the situation where the response time is too slow and the response and following are poor, and the response time is too fast and the response and following are too sensitive, and the steering wheel movements will increase in disturbed scenarios.

[0060] Corresponding to the method of the above embodiment, another embodiment of the present application provides an ADAS system debugging device, see Figure 5 , the device comprises:

[0063] The debugging module is used to debug the performance parameters of the intelligent cruise assist function of the ADAS system according to the gain coefficient of the EPS system under different speeds and different torque requests of the vehicle.
