Description

Technical Field

[0001] This application relates to the field of computer technology, and in particular to a method, apparatus, computer device, storage medium, and computer program product for generating relational data. Background Technology

[0002] Currently, the industry generally addresses the drivability requirements of gasoline, hybrid, and pure electric vehicles by pre-calibrating drivability charts. However, this method often results in a period of inactivity at high speeds and low throttle. This is because at higher speeds, even with low throttle, the torque is relatively low, leading to a situation where the vehicle continues to decelerate despite acceleration. Drivers often feel that pressing the accelerator will at least prevent the vehicle from slowing down, which would be more comfortable. This is where the one-pedal driving concept comes in. With light throttle input, the vehicle can recover energy, effectively slowing it down.

[0003] For the one-pedal mode, the pedal opening is pre-calibrated using a drivability chart to ensure the vehicle does not decelerate. This method involves a large amount of calibration data, and if the drivability chart is updated, recalibration is required, which increases the calibration workload. Summary of the Invention

[0004] Therefore, it is necessary to provide a relational data generation method, apparatus, computer equipment, computer-readable storage medium, and computer program product that can save calibration workload in response to the above-mentioned technical problems.

[0005] Firstly, this application provides a method for generating relational data, the method comprising:

[0013] The step of generating second relational data to characterize the relationship between the accelerator pedal opening and the adjustment demand information includes: generating second relational data to characterize the relationship between the adjustment demand information corresponding to each speed, the speed in the first relational data, and the accelerator pedal opening.

[0014] In one embodiment, the step of generating adjustment requirement information for the pedal opening corresponding to each accelerator pedal opening based on the target accelerator pedal opening and each accelerator pedal opening in the first relationship data includes:

[0015] For each accelerator pedal opening in the first relational data, determine the difference between the target accelerator pedal opening and the current accelerator pedal opening;

[0016] Based on the difference and the target accelerator pedal opening, the percentage of the current accelerator pedal opening that is not completed is determined, and the percentage of the incomplete opening is used as the adjustment requirement information.

[0017] In one embodiment, determining the percentage of incomplete pedal opening based on the difference and the target accelerator pedal opening includes:

[0018] If the difference is less than or equal to a preset difference threshold, the ratio between the difference and the target accelerator pedal opening is taken as the percentage of non-completion.

[0019] If the difference is greater than the preset difference threshold, then the percentage of incomplete work is set to the preset percentage.

[0020] In one embodiment, before determining the target accelerator pedal opening corresponding to the torque threshold based on the first relationship data, the method further includes:

[0021] Verify whether there is a positive correlation between accelerator pedal opening and torque;

[0022] If so, then generate a message indicating successful verification of the first relationship data;

[0023] The step of determining the target accelerator pedal opening corresponding to the torque critical value based on the first relationship data includes:

[0024] When the verification success message is detected, the target accelerator pedal opening corresponding to the torque threshold is determined based on the first relationship data.

[0025] In one embodiment, after generating second relational data characterizing the relationship between the accelerator pedal opening and the adjustment demand information, the method further includes:

[0026] Based on the second relationship data, the adjustment requirement information corresponding to the current accelerator pedal opening of the vehicle is displayed;

[0027] When the system detects that the user has adjusted the current accelerator pedal opening, it determines the adjustment requirement information corresponding to the adjusted accelerator pedal opening based on the second relationship data, and updates the displayed adjustment requirement information based on the adjustment requirement information corresponding to the adjusted accelerator pedal opening.

[0028] Secondly, this application also provides a relational data generation apparatus, comprising:

[0029] The acquisition module is used to acquire first relationship data, which is used to characterize the relationship between the accelerator pedal opening and torque of the vehicle.

[0030] The determination module is used to determine the target accelerator pedal opening corresponding to the torque critical value based on the first relationship data, wherein the torque critical value is the torque corresponding to maintaining the vehicle speed at the current vehicle speed;

[0031] The first generation module is used to generate adjustment requirement information for the pedal opening corresponding to each accelerator pedal opening based on the target accelerator pedal opening and each accelerator pedal opening in the first relationship data.

[0036] The aforementioned relational data generation method, apparatus, computer equipment, storage medium, and computer program product acquire first relational data, which characterizes the relationship between the accelerator pedal opening and torque of a vehicle. Based on this first relational data, a target accelerator pedal opening corresponding to a torque threshold value is determined. This torque threshold value is the torque required to maintain the vehicle's current speed. Therefore, as long as the vehicle maintains this target accelerator pedal opening, the vehicle can maintain its current speed. Based on the target accelerator pedal opening and the accelerator pedal openings in the first relational data, adjustment requirement information for the pedal opening corresponding to each accelerator pedal opening is generated. Then, after generating second relational data characterizing the relationship between the accelerator pedal opening and the adjustment requirement information, it can be used to... The second relational data directly determines the adjustment requirements for the accelerator pedal opening. Adjusting the accelerator pedal according to these requirements allows the vehicle to maintain its current speed. Therefore, this application only needs to obtain the first relational data to automatically generate the second relational data using the aforementioned method. Adjusting the accelerator pedal according to the adjustment requirements in the second relational data allows the vehicle to maintain its current speed without needing to pre-calibrate the pedal opening based on the first relational data to prevent the vehicle from decelerating. This reduces calibration workload. Furthermore, the second relational data can be automatically generated based on the first relational data using the aforementioned method, and even if the first relational data is updated, the second relational data can be updated accordingly without recalibration.

[0043] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0044] In one embodiment, such as Figure 1 As shown, a method for generating relational data is provided. This embodiment applies this method to vehicles. In this embodiment, the method includes the following steps:

[0045] Step S101: Obtain first relational data, which is used to characterize the relationship between the accelerator pedal opening and torque of the vehicle;

[0046] For one-pedal vehicles, there is a correlation between the vehicle's torque and the accelerator pedal. This first correlation data is used to characterize the relationship between the accelerator pedal opening and the torque.

[0047] In this embodiment, different vehicle speed conditions correspond to different first relationship data; that is, under each vehicle speed condition, there is a corresponding relationship between the accelerator pedal opening and the torque. In order to keep the current vehicle speed constant, it is necessary to obtain the first relationship data under the current vehicle speed condition.

[0048] Step S102: Based on the first relationship data, determine the target accelerator pedal opening corresponding to the torque critical value. The torque critical value is the torque required to maintain the vehicle speed at the current speed.

[0049] As the accelerator pedal opening changes, the torque also changes accordingly. It is necessary to determine the target accelerator pedal opening corresponding to the torque critical value.

[0050] In this embodiment, the torque threshold value is the torque required to maintain the vehicle speed at the current speed. Therefore, as long as the vehicle pedal opening remains at the target accelerator pedal opening corresponding to the torque threshold value, the vehicle can maintain the current speed.

[0051] Step S103: Based on the target accelerator pedal opening and each accelerator pedal opening in the first relationship data, generate adjustment requirement information for the pedal opening corresponding to each accelerator pedal opening.

[0052] The vehicle determines the difference between each accelerator pedal opening in the first relational data and the target accelerator pedal opening, and determines the adjustment requirement information of each accelerator pedal opening based on the difference.

[0053] Step S104: Generate second relational data to characterize the relationship between accelerator pedal opening and adjustment demand information.

[0054] Based on the opening degree of each accelerator pedal and the corresponding adjustment requirement information, a second relational data is generated to characterize the relationship between the opening degree of each accelerator pedal and the adjustment requirement information.

[0055] Based on the demand adjustment information in the second relational data, the vehicle adjusts the accelerator pedal opening to reach the target accelerator pedal opening, thereby enabling the vehicle to maintain its current speed.

[0056] In this embodiment, both the first relation data and the second relation data can be chart data.

[0057] In this embodiment, first relational data is obtained, which characterizes the relationship between the accelerator pedal opening and torque of the vehicle. Based on this first relational data, a target accelerator pedal opening corresponding to a torque threshold value is determined. This torque threshold value is the torque required to maintain the vehicle's current speed. Therefore, as long as the vehicle maintains this target accelerator pedal opening, the vehicle can maintain its current speed. Based on the target accelerator pedal opening and the accelerator pedal openings in the first relational data, adjustment requirement information for each accelerator pedal opening is generated. Then, second relational data is generated to characterize the relationship between the accelerator pedal opening and the adjustment requirement information. Based on the second relational data, the accelerator pedal opening can be directly determined. The application addresses the need to adjust the accelerator pedal opening. By adjusting the accelerator pedal according to this adjustment requirement, the vehicle speed can be maintained at the current speed. Therefore, this application only needs to obtain the first relational data, and the machine can automatically generate the second relational data in the manner described above. Adjusting the accelerator pedal according to the adjustment requirement information in the second relational data will maintain the vehicle speed at the current speed, eliminating the need for pre-calibration based on the first relational data to ensure the pedal opening does not decelerate. This reduces calibration workload. Furthermore, the second relational data can be automatically generated based on the first relational data in the manner described above, and even if the first relational data is updated, the second relational data can be updated accordingly without recalibration.

[0058] In one embodiment of this application, the first relationship data is two-dimensional data, such as the relationship between the accelerator pedal opening and torque under the current speed condition, as described above.

[0059] Another possibility is that the first relational data is used to characterize the relationship between vehicle speed, accelerator pedal opening, and torque;

[0060] The first relational data is three-dimensional data, used to characterize the relationship between the three dimensions of vehicle speed, accelerator pedal opening and torque. In this way, the first relational data can directly characterize the relationship between accelerator pedal opening and torque under different speed conditions.

[0061] The step of determining the target accelerator pedal opening corresponding to the torque critical value based on the first relationship data includes: for each speed, determining the target accelerator pedal opening corresponding to the torque critical value under the current speed condition based on the first relationship data;

[0062] In this embodiment, for each speed in the first relational data, it is necessary to determine the target accelerator pedal opening corresponding to the torque critical value when the speed is constant. In this way, the corresponding target accelerator pedal opening can be determined for each speed.

[0063] For example, the first relational data includes speeds V1, V2, and V3. When the vehicle speed is V1, the target accelerator pedal opening corresponding to the torque threshold N1 is X1. When the vehicle speed is V2, the target accelerator pedal opening corresponding to the torque threshold N2 is X2. When the vehicle speed is V3, the target accelerator pedal opening corresponding to the torque threshold N3 is X3.

[0064] In this embodiment, as long as the accelerator pedal opening reaches the target accelerator pedal opening, the vehicle can maintain the speed corresponding to the target accelerator pedal opening.

[0065] The step of generating adjustment requirement information for pedal opening corresponding to each accelerator pedal opening based on the target accelerator pedal opening and each accelerator pedal opening in the first relationship data includes: for each speed, generating adjustment requirement information for pedal opening corresponding to each accelerator pedal opening based on the target accelerator pedal opening under the current speed condition and each accelerator pedal opening in the first relationship data.

[0066] In this embodiment, for each vehicle speed in the first relational data, if the target accelerator pedal opening corresponding to the current vehicle speed has been determined as above, the difference between each accelerator pedal opening in the first relational data and the target accelerator pedal opening is calculated to obtain the adjustment requirement corresponding to each accelerator pedal opening. The adjustment requirement of each accelerator pedal opening constitutes the adjustment requirement information corresponding to the speed condition.

[0067] As can be seen, this application can ultimately obtain the adjustment requirement information corresponding to each data in the first relational data;

[0068] For example, when the vehicle speed is speed V1, the target accelerator pedal opening corresponding to the torque threshold N1 is X1. Then, the differences between the multiple accelerator pedal openings X0, X1, X2 and X3 in the first relational data and X1 are calculated respectively, so as to obtain the adjustment requirements corresponding to X0, X1, X2 and X3 respectively. For vehicle speeds V2 and V3, the adjustment requirement information corresponding to speeds V2 and V3 is obtained in the same way.

[0069] The step of generating second relational data to characterize the relationship between the accelerator pedal opening and the adjustment demand information includes: generating second relational data to characterize the relationship between the adjustment demand information corresponding to each speed, the speed in the first relational data, and the accelerator pedal opening.

[0070] The vehicle generates second relational data, which is also three-dimensional data. The three dimensions are the speed in the first relational data, the accelerator pedal opening in the first relational data, and the adjustment requirements corresponding to the speed. Based on the second relational data, the adjustment requirements of different accelerator pedal openings can be determined to keep the current speed constant under various speed conditions.

[0071] As can be seen, a vehicle only needs to know its current speed and current accelerator pedal opening to look up the second relational data to determine the corresponding adjustment requirements. This allows the accelerator pedal opening to be adjusted so that the vehicle's current speed remains unchanged. The second relational data can be directly generated from the first relational data, and the adjustment requirements for the accelerator pedal can be determined based on the second relational data. There is no need to calibrate the first relational data to determine how to adjust the accelerator pedal to keep the current speed unchanged, thus saving calibration workload.

[0072] Furthermore, the second relational data generated in this application characterizes the adjustment requirements of the accelerator pedal under different speed conditions. The second relational data expresses richer content and has stronger applicability.

[0073] In one embodiment, generating adjustment requirement information for the pedal opening corresponding to each accelerator pedal opening based on the target accelerator pedal opening and each accelerator pedal opening in the first relational data includes: determining the difference between the target accelerator pedal opening and the current accelerator pedal opening for each accelerator pedal opening in the first relational data; determining the uncompleted percentage of the current accelerator pedal opening based on the difference and the target accelerator pedal opening; and using the uncompleted percentage as the adjustment requirement information.

[0074] The first relational data includes multiple accelerator pedal openings. For each accelerator pedal opening, the difference between the current accelerator pedal opening and the target accelerator pedal opening is calculated to obtain the difference corresponding to the current accelerator pedal opening. Then, the percentage between the difference corresponding to the current accelerator pedal opening and the target accelerator pedal opening is determined to obtain the uncompleted percentage of the current accelerator pedal opening. This uncompleted percentage is the adjustment requirement information corresponding to the current accelerator pedal opening. In this way, the adjustment requirement information corresponding to each accelerator pedal opening can be calculated.

[0075] In one embodiment, determining the percentage of incomplete pedal opening based on the difference and the target accelerator pedal opening includes: if the difference is less than or equal to a preset difference threshold, then the ratio between the difference and the target accelerator pedal opening is taken as the percentage of incomplete opening; if the difference is greater than the preset difference threshold, then the percentage of incomplete opening is set as a preset percentage.

[0076] If the difference is greater than 0, it means that the current accelerator pedal opening is greater than the target accelerator pedal opening. This means that the current accelerator pedal opening has been adjusted to the target accelerator pedal opening, and the vehicle can maintain the current speed. In this case, the percentage of incomplete progress is set to 0.

[0077] If the difference is less than or equal to the preset difference threshold, the ratio between the difference and the target accelerator pedal opening is calculated, and the ratio is converted into a percentage, which is the uncompleted percentage of the current accelerator pedal opening.

[0078] For example, Xv represents the target accelerator pedal opening corresponding to the torque threshold, P represents the current accelerator pedal opening, and Zpct represents the adjustment requirement information.

[0079] When P > Xv, Zpct = 0; when 0 <P<Xv,Zpct=(Xv-P) / Xv*100%;

[0080] In the embodiments of this application, the method for determining the adjustment requirement information for each speed is the same. The percentage of the accelerator pedal opening that is not completed under each speed condition can be determined in the manner described above, thereby obtaining the adjustment requirement information under each speed condition.

[0081] In one embodiment, before determining the target accelerator pedal opening corresponding to the torque threshold based on the first relationship data, the method further includes: verifying whether the accelerator pedal opening and torque are positively correlated; if so, generating a verification success message for the first relationship data; determining the target accelerator pedal opening corresponding to the torque threshold based on the first relationship data includes: when the verification success message is detected, determining the target accelerator pedal opening corresponding to the torque threshold based on the first relationship data.

[0082] In this embodiment, it is necessary to verify whether the torque value corresponding to the accelerator pedal opening from small to large is a process of small to large, that is, whether the next torque value is greater than or equal to the previous torque value. The validity of the first relationship data is verified in this way. If the verification is successful, the target accelerator pedal opening corresponding to the torque critical value can be determined by the first relationship data. If the verification fails, it will indicate that the first relationship data calibration is unreasonable and the coasting limit cannot be found.

[0083] In one embodiment, after generating second relationship data to characterize the relationship between the accelerator pedal opening and the adjustment demand information, the method further includes: displaying adjustment demand information corresponding to the current accelerator pedal opening of the vehicle based on the second relationship data; when it is detected that the user adjusts the current accelerator pedal opening, determining the adjustment demand information corresponding to the adjusted accelerator pedal opening based on the second relationship data, and updating the displayed adjustment demand information based on the adjustment demand information corresponding to the adjusted accelerator pedal opening.

[0084] Based on the second relationship data, the vehicle can display the adjustment requirements corresponding to the current accelerator pedal opening to the user. The user can then adjust the accelerator pedal opening based on this adjustment requirement information. It is understandable that the current accelerator pedal opening will change accordingly during the adjustment process, and the adjustment requirement information will also change accordingly. Therefore, the adjustment requirements displayed on the vehicle's display interface need to be updated in real time so that the user can better understand the adjustment requirements for maintaining the current vehicle speed and accelerator pedal.

[0085] For example, if the current accelerator pedal opening is X1, the vehicle displays that the accelerator pedal is 50% uncompleted. If the user increases the accelerator pedal opening to X2, the vehicle displays that the accelerator pedal is 30% uncompleted. If the user continues to increase the accelerator pedal opening to X3, the vehicle displays that the accelerator pedal is 0% uncompleted, indicating that by maintaining the accelerator pedal opening at X3, the vehicle can maintain its current speed and there is no need to continue increasing the accelerator pedal opening.

[0086] In this embodiment, the first relationship data is drivability chart data, and the second relationship data is single-pedal characteristic chart data. The overall solution of this application is described below:

[0087] S1, such as Figure 1 As shown, drivability charts typically use vehicle speed as the X-axis, accelerator pedal opening as the Y-axis, and torque as the Z-axis.

[0088] Using vehicle speed as the standard, determine the torque value corresponding to the process of the accelerator pedal opening changing from 0% to 100% under each vehicle speed condition. At the same time, determine whether the change of torque value is also from small to large. Validate the validity of the driving performance chart data in this way. If the validation is successful, proceed to S2. If it is unsuccessful, indicate that the driving performance chart data calibration is unreasonable and the coasting limit cannot be found.

[0089] S2. Finding the coasting limit: The approach is as follows: For each vehicle speed on the drivability chart, determine the torque value corresponding to the change of accelerator pedal opening from 0% to 100% at the current vehicle speed. Then, compare the torque values ​​corresponding to the accelerator pedal opening from 0% to 100% to find the torque threshold (the next torque value of the torque threshold is greater than 0, and the previous torque value is less than 0). Record the accelerator pedal opening corresponding to the torque threshold as the coasting limit. In this way, find the coasting limit under various vehicle speed conditions.

[0090] S3. For vehicles, acceleration, coasting, and deceleration need to transition smoothly to ensure vehicle smoothness. Therefore, the original coasting boundary line is extended to create a coasting zone, such as... Figure 2 ( Figure 2 The graph (where the horizontal axis represents vehicle speed and the vertical axis represents torque) shows the coasting boundary diagram. Then, the boundary L is used as the single-pedal activation boundary, forming a two-dimensional curve with vehicle speed as the input, as shown below. Figure 3 ( Figure 3 The graph shown is a single-pedal curve (with vehicle speed on the horizontal axis and torque on the vertical axis).

[0091] In the generated single-pedal chart, the vehicle speed is the x-axis of the single-pedal chart, the accelerator pedal opening is the Y-axis of the single-pedal image, and the Z-axis represents the adjustment requirements for the pedal opening.

[0092] This application can quickly extract the vehicle's coasting limits based on the drivability chart, and then automatically generate a single-pedal chart through chart reconstruction, effectively reducing calibration time and workload.

[0093] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders.
