Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0024] The following describes an ACC data-driven optimization method, apparatus, vehicle, and storage medium according to embodiments of the present application with reference to the accompanying drawings. Addressing the problems mentioned in the background art regarding the cumbersome data acquisition for ACC acceleration calibration and optimization, and the inability to cover all scenarios, the present application provides an ACC data-driven optimization method. In this method, at least one data source is acquired and input into a preset ACC functional model to obtain acceleration function evaluation indicators. The gain values ​​of the acceleration indicator, acceleration time indicator, and steady-state time indicator are calculated respectively to obtain the acceleration indicator gain, acceleration time indicator gain, and steady-state time indicator gain. Based on these gains, a comprehensive acceleration gain is obtained, and acceleration optimization is performed based on this comprehensive gain. This solves the problem of cumbersome data acquisition for ACC acceleration calibration and optimization, and the inability to cover all scenarios in the related art. By adopting a data-driven approach for optimization and parameter tuning, it covers a vast majority of operating conditions. Data is automatically associated and parameters are automatically tuned based on evaluation indicators, eliminating the need for extensive testing to acquire data and significantly saving optimization time.

[0025] Specifically, Figure 1 This is a flowchart illustrating an ACC data-driven optimization method provided in an embodiment of this application.

[0026] like Figure 1 As shown, the ACC data-driven optimization method includes the following steps: In step S101, at least one data source is obtained.

[0027] Specifically, the data source obtained in the embodiments of this application can be as follows: Figure 2As shown, it includes two parts: initial vehicle speed and expected vehicle speed, covering all acceleration ranges during ACC. It can be based on different data sources, covering all working conditions and scenarios, and the data-driven optimization model can be tuned.

[0028] In step S102, at least one data source is input into the preset ACC function model to obtain acceleration function evaluation indicators, wherein the acceleration function evaluation indicators include acceleration indicators, acceleration time indicators and steady-state time indicators.

[0029] Specifically, in this embodiment of the application, after obtaining at least one data source, the at least one data source is input into a preset ACC function model to obtain acceleration index, acceleration time index and steady-state time index.

[0030] As one possible approach, different data sources are used as variables input to the ACC functional model. The ACC optimizes the acceleration and evaluates the collected data, including: actual acceleration during the process, maximum acceleration, acceleration time (time taken to accelerate to the desired vehicle speed), and steady-state time (time taken to go from maximum speed to steady-state speed).

[0031] In step S103, the gain values ​​of acceleration index, acceleration time index and steady-state time index are calculated respectively to obtain the acceleration index gain, acceleration time index gain and steady-state time index gain. The comprehensive acceleration gain is obtained based on the acceleration index gain, acceleration time index gain and steady-state time index gain, and acceleration optimization is performed based on the comprehensive acceleration gain.

[0032] Specifically, such as Figure 3 As shown, Figure 3 This is a flowchart for calculating the ACC evaluation index according to one embodiment of this application.

[0033] Step S301: Collect data, including: actual acceleration during the process, maximum acceleration, acceleration time (time taken to accelerate to the desired vehicle speed), and steady-state time (time taken to go from maximum speed to steady-state speed).

[0034] Step S302 involves calculating the gain values ​​of the acceleration index, acceleration time index, and steady-state time index, respectively, to obtain the acceleration index gain, acceleration time index gain, and steady-state time index gain. This includes: calculating the index gain of the acceleration index based on a preset acceleration index gain strategy, wherein the preset acceleration index gain strategy is as follows: Acceleration index gain = (1 + (a_realmax - a_max) / a_realmax); Where a_realmax is the actual maximum acceleration and a_max is the maximum constrained acceleration.

[0035] Specifically, obtain the maximum constrained acceleration a_max and the actual maximum acceleration a_realmax within the velocity range of at least one data source x, and calculate the acceleration index gain (1+(a_realmax-a_max) / a_realmax).

[0036] Step S303 involves calculating the gain values ​​of the acceleration index, acceleration time index, and steady-state time index, respectively, to obtain the acceleration index gain, acceleration time index gain, and steady-state time index gain. It also includes: calculating the acceleration time index gain based on a preset acceleration time index gain strategy, wherein the preset acceleration time index gain strategy is as follows: Acceleration time index gain = (1 + (Tm - T(m-1)) / T(m-1)); Where Tm is the acceleration time of the mth acceleration, and T(m-1) is the acceleration time of the (m-1)th acceleration.

[0037] Specifically, the acceleration time of the mth time is set as Tm, and the acceleration time of the (m-1)th time is set as T(m-1). The acceleration time index gain is calculated as (1+(Tm-T(m-1)) / T(m-1)).

[0038] Step S304 involves calculating the gain values ​​of the acceleration index, acceleration time index, and steady-state time index, respectively, to obtain the gain of the acceleration index, acceleration time index, and steady-state time index. This includes: calculating the gain of the steady-state time index based on a preset steady-state time index gain strategy, wherein the preset steady-state time index gain strategy is as follows: Steady-state time index gain = (1 + (tm - t(m-1)) / t(m-1)); Where tm is the m-th steady-state time, and t(m-1) is the (m-1)-th steady-state time.

[0039] Step S305: Obtain the comprehensive acceleration gain based on the acceleration index gain, acceleration time index gain, and steady-state time index gain, including: Comprehensive acceleration gain = Acceleration index gain * Acceleration time index gain * Steady-state time index gain.

[0040] Specifically, let the steady-state time of the data source x be tm and the steady-state time of the (m-1)th iteration be t(m-1). Calculate the steady-state time index gain as (1+(tm-t(m-1)) / t(m-1)).

[0041] Optionally, in some embodiments, after performing acceleration optimization based on the acceleration composite gain, the method further includes: obtaining the previous acceleration optimization result and the current acceleration optimization result; if the previous acceleration optimization result and the current acceleration optimization result are the same, then the current acceleration optimization result is used as calibration data for at least one data source.

[0042] Specifically, such as Figure 4 As shown in the embodiment of this application, at least one data source is obtained and input into the ACC functional model to obtain evaluation indicators. Based on these indicators, the acceleration is optimized to obtain the optimization result. The optimization precision is retained to two decimal places. Acceleration optimization for this data source ends when two consecutive accelerations are consistent, and its final value is used as the acceleration calibration data corresponding to that data source. Once all data sources have completed acceleration parameter optimization and the entire acceleration optimization and calibration process is complete, the corresponding acceleration can be retrieved for different acceleration processes by looking up a table and substituting it into the ACC functional model.

[0043] According to the ACC data-driven optimization method proposed in this application, by acquiring at least one data source and inputting it into a preset ACC functional model, acceleration function evaluation indicators are obtained. The gain values ​​of acceleration, acceleration time, and steady-state time indicators are calculated respectively to obtain acceleration indicator gain, acceleration time indicator gain, and steady-state time indicator gain. Based on the acceleration indicator gain, acceleration time indicator gain, and steady-state time indicator gain, a comprehensive acceleration gain is obtained, and acceleration optimization is performed based on the comprehensive acceleration gain. This solves the problem in related technologies where ACC acceleration calibration and optimization data acquisition is cumbersome and cannot cover all scenarios. By adopting a data-driven approach for optimization and parameter tuning, it covers most operating conditions. It automatically associates data and automatically tunes parameters based on evaluation indicators, eliminating the need for extensive testing to acquire data and greatly saving optimization time.

[0050] Optionally, in some embodiments, after acceleration optimization based on the acceleration composite gain, the optimization module 300 further includes an acquisition unit and a calibration unit.

[0057] Optionally, in some embodiments, the optimization module 300 includes a third computing unit.
