Description

Technical Field

[0001] This application relates to the field of automotive control technology, and in particular to a method, apparatus, device, and storage medium for dynamically adjusting the initial value of the accelerator pedal. Background Technology

[0002] With the development of automotive technology, the requirements for driving experience and safety are becoming increasingly stringent. As a key component for conveying driver intent, the accurate calculation of the accelerator pedal's opening degree is crucial for the vehicle's dynamic response. In automotive control, accurately identifying the accelerator pedal's free-release state (i.e., the state when the pedal is fully released) is essential for ensuring precise accelerator pedal opening degree calculations and vehicle performance.

[0003] Currently, the calculation of accelerator pedal opening generally uses a fixed initial value, which is a theoretical value derived from the average voltage of the output signal in the free-release state during multiple endurance cycle tests. This method is simple and easy to implement, but it ignores factors such as differences in sensor consistency, differences in installation location, and wear and replacement of sensors during use, all of which can cause changes in the free-release position of the accelerator pedal.

[0004] Therefore, the method of fixing the initial value has significant problems in practical applications. When the free release position of the accelerator pedal changes, the fixed value cannot accurately reflect the actual position of the pedal, resulting in the accelerator pedal having free travel or torque output even when the pedal is not pressed. This not only affects the driving experience but may also pose a safety hazard. Therefore, how to accurately calculate the accelerator pedal opening has become an urgent problem to be solved. Summary of the Invention

[0005] The purpose of this application is to provide a method, apparatus, device, and storage medium for dynamically adjusting the initial value of the accelerator pedal, aiming to solve the technical problem of how to accurately calculate the accelerator pedal opening.

[0006] To achieve the above objectives, this application proposes a method for dynamically adjusting the initial value of the accelerator pedal, the method comprising:

[0007] Acquire vehicle key status, sensor data, and vehicle speed data;

[0008] Based on the vehicle key status and the vehicle speed data, the adjustment state of the accelerator pedal initial value is obtained;

[0009] Based on the sensor data and the adjustment status, the target adjustment amount is determined, and the dynamic adjustment of the initial value of the accelerator pedal is completed.

[0010] In one embodiment, determining the adjustment state of the accelerator pedal initial value based on the vehicle key status and the vehicle speed data includes:

[0011] If the vehicle key status changes from the off state and remains in the on state, then the adjustment state of the accelerator pedal initial value is the power-on adjustment state;

[0012] If the vehicle key status changes from the open state to the closed state, the adjustment state of the accelerator pedal initial value is determined based on the vehicle speed data.

[0013] In one embodiment, determining the adjustment state of the accelerator pedal initial value based on the vehicle speed data includes:

[0014] Obtain the preset vehicle speed threshold;

[0015] The target vehicle speed is obtained based on the vehicle speed data.

[0016] If the target vehicle speed is greater than or equal to the preset vehicle speed threshold, then the adjustment state of the initial value of the accelerator pedal is the power-off adjustment state.

[0017] In one embodiment, if the target vehicle speed is greater than or equal to the preset vehicle speed threshold, before the adjustment state of the accelerator pedal initial value is the power-off adjustment state, the method further includes:

[0024] Based on the target filter value and the historical voltage value, the filter difference value is obtained.

[0025] In one embodiment, after obtaining the filter difference value based on the target filter value and the historical voltage value, the method further includes:

[0027] The target time is obtained by recording the time using the preset filter parameters;

[0028] If the filter difference value is greater than the preset voltage threshold when the target time is within the preset time interval, then the adjustment control of the accelerator pedal initial value is exited.

[0029] When the target time is within the preset time interval, if the filter difference value is less than or equal to the preset voltage threshold, the initial value of the accelerator pedal is dynamically adjusted.

[0030] In one embodiment, after dynamically adjusting the initial value of the accelerator pedal, the method further includes:

[0031] Acquire the preset limit value, initial voltage value, preset error value, and first reference adjustment value;

[0032] If the target filter value is less than the preset limit value, a fault signal is issued;

[0033] If the target filtered value is greater than the preset limit value and less than the initial voltage value, then a target difference value is obtained based on the initial voltage value and the target filtered value.

[0034] If the target difference value is greater than the preset error value, then a first target voltage value is obtained based on the initial voltage value and the reference adjustment value, and the first target voltage value is used as the initial value of the accelerator pedal.

[0035] In one embodiment, if the target vehicle speed is greater than or equal to the preset vehicle speed threshold, after the adjustment state of the accelerator pedal initial value is in the power-down adjustment state, the method further includes:

[0036] Obtain the target filter value, preset limit value, initial voltage value, preset error value, and second reference adjustment value;

[0037] If the target filtered value is greater than the initial voltage value, then a second target voltage value is obtained based on the initial voltage value and the second reference adjustment value, and the second target voltage value is used as the initial value of the accelerator pedal;

[0038] If the target filter value is less than the initial voltage value, then the adjustment control of the accelerator pedal initial value is exited.

[0039] In one embodiment, obtaining the second reference adjustment value includes:

[0040] Obtain the reference adjustment table;

[0041] The pose data is obtained based on the sensor data;

[0042] The vehicle stability performance value is obtained based on the vehicle speed data and the pose data.

[0043] A second reference adjustment value is obtained based on the vehicle stability performance value and the reference adjustment table, wherein the reference adjustment table contains the mapping relationship between the vehicle stability performance value and the second reference adjustment value.

[0044] Furthermore, to achieve the above objectives, this application also proposes a dynamic adjustment device for the initial value of the accelerator pedal, the device comprising:

[0045] The acquisition module is used to acquire vehicle key status, sensor data, and vehicle speed data.

[0046] The module is used to obtain the adjustment state of the accelerator pedal initial value based on the vehicle key status and the vehicle speed data;

[0047] The completion module is used to determine the target adjustment amount based on the sensor data and the adjustment state, and to complete the dynamic adjustment of the initial value of the accelerator pedal.

[0048] In addition, to achieve the above objectives, this application also proposes a device for dynamically adjusting the initial value of the accelerator pedal, the device comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, the computer program being configured to implement the steps of the method for dynamically adjusting the initial value of the accelerator pedal as described above.

[0049] In addition, to achieve the above objectives, this application also proposes a storage medium, which is a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by a processor, it implements the steps of the dynamic adjustment method for the initial value of the accelerator pedal as described above.

[0050] In addition, to achieve the above objectives, this application also provides a computer program product, which includes a computer program that, when executed by a processor, implements the steps of the dynamic adjustment method for the initial value of the accelerator pedal as described above.

[0051] One or more technical solutions proposed in this application have at least the following technical effects:

[0052] This application first obtains vehicle key status, sensor data, and vehicle speed data to provide the necessary information foundation for the dynamic adjustment of the accelerator pedal initial value. Next, based on the vehicle key status and vehicle speed data, it determines whether the accelerator pedal initial value needs adjustment, and the specific adjustment state, providing direction for subsequent adjustments. Finally, based on sensor data and the determined adjustment state, the target adjustment amount is calculated, and the accelerator pedal initial value is dynamically adjusted to adapt to the current vehicle state. This application can respond to changes in vehicle state in real time and dynamically adjust the accelerator pedal initial value, thereby ensuring more accurate calculation of the accelerator pedal opening and improving vehicle responsiveness and safety. This method overcomes the shortcomings of traditional fixed initial value methods in dealing with sensor changes and differences in vehicle state, making accelerator pedal control more flexible and accurate.

[0062] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0063] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0064] With the development of automotive technology, the requirements for driving experience and safety are becoming increasingly stringent. As a key component transmitting driver intent, the accurate calculation of the accelerator pedal's opening degree is crucial for the vehicle's dynamic response. In automotive control, accurately identifying the accelerator pedal's free-release state (i.e., the state when the pedal is fully released) is essential for ensuring accurate accelerator pedal opening degree calculation and vehicle performance. Currently, accelerator pedal opening degree calculation generally uses a fixed initial value, which is a theoretical value derived from the average voltage of the output signal in the free-release state during multiple endurance cycle tests. This method is simple and easy to implement, but it ignores factors such as sensor consistency differences, installation location differences, and sensor wear and replacement during use, all of which can cause changes in the accelerator pedal's free-release position.

[0065] The main solution of this application embodiment is as follows: This embodiment obtains the vehicle key status, sensor data, and vehicle speed data to provide the necessary information basis for the dynamic adjustment of the accelerator pedal initial value. Then, based on the vehicle key status and vehicle speed data, it determines whether the accelerator pedal initial value needs adjustment, and the specific state of adjustment, providing direction for subsequent adjustments. Finally, based on the sensor data and the determined adjustment state, the target adjustment amount is calculated, and the accelerator pedal initial value is dynamically adjusted to adapt to the current vehicle state. This embodiment can respond to changes in vehicle state in real time and dynamically adjust the accelerator pedal initial value, thereby ensuring more accurate calculation of the accelerator pedal opening and improving vehicle responsiveness and safety. This method solves the shortcomings of traditional fixed initial value methods in dealing with sensor changes and differences in vehicle state, making accelerator pedal control more flexible and accurate.

[0066] It should be noted that the executing entity in this application embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device or electronic control unit capable of performing the above functions. The following description uses an electronic control unit as an example to illustrate this embodiment and the subsequent embodiments.

[0067] Based on this, embodiments of this application provide a method for dynamically adjusting the initial value of the accelerator pedal, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the dynamic adjustment method for the initial value of the accelerator pedal in this application.

[0068] In this embodiment, the method for dynamically adjusting the initial value of the accelerator pedal includes steps S10 to S30:

[0069] Step S10: Obtain vehicle key status, sensor data, and vehicle speed data;

[0070] It's important to note that the vehicle key status can be the ignition switch status, indicating the current stage of the vehicle's ignition system, such as off, ACC (accessory mode), ON, or START. Changes in the key status can trigger the ECU to execute different diagnostic and initialization procedures, setting and adjusting various vehicle systems. Sensor data can be the operating parameters of various devices; sensors convert physical quantities (such as temperature, pressure, and position) into electrical signals. The ECU reads this sensor data to understand the vehicle's current status. Vehicle speed data can be provided by the vehicle speed sensor, which can show the vehicle's real-time speed.

[0071] Understandably, by monitoring the on / off status of the vehicle key to identify the vehicle's start-up and operation phases, and by collecting information from various sensors such as engine speed, temperature, and airflow, as well as monitoring the vehicle's speed in real time through the vehicle speed sensor, this data collectively provides the ECU with comprehensive vehicle status information for precise control and adjustment.

[0072] Step S20: Based on the vehicle key status and the vehicle speed data, obtain the adjustment state of the accelerator pedal initial value;

[0073] It should be noted that the adjustment state of the accelerator pedal initial value can be determined by the electronic control unit (ECU) based on a comprehensive assessment of two parameters: the vehicle key status and vehicle speed data. The ECU decides whether and how to adjust the accelerator pedal's initial value (i.e., the voltage value corresponding to when the accelerator pedal is fully released). This state is used to determine whether the accelerator pedal initial value needs to dynamically change to adapt to current vehicle conditions, such as when the vehicle is starting, running, or off, to ensure more accurate accelerator pedal opening calculations, thereby improving vehicle performance and responsiveness.

[0074] Understandably, the initial voltage value of the accelerator pedal needs to be adjusted based on the current position of the vehicle key (such as start, run, or stop) and the actual speed of the vehicle to ensure accurate measurement of the accelerator pedal opening, thereby adapting to different driving conditions and optimizing vehicle performance.

[0075] Step S30: Determine the target adjustment amount based on the sensor data and the adjustment state, and complete the dynamic adjustment of the initial value of the accelerator pedal.

[0076] It should be noted that the target adjustment amount can be a specific value calculated by the electronic control unit (ECU) to update the initial value of the accelerator pedal, based on sensor data and the adjustment status of the accelerator pedal's initial value. This amount is derived by the ECU by comparing real-time sensor readings (such as the voltage value of the accelerator pedal position sensor) with a preset reference value or the value after the last adjustment. The purpose is to ensure that the initial position of the accelerator pedal can be accurately reflected in the ECU's control strategy, thereby achieving dynamic optimization of the accelerator pedal response characteristics.

[0077] Understandably, based on real-time sensor information and current adjustment needs, a specific adjustment value is calculated to update the initial voltage value of the accelerator pedal, ensuring that the accelerator pedal opening measurement matches the actual driving conditions, thereby achieving more precise vehicle control and response.

[0078] This embodiment provides a method for dynamically adjusting the initial value of the accelerator pedal. By acquiring vehicle key status, sensor data, and vehicle speed data, this embodiment provides the necessary information for dynamic adjustment of the accelerator pedal's initial value. Then, based on the vehicle key status and vehicle speed data, it determines whether the initial value of the accelerator pedal needs adjustment, and the specific adjustment state, providing direction for subsequent adjustments. Finally, based on the sensor data and the determined adjustment state, the target adjustment amount is calculated, and the initial value of the accelerator pedal is dynamically adjusted to adapt to the current vehicle state. This embodiment can respond to changes in vehicle state in real time and dynamically adjust the initial value of the accelerator pedal, thereby ensuring more accurate calculation of the accelerator pedal opening and improving vehicle responsiveness and safety. This method overcomes the shortcomings of traditional fixed initial value methods in dealing with sensor changes and differences in vehicle state, making accelerator pedal control more flexible and accurate.

[0079] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in Embodiment 1 above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 2 , Figure 2 This is a flowchart illustrating a second embodiment of the dynamic adjustment method for the initial value of the accelerator pedal according to this application. Step S20 of the dynamic adjustment method for the initial value of the accelerator pedal includes steps S21 to S22:

[0080] Step S21: If the vehicle key state changes from the off state and remains in the on state, the adjustment state of the accelerator pedal initial value is the power-on adjustment state.

[0081] It should be noted that the power-on adjustment state can occur when the vehicle key is switched from the off state to the on state and remains on. In this state, the electronic control unit (ECU) sets the adjustment of the accelerator pedal's initial value to require adjustment after power-on. In this state, the ECU adjusts the initial value of the accelerator pedal (i.e., the voltage value when the pedal is fully released) according to preset logic and parameters to ensure that the accelerator pedal opening can be accurately detected and responded to during vehicle start-up and operation. This adjustment is typically to compensate for changes in the initial value due to factors such as sensor aging, wear, or installation differences, in order to maintain the consistency and reliability of vehicle performance.

[0082] Understandably, when the vehicle key is switched from the off state to the on state, i.e. the vehicle is ready to start or has already started, the adjustment state of the initial value of the accelerator pedal is called the power-on adjustment state. At this time, the electronic control unit (ECU) will adjust the initial voltage value of the accelerator pedal according to sensor data and vehicle status to ensure the responsiveness and accuracy of the accelerator pedal after the vehicle starts, and to compensate for deviations caused by sensor changes or different vehicle conditions.

[0083] As an example, after the accelerator pedal initial value adjustment state is the power-on adjustment state, the process further includes: obtaining preset filtering parameters; obtaining the current voltage value and historical voltage value based on the sensor data; filtering the current voltage value based on the historical voltage value and the preset filtering parameters to obtain a target filtered value; and obtaining a filtering difference value based on the target filtered value and the historical voltage value.

[0084] The current voltage value can be the voltage value actually measured by the sensor at a certain moment, reflecting the current position of the accelerator pedal. The historical voltage value can be the voltage value after the last filtering or historical data under similar conditions, used to compare with the target filtered value to determine voltage changes. The target filtered value can be the voltage value obtained after processing the historical voltage value, the current voltage value, and preset filtering parameters through a filtering algorithm, used to reduce noise and fluctuations and more accurately reflect the actual position of the accelerator pedal. The filtering difference value can be the difference between the target filtered value and the historical voltage value, used to measure the degree of change in the voltage value after filtering. The specific calculation formula can be:

[0085] u filter(t) =(u (t) -u filter(t-1) )×k f +u filter(t-1)

[0086] Among them, u filter(t) It is the target filtered value, u filter(t-1) It is the historical voltage value, k f These are the preset filter parameters.

[0087] Specifically, first, preset filtering parameters are obtained, and then the current voltage value and historical voltage values ​​are calculated based on sensor data. Next, the current voltage value is filtered using the historical voltage value and the preset filtering parameters to obtain the target filtered value. By comparing the target filtered value and the historical voltage value, the filtering difference value is calculated.

[0088] As an example, after obtaining the filter difference value based on the target filter value and the historical voltage value, the method further includes: acquiring a preset time interval and a preset voltage threshold; obtaining a target time by acquiring the preset filter parameter recording time; if the filter difference value is greater than the preset voltage threshold when the target time is within the preset time interval, then exiting the adjustment control of the accelerator pedal initial value; if the filter difference value is less than or equal to the preset voltage threshold when the target time is within the preset time interval, then dynamically adjusting the accelerator pedal initial value.

[0089] The preset voltage threshold can be a set voltage value used to determine the stability and reliability of sensor data. When the filtered difference value of the sensor data (the difference between the filtered voltage value and the historical voltage value) exceeds this threshold, the sensor data is considered unstable or abnormal, and the adjustment control of the accelerator pedal initial value is terminated to avoid safety hazards caused by incorrect adjustments. The preset time interval can be a set time range used to determine when to check whether the filtered difference value meets the conditions for adjusting the accelerator pedal initial value. The filtered difference value is checked within a certain period to determine whether to perform dynamic adjustment of the accelerator pedal initial value. The target time can be a specific time point obtained by recording time based on preset filtering parameters. At this time point, it is checked whether the filtered difference value is within the range of the preset voltage threshold. If the filtered difference value is within the range of the preset voltage threshold (less than or equal to the preset voltage threshold), the system will dynamically adjust the accelerator pedal initial value; if it is not within this range (greater than the preset voltage threshold), the adjustment control is terminated.

[0090] Specifically, a voltage threshold and a time interval are first set. Then, at the time point when the filtering parameters are recorded (the target time), the difference between the filtered voltage value and the historical voltage value is checked (the filtering difference value). If this difference value exceeds the preset voltage threshold at the target time point, it indicates that the voltage value is unstable, and the adjustment of the accelerator pedal initial value will stop to ensure safety. If the difference value is less than or equal to the preset voltage threshold, it indicates that the voltage value is stable, and the accelerator pedal initial value will be dynamically adjusted. This ensures that the accelerator pedal initial value is dynamically adjusted when the voltage value is stable, thereby improving the accuracy and responsiveness of vehicle control.

[0091] As an example, after dynamically adjusting the initial value of the accelerator pedal, the method further includes: acquiring a preset limit value, an initial voltage value, a preset error value, and a first reference adjustment value; if the target filtered value is less than the preset limit value, issuing a fault signal; if the target filtered value is greater than the preset limit value and less than the initial voltage value, obtaining a target difference value based on the initial voltage value and the target filtered value; if the target difference value is greater than the preset error value, obtaining a first target voltage value based on the initial voltage value and the reference adjustment value, and using the first target voltage value as the initial value of the accelerator pedal.

[0092] The preset limit value can be a safety or performance parameter used to define a safe lower limit for the voltage value. If the target filter value is lower than this limit value, it may indicate a fault or abnormality. The initial voltage value can be the ideal or nominal voltage value of the accelerator pedal in the fully released position, used to compare with the actual measured value to determine whether the initial value of the accelerator pedal needs adjustment. The preset error value can be the maximum allowable error range used to determine whether the difference between the target filter value and the initial voltage value is large enough to require adjustment. The first reference adjustment value can be a pre-set adjustment parameter used to calculate a new initial value for the accelerator pedal when the target difference value exceeds the preset error value. The fault signal can be a fault signal issued when the target filter value is less than the preset limit value, indicating a possible system fault or performance problem requiring further inspection or repair. The target difference value can be the difference between the target filter value and the initial voltage value used to determine whether the initial value of the accelerator pedal needs adjustment. The first target voltage value can be a new target voltage value calculated based on the initial voltage value and the first reference adjustment value when the target difference value exceeds the preset error value; this value will be used as the updated initial value of the accelerator pedal.

[0093] Specifically, the system first checks if the target filter value is lower than a preset limit; if so, a fault signal is issued. If the target filter value is above the preset limit but lower than the initial voltage value, a target difference value is calculated. If this difference value exceeds a preset error value, indicating that adjustment is needed, a first target voltage value is calculated using the initial voltage value and a first reference adjustment value, and this is set as the new initial value for the accelerator pedal to ensure accurate accelerator pedal response.

[0094] Step S22: If the vehicle key state changes from the open state to the closed state, then the adjustment state of the accelerator pedal initial value is determined based on the vehicle speed data.

[0095] Understandably, when the vehicle key is switched from the on state to the off state and held there, that is, when the vehicle is about to be turned off or has already been turned off, the system will use vehicle speed data to determine whether the initial value of the accelerator pedal needs to be adjusted, so as to ensure that the initial position of the accelerator pedal can be accurately reflected when the vehicle is started next time, thereby maintaining the consistency and reliability of vehicle performance.

[0096] This embodiment recognizes the change when the vehicle key switches from the off state to the on state and enters a power-on adjustment state. This triggers the adjustment process for the accelerator pedal's initial value to ensure accurate accelerator pedal readings when the vehicle starts. Conversely, when the vehicle key switches from the on state to the off state, it determines whether the accelerator pedal's initial value needs adjustment based on vehicle speed data. This typically involves the vehicle's state before it is turned off, ensuring the pedal's initial position is accurate upon the next start. This embodiment intelligently determines when to adjust the accelerator pedal's initial value by monitoring changes in the vehicle key's state. When the vehicle starts (key from off to on), it proactively adjusts to accommodate possible changes in pedal position; when the vehicle is turned off (key from on to off), it determines whether adjustment is necessary based on vehicle speed data. This design ensures both performance and safety during vehicle startup, as well as consistency and reliability of the accelerator pedal across different driving cycles.

[0097] Based on the second embodiment of this application, in the third embodiment of this application, the content that is the same as or similar to that in the second embodiment described above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 3 , Figure 3 This is a flowchart illustrating the third embodiment of the dynamic adjustment method for the initial value of the accelerator pedal according to this application. Step S22 of the dynamic adjustment method for the initial value of the accelerator pedal includes steps A21 to A23:

[0098] Step A21: Obtain the preset vehicle speed threshold;

[0099] It should be noted that the preset speed threshold can be a pre-defined speed limit value used to determine whether the vehicle is in a specific operating state. When the actual vehicle speed reaches or exceeds this threshold, the vehicle is considered to be in a state where certain adjustments can be made.

[0100] Understandably, a pre-set speed threshold is used to determine whether the vehicle is in a suitable state for adjusting the initial accelerator pedal position. When the vehicle's actual speed reaches or exceeds this preset speed threshold, the vehicle is considered to be in a stable driving state, thus allowing for safe adjustment of the initial accelerator pedal position. Setting this threshold helps ensure that adjustments are not made when the vehicle is starting or in a low-speed, unstable state, thereby avoiding potential misadjustments and safety hazards.

[0101] Step A22: Obtain the target vehicle speed based on the vehicle speed data;

[0102] It should be noted that the target speed can be the vehicle's actual speed at a specific moment, measured by a vehicle speed sensor. This speed value will be compared with a preset speed threshold to determine whether the initial value of the accelerator pedal needs to be adjusted.

[0103] Understandably, real-time monitoring and recording of the vehicle's current speed, known as the "target speed," is crucial. This target speed is a key parameter in the dynamic adjustment of the accelerator pedal's initial value. It is compared with a preset speed threshold to determine if the conditions for adjusting the accelerator pedal's initial value are met. This ensures that the initial value adjustment is only performed when the vehicle reaches a certain speed, i.e., when it is in a relatively stable and safe driving state, thereby optimizing vehicle control performance and ensuring driving safety.

[0104] Step A23: If the target vehicle speed is greater than or equal to the preset vehicle speed threshold, then the adjustment state of the initial value of the accelerator pedal is the power-off adjustment state.

[0105] It should be noted that the power-off adjustment state can be a specific adjustment state that is activated when the vehicle key switches from the on state to the off state and the actual vehicle speed is greater than or equal to a preset speed threshold (i.e., valid driving control is recognized). In the power-off adjustment state, specific adjustment logic is executed to update or calibrate the initial value of the accelerator pedal. This usually occurs after the vehicle is turned off or the power is cut off to ensure that the initial position of the accelerator pedal can be accurately reflected when the vehicle is started again, thereby maintaining the consistency and reliability of vehicle performance.

[0106] Understandably, when the vehicle's actual speed (target speed) reaches or exceeds the preset safe speed standard (preset speed threshold), the adjustment state of the accelerator pedal's initial value will be set to "power-off adjustment state." This is a safety measure to ensure that the initial value of the accelerator pedal is adjusted after effective driving to optimize vehicle performance and response, while avoiding unnecessary adjustments at low speeds or in unstable conditions, thereby ensuring driving safety.

[0107] As an example, before the adjustment state of the accelerator pedal initial value is in the power-off adjustment state if the target vehicle speed is greater than or equal to the preset vehicle speed threshold, the method further includes: if the target vehicle speed is less than the preset vehicle speed threshold, then exiting the adjustment control of the accelerator pedal initial value; if the vehicle key is not in the unlocked state when the electronic control unit start signal is obtained, then exiting the adjustment control of the accelerator pedal initial value.

[0108] In this context, "on" typically refers to the vehicle's ignition switch being in a state where the vehicle can be started. This means that turning the key to the desired position or pressing the start button activates the vehicle's electronic control unit (ECU) and other related systems, preparing them for operation. In the various positions of a car key, the "on" position is usually marked "ON," indicating that the vehicle's electrical systems are powered, but the engine is not yet running. If the vehicle key is not in the "on" position, i.e., in the "off" position or another state such as ACC (adjacent control mode), then the initial accelerator pedal adjustment will not occur, as these systems only adjust when the vehicle is fully started and ready to run.

[0109] Specifically, the system continuously monitors the vehicle's actual speed, i.e., the target speed. Simultaneously, there's a preset speed threshold, which is the minimum speed required for adjusting the accelerator pedal initial value. If the target speed is below this preset threshold, the vehicle is considered unsuitable for adjustment (perhaps because it hasn't reached sufficient speed or is traveling at low speed, such as idling or stopped), and the accelerator pedal initial value adjustment control process is exited. On the other hand, when the ECU receives a start signal and prepares for self-check and initialization, it checks the vehicle key's status. If the key is not in the "ON" position (possibly "OFF," "ACC," or "LOCK"), it means the vehicle is not authorized or ready to start. In this case, for safety and logical reasons, the accelerator pedal initial value adjustment control process is also exited. In summary, these two conditions ensure that accelerator pedal initial value adjustments are only made when the vehicle is in a suitable driving or starting state, avoiding unnecessary adjustments under unsuitable conditions, thus guaranteeing the accuracy and safety of vehicle control.

[0110] As an example, if the target vehicle speed is greater than or equal to the preset vehicle speed threshold, after the adjustment state of the accelerator pedal initial value is in the power-down adjustment state, the method further includes: acquiring a target filter value, a preset limit value, an initial voltage value, a preset error value, and a second reference adjustment value; if the target filter value is greater than the initial voltage value, then a second target voltage value is obtained based on the initial voltage value and the second reference adjustment value, and the second target voltage value is used as the initial value of the accelerator pedal; if the target filter value is less than the initial voltage value, then the adjustment control of the accelerator pedal initial value is exited.

[0111] The second reference adjustment value can be a pre-set adjustment parameter used to calculate a new initial accelerator pedal value when the target filter value is greater than the initial voltage value. The second target voltage value can be a new target voltage value calculated based on the initial voltage value and the second reference adjustment value when the target filter value is greater than the initial voltage value; this value will be used as the updated initial accelerator pedal value.

[0112] Specifically, the system first acquires parameters such as the target filter value, preset limit value, initial voltage value, preset error value, and second reference adjustment value. If the target filter value exceeds the initial voltage value, a new voltage value, namely the second target voltage value, is calculated using the initial voltage value and the second reference adjustment value, and this value is set as the new initial value for the accelerator pedal. Conversely, if the target filter value is lower than the initial voltage value, no adjustment is made, and the accelerator pedal initial value adjustment control process exits directly. This is for safety reasons, to prevent actual pedal opening output without pressing the accelerator pedal upon the next power-on.

[0113] As an example, obtaining a second reference adjustment value includes: obtaining a reference adjustment table; obtaining pose data based on the sensor data; obtaining a vehicle stability performance value based on the vehicle speed data and the pose data; and obtaining a second reference adjustment value based on the vehicle stability performance value and the reference adjustment table, wherein the reference adjustment table contains a mapping relationship between the vehicle stability performance value and the second reference adjustment value.

[0114] The reference adjustment table can be a predefined table or database containing the mapping relationship between different vehicle stability performance values ​​and their corresponding reference adjustment values. This table guides how to adjust the initial value of the accelerator pedal based on the vehicle's stability performance. Position and posture data refers to data collected from sensors, typically including information such as the vehicle's position and attitude (e.g., tilt angle). Position and posture data helps the system understand the vehicle's current state, which is crucial for evaluating its stability performance. The vehicle stability performance value can be a comprehensive index calculated based on vehicle speed and position and posture data, used to evaluate the vehicle's stability and smoothness during driving. This value reflects the vehicle's driving performance under specific conditions and is an important factor in determining how to adjust the initial value of the accelerator pedal.

[0115] Specifically, first, a reference adjustment table is obtained, which defines the relationship between vehicle stability performance values ​​and corresponding adjustment values. Next, pose data collected by sensors (such as vehicle position and attitude) and vehicle speed data are used to calculate the vehicle's stability performance value, which reflects the vehicle's stability and driving smoothness in the current state. Finally, based on the calculated stability performance value, the corresponding second reference adjustment value is looked up in the reference adjustment table. This value will be used to adjust the initial value of the accelerator pedal to optimize the vehicle's driving performance and response.

[0116] This embodiment first establishes a speed standard to determine whether the vehicle is in a suitable state for adjusting the initial accelerator pedal value. Then, it monitors the vehicle's actual speed in real time for comparison with a preset speed threshold. Finally, when the vehicle speed reaches or exceeds the safety threshold, the accelerator pedal initial value adjustment state is set to "power-off adjustment state" after power is off. This embodiment intelligently determines whether to adjust the accelerator pedal initial value by monitoring vehicle speed in real time and comparing it with a preset threshold. When the vehicle is driving stably at a certain speed, it is considered to have made effective travel, thus entering the "power-off adjustment state" after power is off. This design ensures that the accelerator pedal initial value adjustment is not performed when the vehicle is starting or in a low-speed, unstable state, avoiding potential misadjustments and safety hazards, and improving driving safety and vehicle control precision.

[0117] For example, to help understand the implementation process of the dynamic adjustment method for the initial value of the accelerator pedal obtained by combining this embodiment with the above embodiment one, please refer to... Figure 4 , Figure 4 A schematic diagram illustrating the adjustment state determination of a dynamic adjustment method for the initial value of the accelerator pedal is provided, specifically:

[0118] When the vehicle key is switched from the off state to the on state and held in the on state, the ECU sets the accelerator pedal initial value adjustment state to "power-on adjustment state". This means that when the vehicle starts, the ECU will adjust the initial value of the accelerator pedal as needed to ensure that the accelerator pedal response precisely corresponds to the actual pedal position. When the vehicle key is switched from the on state to the off state and held in the off state, the ECU needs to determine whether to enter the "power-off adjustment state" based on vehicle speed data. To do this, the ECU will obtain a preset vehicle speed threshold and calculate the target vehicle speed based on the vehicle speed data. If the target vehicle speed is greater than or equal to the preset vehicle speed threshold, the ECU sets the accelerator pedal initial value adjustment state to "power-off adjustment state". This usually means that before the vehicle is turned off, if the vehicle is still running at a certain speed, the ECU will adjust the accelerator pedal initial value to ensure accuracy during the next start. If the target vehicle speed is less than the preset vehicle speed threshold, the ECU will exit the accelerator pedal initial value adjustment control and will not make any adjustment. If the ECU detects that the vehicle key is not in the on state when receiving the start signal, the ECU will also exit the accelerator pedal initial value adjustment control. This is a safety measure to ensure that unnecessary adjustments are not made when the vehicle is not started correctly or the key is not in the on state.
