[0023] In order to make the objectives, technical solutions and advantages of the present disclosure clearer, the technical solutions in the present disclosure will be described clearly and completely below with reference to the drawings in the present disclosure. Obviously, the described embodiments are some embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without any creative effort fall within the protection scope of the present disclosure.

[0024] Figure 1 is a flowchart illustrating a method for adjusting an accelerator pedal opening degree according to an embodiment of the present disclosure.

[0025] As Figure 1 shown, the method for adjusting an accelerator pedal opening degree according to an embodiment of the present disclosure specifically includes the following steps.

[0026] Step 101: Real-time acquisition of an accelerator signal and a current vehicle speed.

[0027] In an embodiment of the present disclosure, the accelerator signal refers to an instruction signal given by the driver through the accelerator pedal, which is usually provided by an accelerator pedal position sensor. The sensor can detect the position change of the accelerator pedal and convert it into an electrical signal. These signals reflect the driver's operation intention of the accelerator pedal. During the process of low-speed driving of the vehicle, the accelerator signal and the current vehicle speed need to be monitored in real time, so as to respond to the driver's operation intention in time.

[0028] Step 102: Based on the accelerator signal, determine whether the current accelerator pedal opening degree is not less than the minimum limit value of the accelerator pedal opening degree.

[0029] In one embodiment of the present disclosure, the current accelerator pedal opening degree refers to the actual opening degree of the accelerator pedal at present, usually expressed in percentage, 0% indicating that the accelerator pedal is fully closed, and 100% indicating that the accelerator pedal is fully opened. The minimum limit value of the accelerator pedal opening degree is a preset threshold of the accelerator pedal opening degree, which is used to distinguish the slight movement of the accelerator pedal (which may be unintentional or not required to respond) and the actual acceleration request. According to the accelerator signal, the current accelerator pedal opening degree can be determined, so that the size relationship between the current accelerator pedal opening degree and the minimum limit value of the accelerator pedal opening degree can be determined.

[0030] Step 103: In the case that the current accelerator pedal opening degree is not less than the minimum limit value, based on the current accelerator pedal opening degree, the current vehicle speed and the accelerator pedal opening degree change step mapping table, determine the accelerator pedal opening degree change step value.

[0031] Step 104: Based on the accelerator pedal opening degree change step value, adjust the current accelerator pedal opening degree step by step for multiple times to output the target accelerator pedal opening degree; wherein the accelerator pedal opening degree change step mapping table contains the corresponding relationship among the current accelerator pedal opening degree, the current vehicle speed and the accelerator pedal opening degree change step value; the accelerator pedal opening degree change step value is calibrated according to different accelerator opening degrees and vehicle speeds, and is used to determine the amplitude of each adjustment of the accelerator pedal.

[0032] In one embodiment of the present disclosure, the accelerator pedal opening degree change step mapping table is a preset data table, which is obtained by calibrating the vehicle and reflects the accelerator pedal opening degree change step value that should be used at different accelerator pedal opening degrees and vehicle speeds. It contains the correspondence between the current accelerator pedal opening degree, the current vehicle speed and the accelerator pedal opening degree change step value. The accelerator pedal opening degree change step value refers to the magnitude of each adjustment of the accelerator pedal opening degree, which affects the power output and response speed of the vehicle, and is calibrated according to different accelerator opening degrees and vehicle speeds. For example, the calibration process usually involves measuring the actual power output of the vehicle under specific test conditions, such as different vehicle speeds and accelerator pedal opening degrees, and then adjusting the accelerator pedal opening degree change step value based on these data to ensure that the power output of the vehicle matches the driver's operating intention. The target accelerator pedal opening degree refers to the desired accelerator pedal opening degree value, which can be the next accelerator pedal opening degree that needs to adjust the current accelerator pedal opening degree output based on the driver's requested accelerator pedal opening degree, vehicle state or road and environmental conditions (such as uphill or downhill). When the current accelerator pedal opening degree is not less than the minimum limit of the accelerator pedal opening degree, the accelerator pedal opening degree change step value is determined according to the current accelerator pedal opening degree, the current vehicle speed and the accelerator pedal opening degree change step mapping table, so that the current accelerator pedal opening degree is adjusted step by step multiple times using the accelerator pedal opening degree change step value, that is, the current accelerator pedal opening degree is changed in a stepped manner to output the target accelerator pedal opening degree.

[0033] In summary, according to the technical scheme provided by the embodiment of the present disclosure, by acquiring the accelerator signal and the current vehicle speed in real time, when the current accelerator pedal opening degree is not less than the minimum limit of the accelerator pedal opening degree, the accelerator pedal opening degree change step value is determined according to the current accelerator pedal opening degree, the current vehicle speed and the accelerator pedal opening degree change step mapping table, and the current accelerator pedal opening degree is adjusted according to the accelerator pedal opening degree change step value to output the target accelerator pedal opening degree, which realizes the adjustment of the accelerator pedal opening degree in a stepped manner, avoids the vehicle from being accelerated due to the direct response to the driver's demand and gives the corresponding accelerator pedal opening degree, makes the driving process more stable and improves the driving comfort.

[0034] Further, the accelerator pedal opening degree change step mapping further comprises a correspondence between the current vehicle speed and the vehicle speed level, and a correspondence between the current accelerator pedal opening degree and the accelerator pedal opening degree; in the case that the previous accelerator pedal opening degree is not less than the minimum limit value, determining the accelerator pedal opening degree change step value based on the current accelerator pedal opening degree, the current vehicle speed and the accelerator pedal opening degree change step mapping table comprises: in the case that the previous accelerator pedal opening degree is not less than the minimum limit value, determining the accelerator pedal opening degree level corresponding to the current accelerator pedal opening degree based on the current accelerator pedal opening degree; determining the vehicle speed level corresponding to the current vehicle speed based on the current vehicle speed; and determining the accelerator pedal opening degree change step value based on the accelerator pedal opening degree level and the vehicle speed level by searching the accelerator pedal opening degree change step mapping table.

[0035] In one embodiment of the present disclosure, the vehicle speed level refers to the vehicle speed level divided according to the size of the vehicle speed during the vehicle process. The accelerator pedal opening degree level refers to the size level of the pedal opening degree when the driver steps on the accelerator pedal. The vehicle speed is divided into several levels, and each level represents a vehicle speed range. The accelerator pedal opening degree is divided into several levels, and each level represents an accelerator pedal opening degree range. For each combination of vehicle speed level and accelerator pedal opening degree level, there is a corresponding accelerator pedal opening degree change step value. This value represents the magnitude of the accelerator pedal opening degree adjustment under the given vehicle speed and accelerator pedal opening degree. According to the current accelerator pedal opening degree, the accelerator pedal opening degree level to which it belongs is searched. According to the current vehicle speed, the vehicle speed level to which it belongs is searched. The determined vehicle speed level and accelerator pedal opening degree level are used as indexes to search the corresponding accelerator pedal opening degree change step value in the accelerator pedal opening degree change step mapping table.

[0036] For example, a plurality of vehicle speed thresholds and a plurality of accelerator pedal opening degree thresholds are set, different vehicle speed levels can be divided according to the plurality of vehicle speed thresholds, and different accelerator pedal opening degree levels can be divided according to the plurality of accelerator pedal opening degree thresholds. The collected data is analyzed and processed to find the relationship between the accelerator pedal opening degree change step value and the accelerator pedal opening degree level and the vehicle speed level. According to the analysis result, the accelerator pedal opening degree change step value is calibrated and optimized to ensure that the vehicle can obtain the best response and performance under different working conditions.

[0037] In summary, according to the technical scheme provided by the embodiments of the present disclosure, in the case that the previous accelerator pedal opening degree is not less than the minimum limit value, the accelerator pedal opening degree change step value is determined through the above steps, and then this step value is used to adjust the current accelerator pedal opening degree in a stepwise manner. In this way, the acceleration process of the vehicle will be more stable, and the vehicle will not be accelerated too fast due to the direct response to the driver's demand.

[0038] Further, based on the accelerator pedal opening degree change step value, the current accelerator pedal opening degree is adjusted step by step multiple times, and the target accelerator pedal opening degree is output, including: determining the difference between the current accelerator pedal opening degree and the target accelerator pedal opening degree; if the difference is not an integer multiple of the accelerator pedal opening degree change step value, then ignore the part less than one accelerator pedal opening degree change step value, and based on the accelerator pedal opening degree change step value, the current accelerator pedal opening degree is adjusted step by step multiple times, so that the actual output accelerator pedal opening degree is not greater than the target accelerator pedal opening degree.

[0039] In one embodiment of the present disclosure, the target accelerator pedal opening degree can be the next accelerator pedal opening degree determined based on the driver's operation intention (signal given by the accelerator pedal). By determining the difference between the current accelerator pedal opening degree and the target accelerator pedal opening degree, it is determined whether the current accelerator opening degree can be adjusted by a complete accelerator pedal opening degree change step value to reach the preset next accelerator pedal opening degree. If the difference is not an integer multiple of the accelerator pedal opening degree change step value, it means that the preset next accelerator pedal opening degree cannot be reached directly by one or more complete step adjustments. In this case, the part less than one accelerator pedal opening degree change step value is ignored, i.e. only the integer multiple of the accelerator pedal opening degree change step adjustment is made to the current accelerator pedal opening degree, so that the actual output accelerator pedal opening degree is not greater than the target accelerator pedal opening degree. This can ensure that the adjustment process is stepwise, avoiding small and discontinuous adjustments, thereby maintaining the smoothness of vehicle acceleration. Ensuring that the actual output accelerator pedal opening degree does not exceed the target accelerator pedal opening degree is to maintain the smoothness and controllability of vehicle acceleration.

[0040] In practical applications, this process ensures that the adjustment of the accelerator pedal opening degree is smooth and controllable. It avoids the problem of vehicle sudden movement or unstable acceleration caused by directly responding to the driver's demand. Through the stepwise adjustment method, a smoother transition to the desired accelerator pedal opening degree can be achieved, thereby improving the comfort and safety of driving.

[0041] In summary, according to the technical scheme provided by the embodiment of the present disclosure, the adjustment strategy based on the mapping table and the step value ensures that the adjustment of the accelerator pedal opening degree not only meets the driver's operation intention, but also maintains the smooth acceleration of the vehicle.

[0042] Further, the method comprises: determining whether the opening degree change rate of the accelerator pedal between the current accelerator pedal opening degree and the last accelerator pedal opening degree is less than the minimum opening degree change rate of the accelerator pedal, when the current accelerator pedal opening degree is not less than the minimum limit value; adjusting the current accelerator pedal opening degree to the last accelerator pedal opening degree when the opening degree change rate is less than the minimum opening degree change rate; determining the accelerator pedal opening degree change step value based on the adjusted current accelerator pedal opening degree, the current vehicle speed and the accelerator pedal opening degree change step mapping table; and adjusting the adjusted current accelerator pedal opening degree in steps based on the accelerator pedal opening degree change step value, and outputting a target accelerator pedal opening degree.

[0043] In one embodiment of the present disclosure, the opening degree change rate refers to the change rate between the current accelerator pedal opening degree and the last accelerator pedal opening degree. The minimum opening degree change rate of the accelerator pedal is a preset threshold value for distinguishing between the slight operation (possibly unintentional or not requiring response) of the driver and the obvious acceleration or deceleration request. When the opening degree change rate is less than the minimum opening degree change rate, it can be considered that the operation of the driver is slight and no significant adjustment of the accelerator pedal opening degree is required. In the case where the current accelerator pedal opening degree is not less than the minimum limit value, the opening degree change rate between the current accelerator pedal opening degree and the last accelerator pedal opening degree is determined. The opening degree change rate is compared with the minimum opening degree change rate. When the opening degree change rate is less than the minimum opening degree change rate, the current accelerator pedal opening degree is adjusted to the last accelerator pedal opening degree. If the opening degree change rate is less than the minimum opening degree change rate, it means that the operation of the driver is slight, possibly unintentional or not requiring response. In this case, the current accelerator pedal opening degree is adjusted to the last accelerator pedal opening degree to maintain the smooth acceleration and throttle stability of the vehicle. After adjusting the current accelerator pedal opening degree, the accelerator pedal opening degree change step value is determined again using the adjusted current accelerator pedal opening degree, the current vehicle speed and the accelerator pedal opening degree change step mapping table, and the adjusted current accelerator pedal opening degree is adjusted step by step multiple times using the determined accelerator pedal opening degree change step value, and then a target accelerator pedal opening degree output is output for controlling the acceleration process of the vehicle.

[0044] Exemplarily, the minimum limit value of the accelerator pedal opening degree change rate is set to 0.5. In actual application, the above process ensures that the adjustment of the accelerator pedal opening degree is smooth and controllable, especially when the driver performs a slight operation. By introducing the opening degree change rate and the minimum opening degree change rate, the intention of the driver can be more accurately identified and adjusted accordingly. This helps to improve the comfort and safety of driving, and at the same time reduces the problem of vehicle movement or unstable acceleration caused by the slight operation of the driver.

[0045] Further, the adjusted current accelerator pedal opening degree can be used to find the accelerator pedal opening degree level it belongs to. According to the current vehicle speed, the vehicle speed level it belongs to can be found. The determined vehicle speed level and accelerator pedal opening degree level are used as indexes to find the corresponding accelerator pedal opening degree change step value in the accelerator pedal opening degree change step mapping table. By determining the difference between the adjusted current accelerator pedal opening degree and the target accelerator pedal opening degree, it can be judged whether the adjusted current accelerator pedal opening degree can be adjusted to the target accelerator pedal opening degree through a complete accelerator pedal opening degree change step value. If the difference is not an integer multiple of the accelerator pedal opening degree change step value, it means that the target accelerator pedal opening degree cannot be directly reached through one or more complete step adjustments. In this case, the part less than one accelerator pedal opening degree change step value is ignored, i.e. only an integer multiple of the accelerator pedal opening degree change step adjustment is made to the adjusted current accelerator pedal opening degree, so that the actual output accelerator pedal opening degree is not greater than the target accelerator pedal opening degree. This can ensure that the adjustment process is stepwise, avoiding small and discontinuous adjustments, thereby maintaining the smoothness of vehicle acceleration. Ensuring that the actual output accelerator pedal opening degree does not exceed the preset value is to maintain the smoothness and controllability of vehicle acceleration.

[0046] Further, in the case where the current accelerator pedal opening degree is less than the minimum limit value, the current accelerator pedal opening degree is adjusted to 0.

[0047] In an embodiment of the present disclosure, during low-speed driving of the vehicle, small accelerator pedal opening degree cannot meet the power demand of the vehicle (such as a commercial vehicle). Therefore, when the current accelerator pedal opening degree is less than the minimum limit value, the current accelerator opening degree is corrected to 0 to achieve energy saving effect.

[0048] In summary, according to the technical solution provided by the embodiment of the present disclosure, through the above method, the fuel consumption and transient working condition of the transmission caused by small accelerator pedal opening degree during low-speed driving of the vehicle can be avoided.

[0049] To illustrate in detail the method for adjusting the accelerator pedal opening degree provided by the present disclosure, reference is made to Figure 2 , Figure 2 is a further illustration of the method for adjusting the accelerator pedal opening degree according to the embodiment of the present disclosure.

[0050] Step 201: In the low-speed mode, the driver requests the accelerator opening degree, and the accelerator signal and the current vehicle speed need to be acquired in real time.

[0051] Step 202: Determine whether the current accelerator pedal opening degree is less than the accelerator pedal opening degree threshold (i.e. the minimum limit value of the accelerator pedal opening degree). If yes, go to step 211, otherwise go to step 203.

[0052] Since the small throttle cannot meet the power demand of commercial vehicles, and will cause power loss, in the low speed mode, according to the driving style of the driver's requested throttle opening, the throttle signal and the current vehicle speed are obtained in real time, according to the throttle signal, the current throttle pedal opening is determined, and the current throttle pedal opening is preliminarily processed. Determine whether the current throttle pedal opening is less than the throttle pedal opening threshold.

[0053] Enter step 203:

[0054] Step 203: Determine whether the throttle pedal opening rate is less than the throttle pedal opening rate threshold APP_r2_C (i.e. the minimum limit of the aforementioned throttle pedal opening rate), if yes, enter step 207, otherwise enter step 204.

[0055] Specifically, set the throttle pedal opening rate threshold APP_r2_C = 0.5, determine the current throttle pedal opening and the last throttle pedal opening, and determine whether the throttle pedal opening rate is less than the throttle pedal opening rate threshold.

[0056] Enter step 204:

[0057] Step 204: Find the throttle pedal opening step value under different vehicle speed levels and throttle pedal opening levels.

[0058] Specifically, 1) the vehicle speed is divided into three levels according to the following different thresholds:

[0059] Vehicle speed threshold 1: DrvDem_vAPPRange1_C

[0060] Vehicle speed threshold 2: DrvDem_vAPPRange2_C

[0061] 2) The throttle pedal opening is divided into four levels according to the following different thresholds:

[0062] Throttle pedal opening threshold 1: DrvDem_rAPPRange1_C

[0063] Throttle pedal opening threshold 2: DrvDem_rAPPRange2_C

[0064] Throttle pedal opening threshold 3: DrvDem_rAPPRange3_C

[0065] 3) According to the vehicle speed level and the throttle pedal opening level, the Map table (i.e. the aforementioned throttle pedal opening step value mapping table) is inquired to determine the throttle change step (i.e. the aforementioned throttle pedal opening step value).

[0066] Step 205: Discard the throttle pedal opening step value that does not meet the requirement.

[0067] Specifically, the current accelerator pedal opening is processed according to the accelerator change step obtained by the table lookup.

[0068] When the difference between the current accelerator pedal opening and the preset next accelerator pedal opening does not satisfy the integer multiple of the accelerator pedal opening change step value, the part that does not satisfy one accelerator pedal opening change step value is discarded, and the current accelerator pedal opening is adjusted in a stepwise manner according to the corresponding step value of the accelerator change step obtained by the table lookup each time the accelerator changes, so as to avoid that the actual output target accelerator pedal opening is greater than the target accelerator pedal opening (i.e., the accelerator requested by the driver).

[0069] Step 206: output the next accelerator pedal opening.

[0070] Step 207: keep the previous accelerator pedal opening.

[0071] Specifically, when the accelerator pedal opening change rate is less than the accelerator pedal opening change rate threshold, the current accelerator pedal opening is adjusted to the last accelerator pedal opening.

[0072] Step 208: look up the accelerator pedal opening change step value under different vehicle speed levels and accelerator pedal opening levels.

[0073] Specifically, 1) the vehicle speed is divided into three levels according to the following different thresholds:

[0074] Vehicle speed threshold 1: DrvDem_vAPPRange1_C

[0075] Vehicle speed threshold 2: DrvDem_vAPPRange2_C

[0076] 2) the accelerator pedal opening is divided into four levels according to the following different thresholds:

[0077] Accelerator pedal opening threshold 1: DrvDem_rAPPRange1_C

[0078] Accelerator pedal opening threshold 2: DrvDem_rAPPRange2_C

[0079] Accelerator pedal opening threshold 3: DrvDem_rAPPRange3_C

[0080] 3) the accelerator change step (i.e., the aforementioned accelerator pedal opening change step value) is determined according to the vehicle speed level and the accelerator pedal opening level by looking up the Map table (i.e., the aforementioned accelerator pedal opening change step value mapping table).

[0081] Step 209: discard the part that does not satisfy one accelerator pedal opening change step value.

[0082] Specifically, the current accelerator pedal opening is processed according to the accelerator change step obtained by table lookup.

[0083] When the difference between the last accelerator pedal opening and the target accelerator pedal opening does not satisfy the integer multiple of the accelerator pedal opening change step value, the part that does not satisfy the accelerator pedal opening change step value is discarded, the accelerator change step obtained by table lookup is used, and the last accelerator pedal opening is adjusted step by step multiple times according to the corresponding step value each time the accelerator changes, so as to avoid that the actually output accelerator pedal opening is greater than the target accelerator pedal opening (i.e., the accelerator requested by the driver).

[0084] Step 210: output the next accelerator pedal opening.

[0085] Step 211: correct the current accelerator pedal opening to 0.

[0086] The accelerator is de-bounced, specifically, the accelerator opening less than the accelerator pedal opening threshold (APP_r1_C) is corrected to 0, achieving energy saving effect.

[0087] Figure 3 is a functional block diagram of a system for adjusting an accelerator pedal opening according to an embodiment of the present disclosure. As Figure 3 shown, the system 300 for adjusting an accelerator pedal opening according to an embodiment of the present disclosure includes a collection module 301, an accelerator pedal opening verification module 302, a step value determination module 303, and an accelerator pedal adjustment output module 304.

[0088] Specifically, the collection module 301 is configured to acquire an accelerator signal and a current vehicle speed in real time.

[0089] Specifically, the accelerator pedal opening verification module 302 is configured to determine whether the current accelerator pedal opening is not less than a minimum limit value of the accelerator pedal opening based on the accelerator signal.
