Description

Technical Field

[0001] The present invention relates to the field of engine technology, and in particular to an engine adaptive calibration method, device, electronic equipment and storage medium. Background Art

[0002] The calibration of engine parameters relies heavily on the subjective vibration evaluation results of individual or batch drivers, which may not be representative and universal compared to the large number of drivers using mass-produced products.

[0003] Due to the differences in drive shafts, gearboxes, and engines of different types of vehicles such as tractors and engineering vehicles, as well as factors such as vehicle aging and consistency in manufacturing and assembly of transmission system clearances, the vibration level of the vehicle cannot be effectively controlled throughout its life cycle. The calibration parameters used to achieve the same vibration evaluation results also vary greatly, making it impossible to take into account the impact of transmission gear clearance on the longitudinal vibration of the cab, and thus making it impossible to comprehensively balance the dynamics and vibration comfort of the vehicle throughout its life cycle. Summary of the Invention

[0004] In view of this, it is necessary to provide an engine adaptive calibration method, device, electronic equipment and storage medium to solve the technical problem that the existing engine calibration method cannot take into account the influence of transmission gear clearance on the longitudinal vibration of the cab.

[0005] In order to solve the above problems, the present invention provides an engine adaptive calibration method, comprising:

[0006] Obtain the vibration dose value and impact peak value of the engine;

[0007] determining an engine vibration factor parameter based on a sum of the vibration dose value and the impact peak value;

[0008] determining an engine target torque limit rate value that matches the engine vibration factor parameter;

[0009] When the vehicle transmission clearance is greater than a preset normal value, the actual engine torque limit rate value is adjusted to the engine target torque limit rate value.

[0010] In a possible implementation, obtaining a vibration dose value of an engine includes:

[0012] The vibration dose value of the engine is obtained based on the average value of the plurality of engine speed fluctuation cycles and the root mean square value of the speed acceleration.

[0013] In one possible implementation, the calculation formula for the vibration dose value of the engine is:

[0014] C = [(1.4× a )×4× b ]×1 / 4

[0015] in, a is the RMS value of the engine speed acceleration during the engine speed fluctuation period, b is the average value of several engine speed fluctuation cycles, C is the vibration dose value of the engine.

[0016] In a possible implementation, obtaining the impact peak value of the engine includes:

[0017] Get engine speed acceleration;

[0018] Based on the absolute value of the derivative of the engine speed acceleration, a surge peak of the engine is determined.

[0019] In a possible implementation, adjusting the actual engine torque limit rate value to the target engine torque limit rate value includes:

[0020] In a current driving cycle, if the number of times the current engine vibration factor parameter exceeds the current engine vibration factor parameter level reaches a target number, in a next driving cycle, the actual engine torque limit rate value is adjusted to the target engine torque limit rate value.

[0021] In a possible implementation, when the vehicle transmission clearance is greater than a preset normal value, the engine target torque limit rate values ​​are divided into: a first gear limit rate value, a second gear limit rate value, and a third gear limit rate value from small to large;

[0022] When the vehicle transmission clearance is greater than the preset normal value, the engine vibration factor parameters are divided into: first-level vibration factor parameters, second-level vibration factor parameters and third-level vibration factor parameters;

[0023] Among them, the first-level limit rate value corresponds to the first-level vibration factor parameter, the second-level limit rate value corresponds to the second-level vibration factor parameter, and the third-level limit rate value corresponds to the third-level vibration factor parameter.

[0024] In one possible implementation, the engine adaptive calibration method further includes:

[0025] When the actual torque limit rate value of the engine is adjusted with the third gear limit rate value as the target, and the actual torque limit rate value of the engine is not adjusted to the normal torque limit rate value of the engine after the target time is maintained, a reminder to inspect the vehicle transmission clearance is issued.

[0026] On the other hand, the present invention also provides an engine adaptive calibration device, comprising:

[0027] A data acquisition module is used to obtain the vibration dose value and impact peak value of the engine;

[0028] a vibration factor calculation module, configured to determine an engine vibration factor parameter based on the sum of the vibration dose value and the impact peak value;

[0029] a rate limiting calculation module, configured to determine an engine target torque rate limiting value that matches the engine vibration factor parameter;

[0030] The rate limit adjustment module is used to adjust the actual engine torque rate limit value to the engine target torque rate limit value when the vehicle transmission clearance is greater than a preset normal value.

[0031] In another aspect, an electronic device includes a memory and a processor, wherein:

[0032] The memory is used to store programs;

[0033] The processor is coupled to the memory and is configured to execute the program stored in the memory to implement the steps of any one of the above-mentioned engine adaptive calibration methods.

[0034] On the other hand, a non-transitory computer-readable storage medium stores a computer program thereon, and when the computer program is executed by a processor, the steps of the engine adaptive calibration method as described in any one of the above are implemented.

[0035] The beneficial effects of the above-described implementation are as follows: the engine adaptive calibration method, device, electronic device, and storage medium provided by the present invention determine an engine vibration factor parameter based on the sum of the engine vibration dose value and the impact peak value; determine an engine target torque limit rate value that matches the engine vibration factor parameter; and, when the vehicle transmission clearance is greater than a preset normal value, adjust the actual engine torque limit rate value to the engine target torque limit rate value. Because vehicle transmission clearance exceeding the normal value affects the longitudinal vibration of the cab, that is, affects the vibration perception within the cab, and different torque rate limit parameters and different vibration factor parameters correspond to different vibration perceptions, the present invention adjusts based on the engine target torque limit rate value that matches the engine vibration factor parameter, thereby reducing the impact of transmission gear clearance on the longitudinal vibration of the cab, thereby resolving the technical problem that existing engine calibration methods fail to take into account the impact of transmission gear clearance on the longitudinal vibration of the cab.

It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0045] The present invention provides an engine adaptive calibration method, device, electronic device and storage medium, which are described below respectively.

[0046] like Figure 1 As shown, the present invention provides an engine adaptive calibration method, comprising:

[0047] S101, obtaining the vibration dose value and impact peak value of the engine;

[0048] S102, determining an engine vibration factor parameter based on the sum of the vibration dose value and the impact peak value;

[0049] S103, determining an engine target torque limit rate value that matches the engine vibration factor parameter;

[0050] S104: When the vehicle transmission clearance is greater than a preset normal value, the actual engine torque limit rate value is adjusted to the engine target torque limit rate value.

[0051] It can be understood that the engine adaptive calibration method provided by the present invention establishes a performance function Y (i.e., engine vibration factor) that reflects the longitudinal vibration perception of the cab, corresponding to different levels of engine torque rate limit parameter X. The numerical values ​​of the function Y correspond to driving vibration perception levels ranging from basically acceptable, acceptable, and satisfactory, and the corresponding power response time relationship is shown in Table 1:

[0052] Table 1: Correspondence between torque rate limit parameters, vibration factor parameters, vibration perception and dynamic response time

[0053]

[0054] The method provided by the present invention determines an engine vibration factor parameter based on the sum of an engine vibration dose value and an impact peak value; determines an engine target torque limit rate value that matches the engine vibration factor parameter; and, when vehicle transmission clearance exceeds a preset normal value, adjusts the actual engine torque limit rate value to the engine target torque limit rate value. Because vehicle transmission clearance exceeding the normal value affects the longitudinal vibration of the cab, i.e., the vibration perception within the cab, and different torque limit rate parameters and vibration factor parameters correspond to different vibration perceptions, the present invention adjusts the engine target torque limit rate value based on the engine vibration factor parameter, thereby reducing the impact of transmission gear clearance on cab longitudinal vibration, thereby resolving the technical problem that existing engine calibration methods fail to account for the impact of transmission gear clearance on cab longitudinal vibration.

[0055] In some embodiments, obtaining a vibration dose value of an engine includes:

[0056] Obtaining an average value of a plurality of engine speed fluctuation cycles and a root mean square value of the speed acceleration within the engine speed fluctuation cycle;

[0057] The vibration dose value of the engine is obtained based on the average value of the plurality of engine speed fluctuation cycles and the root mean square value of the speed acceleration.

[0058] In some embodiments, the vibration dose value of the engine is calculated as follows:

[0059] C = [(1.4× a )×4× b ]×1 / 4

[0060] in, a is the RMS value of the engine speed acceleration during the engine speed fluctuation period, b is the average value of several engine speed fluctuation cycles, C is the vibration dose value of the engine.

[0061] In some embodiments, obtaining the impact peak of the engine includes:

[0062] Get engine speed acceleration;

[0063] Based on the absolute value of the derivative of the engine speed acceleration, a surge peak of the engine is determined.

[0064] It is understood that the engine vibration factor is defined as the sum of the engine vibration dose value and the impact peak value. The definitions of the engine vibration dose value and the impact peak value are as follows:

[0065] Vibration dose value = [(1.4× a )×4× b ]×1 / 4;

[0066] b： The average value of several engine speed fluctuation cycles;

[0067] a： The root mean square value of the engine speed acceleration during the engine speed fluctuation period;

[0068] Impact peak: The absolute value of the acceleration derivative of the engine speed.

[0069] In some embodiments, adjusting the actual engine torque limit rate value to the target engine torque limit rate value includes:

[0070] In a current driving cycle, if the number of times the current engine vibration factor parameter exceeds the current engine vibration factor parameter level reaches a target number, in a next driving cycle, the actual engine torque limit rate value is adjusted to the target engine torque limit rate value.

[0071] In some embodiments, when the vehicle transmission clearance is greater than a preset normal value, the engine target torque limit rate value is divided into: a first gear limit rate value, a second gear limit rate value, and a third gear limit rate value from small to large;

[0072] When the vehicle transmission clearance is greater than the preset normal value, the engine vibration factor parameters are divided into: first-level vibration factor parameters, second-level vibration factor parameters and third-level vibration factor parameters;

[0073] Among them, the first-level limit rate value corresponds to the first-level vibration factor parameter, the second-level limit rate value corresponds to the second-level vibration factor parameter, and the third-level limit rate value corresponds to the third-level vibration factor parameter.

[0074] In some embodiments, the engine adaptive calibration method further includes:

[0075] When the actual torque limit rate value of the engine is adjusted with the third gear limit rate value as the target, and the actual torque limit rate value of the engine is not adjusted to the normal torque limit rate value of the engine after the target time is maintained, a reminder to inspect the vehicle transmission clearance is issued.

[0076] In some embodiments, the present invention provides an engine adaptive calibration method comprising the following steps:

[0077] 1. On vehicles with different levels of transmission gear clearance, verify and determine the corresponding vibration factor parameter values ​​Y0, Y1, Y2, and Y3 when the longitudinal vibration perception evaluation is satisfactory, acceptable, basically acceptable, and unacceptable.

[0078] 2. On vehicles with vibration factor parameter values ​​of Y1, Y2, and Y3, adjust the engine torque limit rate value to X1, X2, and X3 respectively to ensure that the vibration factor parameter returns to the standard value Y0.

[0079] 3. The vehicle's deceleration function is turned off by default when it leaves the factory, and the deceleration counter is set to 0 to ensure optimal power responsiveness.

[0080] 4. As the vehicle runs in and the gear clearance of the transmission increases, once the vibration factors of each speed exceed the vibration evaluation factors Y1, Y2, and Y3 of each level successively or separately for a maximum number of times, the corresponding torque limit rate schemes X1, X2, and X3 will be automatically activated in the next driving cycle.

[0081] 5. Once the most stringent torque limit rate scheme X3 is activated, if the vibration factor cannot be controlled below the standard value Y0, the driver will be reminded to return to the service station to inspect the transmission system gear clearance and reset the torque reduction function.

[0082] The engine adaptive calibration method provided by the present invention has the following key technical points:

[0083] 1. The vehicle automatically identifies when to activate the deceleration function, thereby achieving the greatest possible balance between the vehicle's dynamics and vibration comfort throughout its life cycle.

[0084] 2. Through statistical analysis of the mileage distribution characteristics of vibration comfort of a large number of vehicles, further proactive measures can be taken to improve vehicle competitiveness.

[0085] The engine adaptive calibration method provided by the present invention realizes adaptive calibration of control parameters through an algorithm for evaluating longitudinal vibration during vehicle acceleration and deceleration, and is applied to the continuous optimization of vibration perception throughout the life cycle of vehicles with different transmission system configurations, manufacturing consistency, and working durability.

[0086] Compared with the existing scheme of manually calibrating engine parameters, the engine adaptive calibration method provided by the present invention establishes a correspondence between different transmission gear clearances, subjective evaluation and objective quantification of longitudinal vibration levels, and torque rate limitation levels.

[0087] Compared with existing technical solutions, the engine adaptive calibration method provided by the present invention can take into account the impact of different ranges of transmission gear clearance on the longitudinal vibration of the cab to the greatest extent during the performance development stage and user use stage by dynamically identifying the vibration evaluation level and switching the torque rate limiting scheme.

Because vehicle transmission clearance exceeding the normal value affects the longitudinal vibration of the cab, that is, the vibration perception within the cab, and different torque rate limit parameters and vibration factor parameters correspond to different vibration perceptions, the present invention adjusts the engine based on the target engine torque rate limit value that matches the engine vibration factor parameter, thereby reducing the impact of transmission gear clearance on the longitudinal vibration of the cab.
