[0029] This embodiment provides a message data processing method that runs on a mobile terminal, computer terminal, or similar device. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Also, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0030] Figure 2 This is a flowchart of a message data processing method according to an embodiment of this application. Figure 2 As shown, the method includes the following steps:

[0031] Step S202: If the first data array expected to be sent by the ECU at the current step length is obtained, the first judgment step is performed: determine whether the ECU meets any one of a plurality of immediate sending conditions, wherein the plurality of immediate sending conditions include a first immediate sending condition, a second immediate sending condition and a third immediate sending condition. The first immediate sending condition is that the first data array is not equal to the second data array sent by the ECU at the previous step length. The second immediate sending condition is that the ECU receives a trigger signal. The third immediate sending condition is that at least one performance parameter of the ECU is outside the threshold range corresponding to the at least one performance parameter.

[0032] Specifically, the aforementioned first data array serves as input parameters, including calibration value 1, calibration value 2, and calibration value 3. Calibration value 1 is used to calibrate the message period, calibration value 2 is used to calibrate the minimum interval time, and calibration value 3 is used to calibrate different immediate transmission conditions. Specifically, value 1 can be set to represent the immediate transmission condition being a change in the data array transmitted by the ECU with preceding and following steps; value 2 can be set to represent receiving a trigger signal from any of the following: a sensor, actuator, controller hardwire, or CAN line; and value 3 can be set to represent a certain performance parameter of the ECU exceeding or falling below a certain threshold range. By using calibration value 3 to indicate the immediate transmission condition, the function of selecting message data processing under different conditions is realized.

[0033] Step S204: If any one of the immediate transmission conditions is met at the ECU end, execute the second judgment step: determine whether the current timing time has reached the preset minimum interval time, wherein the starting timing time of the current timing time is the time when the first data array is acquired;

[0034] Specifically, if the current timing time has not reached the preset minimum interval time, the time step is increased by at least one step time based on the current timing time until the updated current timing time reaches the preset minimum interval time, and then the message data is sent, thereby enabling the message to be sent according to the minimum interval time.

[0035] Step S206: When the current timing time reaches the preset minimum interval time, trigger an enable signal to the ECU so that the ECU sends the first data array.

[0036] Specifically, when the current timing reaches the preset minimum interval, the ECU is enabled to send message data, thereby enabling the message data to be sent at the minimum time interval.

[0037] In the above method of this application embodiment, when the first data array currently being sent by the ECU is obtained, a first judgment step is first executed to determine whether the ECU meets any one of a plurality of immediate transmission conditions. If any one of the immediate transmission conditions is met, a second judgment step is then executed. By setting different immediate transmission conditions, the transmission of message data under different immediate transmission conditions can be realized. Then, a second step is executed to determine whether the current timing time has reached the preset minimum interval time. This can enable the ECU to send message data according to the minimum interval time when the required immediate transmission conditions are met. Since the above message data processing method in this application can send the most recent message according to the minimum interval time when the immediate transmission condition, such as the change in the message data sent by the ECU before and after the step size, is met, the CAN bus load rate is effectively reduced, real-time performance is improved, and software maintenance costs are reduced.

[0038] In some optional implementations, when any one of the immediate transmission conditions is met at the ECU end, the above-mentioned message data processing method in this application embodiment further includes: before determining whether the current timing time has reached the preset minimum interval time, setting a condition variable to a first preset parameter, wherein the condition variable is used to characterize whether the ECU end meets the target immediate transmission condition, and when the condition variable is the first preset parameter, the condition variable characterizes that the ECU end meets the target immediate transmission condition, and the target immediate transmission condition is one of the first immediate transmission condition, the second immediate transmission condition, and the third immediate transmission condition; when the condition variable is set to the first preset parameter, triggering an adjustment instruction, and when the first judgment step is repeatedly executed, the adjustment instruction is used to make the judgment result of the first judgment step indicate no; when the judgment result of the first judgment step indicates yes, and the judgment result of the second judgment step indicates no, sequentially executing the summation step, the first judgment step, the third judgment step, and the second judgment step at least once, until the current timing time reaches the preset minimum interval time, wherein the summation step includes: summing the current timing time with a preset step time to obtain an updated current timing time; the third judgment step includes: determining whether the condition variable is the first preset parameter.

[0039] In the above optional implementation, the first preset parameter can be set to the value 1. If the condition variable is set to 1, the condition variable indicates that the ECU meets the target immediate transmission condition; conversely, if the condition variable indicates that the ECU does not meet the target immediate transmission condition, the condition variable is set to 0.

[0040] Specifically, when the condition variable is the first preset parameter, it means that the ECU meets the immediate transmission condition. The immediate transmission condition is, for example, that the data array that the ECU expects to send in the current step size is not equal to the second data array sent by the ECU in the previous step size, or that the ECU receives a trigger signal sent by any one of the sensors, actuators, controller hardwires, and CAN lines from the other party, or that a certain performance parameter of the ECU is outside the threshold range corresponding to that performance parameter, which can be the operating voltage. In this case, it is determined whether the current timing time has reached the preset minimum interval time. If the current timing time has reached the preset minimum interval time, an enable signal is triggered to the ECU so that the ECU sends the first data array. If the current timing time has not reached the preset minimum interval time, the current timing time is summed with the preset step time to accumulate the step time and obtain the updated current timing time. Then it is determined whether the current timing time meets the preset minimum interval time. The accumulation of the step time is stopped when the preset minimum interval time is met, and the message data is sent, thereby realizing that the message data is sent at the minimum time interval.

[0041] It should be noted that the above-mentioned cyclic execution steps also include a first judgment step and a third judgment step. The first judgment step includes: judging whether the ECU meets any one of the multiple immediate transmission conditions; the third judgment step includes: judging whether the condition variable is the first preset parameter. Since the condition variable is set to the first preset parameter, the triggered adjustment command can make the judgment result of the first judgment step indicate no when the first judgment step is repeatedly executed. Therefore, when the judgment result of the first judgment step executed for the first time indicates that the ECU meets any one of the immediate transmission conditions (i.e., the judgment result of the first judgment step indicates yes), the judgment result of the first judgment step executed repeatedly will change. And no matter how many times it is repeated, the judgment result of the first judgment step will always be no. Thus, when the judgment result of the first judgment step is no, the third judgment step can be executed sequentially. At this time, although the judgment result of the first judgment step executed repeatedly is no, this does not mean that the ECU does not meet the immediate transmission condition, but because the adjustment command changed the judgment result. Furthermore, since the condition variable has been set to the first preset parameter when the judgment result of the first judgment step executed for the first time indicates that the ECU meets any one of the immediate transmission conditions, the judgment result of the executed third judgment step is yes. Thus, when the judgment result of the third judgment step is yes, the second judgment step can be executed sequentially.

[0042] In some optional implementations, setting the condition variable to a first preset parameter includes: when the ECU meets a first immediate transmission condition, setting the first condition variable to the first preset parameter, wherein the first condition variable is used to characterize whether the first data array is equal to the second data array sent by the ECU in the previous step; when the condition variable is the first preset parameter, the condition variable characterizes that the first data array is equal to the second data array sent by the ECU in the previous step; when the ECU meets a second immediate transmission condition, setting a second condition variable to the first preset parameter, wherein the second condition variable is used to characterize whether the ECU receives a trigger signal; when the condition variable is the first preset parameter, the condition variable characterizes that the ECU receives a trigger signal; when the ECU meets a third immediate transmission condition, setting a third condition variable to the first preset parameter, wherein the third condition variable is used to characterize whether the target performance parameter of the ECU is outside the threshold range corresponding to the target performance parameter; when the condition variable is the first preset parameter, the condition variable characterizes that the target performance parameter is outside the threshold range corresponding to the target.

[0043] Specifically, setting the first condition variable to 1 indicates that the ECU meets the first immediate transmission condition, meaning the first data array expected to be transmitted by the ECU in the current step is not equal to the second data array transmitted by the ECU in the previous step. Alternatively, setting the second condition variable to 1 indicates that the ECU meets the second immediate transmission condition, meaning the ECU receives trigger signals from sources such as sensors, actuators, controller hardwires, and CAN lines. Setting the third condition variable to 1 indicates that the ECU meets the third transmission condition, meaning at least one performance parameter of the ECU is outside the corresponding threshold range. Similarly, if the first condition variable is set to 0, it indicates that the ECU does not meet the first immediate transmission condition, meaning the first data array expected to be transmitted by the ECU in the current step is equal to the second data array transmitted by the ECU in the previous step; if the second condition variable is set to 0, it indicates that the ECU does not meet the second immediate transmission condition, meaning the ECU has not received trigger signals from sources such as sensors, actuators, controller hardwires, and CAN lines; if the third condition variable is set to 0, it indicates that the ECU does not meet the third transmission condition, meaning the performance parameter of the ECU meets the corresponding threshold range.

[0044] In some optional implementations, triggering an adjustment command when the condition variable is set to a first preset parameter includes: when the ECU meets a first immediate transmission condition and the condition variable is set to the first preset parameter, assigning a first data array to a second data array to trigger the adjustment command; when the ECU meets a second immediate transmission condition and the condition variable is set to the first preset parameter, adjusting the ECU's receiving state to no trigger signal received to trigger the adjustment command; and when the ECU meets a third immediate transmission condition and the condition variable is set to the first preset parameter, adjusting the threshold range corresponding to the target performance parameter so that the target performance parameter is within the adjusted threshold range to trigger the adjustment command.

[0045] Specifically, when the condition variable is the first preset parameter (e.g., the first condition variable is set to 1), and the ECU meets the first immediate transmission condition (i.e., the first data array is not equal to the second data array sent by the ECU in the previous step), the current ECU-sent data array is assigned to the data array sent by the ECU in the previous step. This allows the third judgment step to be executed by changing the judgment result of the first judgment step when the second judgment step is not met, avoiding repeated execution of the step of setting the condition variable to the first preset parameter. Similarly, when the condition variable is the first preset parameter, and the ECU meets the second immediate transmission condition (i.e., the ECU receives a trigger signal), the ECU's received... The receiving state is adjusted to no trigger signal received, so that when the second judgment step is not met, the judgment result of the first judgment step can be changed to execute the third judgment step, avoiding repeated execution of the step of setting the condition variable to the first preset parameter; when the condition variable is the first preset parameter, and the ECU meets the third immediate transmission condition, that is, when a certain performance parameter of the ECU is outside the corresponding threshold range, the threshold range corresponding to the performance parameter is adjusted so that the performance parameter is within the adjusted threshold range, which also allows the third judgment step to be executed when the second judgment step is not met, avoiding repeated execution of the step of setting the condition variable to the first preset parameter.

[0046] In some optional implementations, the above-described message data processing method of this application embodiment further includes: if the target immediate transmission condition is not met at the ECU end, a third judgment step is performed: judging whether the condition variable is a first preset parameter; if the condition variable is the first preset parameter, the second judgment step is performed again to obtain a first judgment result; if the first judgment result indicates that the current timing time has not reached the preset minimum interval time, the summation step, the first judgment step, the third judgment step, and the second judgment step are sequentially cyclically repeated at least once until the current timing time reaches the preset minimum interval time.

[0047] Specifically, when the judgment result of the third judgment step indicates that the condition variable is the first preset parameter (e.g., the condition variable is set to 1), the second judgment step is executed to determine whether the current timing time has reached the preset minimum interval time. If the current timing time has reached the preset minimum interval time, an enable signal is triggered to the ECU so that the ECU sends the first data array. If the current timing time has not reached the preset minimum interval time, the current timing time is summed with the preset step time to accumulate the step time and obtain the updated current timing time. Then, it is determined whether the current timing time meets the preset minimum interval time. The accumulation of the step time is stopped when the preset minimum interval time is met, and the message data is sent, thereby realizing that the message data is sent at the minimum time interval.

[0048] In some optional implementations, the above-described message data processing method of this application embodiment further includes: the message data processing method further includes: when the condition variable is not the first preset parameter, performing a fourth judgment step: judging whether the current timing time has reached the preset message sending period, wherein the preset message sending period is greater than the preset minimum interval time; when the current timing time has reached the preset message sending period, triggering an enable signal to the ECU to make the ECU send the first data array; when the current timing time has not reached the preset message sending period, sequentially executing the summation step, the first judgment step, the third judgment step and the fourth judgment step at least once, until the current timing time reaches the preset message sending period and stops.

[0049] If the result of the first judgment step is negative, and the result of the third judgment step is also negative, it means that the ECU does not meet the immediate transmission condition and the condition variable is not the first preset parameter. In this case, the message data needs to be sent at the minimum interval. Instead, the fourth judgment step is used to determine whether the current timing time has reached the preset message transmission period. If the current timing time has reached the preset message transmission period, an enable signal is triggered to the ECU so that the ECU can send the first data array. If the current timing time has not reached the preset message transmission period, the current timing time is summed with the preset step time to accumulate the step time and obtain the updated current timing time. Then, it is determined whether the current timing time meets the preset message transmission period. The accumulation of the step time is stopped when the preset message transmission period is met, and the message data is sent, thereby realizing that the message data is sent at the preset message transmission period.

[0050] For example, when the above condition variable is set to 0, it is determined whether the current timing time has reached the message transmission cycle. The above message transmission cycle can be a cycle in which the ECU usually sends message data. In this embodiment, by setting a preset minimum interval time that is less than the preset message transmission cycle, and by enabling the ECU to send message data when the ECU meets the immediate transmission condition, the CAN bus load rate is effectively reduced, real-time performance is improved, and software maintenance costs are reduced.

[0051] In some optional implementations, the above-described message data processing method of this application embodiment further includes: before the first judgment step is executed for the first time, or when an enable signal is triggered, initializing the condition variable so that the condition variable is set to a second preset parameter, wherein when the condition variable is the second preset parameter, the condition variable indicates that the ECU does not meet the target immediate transmission condition; and when an enable signal is triggered, resetting the current timer to zero.

[0052] For example, before the first judgment step is executed for the first time, or when the enable signal is triggered, the condition variable is set to 0. At this time, the condition variable indicates that the target immediate transmission condition is not met. At the same time, when the enable signal is triggered, the timer is cleared to zero, thus completing the transmission of a message data array.

[0053] The above-described message data processing method in the embodiments of this application will be further described below with reference to specific examples.

[0054] For example, Figure 3 The diagram illustrates the processing flow of a message data processing method, such as... Figure 3 As shown, the processing flow includes the following steps:

[0055] If the first data array expected to be sent by the ECU at the current step size is obtained, the first judgment step is executed: determine whether the data array currently sent by the ECU is equal to the data array sent at the previous step size;

[0056] If the result of the first judgment step is negative, that is, if the data array currently sent by the ECU is not equal to the data array sent in the previous long step, the first condition variable is set to 1 and the data array currently sent by the ECU is assigned to the data array sent in the previous long step, and then the second judgment step is performed: determine whether the current timing time meets the preset minimum interval time.

[0057] If the result of the second judgment step is yes, that is, if the timing time meets the preset minimum interval time, the enable signal will be sent to the ECU, the ECU will send data, and the first data array change satisfaction flag will be set to 0, and the timing time will be cleared to zero.

[0058] If the result of the second judgment step is negative, that is, if the timing time is less than the preset minimum interval time, then the current timing time is superimposed with the step time to obtain the updated timing time, and the process returns to the first judgment step: judging whether the data array currently sent by the ECU is equal to the data array sent by the previous step time, until the result of the second judgment step is positive, that is, when the current timing time meets the preset minimum interval time, an enable signal is sent to the ECU, the ECU sends data, and sets the flag of the first data array change to 0, and the timing time is cleared to zero;

[0059] Since the first condition variable has been set to 1 and the data array currently sent by the ECU has been assigned to the data array sent in the previous long step in the above judgment steps, the result of the first judgment step of the current first data array is yes, that is, the data array currently sent by the ECU is equal to the data array sent in the previous long step, and the result of the third judgment step is yes, that is, when the first condition variable is set to 1, the second judgment step is performed: to determine whether the current timing time meets the preset minimum interval time.

[0060] When the result of the second judgment step is yes, that is, when the timing time meets the preset minimum interval time, the enable signal is sent to the ECU, the ECU sends data, and sets the flag of the first data array change to 0, and the timing time is cleared to zero.

[0061] If the result of the second judgment step is negative, that is, the timing time is less than the preset minimum interval time, the current timing time is superimposed with the step time to obtain the updated timing time, and the process returns to the first judgment step: judging whether the data array currently sent by the ECU is equal to the data array sent by the previous step time, until the result of the second judgment step is positive, that is, the current timing time meets the preset minimum interval time, the enable signal is sent to the ECU, the ECU sends data, and sets the first data array change satisfaction flag to 0, and the timing time is cleared to zero;

[0062] If the result of the first judgment step is yes, that is, the data array currently sent by the ECU is equal to the data array sent in the previous step, and the result of the third judgment step is no, that is, the first condition variable is set to 0, then the fourth judgment step is performed: determine whether the current timing time meets the preset message sending cycle.

[0063] When the result of the fourth judgment step is yes, that is, when the current timing time meets the preset message sending cycle, the enable signal will be sent to the ECU, the ECU will send data, and set the first data array change satisfaction flag to 0, and the timing time will be cleared to zero.

[0064] If the result of the fourth judgment step is negative, that is, the current timing time is less than the preset message sending period, the current timing time is added to the step time to obtain the updated timing time, and the process returns to the first judgment step: judging whether the data array currently sent by the ECU is equal to the data array sent by the previous step time, until the result of the fourth judgment step is positive, that is, the current timing time meets the preset message sending period, then the enable signal is sent to the ECU, the ECU sends data, and sets the first data array change satisfaction flag to 0, and the timing time is cleared to zero, thus completing the transmission of one message data array.

[0065] For example, Figure 4 The diagram illustrates the processing flow of a message data processing method, such as... Figure 4 As shown, the processing flow includes the following steps:

[0066] If the first data array that the ECU is expected to send at the current step size is obtained, the first judgment step is executed: determine whether the ECU has received a trigger signal;

[0067] If the result of the first judgment step is yes, that is, if the ECU receives the trigger signal, the second condition variable is set to 1 and the receiving state of the ECU is adjusted to no trigger signal is received, and then the second judgment step is performed: determine whether the current timing time meets the preset minimum interval time.

[0068] If the result of the second judgment step is yes, that is, if the timing time meets the preset minimum interval time, the enable signal will be sent to the ECU, the ECU will send data, and the first data array change satisfaction flag will be set to 0, and the timing time will be cleared to zero.

[0069] If the result of the second judgment step is negative, that is, if the timing time is less than the preset minimum interval time, then the current timing time is superimposed with the step time to obtain the updated timing time, and the process returns to the first judgment step: to determine whether the ECU has received a trigger signal. Until the result of the second judgment step is positive, that is, if the current timing time meets the preset minimum interval time, then the enable signal is sent to the ECU, the ECU sends data, and sets the flag of the first data array change to 0, and the timing time is cleared to zero.

[0070] Since the second condition variable has been set to 1 and the receiving state of the ECU has been adjusted to not receiving the trigger signal in the above judgment steps, the result of the first judgment step of the first data array is no, that is, the ECU has not received the trigger signal, and the result of the third judgment step is yes, that is, when the second condition variable is set to 1, the second judgment step is performed: to determine whether the current timing time meets the preset minimum interval time.

[0071] When the result of the second judgment step is yes, that is, when the timing time meets the preset minimum interval time, the enable signal is sent to the ECU, the ECU sends data, and sets the flag of the first data array change to 0, and the timing time is cleared to zero.

[0072] If the result of the second judgment step is negative, that is, the timing time is less than the preset minimum interval time, the current timing time is superimposed with the step time to obtain the updated timing time, and the process returns to the first judgment step: whether the ECU has received a trigger signal. Until the result of the second judgment step is positive, that is, the current timing time meets the preset minimum interval time, the enable signal is sent to the ECU, the ECU sends data, and sets the flag of the first data array change to 0, and the timing time is cleared to zero.

[0073] If the result of the first judgment step is negative (i.e., the ECU does not receive a trigger signal) and the result of the third judgment step is negative (i.e., the second condition variable is set to 0), then the fourth judgment step is performed: determine whether the current timing time meets the preset message sending cycle.

[0074] When the result of the fourth judgment step is yes, that is, when the current timing time meets the preset message sending cycle, the enable signal will be sent to the ECU, the ECU will send data, and set the first data array change satisfaction flag to 0, and the timing time will be cleared to zero.

[0075] If the result of the fourth judgment step is negative, that is, the current timing time is less than the preset message sending period, the current timing time is added to the step time to obtain the updated timing time, and the process returns to the first judgment step: judging whether the ECU has received a trigger signal. This continues until the result of the fourth judgment step is positive, that is, the current timing time meets the preset message sending period. At this point, an enable signal is sent to the ECU, the ECU sends data, sets the flag indicating that the first data array has changed to 0, and clears the timing time. This completes the transmission of one message data array.

[0076] For example, Figure 5 The diagram illustrates the processing flow of a message data processing method, such as... Figure 5 As shown, the processing flow includes the following steps:

[0077] If the first data array expected to be sent by the ECU at the current step size is obtained, the first judgment step is executed: determine whether the target performance parameter of the ECU is outside the threshold range corresponding to the target performance parameter;

[0078] If the result of the first judgment step is yes, that is, if the target performance parameter of the ECU is outside the threshold range corresponding to the target performance parameter, the third condition variable is set to 1 and the threshold range is adjusted so that the target performance parameter is within the adjusted threshold range, and then the second judgment step is performed: determine whether the current timing time meets the preset minimum interval time.

[0079] If the result of the second judgment step is yes, that is, if the timing time meets the preset minimum interval time, the enable signal will be sent to the ECU, the ECU will send data, and the first data array change satisfaction flag will be set to 0, and the timing time will be cleared to zero.

[0080] If the result of the second judgment step is negative, that is, if the timing time is less than the preset minimum interval time, then the current timing time is superimposed with the step time to obtain the updated timing time, and the process returns to the first judgment step: judging whether the target performance parameter of the ECU is outside the threshold range corresponding to the target performance parameter, until the result of the second judgment step is positive, that is, when the current timing time meets the preset minimum interval time, an enable signal is sent to the ECU, the ECU sends data, and sets the first data array change satisfaction flag to 0, and the timing time is cleared to zero;

[0081] Since the third condition variable has been set to 1 and the threshold range has been adjusted in the above judgment steps so that the target performance parameter is within the adjusted threshold range, the result of the first judgment step of the current first data array is no, that is, the target performance parameter of the ECU is not outside the threshold range corresponding to the target performance parameter, and the result of the third judgment step is yes, that is, when the third condition variable is set to 1, the second judgment step is performed: judge whether the current timing time meets the preset minimum interval time.

[0082] When the result of the second judgment step is yes, that is, when the timing time meets the preset minimum interval time, the enable signal is sent to the ECU, the ECU sends data, and sets the flag of the first data array change to 0, and the timing time is cleared to zero.

[0083] If the result of the second judgment step is negative, that is, the timing time is less than the preset minimum interval time, the current timing time is superimposed with the step time to obtain the updated timing time, and the process returns to the first judgment step: judging whether the target performance parameter of the ECU is outside the threshold range corresponding to the target performance parameter, until the result of the second judgment step is positive, that is, the current timing time meets the preset minimum interval time, the enable signal is sent to the ECU, the ECU sends data, and sets the first data array change satisfaction flag to 0, and the timing time is cleared to zero;

[0084] If the result of the first judgment step is negative, that is, the target performance parameter of the ECU is not outside the threshold range corresponding to the target performance parameter, and the result of the third judgment step is negative, that is, the third condition variable is set to 0, then the fourth judgment step is performed: determine whether the current timing time meets the preset message sending cycle.

[0085] When the result of the fourth judgment step is yes, that is, when the current timing time meets the preset message sending cycle, the enable signal will be sent to the ECU, the ECU will send data, and set the first data array change satisfaction flag to 0, and the timing time will be cleared to zero.

[0086] If the result of the fourth judgment step is negative, i.e., the current timing time is less than the preset message sending cycle, the current timing time is superimposed with the step time to obtain the updated timing time, and the process returns to the first judgment step: judging whether the target performance parameter of the ECU is outside the threshold range corresponding to the target performance parameter, until the result of the fourth judgment step is positive, i.e., the current timing time meets the preset message sending cycle, then the enable signal is sent to the ECU, the ECU sends data, and sets the flag of the first data array change to 0, and the timing time is cleared to zero, thus completing the transmission of one message data array.

[0087] This application also provides a message data processing apparatus. It should be noted that the message data processing apparatus of this application can be used to execute the message data processing method provided in this application. This apparatus is used to implement the above embodiments and preferred embodiments; details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that performs a predetermined function. Although the apparatus described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0088] To enable those skilled in the art to better understand the technical solution of this application, the message data processing apparatus of this application will be described in detail below with reference to specific embodiments.

[0089] Figure 6 This is a schematic diagram of a message data processing apparatus according to an embodiment of this application. Figure 6 As shown, the device includes:

[0090] The first judgment module 10 is used to perform a first judgment step when the first data array expected to be sent by the ECU in the current step size is obtained: judging whether the ECU meets any one of a plurality of immediate sending conditions, wherein the plurality of immediate sending conditions include a first immediate sending condition, a second immediate sending condition and a third immediate sending condition, the first immediate sending condition is that the first data array is not equal to the second data array sent by the ECU in the previous step size, the second immediate sending condition is that the ECU receives a trigger signal, and the third immediate sending condition is that at least one performance parameter of the ECU is outside the threshold range corresponding to the at least one performance parameter;

[0091] Specifically, the aforementioned first data array serves as input parameters, including calibration value 1, calibration value 2, and calibration value 3. Calibration value 1 is used to calibrate the message period, calibration value 2 is used to calibrate the minimum interval time, and calibration value 3 is used to calibrate different immediate transmission conditions. Specifically, value 1 can be set to represent the immediate transmission condition being a change in the data array transmitted by the ECU with preceding and following steps; value 2 can be set to represent receiving a trigger signal from any of the following: a sensor, actuator, controller hardwire, or CAN line; and value 3 can be set to represent a certain performance parameter of the ECU exceeding or falling below a certain threshold range. By using calibration value 3 to indicate the immediate transmission condition, the function of selecting message data processing under different conditions is realized.

[0092] The second judgment module 20 is used to execute the second judgment step when any one of the immediate transmission conditions is met at the ECU end: to determine whether the current timing time has reached the preset minimum interval time, wherein the starting timing time of the current timing time is the time when the first data array is acquired;

[0093] Specifically, if the current timing time has not reached the preset minimum interval time, the time step is increased by at least one step time based on the current timing time until the updated current timing time reaches the preset minimum interval time, and then the message data is sent, thereby enabling the message to be sent according to the minimum interval time.

[0094] The first trigger module 30 is used to trigger an enable signal to the ECU when the current timing time reaches the preset minimum interval time, so that the ECU sends the first data array.

[0095] Specifically, when the current timing reaches the preset minimum interval, the ECU is enabled to send message data, thereby enabling the message data to be sent at the minimum time interval.

[0096] In the apparatus described in this application embodiment, when the first judgment module 10 obtains the first data array currently being sent by the ECU, it determines whether the ECU meets any one of a plurality of immediate transmission conditions. If any one of the immediate transmission conditions is met, the second judgment step is then executed. By setting different immediate transmission conditions, the transmission of message data under different immediate transmission conditions can be achieved. Then, the second judgment module 20 determines whether the current timing time has reached the preset minimum interval time. Under the required immediate transmission conditions, the first trigger module 30 enables the ECU to send message data according to the minimum interval time. Since the above message data processing method in this application can send the most recent message according to the minimum interval time when the immediate transmission condition, such as the change in the message data sent by the ECU before and after the step size, is met, the CAN bus load rate is effectively reduced, real-time performance is improved, and software maintenance costs are reduced.

When the first preset parameter is true, an adjustment instruction is triggered. When the first judgment step is repeatedly executed, the adjustment instruction is used to make the judgment result of the first judgment step indicate no. The first loop module is used to sequentially execute the summation step, the first judgment step, the third judgment step, and the second judgment step at least once when the judgment result of the first judgment step indicates yes and the judgment result of the second judgment step indicates no, until the current time reaches the preset minimum interval time. The summation step includes: summing the current time with the preset step time to obtain the updated current time. The third judgment step includes: judging whether the condition variable is the first preset parameter.

[0099] In some optional implementations, when the condition variable is set to a first preset parameter, the second triggering module includes: a first triggering submodule, configured to assign a first data array to a second data array to trigger an adjustment command when the first immediate transmission condition is met at the ECU and the condition variable is set to the first preset parameter; a second triggering submodule, configured to adjust the receiving state of the ECU to no trigger signal received when the second immediate transmission condition is met at the ECU and the condition variable is set to the first preset parameter; and a third triggering submodule, configured to adjust the threshold range corresponding to the target performance parameter so that the target performance parameter is within the adjusted threshold range when the third immediate transmission condition is met at the ECU and the condition variable is set to the first preset parameter.

[0101] In some optional implementations, the above-described message data processing method of the application embodiment further includes: a fifth judgment module, used to execute a fourth judgment step when the condition variable is not a first preset parameter: judging whether the current timing time has reached a preset message sending period, wherein the preset message sending period is greater than a preset minimum interval time; when the current timing time has reached the preset message sending period, triggering an enable signal to the ECU to make the ECU send a first data array; and a third loop module, used to sequentially execute the summation step, the first judgment step, the third judgment step, and the fourth judgment step at least once when the current timing time has not reached the preset message sending period, until the current timing time reaches the preset message sending period.

The first immediate sending condition is that the first data array is not equal to the second data array sent by the ECU at the previous step length. The second immediate sending condition is that the ECU receives a trigger signal. The third immediate sending condition is that at least one performance parameter of the ECU is outside the threshold range corresponding to the at least one performance parameter.

By using calibration value 3 to indicate the immediate transmission condition, the function of selecting message data processing under different conditions is realized.

[0113] Step S204: If any one of the immediate transmission conditions is met at the ECU end, execute the second judgment step: determine whether the current timing time has reached the preset minimum interval time, wherein the starting timing time of the current timing time is the time when the first data array is acquired;

[0114] Specifically, if the current timing time has not reached the preset minimum interval time, the time step is increased by at least one step time based on the current timing time until the updated current timing time reaches the preset minimum interval time, and then the message data is sent, thereby enabling the message to be sent according to the minimum interval time.

[0115] Step S206: When the current timing time reaches the preset minimum interval time, trigger an enable signal to the ECU so that the ECU sends the first data array.
