Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a response delay configuration method based on a communication bus and related devices. Background Art

[0002] Response latency refers to the waiting time between a master device receiving a request signal from a slave device and sending a response signal. The configuration of this response latency can affect the reliability and stability of data transmission. In in-vehicle communications, the host typically uses a fixed response latency to handle read and write operations from slave devices connected to the communication bus. However, the internal environment of a vehicle during operation is complex, and the signal transmission speed and processing speed of different slave devices can fluctuate due to environmental influences, resulting in the host's response latency being too long or too short. Excessively long response latency can cause the host to wait unnecessarily, wasting hardware resources. Excessively short response latency can lead to data transmission failures and communication timeouts.

[0003] Currently, solutions to the problem of host-side response delays being too long or too short due to environmental influences include introducing long-term bus occupancy during transmission to avoid response timeouts, introducing communication bus recovery mechanisms at the hardware level, and introducing slave device responses in the bus idle state to improve communication bus response stability. However, these solutions require either modifying the standard communication bus protocol, introducing additional hardware, or adding new bus states, all of which complicate the communication bus hardware or protocol.

[0004] In summary, the existing technology cannot simply and effectively solve the problem of the host-side response delay being too long or too short due to environmental influences. Summary of the Invention

[0075] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0076] Exemplary embodiments are described in detail herein, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with certain aspects of the present application.

[0077] First, the terms involved in this application are explained.

[0078] Response delay: refers to the waiting time from receiving a request signal to sending a response signal.

[0079] Response time: refers to the waiting time from sending a request message to receiving a response signal.

[0080] Data transmission accuracy: refers to the proportion of data accurately transmitted from the sender to the receiver within the monitoring period.

[0081] Data transmission error rate: refers to the ratio of the data received by the receiving end to the data sent by the sending end due to various reasons during the monitoring period.

[0082] Average data length: refers to the average number of data bits contained in each transmission during the monitoring period.

[0083] Average response time of slave devices: refers to the average waiting time from when the master device sends a request message to when it receives a response signal from the slave device during the monitoring period.

[0084] Communication bus voltage value: refers to the voltage value of the communication bus connected between the master device and the slave device.

[0085] Ambient temperature of the slave device: refers to the temperature of the slave device's working environment.

[0086] First, the prior art involved in this application is described in detail.

[0087] In in-vehicle communications, the host typically uses a fixed response delay to process read and write operations from slave devices connected to the communication bus. This means that after receiving a request signal from a slave, the master waits for a fixed response delay before sending a response signal to the slave. However, the internal environment of a vehicle is complex, and signal transmission speeds and the processing speeds of different slave devices can fluctuate due to environmental influences. For example, changes in the ambient temperature of a slave device can affect its operating state, leading to fluctuations in signal transmission speed, processing speed, or data stability between the master and slave. In such situations, if the master still uses a fixed response delay, the host's response delay may be too long or too short. Excessively long response delays cause unnecessary waiting on the host side, wasting hardware resources, while too short response delays can lead to data transmission failures and communication timeouts. In in-vehicle communication applications, unnecessary waiting on the host side, data transmission failures, and communication timeouts can affect the responsiveness of the in-vehicle system and may even pose a potential threat to vehicle safety.

[0088] In the prior art, there are three main solutions to the problem of host-side response delays being too long or too short due to environmental influences. The first is to introduce a method of long-term bus occupation during the transmission process to avoid response timeouts. The second is to introduce a communication bus recovery mechanism at the hardware level. The third is to introduce a slave device bus idle state response. However, the first and third solutions require modifications to the communication bus protocol, and the second solution requires the introduction of additional hardware, which complicates the hardware or protocol of the communication bus, and neither is suitable for in-vehicle communication.

[0089] In summary, the existing technology cannot simply and effectively solve the problem of the host-side response delay being too long or too short due to environmental influences.

[0090] In response to the above problems in the prior art, the present application proposes the following inventive concept: a fixed response delay cannot adapt to the complex environmental changes in vehicle-mounted communication application scenarios. Therefore, if the response delay of the master device to the slave device can match the communication status between the master device and the slave device, then the problem of the master device's response delay being too long or too short can be avoided without adding hardware or modifying the communication protocol. Therefore, by monitoring the communication status between the master device and the slave device, it is possible to determine whether the master device's response delay to the slave device needs to be adjusted, and determine the target response delay based on the communication status-related data of the current monitoring cycle between the master device and the slave device. The target response delay is the response delay that matches the current communication status between the master device and the slave device, which can avoid the master device's response delay to the slave device being too long or too short, thereby simply and effectively solving the problem of the host side's response delay being too long or too short due to environmental influences.

[0091] Figure 1 Schematic diagram of an application scenario of the communication bus-based response delay configuration method provided in an embodiment of the present application, such as Figure 1 As shown, in an application scenario of the communication bus-based response delay configuration method provided in an embodiment of the present application, the method includes: a master device 11 and at least one slave device 12, and the master device 11 and the slave device 12 are connected via a communication bus 13. The master device 11 includes a processor.

[0092] The processor of the master device 11 obtains data related to the communication status of the current monitoring cycle between the master device 11 and the slave device 12.

[0093] The processor of the master device 11 determines the target response delay of the master device 11 to the slave device 12 based on the communication status related data of the current monitoring cycle between the master device 11 and the slave device 12; the target response delay is the response delay that matches the current communication status between the master device 11 and the slave device 12.

[0094] The processor of the master device 11 adjusts the response delay of the master device 11 to the slave device 12 to the target response delay.

[0095] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0096] The execution subject of the response delay configuration method based on the communication bus provided in the embodiment of the present application is a response delay configuration device, which is located in a processor, the processor is located in a master device, the master device is located in a preset network architecture, and the preset network architecture also includes at least one slave device, and the slave device is connected to the master device through a communication bus.

[0097] Figure 2 Schematic diagram of the process of configuring the response delay based on the communication bus provided in the embodiment of the present application Figure 1 .like Figure 2 As shown, the communication bus-based response delay configuration method provided in the embodiment of the present application includes S201 to S203.

[0098] S201, obtaining data related to the communication status of the current monitoring cycle between the master device and the slave device.

[0099] In this embodiment, a master device may refer to the device that performs the primary tasks in a communication or control system, and a slave device may refer to the device that is primarily controlled by the master device in the communication or control system. The master device may be responsible for coordinating and dividing tasks across the entire system, while the slave device may be responsible for executing specific tasks and responding to instructions from the master device. The master device exchanges data with the slave device via a communication bus, for example, sending control instructions and receiving status feedback.

[0100] In some application scenarios, the master device may also be responsible for managing the human-computer interaction interface, such as receiving user input and displaying information such as system status.

[0101] For example, in an in-vehicle communication scenario, for example, in a smart cockpit system, the master device may be a system-on-chip including a main control processor, and the slave devices may include a central control screen, an LCD instrument, and a head-up display HUD, etc.

[0102] In this embodiment, the processor may obtain data related to the communication status between the master device and the slave device according to a set monitoring period, and further obtain data related to the communication status of the current monitoring period.

[0103] Optionally, the communication status related data includes: at least one of communication quality information or communication environment information.

[0104] The communication quality information includes at least one of the following indicators: data transmission accuracy, data transmission error rate, average data length, and average response time of the slave device.

[0105] The communication environment information includes at least one of the following indicators: a voltage value of the communication bus and an ambient temperature of the slave device.

[0106] Among them, data transmission accuracy, data transmission error rate, average data length, and average response time of the slave device are indicators used to measure the communication quality between the master device and the slave device.

[0107] The data transmission accuracy rate is the probability that data transmitted between the master and slave devices is accurate within a monitoring cycle. The data transmission error rate is the probability that errors occur in data transmitted between the master and slave devices within a monitoring cycle. The average data length is the average number of bits in data transmitted between the master and slave devices within a monitoring cycle. The average slave response time is the average waiting time between the master sending a request and receiving a response from the slave within a monitoring cycle.

[0108] The voltage value of the communication bus and the ambient temperature of the slave device are indicators used to measure the communication environment between the master device and the slave device.

[0109] The voltage value of the communication bus refers to the voltage value of the communication bus connected between the master device and the slave device. The ambient temperature of the slave device refers to the temperature value of the working environment of the slave device.

[0110] S202, determining a target response delay of the master device to the slave device based on data related to the communication status of the current monitoring cycle between the master device and the slave device; the target response delay is a response delay that matches the current communication status between the master device and the slave device.

[0111] In this embodiment, the communication status related data may include at least one of the following indicators: data transmission accuracy, data transmission error rate, average data length, average response time of the slave device, voltage value of the communication bus, and ambient temperature of the slave device.

[0112] In this embodiment, a memory communicatively connected to the processor may store multiple first mapping relationships, each of which may be a mapping relationship between a preset communication state-related data set and a preferred response delay. The processor may retrieve the multiple first mapping relationships from the memory; determine the target communication state-related data set to which the communication state-related data of the current monitoring period belongs from the multiple first mapping relationships; and determine the target response delay as the preferred response delay associated with the target communication state-related data set.

[0113] Exemplarily, when the communication status related data includes the average data length and the ambient temperature of the slave device, the preset communication status related data set may include: communication status related data with the average data length ranging from a first length to a second length and the ambient temperature of the slave device ranging from a first temperature to a second temperature.

[0114] S203: Adjust the response delay of the master device to the slave device to the target response delay.

[0115] In this embodiment, the processor adjusts the response delay of the master device to the slave device to the target response delay, so that the response delay of the master device to the slave device can match the current communication status between the master device and the slave device, thereby avoiding the response delay of the master device to the slave device being too long or too short.

[0116] The communication bus-based response delay configuration method provided in this embodiment obtains data related to the communication status of the current monitoring cycle between the master device and the slave device; the communication status data of the current monitoring cycle can reflect the communication status between the master device and the slave device, and then, based on the communication status data of the current monitoring cycle between the master device and the slave device, determines the target response delay of the master device to the slave device; the target response delay is the response delay that matches the current communication status between the master device and the slave device; therefore, the response delay that matches the current communication status between the master device and the slave device can be accurately determined, and then the response delay of the master device to the slave device is adjusted to the target response delay, which can achieve the effect of simply and effectively solving the problem of the host-side response delay being too long or too short due to environmental influences.

[0117] Figure 3 Schematic diagram of the process of configuring the response delay based on the communication bus provided in the embodiment of the present application Figure 2 .like Figure 3 As shown, the communication bus-based response delay configuration method provided in the embodiment of the present application further includes S301 to S302 before S202.

[0118] S301, obtaining data related to the communication status between the master device and the slave device during a historical monitoring period.

[0119] In this embodiment, the communication status related data of the historical monitoring period may be the communication status related data of the previous monitoring period.

[0120] S302 : Determine whether a response delay of the master device to the slave device needs to be adjusted based on data related to the communication status of the master device and the slave device in historical monitoring cycles and a current monitoring cycle.

[0121] In this embodiment, the fluctuation of each indicator from the previous monitoring period to the current monitoring period can be calculated based on the values ​​of each indicator in the communication status-related data of the previous monitoring period and the values ​​of each indicator in the communication status-related data of the current monitoring period. Based on the fluctuation value of each indicator and the corresponding fluctuation threshold, it is determined whether the response delay of the master device to the slave device needs to be adjusted.

[0122] In this embodiment, the fluctuation value can be an increasing value, a decreasing value, or 0. The fluctuation threshold corresponding to each indicator can be different. The fluctuation threshold can include an increasing threshold or a decreasing threshold, and the increasing threshold and the decreasing threshold can be unequal or equal.

[0123] For example, if the data transmission error rate in the communication status data of a historical monitoring period is a, and the data transmission error rate in the communication status data of a current monitoring period is b, then the fluctuation value of the data transmission error rate from the historical monitoring period to the current monitoring period is ba. If a>b, the fluctuation value of the data transmission error rate is a decreasing value; if b>a, the fluctuation value of the data transmission error rate is an increasing value; if a=b, the fluctuation value of the data transmission error rate is 0.

[0124] In this embodiment, the fluctuation threshold corresponding to each indicator can be pre-stored in a memory that is communicatively connected to the processor. The processor can read the fluctuation threshold corresponding to each indicator from the memory, and then determine whether the response delay of the master device to the slave device needs to be adjusted based on the fluctuation value of each indicator.

[0125] As an optional implementation, when the communication status related data includes only one of the above indicators, it can be determined that the response delay of the master device to the slave device needs to be adjusted when the fluctuation value of the indicator is greater than or equal to the corresponding fluctuation threshold.

[0126] As an optional implementation, when the communication status-related data includes multiple indicators among the above-mentioned indicators, the indicators with fluctuation values ​​greater than or equal to the corresponding fluctuation thresholds can be determined as fluctuation items, and the response delay of the master device to the slave device can be determined to need to be adjusted based on the number of fluctuation items. Exemplarily, it can be determined whether the response delay of the master device to the slave device needs to be adjusted when the number of fluctuation items is greater than or equal to the fluctuation item threshold. For example, when the communication status-related data includes at least 3 of the above-mentioned indicators and the fluctuation item threshold is 3, if only two of the multiple indicators included in the communication status-related data are determined to be fluctuation items, it can be determined that the response delay of the master device to the slave device does not need to be adjusted; if 3 of the multiple indicators included in the communication status-related data are determined to be fluctuation items, it can be determined that the response delay of the master device to the slave device needs to be adjusted.

[0127] The communication bus-based response delay configuration method provided in this embodiment can accurately determine whether the communication status between the master device and the slave device has changed through the communication status-related data and historical status-related data of the current monitoring cycle between the master device and the slave device, and further determine whether the response delay of the master device to the slave device needs to be adjusted.

[0128] Optionally, in the embodiment of the present application, S302 is refined to include S401.

[0129] S401 , in response to any indicator in the communication status related data, if the fluctuation value from the historical monitoring period to the current monitoring period is greater than the corresponding fluctuation threshold, it is determined that the response delay of the master device to the slave device needs to be adjusted.

[0130] In this embodiment, the communication status-related data includes at least one of communication quality information and communication environment information. The communication quality information includes at least one of the following indicators: data transmission accuracy rate, data transmission error rate, average data length, and average response time of the slave device. The communication environment information includes at least one of the following indicators: the voltage value of the communication bus and the ambient temperature of the slave device. The processor may determine that the response delay of the master device to the slave device needs to be adjusted when the fluctuation value of any of the indicators exceeds the corresponding fluctuation threshold.

[0131] When the fluctuation value of an indicator in the communication quality information exceeds the corresponding fluctuation threshold, it indicates that the communication quality between the master and slave devices has improved or deteriorated. Therefore, the response delay of the master device to the slave device needs to be adjusted. When the fluctuation value of an indicator in the communication environment information exceeds the corresponding fluctuation threshold, it indicates that the communication environment between the master and slave devices has changed. To adapt to the impact of this change on the communication status or communication quality, the response delay of the master device to the slave device also needs to be adjusted.

[0132] For example, if the communication status-related data includes a data transmission error rate and the ambient temperature of the slave device, and the communication status-related data for a historical monitoring period shows a data transmission error rate of 3‰ and a slave device ambient temperature of 25°C, and the communication status-related data for a current monitoring period shows a data transmission error rate of 6‰ and a slave device ambient temperature of 40°C, then the increase in the data transmission error rate is 3‰, and the increase in the slave device ambient temperature is 15°C.

[0133] If the data transmission error rate rising threshold is 5‰ and the slave device's ambient temperature rising threshold is 20°C, since 3‰ < 5‰ and 15°C < 20°C, it can be determined that the master device's response delay to the slave device does not need to be adjusted.

[0134] If the data transmission error rate rising threshold is 2‰, since 3‰>2‰, it can be determined that the response delay of the master device to the slave device needs to be adjusted.

[0135] If the rising threshold of the device's ambient temperature is 10°C, since 15°C > 10°C, it can be determined that the response delay of the master device to the slave device needs to be adjusted.

[0136] It should be understood that the fluctuation value in this embodiment is merely one form of indicating the change in the communication status between the master and slave devices from the previous monitoring period to the current monitoring period. The fluctuation value may also be expressed as a fluctuation ratio. Fluctuation values ​​may include rising and falling values, and fluctuation thresholds may include rising and falling thresholds. Different indicators may correspond to different fluctuation thresholds, and the same indicator may correspond to different rising and falling thresholds.

[0137] The communication bus-based response delay configuration method provided in this embodiment determines that the response delay of the master device to the slave device needs to be adjusted when the fluctuation value of any indicator is greater than the corresponding fluctuation threshold. This can accurately determine whether the response delay of the master device to the slave device needs to be adjusted.

[0138] Optionally, in an embodiment of the present application, the communication status-related data includes at least one of communication quality information and communication environment information; the communication bus includes a serial clock line and a serial data line; the serial clock line is used to achieve clock synchronization between the master device and the slave device, and the serial data line is used for data transmission between the master device and the slave device; the step of "obtaining communication status-related data between the master device and the slave device" is refined to include S501 or S502.

[0139] S501 , determining whether a set monitoring period has been reached based on a clock signal on a serial clock line.

[0140] In this embodiment, the processor includes a controller that controls the serial clock line and serial data line of the communication bus. The serial clock line transmits the clock signal between the master device and the slave device. Therefore, changes in the environment will also affect the clock signal transmitted on the serial clock line. In order to accurately sample data related to the communication status, whether the set monitoring period is reached can be determined based on the clock signal on the serial clock line.

[0141] S502: In response to reaching a set monitoring period, perform at least one of the following:

[0142] Calculate communication quality information based on the data sent and received by the serial data line within a set monitoring period;

[0143] Get the collected communication environment information.

[0144] In this embodiment, since the communication status-related data includes at least one of communication quality information or communication environment information, when a set monitoring period is reached, the processor, corresponding to the communication status-related data including at least one of the communication quality information or communication environment information, performs at least one of the following: calculating the communication quality information based on data transmitted and received by the serial data line during the current monitoring period; or obtaining the collected communication environment information. Consequently, the processor is able to obtain at least one of the communication quality information or communication environment information.

[0145] In this embodiment, the controller in the processor can determine whether the data sent and received each time is correct, the data length of each data sent and received, and the average response time of the slave device each time data is sent and received during the process of controlling the serial data line to send and receive data. Therefore, the processor can calculate the data transmission accuracy, data transmission error rate, average data length and average response time of the slave device based on the data sent and received by the serial data line within a set monitoring period.

[0146] The voltage value of the communication bus can be measured using circuit principles, and the ambient temperature of the slave device can be measured by a temperature sensor installed at the slave device. The temperature sensor can also be a slave device connected to the master device, so the processor can obtain the ambient temperature of the slave device by communicating with the temperature sensor.

[0147] The communication bus-based response delay configuration method provided in this embodiment can accurately sample the signal on the serial data line by determining whether the set monitoring period has been reached based on the clock signal on the serial clock line. When obtaining communication status-related data, it can not affect the response of the master device to the slave device, thereby ensuring smooth data transmission.

[0148] Optionally, in the embodiment of the present application, S204 “adjusting the response delay of the master device to the slave device to the target response delay” is further refined to include S601 to S602.

[0149] S601, determining a controller corresponding to a communication bus having a communication connection relationship with a slave device, where the controller is located in a processor of a master device.

[0150] In this embodiment, since multiple master devices and multiple slave devices can be mounted on a communication bus, and a master device can correspond to multiple slave devices, the processor of the master device is connected to the communication bus via its controller. Therefore, when the processor adjusts the response delay of the master device to the slave device to the target response delay, it needs to first determine the controller corresponding to the communication bus that has a communication connection relationship with the slave device.

[0151] S602: Adjust the response delay parameter stored in the instruction register of the corresponding controller to the target response delay.

[0152] In this embodiment, the response delay of the master device to the slave device is controlled by the controller of the processor. The controller corresponding to the slave device controls the response delay of the master device to the slave device through the response delay parameter stored in its instruction register. Therefore, the processor first determines the controller corresponding to the communication bus connected to the slave device, and then adjusts the response delay parameter stored in the instruction register of the corresponding controller to the target response delay.

[0153] The communication bus-based response delay configuration method provided in this embodiment can quickly and accurately adjust the response delay of the master device to the slave device to the target response delay by adjusting the response delay parameter stored in the instruction register.

[0154] Optionally, in an embodiment of the present application, “determining a target response delay based on communication status related data of a current monitoring period” in S202 is further refined to include S701 to S702.

[0155] S701: Input the communication status related data of the current monitoring cycle between the master device and the slave device into the trained target response delay calculation model, and calculate and output the target response delay using the trained target response delay calculation model.

[0156] In this embodiment, the trained target response delay calculation model may be a convolutional neural network model, a linear fitting function, or the like.

[0157] When the trained target response delay calculation model is a convolutional neural network model, the input to the trained target response delay calculation model is multiple indicators included in the communication status related data of the current monitoring period. The convolutional neural network model processes the multiple indicators, calculates the target response delay and outputs it.

[0158] When the trained target response delay calculation model is a linear fitting function, the linear fitting function may include multiple independent variables, and the input to the linear fitting function is multiple indicators included in the communication status-related data of the current monitoring period. The linear fitting function uses the multiple indicators as independent variables, calculates the value of the dependent variable, and determines the calculated value of the dependent variable as the target response delay.

[0159] The communication bus-based response delay configuration method provided in this embodiment can quickly and accurately calculate the target response delay through a preset target response delay calculation function or a trained target response delay determination model.

[0160] Optionally, in an embodiment of the present application, the trained target response delay calculation model is obtained using methods such as S801 to S803.

[0161] S801, obtaining preferred communication status related data between the master device and the slave device, in which the data transmission error rate is lower than the transmission error rate screening threshold, and the response delay of the master device to the slave device corresponding to the preferred communication status related data.

[0162] In this embodiment, the communication status related data is preferably communication status related data between the master device and the slave device within a monitoring period, and the data transmission error rate is lower than the transmission error rate screening threshold.

[0163] In this embodiment, the communication between the master device and the slave device can be simulated in the laboratory, and the communication status data between the master device and the slave device can be obtained according to the set monitoring period. Furthermore, at least one preferred communication status-related data with a data transmission error rate lower than the transmission error rate screening threshold can be screened out from the communication status data of each monitoring period between the master device and the slave device, and the response delay of the master device to the slave device corresponding to each preferred communication status-related data can be obtained.

[0164] The sum of the data transmission error rate and the data transmission accuracy rate is 1. Therefore, at least one preferred communication status related data having a data transmission accuracy rate higher than the transmission error rate screening threshold can also be obtained.

[0165] It is understandable that the data transmission error rate of the communication status related data may preferably be equal to the transmission error rate screening threshold, or equal to the data transmission accuracy threshold.

[0166] In this embodiment, before selecting and selecting communication status-related data, the acquired communication status data between the master and slave devices may be cleaned and normalized. Data cleansing is used to remove outliers and noise from the communication status data between the master and slave devices. Normalization ensures that all indicators have the same magnitude.

[0167] S802, using each indicator in each preferred communication state related data, perform linear regression fitting on the response delay of the master device to the slave device corresponding to each preferred communication state related data, and obtain a linear regression fitting model between each indicator in each preferred communication state related data and the response delay of the master device to the slave device corresponding to each preferred communication state related data.

[0168] When the communication status related data includes only one indicator, the linear regression fitting is a single-parameter linear regression fitting; when the communication status related data includes multiple indicators, the linear regression fitting is a multi-parameter linear regression fitting. The linear regression fitting can be performed in the processor or in a fitting device connected to the processor. Moreover, the linear regression fitting can be performed before executing the response delay configuration method of the present application or can be performed continuously during the execution of the response delay configuration method of the present application to update the trained target response delay calculation model, which is not limited here.

[0169] S803: Determine the linear regression fitting model as the trained target response delay calculation model.

[0170] The communication bus-based response delay configuration method provided in this embodiment can simply and quickly obtain a trained target response delay calculation model through linear regression fitting.

[0171] As an optional implementation, after obtaining the communication status related data of the current monitoring cycle between the master device and the slave device, the trained target response delay determination model can be continuously trained and updated based on the communication status related data of the current monitoring cycle, the response delay of the master device to the slave device corresponding to the current monitoring cycle, the communication status related data of the historical monitoring cycle, and the response delay of the master device to the slave device corresponding to the historical monitoring cycle, so as to improve the accuracy of the target response delay calculated by the trained target response delay determination model, so that the target response delay can better match the current communication status between the master device and the slave device.

[0172] Optionally, in the embodiment of the present application, after S301 , S901 to S902 are also included.

[0173] S901 , determining whether the working condition between the master device and the slave device has changed based on data related to the communication status between the master device and the slave device in a historical monitoring period and a current monitoring period.

[0174] S902: If it is determined that the working condition between the master device and the slave device has changed, the length of the monitoring period is adjusted according to the current working condition corresponding to the communication status related data of the current monitoring period.

[0175] In this embodiment, the working conditions between the master device and the slave device can be determined based on one or more items of the communication status related data, and further, the working conditions between the master device and the slave device during the previous monitoring cycle and the working conditions between the master device and the slave device during the current monitoring cycle can be determined, and further, it can be determined whether the working conditions between the master device and the slave device have changed from the previous monitoring cycle to the current monitoring cycle.

[0176] When the working conditions between the master device and the slave device change, the duration of the monitoring period for acquiring communication status-related data can be adjusted to the duration matching the current working conditions corresponding to the communication status-related data of the current monitoring period. The duration matching each working condition can be a preset value.

[0177] In this embodiment, since acquiring data related to the communication status between the master and slave devices also consumes processor computing resources, the monitoring frequency can be determined based on the operating conditions between the master and slave devices. For example, in driving conditions, the monitoring frequency can be increased to avoid excessively long or short response delays from the master to the slave devices. In parking conditions, the monitoring frequency can be reduced to conserve processor computing resources.

[0178] The communication bus-based response delay configuration method provided in this embodiment can simply and effectively solve the problem of excessively long or short response delay on the host side due to environmental influences by adjusting the length of the monitoring cycle, while further saving hardware resources.

[0179] Optionally, in any of the above embodiments, the communication bus may be an IIC bus.
