Description

Technical Field

[0001] This invention relates to the field of vehicle control technology, and more specifically, to a control method, control device, storage medium, and program for a vehicle in a ready state. Background Technology

[0002] Currently, in the field of diesel engine vehicle maintenance and inspection, especially during the annual vehicle inspection process, ensuring that vehicles meet the fault monitoring requirements stipulated by regulations is an important aspect.

[0003] However, existing control strategies lack effective mechanisms to track and record key data related to the vehicle's readiness status after error clearing, such as the overall readiness status of the storage module, CVN value, and operating torque value. This means that even if the vehicle is driven after error clearing, it is impossible to accurately determine which monitoring functions have been verified and which are still incomplete. Summary of the Invention

[0004] The main objective of this invention is to provide a method, device, storage medium, and program for controlling the ready state of a vehicle, in order to solve the problem that existing vehicle control strategies cannot track and record the ready state of a vehicle after error clearing.

[0005] To achieve the above objectives, according to one aspect of the present invention, a method for controlling the ready state of a vehicle is provided, comprising: step S1: performing a fault clearing operation on the vehicle to reset the ready state of the vehicle; step S2: starting the vehicle to travel for a preset time t, and recording at least one of the vehicle's ready state, CVN value, and operating torque value within the preset time t; step S3: determining whether the ready state of each group of the vehicle is completed; if the ready state of all groups is completed, then the vehicle is in a ready state; if the ready state of at least one group is not completed, then comparing the consistency between the current CVN value and the historical CVN value, obtaining the historical ready state completion rate of the vehicle's storage module, and obtaining the relationship between the engine operating parameter curve and the standard parameter curve within the preset time t, in a preset order, to determine whether the current operating condition of the vehicle meets the ready condition; wherein, the engine operating parameter curve includes a torque-speed relationship graph and a power-speed relationship graph.

[0006] Furthermore, in step S3, if the current operating condition of the vehicle does not meet the ready operating condition, the vehicle ready state control method further includes: outputting at least one of the speed report, throttle report and gear information of the group that does not meet the ready operating condition to the driver of the vehicle, so as to guide the driver to adjust the current operating condition of the vehicle.

[0007] Furthermore, the method for comparing the consistency between the current CVN value and the historical CVN value, obtaining the historical readiness status completion of the vehicle's storage module, and obtaining the relationship between the engine operating parameter curve of the vehicle and the standard parameter curve within a preset time t, according to a preset order, includes: first comparing the consistency between the current CVN value and the historical CVN value, obtaining the historical readiness status completion of the vehicle's storage module; if the current CVN value and the historical CVN value are consistent and the historical readiness status of the vehicle's storage module is completed, then obtaining the relationship between the engine operating parameter curve of the vehicle and the standard parameter curve within a preset time t.

[0008] Furthermore, the method for determining whether the current operating condition of the vehicle meets the ready condition includes: if the difference between the operating parameter curve of the vehicle's engine and the standard parameter curve is always less than the preset difference within a preset time t, then it is determined that the current operating condition of the vehicle does not meet the ready condition.

[0009] Furthermore, the method of guiding the driver to adjust the current operating conditions of the vehicle includes: presenting at least one of the speed report, throttle report and gear information of the group that does not meet the ready condition to the driver through an interactive interface such as Zhiduoxing or a mobile APP, and guiding the driver to perform the corresponding operation test to complete the ready state.

[0010] Furthermore, the vehicle readiness control method also includes step S01, which precedes step S1: reading the CVN value of the vehicle's control module and comparing it with the historical CVN value stored in the storage module to confirm the consistency of the control module's software version.

[0011] Furthermore, the vehicle readiness control method also includes step S02, which precedes step S01: collecting environmental factors during vehicle operation and determining the degree of influence of environmental factors on the engine's operating parameter curve, so as to adjust the standard parameter curve according to the degree of influence; wherein, environmental factors include at least one of ambient temperature, ambient humidity, and altitude.

[0012] According to another aspect of the present invention, a control device for a vehicle ready state is provided. The control device includes: a memory for storing relevant program code; and a processor for calling the program code and executing the above-described control method for the vehicle ready state.

[0013] According to another aspect of the present invention, a computer-readable storage medium is provided for storing a computer program for executing the above-described vehicle readiness state control method.

[0014] According to another aspect of the present invention, a computer program product is provided, the computer program product comprising a program that, when the program is run on a processor, causes a computer or network device to perform the above-described vehicle ready state control method.

[0015] By applying the technical solution of this invention, a service tool is used to clear faults in the vehicle and reset its ready state. The vehicle is then driven for a preset time t, and key parameters are recorded. This control method can efficiently and accurately detect the vehicle's ready state after fault clearance. In particular, in step S3, the ready state of each group is judged one by one. If the vehicle is not fully ready, by comparing the CVN value, historical ready state, and the relationship between the operating parameter curve and the standard parameter curve, the difference between the vehicle's current operating condition and its ready state can be precisely identified. This improves the accuracy and efficiency of the detection, ensuring that the vehicle reaches its optimal testing readiness state before annual inspection or other compliance tests. This solves the problem in existing technologies where vehicle control strategies cannot track and record the vehicle's ready state after fault clearance. Attached Figure Description

[0022] To address the problem that existing vehicle control strategies cannot track and record the vehicle's ready state after error clearing, this application provides a vehicle ready state control method, control device, storage medium, and program.

[0023] like Figure 1 and Figure 2 As shown, the control method for the vehicle's ready state includes:

[0024] Step S1: Perform a fault clearing operation on the vehicle to reset its ready state;

[0025] Step S2: Start the vehicle and drive for a preset time t, and record at least one of the vehicle's ready status, CVN value and running torque value within the preset time t;

[0026] Step S3: Determine whether the readiness status of each group of the vehicle is complete. If the readiness status of all groups is complete, the vehicle is ready. If the readiness status of at least one group is not complete, compare the consistency between the current CVN value and the historical CVN value in a preset order, obtain the historical readiness status completion rate of the vehicle's storage module, and obtain the relationship between the engine operating parameter curve and the standard parameter curve within a preset time t to determine whether the current operating condition of the vehicle meets the readiness condition. The engine operating parameter curve includes the relationship between torque and speed and the relationship between power and speed.

[0027] By applying the technical solution of this embodiment, a service tool is used to perform fault clearing operations on the vehicle and reset its ready state. The vehicle is then driven for a preset time t, and key parameters are recorded. This control method can efficiently and accurately detect the vehicle's ready state after fault clearing. In particular, in step S3, the ready state of each group is judged one by one. If the vehicle is not fully ready, by comparing the CVN value, historical ready state, and the relationship between the operating parameter curve and the standard parameter curve, the difference between the vehicle's current operating condition and its ready state can be precisely identified. This improves the accuracy and efficiency of detection, ensuring that the vehicle reaches its optimal testing preparation state before annual inspection or other compliance tests. This solves the problem in existing technologies where vehicle control strategies cannot track and record the vehicle's ready state after fault clearing.

[0028] In this embodiment, in step S3, if the current operating condition of the vehicle does not meet the ready operating condition, the vehicle ready state control method further includes:

[0029] At least one of the following: speed report, throttle report, and gear information for groups that do not meet the ready operating condition is output to the driver of the vehicle to guide the driver to adjust the current operating condition of the vehicle.

[0030] Specifically, by outputting the vehicle speed, throttle, and gear information corresponding to groups that failed to achieve readiness status to the driver, the driver can adjust driving habits or driving conditions based on this information to achieve ideal operating conditions for specific monitoring functions. This promotes the effective completion of the vehicle monitoring system's readiness status, ensuring that the vehicle can provide accurate fault monitoring data in subsequent inspections, meet regulatory requirements, and successfully pass annual inspections or other routine checks. Simultaneously, this control method improves the efficiency of achieving readiness status by directly interacting with the driver and outputting specific operational adjustment suggestions.

[0031] In this embodiment, the method for comparing the consistency of the current CVN value and the historical CVN value in a preset order, obtaining the historical readiness status completion of the vehicle's storage module, and obtaining the relationship between the vehicle's engine operating parameter curve and the standard parameter curve within a preset time t includes:

[0032] First, compare the consistency between the current CVN value and the historical CVN value, and obtain the historical readiness status completion of the vehicle's storage module. If the current CVN value and the historical CVN value are consistent and the historical readiness status of the vehicle's storage module is completed, then obtain the relationship between the vehicle's engine operating parameter curve and the standard parameter curve within a preset time t.

[0033] Specifically, the first step involves comparing the current CVN value (software version code) with historical CVN values ​​to ensure the correctness of the vehicle's electronic control unit (ECU) software version. This CVN value check, as the first hurdle in confirming readiness, effectively prevents monitoring function failures due to software version errors or unauthorized software updates, guaranteeing the fundamental stability and data reliability of the entire readiness control process. Simultaneously, by following a preset sequence, the comparison and analysis of the operating parameter curves within a preset time t with the standard parameter curves are only performed after confirming CVN value consistency and the completion of historical readiness status. This sequential processing method reduces unnecessary data processing and resource consumption. Especially when historical readiness status is incomplete or CVN values ​​are inconsistent, it can be directly determined that the vehicle has not reached the ready condition without further analysis of the operating parameter curves. This not only improves the execution efficiency of the control method but also avoids redundant analysis of vehicle operating data, ensuring the simplification and effectiveness of the entire readiness control process.

[0034] In this embodiment, the method for determining whether the current operating condition of the vehicle meets the ready condition includes:

[0035] If the difference between the engine operating parameter curve and the standard parameter curve of the vehicle is always less than the preset difference within a preset time t, then it is determined that the current operating condition of the vehicle does not meet the ready condition.

[0036] Specifically, by quantifying the difference between the operating parameter curve and the standard parameter curve, and setting a preset difference threshold, it is possible to accurately determine whether the vehicle's current operating condition meets the necessary conditions for achieving a ready state. If the difference is consistently less than the preset difference, it means that the operating condition within the preset time t has failed to fully activate the vehicle's monitoring system to achieve the ready state required by regulations or the manufacturer. If it is determined that the vehicle's current operating condition does not meet the ready condition requirements, specific guidance suggestions can be directly provided, such as adjusting vehicle speed, throttle, or gear, to help the driver achieve the operating conditions that meet the monitoring system's operating requirements. This not only simplifies the driver's understanding of the ready condition requirements but also provides a highly operable solution, helping the driver quickly identify and adjust the operating condition, thereby accelerating the achievement of the ready state, ensuring the effective operation of the vehicle's monitoring system, meeting regulatory requirements, and improving the vehicle's inspection pass rate.

[0037] In this embodiment, the method for guiding the driver to adjust the vehicle's current operating conditions includes:

[0038] The system will present at least one of the following information to the driver: speed report, throttle report, and gear information for groups that do not meet the ready condition requirements. This information will be presented to the driver through an interactive interface such as SmartStar or a mobile app, and the driver will be guided to perform the corresponding operation test to complete the ready condition.

[0039] Specifically, based on the specific reasons why each group failed to reach a ready state, this method can generate personalized operational test guidance. Drivers will receive targeted suggestions for adjusting vehicle speed, throttle, or gear, ensuring the monitoring system reaches a ready state under various vehicle configurations and usage environments, thereby improving the overall adaptability and reliability of the vehicle monitoring system. Simultaneously, through interactive interfaces such as smart speakers or mobile apps, the information is presented in a more intuitive and understandable way, potentially including graphical displays, animated tutorials, or voice guidance to help drivers quickly master the skills of adjusting vehicle operating conditions and avoid confusion caused by complex technical jargon. This user-experience-focused design approach reduces the learning cost for drivers, increasing their willingness and success rate in performing operational tests.

[0040] Optionally, the method for controlling the vehicle's ready state further includes step S01, which precedes step S1:

[0041] The vehicle's control module CVN value is read and compared with historical CVN values ​​stored in the storage module to confirm the consistency of the control module's software version.

[0042] Specifically, comparing CVN values ​​(Version Check Numbers) is a crucial step in confirming software version consistency. Before fault clearing and readiness reset, verifying that the control module's software version matches the historical version recorded in the storage module effectively prevents monitoring malfunctions or missed faults due to software version inconsistencies. Furthermore, by confirming software version consistency at an early stage, i.e., step S01, if a CVN value mismatch is found, immediate action can be taken, such as updating or reinstalling the correct version, without proceeding to the subsequent readiness monitoring process. This avoids unnecessary condition testing and repetitive work, improving overall maintenance efficiency.

[0043] Optionally, the method for controlling the vehicle's ready state further includes step S02, which precedes step S01:

[0044] Collect environmental factors during vehicle operation and determine the degree of influence of these environmental factors on the engine's operating parameter curves, so as to adjust the standard parameter curves according to the degree of influence; among them, environmental factors include at least one of ambient temperature, ambient humidity, and altitude.

[0045] Specifically, the performance of a vehicle's engine may be affected by operating under different environmental conditions. For example, low ambient temperatures may lead to poor cold-start performance, and thin air at high altitudes may affect combustion efficiency. Step S02 collects key environmental factors such as ambient temperature, humidity, and altitude in real time, assesses the degree of influence of these factors on engine operating parameters, and dynamically adjusts the standard parameter curves accordingly to make the standard parameters closer to the actual operating environment. This improves the accuracy of readiness status judgment, avoids misjudgments or omissions caused by environmental factors, and ensures the reliability and effectiveness of the monitoring system.

[0046] This application also provides a control device (not shown) for a vehicle ready state, the control device including a memory and a processor. The memory stores relevant program code, and the processor calls the program code to execute the aforementioned vehicle ready state control method.

[0047] This application also provides a computer-readable storage medium for storing a computer program for executing the above-described vehicle readiness state control method.

[0048] This application also provides a computer program product comprising a program that, when run on a processor, causes a computer or network device to execute the aforementioned vehicle readiness state control method.

[0049] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0050] By using a service tool to clear faults in the vehicle and reset its ready state, followed by driving the vehicle for a preset time t and recording key parameters, this control method can efficiently and accurately detect the vehicle's ready state after fault clearance. In particular, in step S3, the ready state of each group is judged one by one. If the vehicle is not fully ready, by comparing the CVN value, historical ready state, and the relationship between the operating parameter curve and the standard parameter curve, the difference between the vehicle's current operating condition and its ready state can be precisely identified. This improves the accuracy and efficiency of the detection, ensuring that the vehicle reaches its optimal preparation state before annual inspection or other compliance tests. This solves the problem in existing vehicle control strategies that cannot track and record the vehicle's ready state after fault clearance.
