[0002] Electric power steering (EPS) uses the power generated by an electric motor to assist the driver in steering operations. EPS provides steering assistance to the driver, ensuring that the car is easy and flexible when turning at low speeds and stable and reliable when turning at high speeds.

[0003] In the typical automobile production process, because various component platforms need to complete mutual verification and matching with the vehicle controller, the electric power steering system is still in an unstable state on the automobile production line and cannot provide steering assistance normally.

[0004] In this situation, if a special circumstance arises requiring an emergency removal of a vehicle from the production line, the incomplete configuration of the electric power steering system will prevent it from providing steering assistance to the driver, resulting in the problematic vehicle remaining on the production line.

[0026] If the parameter value of the median calibration configuration code is 0, it is determined that the electric power steering system has not completed the second configuration process.

[0027] If the parameter value of the mid-position calibration configuration code is 1, it is determined that the electric power steering system has completed the second configuration process.

[0031] If only one of the first modification operation or the second modification operation can be found, or if neither the first modification operation nor the second modification operation can be found, the electric power steering system is in the configuration pending state.

[0032] If both the first modification operation and the second modification operation can be found, the electric power steering system is not in the configuration state.

[0049] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0050] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0051] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0052] In order to provide a clearer description of the technical solutions provided in the embodiments of this application, before describing the technical solutions provided in the embodiments of this application, a possible implementation scenario of the technical solutions provided in the embodiments of this application will be described first, and the general structure and function of the electric power steering system will be described at the same time.

[0053] The steering assist method provided in this application embodiment can be applied to an electric power steering system, specifically in the electronic controller of the electric power steering system.

[0054] In some possible implementation scenarios, the general process of assembling a car on an automotive production line can be described as follows: production personnel assemble the component platforms obtained from suppliers onto the vehicle frame; after each component platform is powered on and running, production personnel configure each component platform using relevant configuration equipment; after each component platform is configured, mutual verification is performed between each component platform and between each component platform and the vehicle body integration controller; after successful verification between each component platform and between each component platform and the vehicle body integration controller, the vehicle production configuration is completed, the vehicle rolls off the production line, and other production steps continue.

[0055] On the automotive production line, each component platform needs to complete mutual verification with other component platforms and the vehicle body integrated controller before it can perform its corresponding functions. For example, the electric power steering system, as one of several component platforms, cannot provide steering assistance to the car before it has completed mutual verification with other component platforms.

[0056] Therefore, if a special situation occurs on the automobile production line, and production personnel need to urgently move a car that has completed the assembly of the component platforms but has not completed the mutual verification between the component platforms, the electric power steering system will not be able to provide steering assistance to the car because the mutual verification between the component platforms has not been completed. This will make it difficult to move the car urgently, and the car will be stuck on the automobile production line, which will affect the production efficiency of the automobile production line.

[0057] Figure 1 A schematic diagram of an electric power steering system is provided. In some possible examples, the general structure of the electric power steering system is as follows: Figure 1 As shown. (Refer to...) Figure 1 An electric power steering system mainly includes an electronic controller, an information sensing unit, and a steering assist unit. Specifically, the information sensing unit mainly includes a torque sensor and a speed sensor. The torque sensor is connected to the steering wheel (i.e., the steering wheel) via the steering shaft. When the driver turns the steering wheel, the torque sensor can detect the torque information transmitted by the steering shaft. The speed sensor is used to obtain the vehicle's speed information during driving. The electronic controller is connected to the information sensing unit and is used to receive the torque and speed information from the information sensing unit. It processes the torque and speed information to determine the steering assist required by the vehicle under the current torque and speed, and sends the information describing the steering assist to the steering assist unit. The steering assist unit is connected to the electronic controller and mainly includes a motor, a clutch, and a reduction gear mechanism. The steering assist unit is used to generate steering assist based on the information describing the steering assist sent by the electronic controller, providing steering assistance to the vehicle.

[0058] Simultaneously, the electric power steering system is also connected to a starting unit, which controls the starting status of the electric power steering system. When the starting unit receives a starting signal, it transmits the signal to the electronic controller of the electric power steering system, and the electric power steering system begins to operate. Specifically, the starting signal can be KL15 (engine ignition signal).

[0059] To address the technical problem that electric power steering systems in automobiles on the production line cannot properly provide steering assistance to drivers, making it difficult to achieve emergency vehicle relocation during the production process, this application provides a steering assistance method, device, electronic device, and storage medium to activate the electric power steering system when emergency vehicle relocation is required during automobile production, enabling the electric power steering system to provide steering assistance to the driver in emergency vehicle relocation situations.

[0060] Figure 2 A flowchart illustrating a method for providing steering assistance, as provided in this application embodiment, is shown below. Figure 2 The method for providing steering assistance provided in this application embodiment specifically includes the following steps:

[0061] S1: In response to the power-on signal, obtain configuration information; wherein, the configuration information is used to describe the current configuration of the electric power steering system;

[0062] Specifically, after the electric power steering system is assembled onto the car frame and powered on, it generates a power-on signal. This power-on signal can be generated by the electric power steering system itself or by the vehicle's integrated body controller. After the electric power steering system detects the power-on signal, its electronic controller acquires the configuration information.

[0063] The configuration information describes the current configuration status of the electric power steering system. The specific configuration information is obtained from the control software installed in the electronic controller of the electric power steering system.

[0064] Based on the above description of possible implementation scenarios for this application, the configuration of the electric power steering system occurs after the electric power steering system is assembled onto the vehicle frame. After the electric power steering system is assembled onto the vehicle frame, production personnel re-update the control software to make it compatible with the current vehicle. Since the electric power steering system is in its supplier's factory-installed state before assembly onto the vehicle frame, the control software installed in the electronic controller of the electric power steering system is also in its factory-installed state. The configuration files in the control software are all the supplier's default configuration files. Re-updating the control software includes modifying the default configuration files in the control software to make it compatible with the current vehicle.

[0065] In one feasible embodiment of this application, obtaining configuration information includes:

[0066] Iterate through the configuration files of the electric power steering system; each configuration file contains multiple configuration information.

[0067] Obtain the first configuration information from the configuration file; the first configuration information includes the vehicle model parameter configuration code;

[0068] Obtain the second configuration information from the configuration file; the second configuration information includes the median calibration configuration code.

[0069] Specifically, first configuration information and second configuration information are obtained from the control software in the electronic controller of the electric power steering controller. The first configuration information includes a vehicle model parameter configuration code, and the second configuration information includes a median calibration configuration code. In one feasible embodiment of this application, the first and second configuration information can be obtained by file traversal.

[0070] In one feasible embodiment of this application, the configuration information can be stored in the configuration file of the control software installed in the electronic controller of the electric power steering system. These configuration files can be stored in the control software in formats such as XML (Extensible Markup Language), JSON (JavaScript Object Notation), CSV (Comma-Separated Values), or text files.

[0071] The configuration of an electric power steering system includes its center calibration. Center calibration (or steering wheel center calibration) refers to the adjustment of the electric power steering system so that the steering assistance output is zero when the system is in the neutral position.

[0072] This is reflected in the control software installed in the electronic controller of the electric power steering system. The configuration file in the control software contains a center calibration configuration code. After the production personnel complete the center calibration of the electric power steering system, they modify the parameter value of the center calibration configuration code to a specific value, indicating that the center calibration of the electric power steering system has been completed.

[0073] The configuration of the electric power steering system also includes configuring the vehicle model parameters for the system. This involves modifying the vehicle model parameter configuration code in the control software of the electric power steering system's electronic controller to ensure that the configuration code matches the vehicle model parameters in the integrated vehicle controller's software.

[0074] This is reflected in the control software installed in the electronic controller of the electric power steering system. The configuration file in the control software of the electronic controller of the electric power steering system contains the vehicle model parameter configuration code. After the production personnel complete the configuration of the vehicle model parameters of the electric power steering system, they modify the parameter value of the mid-calibration configuration code to be consistent with the vehicle model parameters in the control software of the vehicle body integrated controller, indicating that the configuration of the vehicle model parameters of the electric power steering system has been completed.

[0075] S2: Determine whether the electric power steering system is currently in a configuration-pending state based on the configuration information;

[0076] Specifically, after obtaining the configuration information of the electric power steering system, a judgment is made based on the configuration information to determine whether the electric power steering system is currently in a pending configuration state, and the judgment result is obtained. The judgment result is either that the electric power steering system is in a pending configuration state or that the electric power steering system is not in a pending configuration state.

[0077] It is understood that the technical solution provided in this application is applied to emergency vehicle relocation on the automobile production line. That is, the technical solution only aims to provide steering assistance for automobiles that have not completed the component platform configuration. Therefore, the technical solution provided in this application needs to determine the configuration of the electric power steering system based on the configuration information.

[0078] In one feasible embodiment of this application, determining whether the electric power steering system is currently in a configuration-pending state based on the configuration information includes:

[0079] Based on the first configuration information, determine whether the current electric power steering system has completed the first configuration process; wherein, the first configuration process is: configuring the vehicle parameter configuration code of the electric power steering system;

[0080] Based on the second configuration information, determine whether the current electric power steering system has completed the second configuration process; wherein, the first configuration process is: mid-position calibration of the electric power steering system;

[0081] If either the first configuration process or the second configuration process is not completed, the electric power steering system is in a state of pending configuration.

[0082] If both the first and second configuration processes are completed, the electric power steering system is not in a state of pending configuration.

[0083] Specifically, the configuration information describes the current configuration of the electric power steering system. In the technical solution provided in this application, the configuration process of the electric power steering system includes a first configuration process and a second configuration process. The first configuration process is the mid-calibration of the electric power steering system mentioned in the foregoing embodiments, and the second configuration process is the mid-calibration of the electric power steering system mentioned in the foregoing embodiments.

[0084] The configuration information includes first configuration information and second configuration information. The first configuration information describes the configuration of the first configuration process, and the second configuration information describes the configuration of the second configuration process. After determining the configuration of the first and second configuration processes, the current configuration of the electric power steering system can be determined based on these configurations.

[0085] In this embodiment, if both the first and second configuration processes are completed, the production personnel have completed the configuration and midpoint calibration of the vehicle parameter configuration code for the electric power steering system, indicating that the electric power steering system has been configured and is not in a state of pending configuration. If either the first or second configuration process is not completed, and the production personnel are still performing either the configuration process for the vehicle parameter configuration code or the midpoint calibration of the electric power steering system, it indicates that the electric power steering system has not been configured and is in a state of pending configuration.

[0086] In one feasible embodiment of this application, determining whether the current electric power steering system has completed the first configuration process based on the first configuration information includes:

[0087] Verify the parameter values ​​of the vehicle model configuration code;

[0088] If the parameter value of the vehicle parameter configuration code is 0, it is determined that the current electric power steering system has not completed the first configuration process;

[0089] If the parameter value of the vehicle parameter configuration code is not 0, it is determined that the electric power steering system has completed the first configuration process.

[0090] Specifically, as explained in the foregoing embodiments, before the electric power steering system is assembled onto the vehicle frame but before configuration is completed, the control software in the electronic controller of the electric power steering system is in its factory default state, and the first configuration information in the control software is also in its factory default state. The parameter values ​​of the vehicle model parameter configuration code included in the first configuration information are factory default values. By verifying the parameter values ​​of the vehicle model parameter configuration code, it can be determined whether the electric power steering system has completed the first configuration process.

[0091] In one feasible embodiment of this application, the factory default value of the vehicle model parameter configuration code is 0. After completing the first configuration process, the parameter value of the vehicle model parameter configuration code is configured to be consistent with the vehicle model configuration specified by the vehicle body integrated controller. If the parameter value of the vehicle model parameter configuration code is 0, it is determined that the current electric power steering system has not completed the first configuration process; if the parameter value of the vehicle model parameter configuration code is not 0, it is determined that the current electric power steering system has completed the first configuration process.

[0092] In one feasible embodiment of this application, determining whether the current electric power steering system has completed the second configuration process based on the second configuration information includes:

[0093] Verify the parameter values ​​of the midpoint calibration configuration code;

[0094] If the parameter value of the mid-calibration configuration code is 0, it is determined that the current electric power steering system has not completed the second configuration process;

[0095] If the parameter value of the mid-position calibration configuration code is 1, it is determined that the current electric power steering system has completed the second configuration process.

[0096] Specifically, as explained in the foregoing embodiments, before the electric power steering system is assembled onto the vehicle frame but before configuration is completed, the second configuration information is also at the factory default value. Only after the second configuration process is completed is the median calibration configuration code in the second configuration information modified to a specific value. By verifying the parameter value of the median calibration configuration code, it can be determined whether the current electric power steering system has completed the second configuration process.

[0097] In one feasible embodiment of this application, the factory default value of the median calibration configuration code is 0. After completing the second configuration process, the production personnel set the parameter value of the median calibration configuration code to a specific value of 1. When the parameter value of the median calibration configuration code is 0, it is determined that the current electric power steering system has not completed the second configuration process; when the parameter value of the median calibration configuration code is 1, it is determined that the current electric power steering system has completed the second configuration process.

[0098] The process for determining whether the electric power steering system is in a pending configuration state in the above embodiment is quite cumbersome. It requires first obtaining the first configuration information and the second configuration information, then verifying the first configuration information and the second configuration information, determining whether the first configuration process and the second configuration process are completed based on the parameter values ​​of the first configuration information and the second configuration information, and determining whether the electric power steering system is in a pending configuration state based on the completion status of the first configuration process and the second configuration process.

[0099] To simplify the process of determining whether the electric power steering system is in a pending configuration state, in one feasible embodiment of this application, determining whether the electric power steering system is currently in a pending configuration state based on the configuration information can also be achieved in the following way:

[0100] Retrieve modification operation records; these records are used to document modifications made to the configuration file.

[0101] The first modification operation and the second modification operation are found in the modification operation record respectively; wherein, the first modification operation is the modification operation performed on the first configuration information in the configuration file, and the second modification operation is the modification operation performed on the second configuration information in the configuration file;

[0102] If only one of the first modification operation or the second modification operation can be found, or if neither the first modification operation nor the second modification operation can be found, the electric power steering system is in a configuration pending state.

[0103] If both the first and second modification operations can be found, the electric power steering system is not in a configuration pending state.

[0104] Specifically, a log mechanism is introduced into the control software of the electric power steering system. When the configuration file in the control software is modified, a modification operation record corresponding to the modification operation is generated. The modification operation record is different from the configuration file and is stored as an independent file in the control software of the electric power steering system.

[0105] The modification operation log records the object, time, and content of each modification operation. The first modification operation modifies the first configuration information in the configuration file, and the second modification operation modifies the second configuration information in the configuration file. If the modification object of any modification operation in the modification operation log is the first configuration information, then that modification operation is designated as the first modification operation. Similarly, if the modification object of any modification operation in the modification operation log is the second configuration information, then that modification operation is designated as the second modification operation.

[0106] When determining whether an electric power steering system is in a pending configuration state, it is only necessary to check the modification operation record for the existence of a first modification operation and a second modification operation. For example, if neither the first nor the second modification operation can be found, it means that neither the first nor the second configuration information in the electric power steering system's configuration file has been modified. Therefore, it can be assumed that the electric power steering system has not completed the first and second configuration processes, and is currently in a pending configuration state. Conversely, if both the first and second modification operations can be found, it means that both the first and second configuration information in the electric power steering system's configuration file have been modified. Therefore, it can be assumed that the electric power steering system has completed the first and second configuration processes, and is not currently in a pending configuration state.

[0107] In one feasible embodiment of this application, the modification operation record can also be recorded on the configuration device. The configuration device is a device used by production personnel to configure the electric power steering system. After the configuration device completes the judgment process of whether the electric power steering system is in a state to be configured as described in the above embodiment, it can directly inform the electronic controller of the electric power steering system of the current configuration status of the electric power steering system, thereby saving the computing power of the electronic controller of the electric power steering system.

[0108] S3: When the electric power steering system is in the configuration state, the power steering mode of the electric power steering system is controlled to be the factory power steering mode; in the factory power steering mode, the electric power steering system provides default steering assistance.

[0109] Specifically, when the electric power steering system is in the configuration state, the system switches the power steering mode to the factory power steering mode, in which the electric power steering system provides default steering assistance.

[0110] In factory-assisted mode, in response to the start signal (i.e. KL15), the electric power steering can start working as long as the operating voltage meets the working voltage of the electric power steering system, providing default steering assistance for emergency vehicle maneuvering.

[0111] In one feasible embodiment of this application, the electric power steering system in factory-assisted mode provides default steering assistance through the following steps:

[0112] In factory power steering mode, in response to the start signal, torque information and default speed information are acquired; the torque information is acquired through the torque sensor in the electric power steering system, and the default speed information is the preset speed information.

[0113] The default steering assist is determined in the preset steering assist table based on the torque information and the default speed information.

[0114] Specifically, when a car is running normally off the production line, the electric power steering system provides steering assistance based on the torque of the steering wheel and the speed of the car. However, in the technical solution provided in this application, since the electric power steering system of the car on the production line has not yet been configured, it is impossible to accurately provide steering assistance based on torque and speed. Therefore, the steering assistance provided when the power steering system is in the factory power steering mode is set as the default steering assistance.

[0115] When the electric power steering system is in factory assist mode, it provides steering assistance in response to the start signal. Specifically, the start signal is KL15, generated by the ignition of the vehicle by production personnel during emergency vehicle relocation. This start signal is input to the electronic controller of the electric power steering system via the start unit, and the electronic controller responds to the start signal and begins to execute the actual functions.

[0116] When the electric power steering system is in factory assist mode, torque information is acquired from the torque sensor in the system, along with default speed information. This default speed information can be preset in the control software of the electronic controller or input by production personnel via production equipment. In some possible embodiments, the default speed is set to 30 km / h. After acquiring the torque and default speed information, the steering assist currently provided by the electric power steering system is determined as the default steering assist based on these parameters.

[0117] When determining the default steering assist based on torque and default speed information, the system searches a pre-set steering assist table in the electronic controller of the electric power steering system for the corresponding steering assist value. The steering assist table describes the correspondence between speed information, torque information, and steering assist value. Based on the determined speed and torque information, the system can find the corresponding steering assist value in the steering assist table using the torque and default speed information, and then determine that steering assist value as the default steering assist.

[0118] In one feasible embodiment of this application, a default steering assist can also be directly determined for the electric power steering system. When the power assist mode of the electric power steering system is the factory assist mode, production personnel can directly set the default steering assist for the electric power steering system through production equipment.

[0119] To identify the current electric power steering system's assist mode as factory mode, and to simultaneously notify production personnel that the current electric power steering system has not yet completed vehicle parameter configuration and / or mid-range calibration, in one feasible embodiment of this application, after controlling the electric power steering system's assist mode to factory assist mode when the electric power steering system is in a pending configuration state, the method further includes:

[0120] Generate a warning message; the warning message is used to illuminate the malfunction indicator light for the electric power steering system.

[0121] Specifically, when the electric power steering system is in factory assist mode, the electronic controller of the electric power steering system generates a prompt message and illuminates the electric power steering system's fault light to indicate that the current electric power steering system is in factory assist mode and that the electric power steering system has not completed vehicle parameter configuration and / or mid-calibration.

[0122] When the electric power steering system is in normal power steering mode, no further warning messages will be generated, and the malfunction indicator light for the electric power steering system will turn off.

[0123] As can be seen from the foregoing description of the embodiments, the technical solution provided in this application is used for emergency vehicle relocation on the automobile production line. If steering assistance is still provided through the technical solution provided in this application after the automobile has rolled off the production line and been put into normal use, it will conflict with the steering assistance logic provided during normal use of the electric power steering system.

[0124] To address the aforementioned issues, in one feasible embodiment of this application, the method further includes, after determining whether the electric power steering system is in a pending configuration state based on configuration information:

[0125] When the electric power steering system is not in the configuration state, the power steering mode of the electric power steering system is controlled to be the normal power steering mode.

[0126] Specifically, the execution condition of the technical solution provided in this application is that the electric power steering system receives a power-on signal. In addition to the power-on of the electric power steering system on the automobile production line, in some possible after-sales scenarios, the electric power steering system will also receive a power-on signal after after-sales personnel remove, repair, or install the electric power steering system.

[0127] In after-sales scenarios, after-sales personnel will also configure and calibrate the electric power steering system for vehicle parameters. However, unlike the configuration and calibration of vehicle parameters on the automobile production line, the configuration and calibration of vehicle parameters in the after-sales process will not result in the vehicle parameter configuration code being 0, nor will it result in the calibration configuration code being 0. As a result, the electronic controller of the electric power steering system will determine that the electric power steering system is not in a state of waiting to be configured, and the power steering mode of the electric power steering system will be the normal power steering mode.

[0128] Figure 3 This is an overall flowchart of a method for providing steering assistance provided in an embodiment of this application, combined with... Figure 3 The overall process of the technical solution provided in this application is described.

[0129] Reference Figure 3 The method for providing steering assistance provided in this application specifically includes:

[0130] On the automotive production line, after the production staff installs the electric power steering system onto the car frame, the electric power steering system receives a power-on signal. In response to the power-on signal, it acquires configuration information, specifically including first configuration information and second configuration information. The first configuration information includes a vehicle model parameter configuration code, and the second configuration information includes a center calibration configuration code. The system checks whether the parameter value of the vehicle model parameter configuration code is 0 to determine if the electric power steering system has completed the first configuration process. It also checks whether the parameter value of the center calibration configuration code is 0 to determine if the electric power steering system has completed the second configuration process. If either the first or second configuration process is incomplete, the electric power steering system is designated as being in a pending configuration state. When the electric power steering system is in a pending configuration state, its power steering mode is set to factory power steering mode. If both the first and second configuration processes are completed, the electric power steering system is not designated as being in a pending configuration state. When the electric power steering system is not in a pending configuration state, its power steering mode is set to normal power steering mode.

[0131] The technical solution provided in this application, after the electric power steering system is installed and powered on, acquires the configuration information of the electric power steering system to determine its current configuration status. Based on the configuration information, it determines whether the electric power steering system is currently in a pending configuration state. If the electric power steering system is in a pending configuration state, it controls the power steering mode to factory power steering mode, in which the electric power steering system provides default steering assistance. Through the technical solution provided in this application, after the electric power steering system is installed and powered on, the current power steering mode is determined based on the determination of the electric power steering system's configuration status. In special circumstances requiring emergency relocation of a vehicle from the production line, technicians can temporarily obtain the default steering assistance of the electric power steering system through the activated factory power steering mode, providing assistance for emergency relocation. It is understood that the technical solution provided in this application can also provide default steering assistance to technicians when the electric power steering system is in a pending configuration state, solving the technical problem that it is difficult to achieve emergency relocation during the production process because the electric power steering systems in vehicles on the production line cannot normally provide steering assistance to the driver.
