Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a vehicle steering style request signal processing method, a domain controller, a steering style switching system, a vehicle, and a storage medium. Background Technology

[0002] With the increasing popularity of cars, vehicles are becoming more and more personalized. Personalization is generally reflected in providing users with customizable settings, such as the steering style switching function. Different steering styles result in different steering wheel feel. The steering wheel feel is the most direct bridge between the driver and the car, and steering feel is specific, mainly in two aspects: 1. For the same vehicle, different people will have different steering feel requirements; 2. For the same person, there will be different steering feel requirements for different vehicles.

[0003] Generally, the steering style switching function is integrated into the ECU of the steering controller, such as the electric power steering controller (EPS). The EPS ECU is responsible for judging the steering style request and executing the steering style switching. With increasing demands for user experience in vehicles, the requirements for this function change frequently, leading to frequent software modifications. However, the implementation cycle for these changes by component suppliers is long, often forcing OEMs to cancel some requirements due to time constraints. This restricts the overall vehicle development work and progress to some extent, limiting the freedom and increasing the cost of updating or further developing the steering style switching function. Summary of the Invention

[0004] Therefore, it is necessary to provide a vehicle steering style request signal processing method, a domain controller, a steering style switching system, a vehicle, and a storage medium to address the above-mentioned technical problems, so as to improve the freedom of updating or further developing the steering style switching function and reduce costs.

[0005] A vehicle steering style request signal processing method, applied to a vehicle's domain controller, the method comprising:

[0006] Receive a steering style request signal, and determine whether a target request signal exists in the steering style request signal; and

[0007] Obtain the current driving status signal, and determine whether the current driving status meets the steering style switching conditions based on the current driving status signal; if not, end the current processing process.

[0008] If the target request signal exists and the current driving state meets the steering style switching conditions, then the validity of the target request signal is determined, and the steering style parameters corresponding to the valid target request signal are sent to the steering controller so that the steering controller can switch the vehicle steering style according to the steering style parameters.

[0009] In this embodiment of the application, determining whether a target request signal exists in the steering style request signal includes:

[0010] From the received steering style request signals, the steering style request signal with the highest processing priority is selected as the candidate request signal;

[0011] In response to the presence of a target request signal being processed in the processing process of the domain controller, it is determined whether the processing priority of the candidate request signal is higher than the processing priority of the target request signal being processed.

[0012] If the processing priority of the candidate request signal is higher than the processing priority of the target request signal being processed, then the processing of the target request signal being processed is terminated, and the candidate request signal is confirmed as a new target request signal.

[0013] If the processing priority of the candidate request signal is lower than or equal to the processing priority of the target request signal in the process, then it is confirmed that the target request signal does not exist in the steering style request signal.

[0014] In response to the absence of a target request signal being processed in the domain controller's processing flow, the candidate request signal is confirmed as the target request signal.

[0015] In this embodiment of the application, the step of selecting the steering style request signal with the highest processing priority from the received steering style request signals as candidate request signals includes:

[0016] Determine whether the number of received steering style request signals is greater than 1;

[0017] If the number of steering style request signals is 1, then the steering style request signal is determined as the candidate request signal;

[0018] If the number of steering style request signals is greater than 1, then based on the processing priority of the steering style request signals, the steering style request signal with the highest processing priority is selected from the steering style request signals as the candidate request signal.

[0019] The processing priority is determined by the priority of the signal source and the priority of the signal request's steering style.

[0020] In this embodiment of the application, the priority of the signal source is as follows: the priority of the steering style request signal sent by the driving assistance component based on intelligent decision is higher than the priority of the steering style request signal sent by the interaction component based on user operation;

[0021] The priority of the steering style request signal sent by the interactive component based on user operation is higher than the priority of the steering style request signal triggered by driving mode switching.

[0022] The steering style includes the steering style corresponding to the preset steering mode and the steering style corresponding to the custom steering assist percentage. The priority of the steering style is: the steering style corresponding to the custom steering assist percentage has a higher priority than the steering style corresponding to the preset steering mode.

[0023] In this embodiment of the application, determining the validity of the target request signal includes:

[0024] Determine whether the vehicle's current steering style parameters are the same as the steering style parameters corresponding to the target request signal;

[0025] If they are the same, then the target request signal is determined to be invalid;

[0026] If they are different, then the target request signal is determined to be valid.

[0027] In this embodiment of the application, the current steering style parameter of the vehicle includes an identifier of the current steering mode and a value of the current steering assist percentage; the steering style parameter corresponding to the target request signal includes an identifier of the steering mode or a value of the steering assist percentage; and determining whether the current steering style parameter of the vehicle and the steering style parameter corresponding to the target request signal need to be the same includes:

[0028] When the target request signal is a steering assist percentage adjustment request signal, determine whether the value of the steering assist percentage corresponding to the target request signal is the same as the current steering assist percentage value of the vehicle.

[0029] When the target request signal is a steering mode switching request signal, it is determined whether the identifier of the steering mode corresponding to the target request signal is the same as the identifier of the vehicle's current steering mode.

[0030] In this embodiment of the application, before determining whether the current steering style parameters of the vehicle are the same as the steering style parameters corresponding to the target request signal, the method further includes:

[0031] When the target request signal is a steering style request signal triggered by driving mode switching, the driving mode after switching is determined based on the target request signal;

[0032] Based on the switched driving mode and the preset mapping relationship, the steering style parameter corresponding to the switched driving mode is determined as the steering style parameter corresponding to the target request signal. The preset mapping relationship is the correspondence between the driving mode and the steering style parameter.

[0033] A domain controller for a vehicle, comprising:

[0034] The signal priority determination module receives a steering style request signal and determines whether a target request signal exists in the steering style request signal; and

[0035] The condition judgment module is used to acquire the current driving state signal and determine whether the current driving state meets the steering style switching conditions based on the current driving state signal; if not, the current processing process ends.

[0036] The validity determination module determines the validity of the target request signal if the target request signal exists and the current driving state meets the steering style switching conditions. It then sends the steering style parameters corresponding to the valid target request signal to the steering controller so that the steering controller can switch the vehicle steering style according to the steering style parameters.

[0037] In this embodiment of the application, the signal priority determination module is further used for:

[0038] From the received steering style request signals, the steering style request signal with the highest processing priority is selected as the candidate request signal;

[0039] In response to the presence of a target request signal being processed in the processing process of the domain controller, it is determined whether the processing priority of the candidate request signal is higher than the processing priority of the target request signal being processed.

[0040] If the processing priority of the candidate request signal is higher than the processing priority of the target request signal being processed, then the processing of the target request signal being processed is terminated, and the candidate request signal is confirmed as a new target request signal.

[0041] If the processing priority of the candidate request signal is lower than or equal to the processing priority of the target request signal being processed, then it is confirmed that the target request signal does not exist in the steering style request signal.

[0042] In response to the absence of a target request signal being processed in the domain controller's processing flow, the candidate request signal is confirmed as the target request signal.

[0043] In this embodiment of the application, the signal priority determination module is further used for:

[0044] Determine whether the number of received steering style request signals is greater than 1;

[0045] If the number of steering style request signals is 1, then the steering style request signal is determined as the candidate request signal;

[0046] If the number of steering style request signals is greater than 1, then based on the processing priority of the steering style request signals, the steering style request signal with the highest processing priority is selected from the steering style request signals as the candidate request signal.

[0047] The processing priority is determined by the priority of the signal source and the priority of the signal request's steering style.

[0048] In this embodiment of the application, the priority of the signal source is as follows: the priority of the steering style request signal sent by the driving assistance component based on intelligent decision is higher than the priority of the steering style request signal sent by the interaction component based on user operation;

[0049] The priority of the steering style request signal sent by the interactive component based on user operation is higher than the priority of the steering style request signal triggered by driving mode switching.

[0050] The steering style includes the steering style corresponding to the preset steering mode and the steering style corresponding to the custom steering assist percentage. The priority of the steering style is: the steering style corresponding to the custom steering assist percentage has a higher priority than the steering style corresponding to the preset steering mode.

[0051] In this embodiment of the application, the validity determination module is further used for:

[0052] Determine whether the vehicle's current steering style parameters are the same as the steering style parameters corresponding to the target request signal;

[0053] If they are the same, then the target request signal is determined to be invalid;

[0054] If they are different, then the target request signal is determined to be valid.

[0055] In this embodiment, the vehicle's current steering style parameters include an identifier of the current steering mode and a value of the current steering assist percentage; the steering style parameters corresponding to the target request signal include either an identifier of the steering mode or a value of the steering assist percentage; and the validity determination module is further configured to:

[0056] When the target request signal is a steering assist percentage adjustment request signal, determine whether the value of the steering assist percentage corresponding to the target request signal is the same as the current steering assist percentage value of the vehicle.

[0057] When the target request signal is a steering mode switching request signal, it is determined whether the identifier of the steering mode corresponding to the target request signal is the same as the identifier of the vehicle's current steering mode.

[0058] In this embodiment of the application, the signal validity determination module is further used for:

[0059] When the target request signal is a steering style request signal triggered by driving mode switching, the driving mode after switching is determined based on the target request signal;

[0060] Based on the switched driving mode and the preset mapping relationship, the steering style parameter corresponding to the switched driving mode is determined as the steering style parameter corresponding to the target request signal. The preset mapping relationship is the correspondence between the driving mode and the steering style parameter.

[0061] A vehicle steering controller includes: an electronic processing unit;

[0062] The electronic processing unit is used to receive steering style parameters sent by the domain controller and switch the vehicle steering style according to the steering style parameters.

[0063] A vehicle steering style switching system, the system comprising the vehicle domain controller and the vehicle steering controller described in the above embodiments;

[0067] In summary, this application proposes a vehicle steering style request signal processing method, a domain controller, a steering style switching system, a vehicle, and a storage medium. Specifically, the processing of the steering style request signal is housed within the domain controller. The domain controller processes the received steering style request signals by: filtering out target request signals from the received signals; determining whether the steering style switching conditions are met; verifying the validity of the target request signal if the conditions are met and a target request signal exists; and sending the steering style parameters corresponding to the valid target request signal to the steering controller. This allows the steering controller to perform the steering style switching simply by receiving the steering style parameters. This application sets the personalization-related processing flow in the steering style switching function within the domain controller, enabling OEMs to independently and flexibly update the relevant processing logic in the domain controller, enhancing their development freedom for the steering style switching function and saving development time and costs.

[0079] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. The embodiments described with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0080] Figure 1 This is a flowchart illustrating a vehicle steering style request signal processing method according to an exemplary embodiment of this application, such as... Figure 1 As shown, the vehicle steering style request signal processing method includes the following steps:

[0081] S101, Receive steering style request signal, and determine whether there is a target request signal in the steering style request signal.

[0082] The vehicle steering style request signal processing method of this application can be applied to a domain controller, which receives the steering style request signal.

[0083] In some embodiments, the vehicle may be equipped with multiple components for switching steering styles, such as a scroll wheel on the steering wheel or a central control display. Users can use these components to switch or set the steering style according to their needs. These components send steering style request signals to the domain controller in response to user operations. The steering style can be set as needed; for example, a specific steering mode can be selected or a custom steering assist percentage value can be used to experience a particular steering style. This application does not impose any limitations.

[0084] In addition, in human-machine co-driving scenarios, advanced driver assistance systems can also issue steering style request signals to switch steering styles.

[0085] In this embodiment of the application, a target request signal is selected from one or more received steering style request signals. This application only needs to perform signal processing on the selected target request signal.

[0086] If the target request signal is not present in the received steering style request signals, then none of these steering style request signals will be processed.

[0087] S102, Obtain the current driving status signal, and determine whether the current driving status meets the steering style switching conditions based on the current driving status signal.

[0088] In this embodiment of the application, the current driving state is determined to meet the pre-set steering style switching conditions. If the conditions are met, the subsequent process steps are continued; if the conditions are not met, the steering style request signal received in step 1 is no longer processed.

[0089] In some embodiments, the aforementioned steering style switching condition is a constraint condition for safely implementing the steering style switching. The safety of switching the steering style under the current driving condition is determined based on this condition.

[0090] The types of current driving status signals can be set according to the steering style switching conditions. For example, they can be signals that can characterize the current operating condition of the vehicle.

[0091] In some embodiments, steering style switching conditions may include, but are not limited to, the following:

[0092] Condition 1: Is the vehicle speed less than 120 km / h? If yes, then condition 1 is satisfied; otherwise, condition 1 is not satisfied.

[0093] Condition 2: Is the steering wheel torque less than 3 Nm? If yes, then condition 2 is satisfied; otherwise, condition 2 is not satisfied.

[0094] Condition 3: Is the steering wheel rotation speed less than 360° / s? If yes, then condition 3 is satisfied; otherwise, condition 3 is not satisfied.

[0095] Correspondingly, the acquired current driving status signal can be the vehicle speed signal, the steering wheel torque signal, and the steering wheel speed signal.

[0096] When conditions 1, 2, and 3 are met simultaneously, the steering style switching conditions are considered met, and the steering style can be safely switched under the current driving conditions.

[0097] Furthermore, based on the above embodiments, the steering style switching conditions may also include: Condition 4, determining whether there is abnormal jitter in each steering style request signal or target request signal; if so, condition 4 is not satisfied, otherwise condition 4 is satisfied.

[0098] Correspondingly, when conditions 1, 2, 3 and 4 are all met, the conditions for switching the steering style are considered to be met.

[0099] In some embodiments, an identifier can be set for the judgment result of each condition, such as 1 if the condition is met and 0 if the condition is not met; thus, a status signal for the steering style switching condition is obtained. When the steering style switching condition is met, the status signal is 1, and when the steering style switching condition is not met, the status signal is 0. Based on the status signal of the steering style switching condition, it is more convenient to identify the judgment result of the steering style switching condition.

[0100] In some embodiments, the steering style switching condition determination process can be performed simultaneously with determining whether a target request signal exists in the received steering style request signal. For example, the current driving state signal can be obtained when a steering style switching request signal is received.

[0101] S103 If a target request signal exists and the current driving state meets the steering style switching conditions, the validity of the target request signal is determined, and the steering style parameters corresponding to the valid target request signal are sent to the steering controller so that the steering controller can switch the vehicle steering style according to the steering style parameters.

[0102] When a target request signal is present in the received steering style request signal, and the current driving state meets the steering style switching conditions, this application further determines the validity of the target request signal. The validity of the target request signal can be understood as whether the target request signal can trigger a new steering style setting, or whether it can trigger a steering style switch.

[0103] If the target request signal is valid, the steering style parameters corresponding to the valid target request signal are sent to the steering controller; if the target request signal is invalid, the subsequent processing procedure for that target request signal will not be performed.

[0104] In summary, this application sets the processing of steering style request signals in the domain controller. The domain controller processes the received steering style request signals as follows: it filters out target request signals from the received signals and determines whether the current driving state meets the steering style switching conditions. If the switching conditions are met and a target request signal exists, it verifies the validity of the target request signal and sends the steering style parameters corresponding to the valid target request signal to the steering controller. This allows the steering controller to perform steering style switching simply based on the received steering style parameters. This application processes the steering style request signals in the domain controller to determine the steering style parameters to be output to the steering controller. When further development or updates to the steering style are needed, such as adding new steering styles or associating steering styles with other personalized functions, OEMs can independently and flexibly develop new processing logic or update the relevant processing logic in the domain controller without requiring component suppliers to modify the steering controller's ECU. This enhances the OEM's freedom in developing steering style setting functions and saves development time and costs. This application reduces software changes to component ECUs, increasing their applicability. Furthermore, during the processing of steering style request signals, constraints on steering style switching conditions ensure the safety of steering style switching. Additionally, this application can simultaneously handle steering style request signals from multiple transmitters, filtering out the target request signal, thereby enabling vehicle-wide processing of steering style request signals.

[0105] Based on the above embodiments, such as Figure 2 As shown, step S101 above, "determining whether a target request signal exists in the steering style request signal," includes the following steps:

[0106] S201: Select the steering style request signal with the highest processing priority from the received steering style request signals and use it as a candidate request signal.

[0107] In this embodiment, the highest priority steering style request signal is selected from one or more received steering style request signals. This step determines the signals that require priority response, thereby improving the efficiency of signal processing.

[0108] The processing priority of the steering style request signal can be set as needed, and this application does not limit it. For example, the priority can be divided according to the sending end of the steering style request signal to determine which sending end's request should be responded to first; or, for another example, the priority can be divided according to the steering style requested by the steering style request signal.

[0109] For example, different senders may send steering style request signals with different identifiers, and these identifiers correspond to different processing priorities. Upon receiving a steering style request signal, its identifier is determined, and based on the correspondence between the identifier and the processing priority, the steering style request signal with the highest processing priority can be quickly selected.

[0110] S202, in response to the presence of a target request signal being processed in the processing process of the domain controller, determine whether the processing priority of the candidate request signal is higher than the processing priority of the target request signal being processed.

[0111] When a domain controller is responding to a target request signal, i.e., responding to a steering style request signal received in the previous stage, and then receives a new steering style request signal, it needs to determine whether there are any steering style request signals among these received steering style request signals that have a higher processing priority than the target request signal currently being responded to.

[0112] In some embodiments, it can be determined whether there is a target request signal being processed in the processing process of the domain controller, or it can be understood as whether there is a target request signal that the domain controller is responding to. If there is a target request signal being processed, that is, a target request signal that the domain controller is responding to, then it is determined whether the processing priority of the candidate request signal selected in the above steps is higher than the processing priority of the target request signal.

[0113] S203, if the processing priority of the candidate request signal is higher than the processing priority of the target request signal being processed, then the processing of the target request signal being processed is terminated, and the candidate request signal is confirmed as the new target request signal.

[0114] If among the newly received steering style processing request signals, there is a signal (i.e., the candidate request signal with the highest processing priority among these steering style request signals) with a processing priority higher than the target request signal that the domain controller is responding to (i.e., the target request signal in the above processing), then the processing of the target request signal is interrupted, and the above candidate request signal is used as the new target request signal for subsequent processing steps.

[0115] S204. If the processing priority of the candidate request signal is lower than or equal to the processing priority of the target request signal being processed, then it is confirmed that there is no target request signal in the steering style request signal.

[0116] If none of the newly received steering style request signals (i.e., the highest priority candidate request signal among these steering style request signals) has a higher processing priority than the target request signal that the domain controller is currently responding to, then the response to that target request signal will continue, and it will be assumed that there is no target request signal among the newly received steering style request signals that can be responded to.

[0117] S205, in response to the fact that there is no target request signal being processed in the domain controller's processing process, the candidate request signal is confirmed as the target request signal.

[0118] If there is no target request signal that the domain controller is responding to, the candidate request signal with the highest processing priority will be selected as the target request signal. The domain controller will respond to the target request signal and perform subsequent processing steps on the target request signal.

[0119] This application embodiment ensures that during the response period of a target request signal, other steering style request signals (including newly received steering style request signals) with lower processing priority than the target request signal will not be responded to. However, when a steering style request signal with higher processing priority is received, the currently responding target request signal is interrupted, and the higher-priority steering style request signal is responded to first, thereby ensuring a timely response to the high-priority steering style request.

[0120] Based on the above embodiments, such as Figure 3 As shown, step S201 above, "selecting the steering style request signal with the highest processing priority from the received steering style request signals as candidate request signals," includes the following steps:

[0121] S301, determine whether the number of received steering style request signals is greater than 1.

[0122] In some embodiments, steering style request signals received at the same time can be uniformly referred to as the "received steering style request signal" mentioned above. Alternatively, a time interval can be set as needed, and steering style request signals received within that time interval can be uniformly referred to as the "received steering style request signal" mentioned above. This application does not impose any limitations on this.

[0123] In this embodiment, the number of received steering style request signals is counted. It is then determined whether the value is greater than 1.

[0124] S302, in response to the number of steering style request signals being 1, the steering style request signal is determined as a candidate request signal.

[0125] If the number of received steering style request signals is 1, the priority filtering process is omitted, and the unique steering style request signal is used as the candidate request signal.

[0126] S303, in response to the number of steering style request signals being greater than 1, the steering style request signal with the highest processing priority is selected from the steering style request signals as a candidate request signal based on the processing priority of the steering style request signals.

[0127] When there are 2 or more steering style request signals received, the steering style request signal with the highest processing priority needs to be selected as the candidate request signal based on the processing priority of each steering style request signal.

[0128] In this embodiment of the application, the processing priority of the steering style request signal can be determined by the signal source priority and the steering style priority requested by the signal.

[0129] The signal source priority can be understood as the response priority of a steering style request signal sent by any sender in the domain controller.

[0130] The priority of the steering style request is the same as the priority of the steering style request signal.

[0131] Therefore, in this embodiment, the received steering style switching signals are further filtered based on the number of signals, reducing the pressure of processing priority filtering. Furthermore, when setting the processing priority of steering style request signals, the priority of the signal source and the priority of the steering style are fully considered, thereby prioritizing the processing of signals sent by a specific sender requesting a specific steering style. This facilitates setting different signal response priorities for different driving scenarios, enhancing the flexibility of signal processing.

[0132] In some embodiments, the signal source priority is: the priority of the steering style request signal sent by the driving assistance component based on intelligent decision is higher than the priority of the steering style request signal sent by the interaction component based on user operation;

[0133] The priority of steering style request signals sent by interactive components based on user operations is higher than the priority of steering style request signals triggered by driving mode switching.

[0134] Among them, the steering style request signal issued by the driving assistance component based on intelligent decision-making can be the steering style request signal issued by the ECU of the Advanced Driver Assistance System (ADAS), or in the case of autonomous driving or in the case where the vehicle's intelligent equipment has the main control of the vehicle, the steering style request signal is sent based on the signal collected by the sensor, processed by the algorithm, and sent through intelligent decision-making.

[0135] Furthermore, in practice, steering style switching or setting is often associated with driving mode switching. When the driving mode changes, a steering style request signal triggered by the driving mode switch will be sent to the domain controller. In some embodiments, the driving mode switch request signal can be directly used as the steering style request signal triggered by the driving mode switch in this application.

[0136] In addition, lanes can be associated with steering styles, such as associating a specific lane with a specific steering mode. In response to entering that specific lane, a steering style request signal is triggered to switch the steering style to the style corresponding to the specific steering mode associated with that lane.

[0137] In some embodiments, the steering style includes the steering style corresponding to a preset steering mode and the style corresponding to a custom steering assist percentage. The priority of the steering style requested by the signal is: the steering style corresponding to the custom steering assist percentage has a higher priority than the steering style corresponding to the preset steering mode.

[0138] In this embodiment of the application, the received steering style request signal can be divided into a steering mode switching request signal and a steering assist percentage adjustment request signal according to the steering style.

[0139] In addition, the received steering style request signals can be classified according to the signal source, i.e. the signal sending end, into steering style request signals issued by the ADAS system, steering style request signals issued by the central control system, and steering style request signals triggered by driving mode switching, etc.

[0140] In some embodiments, when a signal requesting a steering mode switch and a signal requesting the setting of a custom steering assist percentage value are received, the request to adjust the steering assist percentage is responded to first.

[0141] It should be noted that adjusting the steering style ultimately boils down to adjusting the steering assist or steering effort. Pre-set general steering modes, such as Sport mode and Relax mode, can be provided for users to choose from. Different steering modes will correspond to different steering assist and steering effort, resulting in different steering wheel feel, i.e., different steering styles. A custom mode can also be provided, allowing users to select their desired steering assist percentage. Again, different steering assist percentages will correspond to different steering wheel feel, i.e., different steering styles.

[0142] In some embodiments, the signal source priority is taken as the first priority, and the steering style priority is added on the basis of the first priority. Therefore, combining the signal source priority and the steering style priority, this application sets the following processing priority for steering style request signals:

[0143] The processing priority of steering percentage adjustment request signals issued by ADAS ECU > the processing priority of steering mode switching request signals issued by ADAS ECU > the processing priority of steering assist percentage adjustment request signals issued by central control > the processing priority of steering mode switching request signals issued by central control > the processing priority of steering assist percentage adjustment request signals triggered by driving mode switching > the priority of steering mode switching request signals triggered by driving mode switching.

[0144] Alternatively, the processing priority of the steering mode switching request signal issued by the ADAS ECU is greater than the processing priority of the steering assist percentage adjustment request signal issued by the central control unit, which is greater than the processing priority of the steering mode switching request signal issued by the central control unit, which is greater than the priority of the steering mode switching request signal triggered by the driving mode switch.

[0145] For example, such as Figure 4 As shown, after receiving the steering style request signal, it first determines whether there is a steering mode switching request signal issued by the ADAS ECU. If there is, it responds to the steering mode switching request signal issued by the ADAS ECU. During the continuous ADAS request, the steering mode switching request signal triggered by the driving mode switch, the steering mode switching request signal issued by the central control, and the steering assist percentage adjustment request signal are ignored.

[0146] If there is no steering mode switching request signal from the ADAS ECU, then determine whether there is a steering assist percentage adjustment request signal from the central control unit. If there is, respond to the steering assist percentage adjustment request signal from the central control unit. During the request response period, ignore the steering mode switching request signal triggered by driving mode switching and the steering mode switching request signal from the central control unit.

[0147] If there is no steering assist percentage adjustment request signal from the central control, then determine whether there is a steering mode switching request signal from the central control. If there is, respond to the steering mode switching request signal from the central control. During the request response period, ignore the steering mode switching request signal triggered by driving mode switching.

[0148] If there is no steering mode switching request signal from the central control, then respond to the steering mode switching request signal triggered by the driving mode switch.

[0149] After the driver assistance system is activated, primary control of the vehicle is transferred from the driver to the ADAS. Therefore, the embodiments of this application, through the above-described settings, ensure timely response to steering style request signals issued by the ADAS system. When the driver assistance system is not activated, user commands are given priority, and request signals triggered by other functions are processed with the lowest priority. This ensures timely response to the commands of the vehicle's primary controller, guarantees driving safety, and enhances the user experience.

[0150] Based on the above embodiments, the step S103 of "determining the validity of the target request signal" includes the following process:

[0151] Determine whether the vehicle's current steering style parameters are the same as the steering style parameters corresponding to the target request signal; if they are the same, the target request signal is invalid; if they are different, the target request signal is valid.

[0152] If the steering style parameters corresponding to the target request signal are the same as the vehicle's current steering style parameters, then there is no need to switch the steering style based on the target request signal. The target request signal is then deemed invalid.

[0153] This application embodiment reduces unnecessary processing steps, shortens the computational burden on the domain controller, and shortens the signal response time by judging the validity of the target request signal.

[0154] In some embodiments, the steering style parameter corresponding to the target request signal is used to set the steering style requested by the target request signal. The vehicle's current steering style parameter includes an identifier of the current steering mode and a value of the current steering assist percentage, while the steering style parameter corresponding to the target request signal includes either an identifier of the steering mode or a value of the steering assist percentage.

[0155] The above step of "determining whether the vehicle's current steering style parameters are the same as the steering style parameters corresponding to the target request signal" may further include the following two cases:

[0156] When the target request signal is a steering assist percentage adjustment request signal, determine whether the steering assist percentage value corresponding to the target request signal is the same as the current steering assist percentage value of the vehicle.

[0157] When the target request signal is a steering mode switching request signal, determine whether the steering mode identifier corresponding to the target request signal is the same as the identifier of the vehicle's current steering mode.

[0158] In this embodiment of the application, the target request signal may include the value of the requested steering assist percentage, or the identifier of the requested steering mode, or the identifier of the switched driving mode, and the steering style parameters corresponding to the target request signal are determined based on these parameter values.

[0159] This application embodiment compares the value of the steering assist percentage requested by the target request signal with the current steering style parameter of the same type, and compares the identifier of the steering mode requested by the target request signal with the current steering style parameter of the same type, thereby enhancing the accuracy and efficiency of the determination of the validity of the target request signal.

[0160] In some embodiments, before determining whether the vehicle's current steering style parameters are the same as the steering style parameters corresponding to the target request signal, the following process is also included:

[0161] When the target request signal is a steering style request signal triggered by driving mode switching, the driving mode after switching is determined based on the target request signal;

[0162] Based on the switched driving mode and the preset mapping relationship, the steering style parameters corresponding to the switched driving mode are determined and used as the steering style parameters corresponding to the target request signal. The preset mapping relationship is the correspondence between the driving mode and the steering style parameters.

[0163] In some embodiments, the steering style request signal triggered by driving mode switching can be a driving mode request signal, which includes the driving mode to be switched, i.e. the driving mode after switching.

[0164] In this application embodiment, based on the pre-stored correspondence between driving modes and steering styles, the steering style parameter corresponding to the switched driving mode is determined, and the steering style parameter is used as the steering style parameter corresponding to the target request signal.

[0165] The correspondence between driving mode and steering style parameters may include: the correspondence between driving mode and steering mode identifiers and / or the correspondence between driving mode and steering assist percentage value.

[0166] When the steering style request signal triggered by driving mode switching is a steering mode switching request signal, the steering mode corresponding to the switched driving mode is determined based on the correspondence between driving mode and steering mode, and then the steering mode identifier is determined.

[0167] When the steering style request signal triggered by driving mode switching is a steering assist percentage adjustment request signal, the steering assist percentage value corresponding to the switched driving mode is determined based on the correspondence between driving mode and steering assist percentage value.

[0168] Therefore, by pre-storing the correspondence between driving modes and steering style parameters, this embodiment of the application can directly switch the steering style associated with the driving mode based on the driving mode switching request signal. This enhances the diversity of steering style request signals that the domain controller can handle.

[0169] In some embodiments, the above-mentioned preset mapping relationship for different vehicle models may differ. Therefore, this application may also determine the preset mapping relationship for a specific vehicle model by setting a vehicle configuration code to select a specific vehicle model.

[0170] The target request signal can be a steering assist percentage adjustment request signal, a steering mode switching request signal, or a driving mode switching request signal; and the driving mode is only associated with the steering mode. For example,... Figure 5 As shown, it determines whether the target request signal is a steering assist percentage adjustment request signal. If so, it determines whether the requested steering assist percentage value is the same as the current steering assist percentage value. If they are the same, it sends the requested steering assist percentage value to the steering controller. If they are not the same, it ends the current process.

[0171] If the target request signal is not a steering assist percentage adjustment request signal, then determine whether the target request signal is a driving mode switching request signal. If so, determine the steering mode requested by the target request signal based on the driving mode and steering mode lookup table. Then determine whether the requested steering mode is the same as the current steering mode. If they are not the same, send the identifier of the requested steering mode to the steering controller. If they are the same, end the current process.

[0172] If the target request signal is not a driving mode switching request signal, it is determined whether the steering mode requested by the target request signal is the same as the current steering mode. If they are not the same, the identifier of the requested steering mode is sent to the steering controller. If they are the same, the current process ends.

[0173] Furthermore, in some embodiments, the steering style request signal triggered by driving mode switching may directly include the pre-determined steering style corresponding to the switched driving mode. To clearly illustrate the vehicle steering style request signal processing method proposed in this application, the following is a detailed explanation... Figure 6 Provide an overall process description. For example... Figure 6 As shown, the CCU of the domain controller determines the processing priority of the vehicle steering style request signal. At the same time, it determines whether the current driving state meets the steering style switching conditions based on the vehicle driving status signal. Based on the above processing priority judgment result and steering style switching condition judgment result, it determines whether to enable the validity judgment of the steering style request signal. After the validity judgment, the CCU sends the steering style parameters corresponding to the valid steering style request signal to the electronic power steering controller EPS. The ECU of the EPS sets the requested steering style according to the received steering style parameters.

[0174] In summary, the vehicle steering style request signal processing method provided in this application separates the steering style request signal processing function, which is strongly related to user experience and OEM requirements, into the CCU, while retaining the steering style switching execution function, whose execution requirements remain unchanged, in the EPS ECU. This approach facilitates OEMs in making logical modifications and calibrations based on user experience requirements, reducing the need for frequent software modifications, integrations, and verifications of component ECUs by component suppliers during development. This saves component development costs and time, and improves the OEM's integration and development capabilities and modification freedom. Furthermore, it reduces software changes to component ECUs, improving the applicability of the software platform.

[0175] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0176] Figure 7 This is a block diagram of a vehicle domain controller according to an exemplary embodiment of this application, such as... Figure 7 As shown, the domain controller includes: a signal priority judgment module 701, a condition judgment module 702, and a validity judgment module 703.

[0177] Signal priority determination module 701 receives steering style request signals and determines whether a target request signal exists in the steering style request signals; and

[0178] The condition judgment module 702 is used to acquire the current driving state signal and determine whether the current driving state meets the steering style switching conditions based on the current driving state signal; if not, the current processing process ends.

[0179] The validity judgment module 703 determines the validity of the target request signal if a target request signal exists and the current driving state meets the steering style switching conditions. It then sends the steering style parameters corresponding to the valid target request signal to the steering controller so that the steering controller can switch the vehicle steering style according to the steering style parameters.

[0180] In this embodiment of the application, the signal priority determination module is further used for:

[0181] From the received steering style request signals, select the steering style request signal with the highest processing priority as the candidate request signal;

[0182] In response to the presence of a target request signal being processed in the processing process of the domain controller, determine whether the processing priority of the candidate request signal is higher than the processing priority of the target request signal being processed.

[0183] If the processing priority of the candidate request signal is higher than the processing priority of the target request signal being processed, then the processing of the target request signal being processed will be terminated, and the candidate request signal will be confirmed as the new target request signal.

[0184] If the processing priority of the candidate request signal is lower than or equal to the processing priority of the target request signal being processed, then it is confirmed that there is no target request signal in the steering style request signal.

[0185] In response to the absence of a target request signal being processed in the domain controller's processing flow, the candidate request signal is recognized as the target request signal.

[0186] In this embodiment of the application, the signal priority determination module is further used for:

[0187] Determine if the number of received steering style request signals is greater than 1;

[0188] If the number of steering style request signals is 1, then the steering style request signal is determined as a candidate request signal;

[0189] If the number of steering style request signals is greater than 1, then based on the processing priority of the steering style request signals, the steering style request signal with the highest processing priority is selected as the candidate request signal.

[0190] Processing priority is determined by the priority of the signal source and the priority of the signal request's redirection style.

[0191] In this embodiment of the application, the priority of the signal source is as follows: the priority of the steering style request signal sent by the driving assistance component based on intelligent decision is higher than the priority of the steering style request signal sent by the interaction component based on user operation;

[0192] The priority of steering style request signals sent by interactive components based on user operations is higher than the priority of steering style request signals triggered by driving mode switching.

[0193] Steering styles include the steering style corresponding to the preset steering mode and the steering style corresponding to the custom steering assist percentage. The priority of the steering style is: the steering style corresponding to the custom steering assist percentage has a higher priority than the steering style corresponding to the preset steering mode.

[0194] In this embodiment of the application, the validity determination module is further used for:

[0195] Determine whether the vehicle's current steering style parameters are the same as the steering style parameters corresponding to the target request signal;

[0196] If they are the same, then the target request signal is invalid;

[0197] If they are different, then the target request signal is considered valid.

[0198] In this embodiment, the vehicle's current steering style parameters include an identifier of the current steering mode and a value of the current steering assist percentage. The steering style parameters corresponding to the target request signal include either an identifier of the steering mode or a value of the steering assist percentage. The validity determination module is further used for:

[0199] When the target request signal is a steering assist percentage adjustment request signal, determine whether the steering assist percentage value corresponding to the target request signal is the same as the current steering assist percentage value of the vehicle.

[0200] When the target request signal is a steering mode switching request signal, determine whether the steering mode identifier corresponding to the target request signal is the same as the identifier of the vehicle's current steering mode.

[0201] In this embodiment of the application, the signal validity determination module is further used for:

[0202] When the target request signal is a steering style request signal triggered by driving mode switching, the driving mode after switching is determined based on the target request signal;

[0203] Based on the switched driving mode and the preset mapping relationship, the steering style parameters corresponding to the switched driving mode are determined and used as the steering style parameters corresponding to the target request signal. The preset mapping relationship is the correspondence between the driving mode and the steering style parameters.

[0204] In summary, the domain controller of the vehicle proposed in this application processes the received steering style request signals: it filters out target request signals from the received steering style request signals, and simultaneously determines whether the steering style switching conditions are met. If the steering style switching conditions are met and a target request signal exists, it verifies the validity of the target request signal and sends the steering style parameters corresponding to the valid target request signal to the steering controller, so that the steering controller only needs to perform steering style switching according to the received steering style parameters. This application sets the personalization-related processing flow in the steering style switching function in the domain controller, so that OEMs can independently and flexibly update the relevant processing logic in the domain controller, enhancing the OEMs' development freedom for the steering style switching function and saving development time and costs.

[0205] Figure 8 This is a block diagram of a vehicle steering controller according to an exemplary embodiment of this application, such as... Figure 8 As shown, the steering controller includes an electronic processing unit 801.

[0206] The electronic processing unit 801 is used to receive steering style parameters sent by the domain controller and switch the vehicle steering style according to the steering style parameters.

[0207] In summary, the steering controller proposed in this application only needs to receive the steering style parameters obtained after the domain controller processes the steering style request signal, and then perform steering style switching according to the received steering style parameters. When further development or updates to the steering style are required, such as adding new steering styles or associating steering styles with other personalized functions, vehicle manufacturers can independently and flexibly develop new processing logic or update the relevant processing logic in the domain controller without requiring component suppliers to improve the steering controller's ECU, thus reducing software changes to the controller and improving its applicability.

[0208] Figure 9 This is a block diagram of a vehicle steering style switching system according to an exemplary embodiment of the present application. The system 900 includes the vehicle domain controller 700 and the vehicle steering controller 800 of the above embodiment.

[0209] Domain controller 700 is communicatively connected to steering controller 800.

[0210] In summary, the steering style switching system proposed in this application sets the processing of steering style request signals in the domain controller. The domain controller processes the received steering style request signals as follows: it filters out target request signals from the received signals and determines whether the current driving state meets the steering style switching conditions. If the conditions are met and a target request signal exists, it verifies the validity of the target request signal and sends the steering style parameters corresponding to the valid target request signal to the steering controller. This allows the steering controller to perform steering style switching simply based on the received steering style parameters. This application processes the steering style request signals in the domain controller to determine the steering style parameters to be output to the steering controller. When further development or updates to the steering style are needed, such as adding new steering styles or associating steering styles with other personalized functions, OEMs can independently and flexibly develop new processing logic or update the relevant processing logic in the domain controller without requiring component suppliers to modify the steering controller's ECU. This enhances the OEM's freedom in developing steering style setting functions and saves development time and costs. This application reduces software changes to component ECUs, increasing their applicability. Furthermore, during the processing of steering style request signals, constraints on steering style switching conditions ensure the safety of steering style switching. Additionally, this application can simultaneously handle steering style request signals from multiple transmitters, filtering out the target request signal, thereby enabling vehicle-wide processing of steering style request signals.

[0211] To implement the above embodiments, this application also proposes a vehicle 1000, which includes the steering style switching system 900 of the vehicle described in the above embodiments.

[0212] In summary, the vehicle proposed in this application processes the received steering style request signal in the domain controller as follows: It filters out the target request signal from the received steering style request signals and determines whether the current driving state meets the steering style switching conditions. If the steering style switching conditions are met and a target request signal exists, it verifies the validity of the target request signal and sends the steering style parameters corresponding to the valid target request signal to the steering controller. This allows the steering controller to perform steering style switching simply based on the received steering style parameters. This application processes the steering style request signal in the domain controller to determine the steering style parameters to be output to the steering controller. When further development or updates to the steering style are needed, such as adding new steering styles or associating steering styles with other personalized functions, OEMs can independently and flexibly develop new processing logic or update the relevant processing logic in the domain controller without requiring component suppliers to improve the steering controller's ECU. This enhances the OEM's freedom in developing steering style setting functions and saves development time and costs. It also reduces software changes to component ECUs, increasing their applicability. Furthermore, the processing of the steering style request signal ensures the safety of steering style switching through constraints on the steering style switching conditions. Furthermore, this application can simultaneously handle steering style request signals sent by multiple transmitters, and filter out the target request signal from them, thereby enabling the processing of steering style request signals without being directed to the entire vehicle.
