[0002] Currently, the personalized settings of vehicles have added custom settings such as power mode switching, steering mode switching, brake pedal feel switching, and ambient light switching. Among them, the most personalized one is the steering mode switching because the steering feel of the steering wheel is the most direct bridge for communication between people and vehicles, and the steering feel has particularity, which is mainly manifested in two aspects: 1. For the same vehicle, different people have different requirements for the steering feel; 2. For the same person, there are different requirements for the steering feel of different vehicles. Currently, the main way to adjust the steering feel mode of a vehicle is through the central control screen, but this method has two major drawbacks: 1. When the vehicle is driving, adjusting the steering mode on the central control screen poses a safety hazard; 2. Generally, the steering mode is located at the 2-3rd layer position of the main control interface of the central control screen, which is difficult to find.

[0070] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The embodiments described by referring to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as limiting the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0071] Figure 1 is a flowchart of a method for adjusting a steering mode of a vehicle shown according to an exemplary embodiment of the present application. As Figure 1 shown, the method for adjusting the steering mode of the vehicle includes the following steps:

[0072] S101, in response to obtaining a steering mode adjustment signal, obtain the current gear signal.

[0073] In the embodiment of the present application, when a steering mode adjustment signal is obtained, the current gear signal is obtained.

[0074] The steering mode adjustment signal is used to request a steering mode adjustment and set a new steering mode. In some embodiments, the steering mode adjustment signal can be generated based on the user's manipulation of the steering mode adjustment structure in the mechanical column shifter assembly. The mechanical column shifter assembly may include, but is not limited to, a steering mode adjustment structure and a gear shift structure.

[0075] For example, the user adjusts the current steering mode by manipulating the manipulation structure in the mechanical column shifter assembly, such as a lever. The current state of the manipulation structure can be collected by a sensor to obtain the steering mode requested by the user, and the collected signal is used as the steering mode adjustment signal.

[0076] In practice, the mechanical column shifter is arranged behind the steering wheel and can be a lever that can be moved up and down. Generally, two levers are arranged behind the steering wheel of a vehicle, one on each side. One is used to control the lights and the other is used to achieve gear shifting.

[0077] The manipulation structure of the mechanical column shifter assembly in the present application can be used for gear shifting and can also be used to adjust the steering mode. As Figure 2 shown, the mechanical column shifter assembly includes a manipulation structure 2. The manipulation structure can be divided into a steering mode switching structure (i.e., the forward manipulation structure) and a gear shift structure (i.e., the manipulation structure that can be moved up and down). By manipulating this manipulation structure, the steering mode switching and gear shifting can be achieved. Among them, the "forward" direction is the direction close to the steering wheel, or the direction that shortens the gap with the steering wheel.

[0078] In the embodiment of the present application, when the driver makes a steering mode adjustment manipulation on the mechanical column shifter, Figure 2 the sensor 1 arranged on the mechanical column shifter assembly collects the steering mode adjustment signal. The steering controller will obtain the steering mode adjustment signal. When the steering mode adjustment signal is obtained, it can be known that the driver requests a steering mode adjustment. At this time, the current gear signal is obtained.

[0079] S102, determine whether the current working condition of the vehicle meets the requirements of the steering mode adjustment condition.

[0080] In the embodiment of the present application, while obtaining the current gear signal, it can be verified whether the steering mode adjustment environment meets the requirements, that is, whether the current working condition of the vehicle meets the requirements of the steering mode adjustment condition. Among them, the steering mode adjustment condition can be a constraint condition to ensure the safety of the vehicle during the steering mode adjustment process.

[0081] The current operating condition of the vehicle can be obtained by acquiring the driving state signal, driving status signal, etc. of the vehicle. The types of these signals can be determined according to the steering mode adjustment conditions, which are not limited in this application.

[0082] For example, the steering mode adjustment condition can be: current vehicle speed ≤ 120 km / h, steering wheel torque ≤ 3 N / s, and steering wheel angular velocity ≤ 360° / s.

[0083] Collect the current vehicle speed signal, steering wheel torque signal, and steering wheel angular speed signal, and determine whether these signals under the current operating condition meet the requirements of the steering mode adjustment condition. If they are met, it is considered that the steering mode can be safely adjusted under the current operating condition, set a new steering mode, and the subsequent processing process can continue. If not, adjusting the steering mode under the current operating condition will pose a potential hazard to driving. To ensure driving safety, end the current steering mode adjustment process.

[0084] S103, if the current operating condition of the vehicle meets the requirements of the steering mode adjustment condition, adjust the steering mode corresponding to the current gear according to the current gear signal and the steering mode adjustment signal.

[0085] In some embodiments, if the current operating condition of the vehicle meets the requirements of the steering mode adjustment condition, determine the steering mode requested by the driver according to the steering mode adjustment signal, and adjust the steering mode corresponding to the current gear according to the steering mode requested by the driver.

[0086] In some embodiments, after determining the current gear based on the current gear signal, the steering mode currently corresponding to this gear can also be determined, and the steering mode corresponding to this gear can be adjusted according to the steering mode currently corresponding to this gear and the steering mode requested by the driver.

[0087] In some embodiments, after obtaining the current gear, one or more steering modes associated with this gear can also be determined. The steering mode associated with this gear can be understood as the steering mode that is allowed to be set when the vehicle processes this gear; based on one or more steering modes associated with this gear and the steering mode requested by the driver, adjust the steering mode corresponding to this gear.

[0088] In summary, the steering mode adjustment method of the vehicle in this application obtains the current gear signal after obtaining the steering mode adjustment signal. When the current working condition of the vehicle meets the steering mode adjustment condition, the steering mode corresponding to the current gear is adjusted according to the steering mode adjustment signal and the current gear signal. This application associates the gear with the steering mode, facilitating the user to set the corresponding steering mode for different gears. Among them, the steering mode adjustment signal is generated based on the state of the operating structure for adjusting the steering mode in the mechanical shift-by-wire assembly. This application integrates the steering mode adjustment and gear shifting in the mechanical shift-by-wire assembly, realizing the steering mode adjustment conveniently, reducing the safety hazards brought by the steering mode adjustment, and enhancing the user experience.

[0089] Based on the above embodiments, as Figure 3 shown, before the step S103 in the embodiment of this application, "adjust the steering mode corresponding to the current gear according to the current gear signal and the steering mode adjustment signal", the following steps are further included:

[0090] S301, determine whether there is abnormal jitter in the steering mode adjustment signal.

[0091] In the embodiment of this application, after the steering mode adjustment condition is satisfied, the jitter judgment processing function of the activation signal is activated.

[0092] In some embodiments, it can be determined whether the number of signal changes of the steering mode adjustment signal exceeds a preset threshold within a preset time interval. If it exceeds the preset threshold, it is considered that there is abnormal jitter in the steering mode adjustment signal. If it does not exceed the preset threshold, it is considered that there is no abnormal jitter in the steering mode adjustment signal.

[0093] For example, set the jitter signal as a signal with the number of signal changes ≥ 9 within 500 ms. The jitter judgment processing is mainly performed through the time and sequence of the steering mode switching function program. When the vehicle starts, the time starts to be calculated and executed (since it takes 10 ms for one program run, and the set timing type is uint16 with a data length of 65536, so when the timing ≥ 60000, subtract 50000 for data anti-overflow processing). When there is a demand for the steering mode adjustment signal (i.e., ReqFlag = 1), add this time value to the new sequence, and at the same time, the effective length of the new sequence +1. If the effective length is less than the preset jitter threshold 9, it is considered that the signal has no abnormal jitter response.

[0094] S302, if there is no abnormal jitter, confirm that the steering mode adjustment signal is normal, and execute the step of adjusting the steering mode corresponding to the current gear according to the current gear signal and the steering mode adjustment signal.

[0095] If there is no abnormal jitter in the steering mode adjustment signal, continue to execute the subsequent process for this steering mode adjustment signal.

[0096] In S303, if there is abnormal jitter, confirm that the steering mode adjustment signal is abnormal and end the current process.

[0097] If there is abnormal jitter in the steering mode adjustment signal, it can be considered that the steering mode adjustment signal is a signal triggered abnormally. For example, a signal triggered by a user accidentally touching the joystick for steering mode adjustment. Then, do not respond to this steering mode adjustment signal and end the current process.

[0098] In the embodiment of the present application, by performing jitter judgment processing on the steering mode adjustment signal, abnormal steering mode adjustment signals are screened to avoid abnormal signals occupying the processing process, so as to respond to normal steering mode adjustment signals in a timely manner.

[0099] Based on the above embodiment, as Figure 4 shown, in the above step S103, "adjust the steering mode corresponding to the current gear according to the current gear signal and the steering mode adjustment signal" includes the following steps:

[0100] S401, obtain the mode value of the steering mode corresponding to the current gear.

[0101] Obtain the mode value of the steering mode currently corresponding to the current gear, where the mode value can be the serial number or character corresponding to each steering mode. The steering controller can set the specific steering mode according to this mode value, and this mode value can also be displayed on the instrument panel to show the user the current steering mode.

[0102] S402, determine the mode value of the target steering mode according to the steering mode adjustment signal.

[0103] In some embodiments, the steering mode adjustment signal may include the mode value of the target steering mode. In this case, the mode value can be directly obtained from the steering mode adjustment signal.

[0104] In some embodiments, when the sensor collects the structural state of the part related to the steering mode adjustment in the operating structure, the structural state information can be obtained by obtaining the state value of this structural state. For example, when the lever is pushed forward once, the state value of the current state of the lever, and different state values correspond to different steering modes; write this state value into the steering mode adjustment signal. The present application determines the steering mode requested by the driver based on this state value, and further the mode value of this steering mode can be determined.

[0105] S403, if the mode value of the steering mode corresponding to the current gear is different from the mode value of the target steering mode, adjust the steering mode corresponding to the current gear according to the mode value of the target steering mode.

[0106] In the embodiments of the present application, by comparing the mode value of the steering mode corresponding to the current gear with the mode value of the target steering mode requested by the steering mode adjustment signal, the steering mode of the vehicle in the current gear is determined, and whether it is the same as the target steering mode requested by the steering mode adjustment signal, so as to determine whether the received steering mode adjustment signal is a valid signal and whether it is necessary to adjust the steering mode according to the steering mode adjustment signal.

[0107] The present application determines whether the steering mode adjustment signal is valid by comparing the mode value of the current steering mode with the mode value of the target requested mode, and further determines whether it is necessary to continue the steering mode adjustment process. In this way, invalid signals are screened to improve the response time of the steering mode adjustment request.

[0108] In practice, the driving gears of the vehicle can include the forward gear (D gear), the reverse gear (R gear), the parking gear (P gear), and the neutral gear (N gear).

[0109] After obtaining the steering mode adjustment signal in a certain gear in the present application, the current steering mode of this gear is adjusted. In this way, a steering mode associated with each gear can be set, and by recording the mode value of the steering mode set in this gear, when switching to this gear next time, the corresponding steering mode can be directly activated.

[0110] Based on the above embodiments, if the current gear is the parking gear, after adjusting the steering mode corresponding to the parking gear according to the steering mode adjustment signal, the steering modes corresponding to other gears except the parking gear are also synchronized to the steering mode after the parking gear is switched, so as to maintain the steering feel of the steering wheel and ensure driving safety after the vehicle starts.

[0111] In some embodiments, the steering mode can include predefined steering modes such as the light mode, the comfort mode, the sport mode, etc. The steering mode can also include a custom steering hand force ratio mode, that is, the user can customize the steering hand force ratio to adjust the steering assist or the steering hand force.

[0112] The steering feel of the steering wheel is the most direct bridge for communication between people and the vehicle, and the steering feel has particularity, which is mainly manifested in two aspects: 1. For the same vehicle, different people have different steering feel requirements; 2. For the same person, there are different steering feel requirements for different vehicles.

[0113] Different steering modes correspond to different steering feels, and different steering feels are achieved by adjusting the steering assist or adjusting the steering hand force ratio through an assist steering controller (such as an electronic power steering controller EPS).

[0114] Therefore, the adjustment of the steering mode can be regarded as the adjustment of steering assist or steering hand force to a certain extent. The predefined steering modes are general modes provided for users to directly select. Different steering modes correspond to different steering assist values, while the custom steering hand force ratio mode allows users to freely set the required steering hand force ratio to adjust the steering feel.

[0115] Based on the above embodiments, as Figure 5 shown, in the above step S402, "determining the mode value of the target steering mode according to the steering mode adjustment signal" may include the following steps:

[0116] S501, based on the steering mode adjustment signal, determine the mode identifier corresponding to the steering mode adjustment signal.

[0117] In this application, each steering mode corresponds to a mode identifier, which is used to mark the mode, such as the easy mode, the custom steering hand force ratio mode, etc. The identifier can be a number or a character. The mode identifier can also be displayed on the instrument panel or the center control screen to show the driver the current steering mode adopted by the vehicle.

[0118] In some embodiments, the mode value of the predefined steering mode is the mode identifier corresponding to the predefined steering mode, and the mode value corresponding to the custom steering hand force ratio mode is the specific hand force ratio value.

[0119] It should be noted that the mode identifier of the predefined steering mode can be used as the mode value, both of which can represent the corresponding mode; while the mode identifier of the custom steering hand force ratio mode is used to represent the mode, and the mode value is used to represent the specific steering hand force ratio value in this mode.

[0120] Determine the mode identifier corresponding to the steering mode adjustment signal according to the steering mode adjustment signal. In some embodiments, this mode identifier can be written into the steering mode adjustment signal.

[0121] S502, in response to the steering mode corresponding to the mode identifier being the custom steering hand force ratio mode, obtain the target steering hand force ratio value customized by the user, and determine the target steering hand force ratio value as the mode value of the target steering mode.

[0122] Based on the mode identifier determined from the steering mode adjustment signal, when the steering mode corresponding to this mode identifier is the custom steering hand force ratio mode, it is necessary to additionally obtain the target steering hand force ratio value customized by the user.

[0123] The embodiments of this application set up a variety of selectable steering modes. On the basis of the predefined steering modes, a customizable steering hand force ratio mode is added, so that users can flexibly adjust the steering hand force ratio according to their needs, enhancing the diversity of steering styles, the selectivity of steering modes, and the user experience.

[0124] Based on the above embodiments, for the custom steering hand force ratio mode, as Figure 6 shown, in the above step S502, "obtaining the target hand force ratio value customized by the user" includes the following steps:

[0125] S601, obtaining the hand force ratio adjustment reference value set by the user through a preset adjustment component.

[0126] In the embodiments of the present application, the user can flexibly set the reference value for hand force ratio adjustment through a preset adjustment component. The hand force ratio adjustment reference value can be understood as the reference value set by the user by operating the preset adjustment component.

[0127] For example, by setting a roller on the steering wheel and rotating the roller to set the reference value for hand force ratio adjustment, the reference value is the percentage corresponding to the rotation angle of the roller. The specific value is not limited in the present application.

[0128] In addition, the preset adjustment component can also be a button or a slider, etc., which is not limited in the present application.

[0129] S602, determining the target hand force ratio value according to the hand force ratio adjustment reference value and the custom hand force ratio curve, where the custom hand force ratio curve is the relationship curve between the hand force ratio adjustment reference value and the hand force ratio value.

[0130] For the preset adjustment component, set its corresponding custom hand force ratio curve, which is the relationship curve between the hand force ratio reference value and the hand force ratio value.

[0131] For example, the user can rotate the roller to set the adjustment degree, take the ratio of the rotation angle of the operated roller to the total rotatable angle range of the roller as the percentage corresponding to the operated roller, and determine the hand force ratio value corresponding to the percentage based on this percentage and the custom hand force ratio curve. The value range of the hand force ratio value can be 0 to 100%, so as to achieve infinite adjustment of the steering hand force.

[0132] The present application facilitates the user to flexibly adjust the hand force ratio by setting an easy-to-operate preset adjustment component in the vehicle. When it is necessary to change the adjustment granularity of the preset adjustment component, only need to reset the hand force ratio curve, which has strong applicability and flexibility in adjusting the steering style.

[0133] In the embodiments of the present application, the adjustment rules for different gear steering modes can be preset in advance: for example, when the vehicle is in neutral gear, no steering mode adjustment function is provided to ensure the safety of vehicle driving:

[0134] Before adjusting the steering mode corresponding to the current gear according to the current gear signal and the steering mode adjustment signal, first determine whether the current gear is in neutral. If it is in neutral, end the current process. If it is not in neutral, continue to execute the step of adjusting the steering mode corresponding to the current gear according to the current gear signal and the steering mode adjustment signal.

[0135] For example: when the vehicle is in the N gear and the driver performs a steering mode adjustment operation on the shift lever, the ECU obtains the N gear signal, does not activate the steering mode adjustment function, and displays "The current gear cannot adjust the steering mode. Please switch to D / R / P gear" on the instrument panel or the center console screen.

[0136] In addition, when the vehicle is in the P gear and the driver performs a steering mode adjustment operation on the shift lever, the ECU obtains the P gear signal and activates the jitter judgment and processing function of the signal. If it is confirmed that there is no abnormal jitter response in the signal, the steering mode adjustment function is activated.
