[0070] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments of the present application. The embodiments described by reference to the drawings are exemplary and are intended to explain the present application, but cannot be understood as a limitation of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0071] Figure 1 is a flow chart of a steering mode adjustment method of a vehicle according to an example embodiment of the present application, as shown in Figure 1 the steering mode adjustment method of the vehicle comprises the following steps:

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

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

[0074] The steering mode adjustment signal is used to request 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 gear holding assembly. The mechanical gear holding assembly can include, but is not limited to, the steering mode adjustment structure and the gear shifting structure.

[0075] For example, the user adjusts the current steering mode by manipulating the manipulation structure, such as a lever, in the mechanical gear holding assembly. 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 gear holding assembly 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, one on the left and one on the right, one for controlling the lights and one for implementing gear shifting.

[0077] The manipulation structure of the mechanical gear holding assembly of the present application can be used for gear shifting and also for adjusting the steering mode. As shown in Figure 2 The manipulation structure 2 is included in the mechanical gear holding assembly, which can be divided into a steering mode shifting structure (i.e., a forward manipulation structure) and a gear shifting structure (i.e., a manipulation structure that can be moved up and down), and the steering mode shifting and gear shifting can be achieved by manipulating the manipulation structure. The "forward" direction is the direction close to the steering wheel, or the direction to shorten the gap between the steering wheel.

[0078] In the embodiments of the present application, when the driver manipulates the mechanical gear holding assembly for steering mode adjustment, Figure 2 The sensor 1 arranged on the mechanical gear holding assembly in the mechanical gear holding assembly collects the steering mode adjustment signal, and 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 to adjust the steering mode, and at this time the current gear signal is obtained.

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

[0080] In the embodiments of the present application, while obtaining the current gear signal, it can be verified whether the steering mode adjustment environment meets the requirement, i.e., whether the current working condition of the vehicle meets the steering mode adjustment condition requirement. 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 working condition of the vehicle can be obtained by obtaining driving state signals, driving state signals, etc. of the vehicle. The types of these signals can be determined according to the steering mode adjustment condition, which is not limited in the present application.

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

[0083] The current vehicle speed signal, steering wheel torque signal and steering wheel angle speed signal are collected to determine whether these signals meet the requirements of the steering mode adjustment condition under the current working condition. If they meet the requirements, it is considered that the steering mode adjustment can be safely performed under the current working condition, and a new steering mode is set, and the subsequent processing process can continue. If they do not meet the requirements, the steering mode adjustment under the current working condition will cause a driving hazard. In order to ensure driving safety, the current steering mode adjustment process is ended.

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

[0085] In some embodiments, if the current working condition of the vehicle meets the requirements of the steering mode adjustment condition, the steering mode requested by the driver is determined according to the steering mode adjustment signal, and the steering mode corresponding to the current gear is adjusted 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 the gear can also be determined, and the steering mode corresponding to the gear is adjusted according to the steering mode currently corresponding to the 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 the gear can also be determined. The steering mode associated with the gear can be understood as the steering mode allowed to be set when the vehicle processes the gear. The steering mode corresponding to the gear is adjusted based on the one or more steering modes associated with the gear and the steering mode requested by the driver.

[0088] In summary, the steering mode adjustment method of the vehicle in the application obtains the current gear signal after obtaining the steering mode adjustment signal. In the case that 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. The application associates the gear with the steering mode, which facilitates the user to set the corresponding steering mode for different gears. The steering mode adjustment signal is generated based on the state of the steering mode adjustment structure in the mechanical gear assembly. The application integrates the steering mode adjustment and the gear switching in the mechanical gear assembly, which conveniently realizes the steering mode adjustment, reduces the safety hazards caused by the steering mode adjustment, and enhances the user experience.

[0089] On the basis of the above-mentioned embodiments, as shown in Figure 3 Before the step S103 of adjusting the steering mode corresponding to the current gear according to the current gear signal and the steering mode adjustment signal, the embodiment of the application further includes the following steps:

[0090] S301, determining whether the steering mode adjustment signal has abnormal jitter.

[0091] The embodiment of the application activates the jitter determination and processing function of the signal after the steering mode adjustment condition is met.

[0092] In some embodiments, whether the number of signal changes of the steering mode adjustment signal within a preset time interval exceeds a preset threshold value can be determined. If the number of signal changes exceeds the preset threshold value, it is considered that the steering mode adjustment signal has abnormal jitter. If the number of signal changes does not exceed the preset threshold value, it is considered that the steering mode adjustment signal does not have abnormal jitter.

[0093] For example, the jitter signal is set to a signal with a signal change number ≥ 9 within 500 ms. The jitter determination and processing are mainly performed by the time and sequence of the steering mode switching function program. When the vehicle is started, the time starts to be calculated and executed (since the time sequence of running a program is 10 ms, and the type of set time sequence is uint16, the data length is 65536, so when the time sequence ≥ 60000, 50000 is subtracted for data overflow processing). When there is a steering mode adjustment signal requirement (i.e. ReqFlag = 1), the time value is added to the new sequence, and the effective length of the new sequence is increased by 1. If the effective length is less than the preset jitter threshold value 9, it is considered that the signal has no abnormal jitter response.

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

[0095] If the steering mode adjustment signal has no abnormal jitter, the subsequent process is continued for the steering mode adjustment signal.

[0096] S303, if there is abnormal jitter, it is confirmed that the steering mode adjustment signal is abnormal, and the current process is ended.

[0097] If the steering mode adjustment signal has abnormal jitter, it can be considered that the steering mode adjustment signal is an abnormally triggered signal, for example, a signal triggered by the user accidentally touching the steering mode adjustment lever. The steering mode adjustment signal is not responded to, and the current process is ended.

[0098] In the embodiments of the application, abnormal steering mode adjustment signals are screened by jitter judgment and processing of the steering mode adjustment signal, so as to avoid abnormal signals occupying the processing process, so as to respond to normal steering mode adjustment signals in time.

[0099] On the basis of the above-mentioned embodiments, as shown in Figure 4 The above-mentioned step S103 “adjusting 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, obtaining the mode value of the steering mode corresponding to the current gear.

[0101] The mode value of the steering mode corresponding to the current gear is obtained, wherein the mode value can be a serial number or a character corresponding to each steering mode. The steering controller can set a specific steering mode according to the mode value, and the mode value can also be displayed on the instrument screen to temporarily display the current steering mode to the user.

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

[0103] In some embodiments, the mode value of the target steering mode can be included in the steering mode adjustment signal, in which case the mode value can be directly obtained from the steering mode adjustment signal.

[0104] In some embodiments, when the sensor collects the structure state of the steering mode adjustment part of the steering structure, the structure state information can be obtained by obtaining the state value of the structure state, for example, the state value of the current state of the lever is moved forward once, and different state values correspond to different steering modes. The state value is written in the steering mode adjustment signal. The application determines the steering mode requested by the driver based on the state value, and further determines the mode value of the steering mode.

[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, the steering mode corresponding to the current gear is adjusted according to the mode value of the target steering mode.

[0106] In the embodiments of the present application, whether the steering mode of the vehicle at the current gear is the same as the target steering mode requested by the steering mode adjustment signal is determined by comparing the mode value of the current steering mode corresponding to the current gear with the mode value of 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 the steering mode adjustment needs to be performed 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 then determines whether the steering mode adjustment process needs to be continued. In this way, invalid signals are screened out, and the response time of the steering mode adjustment request is improved.

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

[0109] The present application adjusts the current steering mode for a gear after obtaining the steering mode adjustment signal for the gear. In this way, the steering mode associated with each gear can be set, and the mode value of the steering mode set at the gear can be recorded to directly start the corresponding steering mode when switching to the gear next time.

[0110] On the basis of 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 switched to the steering mode after the parking gear, so as to maintain the steering feel of the steering wheel after the vehicle starts and ensure driving safety.

[0111] In some embodiments, the steering mode can include predefined steering modes such as light mode, comfortable mode, sport mode, etc. The steering mode can also include a self-defined steering effort ratio mode, i.e., the user can self-define the steering effort ratio to adjust the steering assist or steering effort.

[0112] The steering feel of the steering wheel is the most direct bridge for people to communicate with the vehicle, and the steering feel is specific, mainly in two aspects: 1. For the same vehicle, different people have different steering feel needs; 2. For the same person, there are different steering feel needs 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 effort ratio through the power steering controller (such as the electronic power steering controller EPS).

[0114] Therefore, the adjustment of the steering mode can be regarded as adjustment of steering assistance or steering effort to some extent. The predefined steering mode is a general mode directly selected by the user, different steering modes correspond to different steering assistance values, and the custom steering effort ratio mode allows the user to freely set the required steering effort ratio value to adjust the steering feel.

[0115] On the basis of the above embodiments, as shown in Figure 5 The step S402 of determining the mode value of the target steering mode according to the steering mode adjustment signal can include the following steps:

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

[0117] Each steering mode in the present application corresponds to a mode identifier, which is used to mark the mode, such as the easy mode, the custom steering effort ratio mode, etc. The identifier can be a number or a character. The mode identifier can also be displayed on the instrument screen or the central 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 effort ratio mode is the specific effort ratio value.

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

[0120] According to the steering mode adjustment signal, the mode identifier corresponding to the steering mode adjustment signal is determined, and in some embodiments, the 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 effort ratio mode, obtaining the target steering effort ratio value customized by the user, and determining the target steering effort 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 the mode identifier is the custom steering effort ratio mode, the target steering effort ratio value customized by the user needs to be obtained additionally.

[0123] The embodiments of the present application provide a plurality of selectable steering modes. On the basis of the predefined steering mode, the custom steering effort ratio mode that can be flexibly set is added to allow the user to flexibly adjust the steering effort ratio according to the needs, thereby enhancing the diversity of steering style, the selectability of steering mode, and the user experience.

[0124] On the basis of the above-mentioned embodiments, for the custom steering hand force ratio mode, as shown in the figure, the step S502 of "obtaining the target hand force ratio value customized by the user" comprises the following steps: Figure 6

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

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

[0127] For example, by setting a scroll wheel on the steering wheel, the reference value of the hand force ratio adjustment is set by rotating the scroll wheel. The reference value is the percentage corresponding to the rotation angle of the scroll wheel, and 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, 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, the custom hand force ratio curve being a relationship curve between the hand force ratio adjustment reference value and the hand force ratio value.

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

[0131] For example, the user can set the adjustment degree by rotating the scroll wheel, and take the ratio of the angle of the scroll wheel operation to the total rotatable angle range of the scroll wheel as the percentage corresponding to the operation of the scroll wheel. Based on the percentage and the custom hand force ratio curve, the hand force ratio value corresponding to the percentage is determined. The hand force ratio value can be in the range of 0-100%, so as to realize the infinite adjustment of the steering hand force.

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

[0133] In the embodiments of the present application, the steering mode adjustment rules of different gears can be preset: for example, when the vehicle is in neutral, the steering mode adjustment function is not 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, it is judged whether the current gear is neutral, if yes, the current process is ended, if not, the step of adjusting the steering mode corresponding to the current gear according to the current gear signal and the steering mode adjustment signal is continued.

[0135] For example, when the gear of the vehicle is in N gear, the driver performs steering mode adjustment operation on the gear lever, the ECU acquires the N gear signal, the steering mode adjustment function is not activated, and the display of the instrument screen or the central control screen displays "the current gear cannot adjust the steering mode, please switch to D / R / P gear"
