[0035] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0036] In the related art, the brake pedal feeling has the following technical defects:

[0037] 1) The single and fixed brake pedal feeling style can only match the driving habits of a part of users, and cannot meet the driving comfort needs of other users.

[0038] 2) If the vehicle brake pedal feeling style cannot match the driving habits of the user, it is difficult for the user to control the vehicle to achieve the user's own deceleration expectation, which is easy to cause user complaints.

[0039] 3) If the user cannot adapt to the vehicle brake pedal feeling, the vehicle cannot be effectively and accurately controlled to decelerate, which poses a driving safety risk.

[0040] In order to solve the problems in the related art that the brake pedal feeling style is limited and fixed after calibration, cannot meet the user's driving needs, and is easy to cause driving safety risks, the present application proposes a control method for unlimited brake pedal feeling. Compared with the brake pedal feeling technology in the related art, the present application has the following advantages:

[0041] 1) Equipped with a physical or virtual adjustment button, the brake sensitivity of the vehicle can be infinitely adjusted in numerical value.

[0042] 2) The brake pedal feeling can be automatically matched according to the user's settings, and there are infinitely many brake pedal feeling styles in numerical value.

[0043] 3) The present application can keep the EHB hardware unchanged, the vehicle single vehicle cost and the research and development cost unchanged, and achieve unlimited brake pedal feeling style through software control, which can meet the driving habits of almost all users, improve the driving comfort, and reduce user complaints and after-sales cost.

[0044] 4) It has the advantages of low cost, simple calibration and short development cycle, and can be widely applied to vehicles equipped with EHB.

[0045] The control method, device, vehicle, medium and product for unlimited brake pedal feeling of the embodiments of the present application are described below with reference to the drawings.

[0046] Specifically, Figure 1 A flowchart of a control method for unlimited brake pedal feeling provided by the embodiments of the present application is shown in FIG. 1. As shown in FIG. 1, the control method for unlimited brake pedal feeling includes the following steps: Figure 1

[0047] ​In step S101, a current adjustment value of an adjustment button is acquired, the adjustment button allowing being adjusted to an arbitrary adjustment value.

[0048] The adjustment button includes a physical button and / or a virtual button, and an adjustment value is generated when the physical button and / or the virtual button is operated by a user.

[0049] It can be understood that the embodiments of the present application can adjust the adjustment button to an arbitrary value through operation of a physical or virtual adjustment button, and an adjustment value for control is generated after operation. The method is flexible in operation mode and can meet the use habits of different users.

[0050] Specifically, a user can adjust the pedal feeling without limitation through physical key feeling (physical button) or screen touch (virtual adjustment button). When a user operates a virtual adjustment button, such as an adjustment button on a multimedia large screen, a "brake sensitivity adjustment bar" is displayed on a vehicle-mounted screen, and a specific numerical range, for example, 0.5-1.5, corresponds to the middle. The user only needs to slide the finger on the adjustment bar, and the position where the slider stops will correspond to a numerical value, such as slowly sliding from 0.5 at the left end to 0.7, or directly dragging to 1.2, 1.4, etc. Each subtle sliding will generate a corresponding adjustment value in real time. When a user operates a physical adjustment button, such as a rotating button with scales, the numerical interval is marked on the rotating knob, and the user can stop at any scale when rotating. For example, rotating from 1.0 to 1.32, etc., to achieve adjustment of an arbitrary value. No matter which form, the user can adjust the button to an arbitrary value according to his / her driving habits, without being limited to a fixed mode.

[0051] In step S102, a target sensitivity of the brake pedal is determined according to the current adjustment value, and a target brake pedal curve of the brake pedal is calculated according to the target sensitivity and a reference brake pedal curve of the brake pedal.

[0052] It can be understood that the embodiments of the present application can determine the target sensitivity according to the current adjustment value of the button, and calculate the target brake pedal curve in combination with the reference brake pedal curve. The method adjusts the brake sensitivity of the vehicle in an unlimited numerical value through the adjustment button, and thus realizes an unlimited number of brake pedal feeling styles in numerical value, which can meet the driving habits of almost all users.

[0053] In the embodiments of the present application, determining the target sensitivity of the brake pedal according to the current adjustment value includes: acquiring a first correspondence table of adjustment values and sensitivities of the adjustment button; and querying the first correspondence table to obtain the target sensitivity of the brake pedal by taking the current adjustment value as an index.

[0054] It is understood that, in this embodiment of the application, the target sensitivity of the brake pedal can be determined based on the current adjustment value. The target sensitivity is obtained by querying a first correspondence table between preset adjustment values ​​and sensitivities, using the current adjustment value as an index.

[0055] The preset correspondence table between adjustment values ​​and sensitivity is a data mapping table pre-set and stored in the ECU (Electronic Control Unit) of the control system. Its function is to establish a precise correspondence between "adjustment values" and "target sensitivity". It can be set manually or according to actual needs, without specific limitations.

[0056] Specifically, such as Figure 2 As shown, the user can drag the adjustment button slider to change its position. Each slight slide generates a corresponding adjustment value in real time. Based on the current adjustment value, the target sensitivity of the brake pedal is determined by looking up the first correspondence table, i.e., the braking sensitivity shown in the figure. The slider positions of "Example 1-Example 5" in the figure correspond to different braking sensitivities from "ultra-slow" to "ultra-sensitive". The output braking sensitivity signal is used to adjust the pedal feel curve. The range of the braking sensitivity signal is determined according to design requirements, for example, 0.5-1.5. When the user adjusts the braking sensitivity by sliding the adjustment button, the braking sensitivity signal changes accordingly within the design range.

[0057] For example, such as Figure 2 As shown, when the user operates the adjustment button slider as in Example 1, with the "Brake Sensitivity Adjustment Bar" positioned slightly to the left, the corresponding signal value may be close to 0.5, resulting in an ultra-slow braking sensitivity signal, the lowest sensitivity, and the "slowest" braking response. When the user operates the adjustment button slider as in Example 3, with the "Brake Sensitivity Adjustment Bar" positioned slightly to the middle, the corresponding signal value may be close to 1.0, representing the default intermediate state and normal braking logic. When the user operates the adjustment button slider as in Example 5, with the "Brake Sensitivity Adjustment Bar" positioned slightly to the right, the corresponding signal value may be close to 1.5, resulting in the highest sensitivity and the "fastest" braking response.

[0058] In this embodiment of the application, before calculating the target brake pedal curve based on the target sensitivity and the reference brake pedal curve of the brake pedal, the method further includes: obtaining a second correspondence table between the vehicle's driving mode and the brake pedal curve; and querying the second correspondence table using the vehicle's current driving mode as an index to obtain the reference brake pedal curve of the brake pedal.

[0059] The second correspondence table between driving modes and brake pedal curves is a pre-set data mapping table stored in the ECU of the control system. Its function is to establish the correspondence between "driving modes" and "brake pedal curves". It can be set manually or according to actual needs, without specific limitations. The brake pedal curve is the basic pedal feel curve, which is a reference pedal feel curve or three pedal feel curves pre-calibrated during pedal feel calibration.

[0060] It is understood that the embodiments of this application can obtain a reference brake pedal curve through a preset second correspondence table between driving modes and brake pedal curves. This serves as the basis for subsequent calculation of the target brake pedal curve. This method achieves adaptation of brake pedal feel to driving mode, making the pedal feel more in line with the driving needs of that mode and improving the user's driving experience.

[0061] Specifically, such as Figure 3 As shown, the second mapping table stores different driving modes, such as Comfort, Standard, and Sport, corresponding to the three curves in the diagram, and their mapping relationships with the corresponding brake pedal curves. For example, when the driving mode is Comfort, it is associated with the "Comfort Mode Curve," where deceleration increases most gradually with pedal travel, resulting in a soft brake feel; this brake pedal curve serves as the reference brake pedal curve. Similarly, when the driving mode is Sport, it is associated with the "Sport Mode Curve," where deceleration increases most sharply with pedal travel, resulting in a sensitive brake feel. When the driving mode is Standard, it is associated with the "Standard Mode Curve," whose characteristics fall between the two.

[0062] In this embodiment of the application, the target brake pedal curve is calculated based on the target sensitivity and the reference brake pedal curve of the brake pedal, including: processing the target sensitivity and the reference brake pedal curve of the brake pedal using a linear product or interpolation method to obtain the target brake pedal curve of the brake pedal.

[0063] It is understood that the embodiments of this application can calculate the target brake pedal curve based on the target sensitivity and the reference brake pedal curve. The target brake pedal curve is calculated by combining the target sensitivity and the reference brake pedal curve through linear multiplication or interpolation. This achieves the conversion from target sensitivity to a specific braking curve, ensuring that the user's adjustment needs for "sensitivity" are directly reflected in the actual changes in pedal feel, improving the intuitiveness and effectiveness of the adjustment.

[0064] Specifically, the reference braking curve serves as a "base template," which can be adjusted using linear multiplication or interpolation to obtain a target curve that conforms to both the driving mode and the user's habits, based on the user's adjusted target sensitivity. For example... Figure 4As shown, after the user adjustment is completed, the brake sensitivity signal is transmitted to the ECU, the ECU performs adaptive adjustment on the base pedal feel curve through calculation, which can be controlled by linear multiplication or interpolation method; the calculated pedal feel curve is applied as the current state, so that when the user steps on the brake pedal, the hydraulic pressure and deceleration output by the same pedal stroke are changed accordingly compared with before the adjustment, so as to achieve the desired effect of user adjustment of brake sensitivity.

[0065] In step S103, the vehicle is controlled to perform a braking action according to the target brake pedal curve.

[0066] It can be understood that the braking action is to make the vehicle realize smooth and efficient deceleration or parking operation according to the requirements of the target brake pedal curve through a series of mechanical, hydraulic and electronic control processes.

[0067] In the embodiments of the present application, after the vehicle is controlled to perform a braking action according to the target brake pedal curve, the braking reminder information of the vehicle is generated, and the user is reminded by using the braking reminder information.

[0068] It can be understood that after the braking action is completed, the braking reminder information can be generated to remind the user. Through information feedback, the user can clearly perceive the relationship between the abstract sensitivity setting and the actual braking effect, which facilitates the user to adjust the sensitivity and adapt to different pedal feel styles, and improves the use experience.

[0069] For example, when the braking action is completed, the instrument briefly displays the text "braking is completed, the deceleration of this braking is 2.5m / s 2 , corresponding to the sensitivity too high mode set by you", and the screen pops up a dynamic curve diagram showing the correspondence between the pedal stroke and the braking force, which disappears automatically after 3 seconds. This helps the user to intuitively perceive the actual braking effect under the current sensitivity setting, strengthens the association between the adjustment operation and the braking result, and makes the user more clearly understand the performance of the sensitivity set by himself in the actual braking, which is convenient for subsequent further optimization adjustment.

[0070] According to the control method of the unlimited brake pedal feel proposed in the embodiments of the present application, any current adjustment value of the adjustment button can be obtained, the target sensitivity is determined according to the current adjustment value, the target brake pedal curve is calculated combined with the reference curve, and the vehicle is controlled according to the target curve. This method realizes unlimited brake pedal feel styles in numerical value by adjusting the numerical value of the brake sensitivity of the vehicle, which can meet the driving habits of almost all users and improve the driving comfort; without additional hardware, the cost is low, the user complaints are reduced, and the driving safety risk caused by the pedal feel is reduced.

[0071] The embodiments of the present application will be described below in conjunction with Figure 5The infinite pedal feeling control principle of the present application is described in detail as follows: as shown in Figure 5 The present application mainly consists of an entity or virtual adjustment button, a pedal feeling simulator, an ECU, an assistance system, an execution system, and a reminding system, and the specific configuration is as follows:

[0072] 1) Virtual or entity adjustment button: output brake sensitivity signal through user adjustment.

[0073] 2) Pedal assembly: user performs brake operation through brake pedal.

[0074] 3) Pedal feeling simulator: output push rod stroke signal according to user's pedal stepping.

[0075] Specifically, the pedal assembly and the pedal feeling simulator are mechanically connected, and the pedal feeling simulator and the control system and the assistance system can be integrated into one module.

[0076] 4) Control system: according to brake sensitivity and push rod stroke signal, output pressure building target request to assistance system after control strategy calculation.

[0077] 5) Assistance system: receive pressure building request from control system, output hydraulic pressure meeting target demand to execution system.

[0078] 6) Execution system: output brake torque to slow down vehicle, which can be generated by four-wheel brake or brake energy recovery system or simultaneously. The execution system includes front and rear brake assembly and brake energy recovery system.

[0079] 7) Reminding system: receive signal from control system, after user sets brake sensitivity, feedback pedal feeling style setting information to driver in the form of image and sound through multimedia and instrument. The reminding system includes: instrument: provide information to driver in the form of text, image, sound, etc.; multimedia: provide information to driver in the form of text, image, sound, etc.

[0080] Specifically, in the reminding system, after user sets brake sensitivity, instrument or multimedia large screen or simultaneously displays pedal feeling state information to user, which can include text, image, sound reminder. When brake sensitivity adjustment approaches boundary, for example, in the range of slow-very slow, sensitive-very sensitive, instrument or multimedia large screen performs text, image, sound reminder, and the reminder information is for example "current brake sensitivity is too low, please drive carefully" and "current brake sensitivity is too high, please drive carefully". Brake sensitivity setting can be memorized by vehicle, and after vehicle is powered on again, brake pedal feeling is the state after user adjustment last time.
