Description

Technical Field

[0001] This disclosure relates to the field of vehicle technology, and in particular to a method, apparatus, device, storage medium, and product for treating brake heat fade. Background Technology

[0002] When a vehicle is subjected to prolonged and continuous braking, the brake discs are continuously clamped by the calipers, causing friction and increased temperature. Once the temperature exceeds a certain threshold, the braking performance will rapidly decline. At this point, the vehicle may experience reduced deceleration or brake failure. Furthermore, when the accumulated heat from repeated braking exceeds the braking system's heat capacity, it can easily generate open flames from the braking system, thereby endangering vehicle safety.

[0003] In related technologies, when a vehicle experiences brake fade, the driver is alerted via HMI (Human-Machine Interface). However, during driving, the HMI alerts are easily ignored, thereby endangering vehicle safety. Summary of the Invention

[0006] Optionally, the method further includes: The ideal acceleration of the vehicle is determined based on the motor's output torque and speed. If the acceleration deviation between the ideal acceleration and the actual acceleration of the vehicle is greater than a preset deviation, it is determined that the vehicle's braking is in a state of heat fade.

[0007] Optionally, the method further includes: The target pedal hardness is determined based on the acceleration deviation, and the target pedal hardness is positively correlated with the acceleration deviation.

[0008] Optionally, determining the target pedal hardness based on the acceleration deviation includes: Determine the target deviation range in which the acceleration deviation lies; The hardness of the brake pedal corresponding to the target deviation range is determined as the target pedal hardness, and one deviation range corresponds to the hardness of one brake pedal.

[0009] Optionally, the method further includes: Determine the braking temperature of the braking system; If the braking temperature is greater than the target temperature threshold, the vehicle's braking is determined to be in a state of thermal fade.

[0010] Optionally, increasing the brake pedal stiffness to the target pedal stiffness includes: Determine the hardness difference between the original pedal hardness and the target pedal hardness; The number of adjustments and the amount of adjustment each time are determined based on the hardness difference. Based on the number of adjustments and the amount of adjustment, the hardness of the brake pedal is increased from the original pedal hardness to the target pedal hardness in multiple stages.

[0011] Optionally, the method further includes: The braking performance of the brake pedal is enhanced from the original braking performance to the target braking performance, wherein, under the same brake pedal travel, the deceleration corresponding to the target braking performance is greater than the deceleration corresponding to the original braking performance.

[0016] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects: If it is determined that the vehicle's brakes are in a state of heat fade, the hardness of the brake pedal is increased to the target pedal hardness. This means that under the same pedal force, the pedal travel corresponding to the target pedal hardness is less than the pedal travel corresponding to the original pedal hardness. By increasing the pedal hardness, the user is more directly alerted that the vehicle's brakes are in a state of heat fade, so as to ensure vehicle safety.

[0017] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0024] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0025] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0026] When a vehicle undergoes prolonged and continuous braking, the brake discs experience increased temperature due to the constant friction caused by the calipers clamping them. Once the temperature exceeds a certain threshold, braking performance rapidly declines. This can lead to reduced deceleration or even brake failure. Furthermore, if the cumulative heat generated from repeated braking exceeds the braking system's heat capacity, it can easily generate flames from the braking system, endangering vehicle safety. For example, regarding track-related heat phenomena, braking engineers have observed an increasing number of customers without professional braking experience driving their personal vehicles on racetracks. This poses a significant challenge to braking systems designed for comfort and everyday driving. When the cumulative heat generated from repeated braking exceeds the braking system's heat capacity, it can easily generate flames from the braking system, endangering vehicle safety.

[0027] In related technologies, when a vehicle experiences brake fade, the driver is alerted via HMI (Human-Machine Interface). However, during driving, the HMI alerts are easily ignored, thereby endangering vehicle safety.

[0028] To address the aforementioned technical problems, this disclosure provides a method, apparatus, device, storage medium, and product for handling brake fade. When it is determined that the vehicle's brakes are in a state of fade, the hardness of the brake pedal is increased to a target pedal hardness. This ensures that, under the same pedal force, the pedal travel corresponding to the target pedal hardness is less than the pedal travel corresponding to the original pedal hardness. By increasing the pedal hardness, the user is more directly alerted that the vehicle's brakes are in a state of fade, thereby ensuring vehicle safety.

[0029] Figure 1 This is a schematic diagram illustrating the structure of a pedal feel simulator according to an exemplary embodiment, such as... Figure 1 As shown, the system may include a brake pedal 101, a first piston cylinder 102, a first control valve 103, a second piston cylinder 104, and / or a second control valve 105 and a third piston cylinder 106. The hardness of the vehicle's brake pedal can be adjusted by controlling the first control valve 103 and / or the second control valve 105, thereby adjusting the pedal feel. Specifically, in the absence of the second control valve 105 and the third piston cylinder 106, different brake pedal hardnesses can be adjusted by controlling the opening degree of the first control valve 103. With the second control valve 105 and the third piston cylinder 106 present, it can be determined that the second piston cylinder 104 corresponds to the piston cylinder in the normal braking state of the vehicle, and the third piston cylinder 106 corresponds to the piston cylinder in the heat faded braking state of the vehicle. When the vehicle's braking is in the normal state, the first control valve 103 is opened and the second control valve 105 is closed. When the vehicle's braking is in the heat faded state, the second control valve 105 is opened and the first control valve 103 is closed, thereby adjusting the pedal feel.

[0030] Figure 2 This is a flowchart illustrating a brake thermal fade treatment method according to an exemplary embodiment, such as... Figure 2 As shown, a controller applicable to a vehicle may include the following steps.

[0031] In step S201, when it is determined that the vehicle's braking is in a state of heat fade, the hardness of the brake pedal is increased to the target pedal hardness, wherein, under the same pedal force, the pedal travel corresponding to the target pedal hardness is less than the pedal travel corresponding to the original pedal hardness.

[0032] In this embodiment, the vehicle's braking can be monitored in real time to determine whether the vehicle's braking is in a state of heat fade. If it is determined that the vehicle's braking is in a state of heat fade, the controller can control the corresponding actuator to increase the brake pedal hardness to a target pedal hardness. The actuator can be a pedal feel simulator. The brake pedal hardness characterizes the correspondence between the brake pedal force and pedal travel. The target pedal hardness is the brake pedal hardness corresponding to the heat fade state; a heat fade state can correspond to a single brake pedal hardness, meaning the target pedal hardness is a fixed value. Alternatively, different brake pedal hardnesses can be determined based on the degree of heat fade, meaning the target pedal hardness is a value that varies with the degree of heat fade.

[0033] The original pedal hardness refers to the current brake pedal hardness, while the target pedal hardness refers to the brake pedal hardness before adjustment. Since the target pedal hardness is the brake pedal hardness increased from the original pedal hardness, a higher pedal hardness results in a shorter pedal travel for the same pedal force. Therefore, under the same pedal force, the pedal travel corresponding to the target pedal hardness is less than the pedal travel corresponding to the original pedal hardness. This allows for adjusting the pedal feel by adjusting the brake pedal hardness. Because the brake pedal is used frequently during driving, the driver can promptly and clearly perceive changes in brake pedal hardness, thus determining whether the vehicle's brakes are experiencing brake fade. For example, the driver can promptly determine if the vehicle's brakes are fading based on an increase in brake pedal hardness, thereby adjusting driving techniques to prevent the vehicle's braking system from overheating and endangering vehicle safety, thus improving vehicle safety.

[0034] In one possible implementation, it can be determined first whether the vehicle's brakes are in a state of heat fade. Specifically, this can be achieved by: Determine the braking temperature of the braking system; if the braking temperature is greater than the target temperature threshold, determine that the vehicle's braking is in a state of thermal fade.

[0035] In this embodiment, the braking temperature of the braking system can be the temperature of the brake disc, and can be determined based on the vehicle's operating parameters. Specifically, the operating parameters may include vehicle inertia information, speed, deceleration, braking time, and braking time interval. The braking temperature of the braking system can be obtained by processing the operating parameters using a corresponding target temperature model. The target temperature model can be obtained by training a base temperature model using sample parameters corresponding to the operating parameters. The sample parameters may include at least one of vehicle inertia information, speed, deceleration, braking time, braking time interval, and the corresponding actual temperature. A target temperature threshold can be preset to determine whether the vehicle's braking is in a state of heat fade. The target temperature threshold can be set according to actual conditions. If the braking temperature is greater than the target temperature threshold, the vehicle's braking is determined to be in a state of heat fade; if the braking temperature is less than or equal to the temperature threshold, the vehicle's braking is determined not to be in a state of heat fade, i.e., the vehicle's braking is in a normal state.

[0036] In one possible implementation, a specific method for determining whether the vehicle's brakes are in a state of heat fade could be: Based on the motor output torque and speed, the ideal acceleration of the vehicle is determined; if the deviation between the ideal acceleration and the actual acceleration of the vehicle is greater than the preset deviation, the vehicle's braking is determined to be in a state of heat fade.

[0037] In this embodiment, the output torque and speed of the motor can be obtained to calculate the ideal acceleration of the vehicle, and the acceleration deviation between the actual acceleration and the ideal acceleration can be calculated. Specifically, the deviation can be calculated by subtracting the ideal acceleration from the actual acceleration, obtaining the acceleration difference, and then dividing the acceleration difference by the ideal acceleration to obtain the acceleration deviation. The relationship between the acceleration deviation and a preset deviation is then determined. If the acceleration deviation is greater than the preset deviation, the vehicle's braking is determined to be in a state of brake fade. The preset deviation can be set according to actual conditions; for example, it can be 10%. If the acceleration deviation is less than or equal to the preset deviation, the vehicle's braking is determined to be in a normal state.

[0038] In one possible implementation, the target pedal hardness can also be determined, specifically by: The target pedal hardness is determined based on the acceleration deviation, and the target pedal hardness is positively correlated with the acceleration deviation.

[0039] In this embodiment, the target pedal hardness can vary with the acceleration deviation, and the target pedal hardness is positively correlated with the acceleration deviation; that is, the greater the acceleration deviation, the greater the target pedal hardness. For example, the target pedal hardness corresponding to the acceleration deviation can be determined based on the pedal hardness curve, which characterizes the correspondence between different acceleration deviations and pedal hardness. Alternatively, the target pedal hardness corresponding to the acceleration deviation can be determined in intervals, with one acceleration deviation interval corresponding to one pedal hardness. The corresponding target pedal hardness can be determined based on the magnitude of the acceleration deviation.

[0040] In one possible implementation, determining the target pedal stiffness based on the acceleration deviation includes: Determine the target deviation range where the acceleration deviation is located; determine the hardness of the brake pedal corresponding to the target deviation range as the target pedal hardness, with one deviation range corresponding to one brake pedal hardness.

[0041] In this embodiment, different acceleration deviations can be divided into multiple deviation ranges, each corresponding to a brake pedal hardness. Based on the acceleration deviation, a target deviation range can be determined, and the brake pedal hardness corresponding to that range can be obtained, thus yielding the target pedal hardness. By using multiple deviation ranges, different acceleration deviations can correspond to different pedal hardnesses, enabling more diverse pedal feel adjustments. Users can determine different degrees of brake fade based on different pedal feels.

[0042] Figure 3 This is a schematic diagram illustrating the hardness curve of a brake pedal according to an exemplary embodiment, such as... Figure 3 As shown, in one possible implementation, the method for increasing the hardness of the brake pedal to the target pedal hardness can be: Determine the hardness difference between the original pedal hardness and the target pedal hardness; determine the number of adjustments and the adjustment amount for each adjustment based on the hardness difference; based on the number of adjustments and the adjustment amount, increase the hardness of the brake pedal from the original pedal hardness to the target pedal hardness in multiple stages.

[0043] In this embodiment, the target pedal hardness is subtracted from the original pedal hardness to obtain the hardness difference between the original and target pedal hardness. The number of adjustments is determined based on the magnitude of this hardness difference. Specifically, different hardness differences can be divided into multiple difference ranges, each corresponding to a number of adjustments. A target difference range is determined, and the number of adjustments corresponding to this target range is set as the final number of adjustments. The hardness difference is then divided by the number of adjustments to obtain the adjustment amount for each adjustment. Then, based on the number of adjustments and the adjustment amount, the brake pedal hardness is increased from the original pedal hardness to the target pedal hardness in multiple adjustments. Specifically, for any given adjustment, the target amount is determined based on the current brake pedal hardness and the adjustment amount. The brake pedal hardness is adjusted to this target amount. After the target amount is reached, the next adjustment is performed using the same method, which will not be repeated here, until the brake pedal hardness reaches the target pedal hardness. Through multiple adjustments, sudden changes in brake pedal hardness can be avoided, preventing brake accidents caused by driver discomfort.

[0044] In one possible implementation, the method further includes: The braking performance of the brake pedal is enhanced from the original braking performance to the target braking performance, wherein, under the same brake pedal travel, the deceleration corresponding to the target braking performance is greater than the deceleration corresponding to the original braking performance.

[0045] In this embodiment, braking performance characterizes the relationship between pedal travel and deceleration. Stronger braking performance corresponds to greater deceleration for the same pedal travel. Therefore, for the same brake pedal travel, the deceleration corresponding to the target braking performance is greater than the deceleration corresponding to the original braking performance. The original braking performance is the current braking performance, and the target braking performance is the braking performance corresponding to heat fade. The target braking performance corresponding to the acceleration deviation can be determined based on the braking performance curve, which characterizes the relationship between different acceleration deviations and braking performance. Alternatively, the target braking performance corresponding to the acceleration deviation can be determined in intervals, with one acceleration deviation interval corresponding to one braking performance. The corresponding target braking performance can be determined based on the magnitude of the acceleration deviation. The target braking performance can also be a fixed value; that is, as long as the vehicle's braking is determined to be in a heat fade state, the corresponding target braking performance can be a preset braking performance. By adjusting the braking performance, the potential weakening of braking performance due to heat fade can be compensated for to a certain extent, thereby ensuring driving safety.

[0046] In one possible implementation, the method further includes: Output a thermal decay warning message.

[0047] In this embodiment, a brake fade warning message can also be displayed through a human-machine interface. This message can be a warning icon or a text prompt, such as directly displaying "Brakes are in a brake fade state" on the human-machine interface. Alternatively, the warning message can be output via voice. This allows for multiple warning methods to provide users with brake fade alerts, achieving a better warning effect.
