Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle control, in particular to a brake disc temperature control method. BACKGROUND

[0002] The brake disc is a component used to impede the movement or movement tendency of a vehicle in a vehicle braking system, which is usually fixed on the vehicle hub to generate braking force by clamping with the friction pad, convert the kinetic energy of the vehicle into heat energy and dissipate to the air, so as to slow down or stop the vehicle.

[0003] When facing a long continuous downhill section, the driver needs to continuously or frequently brake to maintain the vehicle speed, at this time the brake disc cannot dissipate heat to the air in time, and is prone to heat accumulation and overheating failure. In order to avoid the above situation, a temperature sensor and an alarm are provided on the existing vehicle, and when the temperature sensor monitors that the temperature of the brake disc exceeds the predetermined value, an electric signal is sent to the alarm to alarm and prompt the driver to stop the vehicle in time.

[0004] However, the above brake disc temperature monitoring method will make the vehicle need to stop frequently during driving, affecting the driving experience of the vehicle. SUMMARY

[0005] Therefore, the brake disc temperature control method provided by the present application can monitor and prevent the risk of brake disc overheating, and improve the safety and comfort of the vehicle.

[0006] To achieve the above purpose, the present application adopts the following technical solutions:

[0007] The embodiment of the present application provides a brake disc temperature control method, comprising:

[0008] obtaining the current temperature of a plurality of brake discs;

[0009] If the current temperature of at least one of the brake discs is higher than or equal to a first preset temperature, the brake disc is determined as a target brake disc, and a first alarm signal is outputted;

[0010] According to the first alarm signal, a function component is controlled to adjust the current parameters of the target brake disc and other brake discs to reduce the current temperature of the target brake disc.

[0011] In a possible implementation, the function component is set as a pressure control system, and the current parameter is set as brake pressure.

[0012] The function component is controlled to adjust the current parameters of the target brake disc and other brake discs, comprising:

[0013] The pressure regulation system reduces the braking pressure of the target brake disc and increases the braking pressure of the other brake discs.

[0014] In one possible implementation, the braking pressure of the brake disc is the initial braking pressure before the brake disc is determined to be the target brake disc;

[0015] The braking pressure of the target brake disc is reduced by the pressure regulation system, and the braking pressure of the target brake disc is less than or equal to 80% of the initial braking pressure.

[0016] In one possible implementation, based on the first alarm signal, the gear selector is controlled to downshift the vehicle to increase engine speed and perform auxiliary braking.

[0017] In one possible implementation, after determining that the brake disc is the target brake disc, the process includes:

[0018] After a first set time interval, the current temperature of the target brake disc is obtained;

[0019] If the current temperature of the target brake disc is higher than or equal to the first preset temperature, the first alarm signal will be output again.

[0020] In one possible implementation, if the current temperature of at least one of the brake discs is greater than or equal to the first preset temperature, then a set interval is applied.

[0021] After the first set time interval, the current temperature of the target brake disc is obtained again;

[0022] If the current temperature of the target brake disc is higher than or equal to the first preset temperature, then the first alarm signal is output.

[0023] In one possible implementation, the brake disc includes a brake disc body, and acquiring the current temperature of multiple brake discs includes:

[0024] Obtain the measured temperature of the brake disc body;

[0025] The current temperature of the brake disc is determined based on the thermal conductivity of the brake disc body and the measured temperature.

[0026] In one possible implementation, the brake disc includes friction pads, and acquiring the current temperature of multiple brake discs includes:

[0027] Obtain the measured temperature of the friction pad;

[0028] The current temperature of the brake disc is determined based on the thermal conductivity of the friction lining and the measured temperature.

[0029] In one possible implementation, after the control function adjusts the current parameters of the target brake disc and other brake discs, the following is included:

[0030] After a second preset time interval, the current temperature of the target brake disc is obtained again;

[0031] If the current temperature of the target brake disc is higher than or equal to the second preset temperature, a second alarm signal is output; the second preset temperature is higher than the first preset temperature.

[0032] In one possible implementation, the ratio of the second preset temperature to the first preset temperature is greater than or equal to 1.2 and less than or equal to 1.5.

[0033] This application provides a brake disc temperature control method that acquires the current temperature of each brake disc in a vehicle in real time and compares the current temperature of each brake disc with a first preset temperature. If the current temperature of the brake disc is higher than or equal to the first preset temperature, a first alarm signal is output. Simultaneously with outputting the first alarm signal, a control function unit adjusts the current parameters of the target brake disc and other brake discs to reduce the current temperature of the target brake disc until the current temperature of the target brake disc is lower than the first preset temperature. If the current temperature of the brake disc is lower than the first preset temperature, no alarm is triggered.

[0034] Compared to existing brake disc temperature monitoring methods, the brake disc temperature control method provided in this application can monitor and prevent the risk of brake disc overheating, thereby improving vehicle safety and comfort. Attached Figure Description

Detailed Implementation

[0056] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application and how the technical solutions of the embodiments of this application solve the above-mentioned technical problems will be clearly and completely described below with reference to specific embodiments and the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0057] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0058] In the description of the embodiments of this application, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0059] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0060] In this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0061] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0062] Brake discs are components in a vehicle's braking system used to impede the movement or tendency of a vehicle to move. They are usually fixed to the vehicle's wheel hub and generate braking force by clamping with friction pads, converting the vehicle's kinetic energy into heat energy and dissipating it into the air, thereby slowing down or stopping the vehicle.

[0063] When facing long, continuous downhill sections, drivers need to brake continuously or frequently to maintain speed. During this time, the brake discs cannot dissipate heat into the air in time, leading to heat buildup and potential brake disc overheating and failure. To avoid this, existing vehicles are equipped with temperature sensors and alarms. When the temperature sensor detects that the brake disc temperature exceeds a predetermined value, it sends an electrical signal to the alarm to alert the driver to stop immediately.

[0064] However, the aforementioned brake disc temperature monitoring method requires the vehicle to stop frequently during driving, affecting the driving experience.

[0065] Based on this, the present application provides a brake temperature control method that acquires the current temperature of each brake disc in real time and compares the current temperature of each brake disc with a first preset temperature. If the current temperature of the brake disc is higher than or equal to the first preset temperature, a first alarm signal is output. While outputting the first alarm signal, the control function unit adjusts the current parameters of the target brake disc and other brake discs to reduce the current temperature of the target brake disc until the current temperature of the target brake disc is lower than the first preset temperature. If the current temperature of the brake disc is lower than the first preset temperature, no alarm is triggered.

[0066] Compared to existing brake disc temperature monitoring methods, the brake disc temperature control method provided in this application can monitor and prevent the risk of brake disc overheating, thereby improving vehicle safety and comfort.

[0067] The technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0068] Reference Figure 1 , Figure 8 and Figure 9 As shown in the figure, this application provides a brake disc temperature control method, which includes:

[0069] S101. Obtain the current temperature of multiple brake discs.

[0070] Specifically, the brake disc temperature is measured by the brake disc temperature detection device 100 to obtain the current temperature of the brake disc. The brake disc temperature detection device 100 includes a connecting frame 110, a connecting member 120, an elastic member 130, a mounting plate 150, and a temperature sensor 140 for measuring the brake disc temperature. One end of the connecting frame 110 is used to connect to the vehicle frame, and the other end of the connecting frame 110 is fitted with the temperature sensor 140. The mounting plate 150 is provided on the outside of the temperature sensor 140. The mounting plate 150 is movably connected to the connecting frame 110 through the connecting member 120, so that the distance between the temperature sensor 140 and the brake disc can be changed by adjusting the distance between the mounting plate 150 and the connecting frame 110. The elastic member 130 is sleeved on the outside of the connecting member 120 to facilitate the adjustment of the position of the mounting plate 150 and the temperature sensor 140 by the operator.

[0071] The mounting plate 150 should be made of a high-temperature resistant and low-thermal-conductivity material, such as alumina ceramic, to reduce the interference of temperature changes of the mounting plate 150 on the temperature sensor 140. The temperature sensor 140 can be a linear thermal temperature sensor or other types of temperature sensors. The temperature sensor 140 can also be directly mounted on the brake 200, which will not be elaborated here.

[0072] S102. Compare the current temperature of the brake disc with the first preset temperature.

[0073] If the current temperature of the brake disc is higher than or equal to the first preset temperature, proceed to step S103.

[0074] If the current temperature of the brake disc is lower than the first preset temperature, proceed to step S101.

[0075] Specifically, the first preset temperature can be set by the staff according to the material of the brake disc and the usage scenario, and is not limited in this application.

[0076] S103. Determine the brake disc as the target brake disc and output the first alarm signal.

[0077] Specifically, the brake disc temperature is measured by the brake disc temperature detection device 100 to obtain the current temperature of the brake disc, and the specific value is transmitted to the vehicle controller 400. If the vehicle controller 400 determines that the current temperature of the brake disc is higher than or equal to the first preset temperature, it outputs a corresponding electrical signal to the alarm device 800, and the alarm device 800 outputs a first alarm signal.

[0078] The alarm device 800 can be an indicator light, a buzzer, or other types of alarm; correspondingly, the first alarm signal can be a light or a sound, which will not be elaborated here.

[0079] S104. Based on the first alarm signal, the control function unit adjusts the current parameters of the target brake disc and other brake discs.

[0080] In the above embodiment, the current temperature of each brake disc of the vehicle is acquired in real time and compared with a first preset temperature. If the current temperature of the brake disc is higher than or equal to the first preset temperature, a first alarm signal is output. At the same time as outputting the first alarm signal, the control function unit adjusts the current parameters of the target brake disc and other brake discs to reduce the current temperature of the target brake disc until the current temperature of the target brake disc is lower than the first preset temperature. If the current temperature of the brake disc is lower than the first preset temperature, no alarm is triggered.

[0081] Compared to existing brake disc temperature monitoring methods, the brake disc temperature control method provided in this application can monitor and prevent the risk of brake disc overheating, thereby improving vehicle safety and comfort.

[0082] Furthermore, refer to Figure 1 , Figure 8 and Figure 9 As shown, in some embodiments, the functional component is configured as a pressure regulation system 300, and the current parameter is configured as braking pressure; the control functional component adjusts the current parameters of the target brake disc and other brake discs, including: reducing the braking pressure of the target brake disc and increasing the braking pressure of other brake discs through the pressure regulation system 300.

[0083] Specifically, when the vehicle controller 400 determines that the current temperature of the brake disc is higher than or equal to the first preset temperature, and controls the alarm device 800 to output the first alarm signal, it also outputs a corresponding electrical signal to the pressure regulation system 300. The pressure regulation system 300 will reallocate the brakes 200, reduce the braking pressure of the target brake disc brake, and increase the braking pressure of other brake disc brakes. While ensuring the stability of the vehicle, it avoids the target brake disc from overheating and failing due to heat accumulation.

[0084] Furthermore, in some embodiments, before the brake disc is determined to be the target brake disc, the braking pressure of the brake disc is the initial braking pressure; the braking pressure of the target brake disc is reduced by the pressure regulation system 300, and the braking pressure of the target brake disc is less than or equal to 80% of the initial braking pressure.

[0085] The vehicle sensor 600 can acquire vehicle driving information in real time, including but not limited to speed, acceleration, tire slip rate and slope angle, and transmit the collected information to the vehicle controller 400 to determine the vehicle's driving status, such as turning left or right, going up or down slopes, acceleration and deceleration.

[0086] When the vehicle controller 400 determines that the current temperature of the brake disc is higher than or equal to the first preset temperature and the pressure control system 300 needs to intervene, the vehicle controller 400 can reasonably adjust the braking pressure of each brake 200 according to the vehicle's driving status. Specifically, in the above embodiment, the braking pressure of the target brake disc is reduced by the pressure control system 300, and the braking pressure of the target brake disc is less than or equal to 80% of the initial braking pressure.

[0087] Reference Figure 2 , Figure 8 and Figure 9 As shown, in some embodiments, the brake disc temperature control method includes:

[0088] S201. Obtain the current temperature of multiple brake discs.

[0089] S202. Compare the current temperature of the brake disc with the first preset temperature.

[0090] If the current temperature of the brake disc is higher than or equal to the first preset temperature, proceed to step S203.

[0091] If the current temperature of the brake disc is lower than the first preset temperature, proceed to step S201.

[0092] S203. Determine the brake disc as the target brake disc and output the first alarm signal.

[0093] S204. Based on the first alarm signal, the control function unit adjusts the current parameters of the target brake disc and other brake discs.

[0094] S205. Based on the first alarm signal, control the gear selector 700 to downshift the vehicle.

[0095] Specifically, steps S203 and S204 are performed simultaneously.

[0096] When the vehicle controller 400 determines that the current temperature of the brake disc is higher than or equal to the first preset temperature, it controls the alarm device 800 to output the first alarm signal. At the same time, it can not only output the corresponding electrical signal to the functional component to control the functional component to adjust the current parameters of the target brake disc and other brake discs to reduce the current temperature of the target brake disc, but also output the corresponding electrical signal to the gear selector 700 to control the gear selector 700 to downshift step by step to reduce the vehicle speed and use engine exhaust for auxiliary braking, thereby sharing some of the braking pressure at the target brake disc.

[0097] Reference Figure 3 , Figure 8 and Figure 9 As shown, in some embodiments, the brake disc temperature control method includes:

[0098] S301. Obtain the current temperature of multiple brake discs.

[0099] S302. Compare the current temperature of the brake disc with the first preset temperature.

[0100] If the current temperature of the brake disc is higher than or equal to the first preset temperature, proceed to step S303.

[0101] If the current temperature of the brake disc is lower than the first preset temperature, proceed to step S301.

[0102] S303. Determine the brake disc as the target brake disc and output the first alarm signal.

[0103] S304. After a first set time interval, obtain the current temperature of the target brake disc.

[0104] S305. Compare the current temperature of the target brake disc with the first preset temperature.

[0105] If the current temperature of the target brake disc is higher than or equal to the first preset temperature, then proceed to step S306.

[0106] If the current temperature of the target brake disc is lower than the first preset temperature, proceed to step S301.

[0107] S306, Output the first alarm signal again.

[0108] S307. Based on the first alarm signal, the control function unit adjusts the current parameters of the target brake disc and other brake discs.

[0109] Specifically, when the vehicle controller 400 determines that the current temperature of the brake disc is higher than or equal to the first preset temperature, and the control alarm device 800 outputs the first alarm signal, the driver can first intervene manually, that is, by lightly pressing the brake pedal 500 or reducing the number of times the brake pedal 500 is pressed, to reduce the braking pressure of the target brake disc and lower the current temperature of the target brake disc.

[0110] After a first set time interval, the temperature of the target brake disc is measured by the brake disc temperature detection device 100 to obtain the current temperature of the target brake disc. If the current temperature of the target brake disc is still higher than or equal to the first preset temperature, it indicates that the human intervention has little effect. The vehicle controller 400 outputs a corresponding electrical signal to the functional component to control the functional component to adjust the current parameters of the target brake disc and other brake discs, and further reduce the current temperature of the target brake disc.

[0111] Specifically, the duration of the first setting can be determined by the staff based on the material of the brake disc and the usage scenario, and is not limited in this application.

[0112] Reference Figure 4 , Figure 8 and Figure 9 As shown, in some embodiments, the brake disc temperature control method includes:

[0113] S401, Obtain the current temperature of multiple brake discs.

[0114] S402. Compare the current temperature of the brake disc with the first preset temperature.

[0115] If the current temperature of the brake disc is higher than or equal to the first preset temperature, proceed to step S403.

[0116] If the current temperature of the brake disc is lower than the first preset temperature, proceed to step S401.

[0117] S403. Determine the brake disc as the target brake disc.

[0118] S404. After a first set time interval, obtain the current temperature of the target brake disc.

[0119] S405. Compare the current temperature of the target brake disc with the first preset temperature.

[0120] If the current temperature of the target brake disc is higher than or equal to the first preset temperature, proceed to step S406.

[0121] If the current temperature of the target brake disc is lower than the first preset temperature, proceed to step S401.

[0122] S406, Output the first alarm signal.

[0123] S407. Based on the first alarm signal, the control function unit adjusts the current parameters of the target brake disc and other brake discs.

[0124] Specifically, when the vehicle controller 400 determines that the current temperature of the brake disc is higher than or equal to the first preset temperature, it marks the brake disc as the target brake disc. At the same time, in order to avoid the vehicle controller 400 misjudging and affecting the comfort of the vehicle, it selects not to control the alarm device 800 to output the first alarm signal.

[0125] After a first set time interval, the temperature of the target brake disc is measured by the brake disc temperature detection device 100 to obtain the current temperature of the target brake disc. If the current temperature of the target brake disc is still higher than or equal to the first preset temperature, the vehicle controller 400 controls the alarm device 800 to output a first alarm signal and outputs a corresponding electrical signal to the functional component to control the functional component to adjust the current parameters of the target brake disc and other brake discs in order to reduce the current temperature of the target brake disc.

[0126] Reference Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, in some embodiments, the brake disc includes a brake disc body, and acquiring the current temperature of multiple brake discs includes:

[0127] S501. Obtain the measured temperature of the brake disc body;

[0128] S502. Determine the current temperature of the brake disc based on the thermal conductivity characteristics of the brake disc body and the measured temperature.

[0129] In some embodiments, the brake disc includes friction pads, and acquiring the current temperature of a plurality of brake discs includes:

[0130] S601. Obtain the measured temperature of the friction lining;

[0131] S602. Determine the current temperature of the brake disc based on the thermal conductivity characteristics of the friction lining and the measured temperature.

[0132] Since the brake disc body generates braking force by clamping with the friction pads, converting the vehicle's kinetic energy into heat energy and dissipating it into the air, thereby slowing down or stopping the vehicle, and since the brake disc body and friction pads are usually made of the same material with consistent thermal conductivity, in practice, the brake disc temperature detection device 100 can measure the temperature of the brake disc body or the temperature of the friction pads. The operator can choose the specific measurement object according to the installation position of the brake disc temperature detection device 100, which will not be elaborated here.

[0133] Reference Figures 7 to 9As shown, in some embodiments, the brake disc temperature control method includes:

[0134] S701: Obtain the current temperature of multiple brake discs.

[0135] S702. Compare the current temperature of the brake disc with the first preset temperature.

[0136] If the current temperature of the brake disc is higher than or equal to the first preset temperature, proceed to step S703.

[0137] If the current temperature of the brake disc is lower than the first preset temperature, proceed to step S701.

[0138] S703: Determine the brake disc as the target brake disc and output the first alarm signal.

[0139] S704. Based on the first alarm signal, the control function unit adjusts the current parameters of the target brake disc and other brake discs.

[0140] S705. After a second preset time interval, the current temperature of the target brake disc is obtained again.

[0141] S706. Compare the current temperature of the target brake disc with the second preset temperature.

[0142] If the current temperature of the target brake disc is higher than or equal to the second preset temperature, proceed to step S707.

[0143] If the current temperature of the target brake disc is lower than the second preset temperature, proceed to step S701.

[0144] S707, outputs the second alarm signal.

[0145] Furthermore, in some embodiments, the ratio of the second preset temperature to the first preset temperature is greater than or equal to 1.2 and less than or equal to 1.5.

[0146] Specifically, after the vehicle controller 400 adjusts the current parameters of the target brake disc and other brake discs and after a second preset time interval, the brake disc temperature detection device 100 measures the temperature of the target brake disc again to obtain the current temperature of the target brake disc and sends the current temperature value to the vehicle controller 400. If the vehicle controller 400 determines that the current temperature of the target brake disc is higher than or equal to the second preset temperature, it means that the temperature of the target brake disc is still rising. The vehicle controller 400 outputs a corresponding electrical signal to the alarm device 800, and the alarm device 800 outputs a second alarm signal to remind the driver to stop the vehicle and perform cooling treatments such as spraying water on the brake disc.

[0147] Similarly, the magnitude of the second preset temperature and the length of the second preset time can be set by the operator according to the material of the brake disc and the usage scenario, and are not limited in this application.

[0148] It should be understood that the various forms of processes shown above can be used to reorder, add, or delete steps.

Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors.
