Description

Technical Field

[0001] This application relates to the field of electronic brake control technology, and particularly to a method, device, and storage medium for heating brake fluid. Background Art

[0002] Currently, when the ambient temperature is about -10°C or lower, the ambient temperature will affect the braking performance of the vehicle.

[0003] When the vehicle starts in a low-temperature environment, the viscosity of the brake fluid decreases as the temperature drops. During the process of building brake pressure, the viscosity of the brake fluid increases, and the fluidity of the brake fluid becomes poor, affecting the pressure build-up rate in low-temperature conditions, which may affect the release of braking force, the vehicle deceleration, and pose a danger. When the ambient temperature is too low, as the viscosity of the brake fluid increases, it will affect the pedal feel, the brake pedal becomes significantly harder, and at the same time, the brake pedal stroke may be shortened, which may pose a safety hazard. In a low-temperature environment, when the ABS is triggered, it may trigger a fluid replenishment condition, and the fluid replenishment speed in the low-temperature state will also slow down, which may lead to a situation where the brake fluid is insufficient. In the next braking, due to insufficient brake fluid, the deceleration will be affected, posing a danger.

[0004] In view of this, this application is specifically proposed. Summary of the Invention

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0040] Embodiment 1

[0041] The present application provides a method for heating brake fluid, which is applicable to the situation of heating the working environment of a braking system. The present application mainly selects which solenoid valves and / or motor windings need to be energized, and then heats the environment where the brake fluid and the brake controller chip are located, and finally realizes the heating of the flowing brake fluid. Refer to Figure 1 , the method provided by the present application includes the following operations:

[0042] S110. Obtain the current ambient temperature of the vehicle.

[0043] Obtain the current ambient temperature after the vehicle is unlocked or the door is opened. Among them, the current ambient temperature can be obtained through a temperature sensor outside the vehicle or weather forecast, which is not limited in the present application.

[0044] S120. Determine the target solenoid valves and / or motor windings that need to be energized in the electronic brake system according to the ambient temperature.

[0045] The basic principle is that the lower the ambient temperature, the more solenoid valves need to be energized to ensure the heating effect.

[0046] Optionally, if the ambient temperature is lower than the first threshold and higher than the second threshold, determine the first number of solenoid valves that need to be energized in the electronic brake system as the target solenoid valves; if the ambient temperature is lower than the second threshold and higher than the third threshold, determine the second number of solenoid valves that need to be energized in the electronic brake system as the target solenoid valves; if the ambient temperature is lower than the third threshold, determine the second number of solenoid valves that need to be energized in the electronic brake system as the target solenoid valves, and determine the motor windings that need to be energized.

[0047] Among them, the first threshold > the second threshold > the third threshold. Exemplarily, the first threshold is 0 °C, the second threshold is -10 °C, and the third threshold is -20 °C.

[0048] The first number is less than the second number. Preferably, the first number of solenoid valves includes multiple master cylinder isolation valves CSV; the second number of solenoid valves includes multiple master cylinder isolation valves CSV and multiple pressure building isolation valves PSV. Of course, the second number of solenoid valves can also include other valve bodies in the electronic brake system, such as a switching analog valve SSV and a booster valve ISO.

[0049] Since the CSV is a master cylinder isolation valve, it is in a fully open state by default and filled with brake fluid. Therefore, when the ambient temperature is lower than the first threshold and higher than the second threshold, preferentially heating the CSV can achieve a rapid heating effect. The PSV is a motor master cylinder isolation valve or a pressure building isolation valve, which is in a fully closed state by default and is heated when the ambient temperature is lower than the second threshold. There is no brake fluid flowing through the motor winding, but it is very close to the pipeline where the brake fluid flows, and certain heat conduction can also be carried out. Therefore, it is heated when the ambient temperature is lower than the third threshold.

[0050] The electronic brake system adopted in this application includes a mechanical brake pipeline and an electronically assisted brake pipeline. The structure of the existing electronic brake system is adopted, and this application will not elaborate on it.

[0051] S130. Energize the target solenoid valve and / or motor winding to increase the temperature of the working environment of the brake system to heat the brake fluid.

[0052] Energize the target solenoid valve with a target current, where the target current is greater than the working current of the target solenoid valve and less than the limit current. Energize the motor winding with its working current.

[0053] Generally, according to the magnitude of the heating current, the solenoid valve has three states: 1. 0A represents the non-energized state, at this time the CSV is conducting and the PSV is closed; 2. The holding state or the maintaining state, at this time the solenoid valve has a pre-charge current, which is less than the working current and is not sufficient to open or close the solenoid valve; 3. The working state: there is a working current in the solenoid valve, which is greater than the pre-charge current and less than the target current for heating. This application adds a heating state for the solenoid valve: there is a target current in the solenoid valve, which is greater than the working current and less than the limit current. The limit current is the maximum current that the solenoid valve can withstand.

[0054] Further, in order not to affect normal braking operation, ensure the normal operation of the solenoid valve, and avoid failures caused by long-term large currents, after S130, it includes that after meeting the heating cut-off conditions, if there is a pressure build-up requirement, the current is decayed to the working current; if there is no pressure build-up requirement, the current is decayed to the pre-charge current and maintained; the cut-off conditions include vehicle power-on self-check, being greater than the preset heating duration or having a pressure build-up requirement.

[0055] Exemplarily, after the vehicle is powered on by the key, if the brake pedal is not depressed, there is no pressure build-up requirement, and the current heating current is decayed to the pre-charge current and maintained.

[0056] Exemplarily, after the vehicle steps on the brake pedal and is powered on, there is a pressure build-up requirement, then the current heating current is decayed to the working current; if there are other valves also being energized for heating, it is decayed to the pre-charge current.

[0057] Exemplarily, before the vehicle is powered on and self-checked, if the brake pedal is depressed and there is a pressure build-up requirement, for example, when the vehicle starts on a slope, the current heating current is decayed to the working current; if there are other valves also being energized for heating, it is decayed to the pre-charge current.

[0058] After the vehicle is powered off, the target solenoid valve and the motor winding are not energized, and the target solenoid valve is in the non-energized state.

[0059] In this application, the temperature of the brake fluid and the chip environment is raised by electric heating. The performance of the heated brake fluid is better, ensuring the efficiency of pressure build-up and fluid replenishment, and thus ensuring braking safety. Further, in this application, different numbers of energized solenoid valves are set for different ambient temperatures to achieve staged heating, taking into account both heating efficiency and energy-saving requirements.

[0060] During the heating process of this application, if there is a need for pressure build-up, the current is reduced to the working current to ensure the normal operation of the solenoid valves (CSV and / or PSV), avoiding failures caused by long-term large currents; after heating is completed (for example, when it is greater than the preset heating duration), the current decays to the pre-charge current and is maintained; after the vehicle is powered off, the current decays to the 0A state. This application provides an energized heating strategy for the solenoid valves throughout the cycle, effectively ensuring the response efficiency and safety of braking.

[0061] Further, after energizing the target solenoid valve and / or the motor winding, it further includes: recording the information of the target solenoid valve participating in heating this time; when heating is carried out next time, the solenoid valve that did not participate in heating last time is preferentially selected for heating, so that different solenoid valves can be heated in turn within a period of time to ensure the balance of the service life of the solenoid valves.

[0062] For example, according to the current ambient temperature, multiple master cylinder isolation valves CSV should be heated, but these multiple master cylinder isolation valves CSV have participated in heating last time, then multiple pressure build-up isolation valves PSV are preferentially heated.

[0063] Embodiment 2

[0064] This application provides another method for heating brake fluid, which is applicable to the situation of heating the working environment of the braking system. This application mainly determines the heating current value for the solenoid valves and / or motor windings that need to be energized, and then heats the environment where the brake fluid and the brake controller chip are located, and finally realizes the heating of the flowing brake fluid. Refer to Figure 2 , the method provided by this application includes the following operations:

[0065] S210. Obtain the current ambient temperature of the vehicle and the target solenoid valve and / or motor winding that needs to be energized.

[0066] The target solenoid valve in this embodiment can be all the solenoid valves in the by-wire braking system, or several specified solenoid valves, such as multiple master cylinder isolation valves CSV and multiple pressure build-up isolation valves PSV, or the solenoid valves determined according to the current ambient temperature. Refer to the description of S120. Preferably, record the information of the target solenoid valve participating in heating last time, and select the solenoid valve that did not participate in heating last time for heating this time.

[0067] Obtain the current ambient temperature after the vehicle is unlocked or the door is opened. Herein, the current ambient temperature can be obtained through a temperature sensor outside the vehicle or weather forecast, and the present application does not make a limitation.

[0068] S220. Determine the heating current value according to the current ambient temperature.

[0069] The lower the ambient temperature, the greater the heating current value; the maximum heating current value does not exceed the limit current of the target solenoid valve, and generally does not exceed 2 times the working current.

[0070] Specifically, if the ambient temperature is lower than the first threshold and higher than the second threshold, determine the first heating current value; if the ambient temperature is lower than the second threshold and higher than the third threshold, determine the second heating current value; if the ambient temperature is lower than the third threshold, determine the third heating current value.

[0071] Wherein, the first threshold > the second threshold > the third threshold. The first heating current value < the second heating current value < the third heating current value.

[0072] The present application determines the heating current according to the ambient temperature, taking into account both energy conservation and heating efficiency.

[0073] S230. Energize the target solenoid valve and / or the motor winding according to the heating current value to increase the temperature of the working environment of the braking system to heat the brake fluid.

[0074] Wherein, the motor winding is energized according to the working current of the motor winding.

[0075] Further, in order not to affect normal braking operation, ensure the normal operation of the solenoid valve, and avoid failures caused by long-term large current, after S230, it includes that after meeting the heating cut-off condition, if there is a pressure building requirement, the current is decayed to the working current; if there is no pressure building requirement, the current is decayed to the pre-charge current and maintained; the cut-off conditions include vehicle power-on self-check, being greater than the preset heating duration or having a pressure building requirement.

[0076] Exemplarily, after the vehicle is powered on by the key, if the brake pedal is not depressed, there is no pressure building requirement, and the current heating current is decayed to the pre-charge current and maintained.

[0077] Exemplarily, after the vehicle is powered on with the brake pedal depressed, if there is a pressure building requirement, the current heating current is decayed to the working current; if there are other valves also being energized for heating, it is decayed to the pre-charge current.

[0078] Exemplarily, before the vehicle is powered on and self-checked, if the brake pedal is depressed and there is a pressure building requirement, such as when the vehicle starts on a slope, the current heating current is decayed to the working current; if there are other valves also being energized for heating, it is decayed to the pre-charge current.

[0079] After the vehicle is powered off, the target solenoid valve and the motor winding are not energized, and the target solenoid valve is in an unenergized state.

[0080] In a preferred embodiment, if the ambient temperature is lower than the third threshold and the vehicle is in an extremely cold state, all solenoid valves and motor windings can be energized. When actively building pressure during the energization heating process, the pressure build-up isolation valve PSV and the master cylinder isolation valve CSV will be attenuated to the working current, and other valves will be attenuated to the pre-charge current, waiting to participate in the subsequent actions of pressure build-up.
