Description

[0002] In order to improve energy utilization and increase driving range, existing new energy vehicles are equipped with a combined regenerative braking system (CRBS). During the use of new energy vehicles, most of the braking force required for vehicle deceleration in conventional scenarios comes from the kinetic energy recovery of the motor, so that the proportion of mechanical braking involved in braking is getting lower and lower. Only when emergency braking occurs and the motor kinetic energy recovery torque is insufficient to provide emergency braking force requirements, does the mechanical brake provide additional braking force. This leads to a decrease in the frequency of mechanical braking participation, causing a layer of oxide to adhere to the brake disc for a long time and cannot be removed. At this time, if emergency braking occurs, the rusty brake disc will cause the mechanical braking capacity to decrease, the braking distance to increase, and cause a collision accident.

[0003] In the prior art, the number of braking times is obtained, and when the number of braking times reaches a preset number, the brake disc is used to perform braking and rust removal on the brake disc, but this method has poor flexibility. Summary of the invention

Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment.

[0052] In the various embodiments of the present application, it should be understood that the size of the serial numbers of the following processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0053] In the embodiments provided in the present application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined according to A. However, it should also be understood that determining B according to A does not mean determining B only according to A, and B can also be determined according to A and / or other information.

[0055] In order to solve the problem of poor flexibility of existing brake rust removal methods, embodiments of the present invention provide a vehicle brake rust removal control method, device, equipment, medium and program product.

[0056] like Figure 1 As shown, an embodiment of the present invention provides a vehicle brake rust removal control method, comprising:

[0057] Step 101: After the vehicle is powered on, date information related to the vehicle brake rust removal and environmental information of the vehicle are obtained.

[0058] In this step, after the controller of the vehicle is powered on, the date information related to the brake rust removal of the vehicle is read through the controller and the environmental information of the vehicle is collected through the sensor.

[0059] The date information related to the vehicle brake rust removal includes:

[0060] Current power-on date, where the current power-on date refers to the date when the vehicle is powered on, including the current power-on year, current power-on month and current power-on day;

[0061] The date when the vehicle last underwent brake rust removal, wherein the date when the vehicle last underwent brake rust removal refers to the date when the last brake rust removal was completed, including the year when the vehicle last underwent brake rust removal, the month when the vehicle last underwent brake rust removal, and the day when the vehicle last underwent brake rust removal.

[0062] The vehicle environment information includes at least one of the following:

[0063] The ambient temperature of the vehicle;

[0064] The humidity of the environment in which the vehicle is located;

[0065] The rainfall information sensed by the vehicle in the last power-on cycle, wherein the rainfall information is obtained by using a rain sensor on the vehicle. If the rain sensor senses that it is raining or the vehicle is being washed and exposed to water, the water value is accumulated and stored, and is stored when the power is turned off, that is, the rainfall information includes the accumulated water value in the last power-on cycle. It can be understood that the last power-on cycle of the vehicle refers to the power-on cycle adjacent to the current power-on cycle.

[0066] Step 102: Determine the rust-unremoved time of the vehicle according to the date information and the environmental information.

[0067] In this step, the future rust removal time of the vehicle is calculated based on the above date information and environmental information. That is, when calculating the rust-free time of the vehicle, not only the difference between the simple dates is considered based on the date information, but also the gain value generated by the environmental information is considered, so that the obtained rust-free time of the vehicle can more accurately reflect whether the vehicle needs rust removal.

[0068] Optionally, the duration of time during which the vehicle has not been rust-removed may be measured in days.

[0069] Step 103: When the rust removal time is longer than a preset time, the real-time driving speed and the real-time brake pedal depression depth of the vehicle during driving are obtained.

[0070] In this step, if the rust removal time is longer than the preset time, the "brake disc rust removal strategy" is activated, that is, the brake disc rust removal strategy is activated, and mechanical braking is used to determine that the brake disc rust removal can be performed. Otherwise, the rust removal strategy is not activated, and the normal kinetic energy recovery strategy is used, with motor kinetic energy recovery braking as the main method.

[0071] The real-time driving speed may include recorded values ​​of two units, including a speed value 1 in “kilometer / hour” and a speed value 2 in “meter / second”.

[0072] Optionally, the rust-unremoved time period may be in days, and the preset time period may also be in days.

[0073] When brake disc rust removal can be performed, after the vehicle starts to travel, the real-time driving speed and the real-time brake pedal depression depth of the vehicle during travel are obtained, and brake disc rust removal is performed based on the real-time driving speed and the real-time brake pedal depression depth.

[0074] The above process can make the activation of the rust removal strategy more flexible and accurate, and ensure less energy consumption with less mechanical braking frequency while achieving better mechanical braking performance.

[0075] In an optional embodiment, determining the un-rusted time of the vehicle according to the date information and the environmental information includes:

[0076] According to the current power-on date and the date when the vehicle last performed brake rust removal, a first duration is obtained, that is, the date difference between the current power-on date and the date when the vehicle last performed brake rust removal, which is the first duration, and the first duration can also be expressed in days.

[0077] An environmental gain value is determined according to the current power-on date, the ambient temperature of the vehicle, and the ambient humidity of the vehicle.

[0078] Specifically, according to the current power-on date, the season of the vehicle when it is currently powered on can be determined, such as summer or winter. The higher the ambient temperature of the vehicle, the higher the gain value, and the higher the ambient humidity of the vehicle, the higher the gain value. For example, in the summer, when the vehicle is in a high temperature and high humidity environment, the environmental gain value is 2, and in the winter, when the vehicle is in a low temperature and dry environment, the environmental gain value is 1.

[0079] Optionally, different months are set to correspond to different seasons, and different seasons correspond to different seasonal gain values. According to the month to which the current power-on date belongs, the seasonal gain value corresponding to the current power-on date is determined; the ambient temperature is divided into multiple temperature intervals, different temperature gain values ​​corresponding to different temperature intervals are set, the temperature interval in which the ambient temperature of the vehicle is located is determined, and the temperature gain value corresponding to the temperature interval is determined; the ambient humidity is divided into multiple humidity intervals, different humidity gain values ​​corresponding to different humidity intervals are set, the humidity interval in which the ambient humidity of the vehicle is located is determined, and the humidity gain value corresponding to the humidity interval is determined. The seasonal gain value, the temperature gain value, and the humidity gain value are multiplied to obtain the ambient gain value.

[0080] A rainfall gain value is determined based on rainfall information sensed by the vehicle in the last power-on cycle. Specifically, when the rainfall information indicates that no water is sensed, the rainfall gain value is determined to be 1; when the rainfall information indicates that water is sensed, the rainfall gain value is determined to be greater than 1, and the more water there is, the greater the rainfall gain value.

[0081] The rust-unremoved time of the vehicle is obtained according to the first time, the environment gain value and the rainfall gain value.

[0082] Specifically, the first time period is multiplied by the environment gain value and the rainfall gain value to obtain the un-rusted time period of the vehicle.

[0083] It should be noted that, in the embodiment of the present invention, all types of gain values ​​are values ​​greater than or equal to 1.

[0084] In some embodiments, the vehicle brake rust removal is performed according to the real-time driving speed and the real-time brake pedal depression depth, including:

[0085] When the real-time driving speed is greater than the first preset speed and the real-time brake pedal depression depth is greater than or equal to the first preset depth, the vehicle brake rust removal is performed.

[0086] The real-time brake pedal depression depth being greater than or equal to the first preset depth may also be understood as the real-time brake pedal depression depth being greater than or equal to the first brake depression threshold.

[0087] When the real-time driving speed is greater than the first preset speed and the real-time brake pedal depression depth is greater than or equal to the first brake depression threshold, the brake disc rust removal strategy is activated and mechanical braking is adopted. If the above conditions are not met, the rust removal strategy is not activated and the normal kinetic energy recovery strategy is followed, with motor kinetic energy recovery braking as the main method.

[0088] In some embodiments, the method further comprises:

[0089] During the process of derusting the vehicle by braking, determining the derusting distance according to the real-time driving speed and the real-time brake pedal stepping depth;

[0090] When the rust removal distance is greater than a preset distance, it is determined that the vehicle brake rust removal is completed.

[0091] Specifically, according to the real-time brake pedal depression depth, the braking intensity coefficient corresponding to the real-time brake pedal depression depth is determined. After the vehicle braking rust removal starts, the real-time driving speed is multiplied by the braking intensity coefficient and time is integrated to obtain the rust removal distance. When the rust removal distance is greater than the preset distance, it is determined that the vehicle braking rust removal is completed.

[0092] It should also be noted that, when the rust removal distance does not reach the preset distance, if the above-mentioned conditions that the real-time driving speed is greater than the first preset speed and the real-time brake pedal depression depth is greater than or equal to the first preset depth are not met, the vehicle brake rust removal is also stopped. At this time, the rust removal distance that does not reach the preset distance is used as the initial rust removal distance for the next vehicle brake rust removal. When the next vehicle brake rust removal starts, the rust removal distance calculated according to the above process needs to be added to the initial rust removal distance first, and then it is determined whether it is greater than the preset distance.

[0093] As an optional implementation manner, when the rust removal distance is greater than a preset distance, determining that the vehicle brake rust removal is completed includes:

[0094] When the rust removal distance is greater than the preset distance and the real-time brake pedal depression depth is less than the second preset depth, it is determined that the vehicle brake rust removal is completed.

[0095] The second preset depth is smaller than the first preset depth, and the second preset depth is a smaller value.

[0096] In this optional implementation, when the rust removal distance reaches the threshold during a certain period of stepping on the brake pedal, but the brake pedal is still not released, the rust removal is not completed, in order to avoid the unevenness and cumbersome calibration work caused by the transition from mechanical braking to kinetic energy recovery braking during this braking period. Rust removal can only be completed after the brake pedal is released. If the brake pedal is stepped on again afterwards, it cannot be activated again according to the activation conditions of the rust removal strategy, and the conventional kinetic energy recovery strategy is executed.

[0097] Further, determining the rust removal distance according to the real-time driving speed and the real-time brake pedal depression depth includes:

[0098] Divide the depth range in which the vehicle brake pedal can be stepped on into multiple depth intervals;

[0099] Determining a braking intensity coefficient corresponding to the real-time brake pedal stepping depth according to the depth interval of the real-time brake pedal stepping depth;

[0100] The brake pedal depression depth represents the strength of the brake. The deeper the pedal is depressed, the stronger the braking strength is. The stronger the braking strength is, the higher the rust removal efficiency is. Different depth intervals correspond to different braking strength coefficients. Specifically, the system defines the brake pedal depression depth range as 0 to 100%, and divides the range into n (n is an integer greater than or equal to 1) depth intervals:

[0101] 0<=brake pedal depression depth<brake pedal threshold 1;

[0102] Brake pedal threshold 1 <= brake pedal depression depth < brake pedal threshold 2;

[0103] Brake pedal threshold 2 <= brake pedal depression depth < brake pedal threshold 3; ......

[0105] Brake pedal threshold (n-1) <= brake pedal depression depth < brake pedal threshold (n);

[0106] Among them, the brake pedal threshold (n) is equal to 100%.

[0107] The above brake pedal depth ranges correspond to the brake strength coefficients: brake strength coefficient 1, brake strength coefficient 2... brake strength coefficient (n), which is proportional to the brake pedal depression depth and ranges from [0 to 1]. The purpose of setting this strength coefficient is to distinguish the degree of clamping of the brake friction pad on the brake disc when shallow braking and deep braking are performed. The rust removal effect is different on different models, so calibration is required to achieve the expected effect. In principle, light braking requires more accumulated mileage than the actual mileage, while heavy braking mileage can be calculated according to the actual mileage.

[0108] The rust removal distance is determined according to the braking intensity coefficient and the real-time driving speed. Specifically, the braking intensity coefficient is multiplied by the real-time driving speed and then time-integrated to obtain the rust removal distance.

[0109] In an optional embodiment, the method further includes:

[0110] After the vehicle brake rust removal is completed, if the vehicle's running speed in the current power-on cycle is greater than the second preset speed, the vehicle power-off date corresponding to the current power-on cycle is used as the date for the vehicle's brake rust removal this time.

[0111] The fact that the driving speed of the vehicle in the current power-on cycle is greater than the second preset speed can be understood as that the driving speed of the vehicle at any moment in the current power-on cycle is greater than the second preset speed.

[0112] That is, after the vehicle brake rust removal is completed, if the vehicle's driving speed in the current power-on cycle is greater than the second preset speed, then after power is turned off, the power-off date is recorded as the date of this brake rust removal, otherwise, the date of this brake rust removal is the date when the last brake rust removal was completed.

[0113] Combine the following Figure 2 , specifically describe the specific process of the vehicle brake rust removal control method provided by the embodiment of the present invention:

[0114] The vehicle controller is powered on, and reads the date when the vehicle last underwent brake rust removal and the rainfall information sensed by the vehicle in the last power-on cycle, collects the current power-on date, the ambient temperature of the vehicle, and the ambient humidity of the vehicle, determines the environmental gain value according to the current power-on date, the ambient temperature of the vehicle, and the ambient humidity of the vehicle, determines the rainfall gain value according to the rainfall information, and multiplies the first time length obtained by subtracting the date when the vehicle last underwent brake rust removal from the current power-on date by the rainfall gain value and the environmental gain value to obtain the vehicle's un-rusted time length; determines whether the un-rusted time length is greater than a preset time length, if not, the vehicle brake rust removal is not performed, and if so, obtains the real-time driving speed and the real-time brake pedal depression depth, determines whether the real-time driving speed is greater than the first preset speed and the real-time brake pedal depression depth is greater than or equal to the first preset depth, if not, Then adopt a conventional braking strategy. If yes, then adopt a mechanical braking strategy to perform vehicle braking rust removal, and calculate the rust removal distance; determine whether the rust removal distance is greater than the preset distance. If not, return to the step of determining whether the real-time driving speed is greater than the first preset speed and the real-time brake pedal depression depth is greater than or equal to the first preset depth. If yes, the distance reached flag = 1. Then, determine whether the distance reached flag is 1 and whether the real-time brake pedal depression depth is less than the second preset depth. If any one of the items is no, continue to perform vehicle braking rust removal. If both are yes, it is determined that the vehicle braking rust removal is completed; then, determine whether the vehicle's driving speed in the current power-on cycle is greater than the second preset speed. If yes, use the vehicle power-off date corresponding to the current power-on cycle as the date for the vehicle's current braking rust removal; and obtain rainfall information for the current power-on cycle.

[0115] The vehicle brake rust removal control method provided by the embodiment of the present invention can intelligently judge the length of time that the vehicle has not been rusted. If it is judged that the time is too long, the brake disc rust removal strategy can be activated at this power-on. Because the humidity is high in summer and the dryness is different in winter, the brake disc rusts at different speeds when the vehicle is parked for a long time. The vehicle can make gains for the vehicle parking time according to the different environments. Because the brake pedals of different models are adjusted differently (brake pedal depth and braking force), in order to better adapt to different models, the calibration engineer matches the relationship curve between the brake pedal depth and the rust removal effect, and introduces the braking intensity coefficient. By collecting multi-dimensional environmental information, the control unit can intelligently judge the season, environment, and rain conditions during the parking of the vehicle, and obtain whether the brake disc needs to be rusted. More intelligent judgment can make the rust removal strategy more accurately activated, and on the premise of achieving the optimal mechanical braking performance, the optimal energy consumption is guaranteed with the least mechanical braking frequency. By reaching the preset braking distance, the rust removal strategy is completed, which more intuitively reflects the rust removal effect. Improving the adaptability on different models also improves the flexibility of engineers in performance matching.
