Description

Technical Field

[0001] The present disclosure relates to the field of vehicle control, and in particular to a method, device, medium, electronic equipment, and vehicle for venting an oil chamber of a limited-slip differential. Background Art

[0002] A limited-slip differential (LSD) can be installed in a vehicle's drivetrain to allow the left and right wheels to rotate at different speeds. While driving, the left and right wheels often roll at different speeds, especially when cornering or on uneven surfaces. LSDs can help achieve this. However, when driving on icy, muddy, or slippery surfaces, the grip of the wheels on each side can differ significantly. The side with less grip can slip and spin, rendering the vehicle immobile. To address this issue, a LSD is typically used. LSDs primarily use oil in their oil chambers to push pistons against friction plates, achieving partial or full locking of the LSD to accommodate different road conditions. Under normal circumstances, the LSD's oil chambers are filled with oil. However, in some situations, gas can enter the chambers, making it difficult to precisely control the oil pressure, affecting the locking coefficient of the LSD and preventing full locking, thus compromising the vehicle's limited-slip function.

[0003] In the related art, a special instrument is required to detect whether there is gas in the oil chamber of the limited-slip differential and to discharge the gas in the oil chamber. However, it is impossible to accurately detect whether there is gas in the oil chamber of the limited-slip differential and to discharge the gas while the vehicle is driving, which affects the limited-slip function of the limited-slip differential and thus affects the driving experience of the vehicle.

[0036] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0037] It should be noted that, in the present disclosure, words such as "first" and "second" are only used for the purpose of distinguishing descriptions, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying order; terms such as "S101", "S102", "S201", "S202", etc. are used to distinguish steps, and do not necessarily mean that the method steps are performed in a specific order or sequential order; when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0038] First, the application scenarios of the present disclosure are described. The present disclosure can be applied to a vehicle limited slip differential control scenario, particularly a vehicle with a limited slip differential. Figure 1 is a structural diagram of a limited slip differential provided by an embodiment of the present disclosure, such as Figure 1As shown, the limited-slip differential may include an oil chamber 101, a piston 102, a friction plate 103, a one-way valve 104, and a control valve 105. Under normal circumstances, the oil chamber is filled with oil. When the limited-slip function is in effect, the oil enters the oil chamber through the one-way valve and builds up oil pressure. This oil pressure pushes the piston to press against the friction plate. By adjusting the opening of the control valve, the oil pressure in the oil chamber can be precisely controlled, thereby adjusting the locking coefficient of the limited-slip differential according to the locking requirements, achieving partial or full locking of the limited-slip differential to adapt to the needs of different road conditions. However, in some scenarios, gas may enter the oil chamber, making it impossible to accurately control the oil pressure within the oil chamber, affecting the locking coefficient of the limited-slip differential, resulting in an inability to fully lock the limited-slip differential and affecting the vehicle's limited-slip function.

[0039] For example, gas may enter the oil chamber of the limited slip differential in the following scenarios:

[0040] Scenario 1: After the limited-slip differential is assembled, it undergoes testing. During testing, oil must be added to prevent friction plate burnout. After passing the test, the limited-slip differential experiences vibration and rotation during transportation and assembly, which can cause a small amount of gas to form within the oil chamber.

[0041] Scenario 2: When the components of the limited-slip differential (such as the rotor pump, seal ring, etc.) are damaged, the replacement process may cause some gas to appear in the oil chamber.

[0042] When gas appears in the oil chamber, if the limited slip differential is locked, the gas will replace part of the oil and fill the piston cavity. The gas has a low density and a large compression volume, which will cause the compressed oil to not meet the locking pressure of the limited slip differential, resulting in the limited slip differential being unable to lock according to the locking requirements, affecting the vehicle's limited slip function.

[0043] In related technologies, special instruments are required to detect whether there is gas in the oil cavity and to discharge the gas in the oil cavity. However, it is impossible to accurately detect whether there is gas in the oil cavity while the vehicle is driving, which affects the driving experience of the vehicle.

[0044] To address the aforementioned issues, the present disclosure provides a limited-slip differential oil chamber venting method, device, medium, electronic device, and vehicle. These methods can detect and determine the presence of gas within the limited-slip differential oil chamber while the vehicle is traveling in a preset driving pattern, and then vent the gas. Specifically, the method comprises: obtaining a first wheel speed differential when the vehicle is traveling in a first preset driving pattern involving multiple turns; and, based on the first wheel speed differential, controlling the vehicle to travel in a second preset driving pattern also involving multiple turns, if gas is determined to be present within the limited-slip differential oil chamber, thereby venting the gas within the limited-slip differential oil chamber. This method allows for accurate detection and venting of gas within the limited-slip differential oil chamber while the vehicle is traveling, avoiding the problem of the limited-slip differential failing to lock due to gas in the oil chamber and improving the vehicle's driving experience.

[0045] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0046] Figure 2 The embodiment of the present disclosure provides a method for exhausting the oil chamber of a limited slip differential, such as Figure 2 As shown, the method may include:

[0047] S201: Obtain a first wheel speed difference when the vehicle is traveling according to a first preset driving mode.

[0048] The first preset driving mode represents a driving mode in which the vehicle travels at a first preset speed and has multiple turns during the driving process, and the wheel speed difference represents a difference in wheel speed between the left and right wheels of the vehicle.

[0049] For example, the wheel speed of each wheel can be obtained through a wheel speed sensor, and then the absolute value of the difference between the left rear wheel speed and the right rear wheel speed can be used as the first wheel speed difference; or the average of the left front wheel speed and the left rear wheel speed can be used as the left wheel average speed, the average of the right front wheel speed and the right rear wheel speed can be used as the right wheel average speed, and the absolute value of the difference between the left wheel average speed and the right wheel average speed can be used as the first wheel speed difference.

[0050] Furthermore, when the vehicle passes through the above-mentioned multiple turns, the absolute value of the vehicle's steering angle is less than or equal to the preset steering angle. For example, the preset steering angle can be any value between 1 degree and 30 degrees, such as 5 degrees, 10 degrees or 20 degrees.

[0051] For example, the first preset driving mode may be: the vehicle travels along a first preset route at a first preset speed. The first preset route may be an 8-shaped route, an S-shaped route, a U-shaped route, or an H-shaped route. The first preset speed may be any speed between 2 kilometers per hour and 30 kilometers per hour, for example, 7 kilometers per hour, 10 kilometers per hour, or 20 kilometers per hour.

[0052] S202: Determine whether there is gas in the oil chamber of the limited slip differential of the vehicle based on the first wheel speed difference.

[0053] For example, when the first wheel speed difference is greater than or equal to a first preset wheel speed difference threshold, it may be determined that gas exists in the oil chamber of the limited-slip differential of the vehicle.

[0054] The first preset wheel speed difference threshold can be set based on vehicle parameters and empirical values, or can be calibrated based on driving tests of the vehicle under different road conditions. For example, the first preset wheel speed difference threshold can be any value between 30 and 80 rpm, such as 50 rpm, 60 rpm, or 70 rpm.

[0055] It should be noted that if the first wheel speed differential is greater than or equal to the first preset wheel speed differential threshold, gas is present within the limited-slip differential oil chamber. When the limited-slip differential is locked, the air will partially replace the oil and fill the oil chamber. This air is significantly compressed, so the compressed oil cannot meet the locking pressure of the limited-slip differential, resulting in a failure to lock properly and a large wheel speed differential. Therefore, the presence of gas within the vehicle's limited-slip differential oil chamber can be determined using the above method.

[0056] S203 : When it is determined that gas exists in the oil chamber of the limited slip differential, control the vehicle to travel according to a second preset driving mode to discharge the gas in the oil chamber of the limited slip differential.

[0057] The second preset driving mode represents a driving mode in which the vehicle travels at a second preset speed and has multiple turns during the driving process, and the difference between the second preset speed and the first preset speed is within a preset speed difference range.

[0058] For example, the second preset driving mode may be: the vehicle travels along a second preset route at a second preset speed. The second preset route may be the same as or different from the first preset route. For example, the second preset route may be an 8-shaped route, an S-shaped route, a U-shaped route or an H-shaped route. The second preset speed may be greater than the first preset speed. The difference between the second preset speed and the first preset speed may be any value between 1 km / h and 10 km / h. For example, the difference may be 4 km / h, 6 km / h or 7 km / h.

[0059] The above method obtains a first wheel speed difference when a vehicle is traveling according to a first preset driving pattern; determines whether gas is present in the oil chamber of a limited-slip differential of the vehicle based on the first wheel speed difference; and, if gas is determined to be present in the oil chamber, controls the vehicle to travel according to a second preset driving pattern to expel the gas from the oil chamber. The first preset driving pattern represents a vehicle traveling at a first preset speed with multiple turns, and the wheel speed difference represents the difference in wheel speed between the left and right wheels of the vehicle; the second preset driving pattern represents a vehicle traveling at a second preset speed with multiple turns, and the difference between the second preset speed and the first preset speed is within a preset speed difference range. Thus, gas present in the oil chamber of the limited-slip differential can be accurately detected and expelled while the vehicle is traveling, avoiding the problem of the limited-slip differential failing to lock due to gas in the oil chamber and improving the driving experience.

[0060] Furthermore, the above-mentioned step S201 of obtaining the first wheel speed difference when the vehicle is traveling according to the first preset driving mode may include the following steps:

[0061] First, when the limited slip differential of the vehicle is turned on, the vehicle is controlled to travel according to the first preset driving mode.

[0062] Secondly, an average wheel speed difference of the vehicle during driving is obtained, and the average wheel speed difference is used as the first wheel speed difference.

[0063] In another embodiment of the present disclosure, the step S203 of controlling the vehicle to travel according to the second preset driving mode may include: controlling the vehicle to travel a preset mileage according to the second preset driving mode.

[0064] For example, the second preset driving mode can be to control the vehicle to travel along the above-mentioned second preset route at a second preset speed; the preset driving mileage can be a preset multiple of the length of the second preset route, and the preset multiple can be any value greater than or equal to 2, for example, 3, 5 or 8.

[0065] For example, if the second preset route is an 8-shaped route, the vehicle can be controlled to travel 3 to 5 laps along the 8-shaped route at the second preset speed. Furthermore, the driving direction can be changed during driving, for example, driving in a clockwise direction and a counterclockwise direction.

[0066] Furthermore, after controlling the vehicle to travel a preset mileage according to the second preset driving mode, the method further includes:

[0067] First, the vehicle is controlled to travel on a preset road section at a third preset vehicle speed, and a second wheel speed difference during the vehicle's travel is obtained.

[0068] The difference between the adhesion coefficients of the road surfaces on the left and right sides of the preset road section in contact with the vehicle tires is greater than or equal to a preset adhesion coefficient threshold.

[0069] For example, the preset adhesion coefficient threshold can be any value between 0.1 and 0.5, such as 0.2 or 0.4. The road surface in contact with the left tire of the vehicle is a normal road surface, and the adhesion coefficient can be greater than 0.7; the road surface in contact with the right tire of the vehicle is a slippery road surface, and the adhesion coefficient can be less than 0.3. The difference between the two is greater than 0.4, then the condition that the difference in the adhesion coefficients of the road surfaces in contact with the vehicle tires on the left and right sides of the above-mentioned preset road section is greater than or equal to the preset adhesion coefficient threshold is met.

[0070] Likewise, the third preset vehicle speed may be any vehicle speed between 2 kilometers per hour and 30 kilometers per hour, for example, 7 kilometers per hour, 10 kilometers per hour, or 20 kilometers per hour.

[0071] In this way, through the different adhesion coefficients of the left and right roads, the vehicle can more accurately detect whether the limited slip function of the limited slip differential can work normally when driving on this section of road, so as to avoid vehicle slipping.

[0072] It should be noted that the preset road section may be a preset detection road section or a random road section.

[0073] Then, when the second wheel speed difference is less than or equal to a second preset wheel speed difference threshold, it is determined that the gas in the oil chamber of the limited slip differential has been discharged.

[0074] Similarly, the second preset wheel speed difference threshold can be set based on vehicle parameters and empirical values, or calibrated based on driving tests under different road conditions. For example, the second preset wheel speed difference threshold can be any value between 0 and 30 rpm, such as 10 rpm, 15 rpm, or 20 rpm.

[0075] Furthermore, when the second wheel speed difference is greater than or equal to the first preset wheel speed difference threshold, it can be determined that gas still exists in the limited slip differential oil chamber. In this case, step S203 can be performed again to discharge the residual gas.

[0076] In this way, it is possible to detect whether the gas in the oil chamber of the limited slip differential has been completely discharged, thereby ensuring that the locking function of the limited slip differential is fully effective.
