If the following vehicle runs over the sliding snow, there may be a risk of vehicle skidding and traffic accidents, affecting driving safety. Summary of the Invention

[0080] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0081] An embodiment of the present invention provides a method for clearing snow on the vehicle roof, as Figure 1 shown, the method includes the following steps:

[0082] S110, determining the snow accumulation position on the vehicle roof area.

[0083] The vehicle roof area of this embodiment can be divided into four sub-areas. As Figure 2 shown, the vehicle roof area includes: a first sub-area A1, a second sub-area A2, a third sub-area A3, and a fourth sub-area A4; the first sub-area A1 is located at the front left of the vehicle roof, the second sub-area A2 is located at the front right of the vehicle roof, the third sub-area A3 is located at the rear left of the vehicle roof, and the fourth sub-area is located at the rear right of the vehicle roof.

[0084] A heating plate is installed in the roof area. In order to achieve zoned heating, each sub-region can be correspondingly installed with its own heating plate; or, all sub-regions correspond to one heating plate, and this heating plate can achieve local heating, thereby achieving zoned heating.

[0085] When there is snow on the roof, there may be no snow on some sub-regions and snow on some sub-regions. Therefore, it is necessary to determine the snow position on the roof area.

[0086] In one implementation, determining the snow position on the roof area includes:

[0087] Obtain the current pressure of each sub-region of the roof collected by each pressure sensor, and each pressure sensor is installed in the corresponding sub-region of the roof;

[0088] If the pressure is greater than the preset pressure threshold, it is determined that there is snow in the corresponding sub-region, and the sub-region corresponding to the current pressure greater than the preset threshold is determined as the snow position.

[0089] Specifically, a pressure sensor is installed in each sub-region. When there is snow in the sub-region, due to the weight of the snow, the pressure in this region will increase. Therefore, in this embodiment, it can be judged whether there is snow in this region based on the corresponding situation of each sub-region. That is, when the current pressure of a certain sub-region is greater than the preset pressure threshold, this sub-region can be determined as the snow position.

[0090] S111. Determine the roof heating strategy and the vehicle tilt control strategy according to the snow position.

[0091] The snow may be located in a single sub-region, may be located in two adjacent sub-regions, may be located in two non-adjacent sub-regions, may be located in any three sub-regions, and may also be located in four sub-regions. In this embodiment, in order to make the snow slide off the roof quickly, if the snow position is different, the corresponding roof heating strategy and vehicle tilt control strategy are also different.

[0092] In this embodiment, the vehicle tilt control strategy is achieved by adjusting the height of the air suspension, and the suspension height corresponding to each wheel can be adjusted independently. It should be noted that when adjusting the height of the air suspension, the tilt angle of the vehicle is less than the safe tilt angle of the vehicle to avoid the vehicle from tipping over. Among them, the safe tilt angle can be determined based on each vehicle model and will not be elaborated here.

[0093] In one implementation, the determining the roof heating strategy and the vehicle tilt control strategy according to the snow position includes:

[0094] If it is determined that the position is located in the target single region, correspondingly heat the target single region, control the height of the target single region to decrease, and at the same time control the height of the opposite region of the target single region to increase; among them,

[0095] When the target single area is the first sub - area, the opposing area is the fourth sub - area;

[0096] When the target single area is the second sub - area, the opposing area is the third sub - area;

[0097] When the target single area is the third sub - area, the opposing area is the second sub - area;

[0098] When the target single area is the fourth sub - area, the opposing area is the first sub - area.

[0099] For example, if there is snow accumulation in the first sub - area A1 and no snow in other sub - areas, only heat the first sub - area A1, control the height of the first sub - area A1 to decrease, and at the same time control the height of the fourth sub - area A4 to increase. That is, adjust the air suspension to lower the attitude of the left front wheel of the vehicle and raise the attitude of the right rear wheel.

[0100] In one implementation, determine the roof heating strategy and vehicle tilt control strategy according to the snow accumulation position, including:

[0101] If it is determined that the snow accumulation position is in any two adjacent areas in the roof area, then heat the two adjacent areas, control the height of the adjacent areas to decrease, and at the same time control the height of the opposing areas of the adjacent areas to decrease; where

[0102] When the adjacent areas include the first sub - area and the second sub - area, the opposing areas of the adjacent areas include the third sub - area and the fourth sub - area;

[0103] When the adjacent areas include the first sub - area and the third sub - area, the opposing areas of the adjacent areas include the second sub - area and the fourth sub - area;

[0104] When the adjacent areas include the third sub - area and the fourth sub - area, the opposing areas of the adjacent areas include the first sub - area and the second sub - area;

[0105] When the adjacent areas include the second sub - area and the fourth sub - area, the opposing areas of the adjacent areas include the first sub - area and the third sub - area.

[0106] For example, assume that there is snow accumulation in both the first sub - area A1 and the second sub - area A2. Then heat the first sub - area A1 and the second sub - area A2, and at the same time lower the height of the first sub - area A1 and the second sub - area A2, and raise the height of the third sub - area A3 and the fourth sub - area A4. That is, by adjusting the air suspension, lower the front wheels of the vehicle and raise the rear wheels.

[0107] In one implementation, determine the roof heating strategy and vehicle tilt control strategy according to the snow accumulation position, including:

[0108] If it is determined that the snow accumulation position is in any two non - adjacent sub - regions in the roof area, the sub - region with a larger snow accumulation thickness is obtained.

[0109] Heat the sub - region with a larger snow accumulation thickness, control the height of the sub - region with a larger snow accumulation thickness to decrease, and at the same time control the height of the sub - region with a smaller snow accumulation thickness to increase.

[0110] When the sub - region with a larger snow accumulation thickness is cleared, heat the sub - region with a smaller snow accumulation thickness, control the height of the sub - region with a larger snow accumulation thickness to increase, and at the same time control the height of the sub - region with a smaller snow accumulation thickness to decrease.

[0111] In this embodiment, the snow accumulation thickness is determined by the pressure values of each sub - region. If the pressure is large, it indicates a large snow accumulation thickness; if the pressure is small, it indicates a small snow accumulation thickness.

[0112] For any two non - adjacent sub - regions, the sub - region with a larger snow accumulation thickness is preferentially cleared. For example, if there is snow accumulation in the first sub - region A1 and the fourth sub - region A4, and the snow accumulation thickness in the first sub - region A1 is larger and the snow accumulation thickness in the fourth sub - region A4 is smaller, then the snow in the first sub - region A1 is preferentially cleared. Specifically: heat the first sub - region A1, control the height of the first sub - region A1 to decrease, and at the same time control the height of the fourth sub - region A4 to increase. That is, by adjusting the air suspension, the attitude of the vehicle's left front wheel is lowered and the attitude of the right rear wheel is raised.

[0113] Then the vehicle height returns to the initial state, and then the snow in the fourth sub - region A4 is cleared. Specifically: heat the fourth sub - region A4, control the height of the fourth sub - region A4 to decrease, and at the same time control the height of the first sub - region A1 to increase. That is, by adjusting the air suspension, the attitude of the vehicle's left front wheel is raised and the attitude of the right rear wheel is lowered.

[0114] In one implementation, according to the snow accumulation position, a roof heating strategy and a vehicle tilt control strategy are determined, including:

[0115] If it is determined that the snow accumulation position is in any three sub - regions in the roof area, two adjacent regions are determined according to the three sub - regions;

[0116] Determine the adjacent region with a larger snow accumulation thickness in the two adjacent regions as the target adjacent region, heat the target adjacent region, control the height of the target adjacent region to decrease, and at the same time control the height of the opposite region of the target adjacent region to increase;

[0117] When the target adjacent region is cleared, heat the remaining sub - regions except the target adjacent region, control the height of the remaining sub - regions to increase, and at the same time control the height of the opposite regions of the remaining sub - regions to decrease.

[0118] As described above, in this embodiment, the snow depth is determined by the pressure values of each sub-region. If the pressure is high, it indicates a large snow depth; if the pressure is low, it indicates a small snow depth. The snow depth of adjacent regions is the average of the snow depths of two sub-regions in the adjacent regions.

[0119] For example, assume that there is snow in the first sub-region A1, the second sub-region A2, and the third sub-region A3. Then there are two adjacent regions: the first adjacent region and the second adjacent region. Among them, the first adjacent region includes the first sub-region A1 and the second sub-region A2; the second adjacent region includes the first sub-region A1 and the third sub-region A3. If the snow depth of the first adjacent region is large, then the first adjacent region is taken as the target adjacent region, and the snow in the target adjacent region is preferentially cleared. Specifically:

[0120] Heat the first sub-region A1 and the second sub-region A2, control the heights of the first sub-region A1 and the second sub-region A2 to decrease, and the heights of the third sub-region A3 and the fourth sub-region A4 to increase until the snow is cleared. Then restore the vehicle to the normal state (the state where the height of the air suspension is 0), and then heat the third sub-region A3, control the height of the second sub-region A2 to increase, and control the height of the third sub-region A3 to decrease. That is, by adjusting the air suspension, the attitude of the left rear wheel of the vehicle is lowered, and the attitude of the right front wheel is raised.

[0121] In one implementation, the roof heating strategy and the vehicle tilt control strategy are determined according to the snow position, including:

[0122] If it is determined that the snow position is in the four sub-regions of the roof area, four adjacent regions are determined according to the four sub-regions, and the target adjacent region with the largest snow depth and the opposite region of the target adjacent region are determined;

[0123] Heat the target adjacent region, control the height of the target adjacent region to decrease, and at the same time control the height of the opposite region of the target adjacent region to increase;

[0124] When the target adjacent region is cleared, heat the opposite region of the target adjacent region, control the height of the target adjacent region to increase, and at the same time control the height of the opposite region of the target adjacent region to decrease.

[0125] For example, assume that there is snow accumulation in the first sub-region A1, the second sub-region A2, the third sub-region A3, and the fourth sub-region A4. Then there are four adjacent regions: the first adjacent region, the second adjacent region, the third adjacent region, and the fourth adjacent region. Among them, the first adjacent region includes the first sub-region A1 and the second sub-region A2; the second adjacent region includes the first sub-region A1 and the third sub-region A3; the third adjacent region includes the third sub-region A3 and the fourth sub-region A4; the fourth adjacent region includes the second sub-region A2 and the fourth sub-region A4.

[0126] Similarly, the region with the largest snow accumulation thickness among all adjacent regions is taken as the target adjacent region. Assume that the first adjacent region is the target region. Then the first adjacent region is heated, and the height of the third adjacent region is controlled to rise while the height of the first adjacent region is controlled to fall. That is, by adjusting the air suspension, the attitude of the front wheels of the vehicle is lowered, and the attitude of the rear wheels is raised.

[0127] After the snow in the first adjacent region is cleared, the vehicle is restored to the normal state. Then, the third adjacent region needs to be heated, and the height of the third adjacent region is controlled to fall while the height of the first adjacent region is controlled to rise. That is, by adjusting the air suspension, the attitude of the front wheels of the vehicle is raised, and the attitude of the rear wheels is lowered.

[0128] In this way, there are corresponding heating strategies and vehicle tilt control strategies for different snow positions, so that the snow on the roof can slide off quickly, improving the snow cleaning efficiency.

[0129] S112. Clear the snow on the roof according to the heating strategy and the vehicle tilt strategy, so that the snow slides off the roof.

[0130] After the heating strategy and the vehicle tilt strategy are determined, the snow on the roof is cleared according to the heating strategy and the vehicle tilt strategy, so that the snow slides off the roof. The specific cleaning method can refer to the above description and will not be elaborated here.

[0131] It should be noted that in this embodiment, the air suspension will be adjusted only when it is ensured that the vehicle is in a safe state. Then, before clearing the snow on the roof according to the heating strategy and the vehicle tilt strategy, the method further includes:
