[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0046] See also Figures 1 to 5 The present invention provides a vehicle suspension control system, which can be applied to a vehicle to improve the passive safety of the vehicle by adjusting the height of the vehicle when a collision occurs. The vehicle suspension control system 100 may include but is not limited to an air spring 110, an information acquisition unit 120, a control unit 130, and a suspension actuator unit 140. The air spring 110 may be arranged between the vehicle wheel and the vehicle frame to achieve support and buffering of the vehicle.
[0047] See also Figure 1 The information collection unit 120 can be arranged on the car to collect environmental information within a preset range of the car and the car's own status information. The information collection unit 120 may include but is not limited to an environmental collection subunit 121 and a sensor unit 122. There may be multiple environmental collection subunits 121 to collect environmental information within a preset range of the car. The environmental collection subunit 121 can be a surround-view camera or other types of information collection elements, as long as it can collect environmental information within a preset range of the car. For example, two environmental collection subunits 121 can be arranged, and both of the two environmental collection subunits 121 can be surround-view cameras, and are respectively arranged on the front and rear sides of the car body to facilitate the collection of environmental information within a preset range of the car.
[0048] See also Figure 1 Furthermore, the environmental information within the preset range of the car may include all obstacle information within a circular area with a radius of 5m to 8m with the car as the center point. For example, the environmental information may be all obstacle information within a circular area with a radius of 5m with the car as the center point, or all obstacle information within a circular area with a radius of 8m. However, it is not limited to this, and may also be all obstacle information within a circular area with a radius of 6m with the car as the center point. Obstacle information may be vehicle information, pedestrian information, or other obstacle information, that is, any object that can hinder the normal and safe driving of the car can be defined as obstacle information.
[0049] See also Figure 1 Furthermore, the sensing unit 122 can be used to obtain the vehicle's own state information, and the vehicle's own state information can include vehicle wheel speed information, vehicle steering information, vehicle height information, and vehicle acceleration information. However, it is not limited thereto, and other information can also be included. The sensing unit 122 can include a wheel speed sensor, a steering sensor, a distance sensor, and an acceleration sensor, which are respectively used to obtain corresponding vehicle wheel speed information, vehicle steering information, vehicle height information, and vehicle acceleration information.
[0050] See also Figure 1 , the control unit 130 can be arranged in the car, and the control unit 130 can be communicatively connected to the information collection unit 120 to generate collision risk information based on the comparison result of the environmental information and the preset collision condition. However, it is not limited to this. The control unit 130 can also generate spring control information based on the comparison result of the collision risk information and its own state information. Specifically, the control unit 130 may include a driving control unit 131 and a suspension control unit 132. The driving control unit 131 can be communicatively connected to the information collection unit 120 to perform vehicle identification processing on the environmental information to generate neighboring vehicle information. However, it is not limited to this. The driving control unit 131 can also determine whether the neighboring vehicle information meets the preset collision condition to generate collision risk information. Among them, the preset collision condition can be that the straight line where the driving direction information in the neighboring vehicle information is located intersects with the straight line where the driving direction information of the car is located, the speed information in the neighboring vehicle information is greater than or equal to the preset speed, and the distance between the neighboring vehicle and the car is less than or equal to the preset distance.
[0051] See also Figure 1, further, the preset speed in the preset collision condition can be greater than or equal to 30 kilometers per hour. For example, the preset speed can be 30 kilometers per hour, or 50 kilometers per hour. The preset distance can be between 1 meter and 3 meters, for example, the preset distance can be 1 meter, or 3 meters. However, it is not limited to this, and the preset distance can also be 2 meters. That is, when the straight line where the driving direction information in the neighboring vehicle information is located intersects with the straight line where the driving direction information of the car is located, its speed information is greater than or equal to the preset speed, and its distance from the car is less than or equal to the preset distance, the driving control unit 131 can determine that the neighboring vehicle can collide with the car and generate collision risk information.
[0052] See also Figure 1 Furthermore, the collision risk information may include collision position information, collision height information, and collision degree information. The collision position information may be generated based on the driving direction information in the neighboring vehicle information. The collision height information may be generated based on the body information in the neighboring vehicle information. The collision degree information may be generated based on the speed information and distance information analysis in the neighboring vehicle information.
[0053] See also Figure 1 , the suspension control unit 132 can be communicatively connected to the driving control unit 131 to generate spring control information based on the comparison result of the collision risk information and its own state information. That is, the suspension control unit 132 can determine whether it is necessary to achieve passive safety defense by controlling the air spring 110 by comparing the collision position information, collision height information and collision degree information with its own state information. For example, the suspension control unit 132 controls the air spring 110 away from the collision area to deflate so as to reduce the height of the vehicle suspension in the side area. The suspension control unit 132 controls the air spring 110 close to the collision area to inflate so as to increase the height of the vehicle suspension in the side area, thereby alleviating the impact force caused by the collision and reducing the damage caused to the driver and passengers in the car due to the collision.
[0054] See also Figure 1It is worth further explaining that the spring control information includes spring inflation information and spring deflation information. Among them, the spring inflation information is characterized by the fact that when the air spring 110 is inflated, the height of the air spring 110 is within the range of 10mm to 70mm, and the spring deflation information is characterized by the fact that when the air spring 110 is deflated, the height of the air spring 110 is within the range of 40mm to 70mm. In addition, the spring inflation information and the spring deflation information depend on the collision risk information. For example, when the collision position information in the collision risk information is a relatively weak structural position in the car, or the collision height information is a relatively low position in the car, or the collision degree information is a relatively strong collision degree, the spring deflation information and the spring inflation information can both be the maximum value to achieve a better anti-collision effect. However, it is not limited to this. When the collision position information in the collision risk information is a relatively strong structural position in the car, or the collision height information is a relatively rear position in the car, or the collision degree information is a relatively weak collision degree, the spring deflation information and the spring inflation information can both be the minimum value to achieve the anti-collision effect.
[0055] See also Figure 1 The suspension actuator unit 140 can be communicatively connected to the suspension control unit 132, and the suspension actuator unit 140 can also be connected to the air spring 110, so as to inflate the air spring 110 close to the collision area of the car according to the spring control information, and to deflate the air spring 110 far from the collision area. Specifically, the suspension actuator unit 140 can be an air pump to realize the inflation or deflation of the air spring 110. There can be multiple suspension actuator units 140, that is, one side of each air spring 110 can be provided with a suspension actuator unit 140. However, it is not limited to this, and multiple suspension actuator units 140 can also be provided on one side of each air spring 110, so as to achieve faster and better inflation or deflation effects, and further enhance the anti-collision effect.
[0056] See also Figures 2 to 5 The present invention also provides a vehicle suspension control method, which may correspond to the vehicle suspension control system 100 in the above embodiment. The method includes steps S210 to S240, which are described in detail as follows:
[0057] Step S210: Collect environmental information within a preset range of the car and the car's own state information.
[0058] Step S220: Generate collision risk information based on the comparison result between the environmental information and the preset collision condition.
[0059] Step S230: Generate spring control information based on the comparison result between the collision risk information and the self-state information.
[0060] Step S240: Inflate the air springs on the vehicle close to the collision area according to the spring control information, and deflate the air springs away from the collision area, so as to complete the control of the vehicle suspension.
[0061] In one embodiment of the present invention, when step S210 is executed, specifically, environmental information within a preset range of the car and the car's own state information can be collected and acquired through the information collection unit 120. The information collection unit 120 can be provided on the car, and the information collection unit 120 can include but is not limited to an environmental collection subunit 121 and a sensor unit 122. There can be multiple environmental collection subunits 121 to collect environmental information within a preset range of the car. The environmental collection subunit 121 can be a surround-view camera or other types of information collection elements, as long as it can collect environmental information within a preset range of the car. For example, two environmental collection subunits 121 can be provided, and both of the two environmental collection subunits 121 can be surround-view cameras, and are respectively provided on the front and rear sides of the car body to facilitate the collection of environmental information within the preset range of the car.
[0062] Further, the environmental information within the preset range of the car may include all obstacle information within a circular area with a radius of 5m to 8m with the car as the center point. For example, the environmental information may be all obstacle information within a circular area with a radius of 5m with the car as the center point, or may be all obstacle information within a circular area with a radius of 8m. However, it is not limited to this, and it may also be all obstacle information within a circular area with a radius of 6m with the car as the center point. The obstacle information may be vehicle information, pedestrian information, or other obstacle information, that is, any object that can hinder the normal and safe driving of the car may be defined as obstacle information. The sensing unit 122 may be used to obtain the car's own state information, and the car's own state information may include the car's wheel speed information, the car's steering information, the car's height information, and the car's acceleration information. However, it is not limited to this, and it may also include other information. The sensing unit 122 may include a wheel speed sensor, a steering sensor, a distance sensor, and an acceleration sensor, which are respectively used to obtain the corresponding car's wheel speed information, car's steering information, car's height information, and car's acceleration information.
[0063] See also Figure 3 and Figure 5 In one embodiment of the present invention, when executing step S220 to generate collision risk information based on the comparison result between the environmental information and the preset collision condition, step S220 may include the following steps:
[0064] Step S221: Perform vehicle identification processing on the environmental information to generate neighborhood vehicle information.
[0065] Step S222: determine whether the neighborhood vehicle information meets the preset collision condition.
[0066] Step S223: If the neighborhood vehicle information meets the preset collision condition, collision risk information is generated.
[0067] Step S224: If the neighboring vehicle information does not meet the preset collision condition, the judgment is repeated until the neighboring vehicle information meets the preset collision condition.
[0068] In one embodiment of the present invention, when step S221 is executed, specifically, vehicle identification processing of environmental information can be implemented by the driving control unit 131. Neighboring vehicle information may include driving direction information, speed information, location information, height information, length information, and distance information of neighboring vehicles.
[0069] In one embodiment of the present invention, when executing step S222, specifically, the driving control unit 131 can be used to determine whether the neighboring vehicle information meets the preset collision condition. The preset collision condition can be that the straight line where the driving direction information in the neighboring vehicle information is located intersects with the straight line where the driving direction information of the car is located, the speed information in the neighboring vehicle information is greater than or equal to the preset speed, and the distance between the neighboring vehicle and the car is less than or equal to the preset distance. Further, the preset speed in the preset collision condition can be greater than or equal to 30 kilometers per hour. For example, the preset speed can be 30 kilometers per hour, or 50 kilometers per hour. The preset distance can be between 1 meter and 3 meters, for example, the preset distance can be 1 meter, or 3 meters. However, it is not limited to this, and the preset distance can also be 2 meters.
[0070] In one embodiment of the present invention, when executing step S223, specifically, when the straight line containing the driving direction information in the neighborhood vehicle information intersects with the straight line containing the driving direction information of the car, its speed information is greater than or equal to the preset speed, and its distance from the car is less than or equal to the preset distance, the driving control unit 131 can determine that the neighborhood vehicle information meets the preset collision condition and generate collision risk information. Further, the collision risk information may include collision position information, collision height information, and collision degree information. The collision position information can be generated based on the driving direction information in the neighborhood vehicle information. The collision height information can be generated based on the body information in the neighborhood vehicle information. The collision degree information can be generated based on the speed information and distance information analysis in the neighborhood vehicle information.
[0071] In one embodiment of the present invention, when step S224 is executed, specifically, when the straight line containing the driving direction information in the neighboring vehicle information intersects with the straight line containing the driving direction information of the car, the speed information in the neighboring vehicle information is greater than or equal to the preset speed, and the distance between the neighboring vehicle and the car is less than or equal to the preset distance, when at least one of the three is not true, it is judged that the neighboring vehicle information does not meet the preset collision condition.
[0072] See also Figure 4 and Figure 5 In one embodiment of the present invention, when executing step S230, spring control information is generated based on the comparison result between the collision risk information and the self-state information, step S230 may include the following steps:
[0073] Step S231: Determine whether the own state information satisfies the collision risk information.
[0074] Step S232: if the self-state information does not satisfy the collision risk information, generating the spring control information;
[0075] Step S233: If the self-state information satisfies the collision risk information, the judgment is repeated until the self-state information does not satisfy the collision risk information, and the spring control information is generated.
[0076] In one embodiment of the present invention, when executing step S231, specifically, whether the self-state information satisfies the collision risk information can be judged by the suspension control unit 132. That is, the suspension control unit 132 can determine whether it is necessary to control the air spring 110 to achieve passive safety defense by comparing the collision position information, collision height information and collision degree information with the self-state information. For example, the suspension control unit 132 controls the air spring 110 away from the collision area to deflate so as to reduce the height of the car suspension in the side area. The suspension control unit 132 controls the air spring 110 close to the collision area to inflate so as to increase the height of the car suspension in the side area, thereby alleviating the impact force caused by the collision and reducing the damage caused to the driver and passengers in the car due to the collision.
[0077] In one embodiment of the present invention, when executing step S232 and step S233, specifically, the spring control information includes spring inflation information and spring deflation information. Among them, the spring inflation information is characterized by the fact that when the air spring 110 is inflated, the height of the air spring 110 is within the range of 10mm to 70mm, and the spring deflation information is characterized by the fact that when the air spring 110 is deflated, the height of the air spring 110 is within the range of 40mm to 70mm. In addition, the spring inflation information and the spring deflation information depend on the collision risk information. For example, when the collision position information in the collision risk information is a relatively weak structural position in the car, or the collision height information is a relatively low position in the car, or the collision degree information is a relatively strong collision degree, the spring deflation information and the spring inflation information can both be the maximum value to achieve the best anti-collision effect. However, it is not limited to this. When the collision position information in the collision risk information is a relatively strong structural position in the car, or the collision height information is a relatively rear position in the car, or the collision degree information is a relatively weak collision degree, the spring deflation information and the spring inflation information can both be the minimum value to achieve the best anti-collision effect.
[0078] See also Figure 1 , Figure 2 and Figure 5 In one embodiment of the present invention, when executing step S240, the air spring 110 close to the collision area of the car is inflated according to the spring control information, and the air spring 110 far from the collision area is deflated to complete the control of the car suspension. Specifically, the air spring 110 close to the collision area of the car is inflated according to the spring control information, and the air spring 110 far from the collision area is deflated by the suspension actuator 140. The suspension actuator 140 can be connected to the suspension control unit 132 for communication, and the suspension actuator 140 can also be connected to the air spring 110. The suspension actuator 140 can be an air pump to realize the inflation or deflation of the air spring 110. There can be multiple suspension actuators 140, that is, one side of each air spring 110 can be provided with a suspension actuator 140. However, it is not limited to this, and one side of each air spring 110 can also be provided with multiple suspension actuators 140, so as to achieve faster and better inflation or deflation effects, and further improve the anti-collision effect.
[0079] See also Figure 1 , Figure 2 and Figure 5The present invention also provides a car, the car 300 may include but is not limited to a car suspension control system 100, and the car suspension control system 100 is provided with at least one for controlling the air spring 110 of the car 300. Specifically, when the car 300 is working, the car suspension control system 100 is in a normal working state. The air spring 110 is in a normal inflation state to achieve shock absorption and buffering of the car 300. The information acquisition unit 120 collects environmental information within a preset range of the car 300 and the self-state information of the car 300, and uploads them to the driving control unit 131. The driving control unit 131 can perform vehicle identification processing on the environmental information to obtain neighboring vehicle information. Then, it is determined whether the neighboring vehicle information meets the preset collision condition. When the neighboring vehicle information meets the preset collision condition, the driving control unit 131 can generate collision risk information and upload it to the suspension control unit 132. When the neighboring vehicle information does not meet the preset collision condition, the driving control unit 131 continues to perform vehicle identification processing on the environmental information obtained by the information acquisition unit 120 to obtain real-time neighboring vehicle information. Then continue to judge whether the neighboring vehicle information meets the preset collision condition until the neighboring vehicle information meets the preset collision condition to generate collision risk information.
[0080] Subsequently, the suspension control unit 132 determines whether its own state information satisfies the collision risk information. When the self-state information of the automobile 300 satisfies the collision risk information, the suspension control unit 132 does not generate spring control information. When the self-state information of the automobile 300 does not satisfy the collision risk information, the suspension control unit 132 generates spring control information and controls the suspension actuator 140 through the spring control information. The suspension control unit 132 controls the suspension actuator 140 to inflate the nearby air spring 110 by sending spring inflation information to the suspension actuator 140 close to the collision area of the automobile 300. The suspension control unit 132 controls the suspension actuator 140 to deflate the nearby air spring 110 by sending spring deflation information to the suspension actuator 140 far from the collision area of the automobile 300, thereby further raising the height of the collision area of the automobile 300 to achieve a better anti-collision effect.
[0081] In summary, the automobile suspension control system, method and automobile provided by the present invention can lower the side of the automobile suspension away from the collision area and raise the side close to the collision area when the automobile is about to collide, so that the side beam of the raised side of the automobile can hit the obstacle, thereby improving the passive safety of the automobile and reducing the damage to the occupants when the vehicle collides.
