[0043] Automakers' dissemination of automotive safety knowledge is mostly limited to vehicle collision safety performance, with little attention paid to pedestrian protection. With the emergence of numerous intelligent automotive technologies, pedestrians, as a vulnerable group, are easily injured in collisions with vehicles. Pedestrian safety in complex environments with mixed pedestrian and vehicle traffic has always been a crucial area of ​​vehicle development, and significantly improving the safety of both vehicles and pedestrians is a pressing issue that needs to be addressed. Pedestrian protection primarily focuses on protecting the pedestrian's head, thighs, lower legs, and knees. When a vehicle collides with a pedestrian, the vehicle body usually makes direct contact, with the front bumper often contacting the pedestrian, causing injury.

[0044] In view of this, the present invention proposes a front bumper assembly 100. Figures 1 to 3 This is an embodiment of the front bumper component 100 provided by the present invention. The front bumper component will be described below with reference to the specific drawings.

[0045] Reference Figures 1 to 3 The front bumper assembly 100 includes a front bumper 1 and a drive unit 2. The front bumper 1 includes a soft front bumper 11 and a hard front bumper 12. The soft front bumper 11 and the hard front bumper 12 are used to be installed on the front side of the vehicle body. At least one of the soft front bumper 11 and the hard front bumper 12 is movably configured such that the front bumper 1 has a first state with the soft front bumper 11 facing forward and a second state with the hard front bumper 12 facing forward. The drive unit 2 drives the front bumper 1 to move to the first state or the second state.

[0046] In the technical solution of this invention, the front bumper 1 has a first state in which the soft front bumper 11 faces forward and a second state in which the hard front bumper 12 faces forward. When the front bumper 1 is in the first state, the soft front bumper 11 faces forward. Because the soft front bumper 11 has low hardness, high wind resistance, and good cushioning, when a car collides with a pedestrian, the vehicle contacts the pedestrian or other obstacles through the soft front bumper 11, reducing the impact force and avoiding a hard collision between the vehicle body and the pedestrian or other obstacles, effectively reducing the risk of pedestrian death or injury. Furthermore, because the vehicle collides with the outside through the soft front bumper 11, the impact force on the vehicle body is reduced through flexible collision, mitigating the injury or death of occupants, effectively reducing the danger of collisions during driving, and reducing vehicle damage. The front bumper 1 has low cost, good effect, simple structure, and strong applicability. When the front bumper 1 switches to the second state, the hard front bumper 12 faces forward. The hard front bumper 12 has high hardness, low wind resistance, and an attractive appearance.

[0047] To allow the front bumper 1 to switch between the first and second states, the specific structure of the front bumper 1 is not limited. In this embodiment, the front bumper 1 further includes a mounting body 13. The mounting body 13 extends in the left-right direction and is rotatably mounted on the front side of the vehicle body around the left-right extending axis. The soft front bumper 11 and the hard front bumper 12 are respectively disposed on the periphery of the mounting body 13. The driving device 2 includes a motor 21 and a drive shaft 22 extending in the left-right direction. The motor 21 drives the drive shaft 22 to rotate. The drive shaft 22 is connected to the mounting body 13 so as to drive the mounting body 13 to rotate under the drive of the motor 21. Through the rotation of the mounting body 13, the soft front bumper 11 and the hard front bumper 12 are rotated back and forth. In this embodiment, the soft front bumper 11 and the hard front bumper 12 are simultaneously activated. In one embodiment, the soft front bumper 11 can also be activated. There are various activation methods. Specifically, when the front bumper 1 is in the second state, the hard front bumper 12 faces forward. When the front bumper 1 needs to switch to the first state, the soft front bumper 11 moves to the front of the hard front bumper 12 to achieve the first state where the soft front bumper 11 faces forward. When the front bumper 1 needs to switch to the second state, the front bumper 1 moves away from the front of the hard front bumper 12 to achieve the second state where the hard front bumper 12 faces forward. In another embodiment, the hard front bumper 12 can also be activated. There are various activation methods, and no specific limitation is imposed.

[0048] The present invention also proposes a vehicle 200, Figure 4 In one embodiment of the vehicle 200 provided by the present invention, the vehicle 200 includes a control device and the front bumper assembly 100.

After the step of obtaining the driving information of the vehicle 200, the following is also included:

[0061] When the driving state is an unmanned driving state, the transmission is controlled to decelerate to a preset speed.

[0062] The present invention also proposes a control method for vehicle 200. Figure 5 This is an embodiment of the vehicle 200 control method provided by the present invention. Figure 6 Please refer to another embodiment of the vehicle 200 control method provided by the present invention. Figures 1 to 4 The vehicle 200 includes a front bumper assembly 100 and a control device. The front bumper assembly 100 includes a front bumper 1 and a drive device 2. The front bumper 1 includes a soft front bumper 11 and a hard front bumper 12. The soft front bumper 11 and the hard front bumper 12 are mounted on the front side of the vehicle body. At least one of the soft front bumper 11 and the hard front bumper 12 is movably configured such that the front bumper 1 has a first state with the soft front bumper 11 facing forward and a second state with the hard front bumper 12 facing forward. The drive device 2 is driven by the front bumper 1 to drive the front bumper to move to the first state or the second state. The control device is electrically connected to the drive device 2. The control method of the vehicle 200 includes the following steps:

[0063] S10. Obtain the driving information of the vehicle 200.

[0064] Specifically, the driving information can be of various types. The driving information may include driving status, which includes unmanned driving status and manned driving status.

[0065] S20. Control the drive unit 2 to drive the front bumper 1 to move according to the driving information.

[0066] Based on the specific driving information, the front bumper 1 is controlled to move. When the front bumper 1 is controlled to move to the first state where the soft front bumper 11 faces forward, the soft front bumper 11 has low rigidity, high wind resistance, and good cushioning, which can effectively reduce the danger of a collision. When a car collides with a pedestrian, the vehicle 200 reduces the impact force by contacting the pedestrian or other obstacles through the soft front bumper 11, avoiding a hard collision between the vehicle body and the pedestrian or other obstacles, effectively reducing the risk of pedestrian death or injury. Furthermore, because the vehicle 200 collides with the outside through the soft front bumper 11, the impact force on the vehicle body is reduced through flexible collision, mitigating the injury or death of occupants, effectively reducing the danger of a collision and minimizing vehicle damage. When the front bumper 1 is controlled to move to the second state where the hard front bumper 12 faces forward, the hard front bumper 12 has high rigidity, low wind resistance, and an attractive appearance.

[0067] With the emergence of various intelligent automotive technologies, the driving information includes the driving state, which includes both driverless and driver-driven states. In the driverless state, to improve pedestrian safety, step S20 includes:

[0068] Step S21: When the driving state is an unmanned driving state, control the drive device 2 to drive the front bumper 1 to move to the first state;

[0069] Step S22: When the driving state is a manned driving state, control the drive device 2 to drive the front bumper 1 to the second state.

[0070] Specifically, in this embodiment, the front bumper 1 includes the mounting body 13, which extends in a left-right direction and is rotatably mounted on the front side of the vehicle body around the left-right extending axis. The soft front bumper 11 and the hard front bumper 12 are respectively disposed on the periphery of the mounting body 13. The driving device 2 includes the motor 21 and the driving shaft 22 extending in a left-right direction. The motor 21 drives the driving shaft 22 to rotate, and the driving shaft 22 is connected to the mounting body 13 so that the mounting body 13 rotates under the drive of the motor 21. Through the rotation of the mounting body 13, the soft front bumper 11 and the hard front bumper 12 are rotated back and forth. When the driving state is an unmanned driving state, the motor 21 of the driving device 2 is controlled to drive the driving shaft 22 to rotate, thereby driving the mounting body 13 to rotate back and forth, and rotate until the soft front bumper 11 faces forward. When the driving state is a manned driving state, the driving device 2 is controlled to drive the mounting body 13 to rotate until the hard front bumper 12 faces forward.

[0071] In one embodiment of the present invention, the vehicle 200 further includes an identification device for identifying the driving information of the vehicle 200. The control device is electrically connected to the identification device. When the identification device is present, step S10 includes:

[0072] The driving information identified by the identification device is obtained.

[0073] Specifically, depending on the specific settings of the identification device, the identified driving information varies. In one embodiment, the identification device includes a human body sensor, which is not limited and can be an infrared sensor. When the identification device detects that a pedestrian is approaching the vehicle within a preset distance of 200, step S20 includes:

[0074] The drive device 2 is controlled to drive the front bumper 1 to the first state.

[0075] Depending on the different functions of the identification device, the identification device can identify various types of driving information, and there is no specific limitation. The specific steps of step S20 will vary depending on the different types of driving information.

[0076] In one embodiment of the present invention, the vehicle 200 further includes a transmission, the control device is electrically connected to the transmission, the driving information includes a driving state, the driving state includes an unmanned driving state and a manned driving state, and the following is included after step S10:

[0077] Step S30: When the driving state is an unmanned driving state, control the transmission to decelerate to a preset speed.

[0078] Specifically, to improve driving and pedestrian safety, when the driving state is unmanned, the transmission is controlled to decelerate. The preset speed is not limited and can be changed based on specific driving information. For example, the driving information includes the driving environment; the preset speed for sunny weather can be set higher than the preset speed for rainy and / or foggy weather. The driving information also includes pedestrian traffic outside the vehicle; the preset speed when pedestrian traffic outside the vehicle is greater than a preset pedestrian traffic level is lower than the preset speed when pedestrian traffic outside the vehicle is less than a preset pedestrian traffic level. The specific settings are not limited and are based on improving the safety of the vehicle and pedestrians, and are determined according to actual needs.
