Detailed Implementation

[0020] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0021] The following describes the vehicle, lower leg support system and control method thereof according to embodiments of the present application with reference to the accompanying drawings. First, the lower leg support system according to embodiments of the present application will be described with reference to the accompanying drawings.

[0022] Figure 1 This is a block diagram of a calf support system 10 according to an embodiment of this application.

[0023] like Figure 1 As shown, the lower leg support system 10 includes: an environmental sensing component 100, a main control component 200, a support control component 300, and an execution component 400.

[0024] The environmental perception component 100 is used to collect information about the vehicle's surrounding environment; the main control component 200 is used to generate collision warning information based on the surrounding environment information; the support control component 300 is used to generate target execution instructions based on the collision warning information; and the execution component 400 is used to execute corresponding actions based on the target execution instructions.

[0025] Among them, the vehicle's surrounding environment information refers to all perceived data on the state of objects and the road scene within the area surrounding the vehicle.

[0026] Specifically, the lower leg support system 10 proposed in this application embodiment is composed of an environmental perception component 100, a main control component 200, a support control component 300, and an execution component 400. The environmental perception component 100 is used to collect information about the vehicle's surrounding environment and provide basic data support for the main control decision. The main control component 200 analyzes and judges the collected surrounding environment information and generates corresponding collision warning information. The support control component 300 completes control logic calculation based on the generated collision warning information and outputs target execution instructions. The execution component 400 completes the corresponding actions based on the target execution instructions, thereby realizing the adaptive control and pedestrian protection functions of the lower leg support system.

[0027] Therefore, by detecting vehicle status and pedestrian status outside the vehicle, when a car collides head-on with a pedestrian, the control system can precisely control the operation of the pedestrian protection lower leg support system, change the lower leg support position in time, prevent the pedestrian's lower leg from being subjected to uneven impact force or the lower leg from being caught under the vehicle, and achieve the best pedestrian lower leg safety protection.

[0028] To help those skilled in the art to further understand the lower leg support system proposed in this application, a detailed description is provided below with reference to specific embodiments.

[0029] First, the environmental sensing component 100 of the embodiments of this application will be described in detail.

[0030] Optionally, in some embodiments, the environmental perception component 100 includes a radar sensing unit and a visual sensing unit, wherein the radar sensing unit is used to collect radar information about the vehicle's surroundings; and the visual sensing unit is used to collect visual information about the vehicle's surroundings.

[0031] Furthermore, in some embodiments, the radar sensing unit and the vision sensing unit are disposed inside the windshield of the vehicle.

[0032] Among them, the vehicle's surrounding radar information refers to radar perception data of targets and the road environment in the area surrounding the vehicle. The vehicle's surrounding visual information refers to image and visual feature data of the scene surrounding the vehicle.

[0033] Specifically, the environmental perception component 100 includes a radar sensing unit and a visual sensing unit. The radar sensing unit is installed outside the vehicle to collect radar information around the vehicle and send the radar information around the vehicle to the main control component 200 for algorithm calculation. The visual sensing unit is installed outside the vehicle to collect visual information around the vehicle and send the signal to the main control component 200 for algorithm calculation.

[0034] Furthermore, both the radar sensing unit and the vision sensing unit are installed on the inner side of the vehicle's windshield. This installation location is based on the fact that the windshield isolates the sensor units from complex environmental interference such as wind, sand, rain, snow, or direct sunlight, ensuring the stability and detection accuracy of the sensor units. At the same time, thanks to the unobstructed view in front of the windshield, radar detection data and visual scene information in front of and around the vehicle can be continuously and unimpededly collected.

[0035] Secondly, the landlord control component 200 in the embodiments of this application will be described in detail.

[0036] Optionally, in some embodiments, the main control component 200 includes: an identification unit, a generation unit, and an output unit, wherein the identification unit is used to identify the type of obstacle in front of the vehicle and the collision risk based on the surrounding environment information; the generation unit is used to generate collision warning information based on the type of obstacle in front and the collision risk; and the output unit is used to output the collision warning information to the support control component.

[0037] Optionally, in some embodiments, the generation unit includes: a first generation subunit, a second generation subunit, and a third generation subunit, wherein the first generation subunit is used to generate a first warning message as collision warning message when the obstacle ahead is not a pedestrian or cyclist; the second generation subunit is used to generate a second warning message as collision warning message when the obstacle ahead is a pedestrian or cyclist and the collision risk is an avoidable collision; and the third generation subunit is used to generate a third warning message as collision warning message when the obstacle ahead is a pedestrian or cyclist and the collision risk is an unavoidable collision, wherein the urgency level of the third warning message is higher than that of the second warning message.

[0038] The first, second, and third warning messages can be user-preset warning messages, warning messages obtained through a limited number of experiments, or warning messages obtained through a limited number of computer simulations.

[0039] Specifically, the main control component 200 can be an ADAS controller (Advanced Driver Assistance Systems), which receives information collected from the environmental perception component 100 and performs comprehensive algorithm analysis.

[0040] Furthermore, when the identification unit of the main control component 200 identifies the obstacle ahead as a non-pedestrian or non-cyclist based on the surrounding environment information, the first generation subunit generates a first warning message C1, which is then sent to the support control component 300 by the output unit. When the identification unit identifies the obstacle ahead as a pedestrian or cyclist based on the surrounding environment information and the collision can be avoided, the second generation subunit generates a second warning message C2, which is then sent to the support control component 300 by the output unit. When the identification unit identifies the obstacle ahead as a pedestrian or cyclist based on the surrounding environment information and the collision is unavoidable, the third generation subunit generates a third warning message C3, which is then sent to the support control component 300 by the output unit.

[0041] Furthermore, the support control component 300 of the embodiments of this application will be described in detail.

[0042] Optionally, in some embodiments, the support control component 300 includes: a first control unit and a second control unit, wherein the first control unit is used to execute a first position command as a target command when the collision warning information is a first warning information or a second warning information; and the second control unit is used to execute a second position command as a target command when the collision warning information is a first warning information or a second warning information.

[0043] The first position command and the second position command can be position commands preset by the user, position commands obtained through a limited number of experiments, or position commands obtained through a limited number of computer simulations.

[0044] Specifically, the support control component 300 receives warning information from the main control component 200 and performs algorithm analysis. When the support control component 300 receives the first warning information or the second warning information, the first control unit takes the first position command as the target execution command and sends the target execution command to the execution component 400; when the support control component 300 receives the third warning information, the second control unit takes the second position command as the target execution command and sends the target execution command to the execution component 400.

[0045] Finally, the execution component 400 of the embodiments of this application will be described in detail.

[0046] Optionally, in some embodiments, the execution component 400 includes: a first execution unit and a second execution unit, wherein the first execution unit is used to control the lower leg support system to be in a first position when the target execution instruction is a first position instruction; and the second execution unit is used to control the lower leg support system to be in a second position when the target execution instruction is a second position instruction.

[0047] The first position and the second position can be positions preset by the user, positions obtained through a limited number of experiments, or positions obtained through a limited number of computer simulations.

[0048] Specifically, the execution component 400 receives the target execution instruction from the support control component 300 and performs actions according to the instruction. The operating state of the execution component 400 can be configured into two or more modes according to the actual application scenario requirements. This embodiment adopts a dual-state configuration, where the first state is the initial installation position of the calf support system, and the second state is the working position of the calf support system's protective intervention. Further, when the target execution instruction received by the execution component 400 is the first position instruction, the execution component 400 controls the calf support system to be in the first position, i.e., the initial installation position; when the target execution instruction received by the execution component 400 is the second position instruction, the execution component 400 controls the calf support system to be in the second position, i.e., the working position.

[0049] To facilitate those skilled in the art to further understand the lower leg support system of the embodiments of this application, the following is combined with... Figure 2 and Figure 3 Further explanation is needed.

[0050] On the one hand, such as Figure 2 As shown, Figure 2This is a flowchart of a control method for a calf support system according to an embodiment of this application. The control method for the calf support system includes the following steps: S201, the external radar sensor collects radar information around the vehicle and executes step S203.

[0051] S202, the external vision sensor collects visual information about the vehicle's surroundings and executes step S203.

[0052] S203, the ADAS controller receives radar information and visual information around the vehicle and performs comprehensive algorithm analysis. When the obstacle in front is identified as not a pedestrian or cyclist, it sends a collision warning signal C1 to the lower leg support system controller; when the obstacle in front is identified as a pedestrian or cyclist and the collision can be avoided, it sends a collision warning signal C2 to the lower leg support system controller; when the obstacle in front is identified as a pedestrian or cyclist and the collision is unavoidable, it sends an emergency collision warning signal C3 to the lower leg support system controller.

[0053] S204, the lower leg support system controller receives the collision signal from the ADAS controller, performs algorithm analysis, and when it receives the C1 or C2 signal, it sends the execution instruction DF1 to the lower leg support system actuator; when it receives the C3 signal, it sends the execution instruction DF2 to the lower leg support system actuator.

[0054] S205, the lower leg support system actuator activates the protection function (e.g., a recoverable method such as a motor), extending the lower leg protection structure forward.

[0055] Therefore, the embodiments of this application use an ADAS system to detect the vehicle status in real time and adjust the working status of the support system as needed. During normal driving, the support system remains contracted to improve vehicle passability. When a collision occurs, the support system switches to an extended state to ensure that the pedestrian's lower leg is evenly stressed. This not only improves the protection effect of the pedestrian's lower leg in a frontal collision, but also solves the problem of the incompatibility between vehicle passability and lower leg protection.

[0056] On the other hand, such as Figure 3 As shown, Figure 3This is a schematic diagram of a calf support system according to an embodiment of this application. The calf support system may include: an environmental perception component 100, a main control component 200, a support control component 300, and an execution component 400. The environmental perception component 100 includes: an external radar sensor 1 (i.e., a radar sensing unit) and an external vision sensor 2 (i.e., a vision sensing unit), both mounted inside the windshield 6; an ADAS controller 200 (i.e., the main control component) and a calf support system controller 300 (i.e., the support control component) are deployed collaboratively as system control units; and a calf support system actuator 400 (execution component) is located inside the front bumper skin 7. The front bumper skin 7 provides a stable mounting platform and external protection for the actuator. A hood 8 is positioned above the front of the vehicle and adjacent to the front bumper skin 7, together forming the installation and extension space for the actuator, ensuring that the support structure can smoothly complete its extension and retraction movements. All components work together to constitute a complete adaptive pedestrian protection calf support hardware system.

[0057] According to the lower leg support system proposed in this application, the environmental perception component collects information about the vehicle's surrounding environment, the main control component generates collision warning information based on the surrounding environment information, the support control component generates a target execution command based on the collision warning information, and the execution component executes the corresponding action based on the target execution command. This solves the problem of achieving a coordinated balance between driving performance and safety protection in related technologies, and improves the protection effect on pedestrian lower legs.

[0058] Secondly, this application provides a vehicle that includes... Figure 1 The calf support system shown in the embodiment.

[0059] The vehicle proposed in the embodiments of this application solves the problem of failing to achieve a synergistic balance between driving performance and safety protection in related technologies through the aforementioned lower leg support system, thereby improving the protection effect of pedestrian lower legs.

[0060] Furthermore, a control method for a lower leg support system according to an embodiment of this application is described with reference to the accompanying drawings. This method is applied to... Figure 1 The calf support system shown in the embodiment.

[0061] Figure 4 This is a flowchart of a control method for a calf support system according to an embodiment of this application.

[0062] like Figure 4 As shown, the control method of this lower leg support system includes the following steps: S401 collects information about the vehicle's surrounding environment through environmental perception components; S402 generates collision warning information based on surrounding environmental information through the main control component; S403 generates target execution instructions based on collision warning information through the support control components; S404, the execution component performs the corresponding action according to the target execution instruction.

[0063] According to one embodiment of this application, environmental sensing components are used to collect information about the vehicle's surrounding environment, including: The vehicle's surrounding radar information is collected through the radar sensing unit; The vehicle's surrounding visual information is collected through a visual sensing unit.

[0064] It should be noted that the foregoing explanation of the lower leg support system embodiment also applies to the control method of the lower leg support system in this embodiment, and will not be repeated here.

[0065] According to the control method of the lower leg support system proposed in this application, the environmental perception component collects information about the vehicle's surrounding environment, the main control component generates collision warning information based on the surrounding environment information, the support control component generates a target execution command based on the collision warning information, and the execution component executes the corresponding action based on the target execution command.
