[0065] The following description of exemplary embodiments of the present disclosure is made in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding. These details should be considered as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0066] The following describes a method and apparatus for pedestrian protection, a vehicle, an electronic device, and a storage medium according to embodiments of the present disclosure with reference to the accompanying drawings.

[0067] Figure 1 A flowchart of a pedestrian protection method provided in an embodiment of the present disclosure.

[0068] like Figure 1 As shown, the method is applied to a vehicle's assisted driving system, and the method comprises the following steps:

[0069] Step 101: Acquire image data of a vehicle foreground and identify the image data.

[0070] In order to better understand the acquisition of the image data, Figure 2 As shown, Figure 2 A schematic top view of the front shape of a vehicle provided in an embodiment of the present application; Figure 2 The description is based on the example of a laser radar collecting image data of the foreground of a vehicle. However, it should be clear that this description is not intended to limit the collection device to only a laser radar, nor is it intended to limit the position of the laser radar. After the laser radar collects the image data of the foreground of the vehicle, the image data is transmitted to the Advanced Driving Assistance System (ADAS). The ADAS uses a computer vision algorithm to analyze and process the image data, thereby realizing the recognition of the image data. However, it should be clear that this description is not intended to limit the image data acquisition and recognition device to only ADAS, but can also be other devices that can recognize the image data. In addition, it is not intended to limit the recognition algorithm to a computer vision algorithm, but can also be other algorithms that can recognize the image data. The specific algorithm is no longer limited in this embodiment of the application.

[0071] When the recognition result includes the pedestrian, the process continues with step 102 . When the recognition result does not include the pedestrian, the process continues with step 101 .

[0072] Step 102 : When it is determined that the recognition result of the image data is a pedestrian, the braking distance between the vehicle and the pedestrian is calculated.

[0073] ADAS calibrates the lidar, determines the internal and external parameters of the lidar, locates the pedestrian in the image data through computer vision algorithms, and calculates the actual distance between the vehicle and the pedestrian based on the position of the pedestrian in the image and the calibration parameters of the lidar using the parallax method. Based on information such as the distance between the vehicle and the pedestrian, the vehicle speed, the vehicle braking ability, and the road conditions, the braking distance between the vehicle and the pedestrian is calculated using a preset vehicle kinematics algorithm.

[0074] It should be noted that the internal parameters of the laser radar refer to the parameters of the laser radar itself, including focal length, pixel size, principal point position, etc., which describe the geometric transformation relationship in the laser radar imaging process. The external parameters of the laser radar refer to the posture and position of the laser radar relative to the object, which describe the position and posture of the object in the laser radar coordinate system. The parallax method calculates the distance by analyzing the parallax generated when two viewpoints observe the same object. The preset vehicle kinematics algorithm describes the changes in the vehicle's position, speed, acceleration and other motion states during the movement process, which can be used to calculate the vehicle's braking distance. The above method for calculating the braking distance can also be used to calculate the braking distance in other ways, and the specific calculation method is not limited in this embodiment of the application.

[0075] When the braking distance includes pedestrians, step 103 is continued to be executed; when the recognition result does not include pedestrians, step 101 is continued to be executed.

[0076] Step 103 : If it is determined that the braking distance exceeds the preset safety distance, a control instruction is sent to a controller, so that the controller controls the detonator to detonate a preset target area of ​​the vehicle hood according to the control instruction.

[0077] Please continue reading Figure 2 The preset target area includes a hood hinge area and a hood lock area. The hood hinge and the hood lock fix the hood to the vehicle. The hood hinge area and the hood lock area vary with different vehicle models, that is, the positions of the hood hinge area and the hood lock area relative to the vehicle also vary.

[0078] When the ADAS determines that the braking distance exceeds the preset safety distance, it sends a detonation control instruction to the controller. After receiving the control instruction, the controller sends a detonation instruction to the detonator according to the control instruction. The detonator causes the explosive to explode, thereby detonating the hood hinge area and the hood lock area of ​​the vehicle hood.

[0079] It should be noted that the preset safety distance is not a fixed value and can be set according to actual conditions, such as the distance of two vehicle body lengths. The detonator consists of an electronic control device and an ignition head. The ignition head is an electronic component that can generate high temperature and is usually made of metals such as platinum, tungsten or aluminum. It can generate temperatures of up to several thousand degrees, thereby igniting explosives. Explosives are devices that can generate impact energy, such as dynamite. However, it should be clear that this description method does not limit the detonation method and equipment to the preset target area of ​​the vehicle hood.

[0080] The pedestrian protection method provided by the present disclosure obtains image data of the foreground of a vehicle and identifies the image data; when the image data is determined to be a pedestrian, the braking distance between the vehicle and the pedestrian is calculated; if the braking distance is determined to exceed a preset safety distance, a control instruction is sent to a controller, so that the controller controls the detonator to detonate a preset target area of ​​the vehicle hood according to the control instruction. Compared with the related art, the embodiment of the present application obtains image data of the foreground of the vehicle and identifies it while the vehicle is in motion. When it is determined that the braking distance exceeds a preset safety distance, a control instruction is sent to the controller, which controls the detonator to detonate a preset target area of ​​the vehicle hood, so that the vehicle hood is pre-raised before a collision with the pedestrian occurs, reducing damage to the pedestrian.

[0081] As a refinement of step 103, when executing the sending of the control instruction to the controller, it can be implemented in the following manner but is not limited to: Figure 3 As shown, Figure 3 A flowchart of a method for sending a control instruction to a controller provided in an embodiment of the present application includes:

[0082] Step 201: Obtain the synthetic acceleration of the pedestrian's head center of mass.

[0083] The vehicle's on-board inertial sensor collects pedestrian head data and calculates the composite acceleration of the pedestrian's head center of mass. The on-board inertial sensor transmits the composite acceleration of the pedestrian's head center of mass to the ADAS. It should be noted that the on-board inertial sensor is a sensor that measures acceleration and angular velocity, but it should be clear that this description is not intended to limit the device for measuring the composite acceleration of the pedestrian's head center of mass to only the on-board inertial sensor, nor is it a limitation on the location of the on-board inertial sensor.

[0084] When the ADAS obtains the synthetic acceleration of the pedestrian's head center of mass, step 202 is continued.

[0085] Step 202 : Calling a preset algorithm to calculate a head injury index based on the resultant acceleration of the pedestrian's head center of mass and any two moments during the collision process.

[0086] The formula corresponding to the preset algorithm is:

[0087]

[0088] Where a(t) is the resultant acceleration of the pedestrian's head center of mass, t1 and t2 are any two moments during the collision between the vehicle and the pedestrian, and t2-t1<15ms;

[0089] It should be noted that HIC (Head Injury Criterion) is an indicator used to measure the severity of head injury to pedestrians caused by vehicle collisions, but it should be clear that this description method is not limited to the formula used in the preset algorithm.

[0090] After ADAS completes calculating the head injury index, it proceeds to step 203 .

[0091] Step 203 : determining the target vehicle hood lift height based on the mapping relationship between the head injury index and the vehicle hood lift height.

[0092] The mapping relationship between the head injury index and the vehicle hood lift height is pre-configured. The head injury index is positively correlated with the vehicle hood lift height. That is, the larger the head injury index, the higher the corresponding vehicle hood lift height, and the smaller the head injury index, the lower the corresponding vehicle hood lift height.

[0093] The height at which the vehicle hood is lifted can be flexibly configured according to different vehicle models, and is not specifically limited in the embodiments of this application.

[0094] In order to better understand the target vehicle hood, Figure 4 As shown, Figure 4 A schematic diagram of the vehicle hood damage value division area provided in an embodiment of the present application;

[0095] According to the collision protection requirements for pedestrians in GB / T 24550-2009, when a pedestrian collides with a vehicle, the head area with a head injury index value of 1700 or above cannot exceed one-third of the pedestrian's head area. Due to the height difference between adult pedestrians and child pedestrians, the area of ​​the hood that they impact after colliding with the vehicle is also different. Therefore, the area is divided into adult head impact area and child head impact area. ADAS calculates the target vehicle hood lift height based on the mapping relationship between the head injury index and the vehicle hood lift height.

[0096] When the ADAS determines that the hood of the target vehicle is raised, the process proceeds to step 204 .

[0097] Step 204: Send a control instruction to the controller, wherein the control instruction carries the target vehicle hood lifting height.

[0098] The target vehicle hood lifting height is carried in the control instruction so that the controller can parse the control instruction, obtain the target vehicle hood lifting height, and control the detonator to lift the vehicle hood to the target vehicle hood lifting height.

[0099] In actual applications, the image data may not only contain pedestrians, but also non-pedestrians such as animals and obstacles. In related technologies, when a vehicle collides with a non-pedestrian, the vehicle hood may be falsely triggered and exploded, thereby increasing the vehicle's maintenance costs. In order to solve the problem of maintenance costs caused by false triggering, the embodiment of the present application continues to obtain the vehicle foreground when it is determined that the recognition result of the image data is a non-pedestrian, rather than directly sending a control instruction to the controller without analyzing the image data, so as to prevent false triggering.

[0100] As a refinement of step 101, when executing the acquisition of image data of the vehicle foreground, it can be implemented by but not limited to the following methods, including at least one of a vehicle camera, a non-vehicle camera connected to the vehicle, a millimeter wave radar, and a lidar.

[0101] Figure 5 A flowchart of a pedestrian protection method provided in an embodiment of the present disclosure.

[0102] like Figure 5 As shown, the method is applied to a vehicle controller (Airbag Control Unit, ACU), and the method includes the following steps:

[0103] Step 301: Receive a control instruction sent by the vehicle's auxiliary driving system.

[0104] The ACU receives a control instruction sent by the ADAS, which carries the target vehicle hood lifting height, and prepares for controlling the detonator to detonate a preset target area of ​​the vehicle hood according to the control instruction.

[0105] Step 302: Control the detonator to detonate a preset target area of ​​the vehicle hood according to the control instruction.

[0106] The ACU controls the detonator to detonate the hood hinge area and the hood lock area of ​​the vehicle hood according to the control instruction, thereby lifting the hood of the target vehicle.

[0107] The pedestrian protection method provided by the present disclosure obtains image data of the foreground of a vehicle and identifies the image data; when the image data is determined to be a pedestrian, the braking distance between the vehicle and the pedestrian is calculated; if the braking distance is determined to exceed a preset safety distance, a control instruction is sent to a controller, so that the controller controls the detonator to detonate a preset target area of ​​the vehicle hood according to the control instruction. Compared with the related art, the embodiment of the present application obtains image data of the foreground of the vehicle and identifies it while the vehicle is in motion. When it is determined that the braking distance exceeds a preset safety distance, a control instruction is sent to the controller, which controls the detonator to detonate a preset target area of ​​the vehicle hood, so that the vehicle hood is pre-raised before a collision with the pedestrian occurs, reducing damage to the pedestrian.

[0108] As a refinement of step 302, when controlling the detonator to detonate the preset target area of ​​the vehicle hood according to the control instruction, it can be implemented in the following manners, but not limited to:

[0109] The ACU parses the control instruction to obtain the target vehicle hood lifting height, and then causes the detonator to detonate a preset target area of ​​the vehicle hood to the target vehicle hood lifting height.

[0110] As a refinement of the above-mentioned embodiment, when controlling the detonator to detonate the preset target area of ​​the vehicle hood to the target vehicle hood lifting height, the following methods may be used, but are not limited to:

[0111] Based on the mapping relationship between the vehicle hood lifting height and the amount of explosives used, the detonator is controlled to detonate a preset target area of ​​the vehicle hood to the target vehicle hood lifting height.

[0112] The mapping relationship between the amount of explosives and the height to which the vehicle hood is lifted is pre-configured. The amount of explosives is positively correlated with the height to which the vehicle hood is lifted. That is, the more explosives are detonated, the higher the corresponding vehicle hood is lifted, and the smaller the amount of explosives are detonated, the lower the corresponding vehicle hood is lifted.

[0113] The height at which the vehicle hood is lifted can be flexibly configured according to different vehicle models, and is not specifically limited in the embodiments of this application.
