Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of vehicle control, in particular, to a vehicle safety control method and device, a storage medium and an electronic device. BACKGROUND

[0002] With the continuous increase of vehicle ownership in China, in order to ensure the safety of passengers on the vehicle when the vehicle collides, safety restraint devices such as seat belts and airbags are usually provided on the vehicle. In related technologies, the airbag is mainly ignited by the airbag controller using an ignition algorithm. After the vehicle collides, based on the acceleration signal of the vehicle, the airbag is ignited at the appropriate time to form a buffer area between the human body and the vehicle, thereby reducing the harm to the passengers when the vehicle collides.

[0003] However, such an ignition strategy is only applicable to scenarios where the driving posture and seating posture of the passenger are in a normal state (at this time, the distance between the human body parts such as the head and chest of the passenger and the objects in the vehicle is fixed). In actual situations, due to inertia such as emergency braking, the driving posture and seating posture of the passenger may not be in a normal state before the vehicle collides. At this time, if such an ignition strategy is still used, the ignition time set may not be appropriate, thereby failing to effectively protect the passengers, and even causing additional harm to the passengers, thereby reducing the safety of the vehicle.

[0058] Embodiments of the present disclosure will be described below in greater detail with reference to the accompanying drawings. While certain embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be embodied in various forms and should not be interpreted as being limited to the embodiments set forth herein, but rather, these embodiments are provided so as to more completely and thoroughly understand the present disclosure. It is understood that the drawings and embodiments of the present disclosure are for exemplary purposes only and are not intended to limit the scope of protection of the present disclosure.

[0059] Before introducing the vehicle safety control method, apparatus, storage medium and electronic device provided by the present disclosure, first, the application scenario involved in each embodiment of the present disclosure is introduced, which can be a vehicle driving scenario. In this scenario, when the vehicle collides with the surrounding collision object, taking the moment when the vehicle contacts the collision object as 0 time, the time axis of the vehicle colliding with the surrounding collision object can be as shown in Figure 1 ​​​​T0 is the time when the vehicle contacts the collision object. T1 is the time when the vehicle perceives that a collision is likely to occur, also known as the time when the ignition algorithm is entered. Because the driving acceleration of the vehicle is still small when the vehicle just contacts the collision object, a severe collision can only be identified when the time continues for a period of time until the driving acceleration of the vehicle continues to increase to a certain extent. T2 is the activation time of the safety restraint device, for example, the time when the airbag is detonated. T3 is the activation duration of the safety restraint device, for example, the time when the airbag is filled. T4 is the time when the vehicle collision accident ends, which is generally a few seconds or a few minutes after the collision. T7 is the time when the peripheral sensor such as the radar and the image acquisition device detects that there is an obstacle around the vehicle, which is generally a few minutes or a few tens of seconds before the collision. T6 is the time when the peripheral sensor detects that there is a collision object around the vehicle and through comprehensive calculation, it is known that the collision in the future is inevitable, which is generally a few seconds before the collision. T5 is the time when the collision in the future is inevitable and the collision will cause harm to the passengers, and the safety restraint device and other component systems need to be triggered before the collision occurs, which is generally 1s before the collision.

[0060] The vehicle can be manually driven by a driver or automatically driven under the control of an automatic driving function. The vehicle can be a car, which is not limited to a traditional car, a pure electric car or a hybrid car, and can also be applicable to other types of motor vehicles or non-motor vehicles.

[0061] Figure 2 A flowchart of a vehicle safety control method according to an exemplary embodiment is shown. As shown in Figure 2 The method can include the following steps:

[0062] Step 101, obtaining the state information of the collision object around the vehicle, the driving state information of the vehicle, and the passenger posture information of the passengers on the vehicle.

[0063] For example, first, a radar and an image acquisition device (for example, a camera and an image sensor) can be arranged outside the vehicle. During the driving of the vehicle, the state information of the collision object around the vehicle can be acquired by the radar and the image acquisition device arranged outside the vehicle, and the driving state information of the vehicle itself can also be acquired. The collision object around the vehicle can be other vehicles, pedestrians, and obstacles that can collide with the vehicle, and the state information can include, for example, the position, moving direction, moving speed of the collision object, and the distance between the collision object and the vehicle. The driving state information can include, for example, the driving direction, driving speed, and driving acceleration of the vehicle. In addition, the passenger posture information of the passengers on the vehicle can also be acquired, the passengers can include the driver and the passengers on the vehicle, and the passenger posture information can include, for example, the distance between the passengers and the objects in the vehicle, the position of the passengers, and the body orientation of the passengers.

[0064] In step 102, the collision condition and the collision time of the vehicle and the collision object are determined according to the driving state information and the state information.

[0065] In this step, the collision risk of the vehicle and the collision object can be analyzed according to the driving state information and the state information, and then the collision condition and the collision time can be determined according to the analysis result. The collision risk can be divided into five types: (1) no risk, and the safety restraint device does not need to be activated. Possible scenarios: a) no one in the vehicle, whether the vehicle is in a stationary state or a moving state, b) the vehicle is in a stationary state, and there is no moving collision object in the surrounding preset range (the preset range can be set according to the vehicle condition), c) the vehicle is in a moving state, and there is no collision object in the specified range in front of the moving direction of the vehicle (the specified range can be determined according to the driving speed and the braking ability of the vehicle, for example, the driving speed is 100 km / h, and the braking distance is 40 meters, so the specified range can be set to 50 meters in front of the vehicle). (2) The second type has the possibility of collision, but the risk of collision is very small. Possible scenarios: a) the vehicle is in a stationary state, and there is a moving collision object in the surrounding preset range, but it is judged that the collision object will not collide with the vehicle according to the moving speed of the collision object, b) the vehicle is in a moving state, and there is a moving collision object in the specified range in front of the moving direction of the vehicle, the moving direction of the collision object is the same as the driving direction of the vehicle, but it is determined that the collision object will not collide with the vehicle according to the driving speed of the vehicle, the moving speed of the collision object, and the braking ability. (3) The third type has the inevitability of collision, although no actual collision has occurred. (4) The fourth type has a collision, but the harm to the passengers is small, for example, the vehicle collides with the collision object at a low speed or the vehicle door is closed. (5) The fifth type actually collides, and the harm to the passengers is large.

[0066] Specifically, the driving state information and the state information can be preprocessed (for example, filtering processing, alignment processing, etc.), and the collision condition and the collision time of the vehicle colliding with the collision object can be determined according to the preprocessed driving state information and the state information. The collision condition is used to indicate the specific type of the vehicle colliding with the collision object, for example, the collision condition can include a same direction collision condition and a side collision condition. The same direction collision condition is used to represent that the vehicle collides with the collision object moving in the same direction (for example, the vehicle collides with the other vehicle in front of it), and the side collision condition is used to represent that the side of the vehicle body is hit by the collision object.

[0067] In step 103, the target safety restraint device and the target activation time of the target safety restraint device are determined from the plurality of safety restraint devices according to the collision condition, the occupant posture information, the preset activation duration of the safety restraint device, and the collision time.

[0068] Specifically, the safety restraint device is used to protect the occupant on the vehicle when the vehicle collides, and each safety restraint device corresponds to a preset activation duration, which is used to represent the duration from the start of the safety restraint device to the completion of the start. The safety restraint device can be an airbag, an air curtain, an air cushion, etc. Taking the safety restraint device as an airbag as an example, a plurality of airbags can be arranged in the steering wheel, the right side trim panel of the center console, below the center console, outside the seat, and on both sides of the roof, etc. The preset activation duration can be the filling time of the airbag, which is about 20 to 50 ms. After determining the collision condition, the target safety restraint device required to be started when the vehicle collides with the collision object can be determined according to the collision condition and the occupant posture information. Then, the target activation time of the target safety restraint device can be set according to the preset activation duration of the target safety restraint device and the collision time.

[0069] In step 104, the target safety restraint device is activated according to the target activation time.

[0070] For example, after determining the target safety restraint device and the target activation time, the target safety restraint device can be activated according to the target activation time. In addition, when the vehicle is an electric vehicle, the battery pack of the electric vehicle can be powered off at the same time as the target safety restraint device is activated to ensure the safety of the occupant on the vehicle. For example, in the case of the safety restraint device being an airbag, the target safety restraint device can be at least one target airbag in the plurality of airbags, and the target activation time can be the target ignition time of the target airbag. After determining the target airbag and the target ignition time, the target airbag can be ignited according to the target ignition time, so that the target airbag inflates and expands, thereby reducing the damage to the occupant when the vehicle collides with the collision object.

[0071] It should be noted that the activation strategy in the related art is by means of the acceleration signal of the vehicle, and therefore can only cover a time period from the time when the vehicle is perceived to possibly collide with the collision object to the activation time of the safety restraint device (i.e., the time period T1-T2 in Figure 1 However, the activation strategy in the present disclosure introduces the state information of the collision object and the occupant posture information, and can not only cover the original time period, but also cover the entire collision process (i.e., the time period T7-T4 in Figure 1 Therefore, the activation strategy of the present disclosure increases the time axis before the vehicle collides, makes the target activation time of the target safety restraint device more flexible, and can adapt to the scenario where the driving posture and the sitting posture of the occupant are in different states.

[0072] In summary, the present disclosure first acquires the state information of the collision object around the vehicle, the driving state information of the vehicle, and the occupant posture information of the occupant on the vehicle, then determines the collision condition of the vehicle and the collision object and the collision time of the vehicle and the collision object according to the driving state information and the state information, and determines the target safety restraint device and the target activation time of the target safety restraint device from a plurality of safety restraint devices according to the collision condition, the occupant posture information, the preset activation duration of the safety restraint device, and the collision time, and then activates the target safety restraint device according to the target activation time. The present disclosure can set a suitable target activation time by combining the collision condition, the collision time, and the preset activation duration with the occupant posture information, and activate the target safety restraint device according to the suitable target activation time, which can better adapt to the scenario where the driving posture and the sitting posture of the occupant are in different states, thereby effectively protecting the occupant, avoiding additional harm to the occupant, and improving the safety of the vehicle.

[0073] Figure 3 is a flowchart of step 102 according to the embodiment shown in Figure 2 As shown in Figure 3 , step 102 can include the following steps:

[0074] Step 1021, determining the relative motion direction of the collision object and the vehicle according to the driving state information and the state information, the relative motion direction including same direction motion and non-same direction motion.

[0075] Step 1022, determining the collision condition and the collision time according to the relative motion direction, the driving state information, and the state information. The collision condition includes: same direction collision condition and side collision condition.

[0076] For example, the state information includes the initial position, direction of movement, speed of movement of the colliding object, and a first distance between the colliding object and the vehicle. The driving state information includes the vehicle's driving direction, speed, and acceleration. After obtaining the state information and driving state information, the relative motion direction between the colliding object and the vehicle can be determined using geometric principles based on the initial position, direction of movement of the colliding object, and driving direction of the vehicle. Then, if the relative motion direction is the same, the vehicle and the colliding object are determined to have collided and the collision time based on the speed of movement, the first distance, speed, and acceleration. If a collision is determined, the collision condition is determined to be a same-direction collision condition. If the relative motion direction is different, the vehicle and the colliding object are determined to have collided and the collision time based on the initial position, direction of movement, speed of movement, first distance, driving direction, speed, and acceleration. If a collision is determined, the collision condition is determined to be a side collision condition. The determination of whether a collision occurs and the collision time can be found in descriptions in related technologies, and this disclosure will not elaborate on them.

[0077] Figure 4 It is based on Figure 2 The illustrated embodiment shows a flowchart of step 103. For example... Figure 4 As shown, the occupant posture information includes a second distance between the occupant and the target object inside the vehicle, the occupant's position, and the occupant's body orientation. Step 103 may include the following steps:

[0078] Step 1031: Determine the target safety restraint device based on the collision conditions, the occupant's position, and the occupant's body orientation.

[0079] For example, the occupant posture information can include a second distance between the occupant and a target object in the vehicle, a position of the occupant, and a body orientation of the occupant. The target object can be a steering wheel, a vehicle door, a vehicle seat, etc., and the body orientation of the occupant can be determined by the steering angle of the vehicle seat, for example, when the steering angle of the vehicle seat corresponding to the driver's seat is 180°, it can be considered that the body orientation of the driver is opposite to the forward direction of the vehicle, and the body orientation of the occupant can also be determined by shooting an image of the occupant and identifying the body orientation of the occupant through image recognition. After determining the collision condition, the target safety restraint device to be activated when the vehicle collides with the collision object can be determined according to the collision condition, the position of the occupant, and the body orientation of the occupant. For example, when the safety restraint device is an airbag, if there is only one occupant in the vehicle, the occupant is located on the driver's seat, and the body orientation of the occupant is towards the forward direction of the vehicle, and the collision condition is a same-direction collision condition (for example, the vehicle collides with the collision object from behind), at this time, the body of the occupant will incline forward due to inertia when the collision occurs, and therefore the target airbag to be activated can be the airbag located in the steering wheel, below the center control, outside the seat, and at the positions of the two side roofs.

[0080] In step 1032, the target activation time is determined according to the collision condition, the second distance, the preset activation duration, and the collision time.

[0081] Specifically, when the collision condition is a same-direction collision condition, the target activation time can be determined according to the second distance, the preset activation duration, and the collision time. Taking the safety restraint device as an airbag as an example, when the driving posture of the occupant is in a normal posture, the distance from the head to the steering wheel is 450 mm, and the airbag deployment space is 300 mm. If the vehicle is in a same-direction collision condition, at this time, the body of the occupant will incline forward due to inertia when the collision occurs, and the distance from the head to the steering wheel will decrease (assuming that the distance from the head to the steering wheel decreases from 450 mm to 350 mm), which will cause the airbag to contact the head, chest, and other parts during the inflation process, thereby increasing the harm to the occupant. Therefore, according to the second distance, the preset activation duration, and the collision time, a target activation time can be set, which can make the target safety restraint device fully inflated before the occupant contacts the target safety restraint device, so as to reduce the harm to the human body caused by the vehicle collision.

[0082] In the case of the collision condition being a side collision condition, the target activation time can be determined according to the moving speed, the preset activation duration and the collision time. Still taking the safety restraint device as the airbag as an example, in the case of the driving posture of the occupant being in a normal posture, the distance between the struck door and the occupant is 150 mm, so that the target airbag can be rapidly deployed when the collision occurs, and a buffer area is formed between the occupant and the struck door, reducing the injury of the occupant. However, when the moving speed of the collision object is high, the extrusion speed of the struck door inward is also high, so that the inward intrusion displacement of the door is greatly increased, which can extrude the deployment space of the target airbag, is not conducive to forming the buffer area, and affects the protection effect on the occupant. Therefore, according to the moving speed, the preset activation duration and the collision time, a target activation time can be set, which can make the target airbag fully filled before the struck door extrudes the deployment space.

[0083] In summary, the present disclosure first acquires the state information of the collision object around the vehicle, the driving state information of the vehicle, and the occupant posture information of the occupant on the vehicle, then determines the collision condition of the vehicle and the collision object according to the driving state information and the state information, and the collision time of the vehicle and the collision object, and determines the target safety restraint device and the target activation time of the target safety restraint device from a plurality of safety restraint devices according to the collision condition, the occupant posture information, the preset activation duration of the safety restraint device and the collision time, and then activates the target safety restraint device according to the target activation time. The present disclosure can set a suitable target activation time by combining the collision condition, the collision time and the preset activation duration with the occupant posture information, and activate the target safety restraint device according to the suitable target activation time, which can better adapt to the scene in which the driving posture and the sitting posture of the occupant are in different states, thereby effectively protecting the occupant, avoiding additional injury to the occupant, and improving the safety of the vehicle.
