The front cover of the vehicle refers to a covering part at the top of a front cabin (or engine compartment, engine compartment) of the vehicle, and is also called an engine compartment cover or an engine cover.
Specifically, the running speed information of the vehicle may include, for example, one or a combination of plural kinds of information such as a running speed, a running acceleration, and the like of the vehicle. The preset safe range in front of the vehicle may be a detectable range of the obstacle detecting device 30, or may be a distance range custom-set by the user according to actual needs, for example, the preset safe range in front of the vehicle may be set to a range of 1m from the front end of the vehicle. The pedestrian information within the preset safety range in front of the vehicle can be used for indicating whether a pedestrian exists within the preset safety range in front of the vehicle and the distance between the pedestrian and the front end of the vehicle.
It can be understood, the protecgulum control system that this embodiment provided, including controller and the travel information collection system and the obstacle detection device who are connected with the controller respectively, the speed information of traveling through the vehicle can be gathered to the information collection system that travels of vehicle, can survey the pedestrian information in the preset safety range in vehicle the place ahead through the obstacle detection device, by the controller based on the speed information of traveling of vehicle and the pedestrian information automatic control protecgulum actuating mechanism in the preset safety range in the place ahead raise the protecgulum of vehicle, and then increase the clearance between the engine compartment part of pedestrian and vehicle, avoid the part in the engine compartment of pedestrian's head collision, play the effect of protection pedestrian. Compared with the prior art that the front cover driving mechanism is triggered to work when the collision sensor installed on the front bumper of the vehicle detects that the vehicle collides, the problem that the front cover driving mechanism is mistakenly triggered to lift the front cover and avoids the collision between pedestrians and the vehicle to cause the non-triggered front cover driving mechanism to work under the condition that the front cover is not required to be lifted can be avoided, and therefore the front cover driving mechanism can work more accurately and reliably, meanwhile, the maintenance cost of the vehicle after collision is reduced, and resources are saved while the pedestrians are protected.
In order to make those skilled in the art better understand the technical solutions provided by the embodiments of the present application, the following describes each component unit in the front cover control system provided by the embodiments of the present application in detail with reference to specific examples.
In the embodiment of the application, the collision triggering condition can be set by user according to needs. Alternatively, in order to avoid the problem that the vehicle triggers the front cover driving mechanism to operate after colliding with a pedestrian and the problem that the front cover driving mechanism is triggered to operate by mistake when the vehicle collides with a non-pedestrian, the collision triggering condition may be set as: a pedestrian exists in a preset safety range in front of the vehicle and a collision occurs between the vehicle and the pedestrian. Accordingly, the controller 40 may predict whether the vehicle and the pedestrian may collide based on the distance between the pedestrian and the vehicle collected by the obstacle detecting device 30 and the traveling speed of the vehicle collected by the traveling information collecting device 20 in a case where it is detected that the pedestrian exists within the preset safety range in front of the vehicle by the obstacle detecting device 30, and if the prediction result is yes, determine that the traveling state of the vehicle satisfies the collision triggering condition, and then control the front cover driving mechanism 10 to lift the front cover of the vehicle, increase the gap between the pedestrian and the parts in the engine compartment of the vehicle, prevent the head of the pedestrian from colliding with the parts in the engine compartment, and play a role of protecting the pedestrian.
Further, in consideration of the fact that secondary damage or more serious damage may be caused to the pedestrian during the raising of the front cover of the vehicle by the front cover driving mechanism 10 in the case where the traveling speed of the vehicle is excessively fast, for this reason, the collision triggering condition may be set such that the pedestrian exists within a preset safety range in front of the vehicle, the collision between the vehicle and the pedestrian occurs, and the traveling speed of the vehicle is within a preset speed range. The preset speed range can be set by self-definition according to experience, for example, the preset speed range can be set to be 20 km/h-55 km/h.
Accordingly, the controller 40 may predict whether the vehicle and the pedestrian may collide based on the distance between the pedestrian and the vehicle collected by the obstacle detecting device 30 and the traveling speed of the vehicle collected by the traveling information collecting device 20 in a case where it is detected that the pedestrian exists within the preset safety range in front of the vehicle by the obstacle detecting device 30, determine that the traveling state of the vehicle satisfies the collision triggering condition if the prediction result is that the traveling speed of the vehicle is within the preset speed range, and further control the front cover driving mechanism 10 to raise the front cover of the vehicle, increase a gap between the pedestrian and parts in the engine compartment of the vehicle, prevent the head of the pedestrian from colliding with the parts in the engine compartment, and play a role of protecting the pedestrian.
It should be noted that the controller 40 may estimate the time when the collision between the vehicle and the pedestrian will occur according to the distance between the vehicle and the pedestrian and the driving speed of the vehicle, and may determine that the collision between the vehicle and the pedestrian will occur if the time is less than the preset time threshold. Of course, the controller 40 may determine whether a collision between the vehicle and the pedestrian occurs in any other conventional manner, which is not limited in the embodiments of the present application.

Optionally, the obstacle detecting device 30 may include a camera 31 and a detector 32, where the camera 31 may collect an image of an environment in front of the vehicle, and the detector 32 may detect whether an obstacle exists within a preset safety range in front of the vehicle and acquire a distance between the obstacle and the vehicle.
In particular, the camera 31 may be any type of camera that can be mounted on the vehicle and faces the front of the vehicle, such as on the side of the vehicle interior mirror facing the front of the vehicle. Of course, the camera 31 may also be directly a vehicle drive recorder. The detector 32 may be any type of detector, such as a radar for the detector 32, or a proximity sensor for the detector 32, etc. The detector 32 may be mounted at the front end of the vehicle, for example on the front bumper of the vehicle.
The environmental image that is gathered by camera 31 and the obstacle information that is detected by detector 32 are transmitted controller 40, judge whether there is the pedestrian in the preset safety range in vehicle the place ahead by controller 40 based on environmental image and obstacle information, and then be in under the condition that exists the pedestrian in the preset safety range, judge whether the running state of vehicle satisfies collision trigger condition based on the distance between pedestrian and the vehicle and the speed information of traveling of vehicle to when the running state of vehicle satisfies collision trigger condition, control protecgulum actuating mechanism 10 is raised the protecgulum of vehicle, increase the clearance between the engine compartment interior part of pedestrian and vehicle, avoid the part of pedestrian's head collision in the engine compartment, play the effect of protecting the pedestrian.
Specifically, the controller 40 may identify an obstacle based on the environmental image collected by the camera 31 in a case where the presence of the obstacle within a preset safety range in front of the vehicle is detected by the detector 32, so as to determine whether the obstacle is a pedestrian.
It can be understood that the pedestrian information within the preset safety range in front of the vehicle is detected by adopting the camera and the detector, so that the realization is simple and the cost is low.
The controller 40 in the embodiment of the present application may be any control unit having a data processing function. Preferably, the controller 40 may be a BCM (Body Control Module) of the vehicle, so that a separate ECU (Electronic Control Unit) does not need to be introduced into the vehicle, and the front cover driving mechanism 10 is directly controlled by the BCM of the vehicle, thereby simplifying the overall Control architecture of the vehicle and reducing the cost.
An embodiment of the present application further provides a vehicle, including the front cover control system according to any one of the above embodiments of the present application.
Referring to fig. 3, an embodiment of the present application provides a front cover control method, which may be applied to a control element of a vehicle, such as an ECU or a BCM of the vehicle. As shown in fig. 3, the front cover controlling method includes the steps of:

S304, detecting pedestrian information in a preset safety range in front of the vehicle.
The preset safety range in front of the vehicle may be a detectable range of an obstacle detection device mounted on the vehicle, or may be a distance range which is set by a user in a customized manner according to actual needs, for example, the preset safety range in front of the vehicle may be set to a range of 1m from the front end of the vehicle.
The pedestrian information within the preset safety range in front of the vehicle can be used for indicating whether a pedestrian exists within the preset safety range in front of the vehicle and the distance between the pedestrian and the front end of the vehicle.
In an implementation, the pedestrian information within the preset safety range in front of the vehicle may be detected by an obstacle detecting device installed on the vehicle, for example, the obstacle detecting device may be the obstacle detecting device 30 in the front cover control system according to any of the above embodiments of the present application.
And S306, judging whether the driving state of the vehicle meets the collision triggering condition or not based on the driving speed information and the pedestrian information in the preset safety range.
In an alternative embodiment, in order to avoid the problem that the vehicle triggers the front cover driving mechanism to operate after colliding with the pedestrian and the problem that the front cover driving mechanism is triggered to operate by mistake when the vehicle collides with the non-pedestrian, the collision triggering condition may be set as follows: a pedestrian exists in a preset safety range in front of the vehicle and a collision occurs between the vehicle and the pedestrian. Accordingly, this step may include: and under the condition that the existence of the pedestrian is detected within the preset safety range in front of the vehicle, predicting whether the vehicle and the pedestrian collide or not based on the collected distance between the pedestrian and the vehicle and the driving speed of the vehicle, and if the prediction result is yes, determining that the driving state of the vehicle meets the collision triggering condition.
In another alternative embodiment, considering that a pedestrian may be damaged secondarily or more seriously during the process of lifting the front cover of the vehicle by the front cover driving mechanism in the case that the driving speed of the vehicle is too fast, the collision triggering condition may be set as that a pedestrian exists within a preset safety range in front of the vehicle, a collision between the vehicle and the pedestrian occurs, and the driving speed of the vehicle is within a preset speed range. The preset speed range can be set by self-definition according to experience, for example, the preset speed range can be set to be 20 km/h-55 km/h.
Accordingly, this step may include: under the condition that a pedestrian is detected to exist in a preset safety range in front of a vehicle, whether the vehicle and the pedestrian collide is predicted based on the collected distance between the pedestrian and the vehicle and the driving speed information of the vehicle; and if the vehicle and the pedestrian collide and the running speed of the vehicle is within a preset speed range, determining that the running state of the vehicle meets the collision triggering condition.
It should be noted that, for the two embodiments, the pedestrian information in the preset safety range in front of the vehicle can be detected as follows: whether there is the barrier in the safety range of predetermineeing through the detector detection vehicle the place ahead under the condition that there is the barrier in the safety range of predetermineeing, acquire the barrier through the detector with distance between the vehicle to through the environment image of camera acquisition vehicle the place ahead, further discern the barrier based on the environment image, with confirm whether the barrier is the pedestrian. Therefore, the pedestrian information in the preset safety range in front of the vehicle can be acquired.
And S308, if the running state of the vehicle meets the collision triggering condition, controlling a front cover driving mechanism of the vehicle to lift the front cover of the vehicle.
Specifically, the front cover driving mechanism of the vehicle may include an actuator for raising or lowering the front cover of the vehicle and a squib operating with the actuator, and when it is determined that the driving state of the vehicle satisfies the collision trigger condition, a squib instruction may be output to the squib so that the squib drives the actuator to raise the front cover of the vehicle according to the squib instruction.
It can be understood that, according to the front cover control method provided by the embodiment, the front cover driving mechanism is automatically controlled to lift the front cover of the vehicle based on the traveling speed information of the vehicle and the pedestrian information in the front preset safety range, so that the gap between the pedestrian and the parts in the engine compartment of the vehicle is increased, the head of the pedestrian is prevented from colliding with the parts in the engine compartment, and the function of protecting the pedestrian is achieved. Compared with the prior art that the front cover driving mechanism is triggered to work when the collision sensor installed on the front bumper of the vehicle detects that the vehicle collides, the problem that the front cover driving mechanism is mistakenly triggered to lift the front cover and avoids the collision between pedestrians and the vehicle to cause the non-triggered front cover driving mechanism to work under the condition that the front cover is not required to be lifted can be avoided, and therefore the front cover driving mechanism can work more accurately and reliably, meanwhile, the maintenance cost of the vehicle after collision is reduced, and resources are saved while the pedestrians are protected.
