Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. However, it will be apparent to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
The technical solution of the present application will be described below by way of specific examples.
Referring to fig. 1, a schematic flowchart of steps of a control method for a cabin cover according to an embodiment of the present application is shown. The method for controlling the engine room cover in the embodiment may be applied to a vehicle with the engine room cover, and the main body for executing the method in the embodiment may be an engine room controller, and the engine room controller may be connected with a vehicle controller of the vehicle. The control method of the nacelle cover in the embodiment may specifically include the steps of:
s101, when the cabin cover is in an open state, detecting a target area through a vehicle-mounted device, wherein the target area is an area of a preset range of the cabin.
The nacelle controller may determine whether the nacelle cover is open according to a previously received control instruction for the nacelle cover. For example, when the cabin controller has not received a closing instruction for the cabin cover after receiving an opening instruction for the cabin cover, it may be determined that the cabin cover is still in the open state.
In one possible implementation, the vehicle may be equipped with a camera device by which it is possible to detect whether the bonnet is open. For example, a camera capable of rotating 360 degrees can be installed behind the vehicle, and the cabin controller can determine whether the cabin cover is in an open state or not through image data collected by the camera.
The target area is an area within a preset range of the nacelle, and the area within the preset range may be an area capable of operating the nacelle, for example, the area within the preset range may be an area having a distance from an edge portion of the nacelle cover smaller than a preset length, and a user may operate the nacelle within the area within the preset range. The area within the preset range can also be an area which is less than the preset length from any point of the vehicle, and the vehicle can be overhauled in the area within the preset range.
The onboard device may include a camera device, a radar, and/or a sensing device. The camera device can comprise a camera capable of rotating 360 degrees and/or an infrared camera. Based on the 360-degree rotating camera, the cabin controller can acquire image data including a target area picture. After the cabin controller receives the image data, the image in the target area can be cut out for each video frame of the image data, and then a plurality of continuous video frames about the target area are obtained. The cabin controller may perform target detection on a plurality of consecutive video frames of the target area by using a preset target detection algorithm, so as to detect whether a target object exists in the target area. Based on the infrared camera, the cabin controller can detect whether a living body exists in the target area and determine the corresponding size of the living body, so that whether a target object exists in the target area is determined. The cabin controller can also detect whether a person is in the target area through the radar. The sensing device can be a pressure sensor, and when the cabin controller detects that the cabin cover is subjected to the pressure within the preset range through the pressure sensor, the cabin controller can determine that a person overhauls the cabin, so that the person in the target area can be determined.
And S102, if the target object is not detected in the target area, controlling a timer to start timing.
The target object may be a person, such as a user or a service person. The presence of a person in the target area may indicate that the user currently knows that the hood is open. For example, if a user is taking an item in the cabin or a maintenance person is repairing the equipment in the cabin, the user knows the open state of the cabin cover.
If no target object is detected in the target area, the flap may forget to close, but it is not fully certain that the user has forgotten to close the flap and may simply leave temporarily. At this time, the cabin controller may perform timing by a timer, and the timing duration is used to indicate a time length that the cabin cover is in the closed state and the target object does not exist in the target area range.
If the target object is detected in the target area when the timing duration does not reach the preset time threshold, determining that the user only temporarily leaves at the moment; at this point the timer may be reset and stopped. When the target object is not detected again in the target area, the timer may be controlled to count again. If the timing duration does not reach the preset time threshold, the cabin cover is closed, and the timer can be controlled to reset and stop timing.
S103, if the timing duration reaches a preset time threshold value and the engine room cover is always in an open state in the timing duration, driving an electric stay bar connected with the engine room cover to contract so as to close the engine room cover.
The nacelle cover may be connected to a motorized strut, which may be extended or retracted. When the electric stay bar extends, the engine compartment cover can be driven to open; when the electric stay bar is contracted, the cabin cover can be driven to close. The movable support rod can be provided with a corresponding motor, and when the motor rotates, the electric support rod can be driven to extend or contract. The motor can comprise two rotating directions, wherein one rotating direction is used for driving the electric stay bar to extend; the other rotation direction is used for driving the electric stay bar to contract.
When the timing duration reaches a preset time threshold and the engine room cover is always in an open state within the timing duration, the user can be considered to forget to close the engine room cover, and the electric stay bar can be driven to contract at the moment, so that the engine room cover is closed.
In a possible implementation manner, when the timing duration reaches a preset time threshold and the engine compartment cover is always in an open state within the timing duration, a prompt message may be sent to a user terminal associated with the vehicle to prompt a user that the user is not closed, so as to obtain a control instruction of the user for the engine compartment cover.
When the engine room cover is closed, the engine room controller can send a control command to the motor of the electric stay bar, and the motor can rotate according to the rotating direction carried in the control command after receiving the control command, so that the electric stay bar is driven to contract.
The nacelle cover may comprise a nacelle cover lock which may lock the nacelle cover when the nacelle cover is closed, so that the nacelle cover may not be pulled apart by an external force. The cabin cover lock can be a self-suction lock, and in the closing process of the cabin cover, when the cabin cover is closed to a preset angle, the cabin controller can detect a half-lock signal so as to drive a motor of the self-suction lock to rotate, so that the self-suction lock is controlled to pull the cabin cover to a locking position and lock the cabin cover
In one possible embodiment, the nacelle cover lock can be locked or unlocked by switching the current. When the cabin cover is closed, the cabin controller can control a switch connected with the cabin cover lock to be closed, so that current is generated in the cabin cover lock, and the cabin cover lock is locked; when the cabin cover is opened, the cabin controller can control a switch connected with the cabin cover lock to be disconnected, so that the current in the cabin cover lock is disconnected, and the cabin cover lock is opened.
In this embodiment, when the cabin cover is in the open state, whether the user forgets to close the cabin cover or mistakenly opens the cabin cover can be determined by detecting whether the target object exists in the target area, so that when the user forgets to close the cabin cover and mistakenly opens the cabin cover, the cabin cover can be closed, and it is ensured that articles or equipment in the cabin are not damaged.
Referring to fig. 2, a schematic flow chart illustrating steps of a control method for a nacelle cover according to an embodiment of the present disclosure is shown. The method for controlling the engine room cover in the embodiment may be applied to a vehicle with the engine room cover, and the main body for executing the method in the embodiment may be an engine room controller, and the engine room controller may be connected with a vehicle controller of the vehicle. The control method of the engine room cover in the embodiment may specifically include the following steps:
s201, responding to an opening instruction for the engine room cover, and sending a data acquisition instruction to the camera device and/or the sensing device to acquire image data and/or sensing data in the target area.
The unlock command may be triggered by a smart key of the vehicle. For example, the user may send a turn-on instruction to the in-vehicle terminal by pressing the smart key. The fob may include a button that may be used to control the opening or closing of the hatch cover. When the cabin cover is in a closed state, if the vehicle-mounted terminal detects a pressing signal of the button, the opening instruction can be determined to be a closing instruction; when the cabin cover is in an open state, if the vehicle-mounted terminal detects a pressing signal of the button, it may be determined that the open command is an open command. The intelligent key can also comprise an opening button and a closing button, and when the vehicle-mounted terminal detects a pressing signal of the opening button, the vehicle-mounted terminal can determine that an opening instruction for the engine room cover is received; when the in-vehicle terminal detects a pressing signal of the close button, it may be determined that a close instruction for the hood is received. The opening instruction may also be triggered by a voice signal. The vehicle-mounted terminal can detect voice information, and when a voice signal corresponding to the opening instruction is detected, the vehicle-mounted terminal can determine that the opening instruction is received. The opening instruction can be triggered through a mobile phone APP. Wherein the cell phone APP may be associated with a vehicle. The user can send the opening instruction to the vehicle-mounted terminal through the APP. For example, when the user opens the APP interface, the user can see a plurality of touch keys, and when the user selects a key for opening the hood, the in-vehicle terminal can receive an opening instruction for the hood. The turn-on command may also be triggered by a central control screen on the vehicle. The central control screen can be installed on a vehicle, the central control screen can comprise a plurality of selection interfaces, and a user can switch to the control interface of the engine room cover when controlling the engine room cover. The control interface of the engine compartment cover can comprise a plurality of touch keys, and when a user selects the keys for opening the engine compartment cover, the vehicle-mounted terminal can receive an opening instruction for the engine compartment cover.
The starting instruction can be sent to the vehicle control unit, and then the vehicle control unit sends the starting instruction to the cabin controller; or may be sent directly to the nacelle controller.
When the cabin controller receives an opening instruction for the cabin cover, a data acquisition instruction can be sent to a camera device and/or a sensing device installed on the vehicle, so that the camera device and/or the sensing device can receive the data acquisition instruction while the cabin cover is opened. When the engine compartment cover is opened, the camera device and/or the sensing device can acquire data.
The camera device can be a camera capable of rotating by 360 degrees, and when receiving a data acquisition instruction, the camera device can drive the camera to rotate, so that a shooting area of the camera is aligned to a target area, and image data including a target area picture is acquired. After the camera collects the image data, the image data can be sent to the cabin controller, and the cabin controller can detect whether a target object exists in a target area according to the image data collected by the camera in real time.
The sensing device can be a pressure sensor, a temperature sensor and the like which are arranged on the cabin cover and the engine, and can detect the stress condition or the temperature of the cabin cover so as to determine whether the transmitter is overhauled.
S202, detecting the target object according to the image data and/or the sensing data.
Performing target detection on the image data through a preset target detection algorithm to obtain a first detection result of a target area; and/or determining a second detection result of the target area according to the sensing data; and determining whether the target object exists in the target area according to the first detection result and/or the second detection result.
The cabin controller may perform target detection on each video frame in the image data using a preset target detection algorithm, so as to determine whether a person is in the target area. In a possible implementation manner, every preset time, the camera can send the acquired real-time video to the cabin controller, the cabin controller can extract the characteristics of each video frame after receiving the real-time video every time, and the characteristics are detected according to the characteristic data in each video frame, so that whether a person exists in the picture corresponding to the target area is determined; the cabin controller can also obtain the current characteristics of the current video frame to be compared with the historical characteristics of the previously received video frame, so that whether a target object enters the target area can be determined.
The cabin controller may compare the acquired sensed data to a preset sensed data threshold to determine whether a person is present in the target area. For example, a pressure threshold may be set, and when the collected pressure of the nacelle cover is greater than the pressure threshold, it is determined that a person is in the target area.
In a possible implementation manner, the detection result of the target area may be obtained jointly according to the first detection result and the second detection result. For example, if both the first detection result and the second detection result are persons in the target area, it may be determined that a person is in the target area.
And S203, if the target object is not detected in the target area, controlling a timer to start timing.
If no person is in the target area, the cabin controller can control the timer to start timing.
In one possible implementation, if the nacelle cover detects that there is a person in the target area, the detection of the target area may be continued until no person in the target area is detected, and then the timing is started.
S204, if the timing duration reaches a preset time threshold and the engine room cover is always in an open state in the timing duration, driving an electric stay bar connected with the engine room cover to contract so as to close the engine room cover.
S203-S204 of this embodiment are similar to S102-S103 of the previous embodiment, and may refer to each other, which is not described herein.
S205, detecting whether the engine room cover is locked.
After the nacelle cover is closed, the nacelle controller may detect whether the nacelle cover is locked.
In one possible implementation, the bonnet lock may be a self-priming lock that may be automatically engaged to lock the bonnet. The self-suction lock controller can be connected with the cabin controller, and can send a control signal to the self-suction lock device when the cabin cover is closed to a preset angle, so that the self-suction lock is controlled to pull the cabin cover to a locking position and lock the cabin cover. When the self-suction lock is locked, the self-suction lock controller can send a locking signal to the cabin controller; if the nacelle controller does not receive the locking signal within the preset time, it may be determined that the nacelle cover is unlocked.
In one possible embodiment, the cabin control unit can detect a sound during the closing of the cabin cover, and can determine that the cabin cover lock is locked when a sound of the cabin cover being locked is detected.
In one possible implementation, the nacelle cover lock may be divided into two parts, one on the nacelle cover and one on the nacelle, and when the nacelle cover is fully closed, the two parts of the nacelle cover lock merge, thereby generating an electric current. If the cabin controller detects that the voltage value in the cabin cover lock is larger than a preset value, the cabin cover lock can be determined to be closed; if the cabin controller does not detect that the cabin cover lock generates a voltage value larger than the preset value within the preset time, the cabin cover lock can be determined to be closed, and the cabin cover is unlocked.
In one possible implementation, the nacelle controller may determine that the nacelle cover is closed when controlling the electric stay to retract to the shortest position. After the nacelle cover is closed, the nacelle controller may drive the motor of the nacelle cover lock to rotate, thereby driving the nacelle cover lock to lock. The nacelle controller may detect the catch position of the nacelle cover lock to determine whether the nacelle cover lock is locked. If the cabin controller detects that the lock position of the cabin cover lock is a preset position, determining that the cabin cover lock is locked; and if the cabin controller detects that the lock position of the cabin cover lock is not at the preset position, determining that the cabin cover lock is unlocked.
If it is detected that the nacelle cover is not locked, step S206 may be performed.
S206, sending prompt information to terminal equipment associated with the vehicle to remind that the cabin cover is unlocked.
Above-mentioned terminal equipment can be user's cell-phone, and cabin controller can send the prompt message to APP on the cell-phone, reminds user cabin cover not locking.
In one possible implementation, the cabin controller may further prompt the user that the cabin cover is unlocked through a smart key, a voice signal, a car light signal, and a central control screen. The intelligent key can comprise an indicator light; if the user sends an opening instruction through the intelligent key, the cabin controller can return prompt information to the intelligent key to light the indicator lamp, so that the user is prompted that the cabin cover is unlocked. The cabin controller may control a microphone device on the vehicle to emit a preset voice signal, thereby alerting a user that the cabin cover is unlocked. The cabin controller may control rear lights of the vehicle to flash at a preset frequency, thereby alerting a user that the cabin cover is unlocked. The cabin controller can send warning information to the central control screen; after the central control screen receives the warning information, a striking warning symbol or warning information can be displayed on a screen interface, so that a user is prompted that the cabin cover is unlocked.
In this embodiment, whether or not a person is present in the target area may be determined based on the in-vehicle device, thereby determining whether or not the hood is closed, and controlling the hood to be closed when the hood is not closed in time. After the cabin cover is closed, whether the cabin cover is locked or not can be detected, and therefore prompt information can be sent to a user when the cabin cover lock cannot be locked.
Referring to fig. 3, a schematic flow chart illustrating steps of a control method for a nacelle cover according to an embodiment of the present disclosure is shown. The method for controlling the engine room cover in the embodiment may be applied to a vehicle with the engine room cover, and the main body for executing the method in the embodiment may be an engine room controller, and the engine room controller may be connected with a vehicle controller of the vehicle. The control method of the nacelle cover in the embodiment may specifically include the steps of:
s301, gear information and vehicle speed information of the vehicle are requested to a vehicle control unit of the vehicle.
The cabin controller and the vehicle controller can carry out data communication through a wireless network or a data bus, so that request information can be sent to the vehicle controller to obtain the current gear information and the current speed information of the vehicle.
S302, determining the state of the vehicle according to the gear information and the vehicle speed information.
If the situation that the vehicle is switched from the first gear to the second gear is monitored, determining that the vehicle is in an open state; and if the vehicle is in the second gear and the vehicle speed is greater than the preset vehicle speed value, determining that the vehicle is in a running state.
The first gear may be a P gear, the second gear may be a D gear, and the preset vehicle speed value may be 5km/h.
In one possible implementation, the cabin controller may receive the gear change signal when the user shifts the gear from the P gear to the D gear. After the cabin controller receives the gear change signal, on one hand, an instrument indicator lamp of the vehicle is driven to give an alarm to prompt a user that a cabin cover is in an open state; on the other hand, the electric stay bar is driven to close the front hatch cover, and the whole vehicle runs forwards after being sucked by the self-sucking lock.
S303, if the vehicle is in a running state or an opening state, whether the cabin cover is closed or not is detected.
When the vehicle is started or the vehicle is running, if the cabin cover is not closed, a potential safety hazard exists, and therefore, whether the cabin cover is closed or not needs to be detected.
In a possible implementation manner, the cabin controller can determine whether the cabin cover is closed or not through the length of the electric stay bar, and the cabin cover controller can acquire the length of the electric stay bar through a preset camera, so as to determine whether the length of the electric stay bar is the shortest length or not. Distance sensing devices can be carried between the two ends of the electric stay bar, and the cabin controller can acquire the values of the distance sensing devices to determine whether the length of the electric stay bar is the shortest length or not, so that whether the cabin cover is closed or not is determined.
In one possible implementation, the nacelle controller may first detect whether the nacelle cover is locked. Based on the step in S205 described above, the nacelle controller may detect whether the nacelle cover is locked. If the nacelle cover is unlocked, the nacelle controller may detect the length of the electric stay to determine whether the nacelle cover is closed. If the nacelle cover is locked, it is determined that the nacelle cover is closed.
S304, if the cabin cover is not closed, controlling a preset alarm device to send out an alarm signal to prompt that the cabin cover is not closed.
The preset alarm device can be installed on a vehicle or can be present on an intelligent key or a user terminal; the warning device may be an instrument panel on the vehicle. The alarm signal can be voice information or light information.
When the cabin controller detects that the cabin cover is not closed, an alarm instruction can be sent to the alarm device to instruct the alarm device to send an alarm signal, so that a user is prompted that the cabin cover is not closed.
S305, driving an electric stay bar connected with the cabin cover to contract so as to close the cabin cover.
