Detailed Description

In order that the above objects, features and advantages of the present disclosure may be more clearly understood, a further description of aspects of the present disclosure will be provided below. It should be noted that, without conflict, the embodiments of the present disclosure and features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the disclosure. The embodiments described below by referring to the drawings are exemplary and intended for the purpose of explaining the present disclosure and are not to be construed as limiting the present disclosure.

The following describes a method and a device for detecting a safety belt according to an embodiment of the present disclosure with reference to the accompanying drawings.

The seat belt detection method of the embodiment of the present disclosure may be performed by the seat belt detection apparatus provided by the embodiment of the present disclosure, and the apparatus may be configured in an electronic device.

Fig. 1 is a schematic diagram of a connection structure between a trailer and a towing vehicle according to an embodiment of the present disclosure.

As shown in fig. 1, the trailer caravan provided by the present disclosure may include: the first hanging part, the second hanging part and at least one seat;

the first hanging part and the second hanging part are conductive and are respectively and fixedly connected with a third hanging part and a fourth hanging part of the traction vehicle, and the third hanging part and the fourth hanging part are conductive and are electrically connected; the seat is provided with a safety belt, the safety belt comprises a first conductive fixing part and a second conductive fixing part, after the first fixing parts and the second fixing parts of all safety belts are fixed, the first fixing parts and the second fixing parts of all safety belts are connected in series, and in the serial direction, the first fixing part or the second fixing part positioned at the first position is electrically connected with the first hanging part, and the first fixing part or the second fixing part positioned at the last position is electrically connected with the second hanging part.

The type or style of the first hooking portion and the second hooking portion may be any, for example, may be a lock catch, or may also be a chain, etc., and a power line may also be disposed in the lock catch or the chain, etc., which is not limited in this disclosure.

In addition, the third hooking portion and the fourth hooking portion may be any conductive member, such as one end of a latch, in which a power line may be disposed, and the like, which is not limited in this disclosure.

In addition, the first fixing part and the second fixing part of any seat in the trailer can be understood that the safety belts on the seats are successfully inserted, or the user on the seat wears the safety belts. Therefore, if the first fixing part and the second fixing part of each safety belt in the trailer are fixed, all the safety belts in the trailer can be considered to be successfully inserted. At this time, in the same direction, for example, in the serial direction, the first fixing portion located at the first position is electrically connected to the first hooking portion, and the first fixing portion located at the last position is electrically connected to the second hooking portion, so that all the safety belts can be considered to form a passage, that is, a closed loop.

It can be understood that if the first fixing portion located at the first position is electrically connected to the first hooking portion, the second fixing portion located at the last position is electrically connected to the second hooking portion; or if the first second fixing portion is electrically connected to the first connecting portion, the first fixing portion is connected to the second hanging portion, and the disclosure is not limited thereto.

For example, if there are only 1 seat in the trailer, a seat belt is disposed in the seat, and the seat belt includes a first fixing portion and a second fixing portion that are electrically conductive. Under the condition that the first hanging part is a female port of the lock catch 1, the second hanging part is a female port of the lock catch 2, the third hanging part is a male port of the lock catch 1, and the fourth hanging part is a male port of the lock catch 2, the first hanging part can be connected with a first fixing part of a safety belt of the seat 1, such as a socket end of the safety belt of the seat 1, and the female port of the lock catch 2 can be connected with a second fixing part of the safety belt of the seat 1, such as a clamping groove end of the safety belt. After the seat belt insertion end of the seat 1 is inserted into the seat belt clamping groove end, a closed path, that is, an electric circuit, can be formed between the trailer and the towing vehicle.

If there are 2 seats in the trailer, the 2 seats are each provided with a safety belt, and each safety belt comprises a first conductive fixing part and a second conductive fixing part. Under the condition that the first hanging part is a female port of the lock catch 1, the second hanging part is a female port of the lock catch 2, the third hanging part is a male port of the lock catch 1, and the fourth hanging part is a male port of the lock catch 2, the first hanging part can be connected with a first fixing part of a safety belt of the seat 1, such as a safety belt clamping groove, of the seat 1, for example, can be connected with a safety belt socket end of the seat 2, and the safety belt clamping groove end of the seat 2 can be connected with the female port of the lock catch 2. Thus, in the case where the seat belt insertion end of the seat 1 is inserted into the seat belt clamping groove end and the seat belt insertion end of the seat 2 is inserted into the seat belt clamping groove end, it can be considered that a closed path, that is, an electric circuit, is formed between the towing vehicle and the towing vehicle, and the connection relationship can be as shown in fig. 1A.

Optionally, the male port of the lock catch 1 and the male port of the lock catch 2 can be connected through a wire, or a resistor can be arranged; the male port of the lock catch 1 and the female port of the lock catch 1 can be connected through a buckle, and the female port of the lock catch 1 and the first fixing part or the second fixing part of the seat 1 safety belt can be connected through a wire, and the like.

The above examples are only illustrative, and should not be taken as limiting the connection method between the tractor and the trailer in the embodiments of the present disclosure.

Therefore, in the embodiment of the disclosure, if the first fixed end and the second fixed end of the seat belt of the seat are successfully connected, that is, the seat belt is successfully tied, a closed path is formed between the trailer caravan and the traction vehicle, any position in the path is detected, and a corresponding current value can be obtained. If the first and second fixed ends of the seat belt are not connected, i.e., the seat belt is not fastened, then it can be considered that a closed path is not formed between the trailer and the towing vehicle, and no current value exists at any position, i.e., the current value is zero. Therefore, whether the seat belt on the seat in the trailer is tied or not can be determined according to the obtained current value, and further, a basis is provided for knowing the connection condition of the seat belt in the trailer part, and the like, and the method is not limited in the disclosure.

According to the embodiment of the disclosure, the electric connection between the traction vehicle and the seat belt in the trailer can be established, so that whether the seat belt in the trailer is tied or not can be determined according to the electric connection, the detection of the seat belt in the trailer is realized, and the safety and reliability of the detection of the seat belt in the trailer are improved.

Fig. 2 is a flowchart of a method for detecting a seat belt according to an embodiment of the disclosure. As shown in fig. 2, the seat belt detection method may include the steps of:

step 201, detecting whether an electric loop is formed between the trailer and the towing vehicle, wherein the electric loop comprises a first fixing part and a second fixing part of all safety belts, when the trailer is connected to the towing vehicle.

It should be noted that, the detection method of the safety belt provided by the present disclosure may be applied to the trailer provided by the present disclosure, which is not limited in this disclosure.

The first hitching part and the second hitching part can be arranged in the trailer, and the third hitching part and the fourth hitching part can be arranged in the tractor, wherein the hitching parts are conductive, and the trailer and the tractor can be connected by connecting the first hitching part with the third hitching part and connecting the second hitching part with the fourth hitching part, namely the trailer can be hitched on the tractor. The above-mentioned hanging parts may be any devices or components, for example, may be double-lock catches, lock chains, etc., and the double-lock catches or the lock chains may also be provided with wires, power lines, etc., which are not limited in this disclosure.

In general, a towing vehicle may provide a powertrain and control vehicle travel. Under the condition that the trailer is connected with the traction vehicle, if the traction vehicle starts to run, the connection condition of the seat belts in the trailer cannot be known, and if a certain safety belt is not connected in the trailer, passengers who do not wear the safety belt can be injured when the vehicle is started suddenly or braked suddenly, and a large potential safety hazard exists. Therefore, in the embodiment of the disclosure, in the case that the trailer caravan is connected to the traction vehicle, it may be detected whether an electrical loop is formed between the trailer caravan and the traction vehicle.

Alternatively, it may be determined whether an electrical loop is formed between the tractor and the tractor by detecting a current in the tractor and a line in which the tractor is located, and if the current is detected, it may be determined that the tractor and the tractor form an electrical loop, and if the current is not detected, it may be determined that the tractor and the tractor do not form an electrical loop.

It can be appreciated that in the case where the tractor is connected to the tractor, since the tractor and the tractor workshop form an electrical connection through the first hitching section, the second hitching section, the third hitching section and the fourth hitching section, and there is a circuit connection between the respective safety belts in the tractor, the first hitching section and the second hitching section of the tractor are also electrically connected to the fixing section of the seat, and thus the electrical connection can be made between the tractor and between the safety belts of the tractor. If the first fixing part and the second fixing part of the safety belt of each seat in the trailer are connected, the circuit between the trailer and the traction vehicle can be considered to be in a conducting state, and current exists on the circuit; if the first and second fixing portions of the seat belt of any one of the vehicles are not connected, it can be considered that the circuit between the vehicle and the towing vehicle is in a disconnected state, and no current flows through the circuit.

Optionally, the current at any position on the line where the towing vehicle and the towing room workshop are located may be detected when the towing vehicle is hooked to the towing vehicle, for example, the current at the first hooking portion of the towing vehicle may be detected, or the current at the second connecting portion of the towing room Che Di may be detected, or the current at the third connecting portion, the fourth connecting portion, and other positions of the towing vehicle may be detected. Under the condition that the current exists at any position, the traction vehicle and the trailer room workshop can be considered to form an electric loop; in the event that no current is detected at any location, it is considered that the towing vehicle and the tractor shop do not form a circuit loop, etc., which is not limiting to the present disclosure.

Thus, in the embodiment of the disclosure, the current on the line between the towing vehicle and the towing vehicle can be detected to determine whether an electric loop is formed between the towing vehicle and the towing vehicle.

Step 202, determining the state of the safety belt according to the detection result of detecting whether the trailer car and the traction vehicle form an electric loop.

The state of the seat belt may be various, for example, may be a connected state, or may be unconnected, etc., which is not limited in this disclosure.

In addition, the detection result may be various, for example, an electrical loop may be formed between the tractor and the tractor, or an electrical loop may not be formed between the tractor and the tractor, which is not limited in the disclosure.

Alternatively, it may be determined that all the safety belts are in the connected state if it is detected that the tractor and the trailer form an electrical circuit, and that at least one safety belt is in the disconnected state if it is detected that the tractor and the trailer do not form an electrical circuit. It can be understood that if an electric loop is detected to be formed between the trailer and the towing vehicle, that is, the circuits of the trailer and the towing vehicle are in a conducting state, it can be determined that all safety belts in the trailer are in a connecting state; if it is detected that the tractor and the traction vehicle do not form an electrical loop, that is, the circuit where the traction vehicle and the front tractor are located is in a disconnected state, it may be determined that at least one safety belt in the tractor is in a disconnected state, so that the whole circuit is not conducted, and the disclosure is not limited to this.

Optionally, when at least one safety belt is in a disconnected state, responding to the situation that the traction vehicle is in a driving gear, and performing alarm prompt, or sending a forbidden command to a control module of the traction vehicle so as to enable the control module to control the accelerator to stop working.

It can be appreciated that if the traction vehicle is directly driven into the driving gear under the condition that it is determined that at least one safety belt in the traction motor home is in the disconnected state, accidents and the like may occur to passengers who do not wear the safety belts, and potential safety hazards exist. Therefore, in the embodiment of the disclosure, under the condition that at least one safety belt in the towing motor home is determined to be in a disconnected state, an alarm prompt can be performed in response to the fact that the towing vehicle is hung into a driving gear, so that the driving safety of the vehicle is improved.

The alarm prompt is various, for example, the prompt information such as "the safety belt is not connected", the alarm sound and the like can be played through a loudspeaker, or the prompt word and the like can be set in the display interface to give an alarm and the like, which is not limited by the disclosure.

Or, in the case that it is determined that at least one safety belt in the trailer is in a disconnected state, in order to reduce the potential safety hazard, a forbidden command may be sent to a control module of the towing vehicle, so that the control module controls the accelerator to stop working, and the disclosure is not limited thereto.

According to the embodiment of the disclosure, whether the trailer caravan and the traction vehicle form an electric loop or not can be detected under the condition that the trailer caravan is connected to the traction vehicle, wherein the electric loop comprises the first fixing part and the second fixing part of all safety belts, and then the state of the safety belts can be determined according to the detection result of whether the trailer caravan and the traction vehicle form the electric loop or not. Therefore, when the trailer is connected with the traction vehicle, whether an electric loop is formed between the trailer and the traction vehicle can be detected, and the state of the safety belt is determined according to the detection result, so that the safety belt in the trailer is detected, and the reliability and the accuracy of the safety belt detection in the trailer are improved.

Fig. 3 is a flowchart of a method for detecting a seat belt according to an embodiment of the disclosure. As shown in fig. 3, the seat belt detection method may include the steps of:

step 301, detecting whether the trailer caravan and the towing vehicle form an electric loop or not under the condition that the trailer caravan is connected to the towing vehicle, wherein the electric loop comprises a first fixing portion and a second fixing portion of all safety belts.

In step 302, in case it is detected that the tractor car and the towing vehicle do not form an electrical circuit, it is determined that at least one safety belt is in an open state.

In step 303, in the case that it is detected that the trailer car and the towing vehicle form an electrical circuit, it is determined that all the safety belts are in a connected state.

It should be noted that, the specific content and implementation manner of the steps 301 to 303 may refer to the descriptions of other embodiments of the disclosure, and are not repeated herein.

And 304, acquiring image data acquired by a camera outside the trailer by a circuit forming an electric loop with the trailer in the trailer based on power carrier communication.

The camera may be disposed outside the trailer caravan to collect data around the trailer caravan, for example, may be disposed at a left side position of the trailer caravan, or may also be disposed at a right side position of the trailer caravan, or may also be disposed at a rear side of the trailer caravan, or the like, which is not limited in this disclosure.

It can be appreciated that, because the traction vehicle is located in front, the trailer is located behind the traction vehicle, so that the running condition of other vehicles behind the trailer may not be known in the running process of the traction vehicle, and thus, the image data collected by the external camera of the trailer can be obtained through the circuit of the traction vehicle and the trailer, based on the PLC. The present disclosure is not limited in this regard.

In step 305, environmental data external to the trailer is determined based on the image data.

The environmental data may be other vehicle data around the trailer, or may also be actual environmental data around the trailer, such as width and curvature of a road surface, which is not limited in this disclosure.

It can be understood that after the vehicle traction receives the image data collected by the external camera of the trailer, the environment data outside the trailer can be determined by performing image recognition, image analysis and other processes on the image data.

Step 306, controlling the running state of the traction vehicle based on the environmental data.

For example, if it is determined by processing the image data that other vehicles around the trailer are in a overtaking state, the vehicle may be controlled to maintain the current speed, not to increase the speed, and so on if the vehicle is about to overtake at an increased speed, which is not limited in this disclosure.

Therefore, in the embodiment of the disclosure, the environmental data around the trailer can be determined by analyzing the image data acquired by the external camera of the trailer, and then the running state of the vehicle can be controlled according to the environmental data, so that the running risk of the vehicle is reduced as much as possible, and the running safety and reliability of the vehicle are improved. Optionally, when a preset component in the traction vehicle is triggered, a circuit of an electrical loop is formed between the traction vehicle and the trailer caravan, and a control signal is sent to the trailer caravan based on power carrier communication, wherein the preset component and the component with an adaptation function in the trailer caravan.

The preset component may be a specific component, for example, may be a brake pedal, or may also be a turn signal lamp, etc., which is not limited in this disclosure.

In addition, power line carrier communication (power line communication, PLC) is a communication system specific to a power system, and can use an existing ac or dc power line to transmit analog or digital signals at high speed by the carrier system. Therefore, in the present disclosure, data transmission between the traction vehicle and the traction room workshop can be achieved through electrical connection between the traction vehicle and the traction vehicle.

Optionally, the executing body of the embodiment of the present disclosure may also be a vehicle machine, which may establish a connection with the electrical circuit in the towing vehicle, so that the vehicle machine may obtain, based on the PLC, data transmitted by the towing vehicle, or send the data to the towing vehicle portion, and the disclosure is not limited to this.

It will be appreciated that if the predetermined components in the towing vehicle are triggered, there may be a safety hazard as the trailer may not change in real time based on the triggered predetermined components in the towing vehicle. For example, when a brake pedal in a traction vehicle is triggered, the traction vehicle and a trailer may gradually slow down until the traction vehicle stops running, and other vehicles behind the traction vehicle and the trailer cannot know that the traction vehicle and the trailer are slowing down or stopping, so that the traction vehicle and the trailer may normally run, the running speed may not be changed in time, a rear-end collision may occur, and a certain potential safety hazard exists.

Or if the turn signal lamp in the traction vehicle is triggered, it can indicate that the traction vehicle needs to change direction currently, and other vehicles behind the traction vehicle and the trailer may not know that the traction vehicle and the trailer need to turn in time, so that the traction vehicle and the trailer may normally run, and a certain potential safety hazard exists. Therefore, in the embodiment of the disclosure, when the preset component in the traction vehicle is triggered, the traction vehicle and the trailer may form a circuit of an electrical loop, and control information is sent to the trailer based on the power carrier communication PLC, so that the trailer may perform corresponding control according to the control signal, so as to reduce the potential safety hazard as much as possible.

Alternatively, a brake signal can be sent to the tractor based on the PLC to control the brake lights in the tractor to be turned on through a circuit of the tractor and the tractor to form an electrical loop.

For example, if the brake pedal of the traction vehicle is depressed, it may indicate that the traction vehicle is in a deceleration or braking state currently, so that a circuit can be formed between the traction vehicle and the tractor, and based on the PLC, a brake signal is sent to the tractor portion to control the brake lamp in the tractor to be turned on, so as to transmit the information that the traction vehicle and the tractor are in a braking state currently to other vehicles around, thereby reminding other vehicles to pay attention to the vehicle speed and reducing the potential safety hazard as much as possible.

Or under the condition that the steering lamp of the traction vehicle is triggered, a circuit of an electric loop is formed between the traction vehicle and the trailer, and a steering signal is sent to the trailer based on the PLC so as to control the steering lamp in the trailer to be lighted.

The turn signal lamp may be a right turn signal lamp, or may be a left turn signal lamp, or the like, which is not limited in this disclosure.

For example, if the left turn light of the traction vehicle is triggered, it may indicate that the traction vehicle may be in a left turn or u-turn state, so that a steering signal may be sent to the tractor based on the PLC to control the left turn light in the tractor to light up to indicate other surrounding vehicles through a circuit formed by the traction vehicle and the tractor: the traction vehicle and the trailer are in a left turning state at present, so that other vehicles are reminded of paying attention to the speed, and potential safety hazards are reduced as much as possible.

The above examples are merely illustrative, and are not intended to limit the manner in which the trailer caravan is controlled in the embodiments of the present disclosure.

According to the embodiment of the disclosure, whether the trailer and the traction vehicle form an electric loop or not can be detected under the condition that the trailer and the traction vehicle are connected, wherein the electric loop comprises the first fixing part and the second fixing part of all safety belts, then the safety belts are determined to be in a connection state under the condition that the trailer and the traction vehicle form the electric loop, at least one safety belt is determined to be in a disconnection state under the condition that the trailer and the traction vehicle are not connected, then an electric loop can be formed through a circuit of the traction vehicle and the trailer, image data collected by a camera outside the trailer can be obtained based on power carrier communication, environmental data outside the trailer can be determined based on the image data, and then the running state of the traction vehicle can be controlled based on the environmental data. Therefore, under the condition that the trailer is connected to the traction vehicle in a hanging mode and the electric loop is formed between the trailer and the traction vehicle, the data transmission between the traction vehicle and the trailer workshop can be realized based on power carrier communication through a circuit of the electric loop formed between the traction vehicle and the trailer, so that the control of the traction vehicle and/or the trailer is realized, potential safety hazards are reduced as much as possible, and the safety and reliability of vehicle running are improved.

The embodiment of the disclosure also provides a detection device of the safety belt.

and controlling the running state of the traction vehicle based on the environmental data.

Optionally, the device further includes a sending module, configured to:

and under the condition that a preset part in the traction vehicle is triggered, a control signal is sent to the traction vehicle on the basis of power carrier communication through a circuit of the electric loop formed by the traction vehicle and the traction vehicle, wherein the preset part is a part with an adaptation function in the traction vehicle.
