Description

Method and device for intelligently determining passengers to get off safely

Technical field

The present invention relates to the field of security control technologies, and in particular, to a method and apparatus for intelligently determining passengers to get off the vehicle safely.

Background technique

Today's people are unaware of traffic safety. Before taxis or private cars are opened, it is usually not noticed whether there are small vehicles such as bicycles or electric vehicles. However, if the speed of an electric car or a bicycle is too fast at this time, if it is too late to brake, it may cause damage to the person and the car, and even cause serious casualties. Then, how to ensure people's personal safety when getting on and off has become a problem that cannot be ignored.

Summary of the invention

In order to solve the above technical problems, the present invention provides a method and apparatus for intelligently determining that a passenger is safely getting off the vehicle.

In a first aspect, an embodiment of the present invention provides a method for intelligently determining that a passenger is safely getting off the vehicle. The method includes: when detecting that the vehicle stops driving, and the door opening handle is pulled, the voice prompts the passenger to detect the distance within the preset range of the vehicle. Whether there is a moving object; receiving indication information input by the passenger, the indication information is used to indicate whether there is a moving object within a preset range of the vehicle; and when the indication information is negative information, the door is unlocked to facilitate the passenger to open the door and get off the vehicle; or, when When the indication information is the confirmation information, the control door continues to be locked until the passenger inputs a negative message, and the control door is unlocked, wherein the negative information and the confirmation information are input through different input ports.

The method for intelligently determining the safe exit of a passenger provided by the embodiment of the present invention, when the vehicle stops driving, and the passenger does not detect the danger outside the vehicle, the door will be locked. The voice prompts the passenger to observe whether there is a moving obstacle outside, and judge whether the obstacle exists to pose a danger to the passenger getting off the vehicle safely. The door will automatically lock until the negative information entered by the passenger. The door is automatically unlocked until the passenger enters a negative message. The passenger gets off safely, and the negative information is mainly used to indicate that there is no moving object within the preset range of the vehicle. Through the above method, passengers can be safely taken off at any time. In particular, the safety awareness of passengers is avoided, and the driver is not conscious of the “danger of getting off” caused by the passengers.

Further, when the number of times the unlocked door is counted is greater than the first time threshold, the number of times the door is unlocked is cleared and recounted, wherein the first threshold is an even number.

In the above embodiment, in order to prevent the number of unlocking of the door from being too large, the number of statistical times is too large. The number of times the door is unlocked may be cleared when the number of times the door is unlocked is greater than the first number of thresholds.

In a second aspect, the present invention provides an apparatus for intelligently determining that a passenger is safely getting off the vehicle, the apparatus comprising: a detecting unit configured to detect whether the open handle of the door is pulled when the vehicle stops driving;

a voice prompting unit, configured to: when the detecting unit detects that the door open handle is pulled, the voice prompts the passenger to detect whether there is a moving object within a preset range of the vehicle;

a receiving unit, configured to receive indication information input by the passenger, where the indication information is used to indicate whether there is a moving object within a preset range of the vehicle;

The processing unit is configured to control the unlocking of the door when the indication information is negative information, so that the passenger can open the door and get off the vehicle;

Alternatively, when the indication information is the confirmation information, the control door continues to be locked until the passenger inputs a negative message, and the door is unlocked, wherein the negative information and the confirmation information are input through different input ports.

The device for intelligently determining the safe exit of the passenger provided by the embodiment of the present invention uses the detecting unit to detect whether the open handle of the door is pulled when the vehicle stops driving. If it is detected that the door opening handle is pulled, the voice prompting unit prompts the passenger to determine whether there is a moving object within the preset range of the vehicle. Only when the receiving unit receives the negative information, the processing unit will control the door to automatically unlock, otherwise the door will remain locked. Through the device, it is possible to ensure that the passenger can safely get off the vehicle under any circumstances, in particular, the safety awareness of the passenger is weak, and the driver is not consciously reminding the passenger of the "danger of getting off the vehicle".

Further, the counting unit is further configured to: when the counted number of unlocking the door is greater than the first time threshold, clear the number of times the door is unlocked, and re-count, wherein the first threshold is an even number .

Detailed ways

In the following description, for purposes of illustration and description However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the invention.

FIG. 1 is a structural diagram of a system for intelligently determining passengers to get off safely according to an embodiment of the present invention. Specifically, as shown in FIG. 1, the system includes at least an in-vehicle sensor 10, a voice prompting device 20, a CAN bus 30, and a processor 40.

The in-vehicle sensor 10 is configured to detect whether the door opening handle is pulled when the vehicle is stopped. The voice prompting device can be used to prompt the passenger to detect whether there is a moving object within a preset range of the vehicle (for example, a circumference of 200 meters) when the sensor detects that the door opening handle is pulled. When the processor receives the indication of the passenger input through the CAN bus, if the indication information indicates that there is no moving object within the preset range of the vehicle, the door is unlocked. Otherwise, if the indication information is a confirmation message, that is, when the indication information indicates that there is a moving object within a preset range, the door will continue to be locked. The door is unlocked until the passenger enters a negative message. Of course, in order for the system to better distinguish whether the passenger input is a confirmation message or a negative message, the two types of information can be received through two different input ports.

Through the above system, when the passenger gets off the vehicle, the passenger is reminded to pay attention to the movement state of the pedestrian or the vehicle outside the vehicle, and to avoid personal injury caused by collision with another person or the vehicle when getting off the vehicle. Remind passengers to pay attention to safety in real time, and also help passengers develop good behavior habits and enhance safety awareness.

Preferably, as shown in FIG. 2, FIG. 2 is a structural diagram of another system for intelligently determining passenger safety and getting off the vehicle according to an embodiment of the present invention.

If there is a moving object outside the vehicle, such as a person or a vehicle, the system can determine the traveling speed of the moving object and the distance from the vehicle. A more accurate judgment at this time will be dangerous if the passenger gets off the bus. Thus, in this figure, in addition to all of the devices shown in FIG. 1, a speed sensor 50 may be included in the system for determining the speed of the moving object and the current position of the moving object. For example, a radar detector. A Global Positioning System (GPS) 60 is used to detect the current position of the vehicle. The memory 70 is configured to store a preset hazard level standard. The processor 40 can determine the hazard level of the moving object and the like according to the moving speed of the moving object, the distance between the current position of the moving object and the position of the vehicle, and the preset hazard level criteria.

Further preferably, if the vehicle is a taxi, the system may also include a timer 80, a wireless communication device (e.g., GPRS module) 90, and the like. The timer 80 can count passengers' boarding time and getting off time. The wireless communication device 90 can establish a communication connection with the remote server for uploading the current location of the vehicle, the passenger boarding time, the departure time, and the unlocking information of the vehicle to the server. In order for the server to count the frequency of the passengers in the area to which the current location of the vehicle belongs, and the time period in which the frequency of the passengers riding the taxi is greater than or equal to a first threshold (for example, 50 times or more in 10 minutes). The time when the passenger gets into the car is the door lock time, and the time of getting off is the door unlock time. And, the communication command sent by the server is received by the wireless communication module, and is used to indicate that the taxi arrives at a predetermined area or a predetermined position to pick up passengers and the like.

Through the system, not only the safety behavior of passengers getting on and off the vehicle is ensured, but also the frequency, time period and the like of the passengers carrying the passengers can be indirectly counted. Therefore, it is possible to determine the peak time, high-frequency area, etc. of the passengers, so that the taxi company can arrange more taxis during peak hours or high-frequency areas, and facilitate passengers to travel while increasing the economic benefits of the taxi company.

FIG. 3 is a schematic flowchart of a method for intelligently determining passengers safely getting off the vehicle according to an embodiment of the present invention. Specifically, as shown in FIG. 3, the method includes:

Step 310: When detecting that the vehicle stops driving and the door opening handle is pulled, the voice prompts the passenger to detect whether there is a moving object within a preset range of the vehicle.

Specifically, when the system detects that the vehicle has stopped driving, and the door opening handle is pulled. Then, the system will use voice prompts to remind passengers to check if there is any movement within the preset range of the vehicle (for example, within a radius of 200 meters, the most important is to see within 200 meters behind the vehicle). object.

Step 320, receiving indication information input by the passenger.

Specifically, when the passenger checks whether there is a moving object within the preset range of the vehicle according to the voice prompt, the indication information is input into the system. In general, the system can include two input ports for receiving indication information, one for receiving negative information and one for receiving confirmation information. The indication information is used to indicate whether there is a moving object within a preset range of the vehicle.

When the indication information received by the system is negative, the door is unlocked. It is convenient for passengers to open the door and get off. Otherwise, the door continues to lock. The door is unlocked until the passenger enters a negative message.

The method for intelligently determining passengers to get off the vehicle is provided. When detecting that the passenger needs to get off the vehicle, the passenger is promptly reminded to detect whether there is a moving object within the preset range of the vehicle, which may pose a danger for the passenger to get off the vehicle. When the passenger determines that there is no danger, the door automatically unlocks the vehicle, otherwise the door is locked. Until the passengers determine that there is no danger. Through the above method, passengers can be safely taken off, and unnecessary personal injury and property loss can be avoided. At the same time, the safety awareness of passengers is improved invisibly.

FIG. 4 is a schematic flow chart of another method for intelligently determining passengers safely getting off the vehicle according to an embodiment of the present invention. In order to avoid the inaccuracy of the passenger's subjective judgment, the danger of the passenger getting off the vehicle occurs. Moreover, it is generally the case that the vehicle is usually behind the vehicle, and it is not convenient for the passengers in the vehicle to see if there is a moving object behind the vehicle. Moreover, even if it is determined that there is a moving object behind the vehicle, it may not be very accurate to subjectively determine the speed and distance of the moving object behind the vehicle. This leads to danger.

Therefore, in the present embodiment, when it is detected that the vehicle stops traveling and the door opening handle is pulled, the following steps can be performed. As shown in Figure 4, it includes:

Step 410: When detecting that the vehicle stops driving and the door opening handle is pulled, it is automatically detected whether there is a moving object behind the vehicle.

Specifically, when the system detects that the vehicle has stopped driving, and the door opening handle is pulled. Then, the system will automatically detect if there is a moving object behind the vehicle.

Step 420, when it is determined that there is a moving object behind the vehicle, the hazard level of the moving object is determined according to the moving speed of the moving object and the distance between the current position of the moving object and the position of the vehicle.

Specifically, when it is determined that there is a moving object behind the vehicle, the speed of the moving object and the current position of the moving object may be first determined. Also determine the current position of the door. And calculate the distance between the vehicle position and the current position of the moving object. Finally, the hazard level of the moving object is determined according to the speed of the moving object, the distance between the current position of the moving object and the position of the vehicle.

The specific process for determining the hazard level of a moving object is shown in FIG. The method includes:

When the moving speed of the moving object is less than the first speed, and the distance between the current position of the moving object and the vehicle position is equal to the preset distance (in the present invention, the preset distance refers to the maximum distance that the distance sensor can detect, in the following When the description will not be repeated, the hazard level of the moving object is determined to be the first hazard level;

Determining that the dangerous level of the moving object is the second risk level when the moving speed of the moving object is greater than or equal to the first speed and less than the second speed, and the distance between the current position of the moving object and the vehicle position is equal to the preset distance;

When the moving speed of the moving object is greater than or equal to the second speed, and the distance between the current position of the moving object and the vehicle position is equal to the preset distance, determining that the dangerous level of the moving object is the third dangerous level, wherein the preset dangerous level is The second hazard level, the third hazard level is the highest hazard level.

In step 430, when the dangerous level of the moving object is lower than the preset hazard level, the door is automatically unlocked.

Among them, the preset hazard level is the second hazard level, and the third hazard level is the highest hazard level. That is, if the dangerous level of the moving object is lower than the second dangerous level, the door can be automatically unlocked to facilitate the passenger to get off the vehicle.

Step 440: When the dangerous level of the moving object is higher than or equal to the preset dangerous level, calculate the time when the moving object arrives at the door according to the moving speed and the distance between the current position of the moving object and the position of the vehicle, and start timing.

Specifically, if the distance between the current position of the moving object and the position of the vehicle is S, and the moving speed is V, then the time when the moving object reaches the door

From this moment on, until the time is greater than t, it can be determined that the moving object has exceeded the vehicle.

It is now only possible to determine that the detected moving object has exceeded the vehicle position or is passing the vehicle position. However, it is not entirely certain that the passenger is safe to get off at this time. It is very likely that moving objects behind the vehicle will threaten passenger safety.

Therefore, the method further includes a step 450 of detecting whether there is a moving object behind the vehicle when the timing is greater than the time when the moving object arrives at the vehicle door.

Preferably, in general, if the distance between two adjacent moving objects is small, for example, phase The two adjacent vehicles, when the preceding vehicle has passed the door, then the rear vehicle should also be located not far from the door. At this time, in order to reduce the amount of calculation. When the chronograph time is greater than the time when the moving vehicle arrives at the vehicle door of the passenger, the voice prompt can be used to remind the passenger to determine whether there is still a vehicle passing by. When the passenger determines that there is no vehicle passing behind, after inputting a negative message, the door is unlocked. It is convenient for passengers to get off. If the passenger enters the confirmation message, that is, the vehicle movement still exists at the rear, and the position of the vehicle is slightly far away, the passenger cannot accurately determine whether the vehicle will be dangerous at this time, then the system will detect the rear movement again. The distance between the vehicle position and the position of the vehicle where the passenger is located, and the speed of the vehicle moving rearward, the hazard level is determined again based on these two parameters. Different treatments are made according to different hazard levels.

By the above method, it is detected again whether or not there is a moving object behind the vehicle. If there is a moving object, the danger level of the moving object is determined based on the speed of the moving object and the distance between the current position of the moving object and the position of the vehicle. The control door is automatically unlocked until it is determined that there is no moving object behind the vehicle, or the dangerous level of the moving object existing behind the vehicle is lower than the preset hazard level.

An embodiment of the present invention provides a method for intelligently determining that a passenger is safely getting off the vehicle. When detecting that the passenger needs to get off the vehicle, detecting whether there is an object within a preset range of the vehicle, and if it is determined that there is a moving object, according to the speed and distance of the moving object. The distance between the current position of the vehicle, determine the hazard level of the moving object, and determine whether to unlock immediately according to the hazard level, so that the passenger can get off the vehicle; or start timing, when it is determined that the hazard has been eliminated, it is automatically unlocked to facilitate the passenger to get off. In this way, passengers can be safely removed. Avoid unnecessary personal injury and property damage. At the same time, the safety awareness of passengers is improved invisibly.

FIG. 6 is a schematic flow chart of another method for intelligently determining passengers safely getting off the vehicle according to an embodiment of the present invention.

Based on the above several embodiments, if the vehicle is a taxi, the method can also count the peak time period during which the passenger usually rides, the specific area where the passenger is more, and the like according to the time period and frequency of the passenger getting on and off the vehicle. In order to facilitate the taxi company to arrange the layout of the taxi according to different time and different regions. This technical solution is implemented, for example, on the basis of the previous embodiment. In addition, in addition to the above steps 410 to 450 (labeled as steps 610-650 in this embodiment), the embodiment may further include:

In step 660, the number of times the door is unlocked is counted.

In step 670, when the number of unlocking of the door is an odd number of times, it is determined that the passenger gets on the vehicle, and the position information and the boarding time when the passenger gets on the vehicle are recorded.

At step 680, the location information and the boarding time when the passenger gets on the vehicle are uploaded to the server.

Specifically, the current location information of the vehicle, the passenger boarding time information may be uploaded to the server through a wireless communication network, such as a GPRS network, or other communication methods, such as 3G, 4G, 5G, and the like. In order to enable the server to calculate the frequency of picking up passengers of the taxis in different time periods and different regions according to the above parameter information uploaded by the vehicle. Indirectly obtain the peak hours of taxis in different areas. And which regional passengers take the taxi more frequently than other regions and many more. The statistical results are transmitted to the service platform or control center of the taxi. In order to enable the taxi company's staff to reasonably arrange the distribution of taxis at different times and in different regions based on the results of the feedback from the server. In turn, the economic benefits of taxis are increased, and costs are reduced.

Another method for intelligently determining passengers to safely get off the vehicle provided by the embodiment of the present invention can also indirectly count the peak time period of the passengers riding the taxi and the area with a high frequency of the taxi when the passenger can safely get off the vehicle. and many more. In turn, it is convenient for the taxi company to realize the overall layout of the taxi based on the statistical results. Under the premise of reducing work costs, improve economic efficiency.

FIG. 7 is a schematic flowchart of another method for intelligently determining passengers to get off the vehicle safely according to an embodiment of the present invention. Specifically, as shown in FIG. 7 , the method may further include:

Step 790: Receive a communication instruction sent by the server.

Specifically, the communication command is sent by the server to the terminal after the time period when the passenger in the preset time period is in the time zone when the passenger gets on the vehicle belongs to the area where the passenger rides the taxi, and the frequency of the passenger rides the taxi is greater than or equal to the first threshold. And the communication instruction is used to indicate that the taxi arrives at the predetermined area to pick up the passenger in the first time period, wherein the first time period is a time period in which the frequency of the passenger riding the taxi is greater than or equal to the first threshold, the predetermined period The area is an area in which the frequency of the ride is greater than the first frequency threshold.

After the server counts the passenger ride frequency in different areas at different times, the number of taxis in different areas can be adjusted in real time. The passenger can also send a ride request to the server through the mobile terminal through wireless communication means or other means of communication. The request includes the current location information of the passenger. After receiving the ride request sent by the passenger, the server searches for a nearby taxi that is idle, and sends a communication command to the taxi to indicate that the taxi arrives at the location to pick up the passenger. Or, the server will also calculate in real time which area has been or is expected to increase the number of passengers in a certain period of time. Then, a communication instruction is sent to the taxi that is free in the nearby area, indicating that the taxi arrives at the predetermined area to pick up or prepare to pick up the passenger.

After receiving the communication command sent by the server, each taxi will arrive at a predetermined area or a predetermined location to pick up the passenger.

In addition, in any of the embodiments corresponding to FIGS. 6 and 7, in order to prevent the taxi vehicle from counting the number of times the door is unlocked is too large, an unnecessary burden is placed on the processor. Therefore, in the method step described in FIG. 6 or FIG. 7, the method may further include:

In step A, when the counted number of unlocked doors is greater than the first threshold, the number of times the door is unlocked is cleared to zero. Wherein, the first threshold is an even number.

In addition, in the above several embodiments, when judging the danger level of the moving object, it is always emphasized that the distance between the current position of the moving object and the vehicle position is equal to the preset distance: The range in which the sensor generally detects the distance is limited. Therefore, when determining the level of danger, the distance between the detected moving object and the position of the vehicle is equal to the maximum distance that the sensor can detect, that is, the preset distance.

Correspondingly, corresponding to the method for intelligently determining the safe exit of the passenger shown in FIG. 3, the embodiment of the present invention further provides an apparatus for intelligently determining that the passenger is safely getting off the vehicle. FIG. 8 is a schematic structural diagram of an apparatus for intelligently determining that a passenger is safely getting off the vehicle according to an embodiment of the present invention.

Specifically, when the detecting unit 801 detects that the vehicle has stopped running, and the door opening handle is pulled. Then, the voice prompting unit 802 will issue a voice prompt to remind the passenger to check the distance within the vehicle range before the door is opened (for example, within a range of 200 meters in radius, the most important is to look within 200 meters behind the vehicle) Whether there is a moving object.

The receiving unit 803 is configured to receive indication information input by the passenger.

Specifically, when the passenger checks whether there is a moving object within the preset range of the vehicle according to the voice prompt issued by the voice prompting unit 802, the indication information is input to the device that intelligently determines that the passenger is safely getting off the vehicle. In general, the apparatus can include two receiving units 803 that receive indication information, one for receiving negative information and one for receiving confirmation information. The indication information is used to indicate whether there is a moving object within a preset range of the vehicle.

The processing unit 804 is configured to: when the indication information is negative information, the door is unlocked, so that the passenger can open the door and get off the vehicle;

The device for intelligently determining the safe exit of the passenger is provided by the embodiment of the present invention. When the detecting unit detects that the passenger needs to get off the vehicle, the voice prompting unit promptly reminds the passenger to detect whether there is a moving object within the preset range of the vehicle. It is dangerous for passengers to get off. When the passenger determines that there is no danger, the processing unit will control the door to automatically unlock, so that the passenger can get off the vehicle; otherwise, the door is locked. Until the passengers determine that there is no danger. Through the above device, it is possible to ensure that passengers get off the vehicle safely and avoid unnecessary personal injury and property damage. At the same time, the safety awareness of passengers is improved invisibly.

Another embodiment of the present invention further provides an apparatus for intelligently determining that a passenger is safely getting off the vehicle, and the apparatus corresponds to a method for intelligently determining that a passenger is safely getting off the vehicle shown in FIG. Specifically, as shown in FIG. 9, the apparatus includes: a detecting unit 901, a processing unit 902, and a timing unit 903.

When the moving speed of the moving object is less than the first speed, and the distance between the current position of the moving object and the vehicle position is equal to the preset distance, determining that the dangerous level of the moving object is the first dangerous level;

When the processing unit 902 determines that the dangerous level of the moving object is lower than the preset hazard level, the control door is automatically unlocked.

When the processing unit 902 determines that the dangerous level of the moving object is higher than or equal to the preset dangerous level, the time at which the object reaches the vehicle door can be moved according to the moving speed and the distance between the current position of the moving object and the vehicle position, and timing is started.

The timing unit 903 will start timing at this time.

From this moment on, until the timing unit 903 counts time is greater than t, it can be determined that the moving object has exceeded the vehicle.

The detection unit 901 can now only determine that the detected moving object has exceeded the vehicle position or is passing the vehicle position. However, it is not entirely certain that the passenger is safe to get off at this time. It is very likely that moving objects behind the vehicle will threaten passenger safety.

Preferably, the device further comprises: a voice prompting unit 904.

In general, if the distance between two adjacent moving objects is small, for example, two adjacent vehicles, when the preceding vehicle has passed the door, then the following vehicle should also be located not far from the door. . At this time, in order to reduce the amount of calculation. When the chronograph time is greater than the time when the previously moving vehicle arrives at the vehicle door of the passenger, the voice prompting unit 904 may perform a voice prompt to remind the passenger to determine whether there is still a vehicle passing by. When the passenger determines that there is no vehicle passing behind, after inputting a negative message, the processing unit 902 controls the door to unlock. It is convenient for passengers to get off. If the passenger inputs the confirmation information, that is, the vehicle movement still exists at the rear, and the position of the vehicle is slightly far away, the passenger cannot accurately determine whether the vehicle will be dangerous at the time, then the detecting unit 901 will detect the rear again. The distance between the moving vehicle position and the position of the vehicle where the passenger is located, and the speed of the vehicle moving rearward, the processing unit 902 determines the danger level again based on the two parameters. Different treatments are made according to different hazard levels.
