Description
Technical Field
The invention belongs to the field of advanced vehicle control systems in intelligent traffic technologies, and particularly relates to an intelligent parking safety passenger-leaving assisting method, system and control method.
Background
With the rapid development of the economic society, the living standard of people is continuously improved, and the keeping quantity of motor vehicles is continuously increased. Meanwhile, the traffic safety risk brought by the motor vehicle is not negligible. Sixty-three provisions of the implementation of the road traffic safety law of the people's republic of China: the door of the vehicle cannot be opened and the passengers cannot get on or off before the vehicle stops stably, and the door cannot be opened or closed to prevent other vehicles and pedestrians from passing. However, in the actual situation, due to general lack of safety awareness of traffic participants, a vehicle driver and a passenger cannot sufficiently observe whether other vehicles and pedestrians are in the side rear or the side rear through a rearview mirror when driving, and a traffic accident caused by sudden driving is rare. In the age of rapid development of internet application, the phenomenon is also aggravated by the rise of the network reservation taxis, and the use of a large number of network reservation taxis means that the frequency of getting on and off the taxi of passengers is more. Moreover, the functions of the network reserved taxis of different vehicle types are different, passengers are not aware of strange vehicles, the danger of blind door opening when getting on or off the vehicle is increased, and the risk probability of traffic accidents caused by blind door opening when the passengers neglect to observe vehicles coming from behind is greatly increased.
Disclosure of Invention
In view of the technical problems in the prior art, the invention provides an intelligent parking safety passenger getting-off assisting method, system and control method thereof, which can avoid collision accidents with other vehicles or pedestrians moving forwards in the side-to-back direction due to a driving door by judging whether the driving door personnel can fully observe the traffic conditions in the side-to-back direction of the vehicle through a rearview mirror, thereby ensuring the road traffic safety.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows:
the invention provides an intelligent parking safety passenger-leaving assisting method, which comprises the following steps:
detecting the running speed of the vehicle;
judging whether the vehicle speed is lower than a preset vehicle speed threshold value or not, and if not, continuously detecting the vehicle running speed; if yes, judging whether the driving action exists, and if not, continuously detecting the running speed of the vehicle; if so, judging whether a person opening the door watches the rearview mirror at the door opening side or not and the time exceeds a preset time threshold, if not, continuously detecting the running speed of the vehicle, and if so, unlocking the safety lock of the corresponding door.
In the intelligent parking safety passenger getting-off assisting method, firstly, whether the vehicle is in a parking state is judged by judging whether the vehicle speed is lower than a preset vehicle speed threshold value. During the running process of the vehicle, the door is always in a locked state. When the vehicle speed is lower than a preset vehicle speed threshold value, the vehicle is determined to be in a parking state; when the vehicle speed is higher than or equal to a preset vehicle speed threshold value, the vehicle is determined not to be stopped or not to be stable. The unlocking of the doors is not allowed when the vehicle is not parked or is not stationary, and the vehicle is in a parked state is a prerequisite condition for allowing the unlocking of the doors. Then, whether the door needs to be unlocked is judged by judging whether the door is opened or not. On the premise that the vehicle stops, if the door opening action is not detected, the driver or the passenger is determined to be only stopping, and the driver or the passenger does not have the intention of getting off or unlocking the vehicle door, so that the vehicle door unlocking operation is not needed; if the door opening action is detected, the driver or the passenger is determined to have the intention of getting off or unlocking the vehicle door, and further safety detection of unlocking the vehicle door is needed. And finally, judging whether the person opening the door looks at the rearview mirror on the door opening side or not and whether the time exceeds a preset time threshold or not, and judging whether the person opening the door pays attention to observe whether a vehicle or a pedestrian moves forwards or not at the side rear part of the door opening side or not. If the door opener is judged to watch the door-opening side rearview mirror and the time exceeds the preset time threshold value, the door opener is judged to sufficiently observe the conditions of pedestrians or vehicles at the rear side of the door-opening side, and the pedestrians or vehicles which can influence the door-opening safety can be safely opened or get off after the condition that the pedestrians or vehicles at the rear side of the door-opening side do not exist; if the door-opening person is judged not to watch the door-opening side rearview mirror or the time does not exceed the preset time threshold, the door-opening person is judged not to observe or insufficiently observe the conditions of the pedestrian or the vehicle at the rear side of the door-opening side, and the door can not be opened or closed safely after the pedestrian or the vehicle which can influence the door-opening safety is confirmed to be not at the rear side of the door-opening side. Only when the door opener sufficiently observes the conditions of pedestrians or vehicles behind the door opening side, the door is allowed to be unlocked if the forced condition is met, so that the door opener can safely open the door or get off the vehicle.
In order to realize the intelligent parking safety passenger getting-off assisting method, the invention designs an intelligent parking safety passenger getting-off assisting system and a control method.

The vehicle state detection module is connected with a vehicle speed sensor and used for judging whether a vehicle is in a stop state or not, the infrared photoelectric sensing module is used for sensing whether a door opening action exists or not, the point of regard detection module is used for capturing sight of a person who opens the door and whether a rearview mirror at the door opening side is watched or not, the safety evaluation module can receive information of the vehicle state detection module, the infrared photoelectric sensing module and the point of regard detection module and determines whether a signal for unlocking the door safety lock is sent to the door lock control module or not, and the door lock control module is used for controlling locking and unlocking the door safety locks at different positions.
The vehicle state detection module detects the vehicle speed through a vehicle speed sensor, when the vehicle speed is lower than a preset vehicle speed threshold value V, the vehicle state detection module sends information that the vehicle is in a stop state to the safety evaluation module, and when the vehicle speed is higher than or equal to the set vehicle speed threshold value V, the vehicle state detection module sends information that the vehicle is in a running state.
The infrared photoelectric sensing module consists of an infrared emitter and an infrared receiver which are arranged on the inner side vehicle door handle and are positioned on the upper side and the lower side or the left side and the right side of the handle, and is used as a starter of the fixation point detection module. When the infrared receiver detects that the infrared signal is blocked, namely when the hand of a person driving the door extends to the position of the door opening handle of the inner side door, the door opening action information is sent to the safety evaluation module, and the corresponding gaze point detection module is started.
The gaze point detection modules are arranged at the rear-view mirrors at the two sides of the front end of the vehicle and the rear-view mirrors at the two sides of the center pillar, and the four gaze point detection modules positioned at the two sides of the vehicle work independently. When the gazing point detection module captures the action of a person opening a vehicle door to gaze the rearview mirror and the duration time exceeds a preset time threshold T, the gazing point detection module sends gazing action information to the safety evaluation module.
And the safety evaluation module sends an instruction signal to the vehicle door lock control module based on information sent by the vehicle state detection module, the infrared photoelectric sensing module and the fixation point detection module. And when the safety evaluation module receives the information that the vehicle is in the stop state, the door opening action information and the watching action information at the same time, determining that the vehicle door can be unlocked.

Based on the intelligent parking safety passenger getting-off auxiliary method, the intelligent parking safety passenger getting-off auxiliary system comprises a vehicle state detection module, an infrared photoelectric sensing module, a fixation point detection module 1, a safety evaluation module and a vehicle door lock control module. The vehicle state detection module is connected with a vehicle speed sensor and used for judging whether a vehicle is in a stop state or not, the infrared photoelectric sensing module is used for sensing whether a door opening action exists or not, the watching point detection module 1 is used for capturing the sight of a door opening person to see whether the door opening side rearview mirror is watched or not, the safety evaluation module can receive the information of the vehicle state detection module, the infrared photoelectric sensing module and the watching point detection module 1 and determine whether a signal for unlocking a door safety lock is sent to the door lock control module, and the door lock control module is used for controlling the locking and unlocking of doors at different positions.
The vehicle state detection module detects the vehicle speed through a vehicle speed sensor, when the vehicle speed is lower than a preset vehicle speed threshold value V, the vehicle state detection module sends information that the vehicle is in a stop state to the safety evaluation module, and when the vehicle speed is higher than the preset vehicle speed threshold value V, the vehicle state detection module sends information that the vehicle is in an operation state.
The infrared photoelectric sensing module is composed of an infrared emitter and an infrared receiver which are arranged on the inner door handle and are positioned on the upper side, the lower side or the left side and the right side of the handle, as shown in fig. 2, and is used as a starter of the fixation point detection module 1.
The gaze point detection modules 1 are installed at the rear-view mirrors on both sides of the front end of the vehicle and the rear-view mirrors on both sides of the center pillar, as shown in fig. 3, and the four gaze point detection modules 1 located on both sides of the vehicle work independently.
And the safety evaluation module sends an instruction signal to the vehicle door lock control module based on the information of the vehicle state detection module, the infrared photoelectric sensing module and the fixation point detection module 1.
And the vehicle door lock control module controls the vehicle door safety lock at the corresponding position to be locked or unlocked after receiving the signal sent by the safety evaluation module.
Based on the above-mentioned intelligent parking safety assistant system, the present embodiment designs a control method of the intelligent parking safety assistant system, and the flow of the method is shown in fig. 1.
Firstly, the starting step of the intelligent parking safety passenger getting-off auxiliary system is as follows: the vehicle state detection module judges whether the vehicle is changed from a parking state to a driving state, if not, the vehicle state detection module keeps the existing state, and if so, the safety evaluation module is started; the safety evaluation module sends a locking signal to the car door lock control module; and after the car door lock control module receives the locking signal, the car door lock control module controls the safety locks of all the car doors to be locked.
In the driving process, the control process of the intelligent parking safety passenger-leaving auxiliary system specifically comprises the following steps: s1: the vehicle state detection module detects the vehicle speed once every preset time interval delta T;
s2: the vehicle state detection module judges whether the vehicle speed is lower than a preset vehicle speed threshold value V, if not, the step S2 is re-entered, if yes, the information that the vehicle is in a stop state is sent to the safety evaluation module, the infrared photoelectric sensing module is started, and the step S3 is entered;
s3: the infrared photoelectric sensing module detects whether the driving door action exists in real time, and if not, the step S2 is re-executed; if so, sending the driving action information to a safety evaluation module, starting a corresponding fixation point detection module positioned on the same side of the door opening handle, and entering the step S4;
when the passenger intends to get off, the handle is extended to the door opening handle on the inner side of the door. When a hand touches a vehicle door handle, an infrared receiver of the infrared photoelectric sensing module cannot receive an infrared signal sent by an infrared transmitter. At this time, the infrared photoelectric sensing module can judge that the passenger makes the action of driving the door.
If the passenger gets off the vehicle by accident, the passenger may extend the hand to the door opening handle on the inner side of the door, so as to trigger the gazing point detection module. Generally, at this moment, a passenger cannot place a hand at a door opening handle for a long time, and if the fixation point detection module cannot be closed in time, the fixation point detection module can be invalid to work for a long time, subsequent programs during door opening are affected, and system program abuse or judgment errors are caused. Therefore, at this time, the infrared photoelectric sensing module further has the following processes:
the infrared photoelectric sensing module judges whether the action of the vehicle door is finished, if so, the corresponding fixation point detection module positioned on the same side of the door opening handle is closed, and if not, the existing state is kept.
S4: the gazing point detection module captures the action of a car door opener gazing at the corresponding rearview mirror on the same side of the door opening handle in real time, judges whether the time for the car door opener to gaze at the corresponding rearview mirror exceeds a preset time threshold T or not, if not, the step S2 is re-entered, if yes, gazing action information is sent to the safety evaluation module, and the step S5 is entered; wherein the preset time threshold T is 1 s;
s5: the safety evaluation module receives the information that the vehicle is in a stop state, the information of the door opening action and the information of the watching action at the same time, and sends an unlocking signal to the door lock control module after safety evaluation;
if the time elapsed from the step S2 to the step S4 is long, the safety assessment module may have a judgment error, for example, when the vehicle is not in a stopped state when the gaze movement information is finally received, and the opening of the door still belongs to a dangerous movement, so the safety assessment module needs to further judge whether the vehicle is completely in a safe state. The specific process comprises the following steps:
the safety evaluation module judges whether the information that the vehicle is in a stop state, the information of the door opening action and the information of the watching action are received at the same time, if not, the door opener does not finish a series of safety actions (steps S2-S4), the safety evaluation module sends a locking signal to the door lock control module to lock the door, and the door opener in the vehicle cannot open the door at the side with potential danger until the safety evaluation module receives the safety signals that the vehicle is in the stop state, the information of the door opening action and the information of the watching action at the same time to send an unlocking signal to unlock the safety lock of the door.
However, in order to avoid that the vehicle door cannot be opened timely in an emergency state which endangers the safety of passengers, and people or property damage is caused, an emergency unlocking step is needed, and the specific process comprises the following steps:
if the safety evaluation module receives a request for unlocking the safety lock, the safety evaluation module sends an unlocking signal to the vehicle door lock control module; if the safety evaluation module receives a request for recovering the safety lock control, the safety evaluation module sends a locking signal to the door lock control module when the condition is met.
When the condition is met, the vehicle state detection module detects that the vehicle starts to run, or the safety evaluation module does not receive the information that the vehicle is in a stop state, the information of the door opening action and the information of the watching action at the same time in the running process of the vehicle.
S6: and after the door lock control module receives the unlocking signal, the door lock control module controls the unlocking of the safety lock of the corresponding door.
After the steps S1-S6, the intelligent parking safety getting-off auxiliary system stops working, and a person opening the door can open the door to get off the vehicle.
It should be understood by those skilled in the art that the present invention is not limited to the exemplary embodiments described above, and any person skilled in the art can substitute or change the technical solution and concept of the present invention within the technical scope of the present invention.
