Further, before implementing the traffic accident early warning and protection method of the embodiment, a plurality of early warning reminding and protection strategies need to be set in the vehicle-mounted control terminal of the automobile; the early warning reminding and protecting strategy is set according to the degree of damage caused by the traffic collision accidents, and the degree of damage can be determined according to historical traffic collision accidents.
When the hazard degree is determined, the hazard degrees corresponding to a plurality of input traffic collision accidents can be obtained, and then early warning reminding and protection strategies are determined according to the input hazard degrees; for example, a plurality of historical traffic collision accidents are obtained, historical hazard levels are set according to hazard degrees corresponding to the historical traffic collision accidents, and then early warning reminding and protection strategies are set according to the historical hazard levels.
That is, in one implementation manner of the present embodiment, step 100 includes the following steps before:
and 001, acquiring the hazard degrees corresponding to a plurality of traffic collision accidents, and setting corresponding early warning reminding and protection strategies according to the hazard degrees.

and S200, evaluating the traffic collision accident according to the road traffic participant information and the road auxiliary object information to obtain a corresponding evaluation report.
In this embodiment, after acquiring the information of the road traffic participants and the information of the road auxiliary objects, a processor of the vehicle-mounted control terminal of the automobile is used to evaluate the traffic collision accident, so as to obtain an evaluation report of the traffic collision accident.
Specifically, when the traffic collision accident is evaluated, the road traffic participant information and the road auxiliary object information may be analyzed to obtain probability information, time information, position information, and motion information of a post-collision accident subject of the traffic collision accident.
Further, in analyzing the probability of the traffic collision accident, the probability of collision of road traffic participants other than the current vehicle may be analyzed, for example, the probability of collision between other vehicles, between other vehicles and pedestrians, and between other vehicles and road assistant objects.
Then selecting an object with the highest occurrence probability as a reference object, and taking the probability of the traffic collision accident of the reference object as the probability information of the traffic collision accident; correspondingly, the time information and the position information of the traffic collision accident are the time point and the position point of the occurrence of the traffic collision accident, and the motion information of the post-collision accident main body is the approximate motion track of the reference object after the traffic collision accident.
Further, after obtaining probability information, time information, position information, and motion information of the post-collision accident subject of the traffic collision accident, the evaluation report may be generated according to the probability information, the time information, the position information, and the motion information of the post-collision accident subject; the evaluation report can be uploaded to the cloud end through the vehicle-mounted 5G module for other applications.
Further, in this embodiment, the evaluation report is output as one software module in the algorithm running inside the ADAS controller, and is then sent to the next software module in the algorithm (i.e. the "evaluation of the degree of damage of the accident to the vehicle" module).
That is, in an implementation manner of this embodiment, the step S200 specifically includes the following steps:
step S210, analyzing the road traffic participant information and the road auxiliary object information to obtain probability information, time information, position information and motion information of a post-collision accident subject of the traffic collision accident;
step S220, generating the evaluation report according to the probability information, the time information, the position information, and the motion information of the post-collision accident body.
In this embodiment, when analyzing the road traffic participant information and the road auxiliary object information, a collision algorithm may be obtained, and the road traffic participant information and the road auxiliary object information may be analyzed according to the collision algorithm; the collision algorithm is an algorithm model which is preset in the automobile and obtained after multiple times of collision learning.
Further, the position and time of the potential traffic collision accident are estimated by comprehensively analyzing the road participant information and the road auxiliary object information, so that the occurrence probability is estimated, and the position of the traffic collision accident and the out-of-control motion track of the accident main body are detected.
When calculating the probability of the traffic collision accident, the traffic collision accident may be divided into three types according to the time point of the occurrence of the traffic collision accident: the first is an unforeseen but inevitable traffic accident, the second is an occurred traffic accident, and the third is a chain accident after the traffic accident.
For the first traffic collision accident, estimating the possibility (probability value, more than 0% and less than 100%), time (occurring after a long time), and position (using the coordinates of the automobile as a reference) of the occurrence of the traffic collision accident; the position of the traffic collision accident is also probability information, and the position is accompanied with a certain deviation value;
for a second traffic collision accident, if a collision between a road participant and a road participant is detected by a radar sensor of the automobile, the probability of the accident is 100%, and the position information is exact position information;
for a third traffic collision accident, the accident is marked as an occurred accident, and the motion information of the accident main body (vehicle or pedestrian) is monitored, because the vehicle cannot stop immediately after collision in a high-speed scene, irregular motion may occur, potential hazards are huge, the motion trend of the vehicle needs to be monitored, and preparation can be made for subsequent hazard degree evaluation.
In this embodiment, that is, in an implementation manner of this embodiment, the step S210 includes the following steps:
step S211, acquiring a collision algorithm, and analyzing the road traffic participant information and the road auxiliary object information according to the collision algorithm;
step S212, estimating the occurrence time and the occurrence position of the potential traffic collision accident according to the analysis result, and estimating the occurrence probability of the potential traffic collision accident;
step S213, detecting the occurrence position of the traffic collision accident and the uncontrolled motion trajectory of the accident subject after the collision.
According to the embodiment, probability information, time information, position information and motion information of a post-collision accident main body of the traffic collision accident are analyzed through a collision algorithm, and an evaluation report can be generated according to the probability information, the time information, the position information and the motion information of the post-collision accident main body, so that the hazard level caused by the traffic collision accident can be evaluated according to the evaluation report subsequently.
As shown in fig. 1, in an implementation manner of the embodiment of the present invention, the traffic accident early warning and protecting method further includes the following steps:
and step S300, evaluating the damage degree of the traffic collision accident to the current vehicle according to the evaluation report.
In this embodiment, after the evaluation report of the traffic collision accident is obtained, the degree of harm caused by the traffic collision accident to the current vehicle can be evaluated according to the evaluation report, and then a corresponding early warning reminding and protecting strategy is obtained according to the evaluated degree of harm, so that a driver and passengers in the automobile are reminded and protected in time.
Specifically, when evaluating the hazard level of the traffic collision accident, a hazard level evaluation criterion may be obtained, and then the hazard level caused by the traffic collision accident is evaluated according to the hazard level evaluation criterion and the evaluation report; the harm degree evaluation criterion may be an evaluation criterion preset in the vehicle-mounted control terminal.
Further, since the degree of damage to the vehicle from different traffic accidents is different, the degree of damage to the vehicle is mainly affected by the following factors: the direction of the traffic accident, the distance between the place of the traffic accident and the vehicle, and the speed of the vehicle when the traffic accident occurs.
When the hazard level of the vehicle is evaluated, the hazard level of the traffic accident is evaluated by integrating information of the occurrence of the traffic accident (information such as the probability of occurrence, the position of occurrence, whether an accident subject regularly moves after occurrence, and the like) and the three factors.
Further, the hazard classifications of the vehicle in this embodiment are divided into four hazard classifications: no hazard, hazard level 1, hazard level 2, hazard level 3 (higher level hazard greater).
That is, in an implementation manner of this embodiment, the step S300 specifically includes the following steps:
step S310, obtaining a hazard degree judgment standard;
and step S320, evaluating the damage level of the traffic collision accident to other vehicles according to the damage degree evaluation standard and the evaluation report.
According to the method and the device, the hazard level caused by the traffic collision accident can be evaluated by obtaining the hazard level evaluation standard, and then the corresponding early warning reminding and protection strategy is selected according to the evaluated hazard level, so that the driver and passengers in the current vehicle can be warned in time through the selected early warning reminding and protection strategy.

and S400, acquiring a corresponding early warning reminding and protecting strategy according to the hazard degree, and alarming and/or protecting according to the early warning reminding and protecting strategy.
In this embodiment, after the hazard level caused by a traffic collision accident is evaluated, a corresponding early warning reminding and protection strategy can be obtained according to the hazard level, and then an audible warning and/or a visual warning and/or a tactile warning can be given to a driver and passengers in the current vehicle according to the early warning reminding and protection strategy.
Further, when the alarm needs to be given to the driver and the passengers in the current vehicle, according to the difference of the hazard levels, the alarm can be given in a single or combined alarm mode, for example, when the collision accident with the hazard level of 1 is caused, the alarm is given only in an audible alarm mode; when the collision accident with the hazard level of 2 is caused, the alarm can be given by adopting a visual alarm mode, and the alarm can also be given by adopting a combined mode of visual alarm and audible alarm; and when the collision accident with the hazard grade of 3 grades occurs, the alarm can be given by adopting a touch alarm mode, and the alarm can also be given by adopting a combined mode of touch alarm, visual alarm and auditory alarm.
