Detailed Description
The technical scheme of the invention is further elaborated by combining the drawings and the specific embodiments in the specification. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1, an early warning method provided in an embodiment of the present invention includes the following steps:
step S101: when a preset event is monitored, the distance between the vehicle and surrounding vehicles is acquired;
it should be noted that the early warning method provided by the embodiment may be applied to a vehicle, and specifically may be applied to a vehicle mounted device, a vehicle mounted T-BOX, and other devices installed in the vehicle. Here, the vehicle may be a motor vehicle such as an automobile or a non-motor vehicle such as an electric vehicle. In this embodiment, the early warning method is applied to a vehicle of a vehicle, and the vehicle is an automobile. The surrounding vehicle may refer to a vehicle with the vehicle as a center and a radius as a set distance range, and the set distance may be 3 meters, 10 meters, and the like. In practical applications, the surrounding vehicle may refer to a front vehicle, i.e., a vehicle located in front of the own vehicle, a rear vehicle, i.e., a vehicle located behind the own vehicle, a left side vehicle, i.e., a vehicle located on the left side of the own vehicle, or a right side vehicle, i.e., a vehicle located on the right side of the own vehicle. It should be noted that the front vehicle and the rear vehicle are respectively located on the same lane as the host vehicle, the left vehicle is located on an adjacent left lane of the lane where the host vehicle is located, and the right vehicle is located on an adjacent right lane of the lane where the host vehicle is located. Here, when the surrounding vehicle includes a plurality of vehicles, a vehicle closest to the host vehicle is taken as a surrounding vehicle of the host vehicle. For example, taking the surrounding vehicle as a rear vehicle as an example, when there are a plurality of vehicles behind the host vehicle, a vehicle closest to the host vehicle among the plurality of vehicles is taken as the rear vehicle.
Here, it can be that the volume of the sound that sudden braking, loudspeaker sent is greater than preset volume threshold value etc. to predetermine the event, it is corresponding, monitor and predetermine the event, can be that the sudden braking event appears in detecting this vehicle in normal forward driving process, also can be that the volume that the sound that detects this vehicle sent is greater than first volume threshold value or the volume that receives the sound that loudspeaker of surrounding vehicle sent is greater than second volume threshold value etc. first volume threshold value and second volume threshold value can set up according to actual conditions, for example can set up first volume threshold value as 100 decibels, set up second volume threshold value as 95 decibels etc.. It can be understood that, in the normal forward driving process of a driving vehicle, when a vehicle ahead of the driving vehicle is suddenly braked or stopped, or the vehicle is suddenly inserted into the front of the driving vehicle from an intersection or the like, in order to avoid the vehicle and avoid a traffic accident, an emergency braking measure such as sudden braking is usually taken for the driving vehicle, and at this time, the traffic accident may also be caused due to the limitation of the operation reaction speed of the driving vehicle, the failure of the surrounding vehicles to avoid the driving vehicle in time, and the like. In addition, when a driver encounters a situation that a vehicle suddenly inserts into the front of the vehicle from a position such as an intersection or the like or a vehicle behind the vehicle is out of control or cannot stop due to too high speed in a normal forward driving process of the vehicle, in order to avoid the vehicle and avoid a traffic accident, the driver usually reminds surrounding vehicles of avoiding by using a horn to sound the vehicle or reminds the vehicle of avoiding by using a horn to sound the surrounding vehicles, and at the moment, the traffic accident may also be caused due to the reasons that windows of the vehicle are closed and the driver does not notice horn sound. Here, whether the detection vehicle has a sudden braking event or not CAN be judged by reading the running state information of the vehicle through a CAN bus, and the volume of the sound emitted by a horn of the detection vehicle CAN be acquired through a decibel meter or the existing volume measurement technology.
Here, the distance between the host vehicle and the surrounding vehicle may be acquired by an infrared technique, a radar ranging technique, a camera, or the like. Taking the example that the surrounding vehicle includes a rear vehicle and the preset event includes a sudden brake, in an embodiment, the step of obtaining the distance between the vehicle and the surrounding vehicle includes: triggering the reversing radar of the vehicle to start, and acquiring the distance between the vehicle and a rear vehicle through the reversing radar of the vehicle. Here, the process of obtaining the distance between the vehicles by the reversing radar of the vehicles may be known from the prior art, and will not be described herein. It is understood that if the distance between the vehicle and the vehicle ahead is measured, a radar may be provided in the front of the vehicle body; if the distance between the vehicle and the left vehicle is measured, a radar can be arranged at the left side part of the vehicle body of the vehicle; if the distance between the vehicle and the right vehicle is measured, a radar may be provided on the right side of the vehicle body. So, directly acquire the distance with the rear vehicle through the radar of backing a car of vehicle, not only measuring speed is fast, and the degree of accuracy is also high moreover, has further promoted user and has used experience.
In an embodiment, the method may further comprise: and triggering the reversing radar of the vehicle to be turned off after detecting that the running speed of the vehicle is greater than a preset speed threshold value. It can be understood that, in the case of a traffic accident such as a vehicle rear-end collision, it is generally easy to occur on a congested road segment, where the running speed of the vehicle is low, but a sudden-high and sudden-low situation may occur, that is, the vehicle suddenly accelerates at a certain moment and suddenly decelerates at another moment. The preset speed threshold value can be set according to the actual situation, for example, 15km/h, 20km/h and the like, if the running speed of the vehicle is greater than the preset speed threshold value, it can be considered that the road condition may not be congested at this time, the possibility of rear-end collision is reduced, and the distance between the vehicles does not need to be measured in real time at this time, so that the reversing radar of the vehicle is triggered to be turned off. Therefore, the reversing radar of the vehicle is turned off in time, so that the electric quantity consumption is saved, and the service life of the reversing radar is prolonged.
Step S102: and when the distance is smaller than a preset first distance threshold value, sending out an early warning message.
Specifically, when the distance between the vehicle and the surrounding vehicles is smaller than a preset first distance threshold, an early warning message is sent out to warn the driver. The early warning message may be set according to actual needs, for example, the early warning message may be a sound, a text, or the like.
It is understood that the first distance threshold may be set according to actual requirements, for example, may be set to 2 meters, 4 meters, and the like. In addition, in order to more accurately characterize the safe vehicle distance between the host vehicle and the surrounding vehicle, the first distance threshold value may be determined according to the safe vehicle distance, when the surrounding vehicle is the rear vehicle, the braking distance of the rear vehicle, which is the distance required by the rear vehicle from the start of emergency braking to the stop of the vehicle, may be estimated according to the vehicle speed information of the rear vehicle, the type and performance parameters of the rear vehicle, and the like, and the first distance threshold value may be determined according to the braking distance, such as directly using the braking distance as the corresponding first distance threshold value.
In one embodiment, the sending out the warning message includes:
sending a set voice early warning message to a sound generating device arranged in the vehicle so that the sound generating device plays the voice early warning message; wherein the voice warning message includes the distance; alternatively, the first and second electrodes may be,
sending the set character early warning message to a display device arranged at the tail of the vehicle so as to enable the display device to display the character early warning message; wherein the text early warning message includes the distance.
It will be appreciated that the sound generating means may be a speaker or the like capable of playing a voice message. The sound generating devices are arranged at the positions of the vehicles and the corresponding quantity can be set according to actual requirements. In practical applications, the sound generating device may be a speaker existing in a vehicle. The voice early warning message can be set according to the actual situation, for example, the voice early warning message can be set to be '2 meters away from the rear vehicle, please grip the steering wheel with both hands', '2 meters away from the rear vehicle, please accelerate away from the rear vehicle', and the like, so that the driver of the vehicle is early warned to prevent rear-end collision. Therefore, the voice early warning message set by the sound generating device arranged in the vehicle is played, the real-time distance between the driver and the rear vehicle is informed, the driver is reminded of paying attention to the prevention of rear-end collision, and the driving safety is improved.
It will be appreciated that the display device may be a display screen or the like capable of displaying text messages. The display device is arranged at the position of the tail of the vehicle and the corresponding number of the display device can be set according to the actual situation. The text early warning message can be set according to the actual situation, for example, the text early warning message can be set to information such as ' 2 meters away from the front vehicle, please decelerate ', 2 meters away from the front vehicle, please keep the vehicle distance ', and the like, so that the driver of the rear vehicle is reminded to prevent rear-end collision. Therefore, the display device arranged at the tail part of the vehicle displays the set character early warning message to inform the real-time distance between the rear vehicle and the vehicle, so that the rear vehicle is reminded of preventing rear-end collision, and the driving safety is further improved.
In summary, in the early warning method provided in the embodiment, when the preset event is monitored, the distance between the vehicle and the surrounding vehicles is acquired, and when the distance is smaller than the preset first distance threshold, the early warning message is sent out in time to warn the driver, so that the driving safety can be effectively improved.
In an embodiment, when the distance is smaller than a preset first distance threshold, the method further includes, while sending an early warning message:
and acquiring a surrounding image of the vehicle, and storing the surrounding image of the vehicle, wherein the surrounding image of the vehicle comprises the surrounding vehicle information.
It can be understood that, when the distance between the host vehicle and the surrounding vehicle is smaller than the preset first distance threshold, it indicates that the safety risk between the host vehicle and the surrounding vehicle is greater, at this time, a traffic accident is likely to occur between the host vehicle and the surrounding vehicle, and in order to avoid the situation that the information of the vehicle at the origin of the accident cannot be obtained due to the escape of the surrounding vehicle after the traffic accident occurs, or to record in advance the information of whether the driving state of the surrounding vehicle is changing lanes or not, so as to be used as the evidence after the traffic accident occurs, so as to search for the cause of the accident and the like quickly, the information of the surrounding vehicle may be recorded and stored in advance. The surrounding vehicle information may include information on the appearance of the vehicle, such as a vehicle type and a license plate, and may further include driving state information, such as a driving lane of the vehicle. Therefore, the surrounding images of the vehicle containing the surrounding vehicle information are collected and stored, so that the vehicle safety can be effectively managed, and the driving safety is further improved
Here, the peripheral image of the host vehicle may be acquired by a camera or the like, and when the peripheral vehicle is in different directions of the host vehicle, the peripheral image of the host vehicle may be acquired in different ways. In one embodiment, when the surrounding vehicle includes a rear vehicle, the step of acquiring the surrounding image of the own vehicle includes: triggering the rear camera of the vehicle to start, acquiring the rear image of the vehicle shot by the rear camera of the vehicle, and determining the rear image of the vehicle as the surrounding image of the vehicle. Here, the viewing angle range of the rear image of the host vehicle captured by the rear camera of the host vehicle may be set according to actual needs. It is understood that when the surrounding vehicle is a vehicle in a different direction, the manner of acquiring the surrounding image of the own vehicle is also different accordingly. For example, if the surrounding vehicle is a preceding vehicle, the method may trigger a front camera of the host vehicle to start, acquire a front image of the host vehicle captured by the front camera of the host vehicle, and determine the front image of the host vehicle as the surrounding image of the host vehicle. So, directly acquire the surrounding image of this vehicle through the rear camera of vehicle, it is fast to shoot, and convenient operation, has further promoted user and has used experience.
In one embodiment, when the surrounding vehicle includes a rear vehicle, the step of acquiring the surrounding image of the own vehicle includes: triggering the left and right streaming media cameras of the vehicle to start, acquiring the rear images of the vehicle shot by the left and right streaming media cameras of the vehicle, and determining the rear images of the vehicle as the surrounding images of the vehicle. Specifically, for a vehicle with left and right streaming media cameras, the left and right streaming media cameras of the vehicle are triggered to start, so as to obtain rear images of the vehicle, which are shot by the left and right streaming media cameras of the vehicle, and determine the rear images of the vehicle as surrounding images of the vehicle. So, directly through the vehicle about the streaming media camera acquire the surrounding image of this vehicle, it is fast, the shooting range is wide to shoot speed, and convenient operation, further promoted user and used experience.
In one embodiment, the step of acquiring the surrounding image of the own vehicle includes:
and when the distance between the vehicle and the surrounding vehicle is detected to be smaller than a preset second distance threshold, acquiring the surrounding image of the vehicle. It can be understood that, after the distance between the host vehicle and the surrounding vehicle is smaller than the preset first distance threshold, the driver may avoid the vehicle by braking in time, and the distance between the host vehicle and the surrounding vehicle may gradually increase or substantially remain unchanged, and at this time, the risk of occurrence of a traffic accident such as rear-end collision between the host vehicle and the surrounding vehicle is reduced, and therefore, it may not be necessary to obtain the surrounding image of the host vehicle including the surrounding vehicle information. However, if the distance between the host vehicle and the surrounding vehicle continues to decrease, the risk of a traffic accident such as a rear-end collision between the host vehicle and the surrounding vehicle increases, and it is necessary to acquire the surrounding image of the host vehicle including the surrounding vehicle information. The second distance threshold may be set according to actual needs, and when the first distance threshold is 4 meters, the second distance threshold may be set to 2 meters, and the like. Therefore, the surrounding image of the vehicle containing the surrounding vehicle information is acquired only when the distance between the vehicle and the surrounding vehicle is smaller than the preset second distance threshold value, the mode is flexible, the storage space can be effectively saved, and the processing efficiency is improved.
