Detailed Description
As described above, when a vehicle is traveling on a road, a curve is the most dangerous road section, and traffic accidents often occur due to the blocking of the driver's vision, because in the steering scene of the vehicle, there are often some vision blind areas, such as the vision of the vehicle owner is partially blocked before the vehicle turns or enters the curve, and a blind area on the vision is caused. When the vehicle turns, the difference between the front inner wheel and the rear inner wheel is the blind area of the vision of the vehicle owner, and the vehicle head of a relatively long large-sized vehicle such as a truck, a bus and the like turns over, and often the vehicle head is not completely turned over, so that the vision blind area is caused. And when the vehicle turns right or left, the turning angle is large or the lane is changed continuously for more than 2 times, and the dead zone is formed by not clearly seeing the coming vehicles on the lane after turning at all. In the prior art, information in a blind area is generally identified by installing a vehicle body detection radar. However, such radars have a limited detection range and are very susceptible to interference from external factors. In the steering process of a vehicle, the vehicle body detection radar can not timely and accurately find obstacles due to a large number of uncontrollable factors on a road, so that traffic accidents are caused.
In view of this, an embodiment of the present application provides an alarm method in a vehicle steering process, when the method is executed, first, a target vehicle is caused to establish a communication link with a roadside cooperative unit in response to turning on of a steering lamp, so that the roadside cooperative unit receives a road condition sent by a road information acquisition radar, predicts a dangerous object that collides with the target vehicle when the target vehicle is steering according to the road condition, and generates road information; and then, enabling the target vehicle to receive the road surface information sent by the road side cooperative unit, and finally enabling the target vehicle to generate alarm information according to the road surface information so as to alarm. Therefore, the target vehicle receives the road surface information sent by the road side cooperative unit, so that the angle and the range covered by the information acquisition are expanded by the target vehicle, and the accuracy and the timeliness of the dangerous information acquisition of the target vehicle in steering are improved. Therefore, the recognition capability of the target vehicle on the danger in the steering process can be improved, the warning is timely carried out, the potential safety hazard is reduced, and the safety coefficient of vehicle driving is improved.
In order to make the present application solution better understood by those skilled in the art, the following description will clearly and completely describe the technical solution in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
For easy understanding, first, an application scenario of the embodiment of the present application will be described. The warning method in the vehicle steering process can be applied to a target vehicle, a road side cooperative unit and a road surface monitoring radar. The road surface monitoring radar is used for acquiring object information in road monitoring. The road side cooperative unit is used for identifying information acquired by the road surface monitoring radar and extracting road surface information related to the target vehicle. The target vehicle is used for receiving the road surface information provided by the road side cooperative unit, judging whether an obstacle possibly collides with the target vehicle in the steering process of the vehicle, generating alarm information and giving an alarm to a driver. When the vehicle turns, the target vehicle and the road side cooperative unit establish communication, and the road side cooperative unit generates road surface information according to the information collected by the received road surface monitoring radar and sends the road surface information to the target vehicle, and the target vehicle gives an alarm to a driver. Thus, the road surface cooperative unit is used for collecting the road surface information around the vehicle when the vehicle turns, the range and the angle of the information mobile phone can be enlarged, and the safety coefficient of the vehicle when the vehicle turns is improved. Specifically, the target vehicle may perform the steps as described in fig. 1.
Referring to fig. 1, fig. 1 is a flowchart of a method for alarming in a vehicle steering process according to an embodiment of the present application, including:
s101: the target vehicle establishes a communication link with the target roadside coordination unit in response to turning on the turn signal lamp.
The target road side cooperative unit is used for communicating with the road surface monitoring radar, acquiring target vehicle information and road surface conditions around the target vehicle, and providing the information to the target vehicle. The road surface monitoring radar is mainly used for acquiring object information in a monitoring area, and can comprise a traffic control camera, a speed measuring monitoring camera, road side meteorological equipment, road side road environment monitoring equipment and the like. Of course, the target road side cooperative unit can also communicate with terminals such as traffic lights and electronic signs to acquire road information, and normal operation of the embodiment of the application is not affected.
Alternatively, the target vehicle may be brought into communication with the roadside coordination unit by: first, the target vehicle broadcasts a communication link signal in response to turning on of the turn signal, and detects a plurality of roadside cooperative units around the target vehicle. Then, the target vehicle judges the distance between the circuit-side cooperative unit and the vehicle, and selects the target circuit-side cooperative unit closest to the target vehicle as the target circuit-side cooperative unit. The target road side cooperative unit allocates an idle communication link resource and a communication ID to the target vehicle, and establishes a communication link.
S102: the target vehicle receives the road surface information sent by the target road side cooperative unit.
Wherein the road surface information includes information about an obstacle present in the steering of the target vehicle. Wherein the obstacle-related information may include: information such as the type of obstacle around the vehicle, the distance of the obstacle from the target vehicle, the volume of the obstacle, and the degree of danger of the obstacle, for example, the type of obstacle may be pedestrians, vehicles, traffic cones, or the like, and the degree of danger may be no danger, general danger, collision danger, or the like.
Optionally, after the target roadside coordination unit establishes a communication link with the target vehicle, the road condition sent by the road detection radar is received first. Then, the target roadside cooperation unit identifies road surface information related to the target vehicle from the received road surface information. Then, the identified road surface information is transmitted to the target vehicle so that the target vehicle alarms according to the road surface information received by the target vehicle. The road surface condition may include, among other things, information of a vehicle movement condition behind the target vehicle, whether an obstacle exists in front of or around the target vehicle, whether the road surface on which the target vehicle is traveling is damaged, and the like. In some possible implementations, the roadside coordination unit may continuously calculate the possibility of collision of the target vehicle according to the road surface condition, and if an obstacle is found to possibly collide with the target vehicle, collect the obstacle information and generate road surface information, and send the road surface information to the target vehicle in steering. Of course, the road side cooperative unit can also find that the road of the target vehicle turns to have different shapes according to the road surface condition, such as different shapes of road surface collapse and the like, generate road surface information, and send the road surface information to the target vehicle, and the normal implementation of the embodiment of the application is not affected.
S103: and the target vehicle generates alarm information according to the road surface information and alarms.
The warning information may include obstacle information, estimated collision time, estimated collision position, estimated collision degree, and the like. Optionally, the target vehicle may select an alarm mode according to the alarm information, for example, the alarm information may be projected on a windshield of a front window by using a screen projection device, if different obstacle types may be displayed by using different icons, different collision positions may display distances between the obstacle and the target vehicle by using an obstacle distance scale, and a danger prompt sound may be generated by using a vehicle instrument panel according to the urgency degree or the estimated collision degree of the collision time. In some possible implementation manners, other warning manners, such as displaying the estimated collision degree by using different colors, are adopted, and normal implementation of the embodiment of the application is not affected.
Alternatively, the target vehicle may generate the alert information by: and the target vehicle obtains barrier information according to the road surface information, and then obtains a barrier estimated track according to the barrier information. The target vehicle obtains a vehicle estimated track according to the vehicle motion information, and then obtains alarm information according to the obstacle estimated track and the vehicle estimated track.
In some possible implementations, the target vehicle may obtain at least one estimated collision point information according to the obstacle information and the estimated trajectory of the vehicle, where the estimated collision point information includes a collision time point, a collision position, and a collision degree of the target vehicle with the obstacle. And then, obtaining corresponding collision information according to the estimated collision point information, wherein the collision information comprises the duration between the time when the corresponding collision point collides with the current time of the target vehicle and the distance between the time when the corresponding collision point collides with the current position of the target vehicle. And finally, generating alarm information by the target vehicle according to the estimated collision point information and the corresponding collision information.
Optionally, the target vehicle may further evaluate the alert level of the alert information according to a duration between when the corresponding collision point in the alert information collides with the current time of the target vehicle and a distance between when the corresponding collision point collides with the current position of the target vehicle. If the warning level reaches the predetermined range, the target vehicle gives a warning. For example, if the duration of the collision with the current time is less than 5 seconds and the distance between the position of the collision and the current position is less than 10 meters, the warning level is particularly dangerous, the target vehicle triggers an audible alert and a red sign is projected on the front window windshield of the vehicle to alert the driver.
According to the method and the device, the target vehicle receives the road surface information sent by the road side cooperative unit, so that the angle and the range covered by the information acquisition around the vehicle in the vehicle steering process are expanded, and the accuracy and the timeliness of dangerous information acquisition in the vehicle steering are improved. The method effectively improves the dangerous recognition capability when the vehicle turns, can provide warning information for a driver timely and accurately, and reduces the potential safety hazard existing in the blind area when the vehicle turns.
In the embodiment of the present application, there are a plurality of possible implementations of step S103 described in fig. 1, and the following description will be given. It should be noted that the implementations presented in the following description are only exemplary and not representative of all implementations of the embodiments of the present application.
Referring to fig. 2, another method flowchart of an alarm method in a vehicle steering process according to an embodiment of the present application is shown.
S201: the target vehicle obtains obstacle information from the road surface information.
Wherein the obstacle information includes a type, a speed, and a movement direction of the obstacle. Alternatively, the target vehicle may obtain a plurality of pieces of obstacle information at the same time, the obstacle information referring to information such as movement information and attribute information of obstacles around the target vehicle. Of course, the obstacle information may also include other information, such as the current position information and a plurality of historical positions of the obstacle, and the like, which also does not affect the normal implementation of the embodiments of the present application.
S202: and the target vehicle obtains an estimated obstacle track according to the obstacle information.
The target vehicle can predict the track of the obstacle in a period of time in the future according to the obstacle information, and whether the obstacle collides with the target vehicle is estimated according to whether the estimated track of the obstacle and the estimated track of the vehicle have intersection points.
S203: and the target vehicle obtains a vehicle estimated track according to the vehicle motion information.
The vehicle motion information of the target vehicle may include: steering of a steering lamp, speed of a target vehicle, current running direction of the target vehicle, current position and length of a vehicle body, and the like. In order to avoid time delay, the current position may be represented by a plurality of historical coordinate values within 5 seconds.
Alternatively, to save computational resources and buffer resources, the estimated obstacle trajectory and the estimated vehicle trajectory may be calculated only for a certain period of time, e.g., the estimated obstacle trajectory and the estimated vehicle trajectory may be required to occur within 10 seconds.
S204: and the target vehicle obtains alarm information according to the estimated track of the obstacle and the estimated track of the vehicle.
Alternatively, the target vehicle may obtain the warning information by: first, the target vehicle obtains estimated collision point information according to obstacle information and estimated vehicle tracks. And obtaining corresponding collision information according to the estimated collision point information, and finally generating alarm information according to the estimated collision point information and the corresponding collision information. For example, the information of the estimated collision point may be a time point and a position point of the estimated collision within 10 seconds in the future, and the corresponding collision information may be a distance between the position of the estimated collision and the current position of the vehicle and a duration between the time of the estimated collision and the current time. In some possible implementations, if the distance between the estimated collision position and the current position of the vehicle exceeds 20 meters, setting the alarm level in the alarm information as a common alarm; if the distance between the estimated collision position and the current position of the vehicle is less than 15 meters, but the duration between the estimated collision time and the current time exceeds 5 seconds, setting the alarm level as a dangerous reminder; if the distance between the estimated collision position and the current position of the vehicle is smaller than 10 meters and the duration between the estimated collision time and the current time is smaller than 5 seconds, setting the alarm level as collision reminding. Optionally, the target vehicle may obtain a plurality of estimated collision point information, and when the alarm levels obtained by the estimated collision point information are different, alarm information with the smallest duration between the estimated collision time and the current time is preferentially alarmed.
S205: and the target vehicle alarms according to the obtained alarm information.
In some possible implementations, the target vehicle displays the warning information on the front windshield of the vehicle through the screen projection device, and the warning information may be specifically displayed in the following manner: first, the type of the obstacle, the current position of the obstacle and the alarm level are read according to the alarm information. Corresponding icons, which may be objects, people, non-motor vehicles, etc., are then displayed according to the type of obstacle. And finally, displaying the current position of the obstacle by using the dangerous object distance scale, and displaying different alarm levels by using different colors, such as displaying a common alarm in green, displaying a dangerous alarm in yellow and displaying a collision alarm in red. Of course, whether the sound reminding needs to be triggered or not can also be judged through the alarm level in the alarm information, and the normal implementation of the embodiment of the application is not affected.
Alternatively, the target vehicle may exit the alert in response to turning off the turn signal. Of course, the target vehicle can exit the alarm by judging that no collision point exists in the estimated steering track of the target vehicle.
According to the method and the device, the road information provided by the road side cooperative unit is utilized to generate the alarm information, so that the detection blind area is greatly reduced, the high-resolution detection radar with high price is not required to be installed, the detailed road information can be provided for the vehicle more comprehensively and accurately, the production cost of the vehicle is reduced, and meanwhile, the safety coefficient of the vehicle in steering is improved.
