step 101: in the process of driving of the first vehicle, a first driving parameter of the first vehicle is acquired.
The embodiment of the application can be applied to a scene that the vehicle environment sensing equipment is utilized to obtain the running parameters of the vehicle and the target object which are positioned in different directions of the first vehicle so as to assist in judging whether the vehicle and the target object collide.
The first vehicle refers to a vehicle equipped with a vehicle environment sensing device, and the environment sensing device in the first vehicle can be used for sensing the surrounding environment of the first vehicle, such as acquiring information of the position, speed and the like of the vehicle located in the preset distance range of the first vehicle.
In this example, the vehicle environment sensing device may be an ADAS (Advanced Driver Assistance System), which uses various sensors (millimeter wave radar, laser radar, single/binocular camera, and satellite navigation) installed on the vehicle to sense the surrounding environment at any time during the driving of the vehicle, collect data, perform identification, detection, and tracking of static and dynamic objects, and perform systematic operation and analysis in combination with navigation map data, thereby allowing the Driver to detect the possible danger in advance, and effectively increasing the comfort and safety of the driving of the vehicle.
The first driving parameter refers to a driving parameter of the first vehicle, and in this example, the first driving parameter may include a driving speed, a driving direction, a current driving position, and the like of the first vehicle.
During the driving of the first vehicle, the first driving parameters of the first vehicle can be acquired in real time. In a specific implementation, during the running process of the first vehicle, the vehicle-mounted terminal of the first vehicle may record the running parameters (such as speed, position, running direction, etc.) of the vehicle in real time.
After the first driving variable of the first vehicle is acquired, step 102 is executed.
Step 102: and acquiring a second running parameter of a second vehicle positioned in the first direction of the first vehicle and a third running parameter of a target object positioned in the second direction of the first vehicle.
The first direction and the second direction refer to two different directions of the first vehicle, for example, when the first direction is to the left of the first vehicle, the second direction may be to the right or to the right of the first vehicle, etc. When the first direction is the right direction of the first vehicle, the second direction may be the left direction or the front left direction of the first vehicle, etc.
The second vehicle is a vehicle located in the first direction of the first vehicle.
The target object refers to an object located in the second direction of the first vehicle, in this example, the target object may be a movable object such as a vehicle, a pedestrian, and the like, and the specific type of the target object may be determined according to business requirements, which is not limited in this embodiment.
In the present embodiment, the target object and the second vehicle refer to two independent objects having a blind area between the target object and the driver of the second vehicle due to the blockage of the first vehicle.

After the first driving parameter of the first vehicle is acquired, a second driving parameter of a second vehicle located in the first direction of the first vehicle and a third driving parameter of the target object located in the second direction of the first vehicle may be acquired. For example, as shown in fig. 2, the vehicle in the middle of the drawing is a first vehicle, the second vehicle may be a vehicle behind the first vehicle, the target object is a motorcycle right ahead of the first vehicle, and the first vehicle may perform environment detection through the ADAS provided by the first vehicle, so that the driving parameters of the second vehicle and the motorcycle may be obtained.

In this embodiment, in order to accurately calculate whether the target object and the second vehicle will collide at a future time in the following process, the first driving parameter, the second driving parameter, and the third driving parameter are acquired at the same time, that is, the acquisition times of the first driving parameter, the second driving parameter, and the third driving parameter are the same, for example, the acquisition time of the first driving parameter is: 8/2021, 14/10: 00, then the second driving parameter and the third driving parameter are both 10 at 8 months and 14 days in 2021: 00 acquired parameters.

After the first target position, the second target position, and the third target position are obtained, it may be determined whether the first target position is the same as the second target position and/or the third target position, that is, it is determined whether the first vehicle collides with the second vehicle and/or the target object at the first time.
In another specific implementation manner of the embodiment of the application, if it is determined that the first vehicle and the second vehicle and/or the target object are located at the same position at the first future time, the deceleration prompt information or the parking prompt information may be output, and the deceleration prompt information or the parking prompt information is used for prompting a driver of the first vehicle to decelerate or park so as to avoid a traffic accident.

It can be understood that the first time and the second time may be the same time, or may be different times, and in particular, the present embodiment is not limited thereto, which may be determined according to actual situations.
When the first vehicle and the second vehicle and/or the target object are not at the same position at a first future time (that is, the first vehicle and the second vehicle and/or the target object do not collide at the first future time), it may be determined whether the second vehicle and the target object are at the same position at a second future time according to the second driving parameter and the third driving parameter, that is, it is determined whether the second vehicle and the target object collide at the second future time.

For example, as shown in fig. 2, when the following vehicle collides with the motorcycle at a future time, an alarm message may be output through the intermediate vehicle to prompt the drivers of the motorcycle and the following vehicle to take even an evasive measure. As shown in fig. 3, when a vehicle located diagonally forward of the intermediate vehicle collides with a vehicle located diagonally rearward of the intermediate vehicle at a time in the future, warning information may be output from the intermediate vehicle to prompt the motorcycle and the rear vehicle driver to take evasive measures.
