And step S100, acquiring a real-time driving scene of the target vehicle when the auxiliary overtaking request is received.
In the embodiment of the application, the auxiliary overtaking request can be generated by triggering the electronic device when the driver of the target vehicle has an overtaking demand, and the real-time driving scene of the target vehicle can be acquired by a camera device or a safety auxiliary device (for example, a reverse collision avoidance radar or a parking auxiliary device) arranged on the target vehicle.
And S200, determining a required borrowing lane when the target vehicle exceeds the vehicle to be overtaken from the real-time driving scene.
In the embodiment of the application, a running vehicle positioned in front of a target vehicle can be determined from a real-time running scene and is used as a vehicle to be overtaken.
In addition, in this embodiment of the application, before step S200 is executed, an origin lane corresponding to the target vehicle (that is, a lane where the target vehicle is located before the vehicle to be overtaken on the borrowing lane) may be determined from the real-time driving scene, and lane attributes of the origin lane may be obtained, where, taking a bidirectional four-lane highway as an example, the highway is divided into a left overtaking lane, a middle position lane and a right emergency lane, and then the lane attributes of the origin lane may be a overtaking lane, a travelling lane or an emergency lane.
Based on the above description, in the embodiment of the application, after the original lane corresponding to the target vehicle is determined from the real-time driving scene and the lane attribute of the original lane is obtained, the borrowing lane required by the target vehicle when the target vehicle surpasses the vehicle to be overtaken can be determined from the real-time driving scene according to the lane attribute of the original lane. For example, if the lane attribute of the origin lane is the passing lane, the lane to be borrowed, which is required when the target vehicle passes the vehicle to be passed, may be determined from the real-time driving scene, and if the lane attribute of the origin lane is the passing lane, the lane to be borrowed, which is required when the target vehicle passes the vehicle to be passed, may be determined from the real-time driving scene as the passing lane.
In step S300, an auxiliary passing strategy is generated based on the position and direction of the borrowed lane with respect to the target vehicle.
In order to further ensure safe and effective overtaking behaviors and reduce the occurrence probability of traffic accidents caused by the overtaking behaviors, in the embodiment of the present application, before executing step S300, it is further required to determine whether the lane occupation state of the borrowed lane meets the first preset overtaking requirement. Based on this, the method for assisting in passing car provided in the embodiment of the present application may further include step S011, step S012, and step S013 before step S300 is executed.

In the embodiment of the present application, the first preset overtaking request may be: the method comprises the steps that no other running vehicle exists in a first preset distance range in front of a target vehicle on a borrowing lane, no other running vehicle exists in a second preset distance range behind the target vehicle on the borrowing lane, meanwhile, the borrowing lane is not shielded, and in actual implementation, the first preset distance range and the second preset distance range can be determined according to the speed limit size of the borrowing lane, and the method is not specifically limited.
Similarly, in order to further ensure a safe and effective overtaking behavior and reduce the occurrence probability of a traffic accident caused by the overtaking behavior, in the embodiment of the present application, before step S300 is executed, it is further required to determine whether the driving state of the vehicle to be overtaken meets a second preset overtaking requirement, and based on this, the method for assisting in overtaking provided by the embodiment of the present application may further include step S021, step S022, step S023 and step S024 before step S300 is executed.
And S021, acquiring the running state of the vehicle to be overtaken.

In the embodiment of the present application, if the lane attribute of the origin lane corresponding to the target vehicle is a lane, the lane attribute of the lane is a passing lane, that is, the actual passing demand is: and (3) overtaking in the overtaking lane, wherein the corresponding second preset overtaking requirement is as follows: the method comprises the following steps that a vehicle to be overtaken runs on an original lane (namely, a traffic lane) in a standard and stable mode, the running speed is within a speed limit range specified by the traffic lane, if the lane attribute of the original lane corresponding to a target vehicle is the overtaking lane, the lane attribute of the borrowing lane is the traffic lane, namely, the actual overtaking requirement is as follows: and if the vehicle overtakes on the traffic lane, the corresponding second preset overtaking requirement is as follows: the vehicle to be overtaken normally and stably runs on the original lane (namely, the overtaking lane), and the running speed is lower than the speed limit range specified by the overtaking lane. In addition, it should be noted that, in the embodiment of the present application, whether the vehicle to be overtaken is running regularly and stably on the origin lane, and the running speed of the vehicle to be overtaken may be obtained by analyzing the real-time driving scene related data collected by the camera device or the safety assistance device provided in the target vehicle, which are not described herein again.
In addition, for step S024, taking the lane attribute of the origin lane corresponding to the target vehicle as the traffic lane and the lane attribute of the borrowed lane as the overtaking lane, that is, the actual overtaking requirement is the overtaking of the overtaking lane, if the driving state does not meet the corresponding second preset overtaking requirement, for example, the vehicle to be overtaken does not travel on the origin lane (that is, the traffic lane) in a standard and unstable manner, the change of the separation distance between the target vehicle and the vehicle to be overtaken may be monitored, and if the change of the separation distance meets the preset distance change requirement, step S300 is executed to generate the auxiliary overtaking strategy based on the position direction of the overtaking lane relative to the target vehicle.

And step S340, generating an auxiliary overtaking strategy by combining the position direction and the safe distance of the borrowing lane relative to the target vehicle.
In the embodiment of the application, the vehicle type information of the vehicle to be overtaken can be acquired by analyzing the real-time driving scene related data acquired by the camera device or the safety auxiliary device arranged on the target vehicle, for example, analyzing the vehicle image information in the real-time driving scene. In addition, in the embodiment of the present application, the medium and small-sized vehicles may include a medium passenger car, a small passenger car, and a mini passenger car, and the large-sized vehicle may include a large passenger car, a freight car, and a tank car.
