Embodiment 1

[0033] Such as figure 1 As shown, the flow of the method for assisting the vehicle to safely change lanes in this embodiment is as follows:

[0034] Step 101: Collect pictures of traffic lanes on the road through the camera on the vehicle.

[0035] Step 102: Judging whether the traffic line on the road surface is a dotted line through the collected pictures, if it is a dotted line, proceed to step 103, if it is not a dotted line, then proceed to step 106.

[0036] Step 103: Use radar to detect whether there is a target vehicle within a certain distance from the vehicle on the target lane, if yes, proceed to step 104, if not, proceed to step 107. The range of radar monitoring can be set to a fixed 40m, or can be set according to the user

[0037] Step 104: Determine the distance between the target vehicle and the own vehicle, and calculate the speed of the target vehicle.

[0038] Step 105: Make a logical judgment based on the distance between vehicles and the speed of the r...

Embodiment 2

[0047] Such as figure 2 As shown, the flow of the method for assisting the vehicle to safely change lanes in this embodiment is as follows:

[0048] Step 201: Collect pictures of traffic lanes on the road through the camera on the vehicle.

[0049] Step 202: Judging whether the traffic line on the road surface is a dotted line through the collected pictures, if it is a dotted line, proceed to step 203, if not, proceed to step 206.

[0050] Step 203: Use radar to detect whether there is a target vehicle within a certain distance from the vehicle on the target lane, if yes, proceed to step 204, if not, proceed to step 207. The range of radar monitoring can be set to a fixed 40m, or can be set according to the user

[0051] Step 204: Determine the distance between the target vehicle and the own vehicle, and calculate the speed of the target vehicle.

[0052] Step 205: Make a logical judgment based on the distance between vehicles and the speed of the rear vehicle. When the di...

Embodiment 3

[0066] Such as image 3 As shown, the vehicle includes a power battery 1, and the system for assisting the vehicle in safely changing lanes includes a camera 2, a controller 3, a radar 4, a left / right lane change switch 5, a start switch 6 and an alarm device, and the power battery 1 supplies power to the system , the radar 4 is arranged on the rear bumper of the vehicle, the left / right lane change switch 5 is arranged on the steering wheel, the camera 2, the radar 4, the left / right lane change switch 5 and the start switch 6 are all connected to the input interface of the controller 3 , the output interface of the controller 3 is connected to an alarm device.

[0067] Specifically, the camera 2 is arranged at the bottom of the exterior rearview mirrors on both sides of the vehicle, the height of the camera 2 relative to the road surface is H, and the angle between the optical axis of the camera 2 and the driving direction of the vehicle is 90°, and the optical axis of the cam...

Abstract

The invention provides a method and a system for safe lane change of an auxiliary vehicle and belongs to the technical field of automobiles. The invention solves the problems in the prior art that a vehicle lane change reminder system is low in intelligent degree, and problems can not be completely considered. The method comprises the following steps: step 1, determining whether a road mark on a pavement on one side of a target lane allows the change of a lane or not, wherein the step 2 is carried out if the lane is allowed to be changed, and a prompt for showing that the lane is not allowed to be changed is output if the lane is not allowed to be changed; and step 2, determining whether a target vehicle exists within a certain distance from the target lane to the vehicle, wherein a prompt for showing that the lane is allowed to be changed is output if no target vehicle exists, and if the target vehicle exits, whether the lane is allowed to be changed or not is determined, and a corresponding prompt is output. The system comprises a camera, a controller, a radar, a left-right lane change switch, a starting switch and an alarm device and is used for realizing the method. According to the adoption of the scheme, the method and the system have the beneficial effects that a driver can be effectively helped to judge the lane, and the occurrence rate of accidents is reduced.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and relates to a method and system for assisting vehicles in changing lanes safely. Background technique [0002] Traffic problems in modern society are becoming more and more serious, people's driving conditions are becoming more and more complicated, and there are more and more vehicles on the road. In pursuit of speed and time, it is inevitable for drivers to frequently change lanes when driving on the road. On the one hand, the behavior of changing lanes in a hurry and not obeying the traffic rules will often cause considerable traffic safety hazards; on the other hand, changing lanes is not easy for drivers to master the technology of changing lanes, especially for novice drivers. , They have no idea about changing lanes. They often try to change lanes on the road based on their feelings. The timing, angle and speed of changing lanes can cause traffic accidents such as rear-end c...
