[0036] The present application is further described in detail below in conjunction with the embodiments and drawings. It is to be understood that the specific embodiments described herein are only used to explain the relevant application, rather than to limit the application. It is also necessary to explain that, for ease of description, only the parts related to the application are shown in the drawings.

[0037] It should be noted that, in the absence of conflict, the embodiments of the present application, that is, the features of the embodiments, can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] The following describes in detail the vehicle assisted lane change method, system, vehicle and equipment according to the embodiments of the present application in conjunction with the accompanying drawings.

[0039] Figure 1 FIG. 1 is a flow chart of a vehicle lane change assistance method according to an embodiment of the present application. Figure 1 As shown, the vehicle lane change assistance method according to an embodiment of the present application includes the following steps:

[0040] S101: Obtain vehicle motion information on adjacent lanes within a sensing range.

[0041] Among them, the position, speed, acceleration and other information of the front and rear vehicles in the adjacent lanes can be perceived through the perception module.

[0042] S102: Estimate, based on the vehicle motion information of the own vehicle and the vehicle motion information of the adjacent lane, whether there is interference from vehicles in the adjacent lane when the own vehicle changes lanes.

[0043] In one embodiment of the present application, before estimating whether there is interference from vehicles in adjacent lanes when the vehicle changes lanes based on the vehicle motion information of the vehicle and the vehicle motion information of the adjacent lane, it also includes: based on the vehicle motion information on the adjacent lanes within the perception range, screening out the front vehicle and the rear vehicle with the smallest longitudinal distance to the vehicle from the corresponding vehicles on the adjacent lanes.

[0044] In one embodiment of the present application, based on the vehicle motion information of the own vehicle and the vehicle motion information of the adjacent lane, it is estimated whether there is interference from vehicles in the adjacent lane when the own vehicle changes lanes, including: when the distance between the front vehicle and the own vehicle is less than a predetermined distance or the distance between the rear vehicle and the own vehicle is less than the predetermined distance, it is determined that there is interference from vehicles in the adjacent lane when the own vehicle changes lanes.

[0045] In one embodiment of the present application, based on the vehicle motion information of the own vehicle and the vehicle motion information of the adjacent lane, it is estimated whether there is interference with the vehicles in the adjacent lane when the own vehicle changes lanes, and it also includes: when the distance between the front vehicle and the own vehicle is greater than a predetermined distance and the distance between the rear vehicle and the own vehicle is greater than the predetermined distance, according to the preset lane changing time of the own vehicle, the acceleration of the own vehicle, the speed of the own vehicle and the speed of the front vehicle, the speed difference between the own vehicle and the front vehicle is obtained, and according to the lane changing time of the own vehicle, the acceleration of the rear vehicle, the speed of the rear vehicle and the speed of the own vehicle, the speed difference between the own vehicle and the rear vehicle is obtained; according to the speed difference between the own vehicle and the front vehicle and the speed difference between the own vehicle and the rear vehicle, it is determined whether there is interference with the vehicles in the adjacent lane when the own vehicle changes lanes.

[0046] In one embodiment of the present application, based on the vehicle motion information of the own vehicle and the vehicle motion information of the adjacent lane, it is estimated whether there is interference from vehicles in the adjacent lane when the own vehicle changes lanes, and it also includes: when the distance between the front vehicle and the own vehicle is greater than a predetermined distance and the distance between the rear vehicle and the own vehicle is greater than the predetermined distance, based on the vehicle motion information of the own vehicle and the vehicle motion information of the adjacent lane, the distance difference when the own vehicle collides with the front vehicle and the distance difference when the own vehicle collides with the rear vehicle are estimated; based on the distance difference when the own vehicle collides with the front vehicle and the distance difference when the own vehicle collides with the rear vehicle, it is determined whether there is interference from vehicles in the adjacent lane when the own vehicle changes lanes.

[0047] Specifically, the speed of the vehicle is V, the acceleration is a, and the target vehicle ID in the lane change area is identified. Each ID has a longitudinal distance X, a longitudinal speed V, and a longitudinal acceleration a. The center of the vehicle is used as the coordinate origin. The distance to the vehicle in front of the vehicle is displayed as positive, and the distance to the vehicle behind the vehicle is displayed as negative. The ID information of the vehicle in front is the longitudinal distance Fx (m), the longitudinal speed Fv (m / s), and the longitudinal acceleration Fa (m / s 2 ), the ID information of the rear vehicle is the longitudinal distance Bx (m), longitudinal speed Bv (m / s), longitudinal acceleration Ba (m / s 2 ), only the ID of the vehicle closest to the adjacent lanes in front and behind the vehicle can be screened and identified. Then the feasibility of lane change is calculated.

[0048] 1. When there is no lateral target interference in the lane change, the lane line of the human-computer interaction is displayed in green, and you can change lanes at any time.

[0049] 2. When there is a target vehicle in the adjacent lane within 2m in front of or behind the vehicle, that is, Fx<2m||Bx<-2m, one of the two is satisfied. The target vehicle is too close to the vehicle, the human-machine interaction is displayed in red, and lane change is prohibited.

[0050] 3. Determine speed:

[0051] When Fx>2m and Bx<-2m, the following calculation is performed:

[0052] Th1=V-(Bv+Ba×t)

[0053] Th2=Fv-(V+a×t)

[0054] Where t is the lane change time of the vehicle. The normal lane change time is 2-5s. The lane change prompt setting can be selected according to the driver's driving intensity; for example, 2s is aggressive, 3s is normal, and 5s is steady. Th1 and Th2 are the speed differences between the vehicle and the rear and front vehicles, respectively.

[0055] When Th1>0, it means there is no threat behind the vehicle when changing lanes. At this time, it is judged whether there is an interfering vehicle in front of the lane changing area of ​​the vehicle. When Th2>0, it means there is no threat in front of the vehicle when changing lanes, and the lane change can be made.

[0056] If Th1<0 or Th2<0, lane changing is prohibited.

[0057] 4. Determine distance:

[0058] When Fx>2m and Bx<-2m, the following calculation is performed:

[0059]

[0060] Th3 and Th4 calculate the distance difference between the rear vehicle, the front vehicle and the vehicle when they collide.

[0061] When Th3<0, it means that there is no threat behind the vehicle when it changes lanes. At this time, it is judged whether there is an interfering vehicle in front of the lane changing area of ​​the vehicle. When Th4>0, it means that there is no threat in front of the vehicle when it changes lanes, and the lane change can be made.

[0062] If Th3>0 or Th4<0, either of them is satisfied, lane changing is prohibited.

[0063] S103: If there is interference from vehicles in adjacent lanes when the vehicle changes lanes, a lane change prohibition prompt is provided to the driver in a human-computer interaction manner; if there is no interference from vehicles in adjacent lanes when the vehicle changes lanes or there are no vehicles in adjacent lanes within the perception range, a lane change prompt is provided.

[0064] In a specific example, providing a prohibited lane change reminder to the driver in a human-computer interactive manner includes: displaying a first color on the prohibited lane change side of the vehicle icon through a head-up display or an instrument, wherein the first color is used to represent that the lane change is prohibited; when the lane is changeable, displaying a second color on the variable lane side of the vehicle icon through a head-up display or an instrument, wherein the second color is used to represent that the lane change is allowed.

[0065] like Figure 2 As shown, the area to be changed is displayed in the restored world, for example: the lane display of the lane change area is green, such as the traffic light allowing passage, that is, when the driver wants to change lanes, he can change lanes directly when he sees green, and he does not need to shake his head left and right to view the lane change environment; when the lane change is prohibited, such as the red color of the traffic light prohibiting passage, that is, when the driver wants to change lanes, he will suspend the lane change behavior when he sees red, and he does not need to shake his head left and right to view the lane change environment. It can be seen directly in the head-up display or the instrument to avoid distraction of the driver, thereby effectively improving driving safety.

[0066] According to the assisted lane changing method of the vehicle in the embodiment of the present application, by obtaining the vehicle movement information on the adjacent lanes within the perception range, it is possible to quickly and accurately estimate whether there is interference from the vehicles in the adjacent lanes when the vehicle changes lanes, and can provide the driver with a prohibited lane change prompt or a lane change prompt through human-computer interaction. Thus, it is possible to predict whether there is a risk of collision with the vehicle in the adjacent lane when the vehicle changes lanes, and display it to the driver through human-computer interaction such as a heads-up display or an instrument. The driver can intuitively see whether he can change lanes without being distracted, which can improve the lane changing efficiency to a certain extent, and can reduce the occurrence of accidents caused by driver distraction, thereby effectively improving driving safety.

[0068] An acquisition module 310 is used to obtain vehicle motion information on adjacent lanes within a sensing range;

[0069] The judgment module 320 is used to estimate whether there is interference from a vehicle in an adjacent lane when the vehicle changes lanes based on the vehicle motion information of the vehicle and the vehicle motion information of the adjacent lane;

[0070] The lane change assistance module 330 is used to provide the driver with a lane change prohibition prompt in a human-computer interaction manner when there is interference from vehicles in adjacent lanes when the vehicle changes lanes. If there is no interference from vehicles in adjacent lanes when the vehicle changes lanes or there are no vehicles in adjacent lanes within the perception range, a lane change prompt is provided.
