Problems solved by technology

[0004] The present invention provides a control method and device for automatic lane change of a vehicle to solve the problem that the existing lane change strategy does not consider the logic control in the lane change process, and by designing the arbitration of conflicting lane change requirements during the lane change process strategy, optimize the control effect of the vehicle's automatic lane change, and promote the intelligent process of the vehicle's automatic driving

Embodiment 1

[0060] See image 3 , image 3 Shown is a schematic diagram of the vehicle changing road conditions in the first embodiment of the present invention. The vehicle (lane changing vehicle A in the figure) generates a navigation map-based lane change request that needs to be off-ramp according to the navigation destination to the right, but at this time The vehicle detects a traffic jam at the intersection, and generates a lane change request based on driving efficiency according to the driver's overtaking habit. The lane change operation corresponding to the two lane change needs conflicts. At this time, according to the preset priority, the vehicle will not turn left. Skip the line of traffic and instead wait in line until you get onto the off-ramp.

Embodiment 2

[0062] See Figure 4 , Figure 4 Shown is a schematic diagram of the vehicle changing road conditions in the second embodiment of the present invention. The vehicle (lane changing vehicle A in the figure) generates a navigation map-based lane change request that needs to be off-ramp according to the navigation destination to the right, but at this time There are many vehicles in the queue, and the driver actively intervenes to control the vehicle to the left. After the high-priority lane change to the left is completed, the vehicle will continue to execute the low-priority lane-change request, that is, according to the lane-change request based on the navigation map, Control the vehicle until you enter the off-ramp.

Embodiment 3

[0064] See Figure 5 , Figure 5 Shown is a schematic diagram of the vehicle changing road conditions in the third embodiment of the present invention. The vehicle (lane changing vehicle A in the figure) generates a navigation map-based lane change request that needs to be off-ramp according to the navigation destination to the right, but at this time There are many vehicles in the queue, and the driver actively intervenes to control the vehicle to the left. After the high-priority lane change to the left is completed, the vehicle detects a stationary obstacle M ahead. At this time, there is a lane change requirement based on safe avoidance to the left. The lane change request based on the navigation map is to the right. According to the preset priority, the vehicle will suppress the low priority left lane change request based on safe avoidance, and output the high priority right lane change request based on the navigation map. .

Abstract

The invention discloses a control method and device for automatic lane changing of a vehicle, and the method comprises the steps: obtaining a current lane changing demand of the vehicle before lane changing of the vehicle; when other different types of lane changing demands exist, determining whether to respond to the current lane changing demand or not according to the preset priority of each type of lane changing demand; and in the lane changing process of the vehicle, when conflicts with other different types of lane changing demands exist, arbitrating the conflicted lane changing demands based on the preset priority so as to correspondingly adjust the lane changing operation of the vehicle. According to the vehicle automatic lane changing control method and device provided by the embodiment of the invention, by designing the arbitration strategy of the vehicle for the conflict lane changing demand in the lane changing process, the control effect of vehicle automatic lane changing is optimized, and the intelligent process of vehicle automatic driving is promoted.

Description

technical field [0001] The invention relates to the technical field of automatic driving, and in particular, to a control method and device for automatic lane change of vehicles. Background technique [0002] The autonomous driving technology provides convenience for the driving of the vehicle, which can ensure the safety and reliability of driving and avoid fatigue driving without affecting the driving journey. [0003] In the process of automatic driving, automatic lane change plays an important role in the fast and stable driving of the vehicle. The lane change strategy of the prior art often focuses on the logic control before the vehicle changes lanes, ignoring that during the vehicle lane change process, due to different If the conflict between different lane changing requirements is not handled effectively, it will affect the control effect of the vehicle's automatic driving, which is not conducive to the user's driving experience.
