Abstract

The invention provides a vehicle lane changing control method and device and a vehicle, and the method comprises the steps of determining a predicted target lane line of the vehicle based on a lane changing direction in a lane changing instruction, a current lane line detected by the vehicle, and a lane width if a lane changing control condition is satisfied; determining a first expected direction turning angle of the vehicle based on the predicted target lane line, and controlling the vehicle to steer based on the first expected direction turning angle until the vehicle detects the target lane line; and based on the target lane line, determining a second expected direction turning angle of the vehicle, and based on the second expected direction turning angle, controlling the vehicle to enter a lane determined by the target lane line for driving. According to the method, the device and the vehicle provided by the invention, a high-precision map and high-precision positioning are not needed, so that the calculated amount of a lane changing control algorithm of the vehicle is small, the lane changing process can be stably realized, and the control effect of lane changing control is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical engineering, in particular to a vehicle lane change control method, device and vehicle. Background technique [0002] With the continuous acceleration of the research and development, application and commercialization of assisted driving technology, more and more vehicles have begun to install and run assisted driving systems. The conventional assisted driving system can only automatically drive the vehicle in one lane. In the case of congestion ahead or lane misalignment, the assisted driving system cannot control the vehicle to avoid obstacles and change lanes. At this time, the assisted driving system needs to control the vehicle to change lanes according to the driver's lane change command. [0003] Existing vehicle lane change control methods are usually based on high-precision maps and positioning and navigation information provided by high-precision positioning information, which are fu...
