Method and device for adjusting vehicle attitude

Abstract

The invention discloses a method and a device for adjusting vehicle attitude, and relates to the technical field of computers. One specific implementation mode of the method comprises the steps: determining a first target point closest to a vehicle on a stop line under the condition that the attitude of the vehicle needs to be adjusted, calculating the distance from the first target point to an intersection point, and obtaining the adjustable width of a vehicle attitude adjustable area in combination with a preset width; determining the orientation of the intersection point on the guide line, translating the first target point to the vehicle for a preset distance along the opposite direction of the orientation to obtain a second target point, and taking the second target point as an initial center point of the vehicle attitude adjustable area; and taking the initial center point as a center, constructing the vehicle attitude adjustable area based on the adjustable width and the preset length so as to adjust the attitude of the vehicle. According to the embodiment, path planning is carried out by calculating the appropriate parking point coordinates and orientation so that the traffic light is located in the view of the vehicle sensor, and the vehicle attitude is rapidly and effectively adjusted.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and a device for adjusting vehicle posture. Background technique [0002] When a high-speed self-driving vehicle is driving in a motorway, it can easily turn left, go straight, and take corresponding measures when it sees a traffic light signal. However, low-speed self-driving vehicles generally drive on non-motorized lanes. Turning left generally requires two crosswalks, which is equivalent to two straight trips, and two traffic lights need to be checked. see figure 1 As shown, it is a left-turning scene of a low-speed automatic driving vehicle. When driving from lane1 to lane2, the status of traffic light signal1 is required, and when driving from lane2 to lane3, the status of traffic light signal2 is required. [0003] In the process of realizing the present invention, the inventors have found that the existing low-speed automatic driving vehicles have at least th...

Problems solved by technology

[0004] In view of this, the embodiment of the present invention provides a method and device for adjusting the attitude of the vehicle, which can at least solve the problem of unadjusted vehicle attitude when the existing low-speed automatic driving vehicle turns. The phenomenon that the traffic lights cannot be within the field of view of the sensor and affect the driving of the vehicle
