Embodiment Construction

[0055] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0056] Such as Figure 1-3 As shown, the method for determining the width of the straight line section of the dedicated lane for automatic driving vehicles of the present invention includes the following steps:

[0057] S1. Install the vehicle-mounted ranging device 1 in the center of the front of the vehicle, and calibrate the measurement accuracy of the device, as follows:

[0058] S101. Install the equipment in the center of the front of the car, which can be confirmed with a steel ruler with millimeter-level precision, so that the installation error of the equipment should be less than 0.5cm;

[0059]S102. Calibrate the measurement accuracy of the equipment, and automatically calculate the error of the distance x f...

Abstract

The invention relates to a method for determining the width of a straight-line segment of a special lane for an automatic driving vehicle, and the method comprises the steps of S1 a vehicle-mounted distance measurement device is installed at the center of the front part of the vehicle, and the measurement precision of the device is calibrated; S2 the automatic driving vehicle runs in the lane, and the transverse swing amplitude of the vehicle is measured; S3 a statistical method is used to obtain a function relationship between the transverse swing amplitude of the automatic driving vehicle in the lane and the influence factors; S4 the probability that the edge line of the vehicle is enveloped by the lane line is taken as the transverse movement reliability of the vehicle, and lane widths with different transverse movement reliability are obtained through reverse deduction; S5 free flow speed and traffic capacity conditions of automatic driving vehicles with different widths are checked; and S6 the width of the straight-line section of the special lane for the automatic driving vehicle on a highway is determined. According to the method, seven influence factors of transverse swinging of the automatic driving vehicle in the lane are considered, and the width of the straight-line section of the lane special for the automatic driving vehicle on the highway can be determined more scientifically.

Description

technical field [0001] The invention relates to the technical field of traffic design, in particular to a method for determining the width of a straight line section of a special lane for an automatic driving vehicle. Background technique [0002] Capacity is one of the core concepts of traffic engineering, and it is also the theoretical cornerstone of traffic planning, traffic design, traffic management and control. As autonomous vehicles are mixed into the traffic flow of human driving vehicles (HDV), especially autonomous vehicles can be divided into single-vehicle intelligent autonomous vehicles (Autonomous Vehicle, AV) and intelligent network-linked autonomous vehicles (Connected Autonomous Vehicles). ,CAV), the existing capacity algorithm has shown its incompatibility. Since the expressway is a free flow, the traffic environment is relatively simple compared with urban roads, so the current promotion of autonomous vehicles often starts from the expressway. Therefore,...
