Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0033] figure 1 Shown is an embodiment of the curved road design method based on the excellent driver's driving trajectory in the present invention. to determine the shape of the curved road surface, such as figure 1 As shown, the specific implementation steps are:

[0034] Step 1: Driver selection, select excellent drivers as the experimental subjects.

[0035] Taking into account factors such as gender, age, and driving experience, the actual vehicle test personnel are five drivers from the driving school. Gender factor, based on the principle of a male to female ratio of 4:1, select four male coaches and one female coach; age factor, considering the driving differences of drivers of different ages, the age span of the coaches is 28 to 55 years old; In ter...

Abstract

The invention provides a curve colored pavement design method based on excellent driver driving trajectories. The method determines the shape of a curved colored pavement according to the driving trajectory law of excellent drivers at the curve. The method includes: selecting excellent drivers as the experiment objects; designing and implementing a driver curve experiment to collect the driving trajectory data of the excellent drivers at the curve to obtain experiment data; analyzing the experiment data to obtain the driving trajectory law, namely curve man-simulation trajectory reference lines, of the excellent drivers at the curve; designing the shape of the curve colored pavement according to the driving trajectory law of the excellent drivers at the curve. The method has the advantagesthat the driving trajectory features of the excellent drivers at the curve are applied to unmanned vehicles in the form of colored pavement, construction convenience is achieved while a complex routeplanning process is avoided, and man-simulated-trajectory driving of the unmanned vehicles at the curve can be achieved by directly following the boundary line of the colored antiskid pavement.

Description

technical field [0001] The invention belongs to the field of highway design, and specifically designs a method for designing curved road color road surfaces based on the driving trajectory of an excellent driver. Background technique [0002] With the development of sensor technology and computer technology, the research of unmanned vehicles has attracted more and more attention from all walks of life. In order to improve the safety and ride comfort of unmanned vehicles, the research on the driving habits and driving characteristics of human drivers has gradually become a research hotspot. Excellent drivers have the characteristics of rich driving experience, so the driving trajectory of excellent drivers has the characteristics of human-like trajectory planning in the path planning of unmanned vehicles, which makes unmanned vehicles have good human-like characteristics in subsequent path tracking . [0003] In terms of path tracking of existing driverless cars, China has ...
