Embodiment Construction

[0035] The present invention will be further explained below in conjunction with the accompanying drawings.

[0036] like figure 1 As shown, the present invention is a road geometry design method for automatic driving, which mainly includes the following steps:

[0037] (1) Combining vehicle vision, control decision-making system and driving environment monitoring system to analyze the main differences of L1-L5 vehicles in terms of road geometric alignment indicators, and obtain key difference parameters;

[0038] According to SAE (Society of Automotive Engineers) Standard J3016’s grading standards for vehicles in 2014, the current vehicle is based on: vehicle (steering wheel steering and acceleration and deceleration) control, driving environment monitoring, dynamic driving task support and system scope in driving mode. The main undertakers (human driver or vehicle computer system) are divided into six levels (L0~L5):

[0039] L0 level vehicle: no automation vehicle (in pha...

Abstract

The invention discloses a road geometric alignment design method facing toward automatic driving. The road geometric alignment design method facing toward automatic driving comprises the steps of combining a vehicle vision and control decision system and a driving environment monitoring system to analyze main differences, related to road geometric alignment design elements, of vehicles L1 to L5; obtaining a key difference parameter; calibrating the key difference parameter; calculating road geometric alignment index design values of the vehicles L1 to L5; judging the degrees of influences of vehicle automatic grades on the related road geometric alignment indexes; and according to the obtained road geometric alignment index design values of the vehicles L1 to L5, designing the road geometric alignment indexes facing toward the vehicles with different automatic grades. According to the road geometric alignment design method facing toward automatic driving, a shortcoming that an existingroad geometric alignment design is lack of considering to use the vehicles with the different automatic grades as design vehicle models is solved.

Description

technical field [0001] The invention belongs to the technical field of road geometric alignment design, and relates to a road geometric alignment design method for automatic driving. Background technique [0002] The introduction of autonomous vehicles into the road traffic environment has been verified to have the possibility of improving traffic safety, road capacity, driving speed, driving efficiency, and reducing energy consumption and greenhouse gas emissions. With the gradual maturity of autonomous driving technology, Beijing, Shanghai, Fuzhou and other places in China have begun to open road tests for autonomous driving vehicles (open road sections or designated test road sections), and issued autonomous driving road test licenses. It is foreseeable that with the further development of autonomous driving technology, the penetration rate of vehicles with different automation levels in the road traffic environment will gradually increase. [0003] Roads are an importan...
