Embodiment 1

[0078] For the AEB(FCW)-CCRm scenario, set the test vehicle speed V to be 75km / h, and the acceleration a to be 2m / s 2 , k 1 Take 1.2, k 2 Take 1.5, the length of the reserved segment is L 5 Take 100m, calculate

Embodiment 2

[0080] For the ACC-target vehicle cut-in scenario, set the test vehicle speed V to be 150km / h, and the acceleration a to be 2m / s 2 , k 1 Take 1.0, k 2 Take 2.0, the length of the reserved segment is L 5 Take 200m, calculate

Embodiment 3

[0082] For a long tunnel scene, set the test vehicle speed V to be 100km / h, and the acceleration a to be 2m / s 2 , k 1 Take 0, k 2 Take 1.5, the length of the reserved segment is L 5 Take 100m, calculate

[0083] The invention provides a method for estimating the road length demand of the intelligent network connection test site, which comprehensively considers the current L2 level various standards, 14 items of the three ministries and commissions regulations, group standards, intelligent network connection function decomposition, test site benchmarking, faults Use cases and typical roads in China can effectively guide the formulation of vehicle test plans and avoid the problem that the roads on the site do not meet the test requirements.

Abstract

The invention relates to a method for estimating the road length requirement of an intelligent connected automobile test field. The method comprises the following steps: dividing the road length of the intelligent connected test field into a starting acceleration section, a stable speed preparation section, a test section, a deceleration brake section and a safety reservation section; setting uniform acceleration running of a whole vehicle at the starting acceleration section, uniform running of the whole vehicle at the stable speed preparation section, uniform running of the whole vehicle atthe test section and uniform deceleration running of the whole vehicle at the deceleration brake section; estimating the length of each section; and estimating the total length of the intelligent connected test field road. The method can completely support the estimation of the lengths of various testing roads in the intelligent connected test field, and can effectively solve a problem that the lengths of roads built in the intelligent connected test field are fuzzy.

Description

technical field [0001] The invention belongs to the technical field of intelligent networked vehicles, and relates to a method for estimating the road length demand of an intelligent networked vehicle test site. Background technique [0002] In recent years, ICVs have developed rapidly. Domestic ICVs will reach L3 and L4 levels in 2020, and L5 levels will be achieved in 2025. In order to ensure the safe operation of ICVs on the road, they need to be verified in a closed test field. [0003] The construction of intelligent networked vehicle proving grounds and testing standard systems at home and abroad has just started and is not yet mature. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a method for estimating the road length demand of the intelligent networked vehicle test site, which can effectively support the construction of the road length of the intelligent networked test site, and can effectively avoid t...
