Embodiment Construction

[0031] The present invention is further described below in conjunction with the accompanying drawings:

[0032] see figure 1 , the method for generating an intelligent driving test route provided by this embodiment includes the following steps:

[0033] 1. Define the road static scene complexity model and its calculation method

[0034] The road static scene complexity model defined in this step includes 17 core scene elements, see Table 1.

[0035] 1.1. Calculate the complexity Ci of a single scene element.

[0036] 1.1.1. For Boolean value type elements (such as tunnels), the complexity Ci is 1 when it appears in the scene, otherwise it is 0.

[0037] 1.1.2. For elements of non-Boolean value types (such as slope and curvature), normalize them according to the following formula to obtain their own complexity.

[0038] slope:

[0039]

[0040] where:

[0041] gra represents the average gradient of the road meeting the target value, and the target value gra ≥ 3%;

[0...

Abstract

The invention relates to an intelligent driving test route generation method, which comprises the following steps of: defining road static scene complexity and a calculation method thereof, constructing a road scene complexity model, filtering out road sections with high scene complexity, and connecting the road sections through a map tool to obtain a continuous high scene complexity test route. According to the route screened by the method, the scene complexity in unit mileage is high, the difficulty of perception and fusion of the driving assistance system can be increased by selecting the route, the system operation load is improved, and the purpose of improving the test efficiency is achieved.

Description

technical field [0001] The invention relates to the field of intelligent driving test, and is specifically applied to road selection for intelligent driving test of the whole vehicle. Background technique [0002] At present, the intelligent driving assistance system is becoming more and more mature, and the number of cars with driving assistance functions is increasing year by year. The intelligent driving assistance system uses its rich on-board sensors to realize the lateral and vertical control of the vehicle through the perception of the traffic environment. Using the intelligent driving assistance function will help reduce the driver's fatigue caused by long-distance driving and improve driving comfort. [0003] In the model development stage, the vehicle road test of the intelligent driving assistance system is an indispensable part of the development process. However, the MIL, SIL, and HIL tests in the development stage are limited by the test platform, and the per...
