Embodiment 1

[0038] A kind of smart car of the present embodiment follows the test and evaluation method autonomously around the pile, comprising the following steps:

[0039] Such as figure 1 As shown in S1, determine the start point and end point, and arrange several test piles between the start point and end point. times, 2.5 times and 3 times the test pile spacing, the order of the test pile spacing is adjusted randomly; the maximum distance between the farthest two test piles among the three adjacent test piles should not be less than 0.5 times the vehicle length, and the maximum distance should be At least 2 meters longer than the length of the car. The maximum outer diameter of the test pile is not greater than 0.06m, and the height is greater than or equal to 1.5m.

[0040] The distance from the starting point to the first test pile is 3 times the width of the vehicle. The traffic width at the starting point is 3 times the width of the vehicle, and should be at least 2 meters wi...

Embodiment 2

[0074] The difference between this embodiment and Embodiment 1 is that in S503 of this embodiment, there are multiple cameras, and at least one camera is controlled to capture real-time images of the road surface after the vehicle under test travels, and at least one camera is also controlled to capture real-time images of the detected vehicle. Measure the image of vehicle running; In the present embodiment, camera is greater than 3.

[0075] It also includes S505. The server judges whether the running track of the tested vehicle is smooth, and if not, judges whether the running track of the tested vehicle is smooth based on the running image of the tested vehicle; if it is not smooth, no processing is performed; if it is smooth, skip to S506;

[0076] S506. Control at least one camera to capture the footprint image of the guide and the walking image of the guide, and judge whether the guide walks smoothly based on the walking image of the guide. If it is smooth, then judge whe...

Abstract

The invention relates to the technical field of vehicle testing, and particularly discloses an intelligent vehicle pile-surrounding autonomous following test evaluation method, which comprises the following steps of: S1, determining a starting point and an ending point, and arranging a plurality of test piles between the starting point and the ending point; S2, setting a path sequence for a guider to start from the starting point and travel around the piles to the ending point; S3, starting timing when the guider starts from the starting point; S4, when the guider departs, inputting a following instruction to a tested vehicle, and enabling the tested vehicle to follow the guider to advance; S5, recording the driving track of the tested vehicle; S6, when the foremost end of the tested vehicle in the advancing direction passes through the ending point, stopping timing, and ending pile surrounding; and S7, based on the driving track of the tested vehicle, calculating the evaluation score of the tested vehicle according to a preset scoring rule. By adopting the technical scheme of the invention, the autonomous following capability can be accurately tested.

Description

technical field [0001] The invention relates to the technical field of vehicle testing, in particular to an evaluation method for an intelligent vehicle autonomously following a pile around a pile. Background technique [0002] In "GB / T26773-2011 Intelligent Transportation System Lane Departure Warning System Performance Requirements and Testing Methods", the definition, classification, function, human-machine interface (HMI) and detection method, etc. However, the above method is only applicable to the situation of standardized lane markings, and is not suitable for road sections with temporary and irregular lane markings (such as road construction areas). [0003] The current standards such as "Adaptive Cruise Control System Test Procedure i-VISTA+SM-ADAS-ACCT-A0-2018" and "Adaptive Cruise Control System Evaluation Procedure i-VISTA+SM-ADAS-ACCR-A0-2018" The paper mainly examines the lane departure control ability, straight-line following ability and lane-change followin...
