Method for testing road capacity of vehicle in closed scene

Abstract

The invention discloses a method for testing the road capacity of a vehicle in a closed scene. A processor, an attitude and position acquisition module, a laser radar and a laser ranging sensor are installed on a vehicle, a rectangular marker and a plurality of target points are arranged in a closed test site, and the processor completes construction of a current environment map through the laserradar by adopting a known algorithm; and the vehicle is placed on one target point, the number of test turns or the test time is set, testing is started through automatic driving, the processor receives data fed back by the attitude and position acquisition module, the laser radar and the laser ranging sensor in real time, analyzes the data in combination with the constructed environment map, determines an optimal speed evaluation index, and then controls the vehicle to run at the optimal linear speed and angular speed according to the determined optimal speed evaluation index. Vehicle road capacity testing is carried out through automatic driving instead of manual driving, so that the vehicle can be uninterruptedly and safely tested, and the labor intensity of personnel is effectively reduced.

Description

technical field [0001] The invention relates to a vehicle road capability test method in a closed scene, belonging to the technical field of automatic driving. Background technique [0002] For vehicles such as special vehicles, passenger cars, and cars, a large number of vehicle road capability tests are required during the research and development process to verify the vehicle’s fatigue durability, vehicle strength, braking performance, fuel economy, etc. These tests The content currently mainly relies on the driver to drive the vehicle to test in a closed scene. In a closed road scene, the driver is prone to visual fatigue, and driving for a long time will also easily cause the driver's fatigue, and it is impossible to conduct a long-term test. For hot or cold And other extreme weather will also have an impact on the driver. [0003] In the test in a closed scene, there are very few interference factors such as pedestrians and other vehicles. Therefore, how to replace ma...
