Outline
To address the problems of strong subjectivity in subjective evaluation and disconnection between objective data and subjective perception in the drivability assessment of commercial vehicles equiped with Automated Mechanical Transmissions (AMTs), a comprehensive drivability evaluation method based on the AVL-Drive test system is proposed. By designing test schemes for typical driving conditions, the AVL-Drive system is used to accurately collect multi-dimensional objective data such as vehicle speed, acceleration, and engine speed. Combined with a standardized subjective evaluation scale, a quantitative correlation model between subjective perception and objective indicators is established. The test results show that this method can realize the objective characterization of core drivability sub-items including starting smoothness and shift quality, effectively identify the drivability shortcomings of AMT commercial vehicles, provide a clear technical path for rearch and development optimization.
