| description | The invention relates to an unmanned vehicle drive-by-wire performance detection method and device, electronic equipment and a storage medium. The method comprises the steps that the size of a test site is calculated and generated based on basic parameter information of a preset vehicle; generating a path point pose based on the test path, assigning a value to the path point based on a given test accelerator, and generating a task file; performing trajectory tracking control on the to-be-tested unmanned vehicle based on a preset transverse and longitudinal control algorithm, and recording front wheel turning angle and accelerator/brake feedback information; and respectively calculating adjustment time, overshoot and steady-state error, respectively evaluating rapidity, stability and precision, and weighting according to preset coefficients of different vehicle types to complete detection and evaluation of the drive-by-wire performance of the to-be-tested unmanned vehicle. According to the invention, a plurali |
