The present disclosure discloses a method and system for constructing a predictive vehicle driving condition, a device and a medium. The method includes: acquiring a first road set and historical vehicle driving data; screening distances less than or equal to a distance threshold from the first distance set, generating a road point-in-time set; sequencing a plurality of point-in-time corresponding to the same road segment, and cutting at two adjacent point-in-time with a time difference greater than a time threshold, to obtain a plurality of road segments; establishing road segment databases; screening segments with segment feature data meeting a second preset condition from all the road segment databases, and generating a road-condition segment set; and sequencing a plurality of condition segments corresponding to each road segment, and screening condition segments meeting a third preset condition from all the segment sequences, to generate an optimal driving condition.

A method, a system and a device for determining interlaminar shear strength of a composite laminated plate are provided. The method includes following steps: constructing a force-displacement curve of a composite laminated plate specimen based on strain data, corresponding to different displacements of the indenter, of the composite laminated plate specimen; determining a dominant strain based on plane strain nephograms; reading any defect in the plane strain nephogram corresponding to one displacement as a current defect, and determining a test force acting on the whole composite laminated plate specimen corresponding to the reference displacement of the indenter as a critical strain value; determining a product of the critical strain value and shear modulus under the dominant strain as the shear strength between adjacent single layers to be tested.

Disclosed are a test routes planning method and apparatus of a vehicle on actual roads, a medium and a device. The method includes the following steps: dividing road traffic scenes; calculating traffic scene characteristics based on the divided road traffic scenes; constructing a preliminary road selection database for test routes; and completing a planning of the test routes of the vehicle on the actual roads at different speeds in different traffic scenes by leveraging a genetic algorithm based on the preliminary road selection database for the test routes. The present disclosure provides a solution for planning the test routes of the vehicle on the actual roads. In the solution, the travel speed distribution of a user is obtained through calculation based on traffic flow big data, and the planning of the test routes on the actual roads in different traffic scenes is completed by leveraging the genetic algorithm.
