Problems solved by technology
That is, in practical applications, the modified trajectory planning algorithm module (the trajectory of the unmanned driving device) is simulated and tested according to the scenario test case to obtain a new planned trajectory. However, it can only be verified whether the planned trajectory meets expectations. Unable to perform simulation tests jointly with the modified control algorithm module (controlling the movement of unmanned equipment)
However, each algorithm module is independently tested by simulation, resulting in low efficiency of simulation test.

The invention discloses a simulation test method and device. Simulation test data and simulation scene data are determined, and a simulation scene and corresponding simulation equipment in the simulation scene are constructed. Then, according to the simulation test data, a planned trajectory and a simulation control quantity of the simulation equipment are determined at the (N + 1) th simulation moment, which are planned when the simulation equipment is at the Nth simulation moment in the simulation scene; finally, according to the simulation control quantity, the simulation equipment is controlled to run in the simulation scene and execute a simulation test, and according to the obtained actual simulation track of the simulation equipment at the (N + 1) th simulation moment in the simulation scene, the planned track of the simulation equipment is determined at the (N + 2) th simulation moment at the (N + 1) th simulation moment in the simulation scene. The algorithm module corresponding to the planning track and the algorithm module corresponding to the simulation control quantity can be combined for simulation testing, so that the efficiency of the simulation testing is improved.
Description
technical field [0001] This description relates to the technical field of simulation testing, in particular to a method and device for simulation testing. Background technique [0002] At present, before the road test of driverless equipment, a large number of simulation tests for optimizing different algorithm modules need to be carried out in a simulation test environment. [0003] In the prior art, scenario test cases are generated through the collected driving data, and individual simulation tests are performed on each algorithm module to verify whether the problem is solved. That is, in practical applications, the modified trajectory planning algorithm module (the trajectory of the unmanned driving device) is simulated and tested according to the scenario test case to obtain a new planned trajectory. However, it can only be verified whether the planned trajectory meets expectations. It is not possible to conduct simulation tests jointly with the modified control algori...
