Simulation test method and device

Abstract

The invention discloses a simulation test method and device. The method comprises the steps that a simulation platform can obtain a preset electronic map, builds a simulation environment corresponding to the electronic map, and then can build a to-be-tested simulation vehicle in the simulation environment; and according to the preset traffic flow density and the state data of the simulation vehicle in the simulation environment, simulation obstacles located in the set range of the simulation vehicle are constructed in the simulation environment, and the number of the simulation obstacles located in the set range of the simulation vehicle is in positive correlation with the traffic flow density. The simulation platform can carry out simulation test on the simulation vehicle in the simulation environment according to the constructed simulation obstacles located in the set range of the simulation vehicle, and compared with the prior art, the method has improved simulation test efficiency.

Description

technical field [0001] This specification relates to the field of unmanned driving, in particular to a method and device for simulation testing. Background technique [0002] In the field of unmanned driving, in order to apply unmanned vehicles in real life, it is often necessary to develop a variety of control algorithms for unmanned vehicles. The control algorithm (referred to as unmanned driving algorithm) is initially tested to verify the control algorithm. [0003] In the prior art, it is possible to add simulated roads, traffic lights on the roads, traffic signs on the roads, obstacle vehicles and pedestrians, etc. by manual editing in the preset simulation environment, and preset these simulation models trajectories, so that these simulation models travel in the simulation environment according to the preset movement trajectories, so as to simulate the surrounding environment of the unmanned equipment in the simulation environment. [0004] It can be seen that in th...

Problems solved by technology

[0004] It can be seen that in the prior art, it is necessary to manually add various things simulated in the simulation environment, but in the actual simulation test, it is often necessary to simulate a variety of roads in the simulation environment, and it is also necessary to simulate many roads. Obstacle vehicles and pedestrians, etc., the existing technology is inefficient in artificially constructing a simulation environment for testing unmanned driving algorithms, which leads to low efficiency of simulation testing through the simulation environment
