The present disclosure discloses methods and systems for testing the vehicle. In some embodiments, a method includes receiving, by an emulation server, a test task and a test scenario set required for executing the test task sent from a client; distributing, by the emulation server, each of the test scenarios to first emulation executors respectively, and sending the test task to each of the first emulation executors; acquiring, by the emulation server, a test result of the test task from each of the first emulation executors; and comparing, by the emulation server, the acquired test result with a preset test standard to generate feedback information of the test task, and sending the feedback information to the client.

Method and system for testing vehicle

The present invention discloses a vehicle control method and apparatus and a method and apparatus for acquiring a decision-making model. The vehicle control method, comprising: during travel of an unmanned vehicle, acquiring current external environment information and map information in real time; determining vehicle state information corresponding to the external environment information and map information acquired each time according to a decision-making model obtained by pre-training and reflecting correspondence relationship between the external environment information, map information and vehicle state information, and controlling a travel state of the unmanned vehicle according to the determined vehicle state information. Application of the solution of the present invention can improve security and reduce the workload.

Vehicle control method and apparatus and method and apparatus for acquiring decision-making model

The present invention discloses a method and apparatus of obtaining feature information of a simulated agent. The method further comprises: for each agent class, respectively obtaining feature information of real agents belonging to the class and freely participating in traffic activities, the number of real agents belonging to each class being greater than one; for each agent class, extracting representative feature information from feature information of each real agent belonging to the class, and taking the extracted feature information as feature information of simulated agents belonging to this class. The solution of the present invention may be applied to improve correctness of testing results of unmanned vehicles.
