Abstract

A method and device for vehicle dynamic simulation are disclosed to overcome a problem that present automatic drive vehicle simulation methods cannot efficiently simulate motion or dynamic situationsof a vehicle in different environments. The method includes: in a current calculation cycle, a vehicle dynamic simulation system receives a real-time input vehicle control command and vehicle state data of one type of vehicle; and the vehicle dynamic simulation system includes vehicle operation dynamic models of the type of vehicle running in a plurality of driving environments; the dynamic situation of the vehicle operation is simulated according to the vehicle control command, the vehicle state data and various vehicle operation dynamic models to generate simulated vehicle dynamic data; anda vehicle operation simulation system simulates the vehicle operation according to the input simulated vehicle dynamic data, generates corresponding simulated vehicle state data, and transmits the generated simulated vehicle state data to the vehicle dynamic simulation system as updated vehicle state data in the next calculation cycle.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a method and device for vehicle dynamic simulation. Background technique [0002] Autonomous vehicle simulation is important for developing and configuring control systems for autonomous vehicles. The vehicle simulation system imitates the movement or dynamic situation of the vehicle in reality, and generates the corresponding movement simulation result or dynamic simulation result of the vehicle. Specifically, in the prior art, the mechanical structure of the vehicle (such as the engine and transmission) is usually mathematically modeled to obtain a model, and corresponding parameter settings and adjustments are performed to obtain a perfect model, and the model calculation is performed on real-time input to obtain the vehicle. Motion simulation or dynamic simulation. [0003] Since the driving environment in the real world is various, the situation of the vehicle is...
