Embodiment Construction
[0049] In the following, only some exemplary embodiments are briefly described. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. Accordingly, the drawings and descriptions are to be regarded as illustrative in nature and not restrictive.
[0050] An embodiment of the present invention provides an automatic driving simulation running method, such as figure 1 shown, including the following steps:
[0051] S100: Obtain scene data and vehicle-side driving strategies. Vehicle-end driving strategy includes decision-making model. The decision model is used to calculate the driving trajectory of the vehicle within a certain period of time in the future. It should be noted that the acquired scene data may be real data collected by the vehicle during actual road driving, or artificially customized virtual data.
[0052] S200: Construct a simulation...

The embodiment of the invention provides an automatic driving simulation operation method and device. The method comprises the steps of: acquiring scene data and a vehicle end driving strategy, with the vehicle end driving strategy comprising a decision model; constructing a simulation scene according to the scene data; based on the vehicle end driving strategy, performing simulation driving of the vehicle in the simulation scene; enabling a decision model to acquire driving environment data of the vehicle in a simulation driving process and calculating planned driving strategy data of the vehicle, wherein the driving environment data comes from the scene data; and verifying the decision model according to the planned driving strategy data of the vehicle. According to the embodiment of theinvention, the driving condition of the vehicle can be simulated in a simulation mode based on the scene data and the vehicle end driving strategy, the driving performance of the vehicle can be accurately verified and tested, and test in a real road environment is not needed.
Description
technical field [0001] The invention relates to the technical field of automatic driving, in particular to an automatic driving simulation operation method and device. Background technique [0002] The development of self-driving cars has been able to realize the function of self-driving in closed and open roads. However, in the face of various complex elements in the traffic environment, self-driving cars will always have problems that cannot be dealt with and dealt with, requiring human driving. staff take over. For this, the self-driving car industry needs to verify the safety of self-driving cars. But in the development process of self-driving cars, existing verification methods usually use actual self-driving cars to drive in real environments for testing. On the one hand, this method increases the test cost. On the other hand, it is easily restricted by road test scenarios and traffic environments. It is difficult to test dangerous and accident conditions. Therefore,...
