Method, device, medium and electronic equipment for adjusting the speed of simulation process

Abstract

The present disclosure relates to a method, apparatus, medium, and electronic device for adjusting the speed of a simulation process. The method comprises the following steps of responding to a received control instruction for representing acceleration or deceleration of a control simulation process, respectively determining second frequency for sending messages to each simulation module accordingto first frequency for sending messages to each simulation module in the simulation process, wherein if the control instruction represents acceleration, the second frequency of any simulation moduleis greater than the first frequency of the simulation module, and if the control instruction represents deceleration, the second frequency of any simulation module is less than the first frequency ofthe simulation module; and sending a trigger instruction carrying a time stamp to the simulation module corresponding to the second frequency according to each second frequency, wherein the time stampis used for indicating the virtual time of a time server when the trigger instruction carrying the time stamp is sent. Therefore, the acceleration or deceleration of the simulation process can be realized, the time spent by the simulation process is freely controlled, and the development of research personnel is facilitated.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular, to a method, device, medium and electronic equipment for adjusting the speed of a simulation process. Background technique [0002] At present, autonomous driving has become a hot topic in the field of vehicles. The realization of autonomous driving requires the completion of a large number of test tasks. In order to avoid unnecessary losses during the actual test process, traffic simulation technology is generally used to complete the test in a simulation environment. To save money and reduce the risk of equipment damage. An important parameter in the simulation technology is the simulation time. In the existing simulation process, the simulation time generally refers to the actual time, and the timing standard is also the same as the actual time. The process must spend the same amount of time A as the simulation. Taking the simulation test for the automatic driving s...

Problems solved by technology

For a single test task, if there is a task content that occurs very quickly in a short period of time in the test task, since the simulation time is the same as the actual time, it is impossible to conduct a detailed analysis of the task content, which is not convenient for researchers to develop; and for the mileage In terms of requirements, how much time does it take for the actual mileage of the vehicle to reach the mileage required by the test, and how much time will be spent in the simulation test, which will also lead to low simulation efficiency
