Problem of matching the simulated speed of a data set with the real set speed

[UESTC-LU]

What feature are you suggesting?

Overview:

Currently I'm working on vehicle IMU data acquisition, using Python's API, I import the vehicle position frame by frame and acquire the IMU data, but there's a problem: in UE4 the vehicle speed is related to the simulation speed, not to the original frame rate, is there a setting or a better API to provide time information to the simulation while setting the vehicle position?

Smaller Details:

Here's the API I use and the data format imported by the vehicle simulation

Which vpose[0]-vpose[5] represent respectively x y z roll pitch yaw
Here's the main code:
