Description

technical field [0001] The invention belongs to the technical field of vehicle controller design and testing, and in particular relates to a semi-physical simulation platform for vehicle controller testing. Background technique [0002] The on-board controller (Carbone Controller) is a secure computer platform used in rail transit control systems, mainly composed of a series of boards with functional modules. The on-board controller is mainly used to collect signals from on-board sensors such as speed sensors, acceleration sensors, Doppler radars, and beacon finders in high-speed rail lines or subway lines. [0003] With the advancement of science and technology and the development of the times, more and more automated control systems are used in subway and high-speed rail lines. As an inaccessible part of subway or high-speed rail trains, on-board controllers are tested and certified to ensure safety. missing part. In the process of R&D and testing of the on-board control...

AI Technical Summary

Problems solved by technology

However, these simulated sensor signals are still very different from real sensor signals, and even if a hardware-in-the-loop simulation system is established for a certain sensor, it can only test the single performance of the vehicle controller from one aspect

It is not possible to comprehensively test all the performance of the on-board controller

And due to the lack of the operating environment and scenarios of the on-board controller, these test systems are still very incomplete and complete in testing the on-board controller
