Description

technical field [0001] The invention relates to a driver-in-the-loop vehicle performance optimization simulation test system, which belongs to the technical field of vehicle electronic control. Background technique [0002] With the introduction of the "V-cycle" mode of the modern vehicle development process, how to realize the online optimization and verification of the control strategy without developing the real vehicle controller - the rapid control prototype of the driver in the loop has become an important part of the vehicle development process. essential component. After searching the literature of the prior art, it is found that ZL102354121 A discloses a development method and its development platform for rapid prototyping. The platform is mainly designed based on Dspace. The disadvantage of running complex models is that the hardware equipment needs to be purchased specially, and the cost is too high; in the literature, a rapid control prototype platform based on ...
