Abstract

The invention relates to a driver-in-the-loop vehicle performance optimizing simulation testing system and belongs to the technical field of electronic control of vehicles. The simulation testing system comprises a driver operation platform, a target machine controller, a target control generating unit and a target vehicle model unit, wherein the target machine controller is in communication connection with the target control generating unit and the target vehicle model unit, the target control generating unit comprises an automatic code generating and compiling module and a matrix laboratory (Matlab) / Simulink module, the Matlab / Simulink module is used for establishing a vehicle control strategy, and the automatic code generating and compiling module is used for converting the control strategy into a control code of the target machine controller. According to the driver-in-the-loop vehicle performance optimizing simulation testing system, the automatic code of the target machine controller is used for generating a kit, a control algorithm established by the Matlab / Simulink module is loaded in a target machine for running in a one-button mode through the automatically generated code, online verification and adjustment of the control algorithm are achievable through an online parameter adjusting interface, and parameters of the vehicle can be adjusted. The driver-in-the-loop vehicle performance optimizing simulation testing system has the advantages of being small in investment, convenient to construct, low in cost, efficient, easy to maintain, and good in timeliness.

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 ...
