Integrated simulation test system for automobile power chassis

Abstract

The invention discloses an integrated simulation test system for an automobile power chassis. The integrated simulation test system comprises an upper computer and a closed-loop simulation system, wherein the upper computer is provided with test software and establishes a whole automobile model, and the closed-loop simulation system establishes a communication relationship with the upper computer through an optical fiber communication system. According to the invention, a hardware-in-the-loop test system based on the multi-system controller is constructed, the electronic and electric appliance environment of the whole vehicle is simulated, and the system problems of function failure, function abnormality, logic fault, integrated signal error, interactive operation abnormality and the like of the controller are found in advance. According to the hardware-in-the-loop test scheme integrating the power assembly and the chassis controller, the test environment is closer to the whole vehicle environment than the single system test, the complex fault mode of interaction of the power assembly and the chassis appearing after sale is rapidly reproduced, the limit working condition possibly causing personnel harm in the whole vehicle test is verified, and all-weather automatic testing is realized.

Description

Technical field [0001] The present invention belongs to the field of automotive simulation test, in particular, involves an automobile power chassis integrated simulation test system. Background technique [0002] At present, the hardware of the traditional automotive electronics system is mainly for single-system construction test environments in the ring test, such as power controller hardware in the ring test, and the chassis controller hardware is tested in the ring test. This method has defects mainly: [0003] 1) Single system's test environment is large, and the interaction between the vehicle multi-system interaction between the vehicle is not validated in a single system environment, thus causing low test accuracy. [0004] 2) The problem of multi-system interaction is easy to leave to the whole vehicle stage to find that the later the problem discovers, the higher the cost of problem solving. [0005] 3) The actual use of the user is usually the complex scene of multi-s...
