Automobile semi-physical simulation experimental system combining controller area network (CAN) bus and electronic control unit

Abstract

The invention discloses an automobile semi-physical simulation experimental system combining a controller area network (CAN) bus and an electronic control unit, and belongs to the technical field of automobile design and development. The automobile semi-physical simulation system mainly comprises two parts: an entity part and a virtual simulation part, wherein the entity part is connected with the CAN bus through all systems including wheels, a frame, a power system and sensors of all control systems on an automobile chassis; the CAN bus is connected with the virtual simulation part through the electronic control unit; the virtual simulation part comprises a road view and a mathematical model; physical hardware is embedded into the simulation system; a software and hardware technique and an electronic technique are combined together; a computer is used for establishing a virtual model for reflecting an objective law; the virtual model is used for performing experiments; and certain acquired key signals are sent out by real hardware. The automobile semi-physical simulation system saves the cost compared with pure hardware, and has higher reliability compared with pure software.

Description

technical field [0001] The invention belongs to the technical scope of automobile design and development, and in particular relates to a semi-physical simulation experiment system combined with an automobile CAN bus and an electric control unit. Background technique [0002] The traditional automobile test is carried out in kind, which is time-consuming, laborious and expensive; the second is the danger and inconvenience of using real objects for education or training; when using real objects, if the operator makes a mistake, it may Destructive accidents will occur, which will harm the operator, endanger the environment, and cause negative impacts such as property loss. [0003] Using semi-physical simulation technology to replace some systems in the car with software, and to test the performance of the car or the electrical system, can be used as a preparatory work for a real test and can replace traditional tests to a certain extent. It overcomes the danger and inconvenie...
