Abstract

The invention relates to an automatic gearbox controller semi-physical simulation test system. The automatic gearbox controller semi-physical simulation test system comprises a real object part and a virtual simulation part. The real object part comprises an automatic gearbox controller and a data collection board which is used for collecting structural parameters and operating parameters of a to-be-tested automobile. The virtual simulation part comprises an upper computer and a test machine, the upper computer is used for setting up an automatic gear shifting algorithm model, and the test machine is used for setting up a semi-physical simulation model. The data collection board is used for being connected with the to-be-tested automobile through a sensor and respectively connected with the upper computer and the test machine through universal series bus (USB) interfaces, the upper computer is connected with the test machine through a serial interface, the automatic gearbox controller is respectively connected with the test machine and the upper computer through joint test action group (JTAG) interfaces, and the problems that a danger coefficient is high and cost is high when an automatic gearbox controller is installed on a real automobile for a test in a later stage of development of automatic gearbox electronic control system are solved.

Description

technical field [0001] The invention relates to a semi-physical simulation test system for an automatic transmission controller. Background technique [0002] With the development of vehicle electronic technology, people's requirements for vehicle performance are also increasing, and the function and complexity of automatic transmission electronic control unit (ECU) are also increasing. This development trend makes the development of automatic transmission ECU more time-consuming and cost-effective. strenuous. Traditional automatic transmission software development requires manual coding, is highly dependent on hardware, requires high-quality technical personnel, is difficult, inefficient, has many errors, and has a long development cycle. In the later stage of the development of the automatic transmission electronic control system, it is necessary to install the controller on the real vehicle for testing, which requires high site requirements, and has the disadvantages of ...
