Problems solved by technology

If there is no HIL test equipment, the logic verification of the whole vehicle can only be carried out on the real vehicle, and the development of the real vehicle takes a long time. At the same time, the real vehicle verification will cause delays in fault exposure and affect the development cycle of the whole vehicle

Abstract

The invention relates to an offline vehicle logic test system and test method. The system comprises a controller to be tested, a quick plug box, an external accessory, a signal collector, a switchingpower supply, a CAN module and an upper computer. The offline vehicle logic test system is practical in controller function adaptability change verification or verification of only newly added function logic, is high in integration level, high in applicability and convenient to use, and is more suitable for development requirements of various conventional controllers of medium and small companies.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicle testing, in particular to an offline vehicle logic testing system and testing method. Background technique [0002] In new energy vehicles, the vehicle controller is responsible for core functions such as driving intention recognition, high voltage power on and off, power distribution, accessory control, and fault handling. In the development process of the vehicle controller, HIL (Hardware-In-The-Loop) testing is generally required before the actual vehicle test, but basically a special HIL test bench is required, and the cost of the bench equipment is high, and it requires a lot of investment. More human resources and time to complete the vehicle logic test HIL. If there is no HIL test equipment, the vehicle logic verification can only be performed on the real vehicle, and the development of the real vehicle requires a long period. At the same time, the real vehicle verification will...
