Description

technical field [0001] The invention belongs to the technical field of fault simulation testing of automobile controllers, in particular to a hardware-in-the-loop simulation system of a PTC controller. Background technique [0002] With the continuous development of new energy vehicles, more and more PTC controllers are applied to new energy vehicles. The number of integrated controllers increases and the functions become more and more complex. Complex functions make the testing and calibration of the controllers more important. . In the process of controller development, in order to reduce development time, control costs and improve competitiveness, it is very necessary to realize software verification before the product control board is produced. [0003] The currently used PTC controller software verification method is to perform fault diagnosis tests on the bench or on the whole vehicle. Due to the cumbersome and complicated testing process, high test repeatability and...
