Zusammenfassung:	The invention relates to the technical field of vehicle engineering, and discloses a controller CAN signal test method comprising the following steps: S1, importing a test CAN signal; s2, analyzing the test CAN signal to obtain test data of the test CAN signal; s3, converting the test data into a CAN (Controller Area Network) message; s4, calling an API sent by a CAN signal provided by a transmission tool, and sending a CAN message to the controller to be tested through a CAN bus; s5, the controller to be tested receives the CAN message sent by the transmission tool, and the CAN message is published after being processed by the controller to be tested; and S6, comparing the CAN signal issued by the controller to be tested with the signal value of the test CAN signal analyzed in the step S2, if the results are the same, determining that the link of the controller to be tested has no problem, and if the results are different, determining that the link of the controller to be tested has a problem.
