Abstract

The invention provides an automatic testing device for monitoring the port state of a controller. The automatic testing device comprises an upper computer and the controller, wherein the upper computer is in communication with the controller through a CAN bus, the upper computer is used for sending a detection instruction to the controller and judging the port state of the controller according to execution results fed back by the controller, and the detection instruction comprises the maximum number of response times; the controller is used for receiving the detection instruction, verifying effectiveness of the detection instruction, responding to the detection instruction so as to obtain the execution results when the detection instruction is effective, and feeding back the execution results to the upper computer until the number of response times of the controller reaches the maximum number of response times. The automatic testing device can monitor the state of the controller in real time and guarantee automobile running safety, and is simple in structure and low in cost. The invention further provides an automatic testing method for monitoring the port state of the controller.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an automatic test device for monitoring the state of a controller port and an automatic test method using the automatic test device. Background technique [0002] With the rapid development of electronic technology, the number of electronic systems installed in automobiles is increasing. Among them, ECU (Electronic Control Unit, electronic controller), as the core component of the control system, determines the stability and reliability of the control system. Therefore, it is necessary to obtain the state of the ECU in real time in order to control the driving of the car well. [0003] If the ECU is not functionally tested, the reliability of the ECU cannot be guaranteed, which will inevitably bring great risks to vehicles and personnel. [0004] The disadvantage of the prior art is that the state of the ECU cannot be monitored in real time, and the reliability...
