Abstract
A method and apparatus for analyzing a signal delay time based on controller area network (CAN) burst are disclosed. An apparatus for analyzing a signal delay time, connected to a controller area network (CAN) bus includes a measuring device configured to determine a transmission start time based on a receiving time point of a CAN signal and to determine a receiving time interval between the CAN signals that are continuously received, a fixer configured to fix a burst period corresponding to CAN signals with the determined receiving time interval less than a predetermined value, a selector configured to select an analysis target CAN signal in the fixed burst period, and a determiner configured to determine a maximum transmission delay time 'a' corresponding to the selected CAN signal.
