Claim 20:
21. The electrical control device detection method according to claim 13, wherein the “obtaining an electrical signal at a third end of a first detection module, and determining, based on the electrical signal at the third end of the first detection module, whether a fault occurs in a drive circuit of an electrical control device” specifically comprises:
closing a second switch module when a high-side switch unit and a low-side switch unit are in an enabled state and a first switch module is in an off state; and
monitoring the electrical signal at the third end of the first detection module in real time; and
determining, if it is determined that a level of the electrical signal at the third end of the first detection module is not a second level, that a fault occurs in the drive circuit of the electrical control device.
