Title:
VEHICLE MCU FAILURE CONTROL CIRCUIT AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/093269
Kind Code:
A1
Abstract:
Provided is a vehicle MCU failure control circuit. The circuit comprises: a failure state detection module (11), which is used for monitoring the state of an MCU module in real time; a maintenance voltage signal generation module (10), which is used for converting, when it is detected that the MCU module fails, the voltage of an ignition coil of a vehicle, so as to form a failure maintenance voltage signal; and a driving maintenance module (12), which is used for outputting the failure maintenance voltage signal to a driving control module of each load in the vehicle, so as to maintain the normal operation of the driving control module. Further provided is a corresponding method. It can be guaranteed that after an MCU module fails, functions such as power source hold, headlights, wipers and door locks of a vehicle are not affected, and can only be continuously used, such that the safety of an automobile circuit can be improved, and the safety during a traveling process is improved.
