Abstract

The invention provides an ECU flashing fault processing method and device, electronic equipment and a storage medium, and the method comprises the steps: detecting whether the state of an ECU is a dead flashing state or not in real time in a process that the ECU flashes required data; if it is detected that the state of the ECU is a swipe-dead state, the ECU is controlled to enter a security access diagnosis service; acquiring backup data of the ECU from an ROM (Read Only Memory) of the ECU, and detecting whether the ECU is activated or not according to the backup data; and if the ECU is successfully activated, re-writing the required data by using the activated ECU. Based on the method and the device, the cost can be reduced, and the ECU flashing efficiency can be improved.

Description

technical field [0001] The present application relates to the technical field of engines, and more specifically, relates to a method, device, electronic equipment and storage medium for ECU flashing fault handling. Background technique [0002] During the flashing process of the electronic control unit (Electronic Control Unit, ECU), the phenomenon of "flashing" of the ECU often occurs. In the process of data upgrade or equipment maintenance in the market, the ECU is flashed. If the ECU is "flashed" many times, it will have a great adverse effect on the equipment. [0003] At present, the common way to deal with the ECU "flash dead" phenomenon is: replace the ECU; or use tools such as WISETOOL to force flash to reactivate the ECU. However, the former of these two methods will increase the cost, and the latter needs to reconnect other devices to activate the ECU, resulting in low work efficiency. Contents of the invention [0004] In view of this, the present application ...
