Description
Technical Field
The utility model relates to the field of automotive technology, in particular to ECU flash mistake proofing system.
Background
In the software flashing of a traditional Electronic Control Unit (ECU), two error-proofing methods are generally available, one is to stick a label on an ECU shell, and an operator identifies the ECU through the label; and the other is to directly identify the ECU through the shape.
With the development of the automobile industry, the competition of the automobile industry is more and more intense, the number of vehicle types produced by each host factory is increased, and the configuration of vehicles is more and more complicated. The inventor of the invention researches and discovers that not only the same ECU can be from different manufacturers, but also the same ECU produced by the same manufacturer can have different configurations, so that the ECU can not be identified at all in appearance; however, if the label is attached to the ECU housing, the label may be easily worn due to factors such as time and environment, and the label may not be visible or recognizable by an operator. Therefore, the ECU is distinguished in a traditional manual mode, so that the ECU is easily subjected to software package error writing, and the accuracy of software writing is low.

the detection unit is used for detecting whether the software package to be written corresponds to the ECU or not;
the control unit is used for controlling the judging unit, the detecting unit, the flashing unit and the error reporting unit to work;
the flash unit is used for performing flash operation on the ECU;
the error reporting unit is used for carrying out error reporting operation.
Optionally, the flash device further includes a second detection unit, and the second detection unit is electrically connected to the control unit;
the second detection unit is used for detecting whether the ECU is in place.
Optionally, the determination unit determines the hardware type of the ECU by detecting a voltage value between pins 48 and 64 of the ECU.
