Abstract

The present application discloses a repair method and device for writing wrong data in an electronic control unit. The method and device can be applied to repair equipment, and the repair equipment is connected to the electronic control unit through a preset interface. The method includes : Acquiring the vehicle identification information of the vehicle corresponding to the electronic control unit; based on the vehicle identification information, obtaining the current secret key of the electronic control unit and the correct data corresponding to the wrong data written to the electronic control unit; After the electronic control unit is unlocked based on the current secret key, the correct data is flashed to the control unit. The application of the method and device can make the whole rework process unnecessary to disassemble and assemble the vehicle to replace new electric control units and other related components, and also does not require the user to manually calculate and manually modify error data one by one. Therefore, the repair cost of the electronic control unit can be reduced, the repair time can be shortened, the production efficiency can be improved, and the writing errors caused by manual calculation can be reduced.

Description

technical field [0001] The present application relates to the field of computers, and in particular to a repair method and device for flashing wrong data in an electronic control unit. Background technique [0002] Electronic Control Unit (Electronic Control Unit, ECU), referred to as the electronic control unit, is the comprehensive control device of the vehicle. During the vehicle production process, data such as vehicle information (such as vehicle identification number (VehicleIdentification Number, VIN)) and control programs need to be flashed to the electronic control unit. [0003] In the actual production process of the vehicle, there will be a situation where the data of the electronic control unit is written incorrectly, and it needs to be repaired at this time. At present, there are two methods for repairing, one is to replace the electronic control unit that flashes the correct data; the other is to manually query the wrong data that has been written and the cor...
