Abstract

The invention discloses a method and device for repairing flashing error data in an electronic control unit. The method and device can be applied to repair equipment. The repair equipment is connectedwith the electronic control unit through a preset interface. The method comprises the steps of acquiring vehicle identification information of a vehicle corresponding to the electronic control unit;based on the vehicle identification information, obtaining a current secret key of the electronic control unit and correct data corresponding to error data flashed to the electronic control unit; andafter unlocking the electric control unit based on the current secret key, flashing the correct data to the control unit. By applying the method and the device, in the whole repairing process, a vehicle does not need to be disassembled and assembled to replace a new electric control unit and other related parts, and a user does not need to manually calculate and manually modify error data piece bypiece. 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 flashing 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...
