Problems solved by technology

The diagnostic instrument consists of an upper computer and a lower computer, limited by the networking and storage capabilities of the lower computer, the upper computer obtains firmware from the server for storage, and then flashes it, or obtains firmware from the ECU for storage, and then uploads it to the The server is backed up, and the lower computer is only used for simple data transparent transmission. This method leads to more interactions between the upper and lower computers and takes a long time, and the above method has high requirements for the stability of the connection between the upper computer and the lower computer. Usually not suitable for wireless scenarios, affecting user experience

Abstract

The invention provides a vehicle ECU firmware flashing backup system which comprises an upper computer and a lower computer, and the lower computer comprises a first communication module used for being connected with the upper computer, a second communication module used for being connected with a server through a network, a CAN module and an OBD interface used for being connected with a vehicle ECU, a storage module and a control module. The first communication module is connected with the upper computer, the CAN module is connected with the OBD interface, and the control module is connected with the first communication module, the second communication module, the CAN module and the storage module. According to the invention, the networking capability and the storage capability are added to the lower computer, and on the basis, the lower computer can quickly acquire the ECU firmware and flash or back up the ECU firmware, so that frequent interaction between the upper computer and the lower computer is avoided, the efficiency and the stability are improved, and the method is suitable for a wireless scene and improves the user experience.

Description

technical field [0001] The invention belongs to the technical field of vehicle diagnosis, and in particular relates to a vehicle ECU firmware flashing backup system. Background technique [0002] At present, in the development process of the whole vehicle or ECU, the ECU is usually flashed or the firmware in the ECU is backed up through the diagnostic equipment. The diagnostic instrument consists of an upper computer and a lower computer, limited by the networking and storage capabilities of the lower computer, the upper computer obtains firmware from the server for storage, and then flashes it, or obtains firmware from the ECU for storage, and then uploads it to the The server is backed up, and the lower computer is only used for simple data transparent transmission. This method leads to more interactions between the upper and lower computers and takes a long time, and the above method has high requirements for the stability of the connection between the upper computer and ...
