Embodiment Construction

[0044] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0045] figure 1 It is a schematic structural representation of the ECU upgrading device in the embodiment of the present application; as figure 1 As shown, an ECU upgrade device in the present application mainly includes a wireless refresher and a server, and the server is provided with a network server module for network services, an authentication server module for authentication services, and an authentication server module for ECU upgrade operations. Refresh module and access control interface; in the actual upgrade operation, the above-mentioned wireless refresher can be plugged or connected to the ECU to be upgraded through other wired or wireless methods (for example, it can be plugged into the OBD (On-Board Diagnostic) of the car. Diagnosis system), so that the ECU of the car communicates with the wireless refresher), and at this time the...

Abstract

The invention discloses an ECU (Electronic Control Unit) upgrading device and a method, and relates to the technical field of vehicle electron. On the basis of the traditional ECU upgrading protocol and the device, a wireless communication module is integrated on an ECU upgrading device, dual authentication of network authentication and CA authentication are based, a server can thus use wireless signals to be in communication connection with one or more to-be-upgraded ECUs at the same time, that is, on the premise of ensuring safe, reliable and accurate upgrading, upgrading operation can be carried out on to-be-upgraded ECUs on one or more vehicles at the same time, the operation is flexible and convenient, manpower and time cost are greatly saved, and the ECU upgrading efficiency can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to an ECU upgrading device and method. Background technique [0002] At present, automobile manufacturers often need to upgrade the ECU (Electronic Control Unit, Electronic Control Unit) of the vehicle during vehicle recall and technology update; ECU upgrade (Electronic Control Unit), also known as refresh ECU or ECU tuning, mainly through rewriting The method of program is to fine-tune the fuel supply and ignition on the basis of the original factory data, optimize parameters, etc. to achieve the purpose of increasing output horsepower, increasing torque or reducing fuel consumption; since the essence of ECU is a driving computer, once the ECU upgrades wrong, it will It brings great hidden dangers to driving safety, so it is necessary to ensure the safety, reliability and accuracy of ECU upgrades. [0003] The existing method is to drive the vehicle into the 4S shop...
