Problems solved by technology

[0005] It can be seen that the ECU has become an important constituent unit of a car, therefore, it has naturally become one of the main targets of thieves. At present, the main control parts of cars are often stolen on the market and flow into the black market, causing car owners or OEMs to a certain extent. property loss

Embodiment Construction

[0028] Introduced below are some of the various embodiments of the invention, intended to provide a basic understanding of the invention. It is not intended to identify key or critical elements of the invention or to delineate the scope of protection.

[0029] The present invention mainly detects whether a module is replaced, whether there is a potential vehicle theft, and if there is such a potential danger, the vehicle is not allowed to start.

[0030] Refer below Figure 1 ~ Figure 3 The method of detecting whether a vehicle module is replaced according to the present invention will be described.

[0031] figure 1 is a flow chart of the method for detecting whether a vehicle module is replaced in the present invention.

[0032] The method for detecting whether a vehicle module is replaced in the present invention is a method for detecting whether a plurality of detected modules are replaced by a main control unit of the vehicle. Here, the detected modules may be, for exa...

Abstract

The invention relates to a method for detecting whether modules of a vehicle are replaced or not. The method comprises the following steps that a main control unit of the vehicle automatically generates a random code during factory matching and transmits the random code to detected modules and the random code is stored in each detected module; when the vehicle is begun to be used, a detection function is activated; the main control unit periodically sends the random code to the detected modules, and the detected modules judge whether the random code stored in respective detected modules is consistent with the random code currently received from the main control unit or not. According to the method for detecting whether the modules of a vehicle are replaced or not, whether the modules in the vehicle are replaced or not and whether potential theft exists or not can be detected.

Description

technical field [0001] The invention relates to a vehicle detection technology, in particular to a technology capable of detecting whether a main module in a vehicle has been replaced. Background technique [0002] ECU (Electronic Control Unit) electronic control unit, also known as "driving computer", "vehicle computer" and so on. In terms of use, it is a special microcomputer controller for automobiles. Like an ordinary computer, it consists of a microprocessor (CPU), a memory (ROM, RAM, EEPROM), an input / output interface (I / O), an analog-to-digital converter (A / D), and shaping and driving. Composition of integrated circuits. To use a simple sentence to describe it is "ECU is the brain of the car". [0003] At present, in some mid-to-high-end cars, ECU is not only applied to the engine, but also can be found in many other places. For example, ABS anti-lock braking system, electronically controlled automatic transmission system, active suspension system, SRS airbag sy...
