Embodiment 1

[0035] This embodiment provides an anti-theft controller detection device, which includes:

[0036] The simulated key unit is used to simulate the key to send authentication information to the anti-theft controller.

[0037] The analog engine control unit is used for mutual authentication between the analog engine controller and the anti-theft controller.

[0038] The result output unit connected with the analog key unit and the analog engine control unit is used to output the detection result.

[0039] The connection end connected with the analog key unit and the analog engine control unit is used to connect the anti-theft controller.

[0040] It can be seen that the anti-theft controller detection device of this embodiment can simulate other units in the engine electronic locking anti-theft system to accurately detect whether the anti-theft controller can work normally; therefore, the quality of the anti-theft controller can be tested before loading the car , if there is a...

Embodiment 2

[0042] Such as figure 2 As shown, this embodiment provides an anti-theft controller detection device, which includes:

[0043] The simulated key unit is used to simulate the function of the key and send authentication information, such as encrypted authentication code, to the anti-theft controller. Of course, unlike the real key, the authentication information is not sent wirelessly, but can be sent directly through the data line, and the simulated key unit does not include the mechanical key part. The authentication code and key used by the analog key unit for authentication can be obtained from the anti-theft controller, or can be provided to the anti-theft controller by the anti-theft controller detection device (that is, the anti-theft controller uses the anti-theft controller when detecting) The authentication code and key provided by the detection device), or a pre-set authentication code and key specially used for detection.

[0044] The simulated engine control unit...

Embodiment 3

[0051] This embodiment provides a detection method for an anti-theft controller, which includes the following steps:

[0052] S01. Connect the anti-theft controller to the connection end of the anti-theft controller detection device in the above embodiment.

[0053] S02. The anti-theft controller authenticates the analog key unit of the anti-theft controller detection device, and performs mutual authentication with the analog engine control unit of the anti-theft controller detection device.

[0054] S03. The anti-theft controller detection device output unit outputs a detection result according to the authentication result in S02.

[0055] It can be seen that the detection method of the anti-theft controller in this embodiment can accurately and independently detect whether the anti-theft controller can work normally; car, setting keys, etc., the operation is simple; at the same time, for the faulty car, it can accurately detect whether the problem lies in the anti-theft con...

Abstract

The invention provides equipment and a method for detecting a theftproof controller, belongs to the technical field of locking and theft prevention of automobile engines, and aims to solve the problem that the theftproof controller cannot be detected independently during production of a whole automobile. The equipment for detecting the theftproof controller comprises a key simulation unit for simulating a key to send authentication information to the theftproof controller, an engine control simulation unit for simulating mutual authentication between an engine control module and the theftproof controller, a result output unit for outputting a detection result, and a connection end which is connected with the theftproof controller. The method for detecting the theftproof controller comprises the following steps of: connecting the theftproof controller and a connection end of the equipment for detecting the theftproof controller; authenticating the key simulation unit of the equipment for detecting the theftproof controller by the theftproof controller, and mutually authenticating the theftproof controller and the engine control simulation unit of the equipment for detecting the theftproof controller; and outputting the detection result by the result output unit of the equipment for detecting the theftproof controller according to authentication results.

Description

technical field [0001] The invention belongs to the technical field of automobile engine locking and anti-theft, and in particular relates to an anti-theft controller detection device and a detection method. Background technique [0002] The electronic anti-theft system of automobile engine (IMMO, Immobilizeir) has been more and more widely used because of its superior security. The engine electronic locking and anti-theft system can authenticate the authentication code (ID) stored in the key. If the authentication is not passed, the fuel injection and ignition will be stopped to prevent the unauthorized start of the vehicle. Therefore, even if someone opens the door, it cannot be forcibly shorted, It is also equipped with a mechanical key to start the vehicle. [0003] Conventional electronic engine locking anti-theft systems include: [0004] Key, which includes a conventional mechanical key part (that is, the part used to insert the ignition lock and turn the ignition) ...
