A method for judging engine anti-theft configuration

Abstract

The present invention provides a method for judging engine anti-theft configuration, which can conveniently distinguish and set whether the whole vehicle has an engine anti-theft function, thereby reducing production costs and reducing the risk of vehicle rework and vehicle theft. The specific steps are as follows: A: Set the configurable anti-theft function variable in the engine anti-theft function software of the engine controller; set the configurable first anti-theft function variable identification bit in the engine controller, and set the configurable anti-theft function variable in the body controller The second anti-theft function variable identification bit; B: When the vehicle is off the assembly line, use the offline device to scan the configuration barcode of the whole vehicle, according to whether there is the configuration information of the engine anti-theft function reflected on the configuration barcode of the whole vehicle, through the diagnosis of the engine controller The service configures the anti-theft function variable, the first anti-theft function variable identification bit, and the second anti-theft function variable identification bit; and stores the anti-theft function variable, the first anti-theft function variable identification bit and the second anti-theft function variable identification bit.

Description

technical field [0001] The invention relates to engine anti-theft technology, in particular to a method for judging engine anti-theft configuration. Background technique [0002] At present, in order to distinguish whether the whole vehicle has the engine anti-theft function, the engine controller mainly distinguishes the anti-theft settings through the hardware difference of the peripheral wiring harness. First of all, this method increases the types of wiring harnesses and engine controllers, and the cost of production and management is high; secondly, there is no difference in appearance between wiring harnesses and engine controllers with or without engine anti-theft function, and it is easy to cause wiring harnesses and engine controls during the production process. The wrong installation of the device will cause rework; finally, the anti-theft distinction and setting through the wire harness is relatively simple, and it is easy to crack the anti-theft by adjusting the ...
