Method of detecting engine tuning of vehicle

Abstract

A method of detecting engine tuning of a vehicle is disclosed. The method of detecting illegal tuning of the vehicle may include obtaining and storing, by a controller, at least one of learning information including a variable value and a control value and engine state information at a time of controlling the vehicle while the vehicle is driven, as a learning value; comparing, by the controller, alearning value, which is newly obtained over time, with a prestored previous learning value; determining, by the controller, that a tuning chip for changing component performance in the vehicle is mounted when the learning value is changed and there remains a difference between the obtained learning value and the prestored previous learning value at a predetermined level or higher for a predetermined period of time; and creating and storing, by the controller, a tuning detection code when it is determined that the tuning chip is mounted.

Description

technical field [0001] The invention relates to a method for detecting engine modifications of a vehicle. More specifically, it relates to a method that can detect whether an external tuning chip is installed in a turbocharged vehicle to increase the output of the engine. Background technique [0002] In recent years, turbochargers, intercoolers, etc. that pressurize the combustion chambers with high-pressure air are additionally installed on high-performance engines to obtain high output. [0003] A turbocharger is a device that compresses air by using energy of exhaust gas, and supplies the compressed air to a combustion chamber of an engine. The combustion chambers of an engine equipped with a turbocharger can be filled with a large amount of air, with the result that, under supercharging, the fuel injection quantity can be increased in proportion to the increase in air. As a result, a turbocharged engine can achieve higher output than a naturally aspirated engine with ...

AI Technical Summary

Problems solved by technology

[0016] Specifically, since an external tuning chip can be easily installed by using an interchangeable cable without damaging the wiring in the vehicle, drivers often remove the illegal chip and then send the engine in for repair, but the vehicle manufacturer cannot obtain the installed tuning Evidence of the chips, and as a result, the vehicle manufacturer had to repair the vehicle free of charge during the warranty period
