<p>The present invention relates to a method for diagnosing malfunction of an in-vehicle electronic control system, and it is an object of the present invention to provide a method for diagnosing malfunction of an in-vehicle electronic control system, which can diagnose malfunction of various electronic control systems mounted in the vehicle at a gateway interworking different vehicle networks of various kinds, such that there is no need to mount a malfunction diagnostic module to each electronic control system. The method for diagnosing malfunction of the in-vehicle electronic control system at the gateway interworking different vehicle networks includes the steps of: collecting first control values transferred from the electronic control systems through the vehicle networks; collecting information (diagnosis information) necessary for calculating the first control values through the vehicle networks; calculating a second control value by applying the collected diagnosis information to a formula to calculate the first control value; comparing the second control value with the first control value; determining that there is no malfunction in the electronic control system if the control values are equal as a result of comparison; and determining that there is a malfunction in the electronic control system if the control values are not equal as the result of comparison.</p> |
