ENGINE CONTROL UNIT FUNCTION FAILURE DIAGNOSIS CONTROLLING METHOD OF TRACTION CONTROL SYSTEM

摘要

This invention is a response of the engine control to output a torque that is reduced by the torque reduction demand of the traction control system and determining the gender , the engine control unit side malfunction condition relates to the engine control fault diagnosis method of controlling a vehicle fitted with traction control system capable of warning , to compare the value of the first signal set (TQI_TCS) and the second signal (TQI_ACOR) and is characterized in that when the predetermined value is a required amount of the engine control by the traction control system failure (ECU) (TCS) does mistimed well to a fault diagnosis to alert the engine control unit (ECU) failure condition .
