Abstract: PURPOSE: An engine knock control method in a vehicle is provided to prevent output of an engine from lowering due to excessive delay of an ignition period caused by erroneous recognition of a control unit. CONSTITUTION: A vehicle operational state detecting device detects change data in operational state of a vehicle from the running vehicle(S100). A control unit receives the change data in operational state of the vehicle for judging whether an ignition period is delayed due to generation of a knock(S110-S120). If so, the control unit accumulates the frequency of ignition period delay and judges whether the frequency is more than a first set frequency(S130,S140). If so, the control unit judges that knocking control is abnormally executed(S150). The control unit stops the knocking control, and controls the ignition period and an air-fuel ratio according to the change in operational state of the vehicle(S160-S191).
