Abstract: PURPOSE: A device and a method for controlling anti-jerk in gear shifting are provided to improver the reference engine rpm operation procedure in the case of clutch off for transmission, thereby carrying out the anti-jerk properly and preventing the jerks and stumbles after gear shifting. CONSTITUTION: A method for controlling anti-jerk in gear shifting includes the steps of operating a reference engine rpm value(N_REF) by an input engine rpm value(N)(S200,S210), and operating a difference value(delta N_DIF) between N and N_REF(S220,S230). If the difference is higher than a threshold value, the input is determined as a clutch signal and a timer is driven to measure a transmission time(S270). If the transmission time is lower than a threshold value, a fuel amount is controlled(S290). If delta N_DIF is lower than the threshold value or the transmission time is higher than the threshold value, a first anti-jerk torque amount(TQ_AJ_1) is operated(S300). A weight value(F_clutch) is set according to the clutch signal(S310), and a weight value(F_gear) is set according to a gear stage value(S320). A second anti-jerk torque amount(TQ_AJ_2) is operated by input values from the above steps(S330).

Abstract: PURPOSE: A deciding method for a failure in an intake temperature sensor is provided to measure failure in the intake temperature sensor regardless of fastness of the intake temperature sensor or increase in intake temperature. CONSTITUTION: An ECU(Electronic Control Unit) reads voltage for intake temperature from an intake temperature sensor through a voltage converter. In case of the voltage under a minimum voltage, the intake temperature sensor is decided as being failed caused by short. In case of the voltage over a maximum voltage, the intake temperature sensor is decided as being failed by short. Otherwise, a voltage change is detected for being compared with a low critical voltage. In case of the voltage change under the low critical voltage, the sensor is decided as being failed by a low temperature idle. Moreover, the ECU decides failure in the intake temperature sensor caused by fastness by using interference and vehicle speeds in worming up section and cooling down section. Moreover, the failure in the sensor is decided by high temperature inferential failure by comparing cooling water temperature signal at initial state of an engine with the intake temperature.
