    • A controller for a transmission capable of preventing an occurrence of a gear squeak caused by a malfunction of a synchronization mechanism. The voltage determination section 24 performs a shift operation of a transmission by determining a control input Vin to a shift motor 13 so as to match an actual position Psc of a coupling sleeve 6 grasped by an actual position grasping section 21 with a target position Psc_cmd of the coupling sleeve 6 set by a target position setting section 22. After starting the shift operation of the transmission, it halts the shift operation by detecting a malfunction in the gear position where the shift operation is under execution when the actual position Psc of the coupling sleeve 6 has reached a malfunction judgment position provided within a range from a balk point to a contact point between the coupling sleeve 6 and an idle gear 7c before a difference Esc between the actual position Psc and the target position Psc_cmd of the coupling sleeve 6 exceeds a given contact judgment value.

    • A target value Vtgt for an output Vout of an O2 sensor 8 (an exhaust gas sensor) disposed downstream of a catalytic converter 4 is set variably depending on a temperature TO2 of an active element 10 of the O2 sensor 8 by a target value setting unit 18, and the air-fuel ratio of an exhaust gas is controlled by an air-fuel ratio control unit 17 to converge the output Vout to the target value Vtgt. An exhaust gas temperature Tgd is estimated by an exhaust temperature observer 19, and the temperature TO2 of the active element 10 is sequentially estimated by an element temperature observer 20 using the estimated value of the exhaust gas temperature Tgd. A heater 13 of the O2 sensor 8 is controlled by a heater controller 22 to keep the temperature TO2 of the active element 10 at a predetermined target value R. The air-fuel ratio is thus controlled to maintain a desired exhaust gas purifying capability of the catalytic converter irrespective of the temperature of the active element of the exhaust gas sensor.
