Abstract
PURPOSE:To prevent a catalyst from being damaged by melting by selecting an abnormal speed change point as the speed change point in a shift map and a speed change shift with speed change ratio larger than in the normal time, in the case of an operating condition in which a temperature of the catalyst exceeds its predetermined threshold value by generating after combustion. CONSTITUTION:The captioned control device is equipped with an engine control unit 13 controlling air-fuel ratio of an engine and its ignition timing or the like and an EAT control unit 14 controlling the shift operation of an electromagnetically operated automatic transmission 12. Here in the EAT control unit 14, an abnormality discriminating part 16, which discriminates whether or not a catalytic temperature calculated by an arithmetic part 15 is in a threshold value or more from an output of a catalytic temperature sensor 9, is provided. When the result of discrimination is YES, selecting an abnormal speed change point, set to a low car speed side from the normal speed change point, as the speed change point in the high speed region of a shift map by a shift map decision part 17, a speed change shift is controlled to be decided.
