PURPOSE:To optimize the line pressure control by calculating the degree of satisfaction for the representative data of a plurality of operation state parameters by using the evaluation function using a plurality of operation state parameters and judging the operation state. CONSTITUTION:An operation state parameter detection means carries out sampling for a plurality of operation state parameter state quantity including least the throttle valve opening degree and the engine revolution speed, and the time sequence data is prepared, and the representative data for each operation state parameter is prepared by a representative data preparing means. Then, a satisfaction degree calculating means calculates the satisfaction degree of each evaluation function on the basis of the representative data, by using the evaluation function using the previously determined plural operation state parameters, and an opening state judging means judges the snare traveling city traveling, high speed traveling, sports traveling, etc., from the degree of satisfaction. According to the result of judgement, the line pressure is corrected by a line pressure correcting means. Thus, the line pressure control for an automatic transmission can be performed properly. |
