Abstract

PURPOSE: To control a transmission to a prescribed speed change shift and prevent a trouble before its occurrence when the signal of line pressure shows an abnormal value, by providing an abnormal value detecting circuit in an input part of the signal from a line pressure sensor in an electronic controller.
CONSTITUTION: Shift lever position signals 202W204, a throttle opening signal 206, car speed signal 205 and a line pressure signal 207 are input to an abnormal value detecting circuit 1000. Said circuit 1000 consists of abnormal value detecting circuits 1010W1040 corresponding to each of the above described signals and generates an abnormal value detected signal 1052a if an abnormal signal is transmitted from any one of the circuits. Here the line pressure abnormal value detecting circuit 1040 is provided with a timing circuit comprising a line pressure decision circuit, that includes a comparator 1045 for comparing an input signal with preset minimum and maximum values, and a comparator circuit 1049 for generating an abnormal decision signal when a signal for showing the output of said line pressure decision circuit not within both of the above described minimum and maximum values lasts for not less than the prescribed time.
