Abstract

PURPOSE: To control a transmission to a prescribed speed change shift and prevent a trouble before its occurrence, when the signal of car speed shows an abnormal value, by providing an abnormal value detecting circuit in an input part for the car speed signal from a car speed sensor in an electronic controller.
CONSTITUTION: Shift lever position signals 202W204, car speed signal 205 and a throttle opening signal 206 corresponding to the load of an engine 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 when an abnormal signal is generated from any one of the circuits. At this time, in the abnormal value detecting circuit 1030 for the car speed, a timing circuit is provided including a comparator circuit 1034, which compares the car speed signal with a signal corresponding to a maximum car speed value of the vehicle and generates an output when the car speed signal exceeds said signal, and a comparator circuit 1038, which generates an abnormal value detected signal when the output of said car speed signal lasts for not less than a prescribed time.
