Abstract
PURPOSE: To prevent any trouble which would occur in automatic transmission, by providing an engine load signal abnormal level detection circuit in an input section for a signal from the engine load sensor of an electronic controller to control a transmission in a prescribed speed step when the engine load signal has an abnormal level.
CONSTITUTION: Shift lever position signals 202W204, a vehicle speed signal 205, a throttle opening degree signal 206 corresponding to the load an engine, etc. are apaplied to an abnormal level detection circuit 1000. This detection circuit 1000 comprises abnormal level detection circuits 1010W1040 corresponding to said signals. When an abnormlaity signal is generated by either of the circuits, an abnormal level detection signal 1052a is produced by the circuit 1000. An abnormal level detection circuit 1020 for throttle opening degree signal comprises a load discrimination circuit including a comparison circuit 1024 which compares an input signal with the maximum and minimum levels of set engine load and a timing circuit including a comparator 1027 which generates an abnormal level detection signal when a signal showing that the load on the engine is not within the range of both the values has lasted for more than a prescribed time.
