Abstract

PURPOSE: To control an engine on the low revolution and secure safety operation by detecting the full open or close status of an accel pedal and assuming a potentiometer to be abnormal if the output of the potentiometer is a value exceeding a specified value.
CONSTITUTION: When an accel pedal 101 is stepped in, the slider 104 of a potentiometer 100 is moved through a rod 102 and output voltage VA is issued depending upon its move. Then this voltage VA is compared with the specified voltage VO by the comparator 115 of an arithmetic circuit 113. In this case, when an error occurs in the potentiometer 100 and when VA≥VO during the full close, an accel pedal full close detection switch 106 is set to ON. In this case, the collector voltage of a trasistor 107 which receives the output of a comparator 105 becomes high and an FF114 is set. Subsequently, the Q output of the FF114 is output as a decision signal and an abnormal display unit 108 and a change-over unit 109 are actuated. As a result, a fuel injection valve is controlled based on the specified low voltage VS.
