摘要：PURPOSE:To aim at improvements in learning control, by monitoring a program run signal out of a central processing unit, while making full use of a runaway monitoring circuit, which makes the CPU into an initial stage in time of trouble detection, and detecting the occurrence of reckless driving with its auto-rest signal. CONSTITUTION:A learning controller bearing the above caption is constituted of installing a central processing unit or the like so as to set up a controlled variable with a fundamental controlled variable determined as corresponding to the desired value, a feedback compensation value and a learning compensation value stored in random access memory. In this case, a runaway monitoring circuit outputting an auto-reset signal in time of trouble happening in a program run signal out of the CPU is installed. And, a flip-flop being set by the auto-reset signal and outputs a latch signal and a latch signal detecting device detecting whether or not the occurrence of the latch signal both are installed. And, when the latch signal exists there, data of the learning compensation value inside the RAM is put back to the initial stage value by a learning content initial stage setting device, while the flip-flop is made so as to be reset via a reset device.
