摘要： An engine controller is provided with a microcomputer to effect an engine control through learning on data necessary to control the engine and storing learning results with respect to the data in the microcomputer, and automatically effects reset of the microcomputer when power supply voltage to the microcomputer drops below a predetermined level during an engine operation and initialization of the data after releasing the reset, wherein it is judged whether or not the reset is effected based on drop in the power supply voltage due to a normal operation, and the initialization is inhibited when the reset is effected based on drop in the power supply voltage due to a normal operation.
