PROBLEM TO BE SOLVED: To provide an electronic controller for vehicle which can detect the current of an inductive load accurately and can drive the inductive load, when performing low side driving of the inductive load.SOLUTION: A storage section 6 prestores the relationship of the detection temperature of a thermistor 8 and the output voltage of a differential amplifier circuit (voltage amplification section) 3 for each on/off timing of an ignition switch IG. A control circuit 4 corrects the output voltage of the differential amplifier circuit, by substituting the detection temperature of the thermistor, detected during actual driving, for an approximation formula approximating a learning value stored. |
