Abstract

An electronic control device includes a first pull-up resistor connected between a power supply and a switch, a series circuit of a transistor and a second pull-up resistor with a resistance value lower than that of the first pull-up resistor, connected in parallel with the first pull-up resistor, and a microcomputer, an output port of which is connected to a base terminal of the transistor and which controls a turning on and off of the transistor using a signal output from the output port. A connection point of the switch, the first pull-up resistor, and the second pull-up resistor is connected to a first analog measurement port of the microcomputer, a power supply is connected to a second analog measurement port of the microcomputer, and current flowing into the switch is detected using a value of voltage input into the first analog measurement port.
