Abstract
A low power consumption type automobile-mounted controller capable of switching so as not to continue power consumption of the automobile-mounted power source when the automobile has not been used over a long term. The low power consumption type automobile-mounted controller comprises: a microcontroller unit having a power supply port, a voltage detection port, a control port, a communication port, and an input port; a first power supply path connected to the automobile-mounted power source through a change-over switch for turning ON/OFF the power supply port; a second power supply path for connecting the power supply port to the automobile-mounted power source through a controllable switch; and power open/close command means for turning ON/OFF the controllable switch in response to a power close command signal or a power open command signal, and operates in such a manner that on receipt of the power open command signal while the first power supply path is intercepted by turning OFF the change-over switch, the power open/close command means turns OFF the controllable switch to intercept the second power supply path.
