VEHICLE-MOUNTED APPARATUS, PROGRAM, AND INFORMATION PROCESSING METHOD

A vehicle-mounted apparatus is mounted in a vehicle and is connected to a plurality of actuators. The vehicle-mounted apparatus includes: a control unit for generating control signals for controlling the actuators; an output processing unit for outputting the control signals, which have been generated by the control unit, via signal pins to which the plurality of actuators are connected, and at least one internal pin that connects the control unit and the output processing unit and transmits the control signals, wherein the internal pins are fewer in number than the signal pins.
