Title: ELECTRONIC CONTROL DEVICE
Abstract:
The purpose of the present invention is to propose an electronic control system such that failure in a main relay can be mitigated and an increase in cost can be minimized. The present invention provides an electronic control device in which a current from a battery is input to an input terminal of a power supply IC through a contact point of a main relay and a UB line connected to the contact point, wherein the electronic control device is equipped with: a capacitor which is connected to the UB line at one end and is grounded at the other end; and an inrush current prevention section which is connected at one end to the UB line at a position located upstream of the capacitor and is connected to the battery at the other end. The inrush current prevention section charges the capacitor by receiving the input current from the battery through the other end thereof and outputting the current from the one end before the main relay is turned on, and stops recharging the capacitor by stopping the input of the current from the battery when a predetermined condition is met.
