Claims

[Claims for Utility Model Registration] (1) In order to control in-vehicle equipment that moves the opening/closing body to a desired position using a driving means, the position of the opening/closing body can be stored and the stored position of the opening/closing body can be adjusted. A control circuit for in-vehicle equipment, comprising a programmable control means for controlling the drive means accordingly, and a monitoring means for monitoring the operating state of the control means and resetting the program of the control means when there is an abnormality, The monitoring means and the control means are supplied with power separately from each other, power switch means capable of selectively supplying power to the monitoring means, and means for detecting on/off of an ignition key switch of the vehicle. A control circuit for in-vehicle equipment, comprising: supplying power to the monitoring means only when an ignition key switch of the vehicle is on. (2) The monitoring means includes means for monitoring the control means based on a clock signal generated by a clock signal generation means that can be activated/stopped by the control means, and when power is supplied to the control means, the The control means has a reset means for resetting the program of the control means to an initial state, and a clear means for erasing the contents stored in the control means after power is supplied to the control means and the program is reset by the reset means. The in-vehicle device according to claim 1, wherein the control means stops the clock signal generation means when the ignition key switch is off after the program is reset by the reset means. Control circuit for equipment.
