Abstract
Provided is a highly reliable in-vehicle control device that controls driving of a plurality of loads, the in-vehicle control device being capable of suppressing heat generation caused by a ripple current of an electronic component constituting the in-vehicle control device. The in-vehicle control device includes: a plurality of load drive circuits; a microcontroller that transmits control signals to the plurality of load drive circuits; a determination unit that determines whether OFF timings of the control signals transmitted to the plurality of load drive circuits, respectively, match; a time change unit that changes the OFF timings based on a determination result of the determination unit, so that the OFF timings do not match; a control unit that sets load drive information from drive states of loads and corrects the set load drive information based on a change result of the time change unit; and a waveform generation unit that generates control signals to be transmitted to the plurality of load drive circuits based on the load drive information corrected by the control unit.
