Title:
ON-BOARD CONTROL DEVICE, AND METHOD FOR CONTROLLING ON-BOARD CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/270021
Kind Code:
A1
Abstract:
Provided is an on-board control device which controls the driving of multiple loads, wherein the on-board control device is highly reliable and capable of suppressing heat generation caused by a ripple current in an electronic component which constitutes the on-board control device. The present invention is characterized by comprising: a plurality of load driving circuits; a microcontroller that transmits control signals to the plurality of load driving circuits; a determination unit that determines whether the OFF timings of the control signals for the plurality of load driving circuits match each other; a time changing unit that changes, on the basis of the determination result of the determination unit, the OFF timings so that the OFF timings do not match each other; a control unit that sets load driving information from a load driving state, and that corrects the set load driving information on the basis of the change result of the time changing unit; and a waveform generation unit that generates, on the basis of the load driving information corrected by the control unit, control signals for the plurality of load driving circuits.
