Title:
POWER SUPPLY CONTROL SYSTEM, AND PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/220055
Kind Code:
A1
Abstract:
A first ECU (control device) (11) switches a power supply switch (F1) on or off to control power supply through the power supply switch (F1). A second ECU (switching device) (12) switches a power source switch (14) on or off. In the first ECU (11), a processing unit executes non-power supply control processing, different from processing relating to control of the power supply via the power supply switch (F1). After detection of an energization failure, whereby a current flows via the power supply switch (F1) despite the second ECU (12) instructing the power supply switch (F1) to turn off, the second ECU (12) repeatedly switches the power supply switch (14) on and off alternately.
