ABNORMALITY DETECTION DEVICE AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/162862
Kind Code:
A1
Abstract:
An abnormality detection device (30) comprises a booster circuit (31), internal power supplies (41, 42), components (15, 45, 47) that use boosted power supply, and a control unit (50). The booster circuit (31) boosts electric power from a battery (7). The internal power supplies (41, 42) supply the electric power boosted by the booster circuit (31). The components (15, 45, 47) that use boosted power supply operate using the electric power supplied from the internal power supplies (41, 42). The control unit (50) has a drive signal generation unit (51) and an abnormality determination unit (55). The drive signal generation unit (51) generates a booster circuit drive signal for driving the booster circuit (31). The abnormality determination unit (55) determines an abnormality related to the components that use boosted power supply. The abnormality determination unit (55) performs control to disable the abnormality determination related to the components (15, 45, 47) that use boosted power supply when the driving of the booster circuit (31) is stopped by turning off the booster circuit drive signal.
