Title:
ALTERNATOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/142915
Kind Code:
A1
Abstract:
Provided is an alternator control device capable of effectively preventing the occurrence of trouble attributed to rapid electric current consumption in a situation where the output voltage of an alternator is reduced. An alternator control device (1) comprises: a battery state determination unit (12) which determines whether or not the state of a battery (91) is a predetermined normal state; a vehicle speed determination unit (14) which determines whether or not the speed of a vehicle is in a predetermined low speed range; a position determination unit (16) which determines whether or not the position of the vehicle satisfies a predetermined position condition; and an output voltage instruction unit (18) which provides an instruction regarding the output voltage of an alternator (93). If the battery state determination unit (12) determines that the state of the battery (91) is not the predetermined normal state, if the vehicle speed determination unit (14) determines that the speed of the vehicle is in the predetermined low speed range, and if the position determination unit (16) determines that the position of the vehicle satisfies the position condition, the output voltage instruction unit (18) provides an instruction to set the output voltage of the alternator (93) higher than a reference voltage.
