Title:
METHOD AND DEVICE FOR CONTROLLING VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/013962
Kind Code:
A1
Abstract:
A vehicle having an automated driving function comprises an alternator (2), a stator motor (5), a load group A (21) including one of two automated driving electrical loads forming a redundant system, a load B group (22) including the other load, a lead acid battery (6), and a backup lithium ion battery (7). During normal driving a circuit breaker switch (13) and a LiB relay (10) are ON. When the vehicle is restarted after idling stop control, the circuit breaker switch (13) is OFF, and electric power is supplied from the lead acid battery 6 to the stator motor (5). For a predetermined period after the restart, priority charging of the lead acid battery (6) is performed while the circuit breaker switch (13) remains OFF, after which the circuit breaker switch (13) is switched to ON and the lithium ion battery (7) is also charged. Even if the idling stop control and an accompanying restart are repeated, the state of charge of a first power storage device does not decrease excessively, and electric power supply to the automated driving electric loads can be reliably continued.
