Document Type and Number:
Japanese Patent JP7287361
Kind Code:
B2
Abstract:
When software of a first electronic control unit that controls charging of an auxiliary machinery battery from a power supply by controlling a charging device is rewritten, an onboard system is configured so that charging of the auxiliary machine battery from the power supply is controlled by one or more electronic control units different from the first electronic control unit. Accordingly, even when the software of the first electronic control unit that controls the charging of the auxiliary machinery battery is rewritten, the auxiliary machinery battery can be charged by one or more electronic control units different from the first electronic control unit when the software is rewritten, and the power for rewriting the software of the first electronic control unit can be secured. This can ensure power to rewrite the software of the first electronic control unit.
