Document Type and Number:
Japanese Patent JP2022054892
Kind Code:
A
Abstract:
To suppress a motor from being wrongly activated in executing reproduction.SOLUTION: A vehicle comprises: a high voltage-system circuit which includes a high-voltage battery and an inverter which converts DC power supplied from the high-voltage battery to AC power and outputs the power to a motor as a travelling-driving source; a low-voltage system circuit which includes a low-voltage battery which is lower in output voltage than the high-voltage battery and a renewing part that executes renewal of a program related to a device to be renewed, using power supplied from the low-voltage battery or the high-voltage battery; a DC-DC converter, connected to a space between the high-voltage system circuit and the low-voltage system circuit, which can step down output power from the high-voltage battery and supply the power to the low-voltage system circuit; and a control part that restricts operation of the inverter, at a timing when renewal of the program is started, when the renewing part starts to renew the program related to the device to be renewed.SELECTED DRAWING: Figure 6
