Abstract
An over-the-air (OTA) update apparatus for a vehicle may include an update management device for generating mode information about an OTA update of the vehicle, an update execution device for performing OTA updates of one or more controllers included in the vehicle based on the generated mode information, and a battery charging control device for controlling charging of a low-voltage battery of the vehicle based on the generated mode information.
Claims18
An over-the-air (OTA) update apparatus for a vehicle, the OTA update apparatus comprising:
- at least one processor operably connected to a wireless communication network for receiving an OTA update, and operably connected to a battery including a low-voltage battery of the vehicle, the at least one processor operable to:
- generate mode information, by an update management device, about the OTA update of the vehicle;
- perform OTA updates, by an update execution device, of one or more controllers included in the vehicle based on the generated mode information, and perform OTA update rollback when the OTA updates are not completed;
- control charging, by a battery charging control device, of the low-voltage battery of the vehicle based on the generated mode information;
- and
- generate, by the update management device, first mode information indicating that the OTA update of the vehicle is performed, when a state of charge (SOC) value of a high-voltage battery is greater than or equal to a preset first value, an SOC value of the low-voltage battery is greater than or equal to a preset second value, and the vehicle is powered off, wherein the first value is preset based on a value obtained by adding a management reference lower limit SOC of the high-voltage battery and a maximum SOC value used to charge the low-voltage battery.
An over-the-air (OTA) update method for a vehicle, the method comprising:
- generating, by an update management device, mode information about an OTA update of the vehicle;
- performing, by an update execution device, OTA updates of one or more controllers included in the vehicle based on the generated mode information and OTA update rollback when the OTA updates are not completed;
- and
- controlling, by a battery charging control device, charging of a low-voltage battery of the vehicle based on the generated mode information,
- wherein generating the mode information includes:
- generating first mode information indicating that the OTA update of the vehicle is performed, when a state of charge (SOC) value of a high-voltage battery is greater than or equal to a preset first value, an SOC value of the low-voltage battery is greater than or equal to a preset second value, and the vehicle is powered off, wherein the first value is preset based on a value obtained by adding a management reference lower limit SOC of the high-voltage battery and a maximum SOC value used to charge the low-voltage battery.
