Abstract
A vehicular software update apparatus is used to a vehicle to update software stored in an electronic control unit mounted on the vehicle. The vehicular software update apparatus includes a low power communication device configured to perform a wide area wireless communication with a low power consumption. The low power communication device is operated in an update confirmation state including a state where neither power generation in the vehicle nor power supplying to the vehicle is performed, and is caused to download software update information which is information necessary to update the software, when the software update information, is provided by the server.
Claims12
A method, comprising:
- receiving, by a vehicle from a server, software update information in a first state where neither power generation in the vehicle nor power supplying to the vehicle is performed;
- downloading, by the vehicle based on the software update information, a software update program for updating a software stored in an electronic control unit mounted on the vehicle, wherein the downloading is performed by the vehicle in a second state where power generation in the vehicle, or power supply to the vehicle, or both the power generation in the vehicle and the power supply to the vehicle is performed.
An apparatus, comprising:
- at least one processor;
- and
- a memory coupled to the at least one processor and storing programming instructions for execution by the at least one processor, the programming instructions cause the at least one processor to:
- receive, from a server, software update information used to update software of a vehicle, wherein the vehicle receives the software update information in a first state where neither power generation in the vehicle nor power supplying to the vehicle is performed;
- and
- download a software update program for updating the software, based on the software update information, in a second state where power generation in the vehicle, or power supply to the vehicle, or both the power generation in the vehicle and the power supply to the vehicle is performed.
A non-transitory computer-readable storage medium comprising instructions that, when executed by a processor, cause a vehicle to:
- receive, from a server, software update information used to update software of the vehicle, wherein the software update information is received in a first state where neither power generation in the vehicle nor power supplying to the vehicle is performed;
- and
- download a software update program for updating the software, based on the software update information, wherein the downloading is performed by the vehicle in a second state where power generation in the vehicle, or power supply to the vehicle, or both the power generation in the vehicle and the power supply to the vehicle is performed.
