Abstract

The present invention provides a vehicle control device, a vehicle control method, and a storage medium capable of more appropriately performing update of software. A vehicle control device includes acontroller with embedded software which controls at least some of devices mounted in the vehicle, a communicator configured to communicate with an external device, an update controller which updatesthe software embedded in the controller according to communication with the external device by the communicator, a power supply configured to supply power to the controller, and a vehicle state predictor configured to predict a state of the vehicle, in which the update controller interrupts an update of the software when the vehicle state predictor predicts that a connection between the power supply and the controller is in a disconnected state during the update of the software.

Description

technical field [0001] The invention relates to a vehicle control device, a vehicle control method and a storage medium. Background technique [0002] Conventionally, there is known an update device for updating software installed in a control unit for controlling equipment mounted on a vehicle (for example, refer to Japanese Patent No. 6216730). Patent Document 1 discloses a technique for performing control by communicating with a server by wireless communication, receiving update data from the server for each of a plurality of control units, and applying the update data to the control unit. The identification information identified by the application method is used, and the update data is applied to each of the plurality of control units based on the received identification information. [0003] However, in the conventional technology, when an unexpected power failure occurs in the vehicle, power cannot be supplied to the control unit, and the update of the software is in...
