5. Notification devices (11-14) that notify update information regarding software updates when the software of the electronic control unit to be updated is updated by update software obtained from a distribution device, A vehicle system (2) comprising an update information notification device (7) that notifies the update information from the notification device, The update information notification device is, The update information acquisition unit (16a) acquires the aforementioned update information, A crew status identification unit (16b) that identifies the crew status, which indicates the condition of the crew, A vehicle condition identification unit (16c) that identifies the vehicle condition, which indicates the state of the vehicle, An operation input identification unit (16d) that identifies the operator's operation input, The system includes a notification control unit (16e) that determines the notification method for the update information and causes the notification device to notify the update information according to the determined notification method, The notification control unit is a vehicle system that, when the vehicle power is turned off as determined by the vehicle status determination unit and the occupant status determination unit is determined to be absent from the vehicle, and an operation input indicating a request for notification of the update information is determined by the operation input determination unit, determines the notification method of the update information more simply than when the occupant status determination unit is determined to be absent from the vehicle.
6. The control unit (16) of the update information notification device (7), which notifies update information regarding the software update when the software of the electronic control device to be updated is updated by update software obtained from the distribution device, The procedure for obtaining the aforementioned update information, A procedure for identifying the crew status, which indicates the condition of the crew, A procedure for identifying the vehicle's condition, which indicates the state of the vehicle, Operation input identification procedure to identify crew member operation input, When the vehicle power is turned off according to the vehicle status identification procedure and the occupant status identification procedure is determined, and an operation input indicating a request for notification of the update information is determined according to the operation input identification procedure, a notification manner determination procedure for determining the notification manner of the update information is determined in a simpler manner than when the occupant status identification procedure is determined to determine that an occupant is present in the vehicle; An update information notification program that executes a notification control procedure to cause the notification device to notify the update information in accordance with the notification manner determined by the notification manner determination procedure.

Description

This invention relates to an update information notification device, a vehicle system, and an update information notification program. Conventionally, technologies have been provided for updating the software of in-vehicle electronic control units (hereinafter referred to as ECUs (Electronic Control Units)) for purposes such as improving functionality or fixing bugs. In this method, a server distributes the update software to a software update device, which then transmits the update software to the target ECU, thereby updating the ECU's software. The software update process involves a phase of campaign notification recommending the update to the driver, a download phase where the software update device obtains the update software from the server, an installation phase where the target ECU writes the update software to its storage, and an activation phase where the target ECU activates the update software. In this case, update information regarding the software update is notified to the driver, for example, by displaying it on an in-vehicle display device or a mobile device. For example, Patent Document 1 discloses a method for notifying drivers of update information regarding software updates, in which the notification to the driver differs based on the characteristics of the update software.

The following describes one embodiment with reference to the drawings. The software update system 1 is configured to enable data communication between the vehicle system 2 installed in the vehicle and a server 3 (corresponding to a distribution device) functioning as an OTA (Over The Air) center via a communication network 4. The vehicle system 2 is configured to enable data communication between a software update device (hereinafter referred to as a Central Gateway (CGW)) 5 functioning as an OTA master, a number of ECUs 6, and an HMI (Human Machine Interface) control unit (hereinafter referred to as an HCU (HMI Control Unit)) 7 (corresponding to an update information notification device) via an in-vehicle network 8. The in-vehicle network 8 is, for example, CAN (Controller Area Network) (registered trademark). The in-vehicle network 8 may also be FLEXRAY (registered trademark), CXPI (Clock Extension Peripheral Interface) (registered trademark), Ethernet (registered trademark), etc. In this embodiment, a configuration in which four ECUs 6 are connected to the in-vehicle network 8 is illustrated, but the number of ECUs 6 connected to the in-vehicle network 8 is arbitrary. Furthermore, the number of in-vehicle networks 8 is also arbitrary. ECU6 includes devices that control the drive system, ADAS (Advanced Driving Assistant System) systems, and multimedia systems, and may become eligible for software updates due to software modifications or functional improvements. Software includes not only the so-called program that instructs the computer on the processing procedures for operation, but also files, data, libraries, etc., that are referenced when the program is executed.
