Abstract

The system displays an appropriate confirmation screen depending on when the activation process is performed. [Solution] The OTA master 11 installed in the vehicle 10 controls the display of information regarding software updates for in-vehicle equipment on the HMI 18. The OTA master 11 displays a confirmation image on the HMI 18 before starting the activation process to activate the update software installed on the in-vehicle equipment. The power mode of the vehicle 10 switches between a driving power mode and a parking power mode depending on the ON / ON operation of the power switch 24. The OTA master 11 displays different confirmation images on the HMI 18 depending on whether the software update is performed in a first update procedure, which performs the activation process in response to switching the power switch 24 from ON to OFF, or in a second update procedure, which performs the activation process in response to switching the power switch 24 from OFF to ON.
