Abstract: In a vehicle in which a traffic congestion autonomous driving operation and a driver required driving operation are executable, a display relating to a driving operation exchange from the traffic congestion autonomous driving operation to the driver required driving operation is performed when a switching from the traffic congestion autonomous driving operation to the driver required driving operation is requested, a situation of the vehicle is specified such that the switching from the traffic congestion autonomous driving operation to the driver required driving operation is requested, and at least one of a timing of the display and a content of the display relating to the driving operation exchange is changed according to the situation.

Abstract: A state identification unit identifies an automated driving related state, which is at least one of a traveling state of a vehicle related to an automated driving and a state of a driver of the vehicle. A passenger display control unit controls display on a second display provided to the vehicle and different from a first display exclusive for the driver. The second display is visible to a passenger of the vehicle other than the driver. A passenger request acquisition unit acquires a request from the passenger. The passenger display control unit causes the second display to display a passenger side graphic that indicates the automated driving related state, which is identified by the state identification unit, using at least one of a text and an image.

Abstract: According to one embodiment, a memory system includes a nonvolatile semiconductor storage device, a first storage module, a second storage module, a controller, a random number generator, and a randomizing module. The first storage module stores a plurality of management data. The second storage module stores seed data. The controller issues a first command to designate one of the management data, and issues a second command to command writing in or reading from the storage device. The random number generator generates random number data, by shuffling the seed data, based on the management data that is designated by the first command. The randomizing module randomizes written data or read data, based on the random number data.
