Abstract: A vehicle display control device includes a memory and a processor coupled to the memory. The processor is configured to: recognize a traffic regulation mark provided on a traveling path of a car, the traffic regulation mark indicating traffic regulation; specify a valid regulation range used as a valid range of regulation indicated by the traffic regulation mark based on the recognized traffic regulation mark; and control a display device mounted on the car to display regulations information on a display area, the regulations information including contents of regulation indicated by the recognized traffic regulation mark. The processor is configured to switch displaying the regulations information into another upon satisfying a predetermined condition in a case where the valid regulation range is not specified.

Abstract: A vehicle display control device provided in a vehicle is disclosed. The apparatus includes processing circuitry. The processing circuitry recognizes a traffic regulation mark indicating a traffic regulation provided on a traveling route of the vehicle. The processing circuitry controls a display device to display first content information and second content information in a display area in front of a driver's seat of the vehicle. The first content information indicates content of a regulation in an effective range indicated by the traffic regulation mark in a case where the vehicle enters the effective range of the regulation. The second content information indicates content other than the first content information. The processing circuitry controls display of the first content information and the second content information in the display area on the basis of priorities set for the first content information and the second content information.

Abstract: The time required for transition from an on-state to a suspend state is reduced. An electronic apparatus includes: a memory and a memory; a current control unit that performs a control to shut off supply of current to the memory; and a memory management unit that allocates a memory region in either the memory or the memory based on preference information indicating a memory region that needs to be preferentially allocated in the memory.

Abstract: A straddle vehicle is capable of discharging high-temperature outdoor air having passed through a radiator with high efficiency. A motorcycle 1 includes a radiator, a fan, and a fan shroud. The radiator lowers the temperature of a coolant by heat exchange between outdoor air and the coolant. The fan suctions outdoor air, to make the outdoor air hit the radiator arranged upstream in an outdoor air flow direction. The fan shroud covers at least part of the fan, and discharges high-temperature outdoor air, which is outdoor air suctioned by the fan and having passed through the radiator, to outside. The fan shroud has a discharge opening and an air guide. The discharge opening allows the high-temperature outdoor air to be discharged outside. The air guide guides the high-temperature outdoor air such that it is discharged through the discharge opening in a direction including a laterally outward component.
