Abstract: A vehicle surrounding display apparatus comprises a display control means for displaying images, each of which corresponding to each of a plurality of display modes on a display screen. The display control means, when at a first mode, generates a first bird's-eye view image of a vehicle and a first surrounding region thereof seen from a bird's-eye view to display this image in a first display area with a fixed size on the display screen and generates a first another image to display this image in a second display area with a fixed size on the display screen, and when at a second mode, generates a second bird's-eye view image of a vehicle and a second surrounding region thereof wider than the first surrounding region to display this image in the first display area and generates a second another image to display this image in the second display area.

Abstract: An electric power source control device includes an acquisition unit that acquires a charging/discharging current of a low-voltage battery, a detection unit that detects a predetermined operation executed with respect to a high-voltage battery, and a determining unit that determines presence/absence of an abnormality with respect to a connection state of the low-voltage battery, based on the charging/discharging current. When the predetermined operation is detected, the determining unit determines whether a state in which the charging/discharging current is no greater than a first threshold value continues for a first duration of time, controls an electric power converter when the state continues for the first duration of time, and further determines whether the state continues for a second duration of time longer than the first duration of time, and determines that the connection state of the low-voltage battery is abnormal when the state continues for the second duration of time.

Abstract: A relay drive control device is configured to control drive of a relay for connecting a battery mounted on a vehicle and an external power supply. The relay drive control device includes a controller configured to, when driving the relay, supply an output voltage of the battery to the relay after increasing the output voltage to a voltage value at which the relay is drivable.
