Abstract

A vehicle display control device, which controls a display of sensor information on a display unit corresponding to each external sensors, includes an opening detection unit, an image storage unit, and an opening control unit. The vehicle is equipped with the display unit and the external sensors detecting outside obstacles. The opening detection unit detects an opening command made by a user to the vehicle. The image storage unit stores a vehicle image indicating the vehicle and area images indicating detection areas of the sensors. The obstacle is detectable within the detection areas. In response to a detection of the opening command by the opening detection unit, the opening control unit reads the vehicle image and each area image from the image storage unit, and displays the readout images on the display unit as the sensor information during an opening period.
