identifies an effective range of a traffic regulation indicated by a traffic regulation mark; identifies a remaining amount, which is at least one of a remaining travel distance and a remaining travel time required from a vehicle position of the vehicle to an end point of the effective range; and controls the display device to display remaining amount information indicating the remaining amount, in addition to traffic regulation content information indicating a content of the traffic regulation in the effective range, in the display region when the vehicle enters into the effective range. ## Claims ### Claim 1 A vehicle display control device for a vehicle comprising: a display control unit that controls a display device for displaying information in a display region in front of a driver's seat of a vehicle; an effective range identification unit that identifies an effective range of a traffic regulation indicated by a traffic regulation mark, which is at least one of a traffic sign or a road marking on a travelling road of the vehicle; and a remaining amount identification unit that identifies a remaining amount, which is at least one of a remaining travel distance and a remaining travel time required from a vehicle position of the vehicle to an end point of the effective range, wherein: when the vehicle enters into the effective range, the display control unit controls the display device to display remaining amount information indicating the remaining amount identified by the remaining amount identification unit, in addition to traffic regulation content information indicating a content of the traffic regulation in the effective range, in the display region; the display region includes a plurality of display areas at different positions from each other; the display control unit switches the display region for displaying the remaining amount information according to a travelling situation of the vehicle with respect to the effective range; the display control unit controls to display the remaining amount information in one of the display areas for displaying an image that appears farther from a driver seated in the driver's seat when the vehicle enters into the effective range; and the display control unit successively switches the one of the display areas for displaying the remaining amount information to another one of the display areas for displaying the image that appears nearer from the driver seated in the driver's seat. ### Claim 2 (depends on 1) The vehicle display control device according to claim 1, wherein: the display region includes two display areas at different positions from each other; the display control unit controls to display the remaining amount information in the one of the display areas as a far position display area for displaying the image that appears farther from the driver seated in the driver's seat when the vehicle enters into the effective range; the display control unit successively switches the one of the display areas for displaying the remaining amount information to another one of the display areas as a near position display area for displaying the image that appears nearer from the driver seated in the driver's seat; and when the vehicle is located in a region in which a plurality of effective ranges indicated by a plurality of types of traffic regulation marks overlap with each other, and when each of the display areas that displays the remaining amount information corresponding to a respective type of the traffic regulation marks is the near position display area, the display control unit switches the one of the display areas, for displaying the remaining amount information corresponding to one of the types of traffic regulation marks having a low priority which is preliminarily set, to the far position display area. ### Claim 3 (depends on 2) The vehicle display control device according to claim 2, wherein: the priority is preliminarily set to be higher for the remaining amount information of which the remaining amount identified by the remaining amount identification unit is small. ### Claim 4 (depends on 2) The vehicle display control device according to claim 2, wherein: the priority is preliminarily set according to a selection by the driver received through a user interface. ### Claim 5 (depends on 2) The vehicle display control device according to claim 2, wherein: the priority is preliminarily set according to the types of the traffic regulation marks. ### Claim 6 (depends on 2) The vehicle display control device according to claim 2, wherein: the priority is preliminarily set according to the types of the traffic regulation marks and a traveling state of the vehicle. ### Claim 7 (depends on 2) The vehicle display control device according to claim 2, wherein: when the display control unit switches the one of the display areas, for displaying the remaining amount information corresponding to one of the types of traffic regulation marks having a low priority, from the near position display area to the far position display area, the display control unit controls to display the remaining amount information to be displayed in the far position display area in a display manner less conspicuous than an original display manner of the remaining amount information displayed in the far position distal display area when the vehicle enters into the effective range. ### Claim 8 (depends on 2) The vehicle display control device according to claim 2, wherein: when the display control unit switches the one of the display areas, for displaying the remaining amount information corresponding to one of the types of traffic regulation marks having a low priority, from the near position display area to the far position display area, and when the remaining amount information, of which the one of the display areas is switched to the far position display area, corresponds to the plurality of types of traffic regulation marks, the display control unit controls to display the remaining amount information for the plurality of types of traffic regulation marks be arranged from the near position display area in a descending order of the priority. ### Claim 9 (depends on 1) The vehicle display control device according to claim 1, wherein: the display device as a head-up display displays a virtual image of a display image visible for the driver by projecting the display image to one of a plurality of projection areas in front of the driver's seat of the vehicle; and each of the plurality of display areas is a display area of the virtual image corresponding to a respective projection area of the display device. ### Claim 10 (depends on 1) The vehicle display control device according to claim 1, wherein: each of the plurality of display areas is a display area for displaying information in a respective one of a plurality of display devices having different types. ### Claim 11 (depends on 1) A vehicle display unit for a vehicle comprising: a display device that displays information in a display region in front of a driver's seat of a vehicle; and the vehicle display control device according to claim 1. ### Claim 12 A vehicle display control device for a vehicle comprising: a processor, wherein: the processor is configured to: control a display device for displaying information in a display region in front of a driver's seat of a vehicle; identify an effective range of a traffic regulation indicated by a traffic regulation mark, which is at least one of a traffic sign or a road marking on a travelling road of the vehicle; and identify a remaining amount, which is at least one of a remaining travel distance and a remaining travel time required from a vehicle position of the vehicle to an end point of the effective range; when the vehicle enters into the effective range, the processor is configured to control the display device to display remaining amount information indicating the remaining amount, in addition to traffic regulation content information indicating a content of the traffic regulation in the effective range, in the display region; the processor is configured to control the display device to display the remaining amount information in one of a plurality of display areas for displaying an image of the display region that appears farther from a driver seated in the driver's seat when the vehicle enters into the effective range; and the processor is configured to switch the one of the plurality of display areas for displaying the remaining amount information to another one of the plurality of display areas for displaying the image that appears nearer from the driver seated in the driver's seat.
