PROBLEM TO BE SOLVED: To provide an other vehicle position display device which, while reducing a processing load due to map matching, is capable of displaying the position of another vehicle with reduced discomfort that may be felt by a viewer.SOLUTION: The other vehicle position display device includes: a map matching unit 168 which, when another vehicle position is within a peripheral range 30 of the user vehicle that is set to a narrower range than a map display range 40, performs map-matching on the other vehicle position, but when the other vehicle position is outside the peripheral range 30, does not perform map-matching on the other vehicle position; and a map display processing unit 169 for displaying, on a display unit 14, a road map in which the scale of the outside of the peripheral range 30 is smaller than the scale of the peripheral range 30, and displaying, for another vehicle whose other vehicle position is within the peripheral range 30, another vehicle diagram 60 at the other vehicle position after map-matching is performed, and, for another vehicle whose other vehicle position is outside the peripheral range 30, another vehicle diagram 60 at the other vehicle position acquired by another vehicle position acquisition unit 164.

    【課題】マップマッチングによる処理負荷を低減しつつ、他車両の位置を、見る者に与える違和感を少なくして表示することができる他車両位置表示装置を提供する。【解決手段】他車両位置が、地図表示範囲40よりも狭い範囲に設定された自車両の周辺範囲30内である場合、その他車両位置に対してマップマッチングを行うが、他車両位置が周辺範囲30の外である場合には、その他車両位置に対してはマップマッチングを行わないマップマッチング部168と、表示部14に、周辺範囲30よりも外側の縮尺が周辺範囲30の縮尺よりも小さい道路地図を表示するとともに、他車両位置が周辺範囲30内である他車両については、マップマッチングを行った後の他車両位置に他車両図形60を表示し、他車両位置が周辺範囲30外である他車両については、他車両位置取得部164が取得した他車両位置に他車両図形60を表示する地図表示処理部169とを備える。【選択図】図2
