PROBLEM TO BE SOLVED: To provide a vehicle speed sensor failure determination device which properly determines a failure of a vehicle speed sensor and can avoid imparting incongruity to a driver.SOLUTION: A vehicle speed sensor failure determination section 34 determines that a vehicle speed sensor 23 has a failure when a state has continued for a prescribed time in which an engine rotation number NE calculated by an engine rotation number calculation section 31 is within a prescribed range equal to or greater than a first value XNEL and equal to or smaller than a second value XNEH which is larger than the first value, a throttle opening TH calculated by a throttle opening calculation section 32 is equal to or greater than a determination value XTHL which is established on the basis of the engine rotation number NE, and a vehicle speed VSP calculated by a vehicle speed calculation section 33 is equal to or smaller than a prescribed value.
【課題】車速センサの故障を適切に判定し、運転者に違和感を与えることを抑制可能な車速センサ故障判定装置を提供する。【解決手段】、車速センサ故障判定部34が、エンジン回転数算出部31によって算出されたエンジン回転数NEが第1の値XNEL以上で第1の値より大きい第2の値XNEH以下である所定範囲内にあり、スロットル開度算出部32によって算出されたスロットル開度THがエンジン回転数NEに基づいて設定される判定値XTHL以上であり、かつ、車速算出部33によって算出された車速VSPが所定値以下である状態が、所定時間継続した場合に、車速センサ23が故障していると判定する。【選択図】図2
