Summary: | To provide a control device for vehicle capable of suppressing erroneous determination being performed due to the increased outdoor temperature even when a fuel pressure sensor is normal.SOLUTION: A control device 400 includes: a soak timer 101 for timing lapsed time after a main switch 120 of a vehicle 10 is turned OFF; a nonvolatile memory 102; and a determination part 301 for starting when the lapsed time has reached prescribed time while the main switch 120 is turned OFF and acquiring a fuel pressure by a fuel pressure sensor, and for performing rationality check to determine whether or not the acquired fuel pressure is within a normal range. In a control device 400, a determination part 301 executes the rationality check on condition that the execution condition is established, and when the index value of the outdoor temperature acquired when the lapsed time has reached the prescribed time and started is higher than the index value of the outdoor temperature stored in the nonvolatile memory 102, the execution condition is made to be strict.SELECTED DRAWING: Figure 1
【課題】燃料圧力センサが正常であるにも拘わらず、車外温度が高くなったことによって誤った判定を行ってしまうことを抑制できる車両の制御装置を提供する。【解決手段】制御装置400は、車両10のメインスイッチ120がOFFにされてからの経過時間を計時するソークタイマ101と、不揮発性メモリ102と、メインスイッチ120がOFFになっている間に経過時間が規定時間に到達したときに起動して燃料圧力センサによって燃料圧力を取得し、取得した燃料圧力が正常範囲内に収まっているか否かを判定するラショナリティチェックを行う判定部301と、を備えている。制御装置400では、判定部301が、実行条件が成立していることを条件にラショナリティチェックを実行し、不揮発性メモリ102に記憶した車外温度の指標値よりも経過時間が規定時間に到達して起動したときに取得した車外温度の指標値が高いときに前記実行条件を厳しくする。【選択図】図1 |
