PROBLEM TO BE SOLVED: To make deviation of a characteristic value acquired by estimation from an actual value small in a case where the characteristic value to be a value related to the relationship between voltage and current in a coil is acquired by estimation, in an electromagnetic valve control device.SOLUTION: A temperature correction coefficient KTR of a pressure reduction linear valve is estimated based on temperature (S25), and a temperature correction coefficient KTA of a pressure increase linear valve is acquired by actually supplying current (S11, S12). When the estimation value of the temperature correction coefficient KTR of the pressure reduction linear valve is smaller than the actual value of the temperature correction coefficient KTA of the pressure increase linear valve (YES in determination of S26), the estimation value is corrected to the same value as the actual value (S28).

    【課題】電磁弁制御装置において、コイルについての電圧と電流との関係に関連する値である特性値が推定によって取得される場合において、推定によって取得された特性値の実際値からの乖離を小さくする。【解決手段】減圧リニア弁の温度補正係数KTRは温度に基づいて推定され(S25)、増圧リニア弁の温度補正係数KTAは実際に電流を供給することにより取得される(S11,S12)。減圧リニア弁の温度補正係数KTRの推定値が増圧リニア弁の温度補正係数KTAの実際値より小さい場合(S26の判定がYES)には、推定値が実際値と同じ値に補正される(S28)。【選択図】図9
