PURPOSE: To easily detect a failure in a shift switch by providing an abnormality determination means for comparing a shift state estimated by a shift state estimated by a shift state estimation means with the position of a shift lever detected by a shift lever position detection means to determine whether or not there is a fault in the shift lever position detection means.
CONSTITUTION: A operation state detection means for detecting the operation state of an internal combustion engine and a shift state estimation means for estimating the shift state of a transmission from information detected by the operation state detection means. An abnormality determination means 10 compares the shift state estimated by the shift state estimation means 10 with the position of a shift lever detected by the shift lever position detection means 20 to determine whether or not there is a fault in the shift lever position detection means 20.
