PROBLEM TO BE SOLVED: To obtain a detection apparatus by which the zero point of a vehicle state sensor can be detected with good accuracy. SOLUTION: An apparatus is provided with a straight-travelling state detection means M2 which detects the straight-travelling state of a vehicle, with a selection means M3 which selects detection data on a vehicle state sensor M1 in a prescribed vehicle-speed region when the straight-advance state of the vehicle is detected and with a computing means M4 which computes the zero-point correction value of the vehicle state sensor so as to detect a zero point on the basis of a prescribed relationship between the selected detection data and a vehicle speed at its detection. Thereby, the characteristic model error and the nonlinearity of a tire and the deteciton data in which the disturbance of a road surface is large are excluded, and the zero point can be detected with high accuracy. |
