Abstract
A sensor output correction system is provided which is capable of minimizing a risk that a correction value for use in zero-point correction differs from an actual deviation of a zero-point. An ECU includes a travel road information acquisition portion which obtains a curvature of a travel road on which a system-mounted vehicle is traveling and a vehicle information acquisition portion which obtains a detected value of a yaw rate sensor. The ECU determines whether the system-mounted vehicle is traveling on a straight path or not based on the curvature derived by the travel road information acquisition portion. The ECU determines a value (i.e., a zero-point equivalent value) which corresponds to a deviation of a current zero point of the yaw rate sensor based on detected values of the yaw rate sensor sampled while the system-mounted vehicle is moving on the straight path. The ECU determines a correction value which is subtracted from the detected value using the zero-point equivalent value.
