摘要： A multicylinder engine includes: combustion chambers; fuel injection valves corresponding to the individual combustion chambers; an exhaust control catalyst; an upstream-side air/fuel ratio sensor disposed upstream of the exhaust control catalyst; and a downstream-side A/F sensor disposed downstream of the catalyst. A first abnormality determination-purpose rich A/F control of controlling the A/F of the mixture formed in each combustion chamber to an A/F richer than stoichiometric is executed when it needs to be determined whether the downstream-side A/F sensor is abnormal. An inter-cylinder A/F imbalance determination of estimating the A/F of the mixture in each combustion chamber based on the output of the upstream-side A/F sensor is executed when the first abnormality determination-purpose rich A/F control is being executed, and it is determined whether there is a difference between the estimated A/Fs of the mixtures.

摘要： According to one embodiment, there is provided a vehicle controller including: a sudden change judgment section that judges whether a change rate of a detected yaw rate is equal to or more than a predetermined value; a normative yaw rate calculator that calculates a normative yaw rate based on a steering angle amount; and a correction section that performs a correction for making a detected lateral acceleration close to a value to be detected at a gravity center of a vehicle, by using: the detected yaw rate when the sudden change judgment section judges that the change rate of the detected yaw rate is less than the predetermined value; and the normative yaw rate instead of the detected yaw rate when the sudden change judgment section judges that the change rate of the detected yaw rate is equal to or more than the predetermined value.
