    Abstract: A failure determination system for a vehicle speed detection device, which, in a case where only one vehicle speed detection device is used, can always accurately perform failure determination of the device, and ensure a high marketability, while avoiding increases in manufacturing costs and product prices of the system. An ECU calculates an engine speed, calculates a detected vehicle speed based on a detection signal from a vehicle speed sensor, calculates an estimated total transmission gear ratio indicative of correlation between the detected vehicle speed and the engine speed, stores the estimated total transmission gear ratio, calculates a reference vehicle speed using a value of the estimated total transmission gear ratio, calculated predetermined times earlier, and the engine speed, and determines a failure of the sensor using a for-use-in-monitoring vehicle speed error which indicates an error between the reference vehicle speed and the detected vehicle speed.

  • Patent number: 9657673
    Abstract: The objective of the present invention is to provide an exhaust purification system that is capable of purifying exhaust gas during both lean and stoichiometric driving. The exhaust purification system is equipped with: a feedback-use identifier, which identifies parameter values such that the error between the output value from a LAF sensor and the estimated value for the LAF sensor output as obtained from a model equation is minimized; and a stoichiometric driving mode controller. The controller performs feedback control and thereby determines the fuel injection amount such that in the stoichiometric driving mode the equivalence ratio value as calculated from the parameters reaches a target value which is set such that a three-way purification reaction occurs in an under-engine catalyst. The identifier identifies the model parameters before feedback control is initiated by the controller.
