    Abstract: In some embodiments, a vehicle is provided having improved fuel economy by using gradual engine speed control. Once a governor activation threshold is crossed, a dynamic engine speed limit that gradually increases over time is implemented. In some embodiments, if the engine speed does not continue to rise over time, increases in the dynamic engine speed limit may be paused. In some embodiments, if the engine speed increases at too great of a rate for too long of a time, the dynamic engine speed limit may be reset. In some embodiments, increasing, pausing, and/or resetting the dynamic engine speed limit allows gradual acceleration while also avoiding torque lock.

  • Patent number: 9976765
    Abstract: A method controls an operation of an air-conditioning system generating airflow in a conditioned environment. The method updates a model of airflow dynamics connecting values of flow and temperature of air conditioned during the operation of the air-conditioning system. The model is updated interactively iteratively to reduce an error between values of the airflow determined according to the model and values of the airflow measured during the operation. Next, the method models the airflow using the updated model and controls the operation of the air-conditioning system using the model.

  • Patent number: 9815457
    Abstract: In the case where a throttle valve has a sticking abnormality, a hybrid vehicle performs failsafe operation (limp home mode) with fixing the throttle valve to an opener position (S100) and sets a restoration diagnosis cooling water temperature T1 such as to decrease with a decrease in state of charge SOC of a battery (S120). When cooling water temperature Tw of the engine becomes equal to or higher than the restoration diagnosis cooling water temperature T1, the hybrid vehicle performs sticking restoration diagnosis to determine whether the throttle valve is restored from the sticking abnormality (S150). This allows for earlier diagnosis of whether the throttle valve is restored from the sticking abnormality at the lower state of charge SOC of the battery and enables the hybrid vehicle to return to normal operation at an earlier time. As a result, this ensures the more adequate sticking restoration diagnosis.

  • Patent number: 9804059
    Abstract: Based on entry/exit pressures of a compressor detected by atmospheric/boost pressure sensors, a pressure ratio of compressor is calculated. Based on mass flow rate and entry temperature of intake air detected by intake air flow-rate/temperature sensors and entry pressure, a volumetric flow rate of intake air is calculated in environmental condition at a detection time using gas state equation, and is corrected into a volumetric flow rate under standard environmental condition thorough multiplication by a corrective coefficient based on entry temperature of intake air. Based on the corrected value and the calculated pressure ratio, a rotational frequency of compressor under standard environmental condition is read out in light of operating characteristic diagram for the compressor.
