摘要： Energy management techniques for heating or cooling a surface of a component of a vehicle comprise determining a heating lag time indicative of a lag time for a surface element of the vehicle component to heat to a first target temperature in response to a power on-off or power off-on modulation of a heat transfer component, determining a cooling lag time indicative of a lag time for the surface element to cool to a second target temperature in response to a power on-off or power off-on modulation of the heat transfer component, and controlling power-on and power-off times of the heat transfer component based on the determined heating and cooling lag times so as to not require a temperature sensor for feedback-based temperature control.

摘要： A method for determining an event-based hydraulic control delay in a multi-displacement system for an internal combustion engine, with which to adjust the triggering a solenoid in hydraulic communication with a hydraulically-deactivatable valve train component, includes retrieving either a first mapped value representative of a time-based hydraulic deactivation delay, or a second mapped value representative of a time-based hydraulic reactivation delay, based on a current engine speed and a current oil temperature, preferably using different lookup tables for each of the first and second mapped values. The method further includes determining a current time period between generated crankshaft position pulses, and dividing either the first value or the second by the first time period to obtain either an event-based hydraulic deactivation delay or an event-based hydraulic reactivation delay. The event-based delays are thereafter used to synchronize the timing of solenoid operation when deactivating or reactivating given engine cylinders.

摘要： A process for enabling cylinder deactivation in a multiple displacement engine involving oil aeration includes detecting engine speed. Once the engine speed has been determined, a delay period is established prior to enabling cylinder deactivation. The delay period is a function of whether engine speed exceeds a preselected threshold and an amount by which the threshold is exceeded. When the delay period expires, a request is generated for cylinder deactivation.

摘要： In an internal combustion engine adapted to operate in a cylinder-deactivation mode, a method for controlling the reactivation of a deactivated cylinder includes determining a difference between a torque request from a vehicle operator, and an estimate of a maximum engine torque achievable in cylinder-deactivation mode based at least in part on a current engine speed. The difference is integrated over time to obtain a torque request “error.” A reactivation of the deactivated cylinder is triggered when the torque request error exceeds a first threshold value, which can be a calibrated value, a calibrated value adapted, for example, for driving style, or a value determined from a vehicle operating parameter such as vehicle speed. The use of the torque request error advantageously avoids reactivation of the deactivated cylinders in response to brief transients in the torque request signal that otherwise temporarily exceed the maximum achievable engine output torque.

摘要： A method for controlling the operation of a deactivatable valve lifter of an internal combustion engine includes determining a first measure of heat loss from one or more components associated with a given deactivated cylinder based, for example, on the number of engine cycles that have occurred since cylinder deactivation. The given cylinder is reactivated when the component heat loss measure reaches a threshold level, as by comparing the first measure to a first predetermined threshold value. After cylinder reactivation, the given cylinder can thereafter be deactivated only after the temperature of the components has been restored to a nominal operating temperature, for example, as inferred from a second measure, representing the heat generated within the given cylinder subsequent to cylinder reactivation, determined based upon engine mass air flow or fuel flow. In this manner, the respective temperatures of such engine components are maintained above a desired minimum temperature.

摘要： A method for controlling airflow in an intake manifold of a multiple-displacement engine during an engine displacement mode transition includes determining, before a displacement mode transition, a post-transition mass air flow rate necessary to maintain a pre-transition engine torque output, as well as an airflow transient multiplier based on engine speed and an estimated post-transition manifold air pressure. After multiplying the requested mass air flow rate with the transient multiplier, the resulting compensated requested mass air flow rate is divided by a maximum mass air flow rate to obtain a requested percent airflow. The percent airflow is thereafter used with engine speed to determine a requested post-transition manifold air pressure-to-barometric pressure ratio, for example, using a lookup table; and the requested post-transition pressure ratio is used to determine a transient post-transition throttle position, to which an engine throttle will be moved upon initiating the displacement mode transition.

摘要： An arrangement for determining purge valve flow tolerance for use with evaporative emissions control systems includes developing an equation based on data relating purge valve duty cycle to flow, wherein the equation describes a flow curve with reference to a first axis and a second axis. The arrangement further includes using the equation as a base equation for flow, and adapting the equation for part-to-part tolerance as a function of an intercept point of the equation with respect to the first axis, wherein the first axis relates to duty cycle.

摘要： Prior to transitioning a multiple-displacement engine from a full-displacement engine operating mode to a partial-displacement engine operating mode, a base slip rate of a torque converter coupled to the engine engine is increased by a predetermined slip rate offset. The engine is then transitioned to partial-displacement mode upon the earlier of either achieving the desired offset slip rate, or once a maximum time delay has occurred since the slip rate offset was enabled. An offset slip rate is maintained throughout partial-displacement engine operation, and through a transition back to a full-displacement mode. The slip rate offset is removed or disenabled once the engine is again operating in the full-displacement mode. The slip rate offset is either a calibratable constant or is determined as a function of one or more suitable engine or vehicle operating parameters affecting vehicle NVH levels, such as engine speed and vehicle speed.
