    • A vehicle automatic speed change power transmission control includes a control arrangement with overshoot/undershoot protection logic. The control is used with an electro-hydraulic pressure control module featuring a linear solenoid, and which supplies a hydraulically-actuated clutch configured to effect gear changes. The overshoot/undershoot protection logic is configured to detect when a commanded increase/decrease clutch pressure satisfies a clutch pressure threshold and to then activate the protection logic. Once the protection logic is activated, large command pressures increases/decreases are implemented in a series of stages having variable gains. The first stage has an aggressive gain and achieves 50-80% of the commanded clutch pressure. The second stage has a reduced gain and achieves 90% of the commanded clutch pressure. The third stage has a still further reduced gain and achieves about 100% of the commanded clutch pressure.
    • 车辆自动变速动力传递控制包括具有过冲/下冲保护逻辑的控制装置。 该控制用于具有线性电磁阀的电液压力控制模块,并提供配置成实现变速的液压致动离合器。 过冲/欠冲保护逻辑被配置为检测指令的增加/减少离合器压力何时满足离合器压力阈值并且然后激活保护逻辑。 一旦保护逻辑被激活,则在具有可变增益的一系列级中实现大的指令压力增加/减少。 第一阶段具有积极的增益,达到指定离合器压力的50-80%。 第二阶段的增益减小,达到指定离合器压力的90%。 第三阶段进一步减小增益,达到约100%的指令离合器压力。

    • A method of estimating the quantity of secondary reaction airflow supplied to the exhaust manifold of an internal combustion engine by an air injection reaction (AIR) system models airflows in an AIR pump, an AIR valve, and a plenum coupling the pump to the valve. The pump flow is modeled based on the pump speed (or pump motor voltage), the pump inlet air temperature and the pressure ratio across the pump, and the valve flow is modeled based on the pressure ratio across the valve and the valve inlet air temperature. The plenum pressure used in the pump and valve pressure ratios is modeled based on the net plenum airflow and the plenum air temperature. The estimated AIR airflow is useful for managing the air/fuel ratio in the engine exhaust system and enhancing the reliability of AIR diagnostics.
    • 通过空气注射反应(AIR)系统估计供应到内燃机的排气歧管的二次反应气流的量的方法来模拟在空气泵,气阀和将泵连接到阀的气室的气流。 泵流量基于泵速度(或泵电机电压),泵入口空气温度和泵两端的压力比建模,阀流量基于阀门和阀入口空气温度之间的压力比建模 。 在泵和阀压力比下使用的增压室压力基于净气室气流和增压空气温度进行建模。 估计的空气气流对于管理发动机排气系统中的空气/燃料比是有用的,并且增强了AIR诊断的可靠性。
