摘要： A protection control selection unit is provided. The protection control selection unit selects control that uses one of a completely engaging heat generation amount and a releasing heat generation amount, by which the amount of heat that is generated in a lockup clutch is reduced. The completely engaging heat generation amount is generated in the lockup clutch in a period before the lockup clutch is completely engaged from a state of lockup engagement control. The releasing heat generation amount is generated in the lockup clutch in a period before the lockup clutch is released from the state of the lockup engagement control. Thus, an increase in the temperature of the lockup clutch at the time when the lockup clutch is completely engaged or released from the state of the lockup engagement control is suitably suppressed.

摘要： A method for monitoring a transmission range selector connected to a transmission of a powertrain system is described. The transmission range selector indicates one of a plurality of ranges including Park, Reverse, Neutral, and Drive. The method includes, upon detecting a change in a target transmission range, monitoring whether a signal output from an on-board sensor indicates an achieved range position of the transmission. When the signal output from the on-board sensor does not indicate that the target transmission range has been achieved, monitoring a transmission incorrect direction metric, monitoring a transmission unintended propulsion metric, and monitoring a metric associated with achieving the target transmission range. A fault is detected when any one of the transmission incorrect direction metric, the transmission unintended propulsion metric and the target range achievement elapsed time metric is exceeded.

摘要： A method for monitoring a fixed-gear transmission includes deriving a node speed relationship for each of the planetary gear sets based upon a center distance and a gear ratio and determining equivalent speed parameters for nodes of the planetary gear sets based upon a transmission input speed state, an intermediate node speed state and a transmission output speed state. A clutch slip speed relationship is determined for each of the clutches based upon the node speed relationships for the planetary gear sets and the equivalent speed parameters for nodes of the planetary gear sets. Rotational speed sensors monitor the input transmission speed, the intermediate node speed and the transmission output speed. A clutch slip speed for each of the clutches is determined based upon the respective clutch slip speed relationship and the monitored input transmission speed, the monitored intermediate node speed and the monitored transmission output speed.

摘要： The rate of change of transmission output torque is computed based on the differential speeds of the axles and of the transmission output shaft adjusting for final drive ratio. The speed of the axle is measured by an anti-lock braking system and communicated to the transmission controller over a communications bus. To compensate for the delay introduced by the communications bus, a shift register delays the signal from the transmission output shaft speed sensor. The resulting estimate of rate of change of transmission output torque may be used directly to control the torque capacity of one or more transmission clutches. Additionally, the resulting estimate may be combined with an independent output torque estimate to yield a more accurate output torque estimate.
摘要翻译： 变速器输出扭矩的变化率是根据轴的差速和变速器输出轴调整的最终传动比来计算的。 轴的速度由防抱死制动系统测量，并通过通信总线传送到变速器控制器。 为了补偿由通信总线引入的延迟，移位寄存器延迟来自变速器输出轴速度传感器的信号。 所得到的变速器输出转矩变化率的估计可以直接用于控制一个或多个变速器离合器的转矩容量。 另外，所得到的估计可以与独立的输出转矩估计组合以产生更准确的输出转矩估计。
