Abstract: A hybrid vehicle includes an electric motor and a combustion engine. A K0 clutch couples the combustion engine to a drivetrain of the vehicle. A control module of the vehicle calculates a torque to be applied by the motor to the K0 clutch when initiating engagement of the combustion engine to the drivetrain. The control module calculates two separate torque lead values by two separate methods and calculates the torque by combining the two torque lead values.

Abstract: Methods and systems for improving operation of a vehicle driveline that includes an engine and an automatic transmission with a torque converter are presented. In one non-limiting example, the engine may be stopped while a vehicle in which the engine operates is rolling. A transmission coupled to the engine may be shifted as the vehicle rolls so that vehicle response may be improved if a driver requests an increase of engine torque.

Abstract: A manual transmission is partially automated by utilizing a controller to regulate the torque capacity of the clutch. Under most circumstances, the controller manipulates the clutch according to driver manipulation of a clutch pedal to simulate a non-automated manual transmission. However, to save fuel, the controller may enter a sailing mode in which the clutch is disengaged without the driver depressing the clutch pedal. The controller exits sailing mode in response to the vehicle speed decreasing below a threshold which is a function of the currently selected gear ratio. The threshold is selected such that the engine will not stall and will be able to generate sufficient power for acceleration when the clutch is re-engaged to exit sailing mode. In order to extend the use of sailing mode, the controller may activate a downshift indicator at a slightly higher speed threshold to encourage the driver to downshift.
Abstract translation: 通过使用控制器来调节离合器的扭矩容量，手动变速器是部分自动化的。 在大多数情况下，控制器根据驾驶员操纵离合器踏板来操纵离合器以模拟非自动手动变速器。 然而，为了节省燃料，控制器可以进入其中离合器分离而不使驾驶员压下离合器踏板的航行模式。 控制器响应于车速降低到低于当前选择的传动比的函数的阈值而退出航行模式。 选择阈值使得当离合器重新接合以退出航行模式时，发动机不会失速并且能够产生足够的加速功率。 为了延长航行模式的使用，控制器可以以略高的速度阈值激活降档指示器，以鼓励驾驶员降档。

Abstract: A control system including a method and apparatus for operating a hybrid vehicle. A disconnect clutch selectively separates an electric machine from a combustion engine. If a wide open throttle or high torque command is requested and the combustion engine is shut down, a 12 volt starter may be used to start the combustion engine while disconnected from the electric machine and all of the electric machine torque available may be used for traction.

Abstract: Impeller speed, which is difficult to measure when a torque converter includes an impeller clutch, is estimated based on a known relationship among impeller speed, turbine speed, and turbine torque. Turbine torque may be directly measured by a turbine torque sensor or estimated based on other measurements such as output shaft torque or vehicle acceleration. The relationship is stored in a controller in terms of the coefficients of a second order polynomial relating turbine torque to impeller speed and turbine speed. A slip speed is calculated based on a measured input shaft speed and the estimated impeller speed. Closed loop control is used to adjust the impeller clutch torque capacity to maintain a target slip.
Abstract translation: 基于叶轮速度，涡轮转速和涡轮扭矩之间的已知关系来估计当扭矩转换器包括叶轮离合器时难以测量的叶轮速度。 涡轮扭矩可以由涡轮扭矩传感器直接测量，或者基于诸如输出轴扭矩或车辆加速度的其它测量来估计。 根据关于涡轮转矩与叶轮速度和涡轮转速的二阶多项式的系数，将关系存储在控制器中。 基于测量的输入轴速度和估计的叶轮速度计算滑移速度。 闭环控制用于调整叶轮离合器扭矩容量以保持目标滑移。
