Title: (EN) FOUR-WHEEL DRIVE VEHICLE CONTROL SYSTEM AND METHOD
(ZH) 四轮驱动车辆控制系统和方法
Abstract: front page image
(EN) A method and a system are provided for operating a four-wheel drive powertrain of a vehicle. In one example, a method may comprise the steps of responding to a desired shift from a four- wheel drive mode to a two wheel-drive mode; decreasing a transfer case torque output to a secondary driveline to a lower first level and disengaging a disconnect device of the secondary driveline; increasing the transfer case torque output from the lower first level to a higher second level over a duration; after the duration, reducing the transfer case torque.
(ZH) 本发明提供了用于操作车辆的四轮驱动动力系统的方法和系统。在一个示例中,一种方法可以包括:响应于需要从四轮驱动模式转换至两轮驱动模式:将分动器输出至二级动力传动系统的扭矩减小至较低的第一水平并且使二级动力传动系统的断开装置分离;在持续时间内将分动器输出的扭矩从较低的第一水平增加至较高的第二水平;并在该持续时间后,减小分动器扭矩。
