摘要： A vehicle drivetrain can include a primary pair of drive wheels and a secondary pair of drive wheels and can be selectively switched between a two-wheel drive mode and a four-wheel drive mode. When the drivetrain is in the two-wheel drive mode, the secondary pair of wheels are disconnected from the prime mover and the multi-ratio transmission. Also, when the drivetrain is in the two-wheel drive mode, the components used to drive the secondary pair of drive wheels can be rotationally isolated from each of the secondary pair of wheels, the prime mover and the multi-ratio transmission.

摘要： A system and method for controlling a powertrain of a vehicle having an engine configured to output a variable torque, can include a transmission with a plurality of gear ratios and selectively driven by the variable torque, and a pair of wheels selectively driven by the transmission. The system can include a longitudinal acceleration sensor and a controller. The controller can be in electrical communication with the longitudinal acceleration sensor. The controller can be configured to determine an inertial value of the vehicle based on data from the longitudinal acceleration sensor prior to a shift from one of the plurality of gear ratios to another of the plurality of gear ratios. The controller can also be configured to determine a first estimate of a real-time torque value based on at least one of an engine map, the plurality of gear ratios, a torque converter map and driveline losses, and to determine a second estimate of a real-time torque value based on the inertial value and data from the longitudinal acceleration sensor, during the shift from the one of the plurality of gear ratios to the another of the plurality of gear ratios.
摘要翻译：用于控制具有被配置为输出可变转矩的发动机的车辆的动力系统的系统和方法可以包括具有多个齿轮比并由可变转矩选择性地驱动的变速器以及由变速器选择性地驱动的一对车轮。该系统可以包括纵向加速度传感器和控制器。控制器可以与纵向加速度传感器电连通。控制器可以被配置成基于来自纵向加速度传感器的数据，在从多个齿轮比中的一个变速到多个齿轮比中的另一个之前，来确定车辆的惯性值。控制器还可以被配置为基于发动机映射图，多个变速比，变矩器图和传动系损耗中的至少一个来确定实时转矩值的第一估计，并且确定第一估计值在从多个齿轮比中的一个换档到多个齿轮比中的另一个的换档期间，基于来自纵向加速度传感器的惯性值和数据的实时扭矩值。
