    • A system and method for improving vehicle performance on a grade comprises an engine, an acceleration sensors a global positioning system, a controller and a torque transfer device. The controller determines the grade from information obtained from the global positioning system and the accelerator sensor. The controller calculates a dynamic weight shift of the vehicle from a first wheel to a second wheel due to acceleration and a static weight shift of the vehicle from the first set of wheels to the second set of wheels due to gravity and the grade. The controller then determines the maximum amount of torque that can be transmitted to the first wheel before the first wheel slips and avoids slipping by preemptively diverting torque from the first wheel to the second wheels before the first wheel slips.
    • 用于提高车辆性能的系统和方法包括发动机,加速度传感器,全球定位系统,控制器和扭矩传递装置。 控制器根据从全球定位系统和加速度传感器获得的信息确定等级。 控制器由于重力和等级,由于车辆从第一组车轮到第二组车轮的加速度和静态重量偏移而计算车辆从第一车轮到第二车轮的动态重量偏移。 然后,控制器确定在第一车轮滑行之前可以传递到第一车轮的最大扭矩量,并且在第一车轮滑行之前通过将第一车轮的转矩预先转向第二车轮来避免滑倒。
