    • An apparatus for controlling a differential limit torque produced in a differential provided in an automotive vehicle. During vehicle deceleration, a required differential limit torque value is calculated based on the vehicle deceleration. When a decrease is detected in the required differential limit torque value, a target value for the differential limit torque is calculated based on the required differential limit torque value through a filtering process employing a first filter having a slow output response with respect to the required differential limit torque value decrease in the presence of vehicle braking or a second filter having a fast output response with respect to the required differential limit torque value decrease in the absence of vehicle braking. The differential limit torque is controlled to the calculated target value.
    • 一种用于控制在机动车辆中提供的差速器中产生的差速限制转矩的装置。 在车辆减速期间,根据车辆减速度计算出所需的差速限制转矩值。 当在所需的差动极限转矩值中检测到减速时,通过使用具有相对于所需差速器的低输出响应的第一过滤器的滤波处理,基于所需的差动转矩转矩值来计算差分极限转矩的目标值 在没有车辆制动的情况下,在存在车辆制动的情况下,限制转矩值减小或具有相对于所需差速器极限转矩值的快速输出响应的第二过滤器减小。 差速限制转矩被控制到计算出的目标值。
