    • An automobile differential limiting torque control system with a limited slip differential mounted between right and left drive road wheels for limiting a differential action, comprises sensors for detecting a vehicle speed and an accelerating degree of the vehicle, and an active limited slip differential controller responsive to the accelerating degree for deriving a target torque value for the differential limiting torque. The controller derives the slip difference between a vehicle-speed dependent allowable slip limit and an actual slip amount at an outer wheel of the right and left drive road wheels during cornering of the vehicle in the presence of depression of the accelerator pedal. The controller includes a filter responsive to the slip difference, for filtering the derived target torque value so that the actual slip amount is maintained within the allowable slip limit through a filtering process which sets a limit to a decrement of a previous control command when the actual slip amount exceeds the allowable slip limit, and sets a limit to an increment of the previous control command when the actual slip amount is less than and close to the allowable slip limit. The controller adjusts the differential limiting torque to the filtered target torque value.
    • 安装在左右驱动车轮之间的用于限制差速动作的限滑差速器的汽车差速器限位转矩控制系统包括用于检测车辆速度和车辆加速度的传感器,以及响应于 用于导出差动限制转矩的目标转矩值的加速度。 控制器在存在踩下加速踏板的情况下,在车辆转弯期间,得出车辆速度相关允许滑移极限与左右驱动车轮外轮之间的滑差。 控制器包括响应于滑移差的过滤器,用于过滤导出的目标扭矩值,使得通过过滤处理将实际滑移量保持在可允许滑移限度内,当过滤过程对实际的控制命令设定对先前控制命令的减小的限制时 滑移量超过允许滑移极限,并且当实际滑移量小于并接近允许滑移极限时,将先前控制指令的增量设定为极限。 控制器将差速限制转矩调整到过滤的目标转矩值。

    • A driving torque distribution control system for a four wheel drive vehicle includes a torque distributing clutch provided in a drive path for the front wheels, and a controller for controlling a driving torque transmitted to the front wheels through the clutch, in accordance with a corrected front and rear wheel speed difference which is a difference resulting from subtraction of a dead band from a sensed actual front and rear wheel speed difference. In order to improve the controllability near the cornering limits of the vehicle without deteriorating the driving ability in a low lateral acceleration cornering operation, the controller sets the dead band so that the dead band increases as the lateral acceleration of the vehicle increases.
    • 用于四轮驱动车辆的驱动扭矩分配控制系统包括设置在前轮的驱动路径中的扭矩分配离合器,以及控制器,用于根据校正前方控制通过离合器传递到前轮的驱动扭矩 以及作为从所感测到的实际前轮和后轮速度差中减去死区导致的差异的后轮速度差。 为了提高车辆的转弯极限附近的控制性,在低横向加速转弯操作中不会降低驾驶能力,所以控制器设定死区,使得死区随着车辆的横向加速度的增加而增加。
