The invention relates to a control device for operating a road-coupled all-wheel drive vehicle, comprising at least one electronic control unit, the all-wheel drive vehicle comprising at least one first drive motor associated with a primary shaft as a primary motor and at least one second drive motor associated with a secondary shaft as a secondary motor. According to the invention, the control unit has a gradient limiting module for performing a torque gradient limiting function, in such a way that, when a target all-wheel drive coefficient varies on the basis of a defined driver-desired signal, a new target all-wheel drive coefficient is first determined in a stepped manner and, in the following range of all-wheel drive coefficient adjustments, the gradient of the driver-desired signal forms a gradient limit for the maximum allowable adjustment of the torque of the main motor and/or of the secondary motor and preparing.
本发明涉及一种用于运行道路耦联式全轮驱动车辆的控制装置,所述控制装置包括至少一个电子控制单元,该全轮驱动车辆包括至少一个分配给主轴的第一驱动马达作为主马达和至少一个分配给副轴的第二驱动马达作为副马达。根据本发明,所述控制单元具有用于执行扭矩梯度限制功能的梯度限制模块,使得在目标全轮驱动系数基于定义的驾驶员期望信号变化时首先阶跃式地预定新的目标全轮驱动系数并且其次在接下来的全轮驱动系数调节的范围中驾驶员期望信号的梯度构成用于主马达和/或副马达扭矩的最大允许调节的梯度限制。
